Hand-off doc v0.3 + G5 kickoff v0.2: m01+M02 bring-up smoke surfaced
that cmd/blockvolume binary lacks T4 replication wiring entirely.
Sw-confirmed root cause:
- --t1-readiness HealthyPathExecutor is primary-only by design
- volume.Config.ReplicationVolume slot exists (host.go:73) with godoc
"T4a-5 production wiring sets this" — but T4a-5 only added the
field; the wiring NEVER landed
- T4d-4 part B wired WithEngineDrivenRecovery() for component test
framework (cluster.go:357-369), NOT for the binary
- Result: V3 components compose end-to-end (proven by T4d HARD GATE
#3); the production binary still constructs a primary-only data
plane
Sw confirmed this is real implementation work (150-300 LOC + design),
not a 50-LOC quick patch. Four design decisions needed:
1. Role inference (assignment vs CLI flag vs topology)
2. Peer discovery (from AssignmentFact.Peers)
3. Listener lifecycle (--data-addr reuse + Stop)
4. Engine instantiation (one engine per volume)
G5 kickoff revised to v0.2:
- 5 batches → 6 batches (binary wiring promoted to G5-4)
- G5-1/2/3 are NOT blocked by G5-4 (component framework already
binds T4d-4 part B; QA scenarios + walstore cadence at
component/primary-only scope can run in parallel)
- G5-4 binary wiring: needs full governance loop (kickoff →
architect ratify → mini-plan → architect ratify → G-1 → code).
G-1 source: T4d-4 part B component framework as V3-native PORT
- G5-5 m01 hardware first-light DEPENDS on G5-4 (script can't
drive replica scenarios until binary supports replicas)
- G5-6 G5-DECISION-001 resolution at G5 close (was G5-5 in v0.1)

V2 Design
This directory currently contains both the active V2 design canon and a large set of working notes, migration packs, and historical comparison material.
Use this README as the navigation layer. If a document is not listed under
Core Canon, treat it as supporting or historical context rather than the
current source of truth.
Core Canon
These are the documents that define the current V2 model and should be read first.
v2-protocol-truths.md— the stable semantic rulesv2-sync-recovery-protocol.md— sync, keepup, catchup, and rebuild protocol meaningv2-rebuild-mvp-session-protocol.md— rebuild session contract and data/control lanesv2-automata-ownership-map.md— assignment, session, and projection ownershipv2-protocol-claim-and-evidence.md— claims and current proof posturev2-validation-matrix.md—Rebuild Ready,Restore Ready, andV2 Readygatesv2-capability-map.md— capability-to-proof-tier mappingv2-proof-and-retest-pyramid.md— proof layering and retest strategy
Implementation Guides
These help maintainers understand how the current model maps into code.

Validation And Rollout
These define how the active design is validated, staged, or operationalized.

Working Reference
These are still useful, but they are not the shortest route to the current truth.

Migration And Historical Working Set
These files are mostly valuable for reconstruction of design history, migration intent, or earlier prototype shapes. They should usually not be the first docs opened during current development.

Cleanup Rule
When a document is superseded, prefer:
- keeping one canonical file in
Core Canon - leaving older reasoning in
Migration And Historical Working Set - avoiding duplicate "read first" lists across many files
Future cleanup should physically move or archive files only after their inbound references are reviewed.
Execution Note
- active development tracking lives under
../.private/phase/ - current phase contract and slice packages live there rather than in this directory
The original project-level copies under learn/projects/sw-block/design/
remain as shared references for now.
