Real PHC-format Argon2id hashes (Marcus Ilori's ruling, handoff-03-auth.md v7)**\n- `client_secret_hash` was a bare `<base64-salt>$<base64-hash>` verified against this package's own compile-time cost constants — not self-describing like `user_credential.secret`'s own Argon2id encoding. `oauth_client` deliberately has no `hash_algo`/`hash_cost` columns *because* the hash is supposed to be self-describing; the old encoding quietly broke that assumption, so a future cost-profile bump would have made every existing hash unverifiable at once with no way to tell an old row from a new one (Priya Nandakumar's finding).\n- Fixed: `hashSecret` now emits `«REDACTED-ARGON2»`; `verifySecret` parses it and recomputes from the **embedded** parameters, never this package's own current constants.\n- The trap Priya named explicitly — a verifier that parses the string but still recomputes from compile-time constants would pass every round-trip test while making the self-description pointless — is closed by `TestVerifySecret_ReadsEmbeddedParameters_NotPackageConstants`, which hand-constructs a hash at `t=2` (not this package's current `t=1`) and confirms it still verifies. That's the only way that test passes.\n- Added verify-then-rehash-on-next-successful-auth: `ClientStore` gained `UpdateSecretHash`; a successful grant against a hash whose embedded parameters have drifted from the current profile re-hashes and persists it, best-effort (never fails a grant already earned by a correct secret).\n- `deploy/gen-argon2-hash.go` now emits the same PHC shape; its actual command-line output was round-tripped through `verifySecret` directly (not just format-inspected) before being removed from the working tree.\n- `deploy/demo-data/qa-client-bootstrap.md` documents the format change: **any row seeded before this PR must be re-seeded — Theo re-runs the runbook once** for the QA client, per the PM's sequencing ruling.\n\n**2. Goose statement-splitting bug (live deploy failure, run 34758490265)**\n- The `CREATE FUNCTION oauth_client_set_updated_at() ... $$ ... $$` block in `migrations/issuer/00001_initial_schema.sql` broke goose's real CLI parser (SQLSTATE 42601, \"unterminated dollar-quoted string\") — goose splits on every semicolon unless a block is wrapped in `-- +goose StatementBegin`/`StatementEnd` markers. The earlier DDL review verified this file directly via `psql`, which has no such splitting behavior and could not have caught a goose-CLI-specific bug.\n- Fixed with the markers. Legitimate to edit `00001` in place: `goose_db_version_issuer` has never been populated anywhere — this migration has never successfully applied.\n- **Closed the actual test-harness gap that let this ship**: `clientstore_pg_test.go`'s `setupIssuerDB` previously extracted the migration's `-- +goose Up` section as raw text and `Exec`'d it as one blob — never exercising goose's own statement splitter, so no amount of running it could have caught this class of bug. Rewrote it to call `goose.Up` (`pressly/goose/v3`, the same library the real `goose` CLI is built on) against the actual migration directory. Caught immediately on first run: the rewritten harness failed because an explanatory comment of mine accidentally looked like a goose annotation — exactly the class of parser-specific mistake a blob-`Exec` harness can never surface, which is the whole point of the fix.\n\n## Test plan\n- [x] `go build ./...`, `go vet ./...`, `go test ./...` clean\n- [x] Real-Postgres integration run (throwaway `postgres:16-alpine` container) via the new `goose.Up`-based harness — schema/CHECK/trigger tests all pass through the actual goose parser, not a hand-rolled blob exec\n- [x] New `TestPostgresClientStore_UpdateSecretHash`/`_NoSuchClient` against real rows\n- [x] New `TestVerifySecret_ReadsEmbeddedParameters_NotPackageConstants`, `TestHashSecret_EmitsPHCFormat`, `TestNeedsRehash`\n- [x] New `TestNewTokenHandler_DriftedHashCostProfile_RehashesOnSuccess` — a drifted-parameter hash verifies correctly and triggers exactly one `UpdateSecretHash` call\n- [x] `deploy/gen-argon2-hash.go`'s actual `go run` output round-tripped through `verifySecret` directly\n\n## Who did the work\n- Lead: Renata Cole (03-engineering-delivery)\n- Finding (PHC): Priya Nandakumar (05)\n- Ruling (PHC): Marcus Ilori (02)\n- Finding (goose split): Theo (04) — live deploy failure + independent local repro\n- Models: Claude Sonnet 5\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\n\nhttps://claude.ai/code/session_011Cuba4JUvrsQCrTdUj4yzk\nEOF\n)\" 2>&1"

"description": "Oren review of PR #39 PHC fix and goose fix",
"subagent_type": "oren-castellan",
