No silent success, but a status that is affirmatively wrong. - -### What was observed - -With an attended session attached and working, the operator pressed **Detach -tab** in the side panel. The session then reported: - -```json -{"mode":"attended","status":"connected","browser":{...},"tabs":[{"tabId":2134210639,...}]} -``` - -while every command answered: - -```json -{"type":"action_result","ok":false,"error":"no active CDP session"} -``` - -So `status` said `connected`, `browser` was populated, and `tabs` still listed a -tab that was no longer under control. - -### Why it happens — two independent causes - -**1. The attended enum has no state for it.** `packages/protocol/src/index.ts:382`: - -```ts -export const AttendedSessionStatusSchema = strictObject({ - mode: z.literal("attended").optional(), - status: z.enum(["pending", "connected", "detached"]), -``` - -Three states, and the real machine has at least four: no socket; socket up with -no tab attached; socket up with a tab attached; socket gone. `connected` -currently covers the middle two, which are the two that differ in whether a -command can succeed. - -The unattended lifecycle in the same file (`:367`) models its machine properly, -which is the contrast worth noting — the attended path was simply never given -the same treatment: - -```ts -export const UnattendedSessionLifecycleSchema = z.enum([ - "allocating", "provisioning", "connected", "recovering", - "closing", "closed", "expired", "lost", -]); -``` - -**2. The extension never tells the backend.** `apps/extension/src/entrypoints/background.ts:648`: - -```ts -async function detach(): Promise { - const active = session; - try { - if (active !== null) await active.detach(); - } catch (cause) { - log(`detach error (continuing): ${errorMessage(cause)}`, "warn"); - } - await clearAttachment(); - log("detached"); - broadcastState(); -} -``` - -`broadcastState()` updates the side panel only. No frame goes over the -WebSocket, so even with a richer enum the backend could not make the -transition. The same is true of the involuntary path, -`background.ts:595` — which matters more, because it is the one a user -triggers by accident: - -```ts -async function onDetach(source: { tabId?: number }, reason: string): Promise { - await profileClient.sessions.onDebuggerDetach(source); - const active = session; - if (active === null || source.tabId !== active.tabId) return; - await fenceStartedAttendedWrites(); - await clearAttachment(); - log(`debugger detached from tab ${active.tabId} (${reason})`); - broadcastState(); -} -``` - -`chrome.debugger.onDetach` fires when the controlled tab is closed, or when the -user clicks **Cancel** on Chrome's debugger banner. Both leave the session -reporting `connected`. The internal side panel and -`apps/extension/RUNBOOK.md` now explain that the banner is process-wide and -dismissing it can detach the controlled tab, but that operator warning does not -correct the backend’s stale status. - -For completeness, `detached` today is set only on socket-level events, in -`apps/backend/src/session.ts` at lines `529`, `1132`, `1164`, `1198` and `1231`: -connection close, session reconnect / browser-epoch change, device credential -revocation, and terminal close. Losing the debugger attachment is not among -them. - -### Why it was deferred - -It is not a correctness hole in execution. A consumer that sends a command gets -an explicit `ok: false` with a specific reason, not a false success, and -Metamind's connector surfaces that. The exposure is limited to a consumer that -gates on `status` alone and concludes the session is usable. - -It also cannot be fixed in one repo. Adding a value to -`AttendedSessionStatusSchema` is a **breaking protocol change**: the schema is -exported from `@understudy/protocol` and consumers parse responses with it, so -`z.enum` rejects an unknown value. Shipping it needs a protocol major, a -connector release, and a consumer upgrade — coordination that did not belong in -the middle of a canary acceptance run. - -### Proposed fix - -Model the machine, then report the transition. Both halves are required; either -alone changes nothing. - -1. **Protocol.** Add a state meaning "extension socket present, no tab - attached". Recommended name `idle`, giving - `pending | idle | connected | detached`, and keep `connected` meaning - *ready to execute*. Preserving the existing meaning of `connected` is the - point: consumers that already gate on `status === "connected"` keep working - and simply stop treating a detached session as usable. - - *Rejected:* renaming the ready state to `attached` and repurposing - `connected` to mean socket-up. Cleaner on paper, but it silently flips the - meaning of a value existing consumers already branch on — the failure mode - would be worse than the bug. - -2. **Extension.