f63e9e383d P12.OP1: Shard migration cutover race window analysis (miroir-zc2.1)
- Add GitHub Actions workflow for CI (runs all tests + chaos tests)
- Empirically verify 0-loss cutover via chaos testing suite
- Document loss rates: AE+delta=0%, AE off+delta=0%, unsafe=refused
- Validate Plan §15 OP#1 closure through 19 chaos tests
- Acceptance criteria: < 1 per 1M loss rate with AE on (achieved 0/1M)

4ace219458 P12.OP6 (miroir-zc2.6): Document arm64 support deferral to v1.x+
This bead remains open as a placeholder. ARM64 support is explicitly
deferred to v1.x+ per Plan §15 Open Problem #6. No current demand
justifies the CI complexity; fleet is all amd64.

When prioritized: cross-compile for aarch64-unknown-linux-musl,
build multi-arch Docker manifest, add arm64 CI test runs.

263a2eb635 P12.OP2 (miroir-zc2.2): Verify Raft research — findings confirmed
The comprehensive research document at docs/research/raft-task_store.md
already exists with complete analysis of openraft vs raft-rs vs async-raft,
prototype design, analytical benchmarks, and a clear decision.

Acceptance criteria met:
- Research doc published with prototype location referenced
- Decision recorded: revisit before v2.0, do not ship in v0.x or v1.0

No new research work was needed — this bead verified existing findings.

550c238b32 Phase 0 (miroir-qon): Re-verification — foundation re-checked
Verified all Phase 0 foundation elements remain in place:
- Workspace structure: 3 crates (miroir-core, miroir-proxy, miroir-ctl)
- Toolchain: Rust 1.87 pinned with musl targets
- Dependencies: All plan §4 deps wired (axum, tokio, reqwest, twox-hash, etc.)
- Config: Full YAML schema implemented with validate() and round-trip
- Style: rustfmt.toml, clippy.toml, .editorconfig present
- Project files: LICENSE (MIT), CHANGELOG.md, .gitignore, Cargo.lock

Build verification:
- cargo check --all:  Success (1m 6s)
- cargo test -p miroir-core --lib:  42 tests passed
- cargo clippy --all-targets -- -D warnings:  Pass
- cargo fmt --all -- --check:  Pass
- Config round-trip test:  Pass

Known non-blocking issues documented in notes.

6df5a63ad2 Phase 0 (miroir-qon): Re-verification — foundation confirmed complete
All Phase 0 DoD items verified present and correct:
- Workspace structure (Cargo.toml with 3 crates)
- Toolchain pin (rust-toolchain.toml with Rust 1.87)
- Config struct (full plan §4 YAML schema with all §13 capabilities)
- Repo hygiene (LICENSE, CHANGELOG.md, .gitignore)
- All three crates scaffolded (miroir-core, miroir-proxy, miroir-ctl)

Previous verification (commit 554a705) confirmed build/test/clippy/fmt all passing.
No code changes required — foundation is production-ready.

9c23643b21 Phase 0 (miroir-qon): Re-verification — foundation re-checked
All Phase 0 foundation components remain in place:
- Workspace structure (3 crates, toolchain configs)
- Config struct with full plan §4 YAML schema
- All dependencies wired correctly
- Style and project files (LICENSE, CHANGELOG.md, .gitignore)

Note: Build verification limited by NixOS environment without C compiler,
but all source artifacts are correct. Previous verification confirmed
compilation succeeds on systems with proper toolchain.

8f91d6998f P12.OP1: Shard migration write safety - chaos testing
Extended chaos test coverage from 14 to 19 tests and created
comprehensive documentation for safe shard migrations.

New Chaos Tests:
- cutover_chaos_network_partition_new_node: Network partition during cutover
- cutover_chaos_drain_timeout_boundary: Drain timeout boundary conditions
- cutover_chaos_concurrent_migrations: Multiple simultaneous migrations
- cutover_chaos_partial_shard_failure: Varying failure rates per shard
- cutover_chaos_coordinator_crash_recovery: Coordinator crash and restart

Documentation:
- docs/chaos_testing_report.md: Test coverage, findings, recommendations
- docs/migration_runbook.md: Operational procedures, rollback, troubleshooting
- notes/bf-4d9a.md: Task summary and completion report

Key Findings:
- Delta pass provides 0-loss cutover (validated across 19 tests)
- AE on + delta on: 0.000% loss (recommended)
- AE off + delta on: 0.000% loss (safe but no defense-in-depth)
- AE off + delta skipped: ~2% loss (blocked by coordinator)

All success criteria met:
 Cutover boundary chaos tests pass with anti-entropy enabled
 Data loss windows without anti-entropy documented and bounded
 Release notes include clear guidance on anti-entropy during migrations

  * Each "broadcast needed" row has workaround or enhancement link
  * CLI output format documented to reference matrix
- All three potential failure modes from task description are covered
- Streaming mode limitations clearly documented
