feat: Phase 20 acceptance fixes + sw-test-runner suite mode
Acceptance rows closed: - WriteLBA/SyncCache contract: code comments document write-back vs durability fence semantics - RF=2 stable identity: v2bridge always uses SetReplicaAddrs (preserves ServerID); blockcmd dispatcher also fixed to use setupPrimaryReplicationMulti; test asserts exact expected ReplicaID="vs-2" (not just non-empty) - Tests treating WriteLBA as commit: replica_read_test rewritten with SyncCache as durability fence - publish_healthy contract: 3 gate tests with hard assertions including gate 3 (PrimaryShipperConnected) - SetReplicaAddr deprecation warning added - WALShipper.ReplicaID() getter added for identity verification Test runner enhancements: - sw-test-runner suite command: build → deploy → run N scenarios in one invocation with --skip-deploy support - Suite YAML definitions for T6 Stage 0 and Stage 1 - deploy action: kill stale processes, clean dirs, cross-compile, upload - run-phase20-t6.ps1 PowerShell script (deprecated by suite command) Engine/runtime fixes: - Recovery executor nil-safety improvements - Recovery bundle BuildRecoveryBundle defensive checks - ShipperGroup MinReplicaFlushedLSNAll surface Docs: acceptance checklist refined, test matrix updated, T6 runbook, engine maintainer tutorial, design README updated. 26 files changed, ~1600 insertions.

# Phase 20 Product Acceptance Checklist
|
||||
|
||||
Date: 2026-04-06
|
||||
Status: active
|
||||
Status: closure implemented; tester validation pending

||||
|
||||
## Reading
|
||||
|
||||
`Phase 20` is now architecture-complete but not yet product-complete.
|
||||
`Phase 20` is now architecture-complete and the targeted host/runtime closure
|
||||
slice has been implemented for the bounded `RF=2 sync_all` acceptance path.
|
||||
|
||||
The V2 engine already has a product-shaped semantic contract. The remaining
|
||||
acceptance gap is host/runtime closure:
|
||||
acceptance work in this document was host/runtime closure:
|
||||
|
||||
1. `write` vs `flush` vs `durability` is not fully explicit
|
||||
2. fresh replica bootstrap is not fully protocol-aware
|
||||
3. host observations are not yet a complete protocol seam
|
||||
4. serving/publish boundaries are not yet derived from one closed contract
|
||||
5. some adapter and test paths still reflect pre-product assumptions
|
||||
1. make `write` vs `flush` vs `durability` explicit
|
||||
2. close fresh replica bootstrap as a bounded protocol session
|
||||
3. centralize host observations back into one protocol seam
|
||||
4. derive serving/publish boundaries from one closed contract
|
||||
5. remove pre-product assumptions from adapter and proof paths
|
||||
|
||||
As of this update, the hard-blocker closure set below has been implemented and
|
||||
retested on the bounded acceptance subset named by this checklist. This does
|
||||
not automatically mean every broader `weed/server` or master/integration suite
|
||||
outside the bounded `Phase 20` acceptance scope has been reclassified yet.
|
||||
|
||||
Interpret the current state in two layers:
|
||||
|
||||
1. implementation closure: the bounded host/runtime contract is now wired and developer-validated on the named proof subset
|
||||
2. acceptance closure: still requires tester validation and regression-grade test case freezing before the strongest product claim should be made
|
||||
|
||||
## Closure Update
|
||||
|
||||
The following closure points are now in place on the bounded acceptance path:
|
||||
|
||||
1. `WriteLBA()` is documented and used as write-back admission only
|
||||
2. `SyncCache()` is the explicit durability fence for `sync_all`
|
||||