** Send an explicit frame on both detach paths — the deliberate - `detach()` and the involuntary `onDetach()` — so the backend can transition - to `idle`. It must carry the tab identity so a late frame from a superseded - attachment cannot clear a newer one; `sendIfPeerCurrent` in - `apps/extension/src/core/peer-binding.ts` is the existing guard for exactly - this class of post-await staleness and should be reused rather than - reinvented. - -3. **Backend.** Clear `tabs` and `browser` alongside the transition. Reporting a - `tabId` that is no longer controlled is part of the same wrongness and should - not survive the fix. - -### Out of scope - -- The unattended lifecycle. It already models its machine and must not be - touched by this work. -- `SessionAgent`'s existing `detached` transitions. They are correct for what - they describe — socket-level loss — and this adds a state beside them rather - than redefining them. - -### Verification - -- A unit test asserting the full attended sequence: `pending` on create, - `connected` after hello, `idle` after a detach frame, `detached` after the - socket closes. -- A test that a detach frame naming a superseded tab does **not** move a live - session out of `connected`. -- Manually, the scenario that found it: attach, confirm `connected`, press - **Detach tab**, confirm `idle` and empty `tabs`; then repeat by closing the - controlled tab instead of pressing the button, which must reach the same - state. -- Quality gate: clean-code, architecture, and QA lanes, since this is a protocol - change with cross-repo consumers. - ---- - -## A lost lease leaks a browser window - -**Baseline:** branch `dev`, commit `76eaf68`. -**Found:** 2026-07-29, Phase 3b soak run 1. -**Severity:** every device-loss incident strands a Chrome window that only a human will close. Compounds without bound. - -### What was observed - -The soak's device missed its heartbeat past `DEVICE_LOST_MS`, so the coordinator marked its lease `lost`. Hours later the server reported `used 1/2` and the side panel reported `1/2` — both correct — while **two** `example.com` windows were open on screen. Tab `2134210655` belonged to the destroyed lease and was never closed. - -### Why it happens - -Declaring a device lost sets `status = 'lost'` **and `release_at`** on its leases. But the closure list a device receives on sync, in `apps/backend/src/tenant-coordinator.ts:300`, is: - -```sql -SELECT * FROM lease - WHERE device_id = ? AND status IN ('closing','expired') AND release_at IS NULL - ORDER BY created_at -``` - -`release_at IS NULL` excludes exactly the leases that were just released. The server frees the slot and considers itself done; the extension is never told to close the tab, so it doesn't. - -### Proposed fix - -Close the loop on reconnect rather than widening the query blindly — a `lost` lease has `release_at` set precisely because the server has finished with it, and other logic depends on that. - -**Recommended:** on device sync, send a separate *orphan* list — leases with `release_at` set whose device is now back — instructing the extension to close those tabs and forget the assignments. It is advisory, needs no acknowledgement, and is safe to repeat. - -*Rejected:* dropping `release_at IS NULL` from the closure query. Closures are part of the release handshake; feeding already-released leases into it would have the extension re-acknowledge closures the server has settled. - -**Also acceptable and complementary:** have the extension, on reconnect, close any controlled tab whose assignment the server does not acknowledge. That defends against the general case rather than this one path. - -### Verification - -- Coordinator test: a device that reconnects after its leases were lost receives the orphan list. -- Extension test: receiving it closes exactly those tabs and leaves untracked user tabs alone. -- Manually: force a device loss, reconnect, confirm no window survives and the count matches the side panel. - ---- - -## Reconnect backoff does not survive service-worker eviction - -**Baseline:** branch `dev`, commit `76eaf68`. -**Found:** 2026-07-29, inferred from soak run 1 timings. **Mechanism not yet proven** — see the test plan in `docs/plan-network-blip-resilience.md`. -**Severity:** suspected cause of a six-second network blip costing every session on a device. - -### Evidence - -Both reconnect paths schedule with `setTimeout`: - -- `apps/extension/src/core/ws-client.ts:134` — `this.reconnectTimer = setTimeout(...)`, backoff 500 ms doubling to a 30 s cap (`:14`, `:15`). -- `apps/extension/src/core/profile-client.ts:716` — `this.retryTimer = setTimeout(...)