+## Committed capture artifact + rot guard
+
+The read-only capture in Step 1 is also committed as a runnable file so the
+target set cannot silently drift from the machine-checked source of truth:
+
+- **`scripts/sql/capture-live-retrieval-rpcs.sql`** — `pg_get_functiondef` for
+  the exact `regprocedure` signatures of the retrieval functions currently
+  flagged `LIVE IS AHEAD` in `supabase/drift-allowlist.json` (7 as of
+  2026-07-13, now including `repair_strict_enrichment_gate_batch`, which post-dates
+  the 2026-07-12 fingerprint table above). Pinned `search_path = ''` so the
+  signatures match the allowlist / `schema_drift_snapshot()` rendering exactly.
+  Re-run it at execution time per Step 1 and reconcile against the fingerprints.
+- **`tests/forward-codify-retrieval-targets.test.ts`** — offline guard (runs in
+  `verify:cheap`) asserting that capture query's target set equals the allowlist
+  `LIVE IS AHEAD` retrieval entries, so reconciling a sibling (removing its
+  allowlist entry) forces a matching edit to the capture query and this file.
+
+The committed query covers **only** the `LIVE IS AHEAD` retrieval subset (its
+guard invariant). It is **not** the full codification set: the live-only
+(`unexpected_live`) and `(verify)` functions in the fingerprint table above —
+`get_visual_evidence_cards`, `run_visual_eval_case`, `run_all_visual_eval_cases`,
+`repair_enrichment_quality_batch`, `match_document_index_units_hybrid`,
+`match_document_memory_cards_hybrid[_v2]` — are captured from that table per
+Step 1, not from this query. The fingerprint table remains the point-in-time
+reference snapshot; the committed query is the maintained,
+always-in-sync-with-the-allowlist capture of its subset.

+-- capture-live-retrieval-rpcs.sql  (READ-ONLY)
+--
+-- Captures the VERBATIM live bodies of the retrieval RPCs that are still flagged
+-- "LIVE IS AHEAD" in supabase/drift-allowlist.json, so their definitions can be
+-- forward-codified into a migration + supabase/schema.sql WITHOUT hand-authoring
+-- them. These bodies are complex, have diverged in both directions (e.g. the
+-- fail-closed retrieval_owner_matches predicate was applied to live while live
+-- also grew richer multi-strategy candidate sets), and are under active
+-- concurrent multi-session editing — so only a verbatim capture is correct. A
+-- hand-written body is exactly what got migration 20260705210000 neutralized.
+--
+-- SCOPE: this covers ONLY the allowlist "LIVE IS AHEAD" retrieval subset — the
+-- guard-tested set (tests/forward-codify-retrieval-targets.test.ts). It is NOT
+-- the complete codification set. The runbook also codifies live-only
+-- (unexpected_live) and "verify" functions — get_visual_evidence_cards,
+-- run_visual_eval_case, run_all_visual_eval_cases, repair_enrichment_quality_batch,
+-- match_document_index_units_hybrid, match_document_memory_cards_hybrid[_v2].
+-- Capture those from the fingerprint table in
+-- docs/forward-codify-retrieval-rpcs-workorder.md, not here.
+--
+-- Full procedure: docs/forward-codify-retrieval-rpcs-workorder.md
+-- Backlog item 0: docs/database-drift-detection.md#reconciliation-backlog
+--
+-- HOW TO RUN — this is a provider action (it reads the live project); get
+-- explicit approval first and run it only when the live DB is QUIESCENT (no
+-- concurrent edits to these functions). It changes nothing — it only reads
+-- pg_proc. Run it via the Supabase Dashboard SQL editor, an approved
+-- service-role SQL path, or the Supabase MCP execute_sql tool.
+--
+-- Expect EXACTLY 7 rows back (one per target). A target that no longer resolves
+-- on live (renamed, dropped, or already reconciled) is filtered out and simply
+-- yields FEWER rows — the query does not error. If you get fewer than 7, find
+-- which with the "missing signatures" snippet in the work-order and reconcile
+-- the target set + allowlist before continuing.
+--
+-- search_path is pinned to '' so oid::regprocedure renders fully-qualified and
+-- matches the allowlist keys / schema_drift_snapshot() signatures exactly, and
+-- so pg_get_functiondef emits fully-qualified, replay-safe text (the same style
+-- as migrations 20260701140631 / 20260707000000). This is cosmetic, not
+-- correctness-critical: check:drift hashes pg_get_functiondef under search_path
+-- '' on both live and the schema.sql replay, so a verbatim body always hashes
+-- equal regardless of how it was rendered at capture time.
