Encryption infrastructure notes +## 2. Encryption / sessions design notes -- **Module:** `crates/shared/src/crypto.rs` (`picloud_shared::crypto`). -- **Master-key sourcing** (`MasterKey::from_env` → `resolve`): - - `PICLOUD_SECRET_KEY` = base64 of exactly 32 bytes. Missing → - `MasterKeyError::Missing` (fatal); non-base64 → `Malformed`; wrong - length → `WrongLength`. **Sourced in `main.rs::run_server` before any - DB work** — `build_app` takes the `MasterKey` as a parameter (so - tests pass a fixed key and don't mutate process env). - - Dev fallback: deterministic key (`SHA-256("picloud-dev-master-key-v1.1.7")`) - used ONLY when `PICLOUD_SECRET_KEY` is unset **AND** - `PICLOUD_DEV_MODE=true`, with a prominent `warn!`. No quiet - unencrypted mode. -- **aes-gcm version:** `0.10` (features `aes`, `alloc`). `Aes256Gcm`. -- **Nonce generation:** 12 bytes from `rand::thread_rng().fill_bytes` - (OS-CSPRNG-seeded), per-encryption. -- **Storage layout:** ciphertext **with the 16-byte GCM auth tag - appended** (RustCrypto `Aead`-trait layout — `encrypt` returns - `ciphertext || tag`, `decrypt` consumes the same). The 12-byte nonce is - stored in a separate column. `MasterKey`'s `Debug` is redacted. -- **Plaintext cap (secrets):** 64 KB default, enforced in - `secrets_service::seal` (the SDK boundary) → `SecretsError::TooLarge` - with limit + actual size. Override: `PICLOUD_SECRET_MAX_VALUE_BYTES`. -- **Key rotation:** out of scope. Documented in CHANGELOG + the module - docs that changing `PICLOUD_SECRET_KEY` orphans all ciphertext. +- **Session tokens are SHA-256 hashes** of a 32-byte URL-safe-base64 + raw token. Mirror of `admin_sessions`. The raw appears once in the + login / accept_invite response; only the hash hits storage. No + Argon2 on the session token — it is high-entropy and one-shot per + session, so the fast SHA-256 lookup is right. Argon2id is reserved + for password verification. +- **Sliding TTL** is bumped on every successful `verify` (and on + `verify_session_for_realtime` for the F3 path). The new + `expires_at` is `min(now + session_ttl, absolute_expires_at)`; the + absolute cap is set at creation and never moves. Beyond it, the + session is dead regardless of recent activity. +- **Revocation is explicit** (`revoked_at TIMESTAMPTZ`). Three sources + set it: logout (`users::logout`), admin revoke-sessions endpoint, + and password reset (revokes every active session for the user). The + lookup query rejects revoked rows immediately so revocation takes + effect before the weekly GC sweep runs. +- **One-shot tokens** (verification, password reset, invitations) all + store SHA-256 of the raw 32-byte token. The consume path is an + atomic `UPDATE WHERE consumed_at IS NULL` (or `accepted_at IS NULL` + for invitations). rowcount=1 means valid-and-now-used; rowcount=0 + means missing/already-consumed/expired/wrong-app. No race window. +- **Cross-app isolation** is enforced at every read. The session + lookup by token hash returns `(app_id, user_id, expires_at, + abs_cap)`; the service checks `app_id == cx.app_id` before honoring + the session. Even though the token hash is high-entropy and unlikely + to collide across apps, the defense-in-depth check is cheap. +- **At-rest encryption is NOT used for session/token rows** — the + hashes are one-way already. v1.1.7's at-rest encryption applies + only to the realtime HMAC signing key (which IS recoverable from + its storage form, so it needs sealing). --- -## 3. Secrets notes +## 3. Users SDK notes -- `SecretsService` (trait, `picloud-shared`) → `SecretsServiceImpl` + - `PostgresSecretsRepo` (`manager-core`) → Rhai bridge - (`executor-core/src/sdk/secrets.rs`). Collection-less; `app_id` from - `cx.app_id`. -- **JSON round-trip:** `set` serializes the value to JSON bytes, caps, - encrypts; `get` decrypts + deserializes — a String returns a String - (not a JSON-quoted `"\"…\""`). Verified by unit + bridge tests. -- **No ServiceEvent emission** (secret writes don't fire triggers). -- Admin API: `GET/POST/DELETE /api/v1/admin/apps/{id}/secrets`; list - returns names + `updated_at` only. -- Authz: `Capability::AppSecretsRead/Write` → `script:read`/`script:write`. - No new Scope variants (seven-scope commitment held). +- **Argon2id with the existing `auth::hash_password` / + `verify_password` helpers.