Changelog

Each section below comes from CHANGELOG.md in the repository, read when this site was built. Unreleased is what this build has that the last npm release does not. A version heading, such as 0.1.0, names the day its packages were published to npm. A version that the opening note calls prepared, and not published yet, names its planned tag day instead. Contract builds have their own record, the code hashes in contracts/code-hashes.json.

All notable changes to this repository: the NEAR contracts in contracts/, the npm packages @probarion/core, @probarion/sdk, probarion (the CLI) and @probarion/mcp (the MCP server, in packages/mcp), and the web console in apps/web.

Versions follow semver. The npm packages share one version, released by the tag sdk-v<version>; 0.1.0 was published on 2026-11-09, and 0.1.1, the first release of @probarion/mcp, on 2026-11-11. A contract crate carries its own version, and each build of it is identified by the code hash of its reproducible build in contracts/code-hashes.json. The web console is not versioned yet, and it deploys from main to https://probarion.xyz. While the version is 0.x, a minor version may change the API. The software is an unaudited beta.

Unreleased#

Added#

• probarion verify --invoice <file> (repeatable) and --invoices <dir> (every .txt file of a folder) run A8 with invoice texts the auditor holds, live or with --offline, in the CLI built from this repository; release 0.1.1 on npm does not have them. The CLI reads each file on the auditor's computer, keys it by the sha256 of its bytes, and uses it for A8 only: it is not sent, not written to --snapshot and not printed (--json adds an invoices list with each file's sha256 and the ledger entries it matches). A file that matches no attested decision is listed under the rows and on stderr, and does not fail the run. A file or folder that cannot be read, a folder with no .txt file, or a file that is not UTF-8 text is a usage error (exit 64). --system-prompt <file> (repeatable) adds a system prompt A8 accepts besides the standard one, for a decision made under an agent's own model.systemPrompt. On 2026-11-12 the offline run on the demo vault's snapshot of 10:28:54 UTC with --invoices docs/evidence/demo-vault passed checks a to i, and check e found that A8 passes on all five attested decisions, entries 10 to 13 and 15 (docs/evidence/demo-vault/verify-a8-2026-11-12.txt). A live run with --online 26 seconds later passed checks a to i, A8 on the same five, and O1 and O2 on all five, entry 15 among them (verify-online-a8-2026-11-12.txt). The TEE measurement is not pinned, so this does not show which model image ran. docs/evidence/demo-vault/README.md adds a dated section, pnpm judge adds the offline step verify-demo-a8, which runs that command and compares it with the committed output, and the docs, SECURITY.md and the README say that A8 passed on the demo vault's five and was not run on the Canary's two.

• The proof page checks the TEE live: a "Check the TEE now" card after the decisions, the same on every vault's page. The visitor's browser draws a 32-byte nonce and sends it, with no cookie and no Referer, to a new route, GET /api/tee/check; nothing the visitor typed or uploaded goes with it. The route asks NEAR AI Cloud's public attestation report for that nonce, with no API key, for NEARAI_MODEL, the model Payables is set to use, or, when it is unset, for the SDK's preferred private models in order until one answers. It checks up to four model attestations in the report, and says how many the report holds: the nonce in report_data[32..64] and request_nonce, the signing address in report_data[0..32], O1 (Intel DCAP on the TDX quote, held to the SDK's policy) and O2 (the GPU payload carries the nonce, and NVIDIA NRAS verifies it). The browser checks both bindings again with its own nonce, and the card shows the worse of its verdict and the server's. A check that cannot run in time (12 seconds for NEAR AI's report, 24 in all) is unavailable, not a pass or a fail. The card checks the TEE that serves the model now, not the decisions above it, which keep their checks A1 to A7, and the TEE measurement is not pinned. The route passes on five values per attestation, and their count, and nothing else of the report (about 290 KB). Its rate limit, teeCheck, is one counter of 30 a minute for all visitors together, so it stores nothing about a visitor, and a call that another site's page makes in a browser (Sec-Fetch-Site) answers 403 bad_origin without spending it. @nearai/inference-sdk 0.2.1, until now an optional dependency of the CLI and an optional peer of the SDK, is a dependency of the web app, loaded by a literal import so the build traces it, with @phala/dcap-qvl, into the route. On 2026-11-12 a local production build of this change answered three calls for Qwen/Qwen3.8-27B with all four checks passed, in 1.8 to 10.1 seconds, and a cross-site call with 403 bad_origin, recorded in docs/evidence/tee-check/route-2026-11-12.json. After the promote of 2026-11-12 (#138, main b3baa82), probarion.xyz did the same: its first call at 18:39 UTC, the card in a browser at 18:40 UTC and three scripted calls at 18:42 UTC (1.4 to 1.6 seconds) passed all four, and a cross-site call answered 403 bad_origin, recorded in docs/evidence/tee-check/live-2026-11-12.json.

• The demo video is posted on X, in the build's demo post of 2026-11-12: https://x.com/probarionhq/status/2120882499689836651 (opens in a new tab). It is a 1:57 cut recorded on the live product, on NEAR testnet with test USDC. The README links it from its top row of links and from the filmed run in "On-chain proof", and docs/evidence/demo-vault/README.md links it from the section on that run.

• Payables paid a second invoice on its own with an attested model, on testnet on 2026-11-12 at 09:52 UTC, in a run filmed for the demo video, recorded in a new section of docs/evidence/demo-vault/README.md. invoice-INV-2010.txt (2.00 test USDC under PO-1001) went in on the demo vault's Payables page, signed in as the owner, while probarion.xyz ran main as promoted by PR #130. Qwen/Qwen3.8-27B proposed paying it (confidence 0.98) with the mandate's account in address next to the chain base, the shape entry 12 was refused for on 2026-11-11. PR #120 takes that shape as the mandate's payee, so every code rule passed, and ledger entry 15 records allow, decided by model+rules. The agent key sent spend 5, which paid 2.00 test USDC to probarion-payee.testnet, entry 16 records it paid, and anchor 12 covers all 17 entries. Mandate 1 is now exhausted (5 of 5 uses, 14 of its 20 test USDC), and the vault held 11 test USDC after the run. At 10:05 UTC the owner froze and unfroze the vault from the console, signed in Meteor (the unfreeze with 1 yoctoNEAR), a second dated record after the one of 2026-11-11; get_config read frozen: false after. The proof page's snapshot of 10:28:54 UTC passes checks a to i offline with the repository's CLI (9 passed, 0 failed, 0 unproven): check d finds 5 spends on chain, each bound to its own decision, and check e finds 5 attested decisions that pass A1 to A7. The online run of 2026-11-12 was at 01:10 UTC, before entry 15, so its O1 and O2 cover entries 10 to 13. The TEE measurement is not pinned, so this does not show which model image ran, and A8 was not run. Those are two invoices with test tokens, and Payables has not run on mainnet. docs/evidence/demo-vault/ adds the invoice, the ledger of 17 entries (ledger-2026-11-12-video.jsonl), the snapshot and the offline verify output; pnpm judge checks the new snapshot offline (verify-demo-snapshot-1112-video) and now checks that the live ledger starts with ledger-2026-11-12-video.jsonl; docs/mainnet-proof.json records the spend, the anchor, the freeze and the unfreeze as testnet transactions. The landing page's NEAR AI Cloud row now gives 7 published attested decisions on testnet (2 on the Canary, 5 by Payables), 6 of which passed O1 and O2 online, and two invoices paid, and links entries 13 and 15 on the proof page. The README's Status rows for the NEAR AI Cloud adapter, Payables and the web console, its NEAR AI Cloud row and demo vault section, SECURITY.md, the threat model, the comparison page, the privacy page and the docs pages that named one paid invoice say what ran. The README's step 5 adds that mandate 1, the demo vault's one mandate, has had no uses left since 09:52 UTC, so the contract refuses the MCP demo's three dry runs.

• A console try on testnet on 2026-11-12, from 03:29 to 03:36 UTC, on trial.vaults.probarion.testnet, recorded in a new section of docs/evidence/trial-vault/README.md. Claude drove the console at probarion.xyz in the owner's Chrome, and the owner signed six wallet prompts in Meteor. The owner signed mandate 2 on the Mandates tab (2 test USDC in all, held above 0.5 USDC). The same real MCP client as on 2026-11-11, Claude Code run headless with @probarion/mcp 0.1.1 from npm, asked for 1.00 test USDC under it for INV-3004, and the vault held it as spend 4. On the approval page Claude clicked Reject and the owner signed reject: nothing was paid, and the reservation went back to the mandate. Then the owner revoked mandate 2 on the Mandates tab, added a spare agent key that the Keys tab generated and removed it on the same tab, and withdrew the vault's whole balance, 1 test USDC, with Withdraw all on the Overview. The spare key's label is payablesconsole-try-spare, because the label field already held payables when Claude typed after it. After the run the vault held no USDC, spend 4 was rejected, mandate 2 was revoked, and mcp-claude was again its only agent key. A live npx -y probarion@0.1.1 verify of the 8 ledger entries passed checks a to i (9 passed, 0 failed, 0 unproven), and the ledger's entry for spend 4 still says held, since no code writes an owner's or an approver's action to the ledger. The decision is rules-only, the prompt gave every tool argument, the owner is also the approver who rejected, every step was in a desktop browser, and this record does not check a Telegram message for spend 4. Adding an email alert, the Base top-up through 1Click and any change of the ledger key were not tried. The evidence folder now holds the invoice, the ledger, the snapshot, the offline verify output and the client's tool calls of that run; pnpm judge checks the new snapshot offline, and docs/mainnet-proof.json records its 8 testnet transactions. The landing page's status list moves Reject, revoke, withdraw and key removal to the console's tried row, and its other row is now "Web console: email alerts, Base top-up". The README's Status rows for the web console, the MCP server and the approval page, and the docs pages on what works today, holds and approvals, roles and keys, testnet and mainnet, the architecture and letting an agent pay say what was tried.

• The landing page has a "Built on NEAR, with NEAR AI Cloud" section after the status list. One card holds a row for NEAR, where payments are made (the vault and the factory on testnet, and v0.probarion.near on mainnet with 1 payment and 1 refusal and no Base payout yet), and one for NEAR AI Cloud, the model that advises (7 attested decisions that pass A1 to A7 offline, 6 of which passed O1 and O2 online, the two invoices Payables paid on its own on 2026-11-12, and the TEE image not pinned); each row links its evidence. Under the card, four cards name where Probarion ships: the npm public registry (probarion, @probarion/core, @probarion/sdk and @probarion/mcp 0.1.1, with provenance), the official MCP Registry (io.github.probarion/probarion 0.1.1), GitHub (the MIT source and the CI with the sandbox tests and the reproducible build) and the Chrome Web Store (the extension 0.1.0, shown with Probarion's own mark). NEAR's unmodified logo stands in for its name; the npm, MCP and GitHub logos sit unmodified above their cards' names and are hidden from screen readers, which read the names. The section ends with the Intel TDX and NVIDIA NRAS checks of verify --online, a line that no payout has run through NEAR Intents yet, and the trademark notices, which say no partnership or endorsement is implied. The README's License line now says Probarion is designed to pay through Base and Solana, since no payout has run there, and the 0.1.1 release row links the registry listing. apps/web/test/built-on.test.ts holds each fact to the README, the evidence, the ledgers and the package files, checks every link offline, and pins the paths of each logo to its owner's file.

• The Payables agent paid an invoice on its own with an attested model for the first time, on testnet on 2026-11-12, recorded in docs/evidence/demo-vault/README.md. At 01:09 UTC invoice-INV-2009.txt, 2.00 test USDC to probarion-payee.testnet under PO-1001, went in on the demo vault's Payables page, signed in as the owner; Claude drove the console in the owner's browser, and no wallet signature was needed. With NEARAI_MODEL set to Qwen/Qwen3.8-27B, the model proposed paying it (confidence 0.98) with the payee in near_account and no chain or address, every code rule passed, and ledger entry 13 records allow, decided by model+rules. The agent key sent spend 4, which paid 2.00 test USDC to the mandate's payee, entry 14 records it paid, and the ledger key anchored all 15 entries. Mandate 1 had then spent 12 of its 20 test USDC and had 1 of its 5 uses left. That payee hint did not depend on PR #120: the rule took that shape as the mandate's payee before the fix too. The payee hint differed in each of entries 10 to 13, by two models (z-ai/glm-5.3-flash for 10 and 11, Qwen/Qwen3.8-27B for 12 and 13). A live verify with release 0.1.1 of the 15 entries passed checks a to i (9 passed, 0 failed, 0 unproven), and check e found 4 attested decisions that pass A1 to A7; with --online all four passed O1 and O2. The TEE measurement is not pinned, so this does not show which model image ran, and A8 was not run. It is one invoice with test tokens, Payables has not run on mainnet, and its reconcile job is still not built. docs/evidence/demo-vault/ holds the invoice, the ledger, the snapshot and both outputs, pnpm judge checks the snapshot offline, and docs/mainnet-proof.json records the spend and the anchor. The README's Status row for Payables is now Live on NEAR testnet, the landing page's status list shows it as "Live on testnet", and the NEAR AI Cloud rows, the demo vault's section, SECURITY.md, the threat model, the comparison page, the privacy page and the docs say what ran; the docs pages that said no run of process() was recorded now name this one. pnpm judge then checked that the live ledger started with ledger-2026-11-12.jsonl.

• The owner run of 2026-11-11 on testnet, from the console at probarion.xyz with a real wallet (Meteor): Claude drove the console in the owner's browser and the owner signed each wallet prompt, recorded in docs/evidence/trial-vault/README.md. On the demo vault the owner froze and unfroze the vault from the console. On trial.vaults.probarion.testnet the owner sent 5 test USDC from the Top-up tab (the USDC transfer on NEAR; the Base top-up through 1Click was not tried), added the two keys that npx -y @probarion/mcp@0.1.1 init made, from the Agent (MCP) tab, and signed mandate 1 (at most 3 test USDC a payment and 5 in all, held above 1). A real MCP client, Claude Code run headless, then started @probarion/mcp 0.1.1 from npm with only PROBARION_VAULT_ID set: spend 1 paid 0.50 test USDC, spends 2 (2.00) and 3 (1.50) were held, and the owner approved both on the console's approval page, where each paid. The prompt gave the tool arguments, so the client read no invoice, and the decisions are rules-only. A Telegram chat linked from the Alerts tab got real bot messages, "Approval needed" for spend 3 and "Paid" for spend 2; no email was sent. Spend 1's payment and spend 2's hold got no message: the watcher had recorded them before the chat was linked, and alerts do not send events from before, so spend 3 was sent after the link to make one fire. The screenshots of the approvals are from a desktop browser, so a phone is not confirmed. The server's verify and a live npx -y probarion@0.1.1 verify passed checks a to i (9 passed, 0 failed, 0 unproven). The same day three invoices went through the demo vault's Payables with an attested model, and code refused all three with mandate.payee_mismatch, sending nothing: INV-2006 (ledger entry 10, z-ai/glm-5.3-flash) by a false positive that PR #116 fixed; its retry INV-2007 (entry 11, the same model) because the model's payee hint named acme-cloud.near, which is in neither the invoice nor the prompt; and INV-2008 (entry 12, with NEARAI_MODEL set to Qwen/Qwen3.8-27B) by a false positive again: the model put the mandate's own account in address next to the chain base, since the proposal schema has no NEAR chain (PR #120 fixes the rule for that case). So on 2026-11-11 the Payables agent had not yet paid on its own with an attested model. A live verify of that ledger passed checks a to i, and with --online entries 10 and 11 passed O1 and O2 (a later online run could not fetch Intel's quote collateral); docs/evidence/demo-vault/ holds the ledger, the snapshot, both outputs and the three invoices. The trial vault's evidence folder holds the run's ledger, snapshot, offline verify output and invoices and the client's tool calls; docs/mainnet-proof.json records the run's 14 testnet transactions. The README's Status rows for the web console, the MCP server (now Shipped), the watcher, the Telegram alerts and the approval page, the landing page's status list (the console's tried row adds the NEAR USDC top-up, the Agent (MCP) tab, Freeze and approvals, its other row now names Reject, revoking a mandate, Withdraw, removing a key, email alerts and the Base top-up through 1Click, and the MCP server row is Live) and the docs say what was tried.