"prompt": "Review PR #39 on github.com/wtvamp/loginid-takehome, branch fix/oauth-client-phc-hash, for track 03-engineering-delivery. Worktree at /Users/warrenthompson/Source/LoginID-worktrees/LT-51-phc-fix (based on origin/main).\n\nContext: LT-51 (OAuth2 client-credentials grant) already merged. Two follow-up fixes bundled in this PR:\n\n1. Priya Nandakumar (05) found that internal/api/clientstore.go's hashSecret/verifySecret stored/verified Argon2id hashes as a bare \"<base64-salt>$<base64-hash>\" against the package's own compile-time cost constants (argon2Time/argon2Memory/argon2Threads), not a self-describing PHC string («REDACTED-ARGON2» like user_credential.secret elsewhere in this project uses. The whole reason oauth_client has no hash_algo/hash_cost columns is that a PHC string is supposed to be self-describing — the old encoding silently broke that, so a future cost-profile bump would make every existing hash unverifiable at once with no way to tell an old row from a new one. Marcus Ilori (02) ruled the fix in handoff-03-auth.md v7: real PHC string, verify from PARSED parameters (not recompute from the package's own constants — that's the trap: a verifier that parses the string but still uses the compile-time constants would pass every round-trip test while making the self-description pointless), plus verify-then-rehash-on-next-successful-auth (on a successful grant, if the stored hash's embedded parameters differ from the current profile, re-hash and persist, best-effort).\n\n2. Separately, Theo (04) found and reproduced a real deploy failure: migrations/issuer/00001_initial_schema.sql's CREATE FUNCTION ... $$ ... $$ plpgsql block broke goose's real CLI parser (SQLSTATE 42601, unterminated dollar-quoted string) because goose splits on every semicolon unless a block is wrapped in \"-- +goose StatementBegin\"/\"StatementEnd\" markers — the earlier DDL review had only verified the file via psql directly, which has no such splitting behavior. Fixed with the markers. Also fixed the actual test-harness gap that let this ship: internal/api/clientstore_pg_test.go's setupIssuerDB previously extracted the migration's \"-- +goose Up\" section as raw text and Exec'd it as one blob, never exercising goose's own statement splitter — rewritten to call goose.Up (github.com/pressly/goose/v3, the same library the real goose CLI is built on) against the actual migration directory.\n\nFiles changed (read from the worktree):\n- internal/api/clientstore.go — hashSecret/encodePHC/parsePHC/parsePHCParam/verifySecret/needsRehash, new UpdateSecretHash method on PostgresClientStore and the ClientStore interface\n- internal/api/clientstore_test.go — TestHashSecret_EmitsPHCFormat, TestVerifySecret_ReadsEmbeddedParameters_NotPackageConstants (hand-builds a hash at t=2, confirms it verifies — proving parameters are read, not assumed), TestNeedsRehash\n- internal/api/clientstore_pg_test.go — setupIssuerDB rewritten to use goose.Up; new TestPostgresClientStore_UpdateSecretHash/_NoSuchClient\n- internal/api/tokenhandler.go — success path now calls needsRehash/hashSecret/store.UpdateSecretHash after RecordSuccess, best-effort (logged, not fatal)\n- internal/api/tokenhandler_test.go — fakeClientStore gained UpdateSecretHash; new TestNewTokenHandler_DriftedHashCostProfile_RehashesOnSuccess\n- migrations/issuer/00001_initial_schema.sql — added \"-- +goose StatementBegin\"/\"StatementEnd\" around the CREATE FUNCTION block\n- deploy/gen-argon2-hash.go — now emits PHC format\n- deploy/demo-data/qa-client-bootstrap.md — documents the format change and that existing seeded rows need re-seeding\n- go.mod/go.sum — added github.com/pressly/goose/v3 as a dependency (test-only usage)\n\nPlease run `go build ./...`, `go vet ./...`, and `go test ./...` yourself in that worktree, then focus on:\n1. Is verifySecret's parsing actually correct and safe — parsePHC's exact split-on-\"$\" logic (expects 6 parts: \"\", \"argon2id\", \"v=19\", \"m=...,t=...,p=...\", salt, hash), parsePHCParam's name-must-match-position check. Any edge case that could misparse a malformed-but-plausible-looking string into something that verifies incorrectly, or panics instead of returning an error?\n2. needsRehash: correctly compares parsed.memory/time/threads against argon2Memory/argon2Time/argon2Threads — any case where a hash that SHOULD be flagged for rehash isn't, or vice versa?\n3. The rehash wiring in tokenhandler.go — confirm it can only ever trigger on the genuine real-hash-verified path (not the dummy-hash path), and that a failure to rehash (hashSecret error or UpdateSecretHash error) is correctly non-fatal to the grant response already earned.\n4. UpdateSecretHash's WHERE clause (`client_id = $1 AND secret_state = 'set'`) and its RowsAffected-based error — is treating 0-rows-affected as an error still correct/safe, or could it ever misfire against a legitimate concurrent scenario?\n5. The goose StatementBegin/StatementEnd fix — does the migration file's Down section need equivalent markers (DROP TRIGGER/DROP FUNCTION are simple single statements, but confirm)?\n6. Anything else: error handling, nullability, off-by-one, idiom, naming, doc-comment accuracy — your usual review lens.\n\nReport your findings in plain prose to Renata Cole (03 lead), as you'd normally report a review. If everything holds up, say so plainly."

