- attempt_ledger.ensure: relax gap-3 outcome NOT NULL on Postgres
(ALTER COLUMN outcome DROP NOT NULL, probe-gated); without it
every resume write on a gap-3-migrated PG table fails with
NotNullViolation. SQLite keeps NOT NULL (no such ALTER).
- db.PgCursor: PRAGMA table_info fake rows had the notnull flag
inverted (NO -> 0); now matches sqlite semantics (1 = NOT NULL).
No caller read row[3] before, so this was latent.
- ledger_onboarding: stale 'PG path unverified' notes updated to
point at the real-PG proof.
- tests: pragma_info notnull pin (fake driver) + _column_notnull
probe pins (fresh + gap-3 SQLite).
Proof: 28/28 checks on real Postgres 16.15 (see verification/
codex-task-attempts-pg-proof-20261106.md).
User decision 2026-11-05: unified schema, rejecting the rehearsal
runtime column-union workaround and a ledger rename. One definition
(cloud.attempt_ledger.TASK_ATTEMPTS_DDL, 12 columns) shared by
cloud.attempts and cloud.db.POSTGRES_SCHEMA; ensure builds the
unified table fresh and migrates old resume, gap-3 ledger, and
rehearsal shapes in place with rows intact. aggregate counts
ledger rows only (outcome NULL = resume row, never counted).
SQLite verified by 8 new tests; Postgres real-DB upgrade path
explicitly NOT verified (see batch summary). Local commit only:
no merge, no push, no deploy.
- cloud/evidence_binding.py: bind/validate/nonce single-use store;
release endpoint consumes nonce on first validated submission,
replay -> 409 evidence_replayed, stale/future -> 409
evidence_stale, partial -> 400, absent -> old path + label.
Binding blocks exact replay and stale evidence, NOT restamping
(unsigned evidence cannot prove content freshness).
- cloud/quota.py docstring: actual-only is the v2 integration
position (already converged in v1 base via fef09ae, NOT in
main); original PR semantics (#86 all-rows vs #90 actual-only)
still pending coordinator confirmation at merge time.
- cloud/ledger_onboarding.py: DDL checklist referencing
PG_DDL/PG_MARKER_DDL constants, read-only verify_ledger_ready
and ledger_setup_report; default stays OFF, PG DDL stays an
operator action (never claimed as executed).
- cloud/ledger_outbox.py + worker hook: ledger write failures
go to a JSONL outbox in addition to the log and can be
replayed; task outcome still unaffected (rule 7 kept),
audit fail-closed untouched -- asymmetry documented, not
silently changed.
- cloud/gate_verification.py: read-only verifier over an
injected reader (match/mismatch/skipped); live wiring in
merge/release is NOT possible on the current contract (no
repo/ref in body or task row, no guaranteed trusted token),
proven in the module header; no fake verification claimed.
- cloud/tests/test_v2_evidence.py: 18 new tests, all passing.