`, same shape (`:28`, `:29`). This is the **device control socket**, the one carrying the heartbeat. - -An MV3 service worker is evicted when idle, and a `setTimeout` dies with it. Losing the socket removes the very activity that was keeping the worker alive, so the pending retry is discarded at the moment it is most needed. Recovery then depends on the 30-second `ws-backstop` alarm (`apps/extension/src/entrypoints/background.ts:99`). - -That should still bound recovery near 30 seconds, which is why this is **suspected rather than established**: run 1's device stayed offline for minutes, not tens of seconds. Either the alarm was delayed, or reconnect attempts were firing and failing for another reason — DNS, in the incident that produced this. The test plan is designed to tell those apart. - -### Proposed fix (contingent on the test) - -Do not fix before the mechanism is confirmed; the wrong fix here is easy to justify and useless. If reconnection proves to be timer-death: - -- drive retries from `chrome.alarms` rather than `setTimeout`, accepting the 30-second floor, and keep `setTimeout` only for sub-30-second attempts while the worker is known alive; -- treat the backstop alarm as the authority for "should I be connected", which it nearly is already. - -### Verification - -Reproduce per the plan, capture whether the worker was evicted, whether the alarm fired, and whether reconnect attempts occurred at all. Only then choose the fix. - ---- - -## Ninety seconds without a heartbeat destroys every session on a device - -**Baseline:** branch `dev`, commit `76eaf68`. -**Found:** 2026-07-29, Phase 3b soak run 1. -**Severity:** design question for unattended operation, not a coding error. - -### The numbers - -`apps/backend/src/tenant-coordinator.ts:10-11`: - -```ts -const DEVICE_OFFLINE_MS = 75_000; // reported offline -const DEVICE_LOST_MS = 90_000; // every lease on the device -> 'lost' -``` - -Ninety seconds is roughly four missed heartbeats (`HEARTBEAT_MS = 22_000`). Crossing it sets `status = 'lost'` and `release_at` on every lease the device holds — terminal, `410` to the consumer, work discarded, and a leaked window per the entry above. - -### Why it is a problem - -The tolerance is thinner than the recovery path it must accommodate. Recovery is gated on a 30-second alarm, leaving at most three alarm cycles of slack, and only if every one succeeds. Meanwhile the events that cause a gap this size are utterly routine: a VPN connecting, a Wi-Fi roam, a DNS change. One was enough on 2026-07-29 — and 1Password's socket, hit by the same event, was back in six seconds. - -For an attended session an operator notices and retries. An unattended fleet silently discards in-flight work. - -### Proposed fix - -**Recommended:** separate *capacity reclamation* from *lease destruction*. Freeing a device slot quickly is legitimate; destroying the consumer's session is a different decision that does not need the same deadline. Add a suspended state where the lease stops counting against capacity but remains adoptable if the device returns within a longer window, and destroy only past that. - -*Rejected:* simply raising `DEVICE_LOST_MS`. It trades one arbitrary number for another and delays capacity reclamation for every genuine loss to buy tolerance for transient ones. - -Consider alongside the reconnect entry above — a fix there reduces how often this threshold is reached, but does not make the threshold right. - -### Out of scope - -`DEVICE_OFFLINE_MS`. Reporting a device offline after 75 seconds is accurate and harmless; it destroys nothing. - ---- - -## A leaked browser window is invisible to API monitoring - -**Baseline:** branch `dev`, commit `76eaf68`. -**Found:** 2026-07-29 — the window leak above surfaced only because an operator looked at their own screen. -**Severity:** an acceptance gate that measures less than its name claims. - -The Phase 3b soak checks `capacity_leak` as `deviceUsed > 1`, which is server-side accounting. In the observed leak that accounting was **correct** — the server had released the slot. The leak was entirely client-side, and no API-driven check can see it: nothing exposes how many tabs or windows the extension actually holds versus how many the server believes it holds. - -Any soak or monitor built on the public API therefore cannot enforce "no capacity leak" as written; it can only enforce "no server-side capacity leak". - -**Proposed fix:** have the device report its observed controlled-tab count in the heartbeat, and have the coordinator flag a divergence from its own lease count. That makes the leak detectable remotely and turns the gate into what it claims to be. Until then, treat the gate as partial and confirm tab counts visually during acceptance. - ---- - -## The account plane has no HSTS, so a first plaintext request still crosses the wire - -**Baseline:** branch `dev`, commit `1522cdc` (deployed version `dc9c378e-6e6b-416b-b7ef-038411bc4ae5`). -**Found:** 2026-07-31, during the review of the dashboard CSRF fix. -**Severity:** a first-visit plaintext sign-in POST exposes an email address and a live OTP code to anyone on the path. - -`apps/backend/src/index.ts` now redirects the account plane to `https://` when `url.origin !