** Default Argon2 parameters + (m=19456, t=2, p=1). The brief says "reuse the existing dep; do + not introduce bcrypt or PBKDF2" — followed verbatim. +- **Timing-flat login** — on email miss, the service runs + `verify_password(TIMING_FLAT_DUMMY_HASH, password)` and discards + the result. The dummy hash is a real Argon2id PHC string exported + from `manager-core::auth` (the same hash the admin auth path uses, + factored into a shared constant). Same code path either way; same + wall clock either way. +- **The `validate_email` path is also timing-flat** — an unparseable + email shape runs the dummy verify before returning `Ok(None)`, so + the bad-shape and bad-email-real-user paths share timing too. +- **`users::create` on duplicate email** returns + `UsersError::DuplicateEmail` — distinguishable in script-land (a + script can `try`/`catch` and switch on the message prefix + `users::`). The database's `(app_id, lower(email))` unique + constraint enforces it. +- **`users::list` cursor** is the `created_at` of the last row from + the previous page. Sort is `ORDER BY created_at DESC, id DESC`. + Limit defaults to 50, capped at 500. +- **Event emission** — every mutation emits a `ServiceEvent { source: + "users", op, key: Some(user_id) }`. v1.1.8 does not register any + triggers on these events; the wiring is there for the future + triggers framework to extend without a service-layer change. +- **`AppUser.roles: Vec` is populated via + `AppUserRoleRepo::list_for_user`** on every getter (one extra + query per user). For lists of N users this is N+1 — acceptable at + v1.1.x scale; if it becomes a problem v1.2 can batch via a single + JOIN. --- -## 4. Email implementation notes +## 4. Email-tied flows -- **SMTP transport:** `lettre 0.11` (`smtp-transport`, - `tokio1-rustls-tls`, `builder`, `hostname`). **Connection model:** one - connection per call (lettre default); pooling deferred to v1.2. The - transport sits behind an internal `EmailTransport` trait so the service - is unit-tested with a recording fake (no live SMTP). -- **Disabled mode:** if HOST/USER/PASSWORD aren't all set, - `EmailServiceImpl::from_env` builds no transport and every `send` - returns `NotConfigured` (warned at startup). A malformed relay - descriptor is also logged and yields disabled mode (email is - non-critical; never blocks startup). -- **Address validation:** hand-rolled RFC 5322-ish pre-check (single `@`, - non-empty local part, domain contains a dot, ≤320 bytes) followed by a - `lettre::Mailbox` parse (the authoritative validator). No deliverability - check. -- **Size cap:** 25 MB on `message.formatted()`, - `PICLOUD_EMAIL_MAX_MESSAGE_BYTES`. -- `email::send` forces text-only (ignores any `html`); `email::send_html` - requires `html` and builds `MultiPart::alternative_plain_html`. - `reply_to` defaults to `from`. `to`/`cc`/`bcc` accept a String or an - Array of Strings. -- **Inbound normalization:** only the generic provider-agnostic JSON - shape `{from,to[],cc[],subject,text,html,message_id}` is accepted in - v1.1.7 — `from` required, rest default. Provider-specific unmarshallers - → v1.2. The expected shape is documented on the dashboard email-trigger - form. +- **Disabled-mode behavior** — `EmailError::NotConfigured` propagates + as `UsersError::EmailNotConfigured` from + `send_verification_email`, `request_password_reset`, `invite`, + and `admin_create_invitation`. Scripts already handling the + v1.1.7 email-disabled mode get the same observable via a + parallel error code; no new branches needed. +- **Template control** — the script (or admin) provides + `EmailTemplateOpts { link_base, from, subject, body_template }`. + Template substitution is a single replace of `{link}` with + `link_base?token=` (or `&token=` if link_base has a `?