feat(grok): reset-coupon inspection + gated redemption (gRPC-Web, journaled idempotency) - #4306
Conversation
…demption Read Grok consumer reset coupons via prod_mc_billing.ConsumerUiSvc/ GetRemainingResets and redeem via RedeemReset using the stored xAI OIDC token (Bearer + X-XAI-Token-Auth: xai-grok-cli, no cookies). Hand-rolled gRPC-Web envelope codec (0x00 data / 0x80 trailer frames), minimal protobuf codec for the verified wire contract, and a crash-safe operation ledger with UUIDv4 idempotent replay mirroring the Codex reset-credit pattern. Tests registered in the layout map.
…led consume GET /api/grok/reset-coupons?accountId= inspects remaining reset tokens and validity windows; POST /api/grok/reset-coupons/consume redeems one with UUIDv4 operation-id idempotency: the operation is journaled before the upstream call, identical ids replay the durable settlement, foreign ids 409, exhausted ledger 503. Route registered in the management table (mutates: true) and dispatched lazily like the quota routes so nothing eager-loads the module. New ocx account grok-reset-coupons mirrors reset-credits: --consume requires --yes, --operation-id validated as UUIDv4 client-side; flag-shaped positionals are never eaten as the account id.
…cales Reference pages (cli/providers-accounts.md, management-api.md) gain the new ocx account grok-reset-coupons subcommand and the two management routes in English and all seven translated locales, and structure/providers/xai-grok.md records the gRPC-Web billing parity contract under its hardening section.

This POST permanently exhausts a billing coupon but accepts the ordinary management admin token, and the new CLI invokes it after checking only a caller-supplied --yes; an agent can supply that flag or call the endpoint directly. Require ctx.principal === "gui-session" before performing the mutation, as with the existing user-consent endpoint, rather than exposing consumption through the raw-token CLI path.

There was a problem hiding this comment.
When two overlapping requests reuse one operation ID and account but specify different token IDs, the second request passes this identity check because only accountId is compared; the route then redeems its newly requested token rather than opRecord.tokenId, so both coupons can be consumed under an ID advertised as idempotent. Include tokenId in the ownership comparison and ensure resumed execution always uses the coupon durably bound to the operation.

Once the journal reaches 256 entries, this early return prevents every subsequent write, including the write path that performs the 30-day pruning, and it also prevents replaying an existing operation because lookup occurs afterward. A busy installation can therefore become permanently unable to redeem or replay coupons until the file is manually removed; prune before counting and handle existing operation IDs before rejecting new capacity.

When Grok stalls or the management client disconnects, this irreversible redemption receives neither req.signal nor a timeout even though the client API accepts a signal, so the handler can remain pending and redeem after the caller has gone away; a retry with the default fresh operation ID can then consume another coupon. Pass a bounded signal composed with the request-abort signal to both upstream coupon operations.

Useful? React with 👍 / 👎.
… surface The capability/route parity ratchet requires every management route to be capability-covered, exempt, or ratcheted. The new grok reset-coupon routes are genuinely covered by the new ocx account grok-reset-coupons verb, so they are declared here (routes, flags, idempotency note) and the committed skill surface map is regenerated.

