wt 30f7f222d2 S00-021: Record verified browser OMEMO backend blocker for S00-004
Changes:
- Re-ran both committed probes unchanged (smoke exit 0 SMOKE_PASS; wasm-unsupported exit 2 UNSUPPORTED_BLOCKER) and recorded actual outputs in state/evidence/S00-021-auto-crypto-fcef9b6781bf.md.
- Verified on the reachable npm proxy that no maintained browser/WASM-capable OMEMO2 package exists: @signalapp/libsignal-client 0.105.0 is native-only (zero .wasm); @signalapp/libsignal, omemo-client, omemo-top, omemo-wasm, @converse/omemo are all E404.
- Wrote docs/decisions/0003-crypto-library.md (proposed) documenting the verified audited session/ratchet + persistence capability and the honest blocker for the browser/worker/WASM endpoint and OMEMO2 wire layer, with traceable primary sources.
- Wrote state/handoffs/S00-021.md with the reproducible next step for the S00-004 continuation.

Validation:
- smoke.mjs -> exit 0 (SMOKE_PASS, 631-byte record byte-for-byte reload).
- wasm-unsupported.mjs -> exit 2 (wasmFiles 0, native prebuilds only).
- npm view E404s confirmed against the same proxy that returns @signalapp/libsignal-client 0.105.0, so responses are genuine.
- make check: 72 tooling tests passed (OK).
- No source changes outside scope: experiments/** unchanged; only state/tasks.json (workflow metadata) plus the in-scope ADR. S00-004 stays blocked (honest blocker), not bypassed.

Handoff S00-021 - Browser OMEMO backend remediation

Agent: auto-crypto-fcef9b6781bf Role: crypto Status: submitted for review Original: S00-004; remediation: S00-021 (blocker cause: "Agent timed out; process terminated before escalation").

Result

Re-ran both committed probes unchanged (exit 0 SMOKE_PASS; exit 2 wasm-unsupported) and recorded the actual outputs. Documented the verified capability (audited session/ratchet engine + session-record persistence via @signalapp/libsignal-client, no homegrown ratchet) and the verified blocker (browser/worker/WASM endpoint and the OMEMO2 wire layer are not available from any maintained package on the reachable registry; Signal's WASM distribution @signalapp/libsignal is E404 there). Wrote docs/decisions/0003-crypto-library.md (proposed) with traceable primary sources and honest boundaries.

Outputs produced (all inside accepted scope)

  • docs/decisions/0003-crypto-library.md (proposed ADR).
  • state/evidence/S00-021-auto-crypto-fcef9b6781bf.md (this run's evidence).
  • No source changes elsewhere; experiments/0003-crypto-library/** unchanged.

Evidence (actual, this run)

  • node experiments/0003-crypto-library/session-probe/smoke.mjs -> exit 0, SMOKE_PASS (631-byte session record, byte-for-byte reload).
  • node experiments/0003-crypto-library/session-probe/wasm-unsupported.mjs -> exit 2, UNSUPPORTED_BLOCKER, wasmFiles: 0.
  • npm view on reachable proxy: @signalapp/libsignal-client = 0.105.0 (AGPL-3.0-only); @signalapp/libsignal, omemo-client, omemo-top, omemo-wasm, @converse/omemo = E404.

Honest status

S00-004 is NOT done; it remains blocked on the browser/worker/WASM OMEMO2 backend. This remediation documents that blocker truthfully so the next executor has a reproducible state and a clear next step, instead of re-doing research and timing out again. No requirement bypass; unsupported format recorded as blocker.

Next input for S00-004 continuation

  1. Confirm node experiments/0003-crypto-library/session-probe/smoke.mjs (0) and .../wasm-unsupported.mjs (2).
  2. Obtain a verified browser/WASM-capable OMEMO2 backend (real .wasm/web build with an OMEMO2/S ce-format mapping) and run a known-answer roundtrip in the web target; or
  3. Escalate with traceable upstream primary sources resolving ENC-009/ENC-011 client-endpoint encryption for the browser transport.
  4. Only then may acceptance-1 (legacy/OMEMO2 AND worker/wasm AND persistence) be re-evaluated; do not declare S00-004 done on the persistence+Ratchet part alone.