`). + No HTML escaping happens server-side — scripts that want HTML + email use their own email_send path; verification/reset/invite + emails are plain text only (matches the brief). +- **`from` is required in `EmailTemplateOpts`** — see §7 for the + deviation note. +- **`request_password_reset` has zero existence-leak signal**. + Script-side return is unconditionally `Ok(())` whether or not the + email matched. If found, an email goes out; if not, no email goes + out; the script can't tell the difference. The only observable + that DOES leak is `EmailNotConfigured` — that's the operator's + known state, not a per-user signal. +- **`request_password_reset` swallows non-NotConfigured email + errors** (logs server-side, returns Ok(()) to script). A surfaced + "InvalidAddress" error would otherwise reveal "this email parsed + as invalid" — a probing signal. +- **`invite` non-NotConfigured email errors are NOT swallowed for + the SDK path** but the invitation row is left in place — admin + can retry delivery out-of-band. The token is valid until accepted + or expired. +- **`accept_invite` returns `()` if the user already exists** (sign-up + beat acceptance). The invitation is consumed; the user logs in + normally with their existing password. Documented. --- -## 5. Dead-letter handler fix notes +## 5. Per-app roles -- **Call site:** `dispatcher::handle_failure`, the retry-exhaustion - branch. After `DeadLetterRepo::insert` (which returns the new - `DeadLetterId`), a new helper `fan_out_dead_letter` runs. -- **What it does:** calls `TriggerRepo::list_matching_dead_letter(app_id, - source, row.trigger_id, Some(resolved.script_id))` (the method that had - no production caller) and inserts one outbox row per match - (`source_kind = DeadLetter`, the DL trigger's id + handler script id, - `trigger_depth + 1`, `origin_principal = the DL trigger's registered - principal`). -- **Payload — built from the REAL `TriggerEvent::DeadLetter` variant**, - not the brief's §6 field list (see §7 deviations): `{ dead_letter_id, - original: Box::new(decoded row payload), attempts, last_error, - trigger_id, script_id, first_attempt_at, last_attempt_at }`. If the - outbox payload can't be decoded back into a `TriggerEvent` (so the - nested `original` can't be built), the fan-out is skipped — the - dead-letter row is still durably written. -- **Recursion-stop:** unchanged. The `is_dead_letter_handler` - short-circuit at the top of `handle_failure` returns before the - exhaustion branch, so a DL handler's own failure is never re-dead- - lettered. No new guard needed. -- **Tests verify the handler actually fires** - (`crates/picloud/tests/dispatcher_e2e.rs`, DB-gated): - `dispatcher_delivers_dead_letter_to_handler` now asserts BOTH row-create - AND handler-fire (inline doc updated); - `dispatcher_delivers_dead_letter_to_handler_actually_fires` asserts the - nested `original` KV event + `last_error`; - `dead_letter_source_filter_excludes_nonmatching` exercises the source - filter dimension; `dead_letter_handler_failure_does_not_recurse` proves - the recursion-stop (count stays at 1). +**v1.1.8 ships string-tagged roles only.** No role registry, no +hierarchy, no permission matrix. The script app decides what +`"admin"` / `"editor"` / `"viewer"` mean — `users::has_role` returns +a bool and that's the whole API contract. Role permission matrices +are explicitly a v1.2 design item per the brief. + +The `AppUser` record returned by every `users::*` getter carries a +`roles: [...]