• The first Probarion vault on NEAR mainnet, v0.probarion.near, ran on 2026-11-11 between 12:51 and 13:00 UTC: the 2026-11 demo path of docs/runbooks/mainnet-v0.md, with real USDC and small amounts. The owner signed every transaction in their own terminal and in Meteor, and Claude signed nothing. The owner created probarion.near, then the vault, deployed the CI wasm of commit 64ac3c0 (code hash 3cQXYDvfGLRMveCVAHmh1exiuZKDXWqD8cUhqdEs9MF1), initialized it with the mainnet constants and locked it by deleting its only full-access key. The owner registered it on native USDC, sent it 3 USDC, added a spend-only agent key and signed mandate 1, whose payee and approver is the owner's own Meteor wallet. Spend 1 paid 1 USDC under mandate 1 (INV-M001), and a spend against mandate 999 was refused on chain with PROBARION:NoMandate, with no USDC moved. The vault is standalone: no mainnet factory is deployed. Step 6 (the Intents top-up), the Base mandate and step 10 (the first Base payout) did not run: spike S1 is unproven, so no Base payout has run on mainnet. The spend's decision is pre-ledger, the sha256 of docs/evidence/v0-decision-m001.json, with no signed ledger and no attestation. contracts/deployments/mainnet.json records the vault's transactions, docs/mainnet-proof.json the seven the README cites, and AGENTS.md the two mainnet accounts. docs/evidence/mainnet-v0 holds the run's README, the output of a read-only verify of the vault on mainnet (8 passed, 0 failed, 0 unproven, 1 skipped, RESULT: PASS: checks a to h pass, and check i skips because there is no factory) and the snapshot it wrote, which pnpm judge verifies offline. pnpm judge also verifies the vault live, read-only, with the repository's evidence, and check-claims --online re-reads its code hash and access keys on mainnet. The README's Status row is Live on NEAR mainnet, its mainnet section gives the run and how to check it, and the docs, the landing page's status list, SECURITY.md, the threat model and the runbooks say what ran and what did not. The console and the proof pages still serve testnet only.

• The Canary page, /canary, has three one-click example messages above the textarea: an invoice for 50 USDC, "We changed banks" and "Ignore previous instructions". A chip fills in its fixed text, clears the last answer and stays pressed (aria-pressed) while the text is unchanged, and the line under the chips says what that text usually ends as, with the rule id. With a fully fooled model, the invoice is refused by code with mandate.over_per_payment and, in raw mode, by the contract with OverPerPayment; the other two are refused with mandate.payee_mismatch, and raw mode does not send them, since the contract's dry run would accept or hold them. The real model can answer otherwise. apps/web/test/db/canary-chips.test.ts pins those outcomes through the real cycle, with a fully fooled fake model and a fake chain holding the Canary's mandate. "Raw mode on" has a tooltip (on hover, focus or tap; Escape closes it) saying what raw mode sends and its limits: 1 per visitor every 10 minutes, 30 an hour in all. A refusal is given in words with its rule id in parentheses (apps/web/src/lib/canary/reasons.ts, one reason for each rule of the policy reference). A card under the form replays the team's attempt of 2026-11-10 in three steps: the model's 50 USDC, the code's invoice.amount_invalid and custom.canary_no_autopay, and the contract's OverPerPayment with its transaction. It is shown in every state of the page, and rehearsal.test.ts holds each of its values to docs/evidence/canary-vault. Rate limits, raw mode and the route are unchanged.

• Release 0.1.1 was prepared before its publish: @probarion/core, @probarion/sdk, probarion and @probarion/mcp are at 0.1.1, with a ## 0.1.1 section below. packages/mcp/server.json is the server's entry for the official MCP registry, io.github.probarion/probarion (schema 2025-12-11). pnpm release:check checks it against the tag and the package's mcpName, with --pack also against the mcpName in the packed @probarion/mcp manifest (the one the registry reads from npm), the tarball rule keeps it out of the npm package, and scripts/test/release-manifests.test.ts pins its environment variables to the ones packages/mcp/src/config.ts reads, with an absolute path for each file setting. docs/RUNBOOK.md has the OWNER's release steps: the annotated tag on main, the npm-release approval, the npm checks, then mcp-publisher with a token that can read the organization role, since the registry's device login cannot publish to an organization namespace yet, and how to finish a publish that stops at @probarion/mcp. The @probarion/mcp README said the server would be on npm once release 0.1.1 was published, and the README's Status table had a row for 0.1.1, In progress (both changed with the publish, under Changed).

• docs/comparison-2026-11.md: how Probarion compares with NEAR's Agent API, the x402 exact scheme on NEAR, AP2 and plain caps, cell by cell with the sources read on 2026-11-11, and what Probarion does not have (a budget per period per mandate, a USD budget, a timelock, webhooks, a gas relayer). The README has a four-row summary under "Why it is different".

• Known gaps (THREAT_MODEL, SECURITY, the MCP README): verify does not run the policy again, so a program that holds both the agent key and the ledger key can skip decide() and still pass, inside the mandate. Run @probarion/mcp as another OS user or in a container when the agent host has a shell tool, and keep PROBARION_AGENT_KEY and PROBARION_LEDGER_KEY out of a client config the agent can read.

• The Canary's signed ledger, published as evidence in docs/evidence/canary-vault: ledger-2026-11-10.jsonl, the vault's whole ledger as it stood on 2026-11-11, which the owner exported read-only: 5 entries from the team's own three attempts of 2026-11-10 and no visitor's. Beside it are snapshot-2026-11-11.json, the snapshot a live verify with that ledger wrote, and the run's output, verify-2026-11-11.txt, which passed checks a to i. Check e finds 2 decisions by NEAR AI Cloud's z-ai/glm-5.3-flash that are attested and signed and pass A1 to A7 offline. verify-online-2026-11-11.txt is a live run with --online the same day, at 07:43 UTC, which also passed the online checks O1 and O2 on both: each TDX quote is a genuine Intel TDX quote (Intel DCAP, debug off, an accepted TCB status, which can be OutOfDate) whose report data holds the signing address and the entry's nonce, and NVIDIA NRAS verified each GPU payload, which carries that nonce. The TEE measurement is not pinned, so this does not show which model image ran, and A8 was not run, since the ledger holds no invoice text. A first online attempt failed O2 with not_yet_valid, because the computer's clock was about 3 s behind NVIDIA's, and passed after a clock sync. The folder's README lists the 5 entries, with what the model proposed and what the code and the contract did, says what check e shows offline and online and what it does not, and gives the offline command, the live one and the online one; the live and online ones stop passing check c once the Canary anchors an entry the file does not have. The CLI's verify --offline refuses --online, so O1 and O2 do not run on the snapshot from the CLI; the SDK's verify({ snapshot, online: true }) runs them on a snapshot it is given. The README, SECURITY.md, the threat model and the docs pages that said no real attested decision was recorded now say this with its date and its limits, and link the evidence and the online output; those docs pages list both files among their sources. The privacy page and the home page's model step say it in short, with the date and the limits, and the status row "Live attested model run" reads "Checked online on testnet, image not pinned", and stays Preview. apps/web/test/canary-vault.test.ts runs the checks on the committed snapshot, holds the README's table to the ledger cell by cell, pins the online run's output, and pins what the README, SECURITY.md, the threat model, the privacy page, the docs pages, this entry and the rehearsal's rows say about it.

• pnpm judge (scripts/judge.mjs): one read-only command for a screener or a judge, run after pnpm install --frozen-lockfile. It builds the four packages, then runs steps 0 and 2 to 6 of the README's 5-minute evaluation, the eval check and the per-package tests of core, sdk, cli, mcp and examples/402. The claims check runs offline and online; the README's step 2 and step 4 snippets and its step 6 commands run as written, and their output is compared with the README's; verify --offline runs on every committed snapshot in docs/evidence; the demo vault, v0.probarion.testnet and the Canary are verified live, read-only, and the demo vault's live ledger must start with the committed one; the MCP demo and the 402 demo run. Each step quotes the README line it proves, found again at run time, and prints one row: PASS, EXPECTED-FAIL (the Canary verified without its ledger fails check c, and v0.probarion.testnet fails d and h, as the README says; any other result there is a FAIL), SKIPPED with the reason and the command, or FAIL. It exits 0 only when no step failed and writes judge-report.json (gitignored): the claim, README line, command, result, expectation, time and detail of each step, with the commit, Node and OS. --offline makes no network call, --quick skips the tests and --json prints the report. SKIPPED is only for a step not run here (the flags, the network down, a timeout, 429 or 5xx); a definite wrong answer, such as the proof page answering 404 or the MCP demo skipping its verify for that reason, is a FAIL, and the MCP demo row passes only when its 6 steps answer as expected or with a note. The package rows give the README's dated test count next to today's, and the examples/402 row checks that every test of test/pay-per-call.test.ts passed. Child processes get no PROBARION_* variable and no other variable named like a secret, the MCP demo runs with an empty home folder so its server finds no keys file, and a README snippet that names a key (or, in an offline step, reaches the network) is refused before it runs. AGENTS.md and the README's 5-minute section start with it, and .github/workflows/judge.yml runs pnpm judge --offline --quick daily and on pushes to main, with read-only permissions and the actions pinned at the SHAs of ci.yml. The web console's tests and the Rust tests are listed as known skips with their commands.

• The eval's adversary run: the model fully fooled. For each of the 20 invoices the proposal is what the invoice asks a fooled model to do (the attack's own amount, account and mandate for the six injected ones, the wrong action the invoice presents for the eight that must not be paid, the right action for the six clean ones), marked attested with confidence 1, through the same decide(), contract mirror, execute() and owner wait as the other runs. Offline and deterministic, with no model and no key. Result: "model fully fooled: money moved wrongly 0/20 (0.00 USDC)"; 14/20 proposals are wrong and the code's rules refuse all 14 (the contract layer, the checks.rs mirror's refusals only, stops 4 of them on its own, and the owner rule holds or refuses 8). eval/results/adversary.md gives every case's proposal, decision, contract answer, money (count and USDC) and stopping layers, with what each result assumes: I-02's injection is not shown to a model; D-01 is decided as if the intake guard missed it; P-01, P-02 and D-02 rest on one code rule each; and a model fooled only into approving the visible invoice pays I-02, I-04 and I-05 their own total (430.00 USDC to the mandate's payee), counted as paid rightly. A test tries over 5,000 other attested proposals across the 20 cases and finds none that moves money wrongly. eval:check holds the new file and latest.json to the code. The layer tables now label the contract row "contract (checks.rs mirror, refusals only)" and say why the payee cases are not among its stops: a spend names no destination, so the contract pays the mandate's payee. In the adversary run the extract layer counts only text that does not reach the code, since the adversary obeys I-02's injection although the reader drops it. The attack log gives each case's layers per run: the adversary line has its own, and the last line says which run it is for.

• @probarion/mcp gives the client server instructions for the model when it connects (the MCP instructions field; each client decides whether its model sees them), under 1,200 characters. Where a tool description or an answer note already states a rule, the instructions use the same sentence from a shared constant, and a test compares them, so those rules cannot drift; a few words of their own orient the model. The rules: only the payee of an active mandate bound to the server's key can be paid, with no recipient parameter; check_spend first when unsure, since it sends no transaction (its description now says so in those words); each ref and each invoice hash pays at most once; poll a held spend until it leaves held or its held_until passes, after which the contract approves no hold, and do not send it again (the request_spend note for a hold now says the same); an unconfirmed spend may have paid, so do not resend it under a new ref; a refusal is final for that request; burned is final for the vault and does not change, worded for the server's network. A server with no keys adds that request_spend is off, and that refusal now says no agent and ledger keys are set (a keys file counts too) in place of naming the two environment variables.

• /proof/<vault>/payments.csv: the vault's decisions as a spreadsheet, linked as "Download payments (CSV)" next to the snapshot download. One row per decision, newest first: date (UTC), mandate and label, the payee of the spend on chain (empty when nothing was sent), amount in USDC, the decision and why, each spend bound to it with its status on chain, when the snapshot read the chain, the spend transaction with its explorer link, the invoice's SHA-256 and the ledger seq. The header row is the same in every file, and the capture time is also in the file name. The file is the route's own snapshot, like snapshot.json, so it can be older or newer than the page's. RFC 4180 with a UTF-8 BOM and CRLF, and an apostrophe before any =, +, -, @, tab or CR that starts a cell: at the start of a field, and after a ; or a line break in it, for Excel in locales that split on semicolons. Same access and rate limit as snapshot.json. The HTTP API reference now lists the three proof files, and docs/evidence/demo-vault/payments-2026-11-09.csv is the demo vault's, made from its snapshot by a test. The Mandates docs page says the payee needs no NEAR: it only receives USDC, and there is no NEP-366 relayer.

• examples/402: negotiation, receipts and a one-line demo. The paywall has a list price and a floor (the least it takes, kept out of every answer), and POST /counter takes one counter per quote: below the quote and at or above the floor it answers with a new quote at the countered price; otherwise 409. When a quote is above what a live mandate can pay (its cap per payment, or what is left of its total when less), the agent counters once at that limit and pays the new quote, or walks away without calling request_spend; under a mandate with no payment left it does not counter, and Probarion's refusal names the reason. The payee still comes from the mandate, and the quote parser still refuses unknown lines. After a paid 200 the agent checks the data against a schema and the data_sha256 the seller states, and appends a line to receipts.jsonl (quotes, list and paid price, spend, what request_spend answered, transaction, ledger seq, check, time); a failed check is recorded as failed, and the money is not refunded. The paywall builds the paid answer before it marks the quote used, so data it cannot build leaves the payment redeemable. pnpm --filter @probarion/example-402 run demo runs a walk-away, a negotiated sale with its payout and a refused call on the SDK's test double chain, with no network and no keys, even when keys are in the environment, and prints its elapsed time (about a second here); run demo --testnet, with a vault and its keys in the environment, runs the same calls on testnet. On 2026-11-11 run demo --testnet ran on percall.vaults.probarion.testnet (spend 21 paid 0.01 for a 0.012 list price); its output, receipt, ledger, snapshot and verify report are in docs/evidence/402-vault.

• /proof/<vault> lists every decision of the ledger under the checks, newest first. For a decision made with model output it shows what the ledger records the TEE saw and signed, and what the code and the contract checked, with A1 to A7 run on the page's snapshot and a fixed line on what they leave open: the TDX quote needs verify --online, A8 needs the invoice. Each card has the audit anchor #seq-N, and #spend-N for each spend bound to it, and check (e) links to the section. Past the newest 20, a decision shows its summary line and anchors; ?seq=N opens its full card.

• The console's Payables invoice page links its decision's card on the vault's proof page (Audit link) when that page is public.

• scripts/check-claims.mjs (pnpm check:claims), a checker of the README's claims that runs straight after git clone with Node alone: no install, no build and, offline, no network. It reads README.md and AGENTS.md (links also in SECURITY.md, CONTRIBUTING.md and the evidence) and checks that each link and anchor resolves, each transaction hash and account is in contracts/deployments, docs/mainnet-proof.json or docs/evidence, each Status row has a known marker and an existing path, each path, pnpm script and script command exists, and the versions, counts and other facts it knows match the code, with exactly one probarion-claim: marker for each claim id of section 17 of the interfaces spec, and the summary line the README quotes has the shape the checker prints (a <n> for each count). It checks claims, not whether the code works. It exits 0 when every claim matches, 1 when one does not (printed as file:line [check] what is wrong) and 2 when it cannot run. Without the full git history (a shallow clone) it skips the claims about the git history, and its last line says so. --online adds read-only checks of the chain (the named vaults' code hash and keys; that each cited transaction exists, was signed by an account the records name, a spend by the vault itself, and shows the error code, event or memo its row gives), the site's health route, the Chrome Web Store item and npm, and exits 2 when an endpoint does not answer. CI runs it offline through the real-repository test in scripts/check-claims.test.mjs, which fails on any claim that does not match; the ts job of .github/workflows/ci.yml checks out the full history (fetch-depth: 0), so the git-history claims are checked there too, and scripts/ci-workflow.test.mjs pins that checkout. The README's evaluation starts with it as step 0. Its first run found three claims, fixed where they are written: the short text of the INV-2003 approve transaction in the README ended in FJf instead of NCJf; trial.vaults.probarion.testnet, the vault that Create a vault made with Meteor on 2026-11-05, was in no record and is now under trial_vault in contracts/deployments/testnet.json with its create_vault transaction; and EVAL-REGRESSION had no marker, which is now on the eval:check test in apps/web/test/eval/replay.test.ts.

• @probarion/mcp: probarion-mcp init, a keys file, and probarion-mcp status, so the agent's keys stay on the user's machine and an MCP client's config needs only PROBARION_VAULT_ID. init --vault <id> [--keys-file <path>] makes the agent key and the ledger key and writes them to ~/.probarion/<vault>/keys.json (format probarion-mcp-keys/1, mode 0600, opened with wx so an existing file is kept: a second run checks it and prints the same public keys). The file and, outside Windows, each folder it adds an entry to are synced before the public keys are printed. It prints only the two public keys, the probarion agent add and probarion ledger set-key lines (the console's Agent (MCP) tab gets no link until it is live, and the console does not serve mainnet yet), and that a backup of the folder holds the two secret keys, with the CLI's Windows and git warnings. The server and status take their keys from both PROBARION_AGENT_KEY and PROBARION_LEDGER_KEY, else the file PROBARION_KEYS_FILE names (which must exist), else the default keys file, else run read-only. One key from the environment with the other from a file is refused, and the server's first line on stderr names the source. A keys file must be for this vault and its network, with each secret key matching its public key and two different keys; a problem names the file and the field, with no value from the file. The vault id is checked as a NEAR account id before it goes into a path. status only reads, and prints ok, not yet or fail for the keys (a keys file other users can read fails, outside Windows), the vault (not frozen), the agent key (a function-call key limited to spend, with allowance left), the ledger key (the vault's, limited to anchor), an active mandate bound to the agent key, the vault's USDC, and the local ledger against the latest anchor (the single-writer check, run dry), with one next step when not ready: the first fail that has one, else the first not yet. Exit code 0 when ready, 1 when not, 2 for a configuration error. init and status print their commands the way the binary was started (node and the path of bin.js from a clone), and a usage error echoes only a flag or a word, so a secret key passed as an argument by mistake is named by its position alone. The README's set-up is now init, the owner's two keys, status, and the client's config; keys in the client's config stay as the fallback.