== CANONICAL_ORIGIN` — but a 308 only fires *after* the request has already been received, body included. Nothing tells a browser not to send the plaintext request in the first place, because no response sets `Strict-Transport-Security`. Cloudflare's Always-Use-HTTPS is an account setting, not a property of this repo, and was off when this was written (`http://understudy.proofof.tech/dashboard` returned `200` before the scheme pin landed). - -Scope it accurately before acting. The dashboard session cookie is `__Host-`-prefixed and therefore `Secure`, so a session token never traverses plaintext regardless. The real exposure is narrower and still worth closing: the `email` field and the 6-digit `code` field of a sign-in POST, on a first visit, before any redirect has been cached. `usk_` MCP bearers are a second case — a client calling `http://understudy.proofof.tech/mcp` now receives a 308, and 308 preserves the body and headers, so the token has already crossed by then. - -**Proposed fix:** add `Strict-Transport-Security: max-age=31536000; includeSubDomains` to the dashboard middleware's header block in `apps/backend/src/dashboard/app.ts` (alongside `Cache-Control`, `Referrer-Policy`, and the CSP), and to the `/mcp` and OAuth responses if they are to be covered too — the header is only honoured when served over https, so it must ride the responses a client actually receives on the canonical origin. Consider `preload` only after confirming no sibling subdomain of `proofof.tech` needs plaintext, since `includeSubDomains` applies to all of them. Enabling Always-Use-HTTPS on the zone is a complementary control, not a substitute, because it lives outside this repo and is invisible to review here. - -**Why deferred:** it is an addition beyond what the CSRF fix set out to do, not a defect in it, and the fix was shipping against a live outage. - ---- - -## Allowed origins are a pairing-time seed, not a live authorization policy - -**Baseline:** branch `dev`, commit `1522cdc` (deployed version `dc9c378e-6e6b-416b-b7ef-038411bc4ae5`). -**Found:** 2026-07-31, during architectural review of the dashboard card reorder. -**Severity:** the dashboard presents a control that reads as an authorization boundary and is not one. Removing an origin does not withdraw it. - -`setAllowedOrigins` (`apps/backend/src/account-directory.ts`) writes **only** `users.allowed_origins`. Nothing touches the paired device's row, and there is no push path to a connected extension. The list reaches a device exactly once, at pairing: `claimPairingCode` copies `user.allowedOrigins` into the `devices` row and returns it as `originPolicy`; the extension persists it and re-declares it on every connect; `DeviceAgent.onMessage` canonicalizes it into `registerDevice`, which stores `origin_policy_json`; and `createLease` (`apps/backend/src/tenant-coordinator.ts`) enforces `isSubset(input.allowedOrigins, origin_policy_json)` against **that** snapshot. `createSession` (`apps/backend/src/api/sessions.ts`) never reads the account's live list. After pairing, the account list has zero runtime effect. - -The consequence is asymmetric with the UI's implication. Adding an origin does nothing until re-pairing — which the copy said. **Removing one also does nothing**, which it did not: the paired browser keeps driving the withdrawn origin until the device is revoked. Re-pairing does not withdraw it either, because `claimPairingCode` inserts a *new* device row and never revokes the predecessor, which remains `revoked_at IS NULL` carrying the older, broader policy. In practice the extension overwrites its own local config so the orphaned `udt_` credential stops being used, but nothing server-side enforces that. - -Mitigated for now in copy only (`apps/backend/src/dashboard/pages.ts`, the Allowed origins card): the card now states that editing does not affect an already-paired browser and that withdrawing an origin requires revoking the browser. - -**Proposed fix:** make the origin policy server-authoritative. Resolve a device's allowed origins from `users.allowed_origins` at lease time — or push them on connect/heartbeat — and treat the extension's declared list as an upper bound to intersect with, never as the authority. Dashboard edits then