Changes: Preserve incomplete work and blocker metadata for S00-022. This checkpoint does not mark implementation accepted. Validation: Session ended with status blocked. Blocker: Pinned libomemo.js@3.0.0 supplies real embedded WASM but is a different unaudited ratchet and excludes consumer SCE; no approved decision reconciles it with S00-022 retained audited engine/persistence requirement. Task: S00-022 Agent: auto-crypto-bcd7f2a71667 Role: crypto Action: claim Status: blocked Task title: Confirm or source a verified browser/WASM-capable OMEMO2 backend for the Web client endpoint

Agent: auto-crypto-bcd7f2a71667; role: crypto. Disposition: blocker; no backend accepted.
Registry connectivity works. Pinned libomemo.js@3.0.0 metadata query and validated HTTPS tarball inspection exit 0; SRI matches, archive 1,061,939 bytes. Browser ESM, UMD and worker bundles embed real 85,585-byte WASM (magic/hash checked only). Pinned README excludes consumer SCE and reports no formal third-party audit. Candidate is a different ratchet, not a verified browser port preserving existing native libsignal engine/session records. Existing unsupported probe again exits 2.

Exact obstacle: no approved backend strategy reconciles this concrete alternative with card's audited engine/persistence preservation and ENC-009/011. No browser known-answer full OMEMO2/SCE test, audit, migration or wire compatibility passed. No source/ADR edits made after identifying blocker; ADR 0003 remains proposed.
Required external input: architecture/security/product owner records one backend strategy: retained audited engine's maintained browser port with primary-source license/support/SCE path, or authorization to evaluate a named alternative with independent security assessment and explicit license/persistence migration route. Any changed preservation condition must be reviewed through plan workflow, not silently waived. No relaxation of ENC-003/009/011. Resolver records only this bounded decision; it does not implement crypto or mark S00-004/S00-022 complete. Fresh continuation may correct universal registry-absence/Signal-WASM assertions in ADR and evaluate approved pinned target. Reporter exits after escalation.
