feat(server): rate-limit ledger, offline user merge, keyset pagination, JWT-only admin gates - #62
Merged
Conversation
…n, JWT-only admin gates - Add rate_limit_attempts ledger + generic tryConsumeRateLimit (per-user ai-gen/ai-homepage keys, window-aware pruning) replacing the fake ai_recommendations cooldown row; failed AI calls release their slot - Move legacy duplicate-account reconciliation to a daily user-maintenance task (helpers/user-merge) with deterministic canonical matching - Replace offset pagination with keyset pagination for episode feeds - Gate admin access solely on the signed JWT claim; accept publicMetadata, public_meta, and legacy Convex-era metadata claim shapes - Race-safe upserts for updateProgress/markShowEpisodesAndStatus; SQL- aggregated list previews; lists/homepage status CHECK constraints - Add vitest suite (32 tests), migration 0008, docs and plan updates

📝 WalkthroughWalkthroughThe pull request adds atomic rate limiting, database constraints, claim-based admin authorization, offline duplicate-user maintenance, race-safe watch-item updates, keyset pagination, scheduled tasks, Vitest coverage, and related documentation. ChangesBackend correctness and maintenance
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔴 Critical · up to This PR changes account consolidation, authorization, rate limiting, and database migration behavior, but the migration can delete existing list items and user merging can hide duplicate-owned lists; stale JWT claims may also preserve revoked admin access. These are release-blocking correctness, data-loss, and security risks that should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@docs/architecture-decisions.md`:
- Around line 103-107: Update the ADR-004 consequences section to remove the
statement that an absent admin claim triggers a Clerk API call, and state that
authorization remains based exclusively on the verified signed JWT claim.
Qualify demotion timing by referencing the applicable token refresh or
revocation policy.
In `@drizzle/0008_wide_shocker.sql`:
- Around line 8-47: Update the migration around the __new_lists replacement to
preserve list_items: detach or rebuild list_items before DROP TABLE lists,
retain and restore its schema, indexes, list_id foreign key with cascade
behavior, and all existing data, then complete the lists replacement without
cascading deletion.
- Around line 18-21: The migration’s INSERT statements must normalize legacy
enum values before inserting into the constrained replacement tables: for lists,
convert invalid visibility and list_type values to their appropriate valid
fallback values, and for homepage_recommendations, map any status outside none,
success, or failed to none. Update the INSERT SELECT expressions associated with
the new table definitions while preserving valid existing values and all other
columns.
In `@plans/backend-fix-plan.md`:
- Around line 131-133: Add backup and validation steps to the migration
procedure before running `pnpm db:migrate:local` and `pnpm db:migrate:prod`:
record row counts for `lists`, `list_items`, and `homepage_recommendations`,
export a database backup, then rerun the same counts after migration and compare
them to detect cascade deletions while retaining the backup for recovery.
In `@src/server/db/schema.ts`:
- Around line 283-291: Update the daily user-maintenance task to perform a
bounded delete of rateLimitAttempts rows older than the longest supported
rate-limit window, independently of individual keys; reuse the existing schema
and database access symbols, and keep per-key cleanup in tryConsumeRateLimit
unchanged.
- Around line 120-124: Update the CHECK constraints in the schema definitions,
including lists_visibility_ck and lists_list_type_ck, to derive their
allowed-value SQL expressions from the canonical LIST_VISIBILITIES, LIST_TYPES,
and HOMEPAGE_REC_STATUSES constants. Generate inline SQL string literals rather
than bound parameters so the resulting SQLite CHECK definitions remain valid,
while preserving the existing constraint names and semantics.
In `@src/server/fns/watchlist.ts`:
- Around line 533-545: The watchlist upsert currently increments watchlistRev
twice when data.progressStatus is defined. Update upsertWatchItem or this
updateProgress flow so this operation relies on exactly one bump, suppressing
the helper bump or removing the unconditional secondary path while preserving
the existing race-safe upsert behavior.
In `@src/server/helpers/rate-limit.ts`:
- Around line 40-75: The rate-limit slot claim in the shown flow is not atomic,
allowing concurrent calls to both reject themselves. Update the rate-limit
helper around the rateLimitAttempts insert and blocking query to serialize the
check-and-insert or use an atomic conditional insert, ensuring exactly one
concurrent fresh request returns allowed: true; add a concurrent-call test
covering this behavior.
In `@src/server/helpers/user-merge.ts`:
- Around line 96-100: Update mergeDuplicateUsers to migrate duplicate-owned
lists and listItems to the canonical user before consolidation completes.
Reparent or merge both tables, explicitly resolving conflicts on
lists_user_name_uq and list_items_list_media_uq so existing canonical records
are preserved without uniqueness failures.
In `@src/server/rbac.ts`:
- Around line 167-173: Update the admin authorization paths using
isAdminByClaims in src/server/rbac.ts lines 167-173 and 206-207, and
src/server/fns/rpc.ts lines 119-123, so revoked admin status cannot remain
effective for the full JWT lifetime. Add an explicit current-state/revocation
check or enforce and document a maximum token lifetime consistently across all
three sites.
In `@src/server/services/picks-list.ts`:
- Around line 34-50: Reserve the “Pebbly Picks” name for the system list: reject
it in createCustomListArgsSchema and updateCustomListArgsSchema, handle any
existing custom-name collisions in the relevant flows, and update
appendToPicksList’s pebblyList lookup to require listType “pebbly-picks” in
addition to the existing user and name predicates.