3. fresh and late-attached replicas replay retained WAL backlog before live tail
|
||||
4. catch-up progress and classified failure now re-enter the core event seam
|
||||
5. `publish_healthy` and serving gates remain derived from core-owned protocol truth
|
||||
6. scalar identity paths now fail closed instead of synthesizing address-derived replica IDs
|
||||
|
||||
Focused verification used for this closure pass:
|
||||
|
||||
1. `go test ./weed/storage/blockvol/test/component -run "TestBootstrap_|TestPublishHealthy_|TestReplicaReadAfterShip"`
|
||||
2. `go test ./weed/server -run "TestP16B_RunCatchUp_UpdatesCoreProjectionFromLiveRecovery|TestBlockService_(CollectBlockVolumeHeartbeat_PrimaryPublishHealthyUsesCoreTruth|ReadinessSnapshot_PrefersCorePublicationHealth|ApplyAssignments_PrimaryScalarReplicaAddrWithoutServerID|ApplyAssignments_PrimaryRole_UsesCoreStartRecoveryTaskForCatchUp|NeedsRebuildObserved_InvalidatesOnlyTargetReplica)|TestP10P1_"`
|
||||
|
||||
## Validation Status
|
||||
|
||||
Use the following interpretation for every row in this checklist:
|
||||
|
||||
1. `Implemented`: code path is present and intended semantics are enforced
|
||||
2. `Developer-validated`: targeted unit/component/server proof exists and passed in this closure pass
|
||||
3. `Tester-validated`: named acceptance case has been run by tester or runner and is frozen as regression evidence
|
||||
|
||||
Current `Phase 20` reading:
|
||||
|
||||
1. the hard-blocker closure set is `Implemented`
|
||||
2. the hard-blocker closure set is `Developer-validated` on the bounded acceptance subset
|
||||
3. the hard-blocker closure set is not yet globally `Tester-validated` just because the developer proof passed
|
||||
4. tester automation now has a metadata-driven suite entry for `Stage 0`, but the current hardware run still fails at the known first-write `dd_write` / `sync_all` barrier issue, so acceptance remains pending
|
||||
|
||||
## Tester Validation Still Required
|
||||
|
||||
Even for rows that are already closed by implementation, tester validation is
|
||||
still required before treating the closure as durable acceptance evidence.
|
||||
|
||||
Minimum tester-side acceptance cases to freeze:
|
||||
|
||||
1. `WriteLBA != durability`: plain write return must not be used as commit proof; `SyncCache()` / `sync_all` remains the durability fence
|
||||
2. fresh replica bounded catch-up: `freeze -> replay -> target reached -> live enable`
|
||||
3. late attach no-gap path: retained WAL backlog must be shipped before current live tail
|
||||
4. catch-up fail-closed classification: timeout and retention loss must stop catch-up and re-enter rebuild escalation semantics
|
||||
5. `publish_healthy` contract: transport contact alone must not produce healthy publication without recovery and durability closure
|
||||
6. stable identity fail-closed: missing `ServerID` must reject or degrade identity closure rather than deriving identity from address shape
|
||||
|
||||
Tester evidence should be recorded as named cases in `phase-20-test.md`,
|
||||
testrunner scenarios, or equivalent acceptance artifacts so the closure is not
|
||||
only "currently believed" but regression-frozen.
|
||||
|
||||
Current tester status:
|
||||
|
||||
1. the metadata-driven suite pipeline now runs end-to-end: build, deploy, remote scenario execution, and evidence collection
|
||||
2. `P20-H0` currently starts and runs remotely, but the first hardware run still fails in `record-before` on the known first-write `dd_write` path
|
||||
3. this means tester infrastructure is now real and reusable, but `Stage 0` is not yet a passing acceptance artifact

