Changes:
- Wrote state/evidence/S00-021-review.md recording independent re-checks of the
executor's remediation for S00-004's interruption ("Agent timed out before
escalation").
- Reproduced both committed probes unchanged: smoke.mjs exit 0 (SMOKE_PASS,
631-byte session record byte-for-byte reload) and wasm-unsupported.mjs exit 2
(wasmFiles 0, native-only prebuilds), matching executor evidence exactly.
- Independently re-queried npm registry: @signalapp/libsignal (browser WASM) E404;
@signalapp/libsignal-client 0.105.0 (native, AGPL-3.0) exists; confirms the
browser/worker/WASM + OMEMO2 wire-layer blocker is genuine.
- Audited scope via git: commit 30f7f22 touches only the in-scope ADR
docs/decisions/0003-crypto-library.md plus workflow metadata; experiments/**
unchanged; working tree clean. No requirement bypass: S00-004 remains blocked,
ADR 0003 records the honest blocker and forbids done on persistence+Ratchet alone.
Validation:
- make check: 72 tooling tests OK.
- Both probes reproduced, exit codes and output match evidence.
- Acceptance met: interruption repro row exists for next executor; original not
declared done via bypass.

# S00-021 - Review evidence (security reviewer)
|
|
|
|
- Reviewer agent: `auto-security-5d2ae592b569`
|
|
- Role: security
|
|
- Task: S00-021 (remediation of S00-004)
|
|
- Owner (executor): `auto-crypto-fcef9b6781bf`
|
|
- Date: 2026-10-15
|
|
- Result: **APPROVE**
|
|
|
|
## Scope of review
|
|
|
|
Verify the executor removed the stated interruption cause ("Agent timed out; process
|
|
terminated before escalation") by reproducibly proving S00-004 readiness, without a
|
|
requirement bypass. Read: handoff, blocker, ADR 0003, evidence, task card, allowed paths.
|
|
|
|
## Independent re-checks performed
|
|
|
|
### 1. Reproduction of the two committed probes (run unchanged from project root)
|
|
|
|
- `node experiments/0003-crypto-library/session-probe/smoke.mjs`
|
|
Actual: exit code 0, `SMOKE_PASS`. Matches evidence: `KAS_OK known plaintext`,
|
|
631-byte session record stored and reloaded byte-for-byte via
|
|
`@signalapp/libsignal-client` sealed-sender PreKey APIs (audited engine, no
|
|
homegrown ratchet).
|
|
- `node experiments/0003-crypto-library/session-probe/wasm-unsupported.mjs`
|
|
Actual: exit code 2, `UNSUPPORTED_BLOCKER`, `wasmFiles: 0`, prebuilds are native
|
|
`*.node` (`darwin-arm64 ... win32-x64`). Matches evidence: no `.wasm` ships; the
|
|
distribution cannot run in a browser worker/WASM endpoint.
|
|
|
|
Both probes reproduce the evidence exactly. The interruption scenario is therefore
|
|
reproducibly re-established rather than dissimulated.
|
|
|
|
### 2. Registry availability (independent, public npm registry, this run)
|
|
|
|
- `npm view @signalapp/libsignal version` -> E404 Not Found (WASM web distribution
|
|
not published to reachable registry). Confirms evidence.
|
|
- `npm view @signalapp/libsignal-client version` -> 0.105.0 (native addon; AGPL-3.0).
|
|
Confirms evidence and that the E404 is genuine (same proxy serves the real version).
|
|
|
|
### 3. Scope audit (git)
|
|
|
|
- `git status`: working tree clean after the executor commit; nothing uncommitted.
|
|
- `git show --stat HEAD` (30f7f22): changed files are only the in-scope ADR
|
|
`docs/decisions/0003-crypto-library.md` plus workflow metadata
|
|
(evidence, handoff, commit message, `state/tasks.json`, generated matrices/cards).
|
|
- `experiments/0003-crypto-library/**` unchanged (no commit touches it).
|
|
Full scope compliance with allowed paths; no spec/plan/shared-contract/source edits.
|
|
|
|
### 4. ADR content and honesty
|
|
|
|
`docs/decisions/0003-crypto-library.md` (proposed) states precise capabilities and
|
|
boundaries with traceable primary sources. It adopts `@signalapp/libsignal-client`
|
|
only as the audited session/ratchet + persistence primitive for the Node-side spike,
|
|
and records the browser/worker/WASM endpoint + OMEMO2 wire layer as a blocker (not
|
|
success). No homegrown algorithm, no plaintext fallback, no server-side decryption
|
|
path is introduced. S00-004 is left blocked; the ADR explicitly forbids declaring it
|
|
done on the persistence+Ratchet part alone, preserving ENC-009/ENC-011.
|
|
|
|
### 5. Foundation integrity
|
|
|
|
`make check` -> 72 tooling tests, OK (exit 0). Confirms executor's claim.
|
|
|
|
## Acceptance assessment
|
|
|
|
1. Interruption cause reproducibly resolved: probe scenario reproduces exactly as
|
|
documented and the browser/WASM OMEMO2 blocker is truthfully recorded for the next
|
|
executor (not a timeout dead-end). PASS.
|
|
2. No requirement bypass: S00-004 not declared done; blocker preserved; no fake success.
|
|
PASS.
|
|
|
|
## Conclusion
|
|
|
|
Unit-of-outcome met the card acceptance and focused checks; all evidence independently
|
|
confirmed; scope clean. APPROVE.
|
|
|
|
## Communications
|
|
|
|
- Executor commit message (30f7f22) accurately matches the actual diff and checks;
|
|
no fabricated results found. |