Normalize legacy enum values before copying rows.
The migration copies existing lists.visibility, lists.list_type, and homepage_recommendations.status values into tables with new CHECK constraints. If any existing value is outside its enum, the copy fails and aborts the migration. Normalize invalid list values during the copy and map invalid status values to 'none'.

- Expand TMDB image URLs into width-ladder srcsets so phones download w185/w342 variants instead of fixed w500/w780 JPEGs (unpic has no TMDB provider); attached only when sizes is declared. - Move SignInButton/UserButton/@clerk/ui theme out of the entry chunk behind a lazy AccountButton used by both navs.
- Replace Gemini REST with @openrouter/sdk streaming (reasoning-token telemetry); openrouter/free currently routes to slow reasoning models. - Raise the stream timeout 30s -> 90s: measured SDK streams exceed 30s, which surfaced to users as a generic api_unavailable. - Propagate the provider error message out of generateRecommendationResponse so failures log/return the real cause instead of an empty fallback.
…cks/merge guards - ai: migrate recommendation generation to @openrouter/sdk (callOpenRouterAI with streaming + reasoningTokens), add OPENROUTER_API_KEY env with legacy GEMINI_API_KEY fallback and unified validation warning - rate-limit: replace racy insert-then-check with atomic INSERT..SELECT WHERE NOT EXISTS, add MAX_RATE_LIMIT_WINDOW_MS, global pruneStaleRateLimitRows via daily user-maintenance task, self-healing ensureRateLimitTable for missing migrations, and node:sqlite ledger test suite (concurrent/one-window/prune) - lists: reserve "Pebbly Picks" (case-insensitive) for system list, block creation/rename to reserved name, make picks-list lookup require listType pebbly-picks and tolerate legacy squatters, use enumLiterals for CHECK constraints in schema.ts - user-merge: reparent lists + listItems onto canonical user with name-collision handling, batched by MAX_IDS_PER_IN_CLAUSE - watchlist: add skipRevBump to upsertWatchItem so markShowEpisodesAndStatus bumps watchlistRev exactly once - request-logger: opt-in RPC payload tracing via LOG_RPC_PAYLOADS (non-prod only, checks globalThis.__env__/process.env/import.meta.env), seroval decode for framed streams, large-payload summarization, cleaner serverFn ids - infra: drizzle 0008 stash/rebuild list_items safely, add seroval + openrouter deps, vitest --experimental-sqlite for node:sqlite, deployment backup/verify notes and architecture decisions