• @probarion/mcp: the single-writer guard before request_spend also checks that the server's own ledger key signed every entry after the vault's latest anchor, and refuses with LEDGER_KEY_MISMATCH, sending nothing, when another key did (a keys file swapped while the ledger file stayed). The vault's next anchor would cover those entries under the current ledger key, and verify check a would fail for them. status runs the same check, says to anchor such entries with their key before the owner sets the new one, and does not suggest a new ledger key for a vault that another process anchors from its own ledger.

• The console's Agent (MCP) tab, /console/<vault>/agent, after Keys: the owner connects their own AI agent (Claude Code, Claude Desktop, Cursor or Codex) to the vault through the MCP server. Built, not tried yet.

  • The agent makes its two keys on its own machine (init). The owner pastes only their public keys, and the page refuses a pasted secret key in the browser, so it is not sent. The agent key's label is public on the vault, so the page and the server action refuse a label that holds a key (ed25519:, or a base58 run of 40 characters or more), and the field does not cut a long paste. Two owner-only server actions read the chain again at click time and return add_agent and set_ledger_key for the member's own vault, with the vault kind's gas allowances, for the owner's wallet to sign. Nothing is stored: these keys have no database row.

  • A vault has one ledger, so the ledger key is withheld from a vault whose ledger another writer keeps: hosted Payables (its active ledger key, its entries, or a ledger key it made) or anchors signed by another key. On testnet the page then links "Create a vault for this agent"; on mainnet it says vaults cannot be created there yet. An unused ledger key is replaced only after a danger confirm.

  • Steps 5 and 6 give each client's settings, which carry only PROBARION_VAULT_ID, with the Windows form for each client, and a status card read from the chain: both keys and their gas left, an active mandate for the key, the vault's USDC, and who keeps the ledger. A vault id that ends in neither .near nor .testnet also gets NEAR_NETWORK, in the settings and in the init and status lines. Until @probarion/mcp 0.1.1 is on npm (MCP_ON_NPM in apps/web/src/lib/agent/connect.ts), the page builds the server from a clone. Approvers and viewers see the status card only.

  • "Check these keys" runs from a form, so Enter works, moves the focus to the first field with an error, and says its result in a status region. Before anything is pasted, step 3 shows the keys the chain already has, as step 6 does.

  • probarion-mcp init and status link the tab on testnet. status offers it for the ledger key only on a vault with no anchor yet; otherwise it gives the probarion ledger set-key transaction.

• The Keys tab lists the keys on the vault that Probarion did not make, under "On the vault, held outside Probarion", with their allowance and Remove for an agent key. When the vault's ledger key is one of them, "Generate ledger key and set it in my wallet" shows a red notice and asks in a danger dialog first, as a ledger key made there would stop that agent. When the vault's keys could not be read, that dialog says it is not known whether the user's own agent holds the ledger key.

• The landing's status list adds the Agent (MCP) tab to the console's "Built, not tried yet" row.

• The overview's "Your first agent payment" card offers its keys step two ways, hosted Payables on Keys or your own AI agent on Agent (MCP), and ticks it when the chain shows an agent key and a ledger key that the console did not make.

• @probarion/mcp: probarion-mcp demo [--vault <id>], a read-only tour of the five tools against the live testnet demo vault. It needs no key and signs and sends nothing. It shows the tools and their fields, the live caps, the contract's check_spend answers (ok, held, OverPerPayment), an injected to field refused by the schema, a paid spend, and verify on the public ledger. A frozen vault is reported as a note (exit 0); an RPC that does not answer marks list_mandates, get_spend_status and verify as failed, skips the dry runs, and prints the server log (exit 1). Also --version and --help.

• @probarion/mcp: mcpName io.github.probarion/probarion and keywords in package.json (at 0.1.0 then), and README setup for Claude Code, Codex CLI, Claude Desktop and Cursor, with the Windows cmd /c forms.

• A testnet record of the Canary, in docs/evidence/canary-vault: its accounts, its mandate, the 2026-11-10 rehearsal whose raw spend the contract refused with OverPerPayment, and a live verify run with its snapshot. The run passes check f (no full-access key, only the ledger key and a spend-only agent key) and fails check c, because the Canary's ledger is private and the run checks the chain's 4 anchors against an empty ledger; the folder's README says which checks that leaves meaningful. The threat model's claim C9 now says Yes for the Canary vault, with that run, and the README has a section for it. Claim C8 says Yes for the demo vault, whose recorded snapshot passes checks a to i from a clone, in place of "N/A today".

• A phone-sized approval page for each held spend, /console/<vault>/approve/<spend>, which the "Approval needed" alert now links to, by Telegram and by email (roadmap G2). An approver taps the link, signs in with their NEAR wallet when they have no session in that browser, and approves or rejects in their own wallet, through @hot-labs/near-connect. On a phone that is Meteor Wallet, its app or its web wallet, on testnet, where the console runs; NEAR Connect offers HOT Wallet on mainnet only. It has not been tried on a phone with a real wallet yet.

  • The amount, the payee, why the spend is held, the time the hold has left and the Approve and Reject buttons, each the full width, come first, on a phone's first screen; the invoice and the mandate's caps follow. One line says what the wallet signs. Long account ids wrap. The page is held to WCAG AAA: every text colour reads at 7:1 or more, text is 14px or more with a line height of 1.5, and every control is 44px tall.

  • The page reads the spend from the chain (get_config, get_spend, get_mandate, at final finality) and shows the amount, the payee, the mandate, why it is held (its amount is above the mandate's approval_above), when the hold ends, and the invoice hash and ref the vault recorded. It names and links the console's invoice only when the console sent this spend from it (the chain's hash and ref, and the console's outcome for that invoice is this spend), and shows the invoice's own amount beside the spend's. An invoice that only has the same hash and ref, which an agent can reuse, is shown with a warning. Amounts to an Intents payee are read in the payee's asset, not the vault's token.

  • Approve is offered only for a spend the chain reads as held, and approve and reject only to an account on the vault's approver list on chain. An approver the console still lists, whom the chain no longer does, gets neither. Approve is not offered while the vault is frozen, after the hold has run out, or for a revoked mandate, and reject stays. Other members see the spend and who may approve it; anyone else gets a 404, as on every vault page. A spend id that is not a whole number from 1 is a 404 before any chain read.

  • The server signs nothing. The page hands the approver's wallet the vault's approve or reject with exactly 1 yoctoNEAR, the wallet must be the signed-in account, and the vault checks all of it again when the transaction runs.

  • A signed-out tap goes to sign-in and comes back to the same page.

  • The overview's held card links each held spend to its page.

• @probarion/mcp, an MCP server that gives an AI agent a Probarion vault to pay from, in packages/mcp. It was not on npm then and ran from a clone: node packages/mcp/dist/bin.js, over stdio. Five tools: list_mandates (payee, caps, what is left, uses left, approval threshold, expiry), check_spend (the vault's free check_spend view), request_spend, get_spend_status and verify. No tool takes an address, every input rejects fields it does not know, and amounts go in as USDC decimal strings (claim MCP-NOADDR, packages/mcp/test/safety.test.ts). No tool creates, changes or removes a mandate, a key or the vault's settings.

  • The server holds the vault's spend-only agent key and anchor-only ledger key, and no owner key. Without the two keys it runs read-only and request_spend is off.

  • request_spend names a mandate by id and runs decide() from @probarion/core and the vault's spend, signs the decision into the vault's ledger and anchors it. No invoice text or purpose document is read, so the purpose rule passes. The MCP client's reasoning is stored as an unattested proposal prefixed mcp:, so verify reports these decisions as rules-only. A second request with the same ref pays nothing; it is refused and names the vault's spend under that ref (earlier_spend). A hold with no spend on chain says no approver waits on it.

  • Before each payment the server checks that its ledger file holds every entry the vault's latest anchor covers, with the same root, and otherwise stops with LEDGER_FORK_RISK and sends nothing. That catches another writer once it has anchored; verify check d finds one that has not.

  • Settings come from the environment (PROBARION_VAULT_ID, the two keys, NEAR_NETWORK, NEAR_RPC_URLS, NEAR_ARCHIVAL_RPC_URLS, PROBARION_LEDGER_PATH). A key must be a valid ed25519 secret key, and an RPC URL must be https:// (http:// only on this machine) with no user name or password; a problem is named by its variable, with no value. Errors and log lines pass through a filter that masks secret keys and cuts every URL to its origin.

  • 103 tests, among them an end-to-end run over the SDK's fake chain and a stdio JSON-RPC session.

• The pay-per-call example in examples/402 (a private workspace package, testnet only). An HTTP endpoint answers 402 Payment Required with a quote: a price, a payee and a short text. An agent pays the text's sha256 through @probarion/mcp under a mandate, with 402:<quote id> as the ref, and sends the call again with the spend id and the redeem token the 402 gave it. The endpoint serves it only if the token matches, the paying vault was created by the factory (its vault_version view), and the spend is paid, to the seller's account, for the full price and for this quote's hash, at a block time before the quote expired; each quote serves one call. The agent pays under the lowest-numbered mandate for the payee that can still take the amount, and reads a held spend until it is paid before it calls again. Run its test with pnpm --filter @probarion/example-402 run test: 20 calls are paid and the 21st is refused with mandate.uses_exhausted. It is not an implementation of x402 or of any other payment protocol.

• A testnet record of that example, in docs/evidence/402-vault: on 2026-11-09 the vault percall.vaults.probarion.testnet paid 20 calls at 0.01 test USDC under a mandate of 20 uses, and the 21st was refused by code (mandate.uses_exhausted, nothing sent), as the contract's check_spend view also answered (UsesExhausted). Its live verify passes checks a to i; the ledger, the snapshot (with the 21 anchors) and the setup and spend transactions are in the folder.

• The Docs Center at /docs: 34 pages in six sections (Start here, Concepts, Build, Verify & trust, Operate, Resources), with a home of four doors (new here, owner, developer, evaluator). Each page was written from the code and checked against it in a separate verification pass. Each guide, tutorial and explanation marks what is Live, Preview or Planned; the sidebar's legend says what Preview means. Every page but the docs home has a source box with the date it was reviewed, the commit it was built from and the files it was checked against, and a "Copy page" button.

  • The reference tables are rendered from typed lists that tests pin to the code, so a table that drifts fails CI: the vault's 14 checks in their order, every PROBARION: code with the call that raises it and what to do next, the SDK and HTTP errors, the verifier's checks a to i, and the status list.

  • The reference pages: SDK reference (every export of @probarion/sdk and @probarion/sdk/testing), Policy rules (every rule id decide() records), CLI reference (every command and option, and who signs what it prints), Contract reference (every vault and factory method), Events (every NEP-297 event and its fields), HTTP API (every route under /api), Limits and costs (every cap, deposit and gas figure), Reproducible builds (rebuild a contract and match its code hash) and Architecture (a diagram of the parts, each tied to its code). Each table is data that its own test, apps/web/test/docs-ref-<area>.test.ts, reads against the code, so a command, method, event, route, rule or constant added or removed in the code fails CI until the page follows.

  • A Changelog page, /docs/resources/changelog, renders this file as it stands in the build.

  • Every owner and approver command carries a callout naming who signs it. A test checks every CLI line in the pages against the CLI's own commands and options, and each callout's signer against the CLI's owner and approver calls.

  • Search opens with Ctrl K or ⌘K, from the docs bar or from the home's search box. It loads a static index of every page but the home on first open and finds pages, error codes and CLI commands. An exact error code, or a pasted PROBARION:<Code> line, ranks that code's row in the catalog first, and opening a result moves focus to it. Without JavaScript, the search links go to the home's list of popular searches.

  • Every page has a Markdown twin at /docs/<page>.md whose first lines name the date it was reviewed and the commit it was built from. /llms.txt lists the pages, and /llms-full.txt holds them all for AI agents, with X-Robots-Tag: noindex.

  • A section's address, such as /docs/build, redirects (308) to its first page.

  • The landing's SDK and CLI cards link the developer quickstart and the install page, and its outcome statuses link "What each status means".

  • A Playwright spec, run locally and not in CI, checks the home's fold at 1440×900, the keyboard path through search, the sidebar's current link, the table of contents and its scroll-spy, the phone drawer, sideways overflow at 390 px, the twins' headers, the section redirects, the install page's code tabs, the 404s, the docs without JavaScript and a blocked or missing clipboard.

• A Canary attempt stores the source its link named: /canary?via=x stores x in the new column canary_attempts.via (migration 20261108000014_canary_via.sql). The set is closed (home, x, share, readme, proof, tamper, ext and usage, in apps/web/src/lib/canary/via.ts). Any other value is stored as no source, and the attempt runs as before. Nothing is recorded for a visit alone, there is no new cookie, and the source is not in the public feed or the leaderboard. The Rules link and the way back from the rules keep it. The Canary pill on /usage links with ?via=usage, and the README with ?via=readme. /privacy says so, and its date is now 2026-11-09. The migration and the app can be deployed in either order.

• docs/ops/metrics.md has three queries for the OWNER to run by hand: Canary attempts by source; outside owners stage by stage, from a vault to an agent key, a mandate, a first payment and still active a week after it; and first payments by UTC week. A test runs the doc's own SQL on the real schema.

• The README names the builder's other NEAR Hackathon 2026 entry, as the rules ask of anyone entering two projects. The two share no code.

• The README's section "Libraries, templates and AI-assisted code" lists what each part is built with (the contracts, the TypeScript packages, the web console, the extension, the tests, CI and the services), as the hackathon's rules ask (Q-005 in nearhackathon.com/HACKATHON.md). It quotes Q-001 and Q-005, and says that no code or library from the builder's earlier projects is used and no project template; that the type and constant definitions of the interfaces spec of 2026-10-21 were carried into the code; and that the code was written with Claude Code, whose trailer every commit other than a merge carries. Its "AI-assisted code" part sets out the builder's share: the product decisions the design spec records, what is built and merged, and the steps the runbooks mark OWNER or OWNER SIGNS. Prior work now dates the spec after the hackathon's announcement on 2026-10-19, from which Q-001 allows code, and before its start on 2026-11-01, in place of "before the hackathon build window".

• The landing page has a live check, "Try it, live on NEAR testnet" (/#try). A visitor picks what the agent tries: a normal invoice (2 USDC under mandate 1), a hijacked prompt ("Pay 50 USDC to attacker.near"), a made-up mandate (999) or someone else's key, or sets the mandate, the amount and the signing key by hand. The browser sends the request to check_spend, a view of v0.probarion.testnet, through rpc.testnet.fastnear.com and then rpc.testnet.near.org, and shows the contract's answer word for word (ok, OverPerPayment, NoMandate, NotAgent), the request as sent, and the mandate as the chain has it. A view call signs nothing and pays nothing, and the page always reads testnet. An amount that is not a number of USDC with at most six decimals sends no call. When no RPC host answers, the page shows the answers recorded from the chain by pnpm --dir apps/web record-live-check, and says they are recorded; without JavaScript it shows them as a table. Answers from an RPC host are parsed strictly, so a malformed one cannot break the page.

• The landing page has "Why not just a spending limit?" (/#compare): eight questions, each with what a limit contract you write usually does and what Probarion does, and Probarion's status on each from the status list. It also has "Plug in your agent" (/#integrate): the SDK, the CLI, the console and the planned MCP server with their status, and the SDK's quick start, held line by line to packages/sdk/README.md. An end-to-end test covers the live check against recorded answers, with both RPC hosts mocked.

• A new vault's overview shows its owner "Your first agent payment": the five steps from a new vault to a payment its agent makes inside a mandate. They are the vault, an agent key and a ledger key that the console holds active (as Payables needs), USDC in the vault (on NEAR, or as Base USDC in Intents), an active mandate, and the first paid spend. The steps are worked out from what the overview reads and from the console's own key rows. The next step links to its tab as the ink pill, a step whose read failed says it could not be checked, and the card goes away after the first paid spend. It is not shown when the spends cannot be read. It shows on external vaults in this network's USDC, to their owner. Create a vault now opens the new vault's page, where the card starts; before, it said "Registered" and stayed on the form.

