Architecture Review Fix Plans — Master Tracker

Created: 2026-07-08 Source: archreview/00-OVERALL.md and domain reports 01–08 Plans: 8 implementation plans, 192 tasks (191 net of one cross-plan duplicate — see Dedupe Rulings)

Every plan follows the TDD bite-sized-task format and ships a co-located .tasks.json manifest. Execute a plan with the superpowers-extended-cc:executing-plans skill (pass the plan path); it reads/updates the .tasks.json. When a plan's status changes, update the table below — this file is the single source of truth for initiative progress.

ROUND 2 (2026-07-12)

Source: the round-2 re-review (all 8 archreview/0X-*.md reports rewritten 2026-07-12 at HEAD 8c888f13): every round-1 finding source-verified (168 fixed, 0 regressions, 0 false claims), plus 56 new findings (1 Critical / 4 High / 15 Medium / 36 Low) concentrated in post-baseline code. Round-2 plans: 8 plans, 86 tasks.

Round-2 progress: 0 of 86 tasks.

Round-2 P0 (do first, any order)

1. R2-08 T1/T2 — rotate the exposed wonder-app-vd03 API key; delete test.txt + the three root credential files (ALL contain live secrets incl. a production sysadmin password). needs-user.
2. R2-02 T1–T4 — the Critical: unify the active-node predicate; failing-first buffer-wipe repro then fix.
3. R2-02 T5–T7 — the resync frame-size High (chunked protocol).
4. R2-04 T2–T4 — bound the rollup backfill before the next central failover at data volume.

Round-2 Cross-Plan Mutexes & Dedupe Rulings

Surface / finding	Ruling
SiteAlarmLiveCacheService.cs	R2-02 T10 (coalescing) and R2-07 T10 (aggregator deathwatch/sticky IsLive) must NOT run concurrently — serialize, either order. R2-02 T12/T15 also touch adjacent files; keep the whole live-alarm slice single-lane across plans.
ManagementActor.cs	Single-writer lane (round-1 rule stands): R2-07 T4/T6 and R2-02 T13 (HandleDeleteSite) serialize against each other.
IScriptArtifactChangeBus	Publisher Add-fix = R2-05 T5; subscriber wiring + Host comment = R2-06 T1/T2. Independent, no cross-plan blockedBy.
Failover envelope measurement (report-08 NF2)	Owned by R2-01 T4; R2-08 T10 only repoints the register row.
Deferral-register consolidation (reports 01 N6 / 08 NF5)	Owned by R2-08 T10/T11.
Options-validation tail	Split by owner: SiteRuntime knobs = R2-03 T4; Transport knob = R2-05 T8; S&F sweep knobs = R2-02 T9; AuditLog/Host = R2-08 T5–T8.
SBR keep-oldest active-crash topology gap	Still a registered deferred USER decision — no round-2 plan fixes it; R2-01 documents/measures it, R2-08 T10 moves it into the canonical register.

Round-2 Recommended Waves

• Wave 0 (P0): R2-08 T1–T3 (needs-user) ∥ R2-02 T1–T7 ∥ R2-04 T1–T4.
• Wave 1: rest of R2-02 ∥ R2-03 ∥ R2-05 ∥ R2-06 (all file-disjoint domains); R2-01 T1–T4 (drill + measurement, needs live docker cluster).
• Wave 2: R2-07 (after R2-02's live-alarm slice lands, honoring the mutex) ∥ rest of R2-04 ∥ rest of R2-01 ∥ rest of R2-08.
• Full-suite sweep + docker redeploy at the end, per round-1 practice (watch for stale enum-count lock-in tests — bit PLAN-04 and PLAN-07).

Progress: P0 (Wave 0) complete — 10 of 192 tasks done (2026-07-08): PLAN-01 T1/T3/T4, PLAN-02 T1/T2, PLAN-05 T1, PLAN-07 T1/T2/T3, PLAN-08 T1. Merged to main (3f8e18c6). One follow-up surfaced during execution — see the active-node-crash SBR gap in the deferred registry.