Answering your question directly — my earlier real-Postgres integration run applied the migration via a hand-rolled \"extract the Up section, Exec it as one blob\" approach, NOT through goose itself, which is exactly why it didn't catch this. Fixed that too: clientstore_pg_test.go now calls goose.Up (pressly/goose/v3, same library the real CLI is built on) against the actual migration directory, so the test now runs the real parser. Caught immediately on first run against the fixed migration — my own explanatory comment accidentally looked like a goose annotation and broke the parse, which the old blob-exec harness could never have surfaced either way.\n\nReviews on the PR: Oren's running now.

Also spun up an ephemeral Postgres container to run the skipped integration tests for real rather than trust the skip message — \\`TestPostgresClientStore_*\\` and the schema-constraint/trigger tests all pass against actual Postgres via \\`goose.Up\\`. Re-ran \\`goose.Up\\` against the pre-fix migration text (commit 5dc78df) in a scratch schema and reproduced the exact failure Theo reported — SQLSTATE 42601, unterminated dollar-quoted string — confirming the StatementBegin/StatementEnd fix is real, not cosmetic.\n\n1. **Real finding, now fixed:** \\`parsePHC\\`'s version field used \\`fmt.Sscanf(parts[2], \"v=%d\", &version)\\`, which doesn't require consuming the whole input — \\`\"v=19x\"\\` would silently parse as version 19 with \\`\"x\"\\` discarded, inconsistent with \\`parsePHCParam\\`'s own stricter whole-field parsing for m/t/p. Doesn't cause a mis-verify (salt/hash still have to match), but it's exactly the \"malformed-but-plausible\" gap this function otherwise guards against.\n2. \\`needsRehash\\` — correct. Only reports true when parameters actually differ, treats a parse failure as false (safe default, only ever called post-verify), and the hand-built \\`t=2\\` test proves it reads real parsed values.\n3. Rehash wiring — correct. \\`secretOK\\` is only ever true on the real-hash branch (dummy-hash branch always sets it false), so rehash only ever runs after a genuine verify. Both failure modes are logged only, never turn a successful grant into a failure.\n4. \\`UpdateSecretHash\\`'s zero-rows-affected handling is correct; the doc comment said \"not an error\" directly above a statement returning one — self-contradictory wording, now fixed.\n5. Down section — correct, no markers needed. DROP TRIGGER/FUNCTION/TABLE are ordinary single statements, no dollar-quoting.\n6. Everything else holds up — position-must-match-name check in \\`parsePHCParam\\`, constant-time comparison post-parse, test coverage is genuinely load-bearing (both hand-built-parameter tests would fail if \\`verifySecret\\` were \"fixed\" back to using package constants, which is exactly the trap this exists to catch).\n\n**Fixed in 6ab3d6e:** version field now parsed via \\`parsePHCParam\\` (same strict whole-field parsing as m/t/p), with a new malformed-hash test case (\\`\"v=19x\"\\`) locking it in.

The vendor-presented token is scoped to `FetchIdentity`'s own call only, never assigned to a wider-scoped variable (**attack-tree leaf 4**).\n- `cmd/idp-connector/main.go` wires the real router, choosing `HTTPVendorClient` when `IDP_ABC_BASE_URL` is configured or the in-process stub (seeded with one demo identity) otherwise.

