+# AML recorder fixture contract
+
+This note documents the intent and boundary behavior of the fixture recorder used for AML/KYC provider interactions.
+
+## Purpose
+
+The recorder captures request/response traces, redacts sensitive values, and writes deterministic JSON fixtures for test replay. It is intentionally scoped to test-only code paths and must not be imported into production logic.
+
+## Public contract
+
+The main exported structures are:
+
+- `RecordedRequest`: a request trace with method, path, headers, optional body, and timestamp.
+- `RecordedResponse`: a response trace with status, headers, body, and timestamp.
+- `RecordedInteraction`: a labeled pair of a request and its response.
+
+These objects are treated as structural contracts in tests and runtime validation. Invalid input is rejected with `TypeError` so failures are deterministic and easy to diagnose.
+
+## Security assumptions
+
+- Redaction runs before serialization to disk.
+- Header names and values are validated so malformed data does not quietly propagate into fixtures.
+- HTTP status values must remain within the valid 100-599 range.
+- Request paths must be non-empty and must start with `/` to avoid malformed routing traces.
+
+## State transitions
+
+The recorder remains in a simple lifecycle:
+
+1. `createRecorder` creates an empty in-memory recording session.
+2. `record()` appends a new interaction and increments the count.
+3. `flush()` writes the full fixture file and persists redaction metadata.
+4. `loadFixtures()` reads the saved JSON back for replay or assertion.
+
+This gives deterministic test behavior and keeps fixture generation easy to reason about during CI and audit reviews.

+# Issue #979 — RefreshService Failure-Path Regression Validation
+
+> Included in this PR because the CI integration token cannot edit the PR
+> description on the upstream repository (403). Reviewers: this documents the
+> exercised cases and results for the regression coverage added to
+> `src/auth/refresh/refreshService.test.ts`.
+>
+> Review location: PR #1194 (`feature/backend-011-rate-limiter-tier-policies` → `master`).
+
+## Scope
+
+Exercises the three explicit `return null` contracts in
+`src/auth/refresh/refreshService.ts` (evidence lines **67 / 77 / 97**),
+asserting observable value, log, and transaction-boundary behavior.
+The existing public contract is preserved — **no production code changed**.
+
+## Exercised cases
+
+| Branch | Test | Asserts |
+| :-- | :-- | :-- |
+| Line 67 — token verification throws | `returns null and logs the rejection reason when verifyRefreshToken throws` | null return; exact warn payload `{ error: 'jwt malformed' }`; transaction never opened; repo untouched |
+| Line 67 boundary | `returns null for empty and whitespace-only tokens` | `''` and `' '` hit the same null contract without opening a transaction |
+| Line 77 — in-flight duplicate | `returns null for a duplicate refresh while one is in flight` | null + exact `Concurrent refresh already in flight` payload; no revocation/writes by the loser; winner still completes rotation; lock released (next attempt reaches the transaction) |
+| Line 97 — session row missing | `returns null with a not-found warning when the locked session row is missing` | null + exact `Session not found during refresh` payload; transaction opened (unlike line 67); no revocation/consume/create; in-flight lock released |
+| Line 97 falsy boundary | `treats an undefined session row the same as a missing one` | falsy `undefined` row takes the identical null path as explicit `null` |
+
+Neighboring normal paths are asserted inside the same tests: successful
+rotation of the winning caller (line 77) and lock release enabling subsequent
+transactions (lines 77 / 97).
+
+## Results
+
+- Focused file: `refreshService.test.ts` — **20/20 passed**
+- Surrounding suites (`src/auth/refresh`) — **33/33 passed**;
+ `refreshService.ts` at **100% statements / branches / functions / lines**
+ (project gate ≥95%)
+- PR suites (`health.test.ts`, `rateLimit.test.ts`,
+ `startupAuthRateTierPolicy.test.ts`) — **132/132 passed**
+- Lint (`eslint src/auth/refresh/refreshService.test.ts`) — **clean**
+ (pre-existing `as any` casts in the file were removed; logger typed as `Logger`)
+- Typecheck (`tsc --noEmit`) — **no errors in changed files**
+
+## Determinism / error observability
+
+- Failure behavior is deterministic: all inputs (expired, missing, revoked,
+ consumed, duplicate, invalid) map to an explicit `null` return with a fixed
+ log message and payload shape.
+- Log assertions pin the exact message string and payload, so a regression
+ that changes the error contract (message, coercion via `String(error)`, or
+ silent swallow) fails the suite.
+- No wall-clock dependence: expiry boundaries use fixed `Date` values
+ (`NOW_FUTURE` / `NOW_PAST`); concurrency uses explicit promise gates.
+
+## Re-validation (2026-09-28, branch tip `b5c2a558`)
+
+- Focused file rerun — **20/20 passed** (`npx jest
+ src/auth/refresh/refreshService.test.ts --runInBand`)
+- Surrounding suite rerun — **33/33 passed** (`npx jest src/auth/refresh --runInBand`,
+ 4 suites)
+- Coverage rerun with the ≥95% gate enforced on `refreshService.ts` — **100%
+ statements / branches / functions / lines**, threshold met
+- Typecheck (`npx tsc --noEmit`) — **0 errors in `src/auth/refresh/**`**;
+ 247 pre-existing errors elsewhere in the repo (unrelated modules, see the
+ `isolatedModules` / `diagnostics.warnOnly` note in `jest.config.js`)
+- Lint (`npx eslint` on `refreshService.ts` + `refreshService.test.ts`) — **clean**
+- Known unrelated failure: `src/auth/register/__tests__/roundtrip.test.ts`
+ (error-message wording) — pre-existing on `master`, untouched by this branch
+- Contract checks (`npm run pact:verify`) — **13/13 passed**
+- PR-description edits via `gh pr edit 1194` return `GraphQL: Resource not
+ accessible by integration (updatePullRequest)`; PR comments likewise fail
+ with `addComment` 403, so the token's PR write surface is read-only and
+ this document is the canonical record for review. The exercised-case table
+ above is ready to paste into the PR description by a maintainer.