Wave 1 — PLAN-02 COMPLETE (2026-07-08): all 24 tasks delivered and merged to main (ce239f6f). Store-and-Forward: active-node delivery gate (Func<bool> seam), bounded/short-circuiting retry sweep, upsert-based standby applies + anti-entropy peer resync, WAL+busy_timeout, epoch-ms due-check, ordered single-reader audit-observer channel; Notify.Send enqueue-only (deferToSweep, maxRetries:0, corrupt-payload parks not discards); gRPC channel keying + DropOldest debug-stream eviction counting + 5s application heartbeat; oldest-parked-age health field. Docker cluster rebuilt on merged image (Healthy, 5 singletons, corrected active-node semantics) and 3 sites seeded. Initiative total: 52 of 192 (sum of the Done column above).

Wave 1 — PLAN-01 COMPLETE (2026-07-08): all 23 tasks delivered on worktree branch worktree-archreview-wave1-plan01 (merged to main ec47cb56 2026-07-09; branch since removed). Beyond the P0/early-Wave-1 spine (SBR downing + two-node rig T1/T3/T4; oldest-member active-node unification via ClusterActivityEvaluator T5–T8; CentralSingletonRegistrar drains T2/T9/T10; health-report acking T11–T12), Wave 1 also landed: metrics-staleness + status-transition state machine and its dashboard surface (T13/T14), deleted-site eviction from the aggregator (T18), seed-vs-metrics-port validator + AllowSingleNodeCluster + docker stop_grace_period (T15–T17), rate-limited dead-letter warnings (T19), the down-if-alone process-exit recovery loop (T20), the failover-drill.sh SIGKILL drill (T21), and the REQ-HOST-6 + Traefik/Host doc reconciliation with unused-Akka.Hosting-package removal (T22/T23). PLAN-01 now 23 / 23. Initiative total: 30 of 192. Each task TDD + pathspec-committed; full solution builds clean (0 warnings). Three deploy-artifact sub-edits (deploy/wonder-app-vd03/ appsettings + install.ps1, Tasks 16/20/23) were deferred on a mistaken not-in-repo rationale; corrected and applied on-disk by PLAN-R2-01 (2026-07-12) — see the Deferred-during-Wave-1 entry.

Wave 1 — PLAN-03 COMPLETE (2026-07-09): all 26 tasks delivered and merged to main (c7a0c922). Site Runtime & DCL hardening across nine TDD batches: reconnect/backoff leak fixes and the DeployCompileValidator compile gate, DCL adapter lifecycle + alarm-filter overwrite warning (S10) + observed adapter dispose on stop (S9), site-node cert reconcile (CertStoreActor trusted-store export → DeploymentManagerActor MemberUp-driven additive push), replicated config-fetch retry (ConfigFetchRetryCount), invariant-culture conditional-trigger fallback (C6), bounded/DropOldest event-channel comment fix (C2), and the SiteRuntime/DCL requirements-doc sync. Three low-severity items deferred with rationale (see PLAN-03 coverage table). Full CentralUI/SiteRuntime/DCL suites green. Initiative total: 78 of 192 (sum of the Done column above). Two out-of-band fixes also landed post-merge: PLAN-07's SecuredWrites IBrowseService bUnit-harness gap (resolved 2026-07-09, 9049690b) — a pre-existing failure surfaced during PLAN-03's full-suite run, not a plan task.

Wave 2 — PLAN-04 COMPLETE (2026-07-09): all 26 tasks delivered on worktree branch worktree-archreview-wave2-plan04 (Batches 1–3 fast-forwarded to main+origin; Batches 4–8 + T24 + the T26 fix still on the branch, pending finishing-a-development-branch). Site SQLite retention chain + partition-switch hardening + purger role-grants/index migrations (T1–T9), backlog KPI + SiteCalls freshness upsert + EF EnableRetryOnFailure (T10–T12), operator-identity audit on Retry/Discard relays + reconciliation composite-keyset cursor/abandoned-row audit/NodeB failover (T13–T18), time-sliced KpiSample purge + single-query NotificationOutbox KPI + SiteCalls OPTION (RECOMPILE) (T19–T21), short-first-tick purge timers + data-layer cleanups + bounded parallel notification delivery (T22, T23, T25), the design-doc reconciliation pass (T24). T26 (final dotnet build/dotnet test sweep): build 0 warn/0 err; all 30 unit + integration test assemblies green after fixing one stale enum-count lock-in test (22d52390 — Task 17 added AuditKind.ReconciliationAbandoned but left AuditEnumTests asserting 14 members; the per-task filtered runs never hit that Commons guard, so the full sweep caught it). The Playwright E2E residue (8–9 fails) is environmental — a 17h-old docker cluster whose site containers fail instance deploy with SQLite Error 14: unable to open database file; the failure set is non-deterministic and PLAN-04 changed zero files in that project or the deployment-DB path. Initiative total: 104 of 192 (sum of the Done column).