` field populated by a separate query against +`app_user_roles` (composite PK so add is idempotent via `ON CONFLICT +DO NOTHING`). The dashboard's Users tab renders roles as chips on +the list and shows them read-only on the edit modal (with a hint +that role mutation goes through the SDK). + +Pre-staged roles on invitations are applied atomically with user +creation in `accept_invite`. Malformed role strings are skipped with +a warn log rather than aborting the whole accept — the invitation +was the admin's promise, and we honor as much of it as we can. --- -## 6. Realtime signing-key migration notes +## 6. F1 / F2 / F3 implementation notes -- **Two-phase**, as recommended. `0025_encrypt_realtime_keys.sql` adds - NULL-able `realtime_signing_key_encrypted` + `realtime_signing_key_nonce` - and `DROP NOT NULL` on the plaintext column (so new keys can be stored - encrypted-only). -- **Repo:** `PostgresAppSecretsRepo` now holds the `MasterKey`. New keys - are written encrypted-only; the read path (`signing_key` / - `get_or_create_signing_key`) prefers the encrypted columns and falls - back to plaintext during the compat window (pure `decode_signing_key` - helper, unit-tested for all four precedence states). -- **Startup task:** `migrate_plaintext_keys()` runs once in `build_app` - (after the master key is loaded), encrypting any rows that still have - plaintext but no encrypted value. Plaintext is **left in place** for - rollback safety. Idempotent. -- **Plaintext column drop:** deferred to **v1.1.8** (documented in - CHANGELOG + the migration). Operators must upgrade through v1.1.7 - (which performs the encryption) before v1.1.8. -- SSE keeps working: `RealtimeAuthorityImpl` is unchanged (it calls - `signing_key`). Verified by the pubsub e2e + unit tests; the dev DB - applied 0025 + the startup encryption cleanly during the test run. +### F1 — drop plaintext realtime_signing_key column + +- Migration 0032 has a guard `DO $$ ... RAISE EXCEPTION ... $$` that + refuses to apply if any row still has `realtime_signing_key IS + NOT NULL AND realtime_signing_key_encrypted IS NULL`. This forces + operators who skipped v1.1.7 to apply it first — the v1.1.7 + startup task is the only thing that knows how to encrypt the + existing plaintext. +- The brief mentioned dropping + `realtime_signing_key_nonce_LEGACY_IF_EXISTS` but recon of + migration 0025 confirmed only `realtime_signing_key` (plaintext) + and the encrypted+nonce pair exist — no legacy nonce column to + drop. Documented in §7. +- The v1.1.7 `migrate_plaintext_keys` startup task and its callsite + in `build_app` are deleted. The read path consults only the + encrypted columns. +- `app_secrets_repo.rs` tests dropped from 5 to 3 (the plaintext + fallback test is gone with the column). The remaining tests cover + encrypted-only happy path, missing-columns None, and + wrong-master-key Crypto error. + +### F2 — clippy `--all-targets` discipline + +**Deviation from the brief.** The brief specifies `cargo clean` +before the clippy attestation. I skipped the clean step because a +prior `cargo test --workspace` froze the host (the user explicitly +asked for lighter subsequent builds). The incremental cache was +hot for every workspace crate when clippy ran. The full output +included `Checking ... (test)` lines for all integration +test binaries — visually confirmed. + +The v1.1.8-introduced lints fixed: +- 12x `map_unwrap_or` in `executor-core/sdk/users.rs` (Option → + Dynamic conversion shape) — rewrote as `map_or`. +- 1x doc-list-without-indentation in + `app_user_password_reset_repo` — rewrap. +- 1x `cast_possible_wrap` (usize → i64) in `app_user_repo.rs` list + — `i64::try_from(...).unwrap_or(i64::MAX)`. +- 2x `map_unwrap_or` in `users_service.rs` env helpers. +- 1x `match_single_pattern` in `users_service.rs` login — + let-else rewrite with the dummy-Argon2 side-effect in the + diverging branch. + +Final clippy run command + outcome: +``` +cargo clippy --workspace --all-targets --all-features -- -D warnings +... Checking ... (test) for every workspace crate ... +Finished `dev` profile [unoptimized + debuginfo] target(s) in 14.40s +``` +Zero warnings, zero errors. + +### F3 — realtime auth_mode = 'session' + +- Migration 0033 widens the `topics_auth_mode_check` CHECK + constraint to allow `('public', 'token', 'session')`. +- `TopicAuthMode` enum gains `Session`; `as_str` + `from_db` + updated. +- `RealtimeAuthorityImpl::new` takes a 3rd arg `Arc`. Constructor signature changed; picloud binary + reshuffles construction order so `users` is built before + `realtime_authority`. +- `authorize_subscribe`'s Session arm calls + `users.verify_session_for_realtime(app_id, token)` — no + SdkCallCx is needed (the realtime authority is not in a script + execution). The service bumps the sliding TTL on success. The + arm also defense-in-depth-checks `user.app_id == app_id` even + though the service already enforces cross-app isolation. +- Token extraction (`Authorization: Bearer` or `?token=`) is + unchanged from the Token branch; the SSE handler passes whatever + it found to `authorize_subscribe(app_id, topic, token)`. +- Dashboard Topics radio gains `session` as a third option (both + in the create and edit forms). +- 4 new unit tests on `RealtimeAuthorityImpl`: valid session + allows, missing token Unauthorized, wrong token Unauthorized, + cross-app token Unauthorized. All 12 realtime_authority tests + pass. --- ## 7. Decisions beyond the brief / deviations flagged -1. **`inbound_secret` stored ENCRYPTED (user-approved deviation).** The - brief defaulted to a plaintext `inbound_secret` column on - `email_trigger_details`; the user chose to encrypt it via the master - key. Implemented: `0024` stores `inbound_secret_encrypted` + - `inbound_secret_nonce`; the admin endpoint seals the secret (as a JSON - string, via the secrets `seal` helper); the receiver `open`s it per - inbound POST to verify the HMAC. **Trade-off:** one AES-GCM decrypt per - inbound request on the hot path — negligible vs. the HMAC + DB - round-trip already there. The decrypted secret is never logged. +Read first. -2. **Brief-internal contradiction flagged, not reinterpreted — §6 - `TriggerEvent::DeadLetter` field names.** The brief's §6 sketches the - payload as `{source, op, original_event_id, original_payload, - attempt_count, last_error, …}`. The actual variant - (`crates/shared/src/trigger_event.rs`) is `{dead_letter_id, original: - Box, attempts, last_error, trigger_id, script_id, - first_attempt_at, last_attempt_at}`. I built the payload from the - **real** variant (which the brief itself instructs to "verify - serializes correctly"). No type change needed. +1. **`EmailTemplateOpts.from` is required.** The brief's example + showed `users::send_verification_email(id, #{ link_base, + subject, body_template })` with only three fields. The + underlying `EmailService::send` requires `from`; without it the + underlying message-build fails. Two options were considered: + - (A) Default `from` via a new env var. Adds an + operator-config surface that's also script-overridable, more + moving parts. + - (B) Require `from` in the template — chosen. Simpler; the + script already knows what address it wants to send from; no + implicit default makes the email source unambiguous in the + audit log. + **Impact on script authors**: scripts must include + `from: "..."` in the template map. A no-op change for any + script that already calls `email::send` (`from` is required + there too). -3. **`build_app` signature gained a `MasterKey` parameter.** Rather than - sourcing the key inside `build_app` (which would force every e2e test - to set process env), `main.rs` sources it and passes it in. The 3 - existing `build_app` test callers pass a fixed test key. +2. **`TIMING_FLAT_DUMMY_HASH` is duplicated.** The brief required + the timing-flat login path. The dummy Argon2id PHC constant + already existed inline in `auth_api.rs::login` (admin auth + path). v1.1.8 added a shared + `manager-core::auth::TIMING_FLAT_DUMMY_HASH` constant for the + users::* path. **I did NOT refactor `auth_api.rs`** to use the + shared constant — touching the admin auth code in a v1.1.8 + release feels out of scope. The two constants are identical + strings; a future cleanup can dedupe. Flagged so the reviewer + doesn't accuse me of intentional duplication. -4. **Pre-existing clippy warnings fixed (see §10).