Adds shopspring/decimal as a require (folded with the first consuming task per
Plan 2 convention). cenkalti/backoff/v4 is also now consumed transitively;
remains indirect until Task 5 (reconnect) imports it.
Hand-crafted fixture matches spec §8.5 schema. Live API endpoint may move; client
takes BaseURL config for swap-in once api.ransomware.live publishes a stable JSON
endpoint (current free tier returns HTML landing page on /recentvictims).
Closes 36 findings from the project audit. The headline win is correctness:
the daemon now actually does what the README claims, all three audit-log
integrity layers verify, and the rotation control loop terminates.
Critical fixes:
- Orchestrator bumps Credential.last_rotated_at on success and writes a
sealed credential_versions row, so the policy evaluator stops re-firing
the same rotation every tick
- Envelope encryption (AES-256-GCM, KEK-wrapped DEK, AAD-bound) is now
wired into the rotation success path; the credential_versions table is
no longer dead schema
- cre audit verify checks all three layers (hash chain + HMAC ratchet +
Merkle batches) instead of only the chain
- BatchSealerScheduler runs every 300s and on shutdown so audit_batches
actually fills with signed Merkle roots
- Compliance bundle exports the real audit_batches list and covers
public_key.pem under the manifest's checksum
- cre run/watch hard-fail without CRE_HMAC_KEY_HEX + CRE_KEK_HEX rather
than silently using zero defaults
Quality fixes:
- HTTP::Client wrapper with connect/read timeouts + bounded retry-with-
jitter on 408/429/5xx; Telegram error logs redact the bot token
- EventBus dispatch isolates Block subscribers behind select+timeout so
one stuck subscriber can't pin the bus
- RotationWorker checks rotations.in_flight before dispatching to dedupe
duplicate schedules; PG enforces it at the DB via partial unique index
- Commit-step failures transition rotations to Inconsistent (a terminal
state) and raise a critical alert instead of pretending success
- env_file rotator uses per-PID pending paths plus an exclusive flock on
a sibling .lock file so two daemons can't race on the rename
- Versioned migration runner replaces the soup of CREATE IF NOT EXISTS;
SQLite gains BEFORE UPDATE / BEFORE DELETE triggers on audit_events
- AuditSubscriber publishes a critical alert + panics by default when
log writes fail, instead of silently dropping
- Engine.stop drains via an ack channel with a 2s deadline rather than
the previous magic 50ms sleep
- Policy DSL moved into CRE::Policy::Dsl module (consumers `include` it);
multiple matching policies raise PolicyConflictError
- Evaluator uses credentials.overdue() per-max_age group instead of
loading every credential each tick
- AuditRepo gains each_in_range streaming and all_batches enumeration;
bundle export streams instead of buffering
- New cre verify-bundle <zip> CLI re-runs every check the bundle README
documents; new cre tui-demo for synthetic event preview
Tests: 179 unit (up from 159), all passing. New rotation_worker_spec,
new SigV4 regression vector, new orchestrator success-path coverage
(envelope write + last_rotated_at bump + Inconsistent state).
Docs: README + learn/00..04 aligned with the post-audit behavior;
removed /snooze (was a stub) and the AwsIamKey/Database CredentialKind
variants that had no rotators. Added required-env-var documentation.
Update all five learn documents to match the post-audit codebase:
- Replace references to the deleted server-side X3DH/Double Ratchet (`backend/app/core/encryption/`) with their client-side TypeScript counterparts (`frontend/src/crypto/{x3dh,double-ratchet}.ts`).
- Drop mentions of the removed `RatchetState` and `SkippedMessageKey` PostgreSQL models, the server-generated key paths, and the deprecated `send_encrypted_message` server-encryption method. Add an explicit "why we deleted server-side crypto" rationale in 02-ARCHITECTURE.
- Update API endpoint listings: drop `/encryption/initialize-keys`, `/encryption/rotate-signed-prekey`, `/encryption/opk-count`; add `/auth/me`, `/auth/logout`. Note that all non-auth routes require the session cookie.
- Reflect the new schema: `IdentityKey`, `SignedPrekey`, and `OneTimePrekey` now hold only public material; `User` carries a 64-byte `webauthn_user_handle`.
- Replace the `/ws?user_id=...` example with cookie-authenticated WebSocket usage.
- Remove all line-number references throughout (per the no-line-numbers feedback) — ~300 stripped via regex pass plus targeted prose rewrites.
- Update WebAuthn copy to reflect `UserVerificationRequirement.REQUIRED`, the per-credential-backup-eligibility flag, and challenge-bytes-keyed authentication storage.
- Refresh the file index and project tree to match the trimmed module layout.
This commit applies the actionable plan from docs/plans/2026-04-29-encrypted-p2p-chat-audit-fixes.md.
Backend
- Delete server-side X3DH/Double Ratchet (`app/core/encryption/*`); the server is now an opaque relay for client-encrypted messages.
- Drop `private_key` columns from IdentityKey/SignedPrekey/OneTimePrekey; prekey-bundle endpoint serves only public material.
- Remove RatchetState and SkippedMessageKey models and the deprecated server-encryption code path in message_service.
- Fix the broken `not OneTimePrekey.is_used` SQL filter (`Column.is_(False)` instead of Python `not`); repair the silent OPK-replenish amplification by deleting the server-generated path entirely.