In `@devlog/_plan/260912_grok_reset_coupons/010_phase1_core_client.md`:
- Around line 527-536: The getGrokRemainingResets request must retry once after
an HTTP 401 using forceRefreshOAuthAccessSnapshot(tokenSnapshot), then replay
with the refreshed bearer token; preserve existing error handling for non-401
responses and failed refreshes. Update handleGrokCouponRoutes to use this
refresh-and-retry flow, and test it through the real OAuth refresh seam rather
than only mutating activeToken.
- Around line 352-383: Update decodeVarint to accumulate the int64 varint using
bigint rather than JavaScript bitwise number operations, then convert only after
validating the value is within the supported safe integer range; preserve
bytesRead behavior and reject or safely handle out-of-range timestamps used by
decodeTimestamp.
- Around line 704-743: Serialize all synchronous ledger read–modify–write
mutations in the grok reset coupon flow using withConfigMutationLockSync,
including both the claim in openGrokResetCouponOperation and settlement updates.
Add an explicit in-flight claim state so an existing open operation is not
returned as executable to a concurrent request; only the original claimant may
dispatch redemption, while subsequent requests receive the appropriate
in-progress result. Preserve replay behavior for settled operations and ensure
settlement writes use the same lock.
In `@devlog/_plan/260912_grok_reset_coupons/020_phase2_surfaces.md`:
- Around line 180-198: The reset-coupon handler must resolve an existing
operation ID before validating current xAI credentials. Move the
openGrokResetCouponOperation ledger lookup and replay/identity-mismatch handling
ahead of getValidAccessSnapshotForAccount, while resolving credentials only when
the operation is in the execute state; preserve the journaled replay response
and 409 mismatch behavior.
- Around line 296-302: Update the catch path around
recordGrokResetCouponSettlement so only confirmed gRPC rejection responses
record code "redeem_failed" with status "failed"; classify timeouts, connection
resets, and other pre- or post-dispatch transport errors as an unknown outcome
that remains retryable. Preserve the existing settlement recording for confirmed
rejections while preventing uncertain transport failures from being marked
permanently failed.
- Around line 214-220: Align the 409 error code for the identity-mismatch path
across the handler, documentation, and tests. Update the response returned by
the identity-mismatch branch and every corresponding expectation or documented
value to use one consistent code, preserving the existing behavior and message.
- Around line 270-302: The redemption flow around redeemGrokResetCoupon and
recordGrokResetCouponSettlement must distinguish upstream redemption errors from
settlement-write errors. Ensure a successful redemption is not caught as
redeem_failed when its settlement write fails; preserve an indeterminate
recovery state and avoid reporting the irreversible upstream redemption as
failed.
- Line 134: Update jsonResponse in the coupon route flow to include a
Cache-Control: no-store header for account-specific JSON responses, and add a
regression test verifying the header is present. Ensure responses for both
requested and active accounts use this policy.
- Around line 150-157: Validate the parsed body in the Grok coupon request
handler before destructuring it: reject null and non-object values with the
existing 400 invalid-request response, then destructure only after that guard.
Validate any present request fields, including tokenId and operationId, as
strings while preserving resolveTargetAccountId’s existing accountId error
handling.
In `@devlog/_plan/260912_grok_reset_coupons/030_phase3_delivery.md`:
- Around line 97-125: Update the “030 Verification Runbook” to include the
required docs-site validation: change into docs-site, run bun install
--frozen-lockfile, then run bun run build, and require all commands to complete
successfully alongside the existing verification steps.
In `@docs-site/src/content/docs/fr/reference/management-api.md`:
- Line 82: Update the 409 error code in the endpoint reference table in
docs-site/src/content/docs/fr/reference/management-api.md lines 82-82 from
identity_mismatch to operation_id_owned_by_another_account, and make the same
replacement in docs-site/src/content/docs/ja/reference/management-api.md lines
68-68. No other endpoint behavior or documentation should change.
In `@docs-site/src/content/docs/reference/management-api.md`:
- Line 82: Update the 409 error code for POST /api/grok/reset-coupons/consume to
operation_id_owned_by_another_account, matching the behavior of the grok coupon
route. Apply the same correction in