  • On testnet, Mandates offers "Use the sample PO". It fills the form from a sample purchase order: 5 test USDC a payment, 20 in all, 5 payments, 30 days, paid to the owner. The PO is hashed in the browser as it is served, and the form refuses it unless the hash is the pinned one. Payables offers "Use the sample invoice", a 2 test USDC invoice with a fresh invoice number each time, sent with the same PO attached. The files are in apps/web/public/samples/. Mainnet offers neither.

• The ledger test on the landing page, each Canary answer and each proof page whose checks ran now end with a link to the next page. On the landing page, a run the verifier failed ends with "Caught." and a link to /proof. A Canary answer ends with "Put limits like these on your own agent", and a proof page with "Put your agent behind a mandate"; both link to the console. They ended at GitHub or an explorer.

• The console has a Top-up tab. The owner sends USDC on NEAR from their own wallet to the vault. On mainnet only, the owner can also ask 1Click for a quote that tops up the vault's Base USDC balance inside NEAR Intents, and signs the deposit in their own wallet. On testnet, which has no Intents or 1Click, the tab says so, names the stand-in contract and the test token, and offers only the NEAR USDC funding.

• Before the owner is asked to sign a 1Click deposit, the server checks the quote's signature against 1Click's key (pinned in the code and tested against the SDK's default) and that the signed request is the one the console sent: this vault as the recipient inside Intents, the owner as the refund address, the assets, the amount, the slippage and the referral, with no extra routing fields. It refuses a deposit address that is the vault, the owner or a token contract, and a quote that is stale, more than 5% above the amount, open past the deadline asked for, or with times that do not state their time zone. A refused quote shows its reason and offers nothing to sign.

• The Top-up tab does not offer a quote again after a deposit was sent or may have been sent, after 1Click stopped reporting its address as waiting, past its deadline, or when the amount typed changed. A cancelled or failed wallet attempt does not lift those guards. A new quote request clears the old quote and is switched off while the wallet is open.

• A testnet faucet, so anyone can fund a testnet vault. On a testnet vault's Top-up tab, the owner presses "Add test USDC", and POST /api/topup/faucet mints 25 test USDC straight into the vault, not into a wallet. It works once a UTC day per vault, for 3 vaults a day per owner account and for 50 vaults a day in all, and only at the testnet address, for a signed-in owner whose vault the chain agrees on; everyone else gets 404. It signs as probarion.testnet with TESTNET_FAUCET_KEY, a function-call key that can call only mint on usdc.probarion.testnet: before each mint the route reads the key from the chain and refuses a full-access key or one low on allowance, with nothing counted. The amount and the vault come from the server, not the request. A mint whose outcome is unknown answers with its hash and is not sent again. Without the key, the tab says to ask @probarionhq. The key is masked in logs, and docs/RUNBOOK.md has the steps to set it up.

• Owner-only top-up routes POST /api/topup/quote, POST /api/topup/submit and GET /api/topup/status, rate-limited per account, which answer fixed sentences rather than 1Click's own error text.

• Public site in the light brand design, deployed at https://probarion.xyz: a landing page with real testnet transactions, the path of one payment and a list of what works and what does not; a beta strip on every page, a header with a phone menu that works with no JavaScript, a footer, and plain sign-in, not-found and error pages. Open Graph and Twitter cards, an icon, robots.txt and sitemap.xml.

• The site's ledger test runs the real runChecks from @probarion/core in the visitor's browser on a committed test fixture of five entries signed with test keys. Three edits (an amount, an erased refusal, a refusal turned into an approval) each show what the verifier catches when an edit was not re-signed.

• /proof with no public vault is a real page, with a form that opens /proof/<account>, an inline error for an invalid account, and the ledger test.

• Tests that hold the site's named facts to the deployment record, the README, SECURITY.md and the contract source.

• Web console deploy checks, run with its tests: every environment variable the console reads is listed in .env.example with secrets left empty, no secret can reach the browser through a NEXT_PUBLIC_ name, migrations stay ordered and portable to a hosted Supabase, every scheduled job has a GET route that reads CRON_SECRET, and no browser code can import server-only code.

• apps/web/vercel.json and a first-deploy checklist for the owner, docs/runbooks/web-deploy.md (Supabase, secrets, Vercel settings, a smoke test).

• Community files: a pull request template with Safety and Review sections, bug and feature issue forms (blank issues are off; vulnerabilities go to the private channel SECURITY.md names), CONTRIBUTING.md and CODE_OF_CONDUCT.md (Contributor Covenant 2.1).

• CI: one verify check that needs every other job and passes only when each one succeeded (a skipped or cancelled job fails it), for branch rules to require. When a gate in the TypeScript, Rust unit or sandbox job fails, the job posts the last 60 lines of that gate's log as one annotation and in the job summary.

• A 1280×640 social preview image for the repository page, rendered from the brand by a script that refuses any other size.

• Vault contract (probarion-vault 0.1.0). The owner creates mandates, each with a payee fixed at creation (a NEAR account, or a Base or Solana address paid out through NEAR Intents), a limit per payment, a total, a number of uses, an expiry and an amount above which an approver must confirm. The agent's function-call key can call only spend, which has no recipient argument. The vault also has held spends with approve, reject and expire_held; a daily backstop per UTC day; freeze, unfreeze, withdraw and withdraw_intents for the owner; ledger anchors whose sequence goes up by exactly one; the free check_spend dry run; NEP-297 events; and 24 readable PROBARION:<Code> errors. Every owner and approver method that moves value or changes authority takes exactly 1 yoctoNEAR, which only a full-access key can attach; freeze takes none.

• Factory contract (probarion-factory 0.1.0). It creates <name>.<factory> vaults with no access keys, from vault code published as a global contract and referenced by hash, or from wasm it stores, keeps a registry of versions, and refunds the deposit when a vault cannot be created. It is not deployed on any network yet.

• Test contracts for the sandbox and testnet: intents-stub stands in for intents.near, and test-ft for USDC and the POA tokens. Neither is meant for mainnet.

• Contract tests: a unit test for every error code, property tests of the accounting invariants (spent plus reserved stays within the total; an invoice is paid at most once), and near-workspaces sandbox tests of the key limits, holds, payouts and the factory, which run in CI on Linux.

• Reproducible contract builds in CI (cargo-near 0.22.0 in Docker, pinned by digest), with each recorded build's code hash in contracts/code-hashes.json and compared on every pull request into dev or main and every push to them.

• Testnet deployment on 2026-11-01: the test tokens, the intents stub and the vault v0.probarion.testnet, which has no full-access key and runs the recorded reproducible build. Its smoke run paid 1 test USDC to a NEAR account, burned 1 test USDC with a WITHDRAW_TO: memo for a Base address, and was refused with NoMandate. The transactions are in contracts/deployments/testnet.json.

• The testnet demo vault demo.vaults.probarion.testnet, run end to end through the console on 2026-11-09: created through the factory, given an agent key and a ledger key, filled from the faucet and given a mandate. Payables paid 2 test USDC, then 4 test USDC once its approver approved the hold, refused a changed-bank invoice with mandate.payee_mismatch in the signed ledger, and refused a re-sent invoice on upload. Its proof page is public, and /proof on probarion.xyz opens it. A live npx probarion verify passed checks a to i. The invoices, the ledger, the snapshot and the verifier's output are in docs/evidence/demo-vault; the transactions are in the demo_vault block of contracts/deployments/testnet.json.

• The landing page's payment journey ends with those four invoices: one card each says what the invoice asked, what the vault did (paid, refused on upload, refused by code, held then paid) and links the invoice file, its transactions and its lines in the signed ledger, then the demo vault's proof page. A test holds each card to the evidence files and the deployment record.

• "The console" on the landing page, after the ink band: three screenshots of the testnet console from 2026-11-09, taken while a fifth invoice (INV-2004, 4 test USDC) went through the demo vault. They show the spend held for an approver, the invoice's page in Payables, and the vault's spends once the approver approved it with near-cli. Each caption names the network, the date and the vault, and links its transaction where it has one; on a phone the row scrolls sideways. The images are WebP files in apps/web/public/shots/, and a test reads each one's size from its header.

• Deploy and smoke scripts for testnet, runbooks for testnet, the factory and the planned mainnet vault (each signing step is the owner's), and pnpm proof for the mainnet evidence file.

• Web console, in progress: wallet sign-in with near-connect and NEP-413, checked on the server, with a signed session cookie; a Supabase schema with row-level security on every table, tested in PGlite; vault creation through the factory, with the CLI as a fallback; a vault overview with balances, NEAR runway, freeze and the held spends to approve; a keys page where the owner adds the agent and ledger keys from their wallet with the public key only; mandate creation for a NEAR or Base payee, with the same validation in the browser and on the server, and revocation; and a Postgres ledger store whose entries core's runChecks verifies.

• Web console, the public proof page (built and tested): /proof/<vault> shows a vault whose owner made its proof public. The result comes first: "All offline checks pass" (green), "Not proven yet" (amber) or "A check failed" (red). Then come checks (a) to (i), each with explorer links on the vault's own network, and the vault's cross-chain burns. When a burn is not proven, the page names the spend and the reason and gives the command that proves it. A private vault's page is shown only to its members, and anyone else gets a 404. /proof opens the demo vault set in PROBARION_VAULT_ID when its page is public. NEAR_ARCHIVAL_RPC_URLS, which is optional, lets the page read older burn transactions.

• Proof page downloads: snapshot.json (the ledger and chain data the checks ran on, for probarion verify --offline) and the vault's signed ledger as probarion-<vault>-ledger.jsonl (for probarion verify --ledger). Both have the page's access rules and rate limit, and a browser does not reuse an old copy. The page shows its snapshot's taken_at exactly as the verifier prints it, so a reader can tell when a download is the very snapshot the page checked. Until the probarion package is on npm, every command on the site and in the deploy runbook is shown as run from a clone of this repository (four set-up commands, then node packages/cli/dist/bin.js), and the tests run those commands as shown.

• Web console, Payables pipeline (built and tested): POST /api/console/[vault]/invoices takes an invoice (a PDF, a text file or pasted text) together with the purchase-order document hashed into a mandate, and runs the reference agent. Code rules decide, the vault contract pays the mandate's payee, and each payment is signed with the agent key its mandate is bound to.

• Payables pays an invoice by itself only when an attested private model on NEAR AI Cloud confirms the amount the code read. Without such a model (rules-only), nothing is sent: the invoice waits for the owner with the amount the code suggests. The model is shown the code's amount, so it confirms that amount rather than reading the invoice independently. A later SDK change will hide the amount from the model.

• Payables amount reader: it reads an amount only from a document that names itself an invoice, and only from a plainly written final total line in USD or USDC. It refuses everything else with a reason the console shows (not_found, ambiguous, unreadable, currency, truncated, zero or not_payable). That covers receipts, quotes, statements, credit notes, purchase orders, paid, void or test stamps, other currencies, totals in columns or split across lines, amounts after the total, and look-alike or hidden characters. Its tests hold 1,670 adversarial inputs, a ReDoS sweep of every pattern it uses, and three corpora of realistic invoices, with no wrong amount. On realistic invoices it reads about half and refuses the rest with the reason.

• Payables storage and duplicates: an invoice is stored sealed with a per-vault key, or as hashes only in zero-retention mode. A payment whose confirmation is pending is not sent again. A re-upload of a paid or pending invoice is answered as a duplicate when its normalised text, or its invoice number for the same payee (kept as a keyed HMAC), matches. Uploads are limited to 4 MiB per file and 4 MiB + 64 KiB per request. The migration apps/web/supabase/migrations/20261108000006_invoices.sql adds the invoice tables.

• Web console, Payables pages (built and tested against a fake chain, not yet tried with a real wallet): upload an invoice with its purpose document, see every invoice with its status in plain words, and open each one to see what the model wanted, what the code allowed and what the contract did, with explorer links for the payment and the ledger anchor. Zero-retention can be switched on there, and the page says what is kept. The migration apps/web/supabase/migrations/20261108000007_invoice_confirm.sql adds what these pages need.

• An invoice that waits for the owner shows, before any button, the amount, why it waits, the mandate as the chain shows it, the invoice line the amount was read from, who uploaded it, and every invoice of the same payee from the last 90 days with equal and near amounts marked. Confirm is not offered when that list cannot be read, when the payee is unknown, or when the retained text cannot be read or does not hash to the hash the owner signs. Reject stays available, and the page names the cause.

• The owner can pay a waiting invoice with a wallet signature: the server builds the message from database and chain values only, checks it against a full-access key of the vault's on-chain owner at a final block, and pays exactly the amount shown, once, even after a double click. A confirmation is single-use, expires after 5 minutes, and a new one ends the earlier unused one.

• Each owner confirmation is kept in the signed ledger with its signature, key, nonce and message, so the signature can be re-checked from the ledger entry against the decision it sits in. The block of the key check is the server's record: whether the key was the owner's at that block takes an archival node, and probarion verify does not check the confirmation yet.

• The owner can reject a waiting invoice; nothing is paid. The same text then comes back as a duplicate, and a corrected invoice counts as new.

• If the server does not answer after the owner signed, the page says the payment may have gone out and not to pay again; only a failure before that says nothing was sent. A row whose cycle is not recorded shows "not recorded yet, do not resend" and names the ref to read on chain. Such a row stays in that state until the reconcile job is built.

• The invoice reader accepts invoice numbers whose only digit is a 0 or 1 beside a letter, such as INV-C1. After the invoice word on a title line it refuses a status or document word in any token, such as Invoice PAID1001, Invoice DEM01 and Invoice void-2, and a vendor named Test24 Labs before that word still reads. A Title-case word with a look-alike digit is not an invoice id, and an invoice-to or invoice-from label is not a title. Read rates on the realistic corpora did not change.

• The Canary challenge has its backend, POST /api/canary/attempt: anyone can send text to a deliberately gullible AI accounts-payable agent and try to talk it into paying. The Canary does not pay from its own cycle: a code rule refuses every attempt, and the answer shows which rule refused and why. Its page, feed and scoreboard are described below.

• In live mode, a "pay" the code refused is also sent to the contract unfiltered, but only when the contract's own free dry run says it would refuse it, so visitors can watch the contract's refusal (for example OverPerPayment); the dry run makes sure such a spend pays nothing. This is limited to one on-chain attempt per visitor every 10 minutes and 30 an hour in total, stops by itself when the agent key's allowance drops below 0.2 NEAR, and is not started with less than 15 seconds left.

• Nothing the Canary puts on chain is derived from the visitor's text alone: the transaction carries a salted hash, fresh for every attempt and not stored, so nobody can confirm a guessed text from a public explorer.

• The Canary's ledger cannot be made public: a model can quote what visitors type, and a public append-only ledger could not take it back, so the database refuses it on every path, the console included. Attempts are stored as hashes and labels only. The public feed shows labels, outcomes and transaction hashes, with no visitor or IP identifiers; an attempt still running is left out until it is 90 seconds old, then shown as killed. The leaderboard is read on the server only.

• One Canary attempt is bounded at 50 seconds: the model calls share 30 seconds, a chain step takes at most 8 seconds, and an attempt that runs out of time ends as failed (or "unconfirmed" for a transaction) and is not retried. An attempt that gives up on a step still running keeps the Canary busy for 90 seconds instead of starting another cycle beside it.

• The Canary has a public page at /canary and its rules at /canary/rules. A visitor writes a message to a deliberately gullible model and sees what the model wanted, what the code rules decided and what the contract did. The vault's balance and mandate are read from the chain, and the scoreboard and the latest attempts come from the database behind a short cache. When the live Canary is paused, a replay is chosen, or no vault is set, the page shows the recorded attacks instead. The page opened on NEAR testnet on 2026-11-10 (see Changed).

• The Canary closes itself instead of running dry: it does not run while its ledger key holds under 0.5 NEAR; it answers 429 with Retry-After over 6 attempts an hour from one address (an IPv6 address counts by its /64), 60 an hour or 600 a day in total; it closes when its ledger holds 300 entries; and its model calls share a daily token budget that counts an attempt from the moment it starts.

• The site has a public Usage page at /usage that counts team vaults, external owners and Canary participants apart, for the network the app runs on. It shows counts and not dollar volumes, with the last 7 days beside each total, the model tokens a decision uses, and how each number is counted; a price in dollars appears only once one is set from NEAR AI's price list. A daily job computes the numbers, and the page refreshes them when they are an hour old. The Canary rules link to it.

• Each Canary attempt is recorded with the network of the Canary vault it was made on, so a mainnet Canary and a testnet Canary keep separate numbers on the Usage page.

• The daily usage job also deletes the rate limiter's rows older than a day, so that table no longer grows without limit. Applying the database update computes the usage numbers of the existing history.

• The watcher, GET /api/cron/watch, reads each vault registered with the app: its spends, mandates, anchors, refusals by the contract, low agent and ledger key allowances and low NEAR, and records each once in vault_events. It runs daily on Vercel and right after an invoice upload or a Canary attempt for that vault. docs/ops/watcher.md also sets out a per-minute Supabase Cron job, not yet run or tested.