-# Rate Limiter Tier Policies (BE-011)
-
-## Overview
-
-Revora-Backend enforces a **multi-tier sliding-window rate limit** on the
-`POST /api/v1/startup/register` endpoint. The policy provides three tiers of
-access, each with distinct quotas, so internal infrastructure and verified
-partners are not penalised by the conservative public default while still
-providing a hard upper bound against abuse.
-
-```
- ┌────────────────────────────────────────────────────────────────────────────┐
- │ POST /api/v1/startup/register │
- │ │
- │ x-revora-rate-tier ──► resolveTier() ──► InMemoryRateLimitStore │
- │ x-revora-tier-secret │ │ │
- │ ▼ ▼ │
- │ ┌──────────┬──────────┬──────────┐ fixed-window counter │
- │ │ standard │ trusted │ internal │ per (keyPrefix + IP) │
- │ │ 5/15min │ 10/15min │ 25/15min │ │
- │ └──────────┴──────────┴──────────┘ │
- │ │ │
- │ quota OK? ────┴──► handler (201) │
- │ quota exceeded? ──► 429 + Retry-After │
- └────────────────────────────────────────────────────────────────────────────┘

-## Tiers and Limits
-
-| Tier | Request Limit | Window | Description |
-| :----------- | :------------ | :--------- | :------------------------------------------------- |
-| **standard** | 5 | 15 minutes | Default for any public IP address. |
-| **trusted** | 10 | 15 minutes | Verified external partners with a valid secret. |
-| **internal** | 25 | 15 minutes | Revora internal infrastructure and tooling. |
-
----
-
-## Implementation
-
-### Middleware: `createStartupAuthTierLimiter`
-
-Located in [`src/middleware/startupAuthRateTierPolicy.ts`](../src/middleware/startupAuthRateTierPolicy.ts).
-
-```
-/**
- * @notice Builds the startup-auth tier resolution and enforcement middleware.
- *
- * @dev Tier resolution is a two-step process:
- * 1. Read `x-revora-rate-tier` from the request header.
- * 2. Validate the shared secret in `x-revora-tier-secret` against
- * the `STARTUP_AUTH_TIER_SECRET` environment variable.
- * Any failure at step 2 silently falls back to "standard".
- *
- * @param options.store Optional custom RateLimitStore (default: InMemoryRateLimitStore).
- * @param options.tierSecretEnvName Name of the env var holding the shared secret
- * (default: "STARTUP_AUTH_TIER_SECRET").
- * @return { middleware, resolveTier, reset }
- */
-```
-
-The returned `middleware` is mounted directly on the route:
-
-```typescript
-const startupTierLimiter = createStartupAuthTierLimiter();
-
-apiRouter.post(
- "/startup/register",
- startupTierLimiter.middleware,
- createStartupRegisterHandler(),
-);
-```
-
-### Core Rate Limit Engine: `createRateLimitMiddleware`
-
-Located in [`src/middleware/rateLimit.ts`](../src/middleware/rateLimit.ts).
-
-```
-/**
- * @notice Fixed-window rate-limit middleware.
- *
- * @dev Window is keyed by `keyPrefix + ":" + "ip:" + req.ip`.
- * Counters are stored in InMemoryRateLimitStore (process-local).
- * On every request the middleware sets:
- * X-RateLimit-Limit — configured maximum
- * X-RateLimit-Remaining — remaining in the current window (≥ 0)
- * X-RateLimit-Reset — UTC epoch seconds when the window resets
- * On breach:
- * Retry-After — seconds until the window resets
- * 429 Too Many Requests — JSON body with error message
- */
-```

-
-## Request Headers
-
-| Header | Required for tier | Description |
-| :----------------------- | :----------------- | :----------------------------------------------------- |
-| `x-revora-rate-tier` | `trusted`, `internal` | Requested tier (`standard`, `trusted`, or `internal`). |
-| `x-revora-tier-secret` | `trusted`, `internal` | Shared secret authenticating the elevated tier. |
-
-### Tier Resolution Logic (pseudocode)
-
-```
-resolveTier(req):
- tier ← lowercase(header("x-revora-rate-tier")) or ""
- if tier not in ["trusted", "internal"]:
- return "standard"
- secret ← env("STARTUP_AUTH_TIER_SECRET").trim()
- provided ← header("x-revora-tier-secret").trim()
- if secret is empty or provided ≠ secret:
- return "standard" ← fail-safe downgrade, no error revealed
- return tier
-```
-
----
-
-## Response Headers
-
-These headers are set on **every** request, including those that are blocked:
-
-| Header | Value |
-| :-------------------- | :------------------------------------------------------------ |
-| `X-RateLimit-Limit` | Maximum requests allowed in the window for the resolved tier. |
-| `X-RateLimit-Remaining` | Requests remaining (never negative). |
-| `X-RateLimit-Reset` | UTC epoch seconds when the window resets. |
-| `X-RateLimit-Tier` | The resolved tier name (`standard`, `trusted`, `internal`). |
-| `Retry-After` | Seconds to wait (**only on 429 responses**). |
-
-### 429 Response Body
-
-```json
-{
- "code": "TOO_MANY_REQUESTS",
- "message": "Too many registration attempts, please try again after 15 minutes.",
- "details": { "retryAfter": 1234567890 }
-}
-```
-
----
-
-## Security Assumptions
-
-1. **Identity Assertion**: Tier elevation is gated solely on the `x-revora-tier-secret`
- header. This is a **shared secret** pattern — it is not a substitute for
- request-level authentication. Protect the secret with the same care as a
- signing key.
-
-2. **Fail-Safe Downgrade**: An absent, empty, or mismatched secret always results
- in `standard` tier resolution. The server never returns an error that
- distinguishes "wrong secret" from "no secret", preventing oracle attacks.
-
-3. **IP-Based Tracking**: Rate limits are tracked per resolved client IP
- (`req.ip`, with `trust proxy = 1`). Ensure the Express app is configured
- correctly behind a load-balancer so `req.ip` reflects the real client IP.
- A misconfigured proxy could allow a single client to appear as many IPs,
- bypassing the limit.
-
-4. **In-Memory Store**: The current `InMemoryRateLimitStore` is **process-local**.
- In a multi-instance deployment, counters are not shared between instances,
- so effective limits are `numInstances × limit`. Replace the store with a
- Redis-backed implementation (using `INCR`/`EXPIRE`) before horizontal scale-out.
-
-5. **Secret Rotation**: Rotating `STARTUP_AUTH_TIER_SECRET` requires a
- coordinated rolling deploy. During the rotation window, requests with the
- old secret will be downgraded to `standard`; plan accordingly.
-
-6. **No Per-User Isolation**: The limiter keys by IP, not by user identity.
- Authenticated user IDs should be layered on top if per-account isolation is
- required in future tiers.
-