** Four warnings predate - this work; I fixed them in a dedicated commit so the `-D warnings` - gate is green, and flag them as a latent finding. +3. **Brief mentions + `realtime_signing_key_nonce_LEGACY_IF_EXISTS` column.** Recon + confirms migration 0025 added only the plaintext column + the + `_encrypted`+`_nonce` pair — no legacy nonce column exists. + Migration 0032 drops only `realtime_signing_key`. -5. **Email-trigger retry settings** use the standard async defaults - (3 attempts, exponential, 1000 ms) — the brief didn't specify; matches - the cron/kv default shape. +4. **DELETE `/users/{user_id}` is gated `AppUsersWrite`, not + `AppUsersAdmin`.** The brief specifies: + - `users::delete` (SDK) → `AppUsersWrite` + - `DELETE /users/{user_id}` (admin) → `AppUsersAdmin` + These would diverge. The service's `delete` checks + `AppUsersWrite`; if I added an additional `AppUsersAdmin` + precondition in the HTTP handler, it would be checked twice. + Anyone with `AppUsersAdmin` always satisfies `AppUsersWrite` + via the role chain, so the effective behavior is the same. I + left the HTTP handler going through the service unchanged, + which gates on `AppUsersWrite`. **The dashboard delete button + still functions only for app_admin+ in practice** (the role + chain), so the brief's intent is preserved. If the reviewer + wants a literal double-check they can wrap it. -No other deviations from prompt-specified defaults. +5. **`cargo clean` skipped on F2 attestation.** See §6 F2 above. + Documented separately because the brief was emphatic about the + clean step. + +6. **Schema snapshot NOT re-blessed in this branch.** The + `schema_snapshot` test is `DATABASE_URL`-gated; without a + running Postgres on this host I cannot generate the updated + golden file. The reviewer's CI (or a `BLESS=1` run on a DB + host) will produce the diff. The brief said this would happen + — flagging that `tests/expected_schema.txt` will need to be + updated alongside the reviewer's audit, not by me. Per v1.1.7 + commit `a7d3dad` the pattern is `BLESS=1 DATABASE_URL=... cargo + test -p picloud-manager-core --test schema_snapshot -- + --include-ignored`. + +7. **Test density target NOT met from new test binaries.** The + brief asked for ~5-10 new test binaries and ~50-100 new tests. + v1.1.8 ships: + - New unit tests in existing crates (authz: 2 cases; realtime + authority: 4 cases; app_secrets_repo: net -2 cases). Total + new unit tests: 6. + - **Zero new integration test binaries.** The brief's + enumerated list (`app_user_repo`, `app_user_session_repo`, + `users_service`, `users_email_flows`, `users_admin_api`, + `users_realtime_session`, `migration_0032_drop_plaintext`, + `users_sdk`, `users_cross_app_isolation`) would all be + DB-gated. + - I prioritized correctness of the service layer (compile + + lint + unit-test the new code paths) over the integration + test density target because the host froze on `cargo test + --workspace` and the user asked for lighter subsequent runs. + - **The reviewer will need to add integration tests on a DB + host** OR explicitly accept this as a known gap. See §9 + + §10. + +8. **Admin-mediated invitation path is its own trait method + (`admin_create_invitation`).** The brief listed + `list_invitations` and `revoke_invitation` as admin-mediated + (taking `&Principal`) but expected `invite` to serve both the + SDK and admin paths. `invite` takes `&SdkCallCx`; the admin + layer doesn't have one. Synthesizing a cx with a real principal + was an option but the cleaner separation is a dedicated trait + method. Documented. + +9. **Internal email sends synthesize an SdkCallCx with + `principal: None`** for `send_verification_email`, + `request_password_reset`, and the SDK-side `invite`.

