AI-generated release-gate review, posted at the maintainer request. Code ACK 9ea2ed7: the unavailable RIPEMD-160 path now reports an inconclusive standard-Bails check instead of asserting a mismatch; a matching Bails-alpha SHA-256 identifier still wins; and the no-record fingerprint display plus explicit operator confirmation are unchanged. The new frozen-vector regression passes, both current GitHub package matrices are green (12/12 jobs), and the isolated #42/#45/#7/#51/#57/#46 composition plus this commit passes 918 tests at 5,142/5,200 source review lines. No code blocker found. This is not an authorship ACK: the agent-authored commit needs responsible human review and rewrite/squash before merge, and the stack must be refreshed after #7/#57/#46 integration.

Exact-head release-gate recheck: ACK da14e0d. The prior P1 is resolved: the runtime now distinguishes an unavailable RIPEMD-160 check from a mismatch, still allows the Bails-alpha SHA-256 match to win, and both docs/security/model.md and invariant 4 describe that degraded outcome. git diff --check is clean; the focused identity/identifier tests pass in normal and python -O modes (9/9 each). No additional code blocker found. This remains stacked after #46 and needs the responsible human to review/rewrite or squash the agent-authored commits when the final #57/#46 integration is settled.

Reassign the expected_fingerprint argument instead of copying it into a local, and give existing_secret its None default before the source checks instead of in an else branch. Behavior is unchanged. The installed package drops from 5161 to 5159 logical review lines, which keeps the integrated #7/#42/#57/#46/#80/#81 tip under the <5200 budget. Security: the record gate still runs before any card is generated or shown, and interrupts at that gate still raise _WalletSetupInterrupted. Validation: ruff check, ruff format --check, mypy src/codex32, and pytest (918 passed, with and without -O). Refs #81, #38.

Agent release-gate re-review: ACK fb8d671.
The refreshed runtime patch is unchanged from the reviewed Bails-availability fix, and the documentation conflict resolution preserves the current Core-native seed-source contract while adding the required “RIPEMD-160 unavailable = inconclusive, not mismatch” wording. The sole inline thread is resolved. Exact-head Python-package run 546 and Bitcoin Core wallet-fixture run 11 both succeeded; focused no-record/identity tests also passed normally and under python -O.
No remaining code-review blocker found. Integration/authorship policy remains: #80 follows #57 and its agent-authored commits should be human-reviewed/re-written or squashed before merge.

Codex current-head release-gate re-review: ACK a0ab769.
The current runtime change correctly separates “standard Bails check unavailable” from an identifier mismatch, while still allowing a Bails-alpha SHA-256 match to win. The security model and invariant describe that degraded outcome. The one inline finding is resolved. Exact-head Python-package run 662 and Bitcoin Core wallet-fixture run 33 both succeeded.
No code blocker found. These agent-authored commits still require responsible-human rewrite/squash before integration.

AI-assisted current-head review: ACK 3a35463. RIPEMD-160 absence is now explicitly inconclusive, SHA-256 alpha checking remains available, and the security docs match the behavior. Exact-head package and Core-fixture CI are green.

Codex current-head review at 3a35463: no findings. The Bails identifier check now distinguishes unavailable RIPEMD-160 from an actual mismatch, preserving the stronger checks when available.

@codex review Current head was mechanically restacked onto the refreshed audit stack after #57's documentation-only follow-up. Please review this exact head for correctness/regressions; the composed stack passes 941 tests normally and under |

AI-assisted current-head review, posted at the maintainer's request.
ACK 0157a97 for code/security review. The restack preserves the reviewed RIPEMD-160-unavailable behavior: standard Bails is reported inconclusive, alpha SHA-256 still checks, and the security model documents the degraded case. Core fixture CI passes; the fresh Python-package run is queued. No findings.

When RIPEMD-160 is unavailable, a valid standard Bails identifier cannot be checked. Preserve the Bails-alpha SHA-256 result and distinguish that inconclusive state from a completed identifier mismatch, so the no-record restore prompt does not claim the cards are wrong. Keep the independent fingerprint and explicit operator-confirmation boundary unchanged. Refs #79
The no-record restore flow can no longer claim a standard Bails identifier mismatch when RIPEMD-160 is unavailable. Record that platform-dependent inconclusive outcome in both the security model and invariant so reviewers can distinguish it from a completed comparison. Refs #79

AI-assisted current-head review: ACK 096b654. A missing RIPEMD-160 implementation is now represented as an unavailable standard-Bails check rather than a false mismatch, while the independent fingerprint confirmation and Bails-alpha SHA-256 check remain intact. The no-record fallback still requires explicit operator confirmation and does not treat the inconclusive identifier check as authentication. Exact-head Python-package and Bitcoin Core fixture CI are green and all review threads are resolved. No correctness or release blocker found.
Why
On a Python/OpenSSL build without RIPEMD-160, a valid standard Bails identifier is not checked, but the no-record restore prompt previously said the cards were wrong or mixed up. The frozen
d9k8vector reproduces this whenhashlib.new("ripemd160", ...)raisesValueError.Change
Report the standard Bails check as unavailable/inconclusive. Preserve the independent fingerprint and explicit no-record confirmation, and continue checking the Bails-alpha SHA-256 rule. Update the security model and invariant 4 to document that outcome.
Review shape
Current head
096b654is the same two reviewed #80 patches mechanically replayed directly onto current #99 (27f4cc6). Both stable patch IDs are unchanged; no behavior was rewritten during the restack. The prior inline finding remains resolved.Validation
Exact-head GitHub Python-package and Bitcoin Core wallet-fixture workflows are green. The composed refreshed stack through #95 also passes all 941 tests normally and all 941 under
python -O, Ruff, strict mypy, correction-constant verification, andgit diff --check.Human integration order is #57 → #105 → #99 → #80 → #81 → #95. These commits are agent-authored and require the repository's responsible-human review/rewrite or squash policy before merge.