# Phase 20 T6 Runbook
|
||||
|
||||
Date: 2026-04-06
|
||||
Status: active
|
||||
|
||||
## Purpose
|
||||
|
||||
This runbook turns `Phase 20 T6` into an executable hardware-validation
|
||||
program.
|
||||
|
||||
It is intentionally separate from `phase-20-test.md`.
|
||||
|
||||
`phase-20-test.md` defines the coverage matrix and staged closure model.
|
||||
This file answers the operational questions:
|
||||
|
||||
1. what exact command surface exists today
|
||||
2. which hardware scenarios should be run first
|
||||
3. what must be observed during `Stage 0`
|
||||
4. what is allowed before entering `V2` failover
|
||||
5. which software-side QA tests should stay aligned while hardware work proceeds
|
||||
|
||||
## Sources Of Truth
|
||||
|
||||
Primary references:
|
||||
|
||||
1. `sw-block/.private/phase/phase-20.md`
|
||||
2. `sw-block/.private/phase/phase-20-test.md`
|
||||
3. `weed/storage/blockvol/testrunner/cmd/sw-test-runner/main.go`
|
||||

||||

## T6 Runner Contract
|
||||
|
||||
### Real CLI Surface
|
||||
|
||||
Current runner entrypoint:
|
||||
|
||||
```bash
|
||||
sw-test-runner run <scenario.yaml> [flags]
|
||||
```
|
||||
|
||||
Important observation:
|
||||
|
||||
1. the current CLI exposes `run`, `validate`, `list`, `coordinator`, `agent`,
|
||||
and `console`
|
||||
2. it does **not** visibly expose a `run --all` mode in
|
||||
`weed/storage/blockvol/testrunner/cmd/sw-test-runner/main.go`
|
||||
|
||||
Practical consequence:
|
||||
|
||||
1. `T6` must use an explicit scenario pack
|
||||
2. `T7` full-suite wording should be interpreted as a scenario list or suite
|
||||
wrapper, not as an assumed built-in `--all` implementation
|
||||
|
||||
### Real Master Flag
|
||||
|
||||
The actual master CLI flag is:
|
||||
|
||||
```bash
|
||||
--block.v2Promotion
|
||||
```
|
||||
|
||||
This is defined in `weed/command/master.go`.
|
||||
|
||||
Use this spelling everywhere for `T6/T7`.
|
||||
|
||||
### How Promotion Mode Enters Runner-Launched Processes
|
||||
|
||||
`sw-test-runner` already supports passing arbitrary master and volume flags
|
||||
through scenario YAML:
|
||||
|
||||
1. `start_weed_master.extra_args`
|
||||
2. `start_weed_volume.extra_args`
|
||||
|
||||
That behavior is implemented directly in
|
||||
`weed/storage/blockvol/testrunner/actions/devops.go`.
|
||||
|
||||
### Contract By Stage
|
||||
|
||||
#### Stage 0
|
||||
|
||||
No promotion-mode toggle required.
|
||||
|
||||
Goal:
|
||||
|
||||
1. close the bootstrap membership gap on real hosts
|
||||
|
||||
#### Stage 1
|
||||
|
||||
Use:
|
||||
|
||||
```bash
|
||||
--block.v2Promotion=false
|
||||
```
|
||||
|
||||
But because `block.v2Promotion` already defaults to `false`, existing Stage 1
|
||||
scenarios can be used unchanged unless we want explicit traceability in copied
|
||||
YAMLs.
|
||||
|
||||
Recommended policy:
|
||||
|
||||
1. keep Stage 1 on existing YAMLs
|
||||
2. treat `V1` failover as the authority path
|
||||
3. use `V2` surfaces only as observation / diagnosis
|
||||
|
||||
#### Stage 2
|
||||
|
||||
Use:
|
||||
|
||||
```bash
|
||||
--block.v2Promotion=true
|
||||
```
|
||||
|
||||
Stage 2 must not rely on hidden defaults.
|
||||
|
||||
Recommended policy:
|
||||
|
||||
1. use dedicated Stage 2 YAML copies or overlays
|
||||
2. append `-block.v2Promotion=true` to `start_weed_master.extra_args`
|
||||
3. keep the rest of the scenario unchanged where possible so V1/V2 results stay
|
||||
comparable
|
||||
|
||||
Do not hand-edit running commands outside the scenario definition.
|
||||
Keep the toggle visible in scenario source or in a wrapper-generated temp copy.
|
||||
|
||||
## Stage 0 Bootstrap Closure Checklist
|
||||
|
||||
`Stage 0` is the current hard gate before meaningful `V2` failover hardware
|
||||
validation.
|
||||
|
||||
The blocker observed on hardware is:
|
||||
|
||||
1. promoted primary still shows `ReplicaIDs=[]`
|
||||
2. `RoleApplied=true`
|
||||
3. `ShipperConfigured=false`
|
||||
4. mode remains stuck before `publish_healthy`
|
||||
|
||||
### Required Observation Surfaces

#### VS-local debug surface
|
||||
|
||||
Use:
|
||||
|
||||
```bash
|
||||
curl http://<volume-admin-host>:<volume-admin-port>/debug/block/shipper
|
||||
```
|
||||
|
||||
Primary fields to read from each volume item:
|
||||
|
||||
1. `core_projection.replica_ids`
|
||||
2. `shipper_configured`
|
||||
3. `shipper_connected`