take effect immediately in both directions, the narrowing gap closes, and pairing-time origins become irrelevant, so the empty-list gate on the pairing button could be deleted for free. Separately, have `claimPairingCode` revoke the superseded device row. - -**Why deferred:** it is a protocol change with a version-skew story (an older extension must keep working against a newer backend), not a UI change, and it was found while shipping an unrelated one-card reorder. Do not fold it into that commit. - -**Note on the gate:** do NOT "simplify" by allowing pairing with an empty origin list before doing the above. Four layers refuse it, and the last one is the trap. (1) The dashboard's disabled button is advisory only. (2) `createPairingCode` (`apps/backend/src/account-directory.ts`) returns `no_origins`, which the route turns into a 303 to `/dashboard?notice=no-origins`. (3) `claimPairingCode` repeats the check for origins emptied between minting and redemption, collapsed to a 404 because every pairing failure mode is deliberately indistinguishable. (4) **`normalizeProfileConfig` (`apps/extension/src/core/profile-client.ts`) is ON the pairing path, not merely a manual-config backstop**: `pairDevice` (`apps/extension/src/entrypoints/background.ts`) feeds the claim response straight into `profileClient.configure()`, whose first statement normalizes and which rejects `originPolicy.length < 1`. `redeemPairingCode` does not check length, so nothing catches it earlier. The wire invariant for the rework is therefore: the claim response must carry at least one canonical origin, or the extension's validator must be relaxed and rolled out FIRST — otherwise every pairing fails with a generic "Pairing failed" after the server has already consumed the single-use code and emitted paired telemetry. - ---- - -## Pairing and per-browser authorization need to be rebuilt - -**Baseline:** branch `dev`, commit `d10c4881eab8e1660c512ccd250261dc64759873`. -**Raised:** 2026-07-31 by the maintainer, after running the first full end-to-end pairing. -**Expanded:** 2026-07-31 by the maintainer, to include link-based Model Context Protocol (MCP) client connection and sign-in. -**Type:** requirements for a follow-up design, not a defect report. - -The current flow — one account-wide origin list, snapshotted once into a device by a copy-pasted 8-character code, with account-wide API tokens — is the minimum that worked. Four changes are wanted, and they interlock enough to be designed together rather than piecemeal: - -1. **Origins settable per browser, and kept in sync.** Today the list is per *account* and reaches a device only at pairing (see "Allowed origins are a pairing-time seed, not a live authorization policy" above). Two browsers paired to one account cannot be given different reach — a personal profile and a work profile get identical authority. The fix for the sync half is the server-authoritative resolution described in that entry; this adds that the authoritative record should be **per device**, with the account list acting as a default for new pairings rather than the only value. - -2. **Link-based pairing instead of code transcription.** The user reads an 8-character code off the dashboard and types it into the side panel. It should be a click: the dashboard offers a link (or QR) that the extension consumes directly. Note the constraint that makes this non-trivial — the code is redeemed by the *extension*, which has no dashboard session, so a clickable link must carry a one-time secret to a context the browser can route to the extension without the page being able to read it. `chrome.runtime.onMessageExternal` with an `externally_connectable` entry for the canonical origin is the obvious mechanism; it changes the manifest and therefore the install-time permission prompt. - -3. **API keys scoped per pairing.** `usk_` tokens are account-wide, so one leaked token drives every paired browser and revoking it breaks all of them. A token should be issuable against a single device, so blast radius and revocation both follow the browser. This also gives the MCP surface a natural answer to "which browser should this call drive?" when an account has several — today `browser_open` picks, and with per-device tokens the token itself decides. - -4. **Link-based MCP client connection and sign-in.