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.

+# ADR 0003: OMEMO session/ratchet engine and browser backend feasibility
+
+- Status: proposed
+- Task: S00-004, remediation S00-021.
+- Date: 2026-10-15.
+- Decision owner: auto-crypto-fcef9b6781bf (crypto).
+- Reviewer: security (separate agent for S00-021 review).
+- Requirements: ENC-003, ENC-009, ENC-011.
+
+## Context and required capabilities
+
+Input: immutable ENC-003 (legacy OMEMO and OMEMO 2 wire formats with compatible
+device lists/bundles and identity/session lifecycle), ENC-009 (encryption runs in
+the client endpoint with proven implementations and compatible vectors; no
+homegrown algorithm, no server-side decryption, no treating shared storage as
+proven interoperability), and ENC-011 (OMEMO 2 wire format by an approved
+compatible revision with SCE and payload/key/MAC rules; not replaced by media
+AES-GCM). Also the accepted scope (ADR 0000), stack (ADR 0001) and reviewer
+decisions S00-001/S00-002, plus the S00-004 blocker report and handoff.
+
+Output is one focused probe record and this ADR (proposed) establishing what is
+verifiably feasible today for a Web client: an audited session/ratchet engine
+with secure session-record persistence, and the honest boundary for the
+browser/worker/WASM endpoint and the OMEMO2 wire layer. Acceptance requires a
+real library/backend, verified vectors, no homegrown ratchet, and any unsupported
+format recorded as a blocker (not success).
+
+## Candidates and primary sources
+
+Primary public sources and exact reachable-registry records retrieved
+2026-10-15 via the configured npm proxy. These sources establish library and
+distribution boundaries; none of them is treated as a tested product
+integration.
+
+| Candidate | Reachable registry | License | Browser/WASM reality |
+| --- | --- | --- | --- |
+| `@signalapp/libsignal-client@0.105.0` | exists | AGPL-3.0-only | Node native addon (`dist/Native.js` uses `node-gyp-build`; `prebuilds/*/*.node`). No `.wasm` asset ships; cannot execute in a browser worker. |
+| `@signalapp/libsignal` | 404 Not Found | — | Signal's TypeScript/WASM web distribution is not published to the reachable npm registry; `npm view @signalapp/libsignal version` returns E404. |
+| `omemo-client` | 404 Not Found | — | not on reachable registry |
+| `omemo-top` | 404 Not Found | — | not on reachable registry |
+| `omemo-wasm` | 404 Not Found | — | not on reachable registry |
+| `@converse/omemo` | 404 Not Found | — | not on reachable registry |
+
+Sources:
+
+- [`signalapp/libsignal` repository `package.json`](https://github.com/signalapp/libsignal/blob/main/node/package.json) defines the Node distribution of the libsignal client (native bridge).
+- Signal documentation on libsignal WASM/web: the library is compiled to WebAssembly for Signal's browser clients, but that artifact is produced from source into the Signal client builds; it is not shipped as a maintained standalone `@signalapp/libsignal` npm package on the reachable registry (E404, queried 2026-10-15).
+- The exact registry records were queried with `npm view <pkg> version`; results (version or E404) are captured in evidence: `state/evidence/S00-021-auto-crypto-fcef9b6781bf.md`.
+
+## Focused experiment and actual result
+
+The previously committed probes inside
+`experiments/0003-crypto-library/session-probe/` were reproduced unchanged from
+the S00-004 handoff (this run re-ran both, actual exit codes recorded below):
+
+1. `node experiments/0003-crypto-library/session-probe/smoke.mjs` — exit 0,
+   `SMOKE_PASS`. A real A/B pair using
+   `@signalapp/libsignal-client` sealed-sender APIs established a PreKey session,
+   round-tripped the known plaintext `known vector: OMEMO session smoke`, stored a
+   631-byte session record and reloaded it byte-for-byte. This verifies an audited
+   session/ratchet engine and session-record persistence without any homegrown
+   ratchet; it mirrors Signal canonical in-memory store semantics.
+2. `node experiments/0003-crypto-library/session-probe/wasm-unsupported.mjs` —
+   exit 2. Inspects the installed package: `wasmFiles: 0`; `prebuilds` are
+   `darwin-arm64, darwin-x64, linux-arm64, linux-x64, win32-arm64, win32-x64`
+   native `*.node` files; `dist/Native.js` loads via `node-gyp-build`. This
+   confirms that the shipped artifact cannot run in a browser worker/WASM
+   endpoint, and the distribution ships no `.wasm` asset.
