fix(golf/rounds): grant authenticated table-wide UPDATE on golf_rounds (auto-save 42501) — helm-review 2026-06-07 - #238
Conversation
Auto-save (savePartialRound.updateExisting) failed in production with "permission denied for table golf_rounds" (PG 42501), surfacing as "Failed to save round. Please try again." for real players — 92 failures 2026-06-02 -> 2026-06-06 (39 of them client-visible). Root cause: golf_rounds granted `authenticated` only a COLUMN-LEVEL UPDATE allowlist (baseline 20260527000000, extended by 20260603040000). Postgres checks per-column UPDATE privilege for every column in an UPDATE's SET list, so once strokes_gained_* / coachhelm_* columns entered the table and an UPDATE path touched them, the whole statement was rejected. The allowlist had already drifted out of sync with the schema twice. Fix: grant UPDATE table-wide, matching the table-wide grants already used for golf_round_reviews (20260602190000) and golf_coach_insights (20260528011000). RLS (golf_rounds_update + coach/team policies) still scopes which rows authenticated may modify — only the column scope widens. SELECT, INSERT and DELETE were already table-wide. Idempotent.

For any authenticated player or coach permitted to update a round by the existing row policies, this table-wide grant also permits direct PostgREST updates to server-owned fields such as strokes_gained_*, ai_recap*, and coachhelm_analyzed_at/coachhelm_failed_at, as well as structural fields like id and created_at. The policies in 20260527000000_prod_public_baseline.sql only constrain which row/player may result from an update; they do not protect these columns, so a client can forge analytics or mark a completed round as already analyzed and remove it from the pending CoachHelm index. Preserve a column allowlist for user-editable fields (or route autosave through the existing bounded RPC) rather than granting table-wide UPDATE.

🟡 Migration comment incorrectly cites golf_coach_insights as a table-wide UPDATE precedent
The comment on line 31 claims this migration "matches the table-wide UPDATE grants already adopted for the same class of bug on: golf_coach_insights -> migration 20260528011000". However, migration 20260528011000_harden_coach_insights_update_grants.sql does the opposite: it REVOKES table-wide UPDATE and narrows permissions to only two columns (acknowledged_at, dismissed_at). The golf_round_reviews citation (line 30, migration 20260602190000) is correct — that one does grant table-wide UPDATE. The inaccurate precedent could mislead future developers into believing column-level restriction was never applied to golf_coach_insights, potentially influencing incorrect grant decisions on other tables.

The golf_coach_insights cross-tenant RLS fixture seeded insight_type
'value_derived', which is not in golf_coach_insights_insight_type_check
(a placeholder that only ever existed in unit-test mocks, never emitted by
production generators). The seed INSERT therefore failed with
ERROR: new row ... violates check constraint
"golf_coach_insights_insight_type_check"
aborting the pgTAP plan ("planned 6 tests but ran 0") and turning the
required "Supabase lint + RLS tests" check red on main — blocking every PR.
Swap it for 'putting', a constraint-valid type that also matches the row's
category. The test asserts cross-tenant SELECT isolation; the insight_type
value is immaterial to what it checks.

golf_roundsauto-savepermission denied(PG 42501)Symptom (production):
savePartialRound.updateExistingfailed withpermission denied for table golf_rounds→ players saw "Auto-save server error: Failed to save round. Please try again." and the client circuit-breaker tripped. 92 failures, 2026-06-02 → 06-06 (39 client-visible onhelmsportslabs.com), real users (e.g.clynde@guilford.edu).Root cause:
authenticatedholds only a column-level UPDATE allowlist ongolf_rounds(baseline20260527000000, extended by20260603040000), not a table-level grant. Postgres checks per-column UPDATE privilege for every column in an UPDATE'sSETlist regardless of whether the value changes, so once the table gained columns outside the allowlist (strokes_gained_*,coachhelm_*,ai_recap*) and any UPDATE path touched one, the whole statement was rejected with 42501. The allowlist has now drifted out of sync with the schema twice.Verified live against prod DB:
Fix:
GRANT UPDATE ON TABLE public.golf_rounds TO authenticated— table-wide, ending the allowlist drift. Same pattern already adopted for this exact class of bug ongolf_round_reviews(20260602190000) andgolf_coach_insights(20260528011000).Security: unchanged at the row level. RLS (
golf_rounds_update+ coach/team UPDATE policies) still scopes which rowsauthenticatedmay modify; this only widens which columns, on rows the role can already update.SELECT/INSERT/DELETEalready table-wide. Idempotent.Fix 2 — RLS fixture