-## Abuse and Failure Paths
-
-### Abuse scenarios
-
-| Scenario | Behaviour | Mitigation |
-| :------- | :-------- | :--------- |
-| Attacker sends `x-revora-rate-tier: trusted` with a wrong secret | Downgraded to `standard` and exhausts the standard counter | No tier privilege gained; attacker burns their own quota |
-| Attacker rotates through multiple IPs to bypass per-IP limit | Each IP gets its own counter; limit applies per IP | Deploy a WAF / IP reputation list upstream for volumetric attacks |
-| Attacker guesses the tier secret by brute-force | Every attempt consumes a standard-tier slot; 5 guesses per 15 min per IP | Keep the secret ≥ 32 random bytes; rotate periodically |
-| Attacker floods with `x-revora-rate-tier: standard` | Exhausts their IP quota after 5 requests | Same as no tier header — intended behaviour |
-| Unknown tier value (e.g. `vip`) | Treated as `standard` | Silently downgraded; no error revealed |
-
-### Failure scenarios
-
-| Failure | Behaviour |
-| :------- | :-------- |
-| `STARTUP_AUTH_TIER_SECRET` env var not set | All elevated tier requests fall back to `standard` (safe default) |
-| Process restart | In-memory counters reset; brief window where a fresh burst is possible during rolling deploy |
-| Store `increment()` throws unexpectedly | Uncaught exception propagates to Express error handler → 500 |
-| Upstream load balancer strips custom headers | `x-revora-rate-tier` absent → `standard` tier (safe) |
-
----
-
-## Environment Variables
-
-| Variable | Required | Description |
-| :------------------------ | :------- | :------------------------------------------------------------- |
-| `STARTUP_AUTH_TIER_SECRET` | No | Shared secret for `trusted`/`internal` tier elevation. Absent = all requests treated as `standard`. |
-
----
-
-## Deployment Checklist
-
-- [ ] Set `STARTUP_AUTH_TIER_SECRET` in the deployment secrets store (not in `.env` committed to VCS).
-- [ ] Configure `app.set('trust proxy', 1)` (already done in `createApp`).
-- [ ] For multi-instance deployments: swap `InMemoryRateLimitStore` for a Redis-backed store.
-- [ ] Rotate `STARTUP_AUTH_TIER_SECRET` at least once per quarter.
-- [ ] Add WAF-level IP rate limiting upstream for large-scale volumetric attack mitigation.
-

- Policies (BE-011)` describe block covers all three tiers, header presence,
- downgrade on wrong/absent secret, quota boundary conditions, cross-tier
- counter isolation, health-endpoint isolation, and 429 body format.
-
-- **Core rate-limit engine tests**:
- [`src/middleware/rateLimit.test.ts`](../src/middleware/rateLimit.test.ts)
- — 380 lines, covers `InMemoryRateLimitStore` lifecycle, per-IP and per-user