"subagent_type": "oren-castellan",
"prompt": "Review PR #40 on github.com/wtvamp/loginid-takehome, branch feature/LT-41, for track 03-engineering-delivery. This implements LT-41 (Q3): the idp-connector binary's POST /auth and POST /identity handlers against a stubbed third-party vendor. Worktree at /Users/warrenthompson/Source/LoginID-worktrees/LT-41 (based on origin/main).\n\nContext: refinement/LT-41.md and 02-ai-security-architecture/connector-security.md are the design docs (both worth reading in full — connector-security.md especially, since most of this story's requirements come directly from its §1-§6 and its attack-tree table at the bottom). Key points:\n- The assignment's fixed contract: POST /auth takes {\"username\",\"password\"}, returns access_token; POST /identity takes {\"phone\",\"name\"}, returns PII (name, phone, street_address, locality, region, postal_code, country).\n- No real ABC/XYZ vendor exists (explicit non-goal) — a stub is fine.\n- Attack-tree leaf 1: a fresh, isolated Authorization header must be built per outbound vendor request, never inherited from HTTP connection/keep-alive reuse.\n- Attack-tree leaf 4: the vendor token variable must be scoped to the narrowest function possible, never passed up the call stack; excluded from any generic request/response dump used in panic traces/debug output.\n- Attack-tree leaf 5: outbound vendor calls rate-limited per calling-API-client identity AND per source IP independently, with a stricter threshold on vendor-auth failure ratio specifically (not just volume) — this PR reuses the already-built api.GrantLimiter (PR #30/#34) rather than building a new component, per this story's own non-goal (\"no shared rate-limit store... this story's own in-process rate limiting is sufficient, matching the pattern already used for RateLimiter/TouchCounter/GrantLimiter\").\n- /identity must fail closed with a generic error that doesn't distinguish \"no token\"/\"bad token\"/\"vendor rejected it\" in response CONTENT, plus (Marcus Ilori's ruling on a Tobias Lindqvist timing-oracle objection) apply a ~100ms uniform floor across those three failure branches — explicitly a partial mitigation, not full closure, since a real vendor round-trip's latency isn't controllable.\n- The connector's own /auth and /identity must validate an inbound JWT with a DISTINCT audience (idp-connector-service, not api-service's loginid-api-service) and scope (connector:identity-lookup) — a new Scope constant was added to internal/api/auth.go and internal/api/jwtmiddleware.go's singleScope recognized-scope switch.\n- Never log the vendor password, vendor access_token, or raw vendor error response bodies, in any environment or error path.\n\nFiles to review (all new unless noted):\n- internal/connector/vendorclient.go — VendorClient interface (Authenticate, FetchIdentity), Identity struct matching the assignment's PII field list exactly.\n- internal/connector/stubvendorclient.go — StubVendorClient: in-process fake, Seed(username,password,identity), Authenticate/FetchIdentity backed by simple maps with a mutex.\n- internal/connector/httpvendorclient.go — HTTPVendorClient: NewHTTPVendorClient requires an https:// baseURL (errors otherwise); a module-level defaultVendorHTTPClient with a bounded Transport (MaxIdleConns/MaxIdleConnsPerHost/MaxConnsPerHost/IdleConnTimeout) and an explicit http.Client.Timeout; Authenticate/FetchIdentity each build a fresh *http.Request via http.NewRequestWithContext with the token set directly on that request's header (never a client-level default), assume the vendor shares this project's own JSON shape (a stated simplifying assumption), and collapse every failure mode (dial error, non-200 status, decode failure) to one of two sentinel errors (ErrVendorAuthFailed / ErrVendorIdentityNotFound) without ever reading/logging the raw response body on failure.\n- internal/connector/handlers.go — NewAuthHandler, NewIdentityHandler, Deps struct (Vendor, Limiter, AuditLog), a local unexported vendorLimiter interface (satisfied by api.GrantLimiter). NewIdentityHandler: rate-limit gate first (before touching anything else, keyed by AuthContext.Sub + source IP), then body decode, then the vendor token read from the X-Vendor-Access-Token header, then FetchIdentity — every failure path routes through waitForFloor(start) + writeIdentityFailure(w), the single call site for the byte-identical response. NewAuthHandler: rate-limit gate, decode body, Authenticate, generic failure on any error.\n- internal/app/connector_router.go — NewConnectorRouter: mounts /healthz, POST /auth, POST /identity behind NewJWTMiddleware(keys, cfg.AuthJWTIssuer, cfg.ConnectorJWTAudience, auditLog) + NewDeadlineMiddleware, constructs one shared api.InProcessGrantLimiter instance for both handlers.