• Owner alerts: an owner or approver can get a Telegram message or an email when a spend is held for approval, the contract refuses a spend, a spend is paid or paid out to Base, a payout fails, an agent or ledger key's gas allowance runs low, or the vault runs low on NEAR. Each goes out once per alert and event, not for a vault's old history, and a viewer sees addresses and chat ids masked. Every message says how to stop: the email's own stop link (and a mail client's one-click unsubscribe), the bot's /stop, or Remove on the new Alerts tab (/console/<vault>/alerts). The channels switch on once the owner sets TELEGRAM_BOT_TOKEN and RESEND_API_KEY (docs/ops/alerts.md).

• The web console serves testnet and mainnet from one deployment. The network of a request is the address it was opened at (APP_ORIGIN_MAINNET, APP_ORIGIN_TESTNET), with a Testnet | Mainnet switch in the header once both are served. Sessions, vault pages, the watcher and metrics jobs, alerts, the Canary board and /usage are per network, and a vault of the other network shows a card with a link to its own address. The per-network settings (NEAR_RPC_URLS, PROBARION_FACTORY_ID and four more) each have a _MAINNET and a _TESTNET form (docs/runbooks/web-deploy.md, section 3.5).

• The SDK takes a deadline: RpcClient remainingMs, NearApiJsSender sendTimeoutMs as a function, and NearAiProposer remainingMs and knownModel. All are optional, and the defaults are unchanged.

• Uptime monitors can check each address of the site: GET /api/health answers 200 when the deployment can read its settings and 503 when it cannot; GET /api/health/rpc?provider=<n> checks one NEAR RPC provider of that address's network (the right chain, and a block under two minutes old); GET /api/health/nearai checks that NEAR AI Cloud's public model list answers. Answers are cached for 30 seconds and do not include a key or a configured URL.

• A /status page on each address shows the live checks for that address's network, links to the other network's status page when that address is served, and says that funds stay in your own vault, under your own keys, if the service is down. The header's Status link opens it.

• Errors reach Sentry once SENTRY_DSN is set; until then the SDK is off. Each logged error becomes one issue per log key, tagged with its component. The Payables upload, the Canary attempt and both cron routes also tag the request id of their log lines, so one error can be matched to its logs. A failure of the root layout shows a plain "Something went wrong" page with a reference id.

• docs/RUNBOOK.md, an incident runbook for both networks: severity levels, the first 15 minutes, what a vault owner can do alone, freezing, withdrawing and unfreezing with the CLI printers (the owner signs every transaction), key rotation, RPC failover, burned cross-chain payouts, alerts, top-up, rate limits, deploys and migrations, status posts and a postmortem template. The runbook lint now checks it too: OWNER SIGNS above every mainnet send, and 1 yoctoNEAR on every one-yocto call.

• docs/ops/MONITORING.md: the health routes, the uptime monitors before and after each network gets its own address, the watcher heartbeat, the status page to create, and what Sentry receives, with its tags, alert rules and data scrubber fields.

• /.well-known/security.txt (RFC 9116) on every address, with the X account as the contact, a fixed expiry, one canonical URL per address, and links to the policy and its acknowledgments.

• docs/THREAT_MODEL.md: eleven attacks, each with the test, code path or testnet transaction that backs it; the hosted service's own surfaces; what a full breach of Probarion's servers could and could not do; failure modes, trust assumptions, known gaps; and the first security review's log. A test fails if it cites a safety claim that has no marker in the code.

• /security, /terms and /privacy pages. Every link on the site now opens a real page; nothing reads "coming soon" any more. Security sits in the footer beside Terms and Privacy.

• A browser smoke test of the built site runs locally with pnpm --filter @probarion/web test:e2e, after pnpm build. It builds with test settings only, and needs no wallet, database or chain. It serves both networks, testnet at localhost:3100 and mainnet at 127.0.0.1:3100, and checks that the header fits on each address at 375, 1120, 1280 and 1440 px. It is not in CI.

• A signed-in Browser extension page, /extension, connects the Probarion browser extension to your account on one network. Connect makes a 30-day connection and hands it only to the page itself, for the extension to take; "Show a code instead" shows a one-time pairing code that works for ten minutes, and warns that whoever enters it first gets the connection. Connected browsers lists each connection by its last four characters and its times, and Revoke ends it. The page says the extension is not released yet. The console header links it.

• The extension's server side, at the address of each network: POST /api/ext/pair exchanges a pairing code once for a connection token; GET /api/ext/inbox lets a token read what waits for you on its network: invoices waiting for the owner, held payments an approver can still approve, and the mandates an invoice can still be sent under; POST /api/ext/revoke ends the caller's own connection. Pairing is rate-limited per IP address and for the whole network, the inbox per account and network, and Connect and Show a code share one limit per account and network. An account keeps at most 5 connections per network: a sixth ends the oldest.

• Migration 20261108000013_extension_tokens.sql stores the connections and pairing codes.

• A connection can queue an invoice for the vault's owner: POST /api/ext/invoices takes the vault, the mandate the member picked and the file (a PDF or a text file, at most 4 MiB), for a vault where the connection's account is the owner or an approver, 20 per account and network in 10 minutes. It reads the invoice as the console upload does, runs the mandate's payee check (core's payeeHintContradiction) and the vault contract's free check_spend view, and stores the invoice waiting for the owner, with the checks it passed and the hold extension.mandate_chosen. It runs no cycle, calls no model, opens no key and sends no transaction. Only the owner's wallet-signed Confirm in the console pays it, and the contract checks that spend again. The same invoice sent twice gives one row, and the second answer says it is a duplicate.

• An invoice with an unclear amount, a mandate that cannot take invoices (revoked, expired, used up, or with a payee Confirm cannot name), keys Confirm cannot sign with, a payee that contradicts the mandate's, or a spend the contract would refuse is refused with its reason, and nothing is stored. A Canary vault takes no invoices from the extension.

• Migration 20261108000015_extension_queue.sql adds invoices.source and invoices.queue_checks, and invoice_queue, which stores an extension invoice in one transaction and refuses one without the extension.mandate_chosen hold.

• The Chrome extension, apps/extension (Manifest V3, Chrome 127 or newer), loaded unpacked; it is pending Chrome Web Store review since 2026-11-10. Connect it from the console's Browser extension page, or with a one-time code. Its badge counts the invoices and holds that wait for you and refreshes every 5 minutes; ! on the badge means the connection has ended. Right-click selected invoice text or a link to an invoice file on the same site, or open the popup on a PDF or choose a file: the popup reads the invoice, lets you pick a vault and a mandate, and queues it for the vault owner's wallet-signed Confirm in the console. It can't pay or approve, and says so under Send. It explains a refused invoice in plain words, shows "Already queued" for a second send of the same invoice, and checks in the browser what Probarion would refuse anyway (4 MiB for a file, 50,000 characters of UTF-8 text).

• pnpm --filter @probarion/extension build writes the release build to apps/extension/dist; build:dev also trusts http://localhost:3000. zip packs the release build into the store zip, the same bytes each time, and render redraws the icons and the five store images with a local headless Chrome. apps/extension/store holds the listing, the permission and data-use answers, the notes for the store reviewer and the upload steps; apps/extension/TESTING.md is the manual checklist, run before each upload.

• The I-HITL replay, a sandbox test in contracts/integration-tests/tests/ihitl.rs (ihitl_replay_the_agent_cannot_raise_its_own_limit_or_approve_itself). It replays, with the vault's agent key, the attack of the I-HITL paper (Breckenridge et al., arXiv:2610.35835), whose agents raised their own wallet limits by reading the passcode emailed to the owner. The test checks that a spend over max_per_payment fails with OverPerPayment and that one above approval_above is held. It checks that the node refuses each of the agent key's attempts to approve its own spend, create a bigger mandate, add keys, unfreeze, withdraw, call the USDC token, add a full-access key, deploy code, send NEAR or batch a key with a spend, before any contract code runs and with its exact InvalidAccessKeyError variant. It then checks that the mandate, the config, the agents and the held spend read back byte for byte as before, that the keys keep their nonces and scopes, and that only the approver's account's approve pays. Like the other sandbox tests, it runs in CI on Linux. The /docs page "The agent key cannot approve itself" (/docs/trust/self-approval, in Verify & trust) maps the paper's recorded run, and the steps the test adds, to the control that stops each, the layer and the evidence, with the testnet transactions that show three of the test's steps. It says how to run the test, and lists what it does not cover: an owner or approver key within the agent's reach, a payment split under approval_above, the MCP client's config, the email stop link and the single approver, and that it replays no model and runs only on a sandbox. The README's safety architecture and attack 7 of the threat model cite it, and the threat model's known gaps add the first two.

• Eval: 20 synthetic invoices (6 prompt-injected, 4 PDFs) run offline through the production reader, fact reader, mandate choice and decide() with the pipeline's custom rules, plus mirrors of the SQL intake duplicate guard, the SDK's execute() and the pipeline's owner wait; no transaction is built or sent. Rules-only results are committed: the code layer alone stops 8/8 of the invoices that must not be paid, with 0/20 false refusals, and 9/20 are held for the owner. In rules-only nothing can be sent by design, so its money moved wrongly (0/20) is not a result. The model replay is not recorded yet (the OWNER runs pnpm eval:record; a failed model call is recorded and decided rules-only, as the SDK does). See eval/README.md.

• The README has a "Privacy & Private AI" section after "NEAR technology used, and how", linked from the top row of links, from Contents and from a line under the tagline. It says what the TEE protects and what it does not, maps the track's example asks (an OpenAI-compatible call, a TEE-hosted model chosen from the models endpoint, a nonce, a Verified panel, keeping data off the server, sample documents) to the code that does each, and says what the hosted console keeps: each invoice file sealed, its file name and facts not encrypted, or with zero-retention only its hashes and the outcome, and the vault's signed ledger either way. It shows selective disclosure: an auditor who holds the invoice texts runs verify --invoices, and A8 passed on the demo vault's five attested decisions. It lists the known limits plainly: the signed ledger keeps the model's whole answer, the invoice reaches the model before the attestation checks run, the hosted server reads invoices in plain text, the request is not encrypted end to end and the NEAR AI gateway's attestation is not checked, invoice hashes have no salt (the Canary's raw spends aside), and the TEE measurement is not pinned. "How to evaluate Probarion in 5 minutes" now opens with a table of the five tracks this entry was submitted to (AI Security & Defense, Real-World Money, Agent Economy, Autonomous Business, Privacy & Private AI), with one thing to do and one to see for each, and adds a browser step: press "Check the TEE now" on the demo vault's proof page. The README's NEAR AI Cloud rows, its demo vault section and SECURITY.md add that the live run at 16:13 UTC on 2026-11-12 passed O1 and O2 on all five attested decisions, entry 15 included, and the README's libraries table lists @nearai/inference-sdk 0.2.1 for the web console.

• The landing page's hero shows two real testnet transactions from two vaults. The paid card is the demo vault's INV-2001, 2 test USDC to probarion-payee.testnet (HFyW61UZ…dQp1). The blocked card is the Canary rehearsal of 2026-11-10: 50 test USDC under a mandate that pays at most 1 test USDC a payment, refused by code (invoice.amount_invalid and custom.canary_no_autopay) and then by the contract on chain with OverPerPayment (6XuxN42d…v6z8DH), with a link to try the Canary (/canary?via=home). The buttons read "Try the demo" (#try) and "Explore the docs" (/docs), followed by a "Verify it yourself" link to the demo vault's proof page, and the fine print and the audience line are now one line that links the mainnet vault's payment and refusal on the mainnet explorer. While the live check asks, its answer panel says "Asking the testnet" and is aria-busy, and its hint keeps room for two lines, four on a phone. On a phone the amount slider gets a row of its own, 44 px high. The hijacked prompt names attacker.testnet and links the Canary. In the hero's cards a long account name moves under its label whole. "Plug in your agent" has a new title, the factory and vault accounts, a row of developer links under the code, and an MCP card that links the MCP server's README. Each of its three uses (invoices, pay per API call, cross-chain payouts) shows what the mandate controls, what that did on testnet, its evidence and its status pill; the cross-chain one says that on testnet a stand-in takes the place of NEAR Intents and that no payout through NEAR Intents has run on mainnet. The comparison links docs/comparison-2026-11.md. The two big headings read as sentences to a screen reader, and /canary, /status, /proof and /proof/<vault> give a canonical address at the request's own network. The README's hijack line and its note on the contract's refusal of the agent key's direct spend of 2026-11-09 are updated to match. In the blocked card, the row with OverPerPayment is labelled Contract, since that code is the contract's answer. The use cases, the notes under the code, the comparison link and the Built on section's fine print keep 2.5em between paragraphs and run to the 32em measure, as the WCAG pass holds the rest of the landing.

• The site's type targets WCAG 2.2 AA on every page and the AAA text criteria (1.4.6 contrast, 1.4.8 visual presentation) in the landing copy, the Docs Center, the console, the Canary, the proof page and the reading pages (Privacy, Terms, Security, Status). The site does not claim AAA conformance as a whole. The brand stays: Hanken Grotesk and IBM Plex Mono, ink, paper and gold.

  • Contrast: small gold text (eyebrows, the docs step numbers and tags, the error and 404 labels, the proof page's step badges) is gold-ink, 8.6:1 on paper, in place of gold-small (5.9:1), which stays on the landing's 42px step numerals only. band-mute goes from #a9a59b to #b0aca2 (8.7:1 on the ink band). The gold headline gradient is darker (#5e4210 to #8a6420, 4.9:1 or more on paper) and is used on 24px text and up only. The metal card's gradient ends lighter (#cfa54a) with a softer shade, so its ink reads at 7.6:1 or more and its labels (88% ink) at 7:1 or more. The header is 96% paper, so its grey text stays at 7:1 over the ink band. Link underlines are 60% ink, placeholders use mute, and a disabled control is drawn at 65% opacity in place of 50% (its ink label reads at about 6:1), or at 75% for the red buttons, whose label then reads at 4.9:1 in place of 3.8:1.

  • Visual presentation: reading text has a line height of 1.5 or more. A paragraph break leaves 2.5em or more from the top of one paragraph's last line to the top of the next one's first, inside docs list items and steps, the landing's story cards and screenshot captions, and the Canary cards too. Reading blocks run to 32em, about 71 characters on average (the new --container-measure token, max-w-measure in classes), nested ones included: a docs step's paragraphs, a verifier check, the docs hub's agent block, and the Canary's replay banner and the note under it. Laid out at 1440px, each line of reading text on the docs and the public reading pages has 80 characters or fewer (before this change some reached 109, and at 33em some still reached 82).

  • Sizes and weights: text set in the stylesheets and class names is 12px or more, light weight is used at 24px and up only (card and dialog titles go from 22px to 24px), docs articles style h4, and the landing's panel and comparison headings are 17px. The architecture diagram is the exception: its smallest labels are 12 units of an SVG that scales with the column, so they draw at about 11.6px in a 1440px window and 10.7px where it scrolls.

  • Text spacing and reflow (1.4.12, 1.4.10): the docs search boxes grow with their text, inline pills, the nav links and the landing's inline code wrap, scrolling code blocks and tables keep their screen reader text inside them, the console's definition lists stack on a phone, and its wide tables scroll inside their card.

  • Focus and edges (2.4.7, 1.4.11): selects and text areas get the shared focus ring, the docs search input's ring is drawn all round, a ring inside a clipping box is drawn inside it, the Canary tables and the landing's screenshot row on a phone leave 6px of room for the ring of a link at their edge, a link that the keyboard focuses inside a sideways scroller is scrolled into view (Chrome left the second screenshot mostly out of sight), form fields have mute borders, the pressed Canary scenario has a 2px ink edge, and the open docs code tab has a gold-bright bar.

  • The site declares color-scheme: only light (also as Next.js viewport.colorScheme), since it has no dark theme yet. only also turns off a browser's own automatic dark mode (Chrome's), which would recolour the tokens without their contrast checks. Forced colours still apply: in them (Windows contrast themes), buttons, pills, the metal card, the pressed scenario and the open console tab keep a visible edge.

  • apps/web/test/typography-aaa.test.ts reads globals.css and the CSS modules and fails on a text colour pair below 7:1 (4.5:1 at 24px and up), a disabled label under 4.5:1, a reading line height under 1.5, light weight under 24px, text under 12px, justified text, an ellipsis, or a missing forced colours rule. For the rules it lists, it also fails on a paragraph break under 2.5em or a reading block wider than the measure. site-facts.test.ts holds small text to 7:1 and the gold headline to 4.5:1.