** The dashboard currently offers copyable CLI and JSON configuration, while claude.ai and ChatGPT users must open connector settings and paste `https://understudy.proofof.tech/mcp`. Add client-specific **Connect** actions that open a supported MCP client with the canonical resource URL prefilled and start the existing OAuth 2.1 dynamic-registration, Proof Key for Code Exchange (PKCE), consent, and callback flow. Each action must use a documented client deep-link contract. Never place a `usk_` bearer, OAuth authorization code, dashboard cookie, pairing secret, or other credential in the link, browser history, or referrer. Keep the copyable configuration as the fallback for clients without a stable deep-link contract. Done means a signed-out user can follow one link, authenticate and consent in Understudy, return to the originating client, and use `tools/list`; cancellation, an unsupported client, and an expired OAuth state must produce an actionable recovery path without creating a credential. - -**Why deferred:** the first three changes alter the pairing wire contract, and (2) changes the extension manifest, so they carry a version-skew story between an installed extension and a deployed backend. The fourth depends on client-owned deep-link contracts and changes the security-sensitive OAuth entry flow. Design the four changes as one onboarding and authorization model, then roll them out with separate compatibility gates rather than independent dashboard patches. - ---- - -## Page URLs reach the model outside the UNTRUSTED PAGE CONTENT delimiters - -**Baseline:** branch `dev`, commit `1522cdc`. -**Found:** 2026-07-31, while verifying the `understudy-browser` skill against the tool surface. -**Severity:** a prompt-injection surface the code's own header comment says is closed. - -`apps/backend/src/mcp/outcomes.ts` opens by stating that page-derived text — "a11y trees, **page URLs**, extension error strings that may embed page content" — is wrapped in `UNTRUSTED PAGE CONTENT` delimiters. Page URLs are not. `event.url` is interpolated outside the markers in at least `Page snapshot of ${event.url}`, the screenshot caption, and the post-navigation `Now at: ${event.url}.` - -A URL is attacker-influenceable: a redirect, a crafted link, or any page that controls its own query string can put arbitrary text there, and it arrives in the client model's context as trusted server prose. The delimiters are explicitly described in that same comment as the weakest mitigation in the stack, which makes a gap in them cheap to exploit and easy to overlook. - -This matters more now that `.claude/skills/understudy-browser/SKILL.md` ships: it instructs an agent that content inside the markers is data and, by implication, that text outside them is the server speaking. - -**Proposed fix:** wrap the URL, or strip it to origin + path and escape it, at every interpolation site in `outcomes.ts`. Prefer one helper so the guarantee is enforced in a single place, matching that module's stated reason for existing. Then re-read the header comment and make it true of every site, or narrow the claim. - -**Why deferred:** it is a distinct surface from the dashboard CSRF work this was found alongside, and it wants a single-helper fix plus a test that pins delimiter placement rather than a scattered patch. - ---- - -## The MCP surface tells clients refs are single-use; the extension does not consume them - -**Baseline:** branch `dev`, commit `1522cdc`. -**Found:** 2026-07-31, verifying skill guidance against the implementation. -**Severity:** every MCP client is instructed to take a redundant snapshot per action. - -Three places tell clients refs are single-use — `apps/backend/src/mcp/outcomes.ts` ("Refs are fresh for this page state, SINGLE-USE, and die on any navigation") and two descriptions in `apps/backend/src/mcp/tools.ts`. The extension does not implement that: `CdpSession.resolveRef` (`apps/extension/src/driver/cdp.ts`) is `this.refMap.get(ref) ?? null`, a pure lookup with no delete. Refs are scoped to a snapshot generation and remain valid for the whole epoch; `tools.ts` even says elsewhere that scrolling does not invalidate them. - -So the stated contract is stricter than the enforced one. A client obeying it round-trips an extra `browser_snapshot` before every action, which on this surface costs a full command through the queue, the device, and back. - -**Proposed fix:** decide which is true and make both say it. Either consume the ref in `resolveRef` (making the contract real, at the cost of breaking any client that reuses one) or relax the wording to what is enforced — refs are valid until the page navigates or the generation changes. The second is cheaper and matches observed behavior; the first is defensible if single-use is wanted as a guard against an agent acting on a stale mental model. - -**Why deferred:** it is a contract change visible to every connected client, so it wants deciding deliberately rather than as a side effect of a docs pass. +# Track deferred work + +## API-credential vault + +Understudy 0.2.0 deliberately removes the cloud secret vault and generic +`fill_secret` capability.