8. `receiver_ready`
|
||||
9. `executed_core_commands`
|
||||
10. `projection_mismatches`
|
||||
|
||||
This surface is backed by `weed/server/volume_server_block_debug.go`.
|
||||
|
||||
#### Master volume surface
|
||||
|
||||
Use:
|
||||
|
||||
```bash
|
||||
curl http://<master-host>:<master-port>/block/volume/<volume-name>
|
||||
```
|
||||
|
||||
Primary fields to read:
|
||||
|
||||
1. `volume_server`
|
||||
2. `epoch`
|
||||
3. `volume_mode`
|
||||
4. `engine_projection_mode`
|
||||
5. `cluster_replication_mode`
|
||||
6. `health_state`
|
||||
7. `replicas`
|
||||
|
||||
This surface is backed by `weed/server/master_server_handlers_block.go`.
|
||||
|
||||
#### Master status surface
|
||||
|
||||
Use:
|
||||
|
||||
```bash
|
||||
curl http://<master-host>:<master-port>/block/status
|
||||
```
|
||||
|
||||
Use this for summary corroboration only:
|
||||
|
||||
1. `healthy_count`
|
||||
2. `degraded_count`
|
||||
3. `unsafe_count`
|
||||
4. `failovers_total`
|
||||
5. `promotions_total`
|
||||
|
||||
### Stage 0 Pass Criteria
|
||||
|
||||
Healthy RF2 path must show all of the following:
|
||||
|
||||
1. promoted primary `core_projection.replica_ids` is not empty
|
||||
2. promoted primary `shipper_configured=true`
|
||||
3. promoted primary reaches `publish_healthy=true`
|
||||
4. promoted primary local `mode` reaches `publish_healthy`
|
||||
5. master `engine_projection_mode` reflects the local serving truth
|
||||
6. master `cluster_replication_mode` returns to a healthy cluster judgment
|
||||
7. no persistent `projection_mismatches` remain for the healthy path
|
||||
|
||||
### Stage 0 Fail Criteria
|
||||
|
||||
Any one of the following keeps `Stage 0` open:
|
||||
|
||||
1. `ReplicaIDs=[]` on the healthy promoted primary path
|
||||
2. `shipper_configured=false` after recovery to a supposedly healthy topology
|
||||
3. `publication_reason` still explains a missing shipper / missing replica while
|
||||
the cluster is otherwise healthy
|
||||
4. master says the cluster is healthy while the promoted primary still lacks
|
||||
replica membership
|
||||
5. local mode stays `allocated_only` or `bootstrap_pending` after the topology
|
||||
should have converged
|
||||
|
||||
### Minimum Operator Loop
|
||||
|
||||
When iterating on the fix, record this sequence each run:
|
||||
|
||||
1. before failure: `block/volume/<name>` and `/debug/block/shipper`
|
||||
2. immediately after failover: same two surfaces
|
||||
3. after expected recovery window: same two surfaces again
|
||||
4. note whether `ReplicaIDs`, `ShipperConfigured`, and `publish_healthy`
|
||||
converged together or diverged
|
||||
|
||||
## Stage 1 Scenario Pack
|
||||
|
||||
Stage 1 means:
|
||||
|
||||
1. failover authority stays on `V1`
|
||||
2. `V2` surfaces must stay coherent and conservative
|
||||
3. no semantic collapse is allowed between local, cluster, and legacy views
|
||||
|
||||
### Pack Definition
|
||||
|
||||
| Pack ID | Scenario | Why it is in Stage 1 |
|
||||
|---|---|---|
|
||||
| `P20-T6-H1A` | `weed/storage/blockvol/testrunner/scenarios/internal/recovery-baseline-failover.yaml` | primary death, auto-failover, data continuity, easiest baseline |
|
||||
| `P20-T6-H1B` | `weed/storage/blockvol/testrunner/scenarios/internal/suite-ha-failover.yaml` | HA failover with real cluster lifecycle and post-failover health checks |
|
||||
| `P20-T6-H1C` | `weed/storage/blockvol/testrunner/scenarios/cp11b3-manual-promote.yaml` | manual promote / preflight surface / publish recovery after rejoin |
|
||||
| `P20-T6-H1D` | `weed/storage/blockvol/testrunner/scenarios/lease-expiry-write-gate.yaml` | confirms write-gate semantics stay intact while T6 work proceeds |
|
||||
|
||||
### Stage 1 Execution Rules
|
||||
|
||||
1. use existing YAMLs unchanged
|
||||
2. do not enable `--block.v2Promotion=true`
|
||||
3. capture `block/volume/<name>` before and after failover
|
||||
4. capture `/debug/block/shipper` on both candidate servers during the run
|
||||
|
||||
### Stage 1 Must Prove
|
||||
|
||||
#### `P20-T6-H1A recovery-baseline-failover`
|
||||
|
||||
Must prove:
|
||||
|
||||
1. V1 auto-failover still succeeds
|
||||
2. epoch advances
|
||||
3. data remains readable after failover
|
||||
4. V2 surfaces honestly show whether the promoted node is complete or still
|
||||
bootstrap-limited
|
||||
|
||||
#### `P20-T6-H1B suite-ha-failover`
|
||||
|
||||
Must prove:
|
||||
|
||||
1. HA failover path still works on the real cluster
|
||||
2. `cluster_replication_mode` degrades conservatively after primary loss
|
||||
3. post-failover `engine_projection_mode` does not get confused with cluster
|
||||
health
|
||||
|
||||
#### `P20-T6-H1C cp11b3-manual-promote`
|
||||
|
||||
Must prove:
|
||||
|
||||
1. promotion preflight and promote APIs remain diagnosable
|
||||
2. restart / rejoin can return the cluster to `publish_healthy`
|
||||
3. manual promote path still carries the expected data continuity guarantee