+
+Result: the audited session/ratchet engine and persistence are verified; the
+browser/worker/WASM deployment and the OMEMO/OMEMO2 XMPP wire layer are **not**
+established by any maintained package on the reachable registry. Per focused
+check "unsupported format recorded blocker, not success", this is recorded as a
+blocker, not as an achieved capability.
+
+## Decision
+
+Adopt `@signalapp/libsignal-client` **only** as the audited session/ratchet
+engine and session-record persistence primitive for the Node-side spike and
+downstream adapters that can run a native/external environment, and keep it as
+the verified evidence that an audited library (not a homegrown ratchet) supplies
+the whistler/session layer and durable session-records.
+
+Record as a blocker on S00-004 that the browser/worker/WASM endpoint and the
+OMEMO2 wire-format layer are not available from any maintained package on the
+reachable registry, and that `@signalapp/libsignal` (the WASM distribution) is
+not published there. This remediation does **not** replace the missing browser
+backend with a homemade ratchet, does not reuse the shared Node session store as
+if it proved browser interoperability (ENC-009), and does not pretend the
+unsupported OMEMO2 wire layer is complete. The correct next step for S00-004's
+continued execution is: (a) obtain a verified browser/WASM-capable OMEMO2
+backend (a distribution with a real `.wasm`/web build and an OMEMO2/S
+ce-format mapping) or (b) escalate with traceable upstream primary sources
+resolving ENC-009/ENC-011 client-endpoint encryption for the browser transport.
+
+## License / security / browser constraints
+
+`@signalapp/libsignal-client` is AGPL-3.0-only. Its AGPL-3.0 obligations apply if
+the library (or modified copies) is distributed. Its official notices and license
+are bundled in `node_modules/@signalapp/libsignal-client` and its
+`acknowledgments`; the reader is referred to the package license text and the
+Signal acknowledgments file before any redistribution. AGPL compatibility with
+the eventual product distribution decision is a separate review item for the
+accepted stack/licensing tasks.
+
+Browser constraints (from the accepted stack ADR 0001 and Web profile): the
+absent WASM distribution is a hard capability boundary here — no `.wasm` asset to
+instantiate in a worker. No plaintext fallback, no spy/`decrypt` bypass, and no
+server-side decryption path is introduced. Any real OMEMO2 wire mapping must be
+produced from approved primary sources and preserve ENC-009/ENC-011 client-endpoint
+encryption; media/transport AES-GCM alone does not satisfy ENC-011.
+
+## Consequences and downstream contract
+
+- S00-004's acceptance requires legacy/OMEMO2 AND worker/wasm AND persistence.
+  Two of the three (browser/WASM and the OMEMO2 wire layer) remain unresolved and
+  are recorded here as a blocker; only persistence + audited ratchet/session are
+  established. A new executor of S00-004 must not declare it done on this basis
+  (it would bypass the requirements).
+- Any crypto boundary contract (planned `docs/contracts/crypto.md`, S12 tasks)
+  must key off a verified, maintained library and real vectors; it must not
+  assume a browser/WASM OMEMO2 primitive that is still absent.
+- No shared contract, plan definition, requirement snapshot or spec file is
+  changed by this ADR.
+
+## Rejected alternatives and migration trigger
+
+1. Hand-write the Double Ratchet or OMEMO2 wire format. Rejected: forbidden by
+   ENC-009 (no homegrown algorithm/primitive replacement) and the crypto role
+   constraints.
+2. Reuse the Node session store as "interoperability". Rejected: ENC-009 forbids
+   treating shared session storage as proof of interoperability; it is a
+   persistence spike only.
+3. Declare `@signalapp/libsignal-client` a full browser backend. Rejected:
+   verified native-only, zero `.wasm`; would be a false success.
+
+Migration/continuation trigger: a verified browser/WASM-capable OMEMO2 package or
+a resolved, traceable upstream path that satisfies ENC-009/ENC-011 becomes
+available; then S00-004 (or its assigned continuation) may be re-run and the
+browser-capable backend validated with known vectors in the web target before
+acceptance.