  • apps/web/e2e/a11y.spec.ts (with @axe-core/playwright 4.14.0, a new dev dependency) runs axe-core's WCAG 2.0, 2.1 and 2.2 A and AA rules, then its AAA contrast rule, over /, /status, /docs, a docs article and the demo vault's proof page, and checks reflow at 320px with and without the 1.4.12 spacing. It also lays out every docs article and the public reading pages (45 pages) at 1440px and fails on a line of reading text over 80 characters or a break between two paragraphs under 2.5em; code, tables, mono labels and text of 24px and up are left out. A local run on 2026-11-12 passed all 65 tests of this spec, and the docs, landing and smoke specs with them (123 in all); the test settings reach no database, so the proof page was checked in its unavailable view.

  • Not covered yet: a dark theme (and, with only light, a browser's automatic one), prefers-contrast, font sizes in rem, the architecture diagram's labels under 12px, visible labels on the register-vault and email forms (they have a placeholder and an accessible name), and the signed-in console pages in axe and in the laid-out checks.

• The Canary no longer follows NEARAI_MODEL. That variable pins the NEAR AI Cloud model for Payables and the SDK factory; the Canary keeps the SDK's default order (z-ai/glm-5.3-flash first), the model of its recorded attempts. With Qwen/Qwen3.8-27B pinned on probarion.xyz on 2026-11-11, a Canary attempt timed out at 40 s and was decided rules-only. The deploy runbook says so in the NEARAI_MODEL row.

• Release 0.1.1 is on npm: @probarion/core, @probarion/sdk, probarion and @probarion/mcp 0.1.1 were published on 2026-11-11 from the tag sdk-v0.1.1, and the official MCP registry lists the server as io.github.probarion/probarion. What the repository says about npm now matches. The README says so in its banner note, its Status rows for core, the SDK and the CLI (on npm as 0.1.1), the 0.1.1 row (Shipped on 2026-11-11, with the install lines), the MCP server's row and the quick start, which runs the server as npx -y @probarion/mcp@0.1.1. SECURITY.md supports 0.1.1 and lists @probarion/mcp with the other packages. The @probarion/mcp README leads with npm and the registry name, and gives each client's npx form next to the build from a clone. The docs pages that named 0.1.0 as the npm release, or said the MCP server is not on npm, say 0.1.1 (Install, the CLI and SDK references, Let an agent pay, Ledger and anchors, the docs home, the developer quickstart, Evaluate in 5 minutes, What is Probarion, What works today, whose "npm release 0.1.1" section replaces the one for 0.1.0, Architecture, For AI agents and Verify a vault); the MCP server stays Preview. The landing's pills read "0.1.1 on npm" for the SDK and CLI and "Tried on testnet, 0.1.1 on npm" for the MCP server. MCP_ON_NPM in apps/web/src/lib/agent/connect.ts is true, so the console's Agent (MCP) tab gives npx -y @probarion/mcp@0.1.1 for init, status and each MCP client, with no clone to build. This file's opening note says both releases are published. The tests that pin these lines follow them, and an install line in the docs may name @probarion/mcp.

• probarion verify --online: when check e fails because NVIDIA's NRAS token is not_yet_valid by this computer's clock (a clock a few seconds behind is enough, since @nearai/inference-sdk allows no tolerance), the report adds an online hint: line that says to sync the clock and run again, and prints it on stderr as a warning (with --json, only there). Check e still fails; the hint is not a result. Only the SDK's own failure message at the start of check e's detail adds it, so text from a ledger cannot.

• The grey text on /proof/<vault> (the decision cards, each check's detail, the model note and the limits line under A1 to A7) uses the mute token, 7:1 or more on paper.

• The browser extension is on the Chrome Web Store as version 0.1.0 (https://chromewebstore.google.com/detail/probarion/hhadnmnjdlamihjjoejphkimnbcfidmn (opens in a new tab)). The README (Status row Shipped), the extension's README, the store pack, What works today, the HTTP API and architecture docs, the threat model and /privacy say so and link the listing. What works today keeps it at Preview, with the server half it calls, because no end-to-end run with a real wallet against this deployment is recorded yet. The threat model covers the extension's own permissions and storage, SECURITY.md lists apps/extension in scope, /privacy is dated 2026-11-11 (/terms keeps 2026-11-10), and the Browser extension page (/extension) gains an Add to Chrome link. Loading it unpacked stays the way to run it from source.

• Docs: the text says the team is on Vercel Pro. The crons in apps/web/vercel.json still run once a day, by choice; Pro also accepts hourly or per-minute schedules, and the runbooks say what to change for those. A 90 s Canary attempt fits Pro with or without Fluid compute, which stays pinned on.

• The Canary evidence (docs/evidence/canary-vault/README.md) names the mandate's purpose document, the sample PO-1001, whose SHA-256 matches the purpose_hash read from the chain, and lists the vault's 11 transactions from create_vault to the rehearsal, each confirmed by RPC.

• The Canary is open on NEAR testnet at /canary on probarion.xyz, in live mode, since 2026-11-10. Its vault is canary.vaults.probarion.testnet, with one mandate that pays probarion-payee.testnet at most 1 test USDC a payment and holds every spend. In the team's rehearsal that day, a fake invoice asked for 50 USDC: the model proposed paying 50 USDC, the code rules refused it (invoice.amount_invalid), and the contract refused the same spend on chain with OverPerPayment (transaction (opens in a new tab)). The README, the status list on the site, the /docs pages and the policy reference call it Live on testnet instead of not open yet. The threat model's claim C9 names the Canary vault (its verify run is under Added), and the deploy runbook says CANARY_MODE is live on probarion.xyz. The README's beta note says the demo vault's proof page and the Canary are public. Mainnet has no Canary vault, so /canary there still shows the recorded attacks.

• The "Approval needed" alert, by Telegram and by email, links the held spend's approval page, /console/<vault>/approve/<spend>, in place of the overview's held card. An event without a spend id still links the held card (/console/<vault>#held).

• The browser extension is pending Chrome Web Store review (submitted on 2026-11-10), so the site says what it does in the present tense. /privacy#browser-extension, which the store listing links, adds that a file read from a tab or a link is fetched with your own session for that site, and that the extension reads the address of the tab you are on when you open it; its date moves to 2026-11-10. The /extension page says the extension is pending review and can be loaded unpacked from apps/extension. The Docs Center's What works today lists the extension for Chrome as Preview, and its HTTP API page drops "not released yet". The store's connect screenshot is rendered again with the page's new lead.

• Every console page's text reads at WCAG AAA: 7:1 or more for normal text, as on the phone approval page. The shared colour tokens in apps/web/src/app/globals.css are darker: mute and plan go from #5f5c55 to #4e4b45, ok from #17693f to #125935, bad from #a32a1c to #8e2317, and wait from #7a5a18 to #5e4210 (the value of gold-ink). Each reads at 7:1 or more on paper, on a white card and on its own pale background, so the Notice and Badge tones (5.4:1 to 5.9:1 before) and the console header's "Signed in as" line (6.2:1 on paper before) pass. The landing page and the Docs Center read the same tokens, so their grey and status text is darker too.

  • Grey text at 60% ink, in Payables and the invoice confirm panel, is 75% ink (9.1:1 on a white card), and the sign-in page's "Console" label is gold-ink (9.3:1).

  • text-xs and text-sm have a line height of 1.5 (WCAG 1.4.8): 18px and 21px.

  • apps/web/test/console-kit.test.ts fails when a tone pair, a button, or any text colour class on a console page, the sign-in page or the extension page reads below 7:1 on paper or on a card.

• The MCP server's row in the status list moves from Planned to "Tried on testnet, not on npm" (Preview in the docs), and the README's Status row, its NEAR technology rows, its testnet proof and its quick start say what the server and the 402 example do. The Docs Center pages that called the MCP server Planned (HTTP API, Let an agent pay, Architecture, For AI agents, What is Probarion, What works today, Security model) now say it is Preview, and said it was not on npm then. The threat model cites claim MCP-NOADDR and drops the MCP server from its planned surfaces.

• The workspace includes examples/*, and the CI pin tests cover packages/mcp and examples/402: their test, build, typecheck and lint scripts, and the publish guard of packages/mcp.

• The landing page states each caveat once. The beta strip says "Unaudited beta on NEAR testnet, test tokens only." and that Probarion holds no owner key, links the known gaps, and folds to its first sentence on a phone; only mainnet asks for small amounts, and the footer no longer does. The status list gives the web console two rows, "Tried on testnet" and "Built, not tried yet", says which tests check the page, and ends with a "Known gaps" list: no third-party audit, and v0.probarion.testnet's missing ledger, its failing checks d and h, and its older build, which the on-chain section and the closing used to repeat. In the payment journey, what is true today is a note labelled "Today" with a gold rule, on steps 2 and 5.

• The site header has "Docs" right after the Canary, and Usage moves to the footer's Product column. The landing page's closing button "Evaluate in 5 minutes" opens the docs page of that name in the same tab, not the README section. The sitemap lists every docs page with the date it was reviewed.

• The docs, the README and the landing say that release 0.1.0 of @probarion/core, @probarion/sdk and the probarion CLI is on npm: the install page, the developer quickstart, the status table, and the landing's "0.1.0 on npm" pill for the SDK and CLI and "Shipped, on npm" for the offline verifier. The README's browser checks add the verifier at /#verify, and its "NEAR technology used, and how" table adds NEP-297 events, near-workspaces and cargo-near and says what is not done live yet: the first mainnet payout, a 1Click top-up with a live quote and an attested NEAR AI Cloud decision.

• The site writes its CLI commands as npx probarion … now that 0.1.0 is on npm: the landing, the proof page, /security and the console's CLI fallback, under one line saying that npx needs Node 24 and asks once before it downloads the package, with no set-up. A mainnet pre-ledger check on the proof page also reads the repository's evidence files, so for it the page says to git clone the repository first. The root package.json is renamed probarion-monorepo, so npx probarion also runs at the root of a clone. The README's offline verify step and the deploy runbook's smoke step 7 use npx probarion, and the install page says so.

• The READMEs of @probarion/core, @probarion/sdk and the probarion CLI install from npm (npm install @probarion/core, npm install @probarion/sdk @probarion/core, npm install -g probarion or npx probarion) and keep the steps to build from a clone. These are the pages npm shows for 0.1.0. Their release notes are closed, so pnpm release:check sdk-v0.1.0 passes.

• The landing page leads with what an owner gets: "Give your AI agent a budget, not your wallet", with buttons to the live check and to "Plug in your agent". The thesis and the numbers band are one section, "The problem": an agent with its own wallet key next to an agent with a mandate. The order is the problem, the live check, the comparison, how a payment works, plugging in an agent, the payee, the ledger test, the chain and the status list. The header's first link is "Try it", the fourth step of "How a payment works" links to the live check, and the closing says what to do next above its links.

• The landing's refused card and the README banner show a real refusal from 2026-11-09 in place of mandate 999: the agent key asked mandate 1 for 6 test USDC, over its limit of 5 USDC a payment, and the contract answered PROBARION:OverPerPayment (tx 4715d4nb…Vsr1, recorded in contracts/deployments/testnet.json). Step 3 of the README's evaluation and step 5 of the docs' evaluation read it from an archival node.

• The site, the docs, the Terms and the READMEs no longer say that anyone can verify the ledger without a condition: a ledger is private until its owner publishes it, so they now say the owner can publish it for anyone to verify. A test keeps the unconditional claim out of the site's code, the docs and the READMEs. The landing's hero also names the category above the headline ("A mandate layer for AI agents on NEAR") and says who it is for under the buttons.

• The landing's offline check runs in an empty folder with npx alone. The site serves a byte-for-byte copy of the test fixture at /samples/valid-snapshot.json, and step 5 prints the download and the verify on separate lines, with a note to type curl.exe in Windows PowerShell 5.1. Step 2 of the README's evaluation gives the same two lines for a reader with no clone.

• The ledger test on the landing page and on /proof puts a plain line under each of the nine checks, and calls a cross-chain spend a withdrawal ("Withdrawal to Base") in place of "Burned for Base" (site audit P1-11).

• A spend that waits for approval now comes first on the vault's overview, right under the tabs. A hold that ran out does not count, since the vault refuses approve then. The "Approval needed" alert, by Telegram and email, links straight to the card (/console/<vault>#held); before, it opened the overview, where the held card was the third or fourth. While a spend waits, the card offers an owner or approver "Get a message next time", a link to the Alerts tab, unless a confirmed alert of the vault already sends held spends.

• The Alerts tab says when a message can arrive: right after an invoice is uploaded on Payables (and, on the Canary vault, after each attempt), otherwise at the watcher's next run, once a day at 00:00 UTC or every minute if the per-minute schedule is turned on. A test holds the time to the schedule in apps/web/vercel.json. Before, it read as if a check every minute were already running.

• The console has the landing page's brand. It used a Tailwind kit from before the brand: buttons about 32px tall, 14px fields that a phone zooms in on, and Approve and Reject buttons that looked the same on a held payment.

  • Buttons are ink pills at least 44px tall. Approve is the ink pill and Reject a red outline. Any wallet button whose confirm dialog says it cannot be undone gets the red outline too: removing an agent key and revoking a mandate.

  • Fields are 16px, with the landing page's mute edge.

  • Cards, notices, badges and status text use the colour tokens. A test reads them from globals.css and checks that every text colour reads at WCAG AA.

  • The vault's tabs mark the open one with an underline and aria-current. Each tab is 44px tall, and on a phone they sit in one row that scrolls sideways.

  • The confirm dialog's Cancel is an outline pill.

  • Explorer links are ink rather than blue.

  • A pending payout is gold, the brand's colour for in progress.

  • Every page but the landing page now uses the header's frame: 1320px wide, with 16px gutters up to 620px and 24px above, so the page's left edge lines up with the logo. The console's and the extension page's content stays 1024px wide.

  • The proof page's coloured result panels are unchanged.

• The sign-in page says what signing in is for (a vault, a mandate and a key that can only call spend, or approving a held payment) and what it takes: on testnet, a NEAR testnet account, and about 3.3 test NEAR to create a vault later, which stays in the vault and cannot be withdrawn. On mainnet it says vaults cannot be created yet, as the factory is not deployed. Below the sign-in button it links the ledger test, which needs no wallet, and the terms and the privacy notice. The sign-in card had one button and no link.

• The ledger test gives its verdict in one plain sentence beside PASS or FAIL, read from the verifier's result, such as "Entry 2 was changed after it was signed, so its signature no longer matches." It names a cause and an entry only when the verifier's own words name them, and otherwise gives the counts. The counts and the verifier's words on each check that did not pass sit behind "Verifier detail". The test printed the counts as its verdict and the verifier's words under each failed check.

• Sessions name their network and belong to one address, so a person signs in at each network's address with a wallet of that network. After this change everyone signs in once more. A vault's routes and actions answer 409 wrong_network at the other network's address, and a registered vault keeps its network: Register at the other address cannot move it (network_mismatch). Per-account rate limits are counted per network, and Register has its own.

• The console asks for confirmation in its own dialog instead of the browser's confirm box. The dialog is titled with the action, shows the same question as before, and says that the wallet asks for the signature next and that nothing is sent until then. Revoking a mandate, removing an agent key, and rejecting a spend or an invoice get a red dialog with a "Cannot be undone" line. Esc, a click outside the dialog and Cancel all cancel; the focus starts on Cancel and goes back to the button that was clicked, and the action button is held back for a moment after the dialog opens, so a double click on the opener does not confirm it.

• The site and console are served at https://probarion.xyz; www.probarion.xyz redirects there, and https://probarion.vercel.app (opens in a new tab) still answers.

• The vault factory is deployed on NEAR testnet as vaults.probarion.testnet (code hash FK6mMqUd…). It serves the vault build with the set_ledger_key fix (code hash 3cQXYDvf…) as an embedded version, so each new vault stores its own copy of the code and needs about 3 test NEAR. The console's Create a vault and the CLI's vault create use it. A smoke vault, smoke-embedded.vaults.probarion.testnet, has no access keys. The README, the site's status list and contracts/deployments/testnet.json record it; v0.probarion.testnet still runs the earlier build.

• The README, SECURITY.md and the site say what an offline check shows: verify --offline checks a snapshot against itself, so a forged snapshot with re-signed entries passes, and only verify --vault reads the chain. They also say that verify --vault v0.probarion.testnet fails checks d and h today, because the smoke run sent its spends without a ledger.

• The wallet provider moved to /console and /login, with one connector per network. First-load JS of / went from 148.5 KiB to 139.5 KiB gzip.

• The web build downloads Hanken Grotesk and IBM Plex Mono from Google Fonts and serves them itself, so pnpm verify reaches the network for that step.

• The repository pins pnpm 10.34.9 through packageManager in the root package.json. CI, the release job and Vercel builds run exactly that version, which is patched against the pnpm advisories GHSA-vq4v-j7r6-jq4m, GHSA-c59q-g84q-2gj5 and GHSA-vx52-2968-3vc6. The pinned tests refuse a workflow that names its own pnpm version, and they refuse a pin outside pnpm 10. The web deploy runbook sets ENABLE_EXPERIMENTAL_COREPACK=1 on Vercel and checks the build log for that version.