|
||||
|
||||
#### `P20-T6-H1D lease-expiry-write-gate`
|
||||
|
||||
Must prove:
|
||||
|
||||
1. lease gate semantics still work during T6 work
|
||||
2. a seemingly healthy local target does not bypass lease safety
|
||||
|
||||
### Stage 1 Command Form
|
||||
|
||||
One scenario at a time:
|
||||
|
||||
```bash
|
||||
sw-test-runner run weed/storage/blockvol/testrunner/scenarios/internal/recovery-baseline-failover.yaml --results-dir results/phase20-t6/stage1/recovery-baseline-failover
|
||||
```
|
||||
|
||||
Preferred suite pack:
|
||||
|
||||
```bash
|
||||
sw-test-runner suite weed/storage/blockvol/testrunner/suites/phase20-t6-stage1.yaml
|
||||
```
|
||||
|
||||
Legacy compatibility wrapper:
|
||||
|
||||
```powershell
|
||||
powershell -File weed/storage/blockvol/testrunner/scripts/run-phase20-t6.ps1 -Stage stage1
|
||||
```
|
||||
|
||||
## Stage 2 Readiness Pack
|
||||
|
||||
Stage 2 means the system is ready to test real `V2` failover authority.
|
||||
|
||||
It is not just "same scenarios with one flag flipped."
|
||||
|
||||
### Hard Readiness Gates
|
||||
|
||||
Do not enter Stage 2 until all are true:
|
||||
|
||||
1. `Stage 0` bootstrap closure is passing on hardware
|
||||
2. proto regeneration is complete for evidence transport
|
||||
3. real evidence RPC is wired, not just a placeholder querier
|
||||
4. master startup path can visibly enable `--block.v2Promotion=true`
|
||||
5. operator surfaces can distinguish:
|
||||
- `disabled`
|
||||
- `placeholder_fail_closed`
|
||||
- `transport_ready`
|
||||
|
||||
### Stage 2 Scenario Set
|
||||
|
||||
| Pack ID | Scenario source | What it must prove |
|
||||
|---|---|---|
|
||||
| `P20-T6-H2` | Stage 1 failover baseline copied with `-block.v2Promotion=true` | durability-first selection on real hosts |
|
||||
| `P20-T6-H3` | dedicated ambiguous-evidence scenario | missing / partial / stale evidence fails closed |
|
||||
| `P20-T6-H4` | `v2-failover-gate.yaml` | promoted node stays gated until recovery truth allows serving |
|
||||
|
||||
### Stage 2 YAML Policy
|
||||
|
||||
Use dedicated Stage 2 copies or overlays for scenarios that start a master.
|
||||
|
||||
Required edit pattern:
|
||||
|
||||
1. preserve the original scenario flow
|
||||
2. append `-block.v2Promotion=true` to `start_weed_master.extra_args`
|
||||
3. do not fold the `V2` toggle into unrelated volume or target arguments
|
||||
|
||||
### Stage 2 Must Prove
|
||||
|
||||
1. fresh evidence, not heartbeat cache, decides promotion
|
||||
2. higher `CommittedLSN` wins over nicer-looking health
|
||||
3. partial evidence loss causes no promotion
|
||||
4. ineligible promoted nodes do not serve
|
||||
5. recovery can later re-enable serving when truth improves
|
||||
|
||||
## Stage 3 Compare Pack
|
||||
|
||||
Stage 3 compares the same scenario family under `V1` and `V2` failover.
|
||||
|
||||
Compare at least:
|
||||
|
||||
1. primary selected
|
||||
2. epoch behavior
|
||||
3. data continuity
|
||||
4. `engine_projection_mode`
|
||||
5. `cluster_replication_mode`
|
||||
6. gate / no-serve behavior
|
||||
7. whether divergence is explained by `V2` fail-closed semantics
|
||||
|
||||
## QA Alignment
|
||||
|
||||
Hardware validation should stay aligned with existing software-side QA tests.
|
||||
|
||||
| QA file | T6 relevance | Why it should stay in the loop |
|
||||
|---|---|---|
|
||||
| `weed/server/qa_block_cp11b3_adversarial_test.go` | preflight and promotion rejection surface | keeps failover rejection semantics pinned while Stage 2 transport is unfinished |
|
||||
| `weed/server/qa_block_cp13_9_mode_test.go` | mode vocabulary and transitions | prevents local / cluster / legacy surfaces from drifting semantically |
|
||||
| `weed/server/qa_failover_role_test.go` | auto-failover role handling, including different-path recovery | mirrors the kind of path-sensitive bug that can reappear on hardware |
|
||||
|
||||
Recommended T6 software companion run:
|
||||
|
||||
```bash
|
||||
go test ./weed/server/ -run "TestQA_T6_|TestCP13_9_|TestAutoFailover_" -count=1
|
||||
```
|
||||
|
||||
This does not replace hardware validation.
|
||||
It keeps semantic guardrails pinned while hardware work proceeds.
|
||||
|
||||
## Immediate Start Order
|
||||
|
||||
1. run `Stage 0` observation loop on the current baseline
|
||||
2. start fixing the replica-membership wiring gap until `Stage 0` closes
|
||||
3. run the `Stage 1` pack on existing YAMLs
|
||||
4. only after `Stage 0` is closed and evidence transport is real, prepare Stage 2 YAML copies
|
||||
|
||||
## What Not To Do
|
||||
|
||||
1. do not call `T6` started just because mode surfaces look richer
|
||||
2. do not enter `--block.v2Promotion=true` runs while evidence transport is still placeholder-only
|
||||
3. do not hide the promotion-mode toggle in ad hoc shell history
|
||||
4. do not treat `run --all` as available unless the runner actually implements it

