…dressed wire names Settle the last blocking RLS design hole (#19 RLS verifier check semantics) and three smaller working-assumption items. Design choice: policy wire names carry an 8-hex SHA-256 suffix over the canonical content tuple (using, withCheck, sort(roles), operation, as). Predicate equivalence collapses to a name match; the verifier never compares bodies for equivalence purposes. One body-level check remains (the per-row tamper check that recomputes the suffix against the introspected body). Three structural wins: - Predicate-equivalence false positives are eliminated by construction. Postgres-side expression-printer normalization (parens, whitespace, cast forms) no longer surfaces as policy_mismatch noise. - Policy rename detection is structurally free (matching hash, different prefix → ALTER POLICY ... RENAME TO). Closes the earlier defer-and-ship-drop+create working assumption. - No version marker needed; the contract storage hash already signals normalizer changes through VERIFY_CODE_HASH_MISMATCH (per ADR 004). Pinned decisions: - A8: TS as field, default permissive (mirrors PSL B2). - C9: content-addressed policy wire names. - C10: RLS verifier semantics built on C9 (rls_policy_renamed, rls_policy_tampered, rls_not_enabled issue kinds). - C11: implicit ENABLE RLS via model-level rls: auto|enabled|disabled. - OC4: content-addressed naming pattern as a future-project backport target for indexes, functions, views, check constraints. Artifacts: - New ADR draft at projects/supabase-integration/specs/ (promotes at close-out with assigned number). - rls.md verifier section rewritten to the content-addressed model. - design-holes.md #19 marked decided; verifier cluster closed.