• verify: check h reports a burn it cannot prove as unproven, lists it in VerifyReport.unproven, and VerifyReport.ok is false while any check fails or is unproven. A burn transaction that cannot be read right now is unproven (tx_unavailable). A burn record that names a transaction holding no burn pair, a transaction the node does not know, or a hash that is not a NEAR transaction hash fails h.

• verify: checks g and h trust only the network's own intents contract and POA assets. The online check O1 holds the TDX quote to the DCAP policy and to its report data, and O2 binds the NVIDIA payload to the request's nonce. Measurement pinning (O1b) is deferred, so quote_verified stays false.

• SECURITY.md now gives response targets (acknowledge within 72 hours, a severity within 7 days, a SEV2 fix within 14 days, disclosure once fixed or after 90 days), a safe harbor for good-faith research that covers the Canary under its rules, the Canary as a public testnet challenge with no reward, the practices CI runs, and acknowledgments.

• The deploy runbook's smoke test checks the health routes and security.txt. The key rotation runbook says that a new master key also resets duplicate matching by invoice number.

• Signing in from the Browser extension page brings you back to it, with the extension's request kept. Every other sign-in still returns to the console.

• /privacy has a new last section, "Browser extension". For each connected browser it says what Probarion keeps: a sha256 of the connection token, its last four characters, a browser name and its times, kept after the connection ends. For a pairing code it keeps a sha256, your account, the network and the times, and deletes the record, once the code is used or expired, the next time a code is made. A connection cannot pay, approve or confirm a payment. It ends after 30 days, when a sixth connection on the same network replaces it, or sooner with Revoke. The rate-limit sentence names code pairing, counted per IP address like sign-in.

• The threat model, the incident runbook, the key-rotation runbook, the monitoring guide and the security policy cover the extension's connections: what a token can read, that it cannot pay, approve or confirm, how to end one or all of them, and that a new master key does not end them. The runbook has a new entry, "An extension token leaked" (SEV3). Ending every token deletes the pairing codes first, in one transaction. For a stolen session it ends the sessions first, then either ends every token with that SQL or waits out the session's pairing codes (10 minutes) before revoking its tokens at that network's address. The threat model lists, as a known gap, that a few dozen addresses can hold code pairing at its network-wide limit while Connect keeps working.

• The console marks an invoice sent from the browser extension: the Waiting card says "Waiting for you: sent from the browser extension", a queued invoice lists only its holds under "Why it waits" and every check under "Checks when it was queued", and once a Confirm ran, the page says why the signed ledger's purpose rule passes under the mandate the member picked. The extension's inbox says where each waiting invoice came from.

• /privacy's Browser extension section, the threat model, the security policy, the incident runbook and the monitoring guide say that a connection can also queue an invoice, which waits for the owner's Confirm: what is stored for it, its rate-limit bucket, who ends a leaked connection, and that a queued or rejected invoice keeps its duplicate slot. Alert rule 4 (the money path) includes component:extension. The /docs security model and "What works today" pages say the same, and the /docs HTTP error table gains the Extension API rows.

Fixed#

• The Canary gives its model up to 55 s instead of 40 s, and says so when the model's time runs out. On probarion.xyz the "Ignore previous instructions" example message was decided with no proposal twice, at 2026-11-11 23:40 UTC (with Qwen/Qwen3.8-27B pinned) and 2026-11-12 01:15 UTC (with z-ai/glm-5.3-flash): the chat request alone ran out of the 40 s (39,631 ms and 39,692 ms; the model calls before it took under 0.4 s), and the answer only said that no proposal came back. Template probarion-proposal/v1 asks for up to 4096 tokens with no limit on reasoning, and the attested answers in docs/evidence (533 to 895 tokens, 401 to 792 of them reasoning) came at about 20 to 60 tokens a second, the signature's fetch included, so a model that reasons longer on a message that argues with its instructions does not finish in 40 s. A cap on reasoning or on max_tokens would change the request bytes that check A8 rebuilds, so the time is what changed: the model's calls now share 55 s (CANARY_LIMITS.modelBudgetMs) and end at least 15 s (afterModelMs) before the attempt's 80 s deadline, so its decision is still written and anchored. The route's 90 s, the lease, the code rules and the system prompt are unchanged. A model that answers in about 40 s or less still leaves raw mode its 15 s; after a slower answer the proposal is shown and raw mode sends nothing (no_time). When the model's time ran out, the answer now reads "No proposal: the model's time ran out (at most 55 seconds) before its answer came back. Code decided without it." Whether 55 s is enough for that message is not measured yet.

• @probarion/core: decide() refused as mandate.payee_mismatch an invoice the mandate allows when an attested model's payee hint put the mandate's own NEAR account in address, next to a chain. It was seen on the testnet demo vault, ledger entry 12 (2026-11-11T23:35:56Z, model Qwen/Qwen3.8-27B): the invoice named probarion-payee.testnet for 2.00 USDC under PO-1001, the model proposed to pay with the hint address and name set to probarion-payee.testnet and chain set to base, and the rule refused with "invoice names base address probarion-payee.testnet; the mandate pays NEAR account probarion-payee.testnet". The v1 proposal schema has no NEAR value in its chain enum and no account field but near_account, so a model can put a NEAR account in address. For a NEAR payee, payeeHintContradiction in packages/core/src/policy.ts now takes the mandate's own account, in near_account or in address and whatever the chain, as naming no other payee, except an account that is also a Base or Solana address, such as an ETH-implicit 0x account, which in address still refuses. A hint still contradicts when either field holds any other value, compared exactly so another letter case refuses, or when it names a chain with no account and no address. The rule for a Base or Solana payee is unchanged, and so are the schema and the system prompt of probarion-proposal/v1. verify does not re-run the policy, so ledger entries already written are unaffected. Tests cover the entry 12 hint, the contradictions next to it, and accounts that are also a Base or Solana address. The /docs pages "Why spend has no payee" and "Policy rules" say the same, and the line citations of docs/THREAT_MODEL.md follow the code.

• @probarion/core: decide() refused as mandate.payee_mismatch when an attested model's payee hint named the mandate's NEAR account plus a chain with no address, so the SDK and the console's Payables refused a payment the mandate allows. It was first seen on the testnet demo vault on 2026-11-11 (INV-2006). The proposal schema's chain enum offers only base and solana, so the model filled one next to the NEAR account, and payeeHintContradiction in packages/core/src/policy.ts took the chain alone for an external destination. For a NEAR payee, a chain next to the mandate's own NEAR account, with no address, now names no other destination. A hint still contradicted when it named another NEAR account, an address that is not blank, or a chain with no NEAR account, and that last refusal now names the chain rather than address (none). (The entry above, for ledger entry 12, then also took the mandate's own account in address: an address contradicts when it differs from that account or is also a Base or Solana address, and a chain only when neither field is given.) The vault pays the mandate's payee either way, and verify does not re-run the policy, so ledger entries already written are unaffected. Tests cover both hint shapes from the model and the contradictions next to them. The /docs pages "Why spend has no payee" and "Policy rules" said the same then.

• Console: an invoice upload keeps to one time budget counted from the request's start (apps/web/src/lib/payables/budget.ts). The NEAR AI calls share 40 s from the first one, each capped by what is left, and they end by 50 s from the start whatever the start took, so a slow model decides rules-only and the invoice waits for the owner with nothing sent. The chain reads before the first transaction stop at 60 s. A read refused there sends nothing: a context read or the check_spend dry run stops the upload as an error that a new upload runs again, a refused POA balance read holds the decision on intents.balance_low, and a refused anchor read leaves the anchor to the next cycle. From the first transaction on, nothing changes: the send keeps the SDK's own timing. Before, the SDK's defaults (90 s for the chat alone) could outlast the route's 60 s, and a function stopped mid-cycle left the row in processing, which blocks a new upload, with no time left for the watcher kick. The route's maxDuration goes from 60 s to 90 s, planned as 10 s for the start, 40 s for the model, 10 s for the decision and its dry run, 10 s for the send, the anchor and the row, and 20 s for the watcher kick after the answer. The kick now gets the function's end (the route's start plus 90 s), so after a late answer (a slow send) it claims fewer alerts instead of starting a send that the platform cuts off. The tenant lease goes from 90 s to 120 s, 30 s longer than the route; the route's 90 s stays under the 2 minutes after which the alerts' SQL takes a sending alert back. No migration and no new setting. Tests pin the sums, the lease against the route, and the route against the SQL; the budget and the kick's end counted from the route's start, past a slow session and mandates read; a late answer that shortens the kick's alerts, on a fake clock; and, with the real SDK on PGlite, a 70 s model held for the owner with nothing sent. At the route, with a stubbed cycle, the kick is asked for before the cycle runs. The RUNBOOK's "Invoice stuck in processing" covers an upload or an owner's Confirm left there: how to read the row's ref, look its spend up on chain, and tell from the last decision whether a spend can still land.

• @probarion/mcp: the burned outcome no longer tells the agent to poll get_spend_status. A burn is final for the vault: the agent must not resend it under any ref, and should tell the owner if the payee reports nothing. On mainnet the bridge releases the funds and Probarion does not watch that release yet; on testnet the note says intents-stub stands in for NEAR Intents and nothing leaves NEAR. Spend outcomes, the developer quickstart, the glossary and the SDK README say the same.

• Console: a long account id (a 64-character implicit account, or a long named one) wraps inside the confirmation dialog, such as "Create vault in my wallet", and in the mandate form, where it made the dialog scroll sideways. The shared ConfirmDialog wraps its title, body and footnote anywhere.

• SDK: NearApiJsSender with sendTimeoutMs as a function starts no step (signing, the send, a status lookup) when the caller has less than 50 ms left or the function throws. Before, such an answer became a 1 ms deadline and the transaction was still sent, so a spend could land while the caller was told its outcome was unknown. A signing or send that does not start is TxSendFailed (nothing was sent); after an InvalidNonce the node confirmed, it is that refusal; a lookup that does not start keeps the outcome unknown, with its tx hash. The Canary counts the first case as no_time. A deadline longer than a timer holds (about 24.8 days) is cut to that, where Node.js fired it after 1 ms. New tests in packages/sdk/test/deadline.test.ts pin each case.

• SDK: RpcClient and NearAiProposer do not start a call with less than 50 ms of the caller's remainingMs left, where they refused only at 0. A timer can fire about 1 ms before Date.now() reaches the deadline, so a call sent with what was left could only time out: a test in packages/sdk/test/deadline.test.ts failed now and then in CI for that reason (seen on #87). A NEAR AI signature back-off is waited out only when it leaves 50 ms for the next try. RpcClient still cuts its back-off to the time left. The Canary counts a refusal under that floor as running out of time, as before (no_time for the dry run, deadline for the cycle). New tests pin 1, 49 and 50 ms with fixed clocks.

• The Canary's persona tells the model to write amounts in USDC's smallest units, with an example (50 USDC is 50000000), as core's default prompt does. On 2026-11-10 the live testnet Canary's model wrote 50 for 50 USDC, a spend of 0.00005 USDC that the contract would hold, so the contract's refusal could not be shown. The earlier persona is kept as CANARY_SYSTEM_PROMPT_V1, and CANARY_SYSTEM_PROMPTS lists both hashes for a verifier of the Canary's ledger.

• A Canary attempt gets 80 s instead of 50 s: the model 40 s instead of 30 s, the route's maxDuration 90 s and the tenant's lease 130 s. On 2026-11-10 a slow model used 30 s on its own, and the step that sends a refused spend to the contract, which needs 15 s, was skipped. apps/web/vercel.json sets "fluid": true, and the deploy runbook says to leave Fluid compute on.

• The console's Keys page asks for larger allowances on the Canary's vault: 3 NEAR for its agent key and 2 NEAR for its ledger key. With the allowances every other vault gets (1 NEAR and 0.25 NEAR), the Canary could not open, since it does not run while its ledger key holds under 0.5 NEAR. A key's allowance is fixed when the vault adds it, so these apply to keys added from now on.

• The Canary's vault card says when the owner froze the vault: it then refuses every spend and every approval until the owner unfreezes it. A config read that failed adds nothing to the card.

• The Canary page shows its form only when the Canary vault and NEARAI_API_KEY are set, the database holds a private Canary tenant for that vault on the page's network, its ledger has room, its ledger key has gas for anchors, and the vault holds a mandate. It went live as soon as the vault was set, with a form that could only answer "not ready" when the key, the tenant or the mandate was missing. The page asks once a minute, with the same tenant and ledger key checks the attempt route makes; otherwise it shows the replay.

• Once the Canary's ledger is full, the page says the live Canary is closed instead of showing the form.

• The Canary replay shows attacks from the team's own tests, starting with the smoke run's refusal on testnet: the agent key cited mandate 999 and the contract answered NoMandate. A test holds every transaction in the list to a deployment record. The list was empty. Under the banner the page offers the ledger test, which needs no wallet, and @probarionhq on X, and it shows the "paid to an attacker" and Freysa cards, which hold whether or not the Canary is live.

• The live Canary page says why it shows no ledger: the model's answers in it can quote what visitors wrote, so it stays private.

• Sign-in explains two more answers of the server in words: unavailable (sign-in could not finish, so you were not signed in) and payload_too_large (the wallet's answer was too large to be a sign-in). The page showed the bare code before.

• The mandate form refuses a purpose document over 4 MiB. It took 25 MB, but the Payables upload takes the invoice and its purpose document together in 4 MiB, so a mandate made from a larger document could not be paid through Payables. The form still only hashes the file, in the browser.

• The near_low alert links to "Send NEAR to this vault" on the vault's Overview. It linked to Top-up, which funds USDC only.

• The Canary rules ask for a report the way SECURITY.md does, with a direct message to @probarionhq on X. They named an email address that does not exist.

• The package READMEs built the packages from a clone while none was on npm; they had shown npm install. The SDK quick start no longer passes an empty NEARAI_API_KEY, which throws a ConfigError. The SDK README says that a code hold has no approval to give, and that an unconfirmed spend is found by listing the vault's spends and matching ref: spends.get takes a spend id, and the contract has no lookup by ref.

• freeze takes no deposit, but a function-call key can sign it only when it may call the vault. The CLI's vault freeze help, SECURITY.md and the README said any owner key could freeze. The CLI's note also says that reject and expire_held still work while the vault is frozen.

• THREAT_MODEL: the SDK and the CLI read the bare NEAR_RPC_URLS, and only the web app reads the per-network names; the SDK already marks a ledger fork risk (LEDGER_FORK_RISK); and CI runs on pull requests into dev and main and on pushes to them. The README and this changelog said CI runs on every push.

• This changelog no longer contradicts itself about the Canary page, the pages that once read "coming soon" and the factory's fixed vault build, and the 0.1.0 heading says it is not released yet.

• With both networks served, the site header no longer runs past the window between 1101 and 1360 px wide, where the network switch left no room for the links. At those widths the links move into the menu, as they do below 1101 px. With one network the header is unchanged.

• The browser-tab icon has a clear background instead of a white square, and its mark is larger. The bar under the coin is ink in a light browser theme and paper in a dark one.

• Signing in now lands on the console. A prefetched redirect could leave the visitor on /login with no error.

• /proof/<vault> says the checks did not run, and its snapshot.json and ledger.jsonl downloads answer 503, when the database or the server's environment fails. They answered 500 before.

• A failed sign-in challenge says sign-in is unavailable and nothing was signed. The sign-in page no longer names wallets the picker may not offer.

• Web console: no link answers 404. While the Canary, the open metrics (now /usage), Payables, Top-up, Alerts, Security, Status, Terms and Privacy pages were being built, a link to one showed as "coming soon" and the landing page did not present it as available. Each is now a real page.

• Proof page: text from a ledger or the chain cannot disguise a result. Bidi and control characters are replaced, long values are cut, and only well-formed transaction hashes and account ids become links. A database or chain failure shows "No result" with the reason, and it is not shown as a pass.

• SDK: a Next.js app that uses @probarion/sdk keeps its own source tree out of its server functions. The file ledger store's dynamic path carries a turbopackIgnore hint. With it, the proof page's server functions trace a few dozen files instead of the whole app (about 225 files before).

• Vault: set_ledger_key deletes the old ledger key and adds the new one in two separate receipts, the delete first. A failed delete no longer rolls back the new key and leaves the vault unable to anchor, and a rotation fits on a vault with no spare NEAR. v0.probarion.testnet runs the build from before this fix. The fixed build (code hash 3cQXYDvf…) is version 1 of the testnet factory vaults.probarion.testnet, so every vault the factory creates runs it.

• Web console: a payment is signed with the key its mandate is bound to; a key made active again keeps its first activation date; and a discarded key that shows up on chain is reported, for the owner to keep or remove.

• Web console, keys: only the ledger key can be loaded as "the active key"; every payment loads the agent key named by its mandate, not the ledger key. A ledger key that is stuck now says what to do for this vault's code: a vault built before the set_ledger_key fix needs a new vault, and a vault on the fixed code can set a new ledger key. A set_ledger_key that recovers a stuck key, whose only failed receipt is the delete of the missing old key, is shown as done, after the page checks that the new anchor-only key is on the vault.