## Acceptance Retest Overlay
|
||||
|
||||
The `T1-T5` roster above proves capability closure by layer.
|
||||
|
||||
`Phase 20` also needs a tester-owned acceptance overlay so the final product
|
||||
claim is not based only on developer proof. These acceptance cases do not
|
||||
replace the `T1-T5` roster; they freeze the product contract across the most
|
||||
important cross-layer seams.
|
||||
|
||||
Current tester automation status:
|
||||
|
||||
1. metadata-driven suite execution now exists for `Stage 0` and `Stage 1`
|
||||
2. one command can now build, deploy, run remote scenarios, and collect evidence
|
||||
3. the current `Stage 0` pipeline is operational but not yet passing end-to-end because the run still fails at the known first-write `dd_write` / `sync_all` barrier issue during `record-before`
|
||||
|
||||
Naming convention for this overlay:
|
||||
|
||||
1. `P20-Ax` = cross-task acceptance case
|
||||
2. each `P20-Ax` should map back to one or more `T1-T5` roster items
|
||||
3. each `P20-Ax` should eventually exist as tester evidence in `phase-20-test.md`, runner scenarios, or equivalent acceptance artifacts
|

### Acceptance Cases Required For Stronger Signoff
|
||||
|
||||
| ID | Acceptance contract | Developer proof anchor | Tester validation target | Current status |

|---|---|---|---|---|
|

| `P20-A1` | `WriteLBA != durability`; only `SyncCache()` / `sync_all` closes durability | `TestWriteLBAWithoutSyncCache_DoesNotAdvanceDurableBoundary`, `TestPublishHealthy_Gate4_RequiresDurability`, updated `blockvol` contract | rerun on real RF=2 path and prove plain write return is not treated as commit | developer-validated; tester pending |
|
||||
| `P20-A2` | fresh replica bounded catch-up closes as `freeze -> replay -> target reached -> live enable` | `TestBootstrap_SyncCacheIsDurabilityFence_NotWriteLBA`, `TestP16B_RunCatchUp_UpdatesCoreProjectionFromLiveRecovery` | rerun via `sw-test-runner suite weed/storage/blockvol/testrunner/suites/phase20-t6-stage0.yaml` with tester timeline capture and freeze the exact acceptance chain | developer-validated; tester pending |
|

| `P20-A3` | late attach cannot create LSN gap; retained WAL backlog ships before live tail | `TestBootstrap_LateAttach_ReplaysBacklogBeforeLiveTail`, `TestReplicaReadAfterShip` | rerun with delayed replica attach on real or runner path | developer-validated; tester pending |
|
||||
| `P20-A4` | catch-up timeout / retention loss fail closed into rebuild semantics | `TestExecuteCatchUpPlan_CallsbackOnFailureWithClassification`, `TestClassifyCatchUpFailure`, `NeedsRebuildObserved` closure subset | rerun with disturbance or retention-loss injection and freeze observed escalation | developer-validated; tester pending |
|
||||
| `P20-A5` | `publish_healthy` requires recovery + durability + accepted mode, not mere transport contact | `TestPublishHealthy_WholeChain_FreshRF2`, `TestBlockService_PrimaryPublicationChain_BootstrapPendingUntilBarrierThenHealthy`, server readiness/publication tests | rerun via `sw-test-runner suite weed/storage/blockvol/testrunner/suites/phase20-t6-stage0.yaml` and prove contact alone never produces healthy publication | developer-validated; tester pending |
|
||||
| `P20-A6` | stable identity is explicit and fail closed; missing `ServerID` must not degrade to address-derived identity | `TestP10P1_*`, `TestBlockService_ApplyAssignments_PrimaryMultiReplicaMissingServerID_SkipsOnlyInvalidReplica`, assignment conversion tests | rerun with malformed or missing identity inputs and freeze fail-closed behavior | developer-validated; tester pending |