Later commands return `410`, and reconnecting extensions receive code `4003`. +Known-unsent provisioning failures release the exact fence and return a terminal `closed` handle. A thrown device RPC preserves ambiguity as pollable `closing`. Extension-reported provisioning failure retains a durable release outbox until closure acknowledgement. `DELETE` also preserves that polling handle when close delivery throws after the exact-fenced `closing` state has been committed. -Unattended deletion remains acknowledgement-driven. It returns `202` while the extension still owns the tab or the matching closure frame is pending, then returns `204` after cleanup confirmation. +## Authentication hard cut -`GET /v1/sessions/:id` keeps unattended `closing` sessions pollable with `200`; only unattended `closed`, `expired`, and `lost` sessions return `410`. Attended sessions with a durable closed flag also return `410`, even though their response body retains `status: "detached"`. +- Static MCP tokens use `usk_v2`, bind one active browser and the account’s current `auth_epoch`, and are revalidated on every request. +- OAuth consent requires selecting one active browser. Grant metadata and props carry device ID, auth epoch, and contract version. +- OAuth authorization requires an exact 43-character base64url S256 challenge on both consent render and submission. Plain, missing, malformed, or altered requests fail closed. +- Browser revocation immediately invalidates every bound API and OAuth credential. +- Pre-cutover OAuth props, `usk_v1`, cloud-vault routes, `fill_secret`, `browser_fill_secret`, and `browser_list_secrets` are retired. -## Configure secrets +A normal deployment does not advance authentication epochs.

Rotate a device by adding a higher `credentialVersion` entry and removing the old digest. A heartbeat detects revocation and fences the old socket. +- Narrowing terminalizes affected leases before the policy is recorded and pushed. +- Additions remain unavailable until the extension acknowledges the exact version. +- Offline or stale-policy devices remain paired but cannot receive new work. +- Provision frames carry the policy version and a subset origin list. -Copy `.dev.vars.example` to `.dev.vars` for local development. Never commit `.dev.vars`. +Configured static devices use the same exact schema validator during deployment and at runtime. A connected or returning static device can atomically advance the coordinator from any lower policy version, including across versions it missed while offline, before the extension receives the update. Directory-backed policy remains contiguous and is advanced by the dashboard transaction before it is pushed. -## Configure rollout and quotas +At 75 seconds without a heartbeat, active leases become `recovering`. At 90 seconds they become `suspended`, stop consuming capacity, and receive a 15-minute adoption deadline. Suspended leases still reserve their profile and origins. Same-epoch exact inventory can reconnect them; an exact physical closure terminalizes them as `closed`; new-epoch adoption bumps the lease fence and reprovisions only if capacity, profile, and policy still permit. The deadline terminalizes `lost` and creates exact orphan cleanup. An exact-fenced `closing` or `expired` lease is instead released at the 90-second device-loss boundary, so an unreachable browser cannot reserve capacity indefinitely. -Non-secret Wrangler variables include: +The extension reports managed assignments and owned windows. A newly registered +device remains unavailable until the hello inventory has passed the same +reconciliation used for heartbeats. `/v1/devices` exposes server usage, both +physical counts, missing IDs, divergence, and comparison time.