Wave 3 — PLAN-05 COMPLETE (2026-07-10): all 25 tasks delivered on worktree branch worktree-archreview-wave3-plan05 and merged to main ec23db35 via fast-forward (main was still at PLAN-04's dbd3ed2f, zero divergence; worktree removed, branch deleted). Templates/Deployment/Transport hardening across seven report-and-wait waves: import correctness spine (BundleImporter consumes BaseTemplateName/composition/inheritance edges + import-time acyclicity, MinTimeBetweenRuns/ExecutionTimeoutSeconds/LockedInDerived/native-alarm-sources/real AreaName carried through — T1–T7), a reflection round-trip equivalence guard that surfaced and fixed 5 silent-data-loss holes (ES retry+methods-on-Add, notification recipients, folder parent edges — T8), flattener/collision-detector repeated-composition fixes (T9/T10), revision-hash + DiffService native-source coverage (T11/T12), native-source lock enforcement (T13), the IScriptArtifactChangeBus invalidation contract + Host in-process bus + Transport post-commit publisher (T14, plan-06 handoff), compile-verdict cache + read-only-path compile skip + post-success audit isolation + central NotDeployed-delete (T15–T18), and the closing security/quality chain: import blocker severity split (template-script findings advisory, ApiMethod hard — T19), the script trust gate on bundle import (5th ScriptTrustValidator call site, over script bodies and Expression-trigger bodies — T20, given a code-reviewer security pass that caught + fixed 2 Important gaps: expression-trigger coverage and per-origin local-declaration scoping), ScriptTrustPolicy deny-list hardening (T21), LineDiffer input cap (T22), ArtifactDiff placeholder-identity resolution (T23), the low-severity batch (session cap / full error lists / leaf-fallback warning — T24), and the design-doc + CLAUDE.md sweep (T25). Terminal verification: full slnx build 0 warn/0 err; the entire dotnet test sweep green (~5,900 unit + integration tests across every suite) plus a direct CLI.Tests run (341). Only residue: the same environmental 8 CentralUI.PlaywrightTests Deployment E2E failures (SQLite Error 14 on instance deploy — needs a live docker cluster; PLAN-05 touched zero files in that project's deployment-DB path). Initiative total: 128 of 192 (sum of the Done column).

Wave 4 — PLAN-06 COMPLETE (2026-07-10): all 24 tasks delivered and merged to main 3e964ac2 via fast-forward (main was still at PLAN-05's 9b0cf44c, zero divergence; worktree removed, branch deleted). Edge Integrations hardening across six report-and-wait waves of file-disjoint parallel subagents: the InboundAPI spine — revision-checked compiled-handler cache (heals failover / direct-SQL / known-bad staleness, DB row now authoritative — T1/T2), InvalidateMethod seam (T3; the bus subscriber was NOT wired here — arch-review 06 round-2 N1 — and shipped later via PLAN-R2-06 T1), deferred DI-scope disposal + orphan-execution telemetry (T4), machine-readable error codes incl. SITE_UNREACHABLE + 415-on-non-JSON (T5), IOptionsMonitor hot-reload (T6), parallel startup compile (T7); the ESG per-system TimeoutSeconds full vertical slice (entity→EF migration→artifact→site SQLite→client honor→mgmt→CLI→UI→doc — T8–T12) plus {param} path-template substitution (T13), bounded outbound response buffering (T14), structured JSON AuthConfiguration with legacy-colon fallback (T15), cancellation-aware IsTransient (T16); the Notification batch — SMS first-transient short-circuit (T17), wired the dead SmsConfiguration.MaxRetries/RetryDelay per-type retry policy (T18), configurable OAuth2 authority/scope (entity→EF migration→token service→mgmt/CLI/UI surfaces — T19/T20), deterministic lowest-Id SMTP selection + atomic OAuth2 token cache (T21), Twilio AccountSid format validation (T22); and the docs (DelmiaNotifier at-least-once semantics — T23; dual-key API-key rotation procedure — T24). Two EF migrations added (AddExternalSystemTimeoutSeconds T8, AddSmtpOAuth2AuthorityScope T19, serialized on the shared snapshot). Terminal verification: full slnx build 0 warn/0 err; every unit + integration suite green (InboundAPI 253, ESG 132, NotificationOutbox 132, NotificationService 57, ManagementService 245, CLI 346, CentralUI 893, SiteRuntime 494, Commons 597, ConfigDB 338, Host 260, + all others). Only residue: the same environmental 8 CentralUI.PlaywrightTests Deployment E2E failures (SQLite Error 14 on instance deploy — needs a live docker cluster; PLAN-06 touched zero files in that project's deployment-DB path). Execution note: isolation:"worktree" subagents proved non-isolating here (shared index → commit races); the working model was pre-created dedicated git worktrees per task + cherry-pick onto an integration branch + per-wave combined build/impacted-suite barrier. Initiative total: 152 of 192 (sum of the Done column).