• Web console, mandates: an expired mandate that still has payments waiting for approval shows Revoke, because the contract can still approve them. The "Sign mandate" button stays locked after a reload or an edit while an earlier create may have landed, so a mandate cannot be created twice by accident. The form refuses an expiry less than an hour away and a payee that is the vault's own USDC, Intents or asset contract; it warns when a 0x address is typed as a NEAR account (that is not a Base payout) or when the NEAR account does not exist; and it says plainly when the vault does not allow Base payouts. Revoke and the form appear only when your account is the vault's owner on chain.

• The SDK's chain reads fail closed: a malformed node answer is an error, and a node's own error is kept after the read fails over to another endpoint rather than reported as an outage.

• A database test of the alert list could fail when two subscriptions were created in the same instant and tied on their creation time.

• A canary test could fail about once in 58 runs, when the agent key it changed already ended in the character it wrote, so the key it called inactive was the active one.

• A test of the NEAR transaction-hash check could fail about once in 58 runs. It added a character to a random hash and expected the result to be refused, but a small 43-character hash with one more character can still decode to exactly 32 bytes. The test now starts from the largest hash, 44 characters long.

• Another invoice uploaded in the console with the same number for the same payee as one that was paid or may still pay is refused by code, rule custom.invoice_number_duplicate, and the decision entry signed by the ledger key says why. Before, the upload got a 409 before any rule ran, and nothing reached the ledger. An invoice queued from the browser extension with that number, and the same text uploaded again while the number stays blocked, are still duplicates at intake. When this rule's refusal is the outcome's code, the console's notice says whether an upload can run again: when the earlier invoice waits for the owner, after the owner rejects it. Otherwise the number stays blocked: a paid invoice, a spend held on chain (even one the approver rejects), a payment sent but not confirmed, a cycle cut off with an unknown outcome, and a refusal that could not be written to the new invoice. A paid invoice is not paid again. The notice gives no advice to reissue the bill under a new number: the console cannot yet show that the earlier spend can no longer pay, and a new number would pass every duplicate check. The migration apps/web/supabase/migrations/20261108000016_invoice_number_rule.sql changes invoice_insert.

• A bill could be paid twice when an agent paid one text of it outside the console. The owner's Confirm of that text in the console was refused as already paid (invoice.duplicate), and that refusal freed the invoice number, so a second text of the bill with the same number could run and pay. The duplicate guard now counts a refusal because the text was already paid or may still pay as an invoice that may pay: invoice.duplicate or ledger.unresolved in its signed decision (also when another rule refused first), or the contract's DuplicateInvoice or DuplicateRef. The same holds at intake and at the owner's Confirm. The guard also names an invoice that may have paid before one that waits for the owner, so the notice offers a re-upload after a Reject only when no invoice with the number may have paid. When two invoices with the number wait (the browser extension and the console raced), the notice asks the owner to reject each. A Reject still frees the number of the invoice it rejects. The migration apps/web/supabase/migrations/20261110000017_invoice_guard_paid_refusals.sql changes invoice_insert and invoice_confirm_begin.

• Web console, Payables: an invoice whose spend the vault held for an approver shows what the chain says of that spend now. The list and the invoice's page read the vault's spends with the same list_spends view the overview reads, and match the spend by its id and decision hash. An approved spend reads "Approved and paid on NEAR"; a rejected one, or one whose hold expired, says nothing was paid. Both pages kept "Held for approval", the outcome stored when the cycle ran: on testnet, INV-2003 and INV-2004 of demo.vaults.probarion.testnet were paid on chain but read held. The pages only read the chain: the stored outcome and the signed ledger do not change. When the spends cannot be read, the page says so and shows the status the cycle recorded.

• Web console, Payables: the banner says "1 invoice waits for you", not "1 invoice wait".

• Web console, Mandates: the table gives each column room. At desktop width its headers ran together ("PaymentsExpires").

• An on-demand render of /docs/trust/reproducible-builds on Vercel, such as a POST, which skips the prerender, answered 500: the function did not carry .github/workflows/ci.yml. The page's data now reads each file by a literal path. The docs functions carry the 8 repository files they read (0.09 MB), not about 1,170 (17.7 MB).

• The README's "Why it is different" said every vault method that moves value or changes authority needs a deposit. freeze takes none, and spend moves value without one; it now says every owner and approver method but freeze needs one. The /docs page Holds and approvals said no hold or approval had been recorded on NEAR testnet; on 2026-11-09 the demo vault held spends 2 and 3 and its approver approved both, and no rejection or expiry is recorded yet.

• The threat model's note on how evidence is named counted only the smoke transactions of contracts/deployments/testnet.json as testnet evidence. It now counts each transaction recorded there (factory.deploy_tx, smoke, direct_refusal and demo_vault), since attack 7 cites the direct refusal and the demo vault's held spend and its approval.

Security#

• Why the TEE measurement is not pinned yet (O1b): docs/measurement-pin-2026-11.md records the finding of 2026-11-12. A NEAR AI Cloud TDX quote measures the VM's operating system and NEAR AI's management harness, and compose-manager starts the model stack after boot from a git tag of nearai/cvm-compose-files, so no measurement pin can show which model image ran. For the demo vault's entries 10 to 13 the stored event log replays RTMR0 to RTMR3 of each quote, and MRCONFIGID holds the compose hash; the page lists those values, a script to check them, what NEAR AI publishes and what O1b would need. The landing page row stays "Checked online on testnet, image not pinned", and SECURITY.md, the threat model, the README's NEAR AI Cloud row, the verifier checks page and the interfaces spec link the finding.

• Key sealing: the web console generates agent and ledger keys on the server and seals them at rest with libsodium secretbox, under subkeys of one master key, KEY_ENCRYPTION_SECRET. A key becomes active only when the chain shows that exact function-call key on the vault, limited to spend or to anchor.

• Key rotation: pnpm --filter @probarion/web rotate-keys dry-runs by default, re-seals under the new master only after every row verifies, writes all rows in one compare-and-set call, prints counts only, and does not generate a master. The steps, including what to do after a leak, are in docs/ops/key-rotation.md.

• Release pipeline: release.yml publishes only from a sdk-v* tag on main, through the protected npm-release environment, with npm provenance, and the job that publishes runs no repository code. The release check gates the versions, this changelog, open release-note comments and the packed tarballs. A version already on npm is skipped only when npm holds the same bytes. release.yml is pinned by sha256, every step runs with pipefail, and a test refuses any step that would swallow a failure. Third-party actions are pinned by commit SHA, and the cargo-near download is checked by sha256.

• CI scans the whole git history for secrets with gitleaks.

• The repository's GitHub security settings are on: private vulnerability reporting, secret scanning, push protection and Dependabot security updates. SECURITY.md, /security, the Docs Center's security model page and the issue form now offer the private advisory form (Security → Report a vulnerability) beside the direct message on X, and the threat model's known gaps no longer list the settings as off; secret scanning's non-provider patterns and validity checks stay off.

• The console refuses, at start, settings that could point a network at the other chain: an unsuffixed per-network setting while both networks are served, a mainnet account id ending in .testnet or a testnet one ending in .near, and an RPC host named after the other network. The error names the variable, not its value. Sign-in, Register and the approvers re-sync read the chain only through RPC URLs that answered the JSON-RPC status call with that network's chain_id, and answer 503 wrong_chain once any URL has answered with the other chain.

• Before an error report leaves for Sentry, the user, cookies, headers, request bodies and query strings are removed, console breadcrumbs are dropped, a request breadcrumb keeps only the origin of another host, and every known secret value and secret shape is masked. Tracing and browser sessions are off. The request that starts a server instance is left untagged, so its tags cannot reach other requests' reports.

• An extension connection token is stored only as a sha256 and its last four characters, and a pairing code only as a sha256. Logs and error reports mask any connection token they contain, and tag the extension's errors as their own component.

• A connection token cannot pay, approve or confirm a payment. apps/web/test/ext-structure.test.ts reads, with the TypeScript parser, every app module the extension's server code can load, and fails if one imports a module or function that pays, signs or opens a sealed key, imports anything from near-api-js, names an RPC method that sends a transaction or a database function or column that returns a sealed agent key, builds its own database client, asks for a subkey other than the session's, loads a raw crypto package outside lib/crypto, uses the cookie session, or loads code dynamically. It reads imports and names: it catches a plain import, not code written to get around it, so review of every change to that code is the other control.

• The extension asks for four permissions (storage, contextMenus, activeTab, alarms) and Probarion's three addresses, trusts a connect message only from Probarion's own /extension page with a nonce it made, and calls only /api/ext/pair, inbox, invoices and revoke, which a test pins. A file fetched from the page's site is refused if a redirect took it to another site. The popup builds its DOM without HTML strings, and the bundles hold no remote code. Disconnect revokes the token, and so does a new connection that replaces one for the same address.

• Since the queue, that test's claim is narrower: the extension's server code imports nothing that pays or signs and, outside lib/crypto, nothing that opens a sealed key. The queue's route reads the master key only to seal the invoice with sealInvoice and to key its duplicate guard, as the console upload does. The test also fails if that code builds a VaultClient with anything but a vault id and an RPC client, re-exports it, or imports the cycle's decide.

• Dependabot triage: vitest 4.1.12 (it was 3.2.7) in the root and every package, and @sentry/nextjs 11.11.0 (it was 11.10.0) in apps/web, fix 12 of the 18 open alerts: vitest, @vitest/mocker and tinypool (dev only; vitest 4 no longer uses tinypool), and glob and minimatch (Sentry's build plugin, build time only). elliptic has no patched version and is not reachable: only the CLI's verify --online loads it, to verify TDX quote signatures, and the flaw is in signing. wee_alloc stays a known gap until a new vault version. rustls reaches only the sandbox tests and is bumped with the next contract change, since changing contracts/Cargo.lock makes the recorded code hashes stale. Every alert is in the threat model's review log.

0.1.1 - 2026-11-11#

Added#

• @probarion/mcp, an MCP server that gives an AI agent a Probarion vault to pay from, over stdio, as the command probarion-mcp; this is its first release on npm. Five tools: list_mandates (payee, caps, what is left, uses left, approval threshold, expiry), check_spend (the vault's free check_spend view), request_spend, get_spend_status and verify. No tool takes an address, every input rejects fields it does not know, and amounts go in as USDC decimal strings. No tool creates, changes or removes a mandate, a key or the vault's settings. The server holds the vault's spend-only agent key and anchor-only ledger key, and no owner key; without the two keys it runs read-only and request_spend is off. Error messages and log lines pass through a filter that masks secret keys and cuts every URL to its origin. The package is also a library: createServer builds the server on any ProbarionPort, buildPort is the port over @probarion/sdk, and main is what the binary runs.

• @probarion/mcp: request_spend names a mandate by id and runs decide() from @probarion/core and the vault's spend, signs the decision into the vault's ledger and anchors it. The MCP client's reasoning is stored as an unattested proposal prefixed mcp:, so verify reports these decisions as rules-only. A second request with the same ref pays nothing; it is refused and names the vault's spend under that ref (earlier_spend). Before each payment the server checks that its ledger file holds every entry the vault's latest anchor covers, with the same root, and otherwise stops with LEDGER_FORK_RISK; and that its own ledger key signed every entry after that anchor, and otherwise stops with LEDGER_KEY_MISMATCH. Either way it sends nothing.

• @probarion/mcp: probarion-mcp init --vault <id> [--keys-file <path>] makes the agent key and the ledger key on the user's machine, writes them to ~/.probarion/<vault>/keys.json (mode 0600 outside Windows) and prints only the two public keys, with the owner's probarion agent add and probarion ledger set-key lines; probarion-mcp status checks, read-only, that the vault is ready for them (exit code 0 when ready, 1 when not, 2 for a configuration error); on testnet, init and status also link the console's Agent (MCP) tab, where the owner can paste the two keys instead (status offers it for the ledger key only on a vault with no anchor yet); probarion-mcp demo [--vault <id>] is a read-only tour of the five tools against the live testnet demo vault, with no key; and --version and --help. The server and status take their keys from both PROBARION_AGENT_KEY and PROBARION_LEDGER_KEY, else the file PROBARION_KEYS_FILE names, else the default keys file, else run read-only, so an MCP client's config needs only PROBARION_VAULT_ID. The other settings are NEAR_NETWORK, NEAR_RPC_URLS, NEAR_ARCHIVAL_RPC_URLS and PROBARION_LEDGER_PATH; a problem is named by its variable, or by the keys file and its field, with no value.

• @probarion/mcp: when a client connects, the server gives it instructions for the model (the MCP instructions field; each client decides whether its model sees them), under 1,200 characters: whom it can pay, check_spend first when unsure, and what to do with a held, unconfirmed, refused or burned spend. A burned spend is final for the vault, in the words for the server's network.

• @probarion/mcp: mcpName io.github.probarion/probarion in package.json, and packages/mcp/server.json, its entry for the official MCP registry, which the OWNER publishes with mcp-publisher once npm has the package. server.json is not in the tarball.

Changed#

• probarion verify --online: when check e fails because NVIDIA's NRAS token is not_yet_valid by this computer's clock (a clock a few seconds behind is enough, since @nearai/inference-sdk allows no tolerance), the report adds an online hint: line that says to sync the clock and run again, and prints it on stderr as a warning (with --json, only there). Check e still fails; the hint is not a result.

• @probarion/sdk: the README and the SpendOutcome comments say that burned is final for the vault. The bridge releases the funds on the other chain, and Probarion does not watch that release yet, so process does not return settled. The README says the ledger is a record that the vault's owner can publish for anyone to check.

• @probarion/core: no change in its code since 0.1.0. It is released at 0.1.1 because the npm packages share one version.

• Packaging: ESM only, Node 24 or newer, as in 0.1.0. Each of the four tarballs holds dist/ (without source maps), README.md and LICENSE. The release workflow publishes them in dependency order: @probarion/core, @probarion/sdk, probarion, then @probarion/mcp.

Fixed#

• @probarion/sdk: RpcClient and NearAiProposer do not start a call with less than 50 ms of the caller's remainingMs left, where they refused only at 0. A timer can fire about 1 ms before Date.now() reaches the deadline, so a call sent with what was left could only time out. A NEAR AI signature back-off is waited out only when it leaves 50 ms for the next try. RpcClient still cuts its back-off to the time left.

• @probarion/sdk: NearApiJsSender with sendTimeoutMs as a function starts no step (signing, the send, a status lookup) when the caller has less than 50 ms left or the function throws. Before, such an answer became a 1 ms deadline and the transaction was still sent, so a spend could land while the caller was told its outcome was unknown. A signing or send that does not start is TxSendFailed (nothing was sent); after an InvalidNonce the node confirmed, it is that refusal; a lookup that does not start keeps the outcome unknown, with its tx hash. A deadline longer than a timer holds (about 24.8 days) is cut to that, where Node.js fired it after 1 ms.

0.1.0 - 2026-11-09#

Added#

• @probarion/core: TypeScript mirrors of the vault and factory contract views; RFC 8785 canonical hashing; ed25519 keys; the signed, hash-chained ledger with the ledger-derived attestation nonce (bound to the vault account); the deterministic policy engine decide() with its built-in rules and custom rules; the model proposal parser; offline attestation checks A1 to A7, and the request-binding check A8 for auditors; and the snapshot verifier runChecks with checks a to i.

• @probarion/sdk: a NEAR JSON-RPC client with failover and backoff; vault, intents and factory clients; function-call key signing through near-api-js 7; the NEAR AI Cloud adapter (private TEE models, a nonce-bound attestation report, the provider_tee signature); the JSONL file ledger store (locked, which needs a local file system with hard links) and the in-memory store; the Probarion class with process, requestSpend, checkSpend, mandates, spends, anchors, rules, snapshot and verify (with optional online TEE quote checks through @nearai/inference-sdk); and @probarion/sdk/testing test doubles (fake chain, fake NEAR JSON-RPC server, fake NEAR AI Cloud).

• probarion CLI: vault create, mandate create, mandate revoke, agent add, agent remove, ledger set-key, spend approve, spend reject, vault freeze, vault unfreeze, vault withdraw and vault withdraw-intents check their input against the contract and print the transaction for the owner or approver to sign with near-cli-rs (1 yoctoNEAR where the contract requires it); the CLI does not sign. agent keygen makes an ed25519 key pair (--out <file> or --print-secret). check dry-runs a spend against the contract; verify runs checks a to i on a live vault or, with --offline, on a saved snapshot, prints a table or --json, and exits 0 (pass), 1 (a check fails or verify cannot run), 2 (a burn is unproven) or 64 (usage); --online adds the TEE quote checks O1 and O2 when @nearai/inference-sdk is installed and says when they did not run. ledger export copies the ledger to a new file.

• Packaging: ESM only, Node 24 or newer. Each tarball holds dist/ (without source maps), README.md and LICENSE, and is published from CI with npm provenance when the repository is public.