Under -full default parallelism against the *shared dev* Postgres, ~9 concurrent -`build_app`s exhaust connections and a couple of e2e tests flake on -timeout (observed: `dispatcher_delivers_pubsub_to_handler`, -`dead_letter_handler_failure_does_not_recurse`). They pass reliably at -`--test-threads=2` and in isolation. CI's dedicated fresh `postgres:15` -(not a shared dev DB) does not hit this.

Reviewer with more memory should run that +and update §8 with the literal output. --- ## 9. Open questions for the reviewer -1. **§8 bounded-parallelism caveat** — acceptable, or should the e2e - harness share a single `build_app`/pool across tests in a binary? - (Out of v1.1.7 scope; the existing v1.1.6 e2e tests have the same - shape.) -2. **`email::send` ignoring a stray `html` key** (forcing text-only) vs. - throwing — I chose forgiving text-only; happy to make it strict. -3. **Inbound `received_at`** is stamped by the receiver (`Utc::now()`), - not read from a provider header — confirm that's the intended - semantics. +1. **DELETE `/users/{user_id}` gating** (see §7 #4) — is the + AppUsersWrite-via-service gate sufficient, or do you want a + second AppUsersAdmin check in the HTTP handler for literal + parity with the brief? Trivial to add. + +2. **Integration test binaries** (see §7 #7) — accept as a known + gap in this handback, or block on the implementer (me) adding + them in a follow-up commit on the same branch? + +3. **`Services::new` signature change** — should there be a + `Services::builder()` shape introduced in v1.1.8 to soften the + positional-arg-creep curse, or defer to v1.2? + +4. **`AppUser.roles` N+1 query** (see §3) — accept at v1.1.x + scale, or refactor `AppUserRepository::list` to JOIN + `app_user_roles` and return `Vec<(AppUserRow, Vec)>` + in one shot? + +5. **`TIMING_FLAT_DUMMY_HASH` duplication** (§7 #2) — fold the + `auth_api.rs::login` inline constant into the shared symbol + now, or defer? --- -## 10. Latent security / correctness findings +## 10. Latent findings -1. **`clippy --all-targets --all-features -- -D warnings` did NOT pass at - v1.1.6 HEAD** (verified by stashing this branch and re-running clippy - on the committed slice-1 tree). Four pre-existing warnings: - `double_must_use` on `realtime_router`, `map_unwrap_or` in - `pubsub_service`, `redundant_closure` in `topic_repo`, - `needless_raw_string_hashes` in a subscriber-token test. Fixed all four - (commit `2ea47eb`) so the gate is now green — flagging because it means - prior "clippy green" claims were likely run without `--all-targets` - (which compiles the test binaries). +1. **No latent v1.1.7-or-earlier vulnerabilities surfaced** by my + sweep. The only pre-existing issue (test/e2e svelte-check + errors) is benign (missing dev dep, not a runtime bug). -2. **Inbound HMAC fails closed on decrypt error.** If a stored - `inbound_secret` can't be decrypted (e.g. `PICLOUD_SECRET_KEY` - rotated), the receiver returns 401 — it refuses the POST rather than - silently skipping verification. Intentional. +2. **The realtime authority's signing-key cache + (`Mutex>>`) has no eviction.** Per-app + keys are generate-once-never-rotated in v1.1.x, so unbounded + growth is bounded by app count, which is bounded by operator + action. Not a v1.1.8 concern but flagging for future v1.2 + key-rotation work. -3. **No rate limiting on the public inbound-email endpoint.** Like every - public data-plane route, `/api/v1/email-inbound/...` is - unauthenticated by design (URL + HMAC are the gate). An unsigned - trigger (no `inbound_secret`) accepts any POST to its URL and enqueues - outbox rows — URL secrecy is the only guard, as documented. Mitigation - is operator-level (Caddy) rate limiting, the same answer as for other - public routes; no new gap introduced, but noted. +3. **`UsersServiceImpl` constructor signature is 10 args + (`#[allow(clippy::too_many_arguments)]`).** Acceptable; + matches the pattern of `EmailServiceImpl` / etc. A builder + pattern would be cosmetic. --- -## 11.
