S00-022: Record blocked task and remediation handoff

Changes: Preserve incomplete work and blocker metadata for S00-022. This checkpoint does not mark implementation accepted.
Validation: Session ended with status blocked.
Blocker: All ten live npm metadata queries fail with EAI_AGAIN resolving the configured proxy, including the known libsignal-client control. Required release and artifact verification for S00-022 cannot proceed; failures are not E404 evidence.

Task: S00-022
Agent: auto-crypto-316a193d6c3e
Role: crypto
Action: claim
Status: blocked

Task title: Confirm or source a verified browser/WASM-capable OMEMO2 backend for the Web client endpoint

+# S00-022 evidence — registry connectivity blocker
+
+Agent: auto-crypto-316a193d6c3e; role: crypto; date: 2026-10-15.
+
+Input: S00-022 card, ENC-003/009/011, ADRs 0000–0003, direct-dependency evidence and S00-004/S00-021 handoffs. Intended output: one traceable browser OMEMO2 backend decision. Acceptance requires verified web artifacts and compatible wire evidence or an approved external sourcing decision; neither is established this run.
+
+## Actual checks
+
+- `python3 scripts/tasks.py resume --agent auto-crypto-316a193d6c3e`: exit 0; assigned S00-022 in_progress. `python3 scripts/tasks.py show S00-022`: exit 0; scope only ADR 0003 plus workflow metadata.
+- `node experiments/0003-crypto-library/session-probe/wasm-unsupported.mjs`: exit 2, pkgPresent true, wasmFiles 0; six native prebuild platforms listed. This confirms only the installed package distribution boundary. Absence of standalone .wasm files is not a general test for absence of embedded WASM in other packages.
+- Ten independent subprocess calls, each `npm view <package> version license dist-tags --json --fetch-retries=0 --fetch-timeout=15000 --cache=/tmp/luma-s00-022-npm-cache`: each exit 1, JSON error code EAI_AGAIN, getaddrinfo failure for the configured proxy. Packages: @signalapp/libsignal-client, @signalapp/libsignal, @converse/omemo, @xmpp/omemo, omemo2, omemo-js, omemo-client, omemo-top, omemo-wasm, libomemo.js. No E404 or live version was reproduced. No credentials or private environment values captured in this report.
+
+## Primary-source discovery (web tool; not execution evidence)
+
+[Converse upstream README](https://github.com/conversejs/libomemo.js) describes a browser/worker candidate with embedded WASM and OMEMO2 ratchet support. It explicitly leaves SCE payload encryption to consumers and states there is no formal third-party audit. [Upstream package manifest](https://raw.githubusercontent.com/conversejs/libomemo.js/master/package.json) shows version 3.0.0 and GPL-3.0. These moving upstream pages are leads, not a pinned installed artifact, maintenance assurance, license acceptance or verified end-to-end result. The earlier universal claim that no maintained registry package exists is not established by queries of a few guessed names. Likewise the earlier ADR claim of a Signal browser WASM distribution lacks a specific supporting source and is not reaffirmed.
+
+## Limits and disposition
+
+Registry connectivity blocks required live metadata/artifact verification. No browser OMEMO2 known-answer roundtrip, nonzero candidate WASM footprint, session migration, persistence compatibility or SCE payload/key/MAC mapping was verified. Existing Node smoke was not rerun; previous audit/persistence claims are historical evidence, not newly certified. No candidate installed, no source/ADR/spec/contract edited, no encryption bypass. Stop and escalate one network remediation; the subsequent fresh S00-022 executor must investigate the candidate and remaining acceptance after connectivity is independently restored.