Wave 5 — PLAN-07 COMPLETE (2026-07-10): all 32 active tasks (T4–T32; T1–T3 landed in P0; T33 skipped-duplicate — CLI.Tests already in the slnx via PLAN-08 T1) delivered on worktree branch plan07 and merged to main via fast-forward (main was still at PLAN-06's 4fb754f9, zero divergence; all worktrees removed, branch deleted). UI/Management/Security hardening across six report-and-wait waves of file-disjoint parallel subagents against the dominant ManagementActor single-writer lane (15 tasks serialized in one integration worktree; the file-disjoint remainder ran in dedicated per-task worktrees, cherry-picked in with a per-wave combined build + impacted-suite barrier): C1 auth-disabled artifact killed + DisableLoginGuard fail-fast (T1–T3, P0); C2 DeployToSiteAsync single-site deploy + fleet-wide site-scope guard (T4/T5); C3 connection/external-system/DB-connection secret elision via ConfigSecretScrubber + sentinel-preserving update (T6–T9); UA1/C6/C5 any-of role gates + ListSecuredWrites gating + area-gate reconciliation (Designer|Deployer) + role-casing canonicalization (T10–T12); UA2 the frozen GetRequiredRoles authorization matrix over all 138 registered commands + dispatch-coverage guard (T13/T24); S2/P3 real server-side secured-write TTL + expiry-at-approve/reject + opportunistic list sweep + list paging + UI history pager & submission-age dialog (T14–T18); S1 5-min transport/deploy Ask timeout + shipped config (T19/T20); C4 additive SiteIdentifier on browse/verify/cert commands + actor dispatch (Designer browse/verify, Admin cert-trust) + dispatch-coverage + CLI parity (T21–T25); P1/UA5 LoginThrottle per-username+IP LDAP-bind lockout wired into every bind surface (T26/T27); P2 additive Skip/Take paging on template/instance lists (T28); S3 PollGate reentrancy guard on Health/AlarmSummary timers (T29); S4 transport single-flight + export base64-copy elimination (T30); S5/C7/C8/P4/UA6 debug-stream fault logging + event-log-filter doc fix + AlarmSummary memoization/a11y + the stale CLAUDE.md SourceNode note corrected (C7/C8 both verified true — T31/T32). Two message-contract additions (AuditKind.SecuredWriteExpire, secured-write list paging params) landed additively; no EF migrations needed. Terminal verification: full slnx build 0 warn/0 err; 28 of 30 test assemblies green (ManagementService 448 incl. the frozen matrix + dispatch-coverage, CentralUI 898, CLI 359, Security 175, Commons 609, Communication 263, Transport 138, ConfigDB 341, SiteRuntime 494, Host 260, + all others), after fixing one stale enum-count lock-in test (AuditEnumTests 15→16 for T15's additive SecuredWriteExpire — the per-task filtered runs never hit that Commons guard, so the full sweep caught it, exactly as in PLAN-04). Only residue: the same environmental 8 CentralUI.PlaywrightTests Deployment E2E failures (SQLite Error 14 on instance deploy — needs a live docker cluster; PLAN-07 touched zero files in that project's deployment-DB path). Initiative total: 181 of 192 (sum of the Done column; PLAN-07's max is 32/33 with T33 a documented skip).