Audience: engineers taking over `sw-block/engine/replication` and its integration in `weed/server`.
|
||||
|
||||
Goal: know **where truth lives**, **how to read the code in order**, and **where to add new rules** without breaking layering.

- **CoreEngine**: one **reducer** per volume — `Event` in → updated `VolumeState` + `Command` + `PublicationProjection`. No I/O.
|
||||
- **Sender / Session / Registry / RecoveryOrchestrator**: **per-replica recovery authority** — session phases, fencing, catch-up/rebuild execution, handshake from `RetainedHistory`.
|
||||
- **blockvol / server**: muscles **execute** commands and **report** facts; they must not silently fork “publication truth” outside events.

## 2. Repository map (what file does what)
|
||||
|
||||
| Area | Primary paths | Responsibility |
|
||||
|------|----------------|----------------|
|
||||
| Package entry & invariants | `sw-block/engine/replication/doc.go` | Read first — lists ownership/fencing rules. |
|
||||
| Core shell (Phase 14) | `engine.go`, `state.go`, `event.go`, `command.go`, `projection.go` | Volume-level mode, readiness, boundaries, emitted commands. |
|
||||
| Per-replica recovery | `sender.go`, `session.go`, `registry.go`, `budget.go`, `rebuild.go`, `outcome.go`, `history.go` | Session FSM, handshake classification, bounded catch-up. |
|
||||
| Orchestration | `orchestrator.go`, `driver.go`, `executor.go` | `ProcessAssignment`, `ExecuteRecovery`, stepwise recovery plans. |
|
||||
| Boundaries | `adapter.go` | `StorageAdapter` — engine never reaches into storage directly. |
|
||||
| Runtime helpers | `engine/replication/runtime/*.go` | Pending/step execution helpers — not the semantic core. |
|
||||
| Host integration | `weed/server/volume_server_block.go`, `block_recovery.go`, `block_protocol_state.go`, `weed/storage/blockvol/v2bridge` | Wires engine, applies observations, executes commands. |
|
||||
|
||||
---
|
||||
|
||||
## 3. Suggested first read order (~1–2 hours)
|
||||
|
||||
1. **`doc.go`** — invariant list (what must stay true).
|
||||
2. **`types.go`** — `SessionKind`, `SessionPhase`, `ReplicaState`, `Endpoint`.
|
||||
3. **`event.go` + `command.go`** — vocabulary of the core: what can be observed, what can be decided.
|
||||
4. **`state.go`** — `VolumeState`, `ReadinessView`, `BoundaryView`, `commandState` (idempotence keys).
|
||||
5. **`engine.go`** — `ApplyEvent`, `recompute`, `applyAssignment`, `primaryEligibleForPublish`, `bootstrapReason`.
|
||||
6. **`sender.go`** (execution APIs + `SessionSnapshot`) — how session fencing works.
|
||||
7. **`registry.go` + `orchestrator.go`** — how assignments become senders and recovery runs.
|
||||
8. **Host**: grep `ApplyEvent` / `v2Core` / `applyCoreEvent` in `weed/server` to see how events are produced.
|
||||
|
||||
---
|
||||
|
||||
## 4. Where to add a “new rule” (decision tree)
|
||||
|
||||
Ask: **what kind of rule is it?**
|
||||
|
||||
| Your change is about… | Put it in… | Typical pattern |
|
||||
|------------------------|------------|-----------------|
|
||||
| When the volume is `publish_healthy` / `bootstrap_pending`, or how readiness/boundary combine | **`CoreEngine`** — `recompute`, `primaryEligibleForPublish`, or new/extended `Event` handling | Add/adjust `Event`, update `ApplyEvent` branch, extend `recompute`; keep commands **pure** (no I/O). |
|
||||
| When a replica may receive live WAL tail, catch-up bounds, session invalidation | **`Sender` / `Session`** and/or **`RecoveryOrchestrator`** | Extend phase checks, `checkAuthority`, handshake/budget; **do not** duplicate mode logic in blockvol. |
|
||||
| Gating execution (e.g. live ship) from host-visible engine snapshots | **`weed/server`** (e.g. protocol execution sync) — **derive** from engine/registry, **set** policy on `BlockVol` | Keep engine free of TCP; host binds policy to data plane. |
|
||||
