Lands four T4d planning artifacts together:
1. v3-phase-15-t4d-3-g1-v2-read.md (NEW)
T4d-3 G-1 V2 read v0.2, QA-signed in conversation 2026-04-25.
Per architect Issue 2(a) ratification: G-1 docs land first;
implementation references the committed hash. Future T4d-3
commits should reference this commit's sha via:
Refs G-1 sign: <this-commit-sha>
2. v3-phase-15-t4d-forward-carry-checklist.md (NEW)
v0.2 — 19 active T4a/T4b/T4c invariants with risk grades and
per-batch focus rows. T4d-3 close gate inscribed
(CARRY-T4D-LANE-CONTEXT-001 option A or B); pre/with-T4d-3
doc fixes recorded.
3. v3-phase-15-t4d-qa-scenario-catalogue.md (NEW)
v0.1 — 9 QA component-scope scenarios mirroring T4c QA
Stage-1 discipline. 10 framework primitives surfaced for
sw's batch PRs.
4. v2-v3-contract-bridge-catalogue.md (UPDATED)
§3.3 inscriptions for T4d-locked invariants:
- INV-REPL-NO-PER-LBA-DATA-REGRESSION (round-43)
- INV-REPL-RECOVERY-STALE-ENTRY-SKIP-PER-LBA (round-43)
- INV-REPL-RECOVERY-COVERAGE-ADVANCES-ON-SKIP (round-44)
- INV-REPL-LIVE-LANE-STALE-FAILS-LOUD (round-44)
- INV-REPL-RECOVERY-COVERAGE-RESTART-SAFE (Option C)
- INV-REPL-LANE-DERIVED-FROM-HANDLER-CONTEXT (Q2 + round-46)
- INV-REPL-TRANSPORT-STORAGE-CONTRACT-ONLY (Q1+Q3 + T4d-1
strengthening)
- INV-REPL-CATCHUP-FROMLSN-IS-REPLICA-FLUSHED-PLUS-1
(T4d-3 G-1 §5)
- INV-REPL-CATCHUP-FROMLSN-FROM-ENGINE-STATE-NOT-PROBE
(T4d-3 G-1 §5)
- CARRY-T4D-LANE-CONTEXT-001 (named carry, T4e/post-G5)
INV-REPL-CATCHUP-WITHIN-RETENTION-001 status updated:
T4c downgrade → T4d-2+T4d-3 un-pin path.
Process rule inscribed (architect 2026-04-25):
G-1 sign docs land in seaweedfs FIRST; sw implementation in
seaweed_block references the committed G-1 hash via
"Refs G-1 sign: <sha>" per mini-plan §7.1 procedural binding.

sw-block
Private WAL V2 and standalone block-service workspace.
Purpose:
- keep WAL V2 design/prototype work isolated from WAL V1 production code in
weed/storage/blockvol - allow private design notes and experiments to evolve without polluting V1 delivery paths
- keep the future standalone
sw-blockproduct structure clean enough to split into a separate repo later if needed
Suggested layout:
design/: shared V2 design docsprototype/: code prototypes and experiments.private/: private notes, phase development, roadmap, and non-public working material
Repository direction:
- current state:
sw-block/is an isolated workspace insideseaweedfs - likely future state:
sw-blockbecomes a standalone sibling repo/product - design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