docs-site/src/content/docs/zh-cn/reference/management-api.md lines 68-68 and
docs-site/src/content/docs/zh-tw/reference/management-api.md lines 68-68.
In `@src/cli/account.ts`:
- Line 63: Update the top-level `grok-reset-coupons` usage entry in the account
CLI help to include the existing `--operation-id <uuid>` option, matching the
option accepted by `account-auth.ts` without changing command behavior.
In `@src/cli/registry.ts`:
- Line 237: Update the grok-reset-coupons help text in the CLI command registry
to document the supported --token-id <token-id> and --operation-id <uuid> flags
alongside the existing options, preserving the descriptions of coupon
inspection, redemption, and retry-safe operation IDs.
In `@src/grok/grpc-web.ts`:
- Line 111: Update decodeGrpcWebResponse() and parseGrpcWebTrailers() to fail
closed: require complete frame consumption, a terminal trailer, and exactly one
strictly valid grpc-status value, rejecting missing trailers, missing status,
trailing partial headers, and malformed values such as 0invalid. Ensure
redeemGrokResetCoupon() cannot record or return successful redemption for these
malformed HTTP 200 responses, and add regression coverage for each listed case.
In `@src/grok/reset-coupon-ledger.ts`:
- Around line 46-54: Update the ledger-loading logic in reset-coupon-ledger.ts
so read, parse, or validation failures return an unavailable result instead of {
version: 1, operations: {} }. Propagate that unavailable state through the
reset-coupon-ledger handler and map it to HTTP 503, while preserving the
existing valid-ledger behavior.
- Around line 78-80: Update the operation handling around the capacity check in
the reset-coupon ledger flow to resolve an existing operation ID before
rejecting at MAX_GROK_RESET_COUPON_OPERATION_IDS. Prune settled and failed
entries older than the 30-day retention period before counting operations, then
enforce capacity using the remaining entries while preserving replay behavior.
- Around line 99-104: Update the existing-operation branch in the reset-coupon
flow so an already-open operation is treated as in-doubt or replay-safe rather
than returning a fresh execute request. Persist the resolved tokenId before the
upstream call, avoid selecting another coupon, and require both accountId and
tokenId to match before reusing the operation. Add a regression test covering a
restart after upstream redemption succeeds but before settlement.
In `@src/grok/reset-coupons.ts`:
- Around line 63-75: Update decodeVarint to throw when no bytes are available at
the starting offset or when the input ends before a terminating byte, rather
than returning a partial result. Also reject overlong varints when the shift
limit is exceeded, and ensure decodeGetRemainingResetsResponse propagates these
errors instead of allowing offset to remain unchanged and the outer loop to
continue.
- Around line 221-225: Update getGrokRemainingResets and redeemGrokResetCoupon
to enforce a bounded internal timeout on each fetchImpl request, combining that
timeout signal with options.signal while preserving caller cancellation. Clear
the timeout after each request completes, and allow timeout errors to propagate
to the existing route handlers and their established 502 responses.
- Around line 233-240: The getGrokRemainingResets response handling must require
exactly one decoded message after validating the terminal status. Replace the
empty-message fallback with validation that rejects any decoded.messages length
other than 1, then decode only that single unary response message.
In `@src/server/management/grok-coupon-routes.ts`:
- Line 126: Validate the result of req.json() in the Grok coupon request handler
before destructuring it: reject null, arrays, and all non-object JSON values
with HTTP 400, while preserving valid object bodies for
GrokConsumeCouponRequestBody processing.
- Around line 174-185: Update the replay branch for settlement records in the
relevant route handler to persist and reuse the original response
classification, including the HTTP status and whether the response contains an
error object. Ensure replays of no_coupons_available return HTTP 400 and replays
of redeem_failed return HTTP 502 with the original response shape, while
successful settlements continue returning HTTP 200.
- Around line 234-240: Update the catch branch in the coupon inspection flow to
settle the operation opened before inspection, recording a retryable
pre-redemption failure or safely removing the unused ledger entry before
returning the 502 response. Use the existing operation/ledger APIs and preserve
the current error response behavior.

Accumulate Timestamp.seconds without 32-bit bitwise arithmetic.
decodeTimestamp passes the int64 seconds field to decodeVarint in src/grok/reset-coupons.ts:97-119. The bitwise expression at lines 66-68 truncates values to signed 32-bit integers, so a valid future validityStart or validityEnd timestamp at or above 2^31 seconds can produce an incorrect ISO date at lines 161-162.

Retry once after an upstream 401 in the production route.
handleGrokCouponRoutes resolves one tokenSnapshot and passes its bearer to getGrokRemainingResets at src/server/management/grok-coupon-routes.ts:81-116; src/grok/reset-coupons.ts:214-231 throws immediately on HTTP 401, so a stale but refreshable xAI credential can become a 502. Use forceRefreshOAuthAccessSnapshot(tokenSnapshot) and replay the request once with the refreshed token.