+# Social anti-enumeration metrics — failure-handling regression coverage
+
+**Issue:** [#1060](https://github.com/RevoraOrg/Revora-Backend/issues/1060) — regression coverage for
+`getSocialAntiEnumerationMetrics` failure handling.
+**Relationship to #1027:** this PR is the successor deliverable to the earlier
+`fix/1027-user-failure-handling-regression` branch. Issue #1027 targets a different module
+(`UserRepository`) and is **not** closed by this PR.
+**Change type:** **test-only.** No production source file is modified by this PR — the diff is one new
+test file plus one `package.json` script and this document.
+
+| Artifact | Path |
+| --- | --- |
+| Code under test | `src/middleware/socialAntiEnumerationMiddleware.ts` (unchanged) |
+| New regression suite | `src/middleware/socialAntiEnumerationMiddleware.regression.test.ts` (new) |
+| Existing suite (untouched) | `src/middleware/socialAntiEnumerationMiddleware.test.ts` |
+| Convenience script | `npm run test:coverage:social-anti-enum` |
+
+`git status --short` on this branch lists only the new `*.regression.test.ts` under `src/`, and
+`git diff origin/master -- src/middleware/socialAntiEnumerationMiddleware.ts` is empty: the middleware is
+pinned, not patched.
+
+---
+
+## 1. Why this suite exists
+
+`socialAntiEnumerationMiddleware` is the only guard that stands between an unauthenticated social
+login request and per-subject rate limiting. Its security value rests on three inline guards inside
+`extractProviderSub`, each of which returns `null` (the "unidentifiable request" signal) and therefore
+decides whether a request is limited **per token subject** or falls back to the looser **per-IP**
+bucket:
+
+| # | Guard | Source line | If it silently changes |
+| --- | --- | --- | --- |
+| G1 | `if (!VALID_PROVIDERS.has(provider as SocialAuthProvider)) return null;` | 90 | Any provider string (including attacker-chosen values) becomes a limiter bucket key |
+| G2 | `if (typeof idToken !== 'string') return null;` | 91 | Non-string bodies reach `String.prototype.split` — throws (500) or coerces to a shared bucket |
+| G3 | `if (parts.length !== 3) return null;` | 94 | Structure-less strings get parsed as JWTs, so crafted input can forge a subject |
+
+The pre-existing suite asserted the happy path and a few adjacent behaviours, but nothing pinned the
+observable contract that the metrics consumers depend on:
+
+```ts
+export function getSocialAntiEnumerationMetrics(): { attempts: number; rejections: number }
+```
+
+Specifically, before this PR there was no test that would fail if:
+
+1. a rejection on the **per-provider-sub** branch stopped being counted, or stopped advancing only once;
+2. a rejection on the **IP-fallback** branch was double-counted (or not counted at all);
+3. `next()` route/request signals (`next('route')`, `next('router')`, `next()`) were misread as
+ rejections — an easy over-count when the wrapper is refactored;
+4. `attempts` drifted away from "one increment per request" (e.g. only counting *identifiable*
+ requests), which would silently deflate the enumeration-rate signal that alerting is built on;
+5. the metrics snapshot stopped being a fresh, process-wide-shared object (two middleware instances
+ with different stores must feed one counter pair);
+6. a failed store threw out of the middleware instead of degrading to "attempt counted, no rejection";
+7. the guard wiring regressed so that `req.socialProviderSub` leaked to downstream handlers, or the
+ 429 body started echoing the submitted token/subject/provider.
+
+This suite pins all seven.
+
+---
+
+## 2. Contract pinned by this suite
+
+### 2.1 Extraction contract (`extractProviderSub`)
+
+* **Provider allow-list only.** Only exact, allow-listed provider strings (`google`, `github`) are
+ accepted. Case variants (`Google`, `GITHUB`), padded/whitespace variants, `null`, numbers, objects
+ and the empty string all return `null`. The gate does **not** case-fold or trim — a soft comparison
+ would create duplicate buckets (`google` vs `Google`) and double an attacker's budget.
+* **Subject boundaries.** A `sub` that is missing, not a string, or an empty/whitespace-only string
+ yields `null`. Strings up to 5000 chars are accepted verbatim (no truncation, no re-encoding),
+ including unicode. `__proto__` and duplicate JSON keys produce plain data values — never prototype
+ mutation.
+* **Payload hostile shapes.** Non-object payloads (`null`, `"string"`, `42`, `[]`) are rejected;
+ malformed base64url and invalid JSON are swallowed by the internal `try/catch` and surface as
+ `null`, never as a thrown error.
+* **Exactly three segments.** A token with a parseable payload is still rejected when it has 2, 4 or
+ 5 segments, or a trailing dot. (These cases are the payload-valid variants that a loosened
+ `parts.length` check would otherwise let through — see mutation M3 in §5.)
+
+### 2.2 Middleware contract
+
+* Every invocation increments `attempts` **exactly once**, whether or not the request was
+ identifiable, and whether or not a limiter later rejected it.
+* A rejection increments `rejections` exactly once and is attributed to the branch that produced it
+ (per-sub or IP fallback).
+* `rejections <= attempts` always holds, including after interleaved mixed sequences.
+* `next()` is called exactly once per request with the argument it received — `next()`,
+ `next(undefined)`, `next(null)`, `next('route')` and `next('router')` are **not** rejections; any
+ other non-nullish argument (`Error` instances, arbitrary strings/objects) **is** one. The same
+ matrix holds on both branches.
+* `req.socialProviderSub` is attached **only** when a subject was extracted, and the 429 response
+ reuses the configured generic message without echoing the token, subject or provider.
+* A store that throws does not take the request down: the attempt is still counted, no rejection is
+ recorded, and the failure propagates to `next(err)` for the upstream error handler.
+* Reset helpers affect only the limiter store, never the metrics pair.
+* Wiring defaults: `limit = 10`, `windowMs = 900000` (15 min), `ipFallbackLimit = 20`,
+ `keyPrefix = 'social-anti-enum:sub' | 'social-anti-enum:ip'`, shared `store` — and an omitted
+ options object falls back to those documented defaults.
+
+---
+
+## 3. Test inventory
+
+Eight `describe` blocks, **77 tests** (`109` including the pre-existing suite, which runs in the same
+gate):
+
+| Describe block | Starts at | What it pins |
+| --- | --- | --- |
+| `extractProviderSub — provider gate (line 90)` | `130` | G1: allow-list only, case variants, whitespace/padding, empty & absent `:provider` param, `__proto__`/object providers, no invented fallback key |
+| `extractProviderSub — idToken type gate (line 91)` | `179` | G2: `null`/`undefined`, numbers/booleans, objects/arrays, typed arrays, whitespace-only strings |
+| `extractProviderSub — structure gate (line 94)` | `229` | G3: 1/2/4/5-segment tokens, trailing dot, unparseable payloads, **payload-valid multi-segment tokens** |
+| `extractProviderSub — sub boundaries and hostile payloads` | `301` | `sub` type/size boundaries (5000 chars), unicode, `__proto__` & duplicate keys, `null`/string/number/array payloads (no prototype pollution, no throws) |
+| `getSocialAntiEnumerationMetrics — snapshot contract` | `364` | fresh object per call, store-independence, process-wide sharing across instances, `rejections <= attempts` |
+| `metrics — accounting when provider/sub extraction fails` | `422` | one `attempts` per request; exactly one `rejections` per rejected request on both branches; mixed-sequence alignment; reset independence; failing store degrades without throwing |
+| `extraction failure — routing, rate limiting and leakage` | `549` | unidentifiable requests are limited per IP; `req.socialProviderSub` is never attached; the 429 body leaks no token/sub/provider |
+| `middleware wiring — limiter options and next() accounting` | `657` | limiter options & defaults, shared store, `next()` route/request-signal matrix on both branches, default delegation to the real limiter factory |
+
+### 3.1 How the suite stays honest
+
+* **No production change.** The suite observes the module only through its exported surface
+ (`extractProviderSub`, `getSocialAntiEnumerationMetrics`, `createSocialAntiEnumerationMiddleware`,
+ `createSocialAntiEnumerationMiddlewareWithStore`, the reset helpers).
+* **Limiter interception without mocking behaviour away.** `jest.mock('./rateLimit', factory)` is used
+ with a factory that **delegates to `jest.requireActual`** by default, so every suite except the
+ wiring one exercises the real limiter. Only the wiring suite swaps in a capturing implementation
+ (to read the limiter options and to drive `next()` with arbitrary arguments) and restores the
+ delegate in `afterEach`. A `jest.spyOn` approach was tried first and abandoned: the spy did not
+ reach the call site because the middleware captures the factory at import time.
+* **Fresh store per request** (`InMemoryRateLimitStore`) so windows never leak between assertions,
+ while the metrics pair is deliberately **process-wide** and asserted as such.
+* **Assertions are on observable output**, not internals: `next()` arguments, response status/body,
+ headers, and the metrics snapshot.
+
+---
+
+## 4. Gates and evidence
+
+All commands were run from the repo root on the branch tip (`fix/1060-social-anti-enumeration-regression`).
+
+| Gate | Command | Result |
+| --- | --- | --- |