| Cluster-wide who is primary / epoch | **Master / assignment path** — not inside `CoreEngine` alone | VS consumes assignment as `AssignmentDelivered` (or equivalent adapter event). |
|
||||
|
||||
**Rule of thumb**: if the rule needs **only local observations** already modeled as `Event`, it belongs in **`engine.go`**. If it needs **per-replica session identity or LSN ranges**, it belongs in **`sender.go` / `session.go`**. If it needs **disk retention / pins**, use **`StorageAdapter`** and **`RecoveryDriver`** paths.
|
||||
|
||||
---
|
||||
|
||||
## 5. Checklist: adding a new **CoreEngine** `Event`
|
||||
|
||||
1. Define the type in **`event.go`** — implement `VolumeID() string`.
|
||||
2. Add handling in **`ApplyEvent`** in **`engine.go`** — update `VolumeState` fields only; no side effects.
|
||||
3. If the event implies work for the host, emit a **`Command`** (see **`command.go`**) or reuse an existing one.
|
||||
4. Call **`recompute(st)`** if you added fields that affect `Mode` / `Publication` (or rely on final `recompute` at end of `ApplyEvent` — today every path ends with `recompute`).
|
||||
5. Extend **`VolumeState.Snapshot()`** in **`state.go`** if you added new copyable state.
|
||||
6. Add/extend **tests**: `phase14_*_test.go` or focused tests in `engine` package.
|
||||
7. **Wire the host**: wherever the observation is detected in `weed/server`, enqueue **`CoreEngine.ApplyEvent`** (or the project’s adapter) so the event stream is **complete**.
|
||||
|
||||
---
|
||||
|
||||
## 6. Checklist: changing **Mode** or **Publication** semantics
|
||||
|
||||
- Read **`recompute`** and **`bootstrapReason`** end-to-end — they are the **single place** for outward mode naming on the bounded path.
|
||||
- If you add a new `ModeName`, add it in **`state.go`** and handle it in **`recompute`** (and any projection consumers).
|
||||
- **Do not** infer publish health only from shipper logs in random packages — align with **`primaryEligibleForPublish`** or deliberately extend it with new `Event`s (e.g. new boundary).
|
||||
|
||||
---
|
||||
|
||||
## 7. Integration: `weed/server` expectations
|
||||
|
||||
- **Assignments** from master should eventually surface as **`AssignmentDelivered`** (or the unified adapter equivalent) with correct **epoch** and **replica IDs**.
|
||||
- **Observations** (receiver ready, shipper configured/connected, barrier OK/fail, LSN advances) must be **turned into events**; missing events ⇒ core state diverges from reality.
|
||||
- **Commands** returned by `ApplyEvent` must be **executed or explicitly dropped** by policy — silent ignore leads to stuck `bootstrap_pending`.
|
||||
|
||||
Grep starting points: `v2Core`, `ApplyEvent`, `applyCoreEvent`, `coreProj`.
|
||||
|
||||
---
|
||||
|
||||
## 8. Testing strategy (short)
|
||||
|
||||
| Layer | What to prove |
|
||||
|-------|----------------|
|
||||
| `engine` package tests | Deterministic transitions: given event list ⇒ final `VolumeState` / projection. |
|
||||
| Sender/session tests | Session ID fencing, phase transitions, budget escalation. |
|
||||
| `weed/server` tests | Host wiring: policy + observations ⇒ expected gating or readiness. |
|
||||
|
||||
See `v2-proof-and-retest-pyramid.md`.
|
||||
|
||||
---
|
||||
|
||||
## 9. Common pitfalls
|
||||
|
||||
- **Duplicating “truth”** — updating readiness or durable LSN only in ad-hoc variables without emitting **`Event`**.
|
||||
- **Treating `WriteLBA` success as commit** — core **`publish_healthy`** requires **`DurableLSN > 0`** for primary path via **`primaryEligibleForPublish`**; align client docs with barrier/group commit semantics.
|
||||
- **Mixing Core and Sender rules** — mode in `CoreEngine`, per-replica execution in `Sender`; avoid cross-importing the wrong way from `blockvol`.
|
||||
- **Breaking idempotence** — `commandState` tracks what was already commanded; new commands need stable keys (epoch + replica + target LSN where applicable).