Serialize the ledger claim and settlement updates.
src/server/management/grok-coupon-routes.ts:166-214 calls openGrokResetCouponOperation before dispatching redeemGrokResetCoupon. src/grok/reset-coupon-ledger.ts:75-114,128-140 performs unguarded read–modify–write operations. Separate processes can race and overwrite ledger entries. A second request also receives "execute" for an existing "open" record, so it can redeem the same operationId while the first request is in progress. Use withConfigMutationLockSync for the synchronous ledger mutations, and add an explicit in-flight claim so a second request cannot dispatch the same operation. Apply the lock to settlement writes as well.

Set Cache-Control: no-store on account-specific JSON responses.
src/server/management/grok-coupon-routes.ts:58-101 returns coupon data for the requested or active account through jsonResponse. src/server/auth-cors.ts:260 does not set a cache policy. Add Cache-Control: no-store in jsonResponse and add a regression test for this header. Otherwise, the browser can reuse one account’s coupon list after an account switch.

Validate the request body before destructuring.
At src/server/management/grok-coupon-routes.ts:124-131, req.json() can return null; destructuring then throws outside the JSON parse try block instead of returning a 400 response. Reject a null or non-object body before destructuring, then validate present fields against their declared string types. accountId type errors are already caught by the surrounding resolveTargetAccountId() handler.

Add a bounded timeout to both xAI requests.
getGrokRemainingResets and redeemGrokResetCoupon pass only options.signal to fetchImpl at src/grok/reset-coupons.ts:221-225 and 255-259. The management callers omit that signal, so a stalled xAI request can remain pending without a bound. Add an internal timeout, combine it with options.signal, and clear the timer after completion. Let timeout rejection reach the existing route handlers, which return the established 502 upstream error responses.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Require exactly one unary response message for GetRemainingResets.
Once the terminal trailer has status 0, getGrokRemainingResets returns { tokens: [] } when decoded.messages is empty. A trailer-only response therefore reports no coupons instead of rejecting the incomplete unary response. Reject responses unless decoded.messages.length === 1 before decoding the message.

Validate that the JSON body is a non-null object.
req.json() can return null. Line 131 then destructures null and throws, which converts an ordinary invalid request into an unhandled server error.
Reject null, arrays, and non-object JSON values with HTTP 400 before destructuring.

Replay the original HTTP outcome.
The first no_coupons_available response is HTTP 400, and the first redeem_failed response is HTTP 502. A retry of either settlement returns HTTP 200 with no error object.
Store the original response classification and replay the same status and response shape. Do not convert a persisted failure into a successful HTTP response.

Settle or remove the operation after a pre-redemption inspection failure.
The operation is opened before coupon inspection. If inspection fails, this branch returns without updating the ledger. Open entries are never pruned.
Repeated failures with new operation IDs can permanently fill all 256 slots. Record a retryable pre-redemption failure or safely remove the unused operation.

The check runs against the PR merge commit, so #4306 landing on dev made the committed map one capability short of regeneration.
The coupon routes shipped in lidge-jun#4306 with a CLI verb and no dashboard surface. Each xAI OAuth row now carries a ticket badge with its remaining coupon count, and the badge opens a dialog that lists validity windows and redeems the coupon closest to expiry. Three behaviours are deliberate rather than incidental: - Redemption truth is the settled ledger code, not HTTP 200. The route replays a settled failure as 200 with replayed: true and the original code, so reading only that flag would announce a failed redemption as a completed reset. - The roster epoch and the per-account request token are separate, so one row's retry cannot discard a sibling row's in-flight read. - An aborted redemption stops posting. The route re-executes a redemption whose journal record is still open, so a retry after a timeout can spend a second coupon; the dialog holds its operation id, reports the outcome as unknown, and offers only a re-read. Reads are bounded to three in flight and cover only the accounts of the open provider.