+
+A repo-wide `npx jest --ci --silent` run on the branch tip reports **39 failing suites**, none of them
+touched by this PR. Representative causes, quoted from that run:
+
+* `src/routes/health.test.ts` — `dependency graph security › exposes only safe Stellar metadata without
+ leaking upstream details`: `expect(response.body.checks[1].details.url).toBeDefined()` receives
+ `undefined`.
+* `src/services/__tests__/distributionScheduler.test.ts` — `ReferenceError:
+ AdvisoryLockNotAvailableError is not defined` (`distributionScheduler.ts:846`).
+* `src/services/fxConversionEngine.test.ts` — bucket rounding mismatch (`Expected: "1.25"`).
+* `src/routes/compliance.test.ts` — role/403 expectation mismatch.
+* The remainder are DB-/Redis-backed integration suites (`src/db/**`, `src/routes/**`,
+ `src/__tests__/chaos/**`, `e2e-happy-path`, `openapi*`) that need services this workstation does not
+ run.

+
+**Why these cannot be caused by this PR.** `git diff --stat origin/master` for this branch lists only
+an added test file, one `package.json` script and this document — **no production module is modified**,
+and nothing in the repository imports the added test file. Jest gives every test file its own module
+registry, so those suites execute byte-identical code with and without this PR.
+
+**Spot-check (empirical).** A pristine `origin/master` worktree (detached at `2995ef41`, removed
+afterwards) was used to run three sampled failing suites
+(`src/services/fxConversionEngine.test.ts`, `src/routes/compliance.test.ts`,
+`src/services/__tests__/sanctionsListDiffService.test.ts`) side by side with the branch tip:
+
+| Tree | Result |
+| --- | --- |
+| Branch tip (this PR applied) | `Test Suites: 3 failed, 3 total` / `Tests: 40 failed, 145 passed, 185 total` |
+| Pristine `origin/master` (`2995ef41`) | `Test Suites: 3 failed, 3 total` / `Tests: 40 failed, 145 passed, 185 total` |
+
+Identical failure counts on both trees — the failures are pre-existing and unrelated.
+
+
+
+---
+
+## 5. Mutation results (do the tests actually bite?)
+
+Seven source mutants were applied in turn to `src/middleware/socialAntiEnumerationMiddleware.ts` and
+the regression suite re-run. Every mutant was killed; the file was restored between mutants (verified
+with `git diff --stat src/middleware/socialAntiEnumerationMiddleware.ts` → empty).
+
+| ID | Line | Mutation | Outcome | First tests that fail |
+| --- | --- | --- | --- | --- |
+| M1 | 90 | provider allow-list gate disabled (`if (false)`) | **killed** — 10 failed / 77 | provider gate: unsupported provider, case variants, whitespace/padding, empty provider |
+| M2 | 91 | `typeof idToken !== 'string'` gate disabled | **killed** — 6 failed / 77 | type gate: `null`/`undefined`, numeric/boolean, object/array, typed-array tokens |
+| M3 | 94 | `parts.length !== 3` loosened to `parts.length === 0` | **killed** — 4 failed / 77 | structure gate: 2-segment, 4-segment, 5-segment, trailing-dot tokens (all with a *parseable* payload) |
+| M4 | 202 | attempt counter no longer incremented | **killed** — 22 failed / 77 | snapshot contract (process-wide sharing, `rejections <= attempts`), attempts accounting |
+| M5 | 217 | per-sub rejection no longer counted | **killed** — 9 failed / 77 | per-sub rejection accounting, mixed-sequence alignment, `rejections <= attempts` |
+| M6 | 58 | snapshot hardcodes `attempts: 0` | **killed** — 22 failed / 77 | snapshot contract, attempts accounting |
+| M7 | `ipFallbackLimit` default | `20` → `10` | **killed** — 2 failed / 77 | wiring defaults, omitted-options defaults |
+
+M3 is the reason §2.1 lists the "payload-valid multi-segment" cases explicitly: a plausible loosening of
+the segment check survives if the only extra-segment fixtures have an unparseable middle segment (the
+JSON parse then returns `null` for the wrong reason). The suite therefore uses fixtures whose segment 2
+is a valid `{"sub": …}` payload, so only the real gate can reject them.
+
+---
+
+## 6. Security notes and abuse paths
+
+* **Enumeration oracle.** `attempts` is the numerator alerting uses. It must count *unidentifiable*
+ requests too, otherwise a client that strips the provider/`idToken` shape flies under the metric while
+ still probing the login endpoint (M4 covers this).
+* **Bucket forgery.** G1 is exact-match only: no case folding, no trimming. `Google`, `GITHUB ` and
+ `__proto__` never become subjects (prototype keys would otherwise land in a lookup table/keyed store).
+* **Token reflection.** The rejection body reuses the configured generic message
+ (`Too many requests, please try again later.`). Tests assert the 429 body contains no `sub`, no token,
+ no provider.
+* **Route/request signals are not rejections.** `next('route')` / `next('router')` mean "try the next
+ handler", not "client rejected". Treating them as rejections would inflate alerting and (via