- Stop calling `prekey_service.initialize_user_keys` from registration/login. Server never holds private key material again.
- Add session-cookie auth: opaque token issued in Redis on register/auth complete, `current_user` dependency on every protected route, `/auth/me`, `/auth/logout`. WebSocket authenticates via the same cookie.
- Add room membership checks to WS encrypted_message + typing handlers, GET/DELETE /rooms/{id}, GET /rooms/{id}/messages. broadcast_to_room now filters by participants, not presence.
- Add slowapi rate limits to register/auth/search; per-user sliding-window cap on WS messages.
- WebAuthn: replace username with a 64-byte random `webauthn_user_handle` for `user.id`; fix `backup_eligible` to read `credential_backup_eligible`; switch UserVerificationRequirement to REQUIRED; key authentication challenges by challenge bytes (no more "discoverable" collision).
- Implement GET /rooms/{id} and DELETE /rooms/{id} (cascade delete with ownership check) and fix the N+1 in list_rooms by batching User lookups.
- Remove broken/obsolete tests; add regression tests for the OPK filter bug and session-protected endpoints (401 without cookie).
- Sanitize WebSocket error responses; correlation IDs replace stack-trace leaks.
Frontend
- X3DH: prepend the 32-byte 0xff F prefix to the HKDF input per spec section 2.2.
- Double Ratchet: switch KDF_RK to spec form (HKDF salt=root_key, IKM=dh_output) and use 0x01/0x02 byte tags for KDF_CK.
- Replace base64 helpers in `crypto/primitives.ts` with the URL-safe codec from `lib/base64.ts` (single source of truth, no spread-stack hazard).
- Update auth.service to issue a session via cookies (no more dead token store), call `/auth/me` on app boot, clear crypto state on logout. Delete unused `session.store.ts`.
- Update room.service / Chat page to drop client-supplied user_id arguments; the cookie now identifies the caller.
- Better forward-secrecy UX text for messages predating the device.
- Add Vitest with X3DH and Double Ratchet round-trip + tamper-detection tests.
Tooling
- Add `slowapi>=0.1.9` to backend deps; add `vitest` to frontend devDeps with `pnpm test` script.
- justfile: `test-frontend`, `dev-reset`.
- Adjust `.gitignore` so the Python `lib/` rules no longer hide `frontend/src/lib`.
Migration: existing dev volumes hold private-key columns and KDF-incompatible ratchet states; run `just dev-reset` and re-register before hitting the new code path.
- New module src/Aenebris/Net/IP.hs exposes
sockAddrToIPBytes :: SockAddr -> ByteString.
Single canonical implementation for IPv4 dotted-decimal, IPv6
colon-hex (8 groups), and unix-socket "unix:<path>" rendering.
- Aenebris.RateLimit.clientIPKey reduces to
`sockAddrToIPBytes . remoteHost`. Removes the local v6Bytes,
the hostAddressToTuple/hostAddress6ToTuple/printf/showHex/
intercalate imports, and the duplicated implementation.
- Aenebris.DDoS.ConnLimit drops its private copy of the same
function. ipBytesFromSockAddr is kept as a thin alias for
test backward-compatibility (= sockAddrToIPBytes), so existing
callers and the connLimitSpec test continue to compile without
rename churn.
- aenebris.cabal: expose Aenebris.Net.IP in the library stanza
(now 30 modules total).
- test/Spec.hs: new netIpSpec asserts IPv4 dotted decimal,
loopback, unix-socket prefix, and IPv6 colon-separated rendering
(8 groups → 7 colons). Wires netIpSpec into main right after
geoSpec.
362 examples passing, 0 failures, 0 GHC warnings.
- Geo.hs (Finding 14): geoAsnCounts is now bounded by
defaultGeoAsnCountCap = 200_000. capAsnCounts is called inside
bumpAsnCounter; on overflow, the entry with the oldest
awWindowStart is evicted via Data.List.minimumBy + Data.Ord.comparing.
Closes the unbounded-Map memory growth path. Uses minimumBy and
comparing imports added to the existing module.
- ML/Middleware.hs, WAF/Engine.hs, Honeypot.hs (Finding 19): em
dashes (\x2014) in user-facing response bodies and the generated
robots.txt comment replaced with ASCII hyphens, per the project's
guardrail-safe terminology rule.
- aenebris.cabal (Finding 20): copyright field updated from
'2025 Carter Perez' to '2026 AngelaMos' to match the file headers.
- ML/IForest.hs (Finding 28): pathLength now respects a hard
maxIForestDepth = 64 cutoff. Beyond that depth the function
returns currentDepth + c(1) (= currentDepth) without further
recursion, so a pathological tree built by a buggy fitter cannot
blow the stack. Standard iForest depth is ceil(log2(256)) = 8, so
the cap leaves >>8 generous headroom.
- ML/Model.hs (Finding 29): validateCategoricalNode now also
rejects categorical thresholds that are not whole numbers. A
threshold of 1.5 would silently floor to 1 today; with this
change it is reported as a clear validation error instead.
Real LightGBM never writes non-integer cat indices, so this is
defense-in-depth against malformed exporters.
Build clean, 358 examples passing, 0 failures.
