feat(resume): real persistence on the shared Supabase DB

[ltanafranca1004]

What

Moves the AI resume builder off the localStorage prototype onto the shared Supabase DB (wrbauxutkysljmsqojts) so drafts survive across devices/sessions and the daily quota becomes a real DB-backed counter. Savar has signed off on the schema + shared-infra deploy and confirmed no clash. Builds on the inline-editing work (PR #110).

Schema — supabase/migrations/20260825120000_resume_persistence.sql

Committed as the record; applied by hand via the dashboard SQL editor (MCP is read-only, db push unsafe on the drifted shared history).

• resume_drafts — own-row per user (uuid PK, user_id → public.users, jsonb resume + messages, complete, timestamps), four _own RLS policies + explicit grants. Mirrors custom_checklist_tasks + the companion jsonb pattern.
• resume_usage + check_and_increment_resume_usage / refund_resume_message RPCs — SECURITY DEFINER, search_path=public, UTC day rollover, service-role EXECUTE only. Verbatim mirror of the translation_usage quota pair. Limit 60/day.

Data layer — services/resume.ts

CRUD + usage read swap localStorage for Supabase following the Community wiring pattern (isSupabaseConfigured() + getAuthUserId() + row mapper), keeping the localStorage bodies as the !configured local-dev fallback. getResumeUsage reads resume_usage with a UTC date-reset; the client no longer self-increments (the edge fn owns the counter). One-time importLocalDraftsOnce() uploads any pre-existing localStorage drafts to the DB on first authenticated load — only when the user has none server-side, idempotent (upsert by id), flag-gated so it never re-imports. Hook signatures/keys unchanged.

AI turn → the resume-chat edge function (now the production path)

• app/api/resume/route.ts becomes a thin functions.invoke("resume-chat") proxy forwarding the user JWT and preserving upstream 429/503/504 — a near-copy of /api/companion → rag-query.
• resume-chat now enforces the quota (check_and_increment_resume_usage before generate, refund_resume_message on failure), carries the preserveContact guard + the PR feat(resume): inline editing of the live-rendering resume #110 contact prompt line, and is registered in config.toml (verify_jwt on).
• Deleted the retired Node path: lib/resume/{serverRateLimit,generateTurn,prompt}.ts (no remaining importers; schema.ts stays).

⚠️ Gated deploy — do not merge until the deploy is done + verified

The two production writes are held for explicit go-ahead (same gate as every prod deploy): (a) applying the migration via the dashboard SQL editor, and (b) supabase functions deploy resume-chat. Because there's no non-prod DB, the real-DB E2E necessarily runs after (a)+(b). Ordering matters: apply migration + deploy edge fn first, verify, then merge (merging deploys the web code, which then reads the now-existing tables).

Verified so far (pre-deploy)

tsc --noEmit, eslint, npm run check-i18n clean; resume-chat deno check clean. The !isSupabaseConfigured() localStorage fallback is the prior working code, unchanged in behavior.

Post-deploy verification (gated)

Migration + RPCs present (read-only MCP); edge fn ACTIVE + smoke turn; cross-device (build → close tab → reopen loads from the DB row; incognito same-login shows the same drafts); RLS explicitly (user A cannot read/update user B's draft); quota (increments, refunds on failure, 429 at cap); one-time import (imports once, no duplicate on second load).

Walkthrough

The resume flow now uses a same-origin proxy and Supabase resume-chat edge function. Drafts and usage persist in Supabase, with localStorage fallback and one-time draft import. Server-side quota RPCs charge and refund generation requests.

Changes

Resume platform flow

Layer / File(s)	Summary
Draft storage and quota schema supabase/migrations/20260825120000_resume_persistence.sql	Adds resume_drafts, resume_usage, ownership policies, and service-role quota and refund RPCs.
Edge generation and quota handling supabase/functions/resume-chat/index.ts, supabase/config.toml	The edge function enforces a 60-message daily quota, refunds failed generations, preserves contact values, and supports authenticated deployment configuration.
Client draft and usage integration services/resume.ts, hooks/useResume.ts	Draft operations use Supabase when authenticated, retain localStorage fallback, import existing drafts once, read server usage, and pass a derived title string to saveDraftResume.
Same-origin API proxy app/api/resume/route.ts	The route validates and auth-gates requests, invokes resume-chat, and preserves upstream error statuses and JSON bodies.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to b6a3f

The persistence migration can assign locally stored resumes to the wrong signed-in account, potentially exposing contact details and employment history, while failed generations may still consume quota and quota resets can disagree around midnight. These current-head correctness and privacy issues should be fixed before merging.

Thanks @coderabbitai — addressed all four findings in 5f190d8:

1. Import scoping (privacy) — importLocalDraftsOnce is now keyed per-user (unify_resume_imported_v1:<userId>) and gated by an owner claim (unify_resume_owner_v1) + consume-after-import: the first account to load claims the unowned local blob and deletes it after importing, and any other account whose id doesn't match skips it entirely. That closes the "user B imports user A's drafts after A loaded" and "second/other user re-imports" vectors. Residual: the very first authenticated loader on a shared browser still claims genuinely-unowned legacy drafts (they carry no creator id) — an inherent limit of migrating pre-existing unowned data, now shrunk to a single first-load and consumed immediately. Flagging that to the repo owner to confirm they're OK with it vs. dropping the legacy import entirely.
2. Edge-fn refund — refundQuota now inspects the { error } result from refund_resume_message (supabase-js resolves, not rejects, on a PostgREST error) and logs it, instead of silently swallowing.
3. /api/resume error body — forwards the full validated upstream JSON object (preserving code, e.g. daily_limit_reached), keeping the generic fallback for non-JSON bodies.
4. Quota UTC pinning — both RPC day comparisons now use (… at time zone 'UTC')::date, matching the client's UTC getResumeUsage read, so the reset can't disagree at midnight under a stray session timezone.

tsc / eslint clean; the edge fn passes deno check. Migration apply + edge-fn deploy remain gated on the owner's go-ahead.

@ltanafranca1004 Verified in 5f190d8.

• importLocalDraftsOnce now uses a per-user flag and an owner claim. It skips drafts claimed by another user. It removes the legacy draft blob after a successful import.
• refundQuota now checks and logs the resolved PostgREST RPC error.
• /api/resume now forwards the complete upstream JSON error object, including code.
• Both quota RPC date comparisons now use explicit UTC dates.

The residual first-loader limitation for genuinely unowned legacy browser data is documented. The migration apply, Edge Function deployment, and live database verification remain merge prerequisites.

✏️ Learnings added

Learnt from: ltanafranca1004
URL: https://github.com/UnifyCN/web-app/pull/111

Timestamp: 2026-08-25T04:56:01.169Z
Learning: For the AI resume builder migration, `services/resume.ts` treats legacy `unify_resume_drafts_v1` localStorage data as unowned. `importLocalDraftsOnce` uses `unify_resume_owner_v1` plus a per-user `unify_resume_imported_v1:<userId>` flag, and removes the legacy draft blob after a successful import. On a shared browser, the first authenticated user can claim genuinely unowned legacy drafts; this is an inherent limitation unless the legacy import is removed.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.