+ downstream handlers) mis-attribute rate-limit pressure; the matrix in §2.2 is asserted on **both**
+ limiter branches.
+* **Failure is soft, not fatal.** A throwing store must not 500 the login route or silently drop the
+ attempt: the attempt is counted, no rejection is recorded, and the error is forwarded to `next(err)`.
+* **No state bleed.** Resetting the limiter store does not reset the process-wide metrics pair (the
+ opposite regression would let an attacker clear the counter), and each request uses a fresh store in
+ tests so window boundaries never mask an accounting bug.
+* **PII-free instrumentation.** `sub` values are used only to derive a limiter key; the suite asserts
+ `req.socialProviderSub` exists only for identifiable requests and that it is never attached to
+ unidentifiable ones (a leak would let a downstream handler log/enumerate subjects).
+
+---
+
+## 7. Known limitations and follow-ups
+
+* **Metrics are process-local.** `attempts`/`rejections` live in module state, so multi-replica
+ deployments need aggregation at scrape time. The suite pins the in-process contract only.
+* **No clock manipulation.** Tests rely on fresh stores/windows rather than `jest.useFakeTimers()`, so
+ window *expiry* semantics stay covered by `rateLimit.test.ts` (which exercises the store directly).
+* **Repo CI does not run on this branch.** `.github/workflows/ci.yml` and `rbac-policy-diff.yml` filter
+ `on.pull_request.branches: ["main"]`, but the default branch is `master`, so the `audit` and
+ `alert-mappings` jobs never execute for PRs against `master`. Fixing that workflow filter is a
+ separate, repo-scoped change (out of scope for a test-only PR, and it would also need to add a test
+ step, which CI currently does not have). The gates in §4 were therefore run locally.
+* **Repo-wide lint is red on `origin/master`.** `npm run lint` reports 2257 errors / 8 warnings across
+ the existing tree; this PR adds none (the new file does not appear in the report). No file is
+ auto-fixed here — that would flood the diff.
+* **Relationship to #1027.** The earlier `fix/1027-user-failure-handling-regression` branch was the
+ previous deliverable in this workspace; it targets `UserRepository` failure handling, not social
+ anti-enumeration, so it is deliberately left untouched here (and #1027 is not closed by this PR).

+/**
+ * @file src/auth/login/sessionRepositoryAdapter.test.ts
+ * @description Focused behavior coverage for `SessionRepositoryAdapter`.
+ *
+ * Contract under test (see `src/auth/login/sessionRepositoryAdapter.ts`):
+ * 1. The adapter is a pure pass-through: it maps the login module's
+ * camelCase `SessionRepository.createSession` input onto the DB
+ * repository's snake_case `CreateSessionInput`.
+ * 2. It resolves to `void` — the persisted `Session` row returned by the DB
+ * layer is intentionally discarded so callers cannot couple to row shape.
+ * 3. Errors from the DB layer propagate unchanged (no swallowing, no
+ * re-wrapping), which keeps failure modes observable and deterministic.
+ * 4. The adapter performs no validation/normalization of its own: that
+ * responsibility stays with the DB repository (and ultimately the
+ * database constraints), so a fuzz/abuse payload is forwarded verbatim.
+ *
+ * All DB access is mocked — these tests never touch Postgres.

+/**
+ * @file src/auth/login/userRepositoryAdapter.test.ts
+ * @description Regression suite for `UserRepositoryAdapter.findByEmail`.
+ *
+ * Issue #970 — the adapter contains an explicit empty-result branch
+ * (`if (!user) return null;`) that is the contract boundary between
+ * "no such account" and "the login flow may proceed". These tests pin
+ * that branch down so it cannot be changed silently.
+ *
+ * Security invariants verified here:
+ * - **Empty result is a hard `null`, never a partially-populated record.**
+ * A regression that returned `{}`, `undefined`, or swallowed the miss
+ * would let `LoginService` proceed to `verifyPassword` with
+ * `passwordHash === undefined` and potentially authenticate a
+ * non-existent user.
+ * - **Upstream errors are never converted into `null`.** A `catch` that
+ * returned `null` would turn a database outage (HTTP 500) into a
+ * credential failure (HTTP 401), hiding an incident and disabling
+ * alerting on the auth path.
+ * - **The adapter narrows, it does not forward.** Only `id`, `email`,
+ * `role` and `passwordHash` are surfaced; every other column of the
+ * `users` row (`name`, `kyc_risk_tier`, `last_oidc_groups`, timestamps)
+ * is dropped so it cannot leak into a login response body.
+ * - **No client-side input filtering.** Every value — including empty
+ * strings, whitespace and non-string input — is delegated verbatim to
+ * the repository as a *bound parameter*. Validation and normalisation
+ * live in one place; a guard clause here would create a second,
+ * divergent normalisation path.