\n- cmd/idp-connector/main.go — chooses HTTPVendorClient (if cfg.IDPABCBaseURL set) or a StubVendorClient seeded with one demo identity (otherwise); builds a JWKSCache from cfg.AuthJWKSURL.\n- internal/api/auth.go, internal/api/jwtmiddleware.go — added ScopeConnectorIdentityLookup and recognized it in singleScope's switch (shared scope vocabulary/JWT verification mechanism reused across both binaries).\n- Tests: internal/connector/handlers_test.go, httpvendorclient_test.go, stubvendorclient_test.go, internal/app/connector_router_test.go.\n\nPlease run `go build ./...`, `go vet ./...`, and `go test ./... -race` yourself in that worktree, then focus on:\n1. Does the \"fresh header per request, never inherited from connection reuse\" property actually hold under real connection pooling — read httpvendorclient.go's Authenticate/FetchIdentity carefully; is there any shared/client-level state (a header map, a captured request object) that could leak across concurrent or sequential calls with different tokens, beyond what the existing test already covers?\n2. Is the token variable's scope in handlers.go's NewIdentityHandler actually as narrow as claimed — does `token` (or `accessToken` in NewAuthHandler) ever get assigned to something with a wider lifetime, logged, or passed somewhere unexpected?\n3. Check every error path in httpvendorclient.go and handlers.go for a raw vendor response body, raw dial/DNS error, or any other potentially-sensitive detail leaking into a log call, an audit event, or the HTTP response written to the connector's own caller.\n4. Is reusing api.GrantLimiter for this purpose actually sound, or does anything about GrantLimiter's original design (built for the token *issuance* endpoint, PR #30/#34) not transfer cleanly to gating *vendor calls*? E.g., does keying by AuthContext.Sub (the CALLING API CLIENT's identity, not any end-user identity) match what leaf 5 actually asks for?\n5. The rehash of the timing-floor logic — is waitForFloor actually correctly excluded from the success path and the 429/400 paths (which the PR claims are NOT part of the timing-oracle concern), and included on all three of (and only) the three named failure branches?\n6. Anything else: error handling, nullability, off-by-one, idiom, naming, doc-comment accuracy, your usual review lens.\n\nReport your findings in plain prose to Renata Cole (03 lead), as you'd normally report a review. If everything holds up, say so plainly — don't manufacture findings."

"subagent_type": "nolan-reyes",
"prompt": "Review PR #40 on github.com/wtvamp/loginid-takehome, branch feature/LT-41, for track 03-engineering-delivery, from your usual production-failure-mode lens. This implements LT-41 (Q3): the idp-connector binary's POST /auth and POST /identity handlers against a stubbed third-party vendor. Worktree at /Users/warrenthompson/Source/LoginID-worktrees/LT-41 (based on origin/main).\n\nRead 02-ai-security-architecture/connector-security.md in full (especially its attack-tree table at the bottom) and refinement/LT-41.md for the full design intent. Key points:\n- The connector's own /auth and /identity are behind their own inbound JWT check — a distinct audience (idp-connector-service) and scope (connector:identity-lookup) from api-service's profile:* scopes.\n- No real ABC/XYZ vendor exists (explicit non-goal) — cmd/idp-connector/main.go wires either a real-shaped HTTPVendorClient (if IDP_ABC_BASE_URL is configured) or a self-contained in-process StubVendorClient (the default, since no real vendor URL exists in this environment).\n- Vendor tokens are never cached/persisted by the connector (connector-security.md §1's \"caller-holds-the-token\" model) — the caller (api-service, in this project's shape) holds the vendor token between our /auth and /identity calls and presents it as a request header (X-Vendor-Access-Token) on /identity; the connector never retries a vendor call with a token it already knows is stale, on its own initiative.\n- Attack-tree leaf 5 (credential-stuffing oracle): outbound vendor calls rate-limited per calling-API-client identity AND per source IP, stricter on failure ratio than raw volume, reusing the already-built api.GrantLimiter (PR #30/#34) rather than a new component.\n- A ~100ms uniform floor on /identity's three failure branches (no token, bad/expired token, vendor rejected it) — Marcus Ilori's ruling on a timing-oracle objection, explicitly a partial mitigation (not full closure, since a real vendor round-trip's latency distribution isn't controllable).