A prefix entry is a scoped, auditable statement about one namespace, reviewed in source and atomic with `wrangler rollback`. `enabledForTenant` no longer honours `"*"` at all: a wildcard would admit every tenant holding a caller token — the blast radius the allowlist exists to bound — and wildcard enablement is a rejected option in the [rollout runbook](../../docs/unattended-production-rollout.md). Onboard consumer tenants by name, one at a time; self-serve accounts arrive as the `acct-` class. +| Secret | Purpose | +|---|---| +| `AUTH_HMAC_SECRET` | Session IDs, hashes, request fingerprints, CSRF/consent signatures, and telemetry pseudonyms | +| `CALLER_TOKENS` | Legacy caller token to actor and tenant | +| `EXTENSION_TOKENS` | Attended extension token map | +| `DEVICE_TOKENS` | Bootstrap device identities still using configured digests | +| `EXTENSION_ID` | Published Chrome extension ID for direct pairing messages | +| `WS_TICKET_SECRET` | Single-use control and session tickets | -Keep unattended creation disabled during the initial backend deployment. Enable it for a named tenant once that tenant's canary device is enrolled and reporting protocol 2 — the Chromium acceptance suite creates unattended sessions and cannot run against an empty allowlist. +There is no vault KV binding, vault master key, or vault upload key. -`SAFE_WRITE_REQUIRED_TENANTS` guards the **legacy** command path, which is reached only when all of: the caller omits `understudy-command-contract: 2`, the session is attended, and the extension is protocol-1. `@understudy/connector` has sent that header unconditionally since 0.5.0, so a consumer on a current connector never reaches it. +`UNATTENDED_ENABLED_TENANTS` and `SAFE_WRITE_REQUIRED_TENANTS` accept exact tenant IDs or audited `prefix:` classes; `"*"` enables nothing. `QUOTA_POLICY` contains session, command, tenant, device-ticket, and total-command limits. No credential-fill quota remains. -On that path this flag is the **only** refusal. `dispatch()` does not check the protocol version, so with the tenant unlisted a protocol-1 write executes. `dispatchV2` returns the same 426 for a protocol-1 write, but only for callers that reach it — and the legacy path is by definition the one that does not. Enable this flag for a tenant whenever that tenant is enabled for unattended sessions. +Copy `.dev.vars.example` to `.dev.vars` for local development. Never commit `.dev.vars`. -The default exact quotas are: +## Transport and response policy -- 10 session creates/min per actor -- 120 commands/min per session -- 600 commands/min per tenant -- 30 credential fills/min per actor -- 30 device tickets/min per device -- 10,000 admitted commands per session +The canonical host is `https://understudy.proofof.tech`. Canonical HTTP requests receive `308` before routing. Every canonical HTTPS response, including errors, redirects, dashboard, OAuth, MCP, well-known metadata, and `/v1`, carries HSTS. The current staged value is five minutes; do not add `includeSubDomains; preload` until every `proofof.tech` hostname is valid HTTPS and the apex ramp is complete. -The `RATE_LIMITER` binding allows 300 requests/min per authenticated caller or device identity pseudonym.

A device authenticates over HTTPS, receives a signed ticket, and uses it once on the control socket. +Telemetry is content-free. Never add page URL, title, content, dialog text, screenshot data, refs, card aliases, card values, credentials, tickets, or complete socket URLs. -The Worker verifies ticket signature, audience, expiry, and path-bound object name before object routing. The target object consumes the JTI hash atomically and validates current tenant, device, lease, and epoch authority. +## Verify -The extension persists a `closed` record and retries it until the Worker returns an exact `closed_ack`. The coordinator acknowledges the first durable closure, exact closed or expired replays, and exact lost-fence replays while preserving `lost`. It rejects missing leases and stale or mismatched fences. `DeviceAgent` updates the session lifecycle before sending the acknowledgement, and it emits release telemetry only for the first transition. +```bash +pnpm --filter @understudy/backend typecheck +pnpm --filter @understudy/backend test +cd apps/backend +pnpm exec wrangler types --check +pnpm exec wrangler deploy --dry-run --env "" +pnpm exec wrangler deploy --dry-run --env staging +``` -Deploy this backend behavior before the acknowledging extension.

It refreshes `origin/master` and requires +the source SHA to remain its current head before preparation, secret upload, +and deployment.

The +evidence file exists before the first secret upload and is updated to `failed` +or `verified` by an exit trap. +The device-token upload helper applies Wrangler's trailing-whitespace +normalization before hashing, passes those exact normalized bytes to Wrangler, +and aborts before invoking it if the normalized source changed after preflight. + +A production code rollback does not by itself prove that `DEVICE_TOKENS` and +`EXTENSION_ID` returned to their prior values.

A later compatibility-contract change blocks automatic deployment and requires this wrapper again. Credential revocation, cloud-vault deletion, DNS changes, and HSTS ramp changes remain explicit operator actions.