Wave 6 — PLAN-08 COMPLETE (2026-07-10): INITIATIVE COMPLETE. All 10 remaining tasks (T2–T11; T1 landed in P0) delivered on integration branch plan08 and merged to main via fast-forward (main was still at PLAN-07's 187fbd7c, zero divergence; all worktrees removed, branches deleted). Conventions/tests/underdeveloped-areas hardening across two report-and-wait waves of file-disjoint parallel subagents — the initiative's single highest-parallelism slice (8 concurrent implementers in Wave 1): §1.5 eager options validation — new OptionsValidatorBase<T> validators wired via .ValidateOnStart() + TryAddEnumerable across 12 components in four tasks: Communication + DataConnectionLayer (T2, + 3 extra TimeSpan fields beyond the plan; string-only global-options classes correctly skipped), the site pipeline SiteRuntime/StoreAndForward/SiteEventLog bound in Host (T3), edge/management InboundAPI/ESG/Notification/ManagementService (T4, correctly leaving SecuredWritePendingTtl≤0 and empty ApiKeyPepper valid as legitimate disable/dev defaults), central Transport/SiteCallAudit/DeploymentManager (T5, incl. the security-sensitive Pbkdf2Iterations >= 100_000 floor; validating base not Resolved* properties); §1.3/#23 excised the vestigial site-side notification-list surface — deleted SiteNotificationRepository, its DI registration, and the dead StoreNotificationListAsync/StoreSmtpConfigurationAsync write paths, keeping PurgeCentralOnlyNotificationConfigAsync as the security cleanup (T6, with a Site_NotificationRepository_IsNotRegistered design-invariant lock replacing the old registration test); §2.3 the first real perf-envelope test — site-wide stream throughput (100k events, ≥10k/s + ≥90% delivery assertions — T7) plus a skipped failover-timing harness documenting the 25s-envelope protocol pending PLAN-01's two-node rig (T8); §1.8 contract-lock tests for the 7 highest-traffic ClusterClient records enforcing additive-only evolution under version skew (T9, which surfaced a real wire-behavior finding: Newtonsoft ignores C# ctor optional-param defaults, so a missing trailing field deserializes to default(T) not the C# default — the test now locks that reality); §1.1/§1.3/§1.4/§4 the docs-drift batch — Commons Observability/ folder, the site-repo NotSupportedException exception, the ..\→../ csproj-separator fix, the scoped "24 of 27 reference docs" README claim, and the DelmiaNotifier convention-exception bullet in CLAUDE.md (T10); and §3 the deferred-work register triaging the 23-item inventory into fix-now (plan-owned) vs deferred-with-rationale+revisit-trigger (T11). No EF migrations, no wire-contract changes, no new runtime components — all convention-hardening around existing seams. Terminal verification: full slnx build 0 warn/0 err; the entire dotnet test sweep green across all 30 test assemblies — now including CLI.Tests (359) at the solution level for the first time (T1's slnx addition) — except two documented non-PLAN-08 residues: (1) a pre-existing Communication.Tests gRPC observable-gauge timing flake (SiteStreamGrpcServerTests.SiteConnectionUpGauge_*, proven to flake 3/6 on base main 187fbd7c; PLAN-08 touched zero Grpc/ files), and (2) the same environmental 8–9 CentralUI.PlaywrightTests Deployment E2E failures (SQLite Error 14 on instance deploy — needs a live docker cluster). Initiative total: 191 of 192 (sum of the Done column) — the single remaining gap is PLAN-07 T33, a documented skipped-duplicate (CLI.Tests slnx addition, delivered instead by PLAN-08 T1). All 8 archreview plans complete.

Parallelization Map — Incomplete Tasks (2026-07-09)

Covers the plans with open tasks: none — all 8 plans complete as of 2026-07-10 (Wave 6, PLAN-08). PLAN-01/02/03/04/05/06/07/08 are complete; the section below is retained for its cross-plan mutex analysis and the record of how PLAN-07's ManagementActor lane and PLAN-08's highest-parallelism validator slice were run. "Ready" = every blockedBy entry is already completed in the plan's .tasks.json, so the task can start now. Ready sets are recomputed below from the live manifests; re-derive after each merge.