+/**
+ * Dedicated regression suite for JwksCacheService failure handling.
+ *
+ * The consolidated `src/auth/oidc/oidc.test.ts` exercises this service through
+ * the adapter, so several of the cache's own control-flow guards are never
+ * reached there. This file targets exactly those:
+ *
+ * - the **TTL guard** — a cached entry is reused up to and including
+ * `JWKS_TTL_MS`, and re-fetched one millisecond past it,
+ * - **issuer propagation** — `issuer ?? entry?.issuer` on the first fetch, the
+ * cached issuer being inherited when a later call omits it, and a fresh
+ * issuer being accepted when the cached entry has none,
+ * - **metrics wiring** — `setGauge` fires only when an issuer is known, with the
+ * documented name/labels/help, and an injected collector overrides the global,
+ * - **in-flight bookkeeping** — a rejected refresh must clear the shared promise
+ * so the next call retries instead of resurrecting the failure,
+ * - **cache age** — `0` for an unknown issuer and the `Math.max(0, …)` clamp,
+ * - **malformed upstream payloads** — no `keys` field, a non-JSON body, an empty
+ * key set, a missing `kid`, and duplicate `kid`s.
+ *
+ * `Date.now` is overridden per test rather than faked, so the TTL boundary can be
+ * probed exactly.

+/**
+ * Dedicated test suite for `src/auth/register/types.ts`.
+ *
+ * ── Nature of the module ─────────────────────────────────────────────
+ * `types.ts` is a PURE compile-time type-declaration module. Every export is
+ * type-only:
+ *
+ * - `UserRole` : a string-literal union ('startup' | 'investor')
+ * - `RegisteredUser` : an interface (shape only)
+ * - `IUserRepository` : an interface (shape only)
+ * - `RegisterRequestBody` : an interface (shape only)
+ * - `RegisterSuccessResponse`: an interface (shape only)
+ *
+ * There is no runtime code in the file, so there is nothing to "execute"
+ * against these exports directly. To give the public contract real regression
+ * protection without changing it, coverage is split across two layers:
+ *
+ * (A) Type-level assertions validated by `tsc --noEmit` (see "Type-level
+ * contract"). Because the repo has no dedicated type-test tooling
+ * (vitest `expectTypeOf`, `tsd`, etc.), these use the standard `satisfies`
+ * operator and `// @ts-expect-error` directives. Each directive suppresses
+ * a *real* compile error today; if the type ever loosens (e.g. a new role
+ * is added, a field is dropped/made optional), `tsc` fails with an
+ * "Unused '@ts-expect-error' directive" or a missing/ excess-property
+ * error, catching the regression.
+ *
+ * NOTE: `jest` is configured with `ts-jest` `isolatedModules: true` and
+ * `diagnostics.warnOnly`, so jest does NOT type-check. The type-level
+ * assertions are intentionally runtime no-ops (their locals are referenced
+ * so the test is registered) and are only asserted by the type-check step.
+ *
+ * (B) A runtime in-memory implementation of `IUserRepository` that exercises
+ * the contract semantics the registration service actually depends on —
+ * `findByEmail` hit/miss (the duplicate-detection signal) and the
+ * `createUser` return shape and input contract.
+ *
+ * ── State transitions ────────────────────────────────────────────────
+ * `types.ts` declares no state of its own. The only state transition that
+ * touches these types is in `registerService.ts`
+ * (`unregistered → registered user, role = 'investor'`), already covered by
+ * `registerService.test.ts` and `__tests__/roundtrip.test.ts`. This file pins
+ * the contract *those* transitions rely on (notably that `createUser` accepts
+ * only the literal `role: 'investor'`) rather than fabricating a transition.
+ *
+ * ── Determinism ─────────────────────────────────────────────────────
+ * All fixtures use fixed strings, deterministic IDs (`user-N`), and a fixed
+ * `created_at` `Date`. No real time, randomness, network, or database is used.

+ * The handlers are the HTTP boundary of the Google/Apple social auth flow
+ * (login / link / unlink). These tests pin down the contract they expose to
+ * callers:
+ * - provider and body validation happens **before** the service is invoked,
+ * so malformed requests cannot reach the verifier or the database;
+ * - every `SocialAuthError` code keeps its documented HTTP status;
+ * - non-`SocialAuthError` rejections are forwarded to `next()` (the error
+ * middleware) instead of being swallowed or answered with a 500 body;
+ * - the success payloads stay exactly as the route contract advertises.

+ * Covers:
+ * - SocialAuthProvider: valid values, exhaustive union, type narrowing
+ * - SocialProviderClaims: required fields, optional isPrivateRelay, field types
+ * - SocialTokenVerifier: contract verification via fake implementations,

+ * - SocialIdentityRecord: field contract, default isPrivateRelay semantics
+ * - SocialIdentityRepository: CRUD contract via fake implementation
+ * - SocialUserRecord / SocialUserRepository: lookup contract
+ * - SocialAuthErrorCode: exhaustive set, no unknown codes accepted at compile time
+ * - SocialAuthError: construction, `code`, `message`, `name`, prototype chain,
+ * instanceof checks across serialization boundaries, all valid error codes
+ * - SocialLinkResult / SocialUnlinkResult: shape contract
+ * - SocialLoginResult: structural compatibility with LoginSuccessResponse

+ * Covers:
+ * - AlertSeverity — all four values, valid/invalid usage, tags embedding
+ * - AlertType — all eleven values, valid/invalid usage, interaction with MigrationAlert
+ * - MigrationAlert — construction contract, required/optional fields, valid combinations,
+ * invalid inputs where the runtime enforces them, boundary values, and primary state
+ * transitions (create → unresolved → resolved)
+ *
+ * Security / determinism notes:
+ * - Fake timers (jest.useFakeTimers) prevent setInterval leaks from startMonitoring().
+ * - All DB interactions are handled via createMockPool() – no real DB required.
+ * - InMemory repositories are used throughout (same pattern as migrationSafety.test.ts).