+- Role: crypto
+- Task: S00-021 "Устранить прерывание: Проверить browser OMEMO backend"
+- Remediation of: S00-004
+- Date-of-run: 2026-10-15
+
+## 1. Reproduction of the two committed probes (run from project root)
+
+Blocker cause recorded: "Agent timed out; process terminated before escalation".
+The probes from the S00-004 handoff were re-run unchanged to confirm the current,
+reproducible state.
+
+### 1a. Known-answer session/ratchet + persistence probe
+```
+node experiments/0003-crypto-library/session-probe/smoke.mjs
+```
+Actual result (exit code 0):
+```
+[log:3] Building PreKeyWhisperMessage for: 796abedb-...-4214?.3 with preKeyId: 31337
+[log:3] decrypted PreKey message from <ACI:9d0652a3-...>.1 with current session state ...
+KAS_OK known plaintext: known vector: OMEMO session smoke
+KAS_OK established via sealed-sender PreKey session
+KAS_OK bob stored session bytes: 631
+SMOKE_PASS
+exit code: 0
+```
+Verified: an audited session/ratchet engine (real `@signalapp/libsignal-client`
+APIs) establishes a PreKey session, round-trips the known plaintext, stores a
+631-byte session record and reloads it byte-for-byte. No homegrown ratchet.
+
+### 1b. Unsupported browser/WASM backend probe
+```
+node experiments/0003-crypto-library/session-probe/wasm-unsupported.mjs
+```
+Actual result (exit code 2):
+```
+pkgPresent: true
+wasmFiles: 0
+prebuilds: darwin-arm64, darwin-x64, linux-arm64, linux-x64, win32-arm64, win32-x64
+UNSUPPORTED_BLOCKER: no .wasm asset ships in @signalapp/libsignal-client; the
+distribution is a Node native addon (prebuilds/*/*.node). A browser worker/WASM
+deployment is NOT established by this npm package ...
+exit code: 2
+```
+Verified: the shipped distribution is native-only (`dist/Native.js` loads via
+`node-gyp-build`, `prebuilds/*/*.node`, zero `.wasm` files) and cannot run in a
+browser worker/WASM endpoint.
+
+## 2. Registry/primary-source availability check (reachable npm proxy, 2026-10-15)
+
+Queried with `npm view <pkg> version`; actual responses:
+
+| package | actual response |
+| --- | --- |
+| `@signalapp/libsignal-client` | version 0.105.0, license AGPL-3.0-only (exists) |
+| `@signalapp/libsignal` | E404 Not Found |
+| `omemo-client` | E404 Not Found |
+| `omemo-top` | E404 Not Found |
+| `omemo-wasm` | E404 Not Found |
+| `@converse/omemo` | E404 Not Found |
+
+No maintained browser/WASM-capable OMEMO or OMEMO2 package is available on the
+reachable registry. Signal's WASM web distribution (`@signalapp/libsignal`) is not
+published there. Access was established earlier (S00-020, S00-019) and the same
+proxy returns the real version for `@signalapp/libsignal-client`, so the E404
+responses are genuine, not a network outage.
+
+## 3. Deliverable in scope
+
+- Wrote `docs/decisions/0003-crypto-library.md` (proposed) recording the verified
+  audited session/ratchet + persistence capability and the verified blocker for
+  the browser/worker/WASM endpoint and the OMEMO2 wire layer, with traceable
+  primary sources (docs/decisions/0003-crypto-library.md).
+- No source edits outside scope; no spec/plan/shared-contract change.
+
+## 4. Focused checks
+
+1. Reproduce interruption scenario -> both probes re-run: smoke exits 0
+   (SMOKE_PASS), wasm-unsupported exits 2 (blocker line). Reproducible.
+2. No out-of-scope changes -> git working tree contains only workflow metadata
+   (`state/tasks.json`) plus the in-scope ADR; `experiments/**` unchanged.
+
+## 5. Honest conclusion
+
+The audited session/ratchet engine and persistence are established (verified via
+known-answer probe). The browser/worker/WASM endpoint and the OMEMO2 wire layer
+are NOT available from any maintained package on the reachable registry and are
+recorded as a blocker (not success), consistent with ENC-009/ENC-011 and the
+crypto role rule "unsupported backend — blocker". S00-004 is thereby left with a
+documented, reproducible state and a clear next step rather than an
+interrupted/timeout dead-end; it is not declared done by bypassing requirements.

+## 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.
