Top 6 rev2 fixes

Fix 1 — Conflict handling split

Rev1: Single ALREADY_EXISTS status for any pre-existing row.

Rev2: Two distinct statuses:

• ALREADY_EXISTS_OK — key exists, value = incomex_council, description matches → idempotent success, skip INSERT.
• BLOCKED_EXISTING_CONFLICT — key exists but value or description differs → STOP, do NOT overwrite, report existing values for GPT/User decision.

Applied in: Phase 2 (pre-transaction check) AND Phase 3B (in-transaction recheck).

Fix 2 — Transaction-scoped advisory lock

Rev1: Session-level pg_try_advisory_lock() with manual pg_advisory_unlock() in Phase 6.

Rev2: Transaction-scoped pg_try_advisory_xact_lock() inside the BEGIN/COMMIT block. Lock auto-releases at COMMIT or ROLLBACK. Phase 5 reserved (no action needed). Eliminates risk of orphan lock if Agent crashes between INSERT and unlock.

Fix 3 — Verify before COMMIT

Rev1: INSERT → COMMIT → verify (post-commit). If verify fails, row already committed — damage done.

Rev2: INSERT → verify → COMMIT only if verify PASS. If verify fails → ROLLBACK → no committed damage. Phase 4 becomes post-commit confirmation (read-only sanity check).

Transaction flow:

BEGIN → lock → recheck → INSERT → verify → COMMIT (only if verify PASS)

Fix 4 — Mandatory execution log

Rev1: No execution log requirement.

Rev2: All phases logged to /opt/incomex/logs/p3d-pack1-phase5c2b-<timestamp>.log. Captures introspection, resolved columns, pre-existing state, lock result, insert/verify outcome, COMMIT/ROLLBACK, KB report upload status. RUN_STARTED_AT recorded at script start.

Fix 5 — updated_at verification robustness

Rev1: updated_at within last 60 seconds — brittle, fails if Agent is slow.

Rev2: updated_at IS NOT NULL AND updated_at >= RUN_STARTED_AT. Tied to actual script start time, not arbitrary window. Works regardless of execution duration.

Fix 6 — Rollback uses resolved column names

Rev1: Hardcoded DELETE FROM dot_config WHERE key = ... in rollback instructions and final response.

Rev2: Final response reports:

rollback_key_column=<resolved config_key column name>
rollback_key_value=vocab.publication_authority.incomex_council

SQL in rollback section uses <config_key> placeholder with note to use resolved name from Phase 1.