+/**
+ * Regression coverage for the explicit failure / empty-result branches of
+ * `DistributionRepository` (src/db/repositories/distributionRepository.ts).
+ *
+ * The sibling `distributionRepository.test.ts` exercises only the happy paths.
+ * These tests pin the three branches named in the issue:
+ *
+ * - `createDistributionRun` → `throw new Error('Failed to create distribution run')`
+ * when the INSERT returns zero rows,
+ * - `createPayout` → `throw new Error('Failed to create payout')`
+ * when the INSERT returns zero rows,
+ * - `findRunByParams` → `return null` when the idempotency lookup matches nothing,
+ *
+ * plus the neighbouring normal paths (transaction-client seam, mapper coercion of
+ * nullable columns) and the boundary inputs that decide the bound SQL parameters,
+ * so a silent behaviour change in any of them fails loudly here.

+ * cannot prove the two guarantees #728 actually asks for:
+ *
+ * 1. "Checkpoint stored in Postgres, not memory" — durability has to be shown

+ * 2. "Crash mid-batch resumes without duplicating outputs" — depends on
+ * `FOR UPDATE SKIP LOCKED` and a real clock, neither of which an in-memory
+ * double can model.
+ *
+ * These tests run against a real PostgreSQL container using the schema from
+ * `db/migrations/037_create_pdf_render_jobs.sql`.
+ *
+ * Requires a container runtime. If none is available the suite is skipped
+ * rather than failed, so a Docker-less developer machine stays green while CI

+ * - `transaction.integration.example.ts:114` "Offering is not active"
+ * - `transaction.integration.example.ts:215` "Offering not found"

+ * Regression suite for src/middleware/idempotency.ts line 288 — Closes #1056
+ *
+ * Evidence: `toHeaderString()` at line 288 contains an explicit `return undefined`
+ * branch for inputs that are neither a plain string nor a non-empty array.
+ * This branch feeds directly into the `contentType` field of the stored
+ * `IdempotencyRecord`, so a silent change here (e.g. returning `null` or `''`
+ * instead of `undefined`) would corrupt cached response replay across every
+ * consumer of the middleware.
+ *
+ * Coverage matrix
+ * ───────────────
+ * toHeaderString (tested via res.getHeader('content-type') → contentType field)
+ * ❶ undefined path — no Content-Type header → record.contentType is undefined
+ * ❷ string path — string header → record.contentType is that string
+ * ❸ array path — array header [v] → record.contentType is String(v[0])
+ * ❹ empty array — [] → record.contentType is undefined
+ *
+ * Neighbouring success / failure paths
+ * • Normal POST stores a response and replays it correctly (success path)
+ * • 5xx is never stored; key is released (failure/empty-result path)
+ * • PATCH is covered by the configured methods set (boundary)
+ *
+ * Boundary inputs for IdempotencyRecord fields
+ * • status 0 (never set by route) doesn't appear in stored records
+ * • Empty body string is stored as '' not undefined
+ * • Buffer body is serialised to UTF-8 string (serializeBody boundary)
+ * • undefined body (res.send(undefined)) is serialised to ''

+/**
+ * @file socialAntiEnumerationMiddleware.regression.test.ts
+ *
+ * Regression suite for issue #1060 — pins the failure handling of
+ * `getSocialAntiEnumerationMetrics()` and the extraction guards whose failures it
+ * reports on.
+ *
+ * The issue names three explicit failure exits in
+ * `src/middleware/socialAntiEnumerationMiddleware.ts`:
+ *
+ * :90 `if (!VALID_PROVIDERS.has(provider as SocialAuthProvider)) return null;`
+ * :91 `if (typeof idToken !== 'string') return null;`
+ * :94 `if (parts.length !== 3) return null;`
+ *
+ * Each of them means "we could not identify the caller from the unverified token",
+ * which routes the request to the **IP-fallback** guard instead of the
+ * per-provider-sub guard. That routing is what keeps the metrics honest:
+ *
+ * - `attempts` must climb for *every* request, including malformed ones, so an
+ * enumeration spike cannot be hidden behind unparseable tokens.
+ * - `rejections` must climb exactly once per actual limiter refusal, and never
+ * for an Express control-flow signal (`next('route')` / `next('router')`).
+ *
+ * The suite is deliberately test-only: `socialAntiEnumerationMiddleware.ts` is not
+ * modified, so the existing public contract is pinned rather than redefined.

+ * (`src/offerings/offeringRoute.ts`, Issue #1062).
+ *
+ * The module is a factory that, for each call, wires three repositories onto the
+ * supplied `pg` pool, builds an `OfferingService`, wraps it in an
+ * `OfferingHandler`, and exposes two read routes. This suite pins the factory
+ * contract (repository/service construction order and the exact routes) and
+ * drives the routes end to end through `supertest` against the real
+ * `OfferingHandler`, so the zod query validation and the `next(error)` failure
+ * paths are exercised rather than stubbed.
+ *
+ * Only the data layer (repositories + service) is doubled; no database or
+ * network is touched.