\n\nKey files (all new unless noted):\n- internal/connector/httpvendorclient.go — HTTPVendorClient: a module-level defaultVendorHTTPClient shared across every HTTPVendorClient instance that doesn't get an explicit one passed in (bounded Transport: MaxIdleConns 20, MaxIdleConnsPerHost 5, MaxConnsPerHost 10, IdleConnTimeout 30s; explicit http.Client.Timeout 10s as a backstop alongside context.WithTimeout). Authenticate/FetchIdentity build a fresh *http.Request per call.\n- internal/connector/stubvendorclient.go — in-process fake with three maps (credentials, identities, tokens) protected by one mutex; tokens never expire or get cleaned up (no TTL, no eviction) — this is explicitly a stub for a story with no real vendor, not a production component, but worth your read on whether that's clearly enough scoped/documented as such.\n- internal/connector/handlers.go — NewAuthHandler/NewIdentityHandler; a single shared api.GrantLimiter instance (constructed once in internal/app/connector_router.go) gates BOTH handlers, keyed by (AuthContext.Sub, source IP) for every vendor-call attempt regardless of which endpoint.\n- internal/app/connector_router.go — NewConnectorRouter: constructs one InProcessGrantLimiter per process (not shared across replicas — same known limitation this codebase's other rate-limiting components already accept, per PR #34's own prior review discussion).\n- cmd/idp-connector/main.go — vendor client selection logic; JWKS cache construction (15-minute TTL, matching api-service's verifier).\n\nPlease run `go build ./...`, `go vet ./...`, and `go test ./... -race` yourself in that worktree, then focus on:\n1. Production-failure-mode read on the vendor call path: if the (stubbed or real) vendor becomes slow or hangs, what actually bounds a stuck /auth or /identity request from this connector's own perspective? Is context.WithTimeout actually wired all the way through from the inbound request's context to the outbound vendor call, or could an inbound request with no deadline (or a very long one) leave a vendor call blocked far longer than the connector's own inbound NewDeadlineMiddleware would suggest is safe? Check the actual deadline budget used (deadlineBudget in internal/api/jwtmiddleware.go, if that's what NewDeadlineMiddleware applies here too) against vendorCallTimeout (10s) — do they compose sensibly, or could the deadline middleware cut a request off mid-vendor-call in a way that leaks a goroutine or otherwise misbehaves?\n2. Is the shared GrantLimiter instance across BOTH /auth and /identity a real problem or a reasonable design choice? E.g., could a caller intentionally exhaust their own backoff budget against /auth (which is comparatively low-value to attack) to deny themselves or others legitimate /identity calls, or vice versa — is that an actual production concern or an acceptable simplification given this is a single internal caller (api-service) in this project's actual topology?\n2b. Also check: does GrantLimiter's key space collide in any way that would let one legitimate caller's failures affect an unrelated caller — i.e., is AuthContext.Sub actually populated correctly and uniquely per calling client in the connector's inbound JWT flow, or could two different real callers ever share a sub value in a way that would falsely couple their rate-limit state?\n3. StubVendorClient's tokens map — no TTL, no cap on distinct tokens issued, no eviction. In a long-running process (even for demo/local purposes) is this a real unbounded-growth concern of the same shape this codebase has fixed elsewhere (TouchCounter, GrantLimiter, JWKSCache all got sweep-based eviction after review), or is it acceptably out of scope given it's explicitly a stub with no production deployment path?\n4. The 10s vendorCallTimeout plus the connector's own NewDeadlineMiddleware — walk through what happens end-to-end if the (stub or real) vendor never responds at all: does the request actually terminate cleanly within a bounded time, or is there a scenario where it hangs past what an operator watching this service would expect from the documented budgets?\n5. Anything else your pattern-matching on past production incidents flags — this is explicitly the lens you bring that a correctness-only review might miss.\n\nReport your findings in plain prose to Renata Cole (03 lead), as you'd normally report a review. Distinguish real bugs from acceptable, already-understood scope limitations that should just be named explicitly (same discipline as your LT-51/PR #34 review) — don't inflate a named limitation into a blocker."

Both directly asserted by tests.\n6. Everything else holds up.