Cross-plan serialization mutexes (a task holding one must be the ONLY task touching that surface, anywhere)

Shared surface	Tasks that touch it (P0n = PLAN-0n)	Rule
ManagementService/ManagementActor.cs	P05 T13; P06 T2, T3, T11, T20, T22; P07 T5, T7, T8, T9, T10, T11, T12, T15, T16, T17, T22, T23, T28, T30, T31	Global single-writer. At most one ManagementActor task in flight across ALL plans. PLAN-07 already serializes its 15 internally — extend the same mutex to P05 T13 and the five P06 tasks.
EF migration model-snapshot (ConfigurationDatabase/Migrations/* + *ModelSnapshot)	P06 T8 (ready), T19	Never two migration tasks concurrently. Build first, never --no-build (empty-scaffold gotcha). Only P06 T8 is ready now.
Host/Program.cs	P06 T7; P08 T4	Single-writer — don't run P06 T7 and P08 T4 at the same time.
DeploymentManager/ArtifactDeploymentService.cs	P06 T10; P07 T4	Single-writer (P06 T10 not yet ready; P07 T4 is).
SiteRuntime/Persistence/SiteStorageService.cs	P06 T10; P08 T6	Single-writer (neither ready yet).
NotificationOutbox/NotificationOutboxActor.cs	P06 T18, T21	Intra-PLAN-06 (PLAN-04's delivery work is done and no longer touches it).
CentralUI/.../Monitoring/AlarmSummary.razor	P07 T29, T32	Intra-PLAN-07 — serialize.
Docs (low-risk, coordinate — pathspec-commit + last-writer reconcile): CLAUDE.md (P05 T25, P06 T18, P07 T15/T31/T33, P08 T10), Component-ManagementService.md, Component-InboundAPI.md, Component-ExternalSystemGateway.md, Component-NotificationService.md	multiple	Not a hard blocker; do not co-edit the same file in the same wall-clock window.

Dedupe reminder: P07 T33 is a skip — CLI.Tests is already in the slnx via P08 T1 (done). Mark it skipped-duplicate in PLAN-07-…tasks.json; do not execute it.

Ready set + concurrent lanes per plan

• PLAN-04 — ✅ COMPLETE (2026-07-09); all 26 tasks done, merged to main dbd3ed2f. No longer a parallelization lane.
• PLAN-05 — ✅ COMPLETE (2026-07-10); all 25 tasks done, merged to main ec23db35 (fast-forward). No longer a parallelization lane. (Historical: the BundleImporter serial chain T1→2→…→6→19→20→23 ran in-worktree; T14's IScriptArtifactChangeBus contract is shipped for PLAN-06 to consume.)
• PLAN-06 — ✅ COMPLETE (2026-07-10); all 24 tasks done, merged to main 3e964ac2 (fast-forward). No longer a parallelization lane. (Historical: ran as 6 waves — W1{1,6,7,8,17,23} W2{2,9,10,12,18,19} W3{3,13,21} W4{4,11,14} W5{5,15,20} W6{16,22,24}; the ExternalSystemClient chain T9→13→14→15→16 and inbound-executor chain T1→3→4→5 were the two serial spines.)
• PLAN-07 — ✅ COMPLETE (2026-07-10); all 32 active tasks done, merged to main (fast-forward); T33 skipped-duplicate. No longer a parallelization lane. (Historical: ran as 6 waves — W1{4,6,10,14,19,21,26,29} W2{7,8,9,27,32} W3{11,20,22,23} W4{13,15,16,17,24} W5{5,12,18,25,28} W6{30,31}; Lane M = the ManagementActor single-writer chain T10→7→8→9→11→22→23→15→16→17→5→12→28→30→31 driven serially in the integration worktree, with the file-disjoint remainder in dedicated per-task worktrees cherry-picked in per wave.)
• PLAN-08 — ready: {2, 3, 4, 5, 7, 8, 9, 11} — each is a new per-component validator file or an isolated test/doc, so mutually parallel, with one caveat: T4 shares Host/Program.cs with P06 T7 (sequence them). This is the initiative's single highest-parallelism slice (independent validator files). T6, T10 stay blocked.

Recommended concurrent execution

Run up to five plan-lane executor sessions concurrently (one each for PLAN-04/05/06/07/08 — PLAN-01/02/03 are done), with these coordination rules layered on top:

1. One ManagementActor task at a time, initiative-wide — route P05 T13 and every ready P07 ManagementActor task ({8,9,10,12,28,30,31}) through a single serialized "Lane M"; start with P07 T10.
2. One migration at a time — only P06 T8 is a ready migration; hold the snapshot until it lands.
3. Host/Program.cs mutex — P06 T7 ⟂ P08 T4.
4. Inside each session, dispatch that plan's ready, file-disjoint tasks as concurrent implementers per the lanes above; use pathspec-scoped commits and verify each landed on HEAD (known repo failure mode — see Execution hygiene).
5. Highest-value immediate fan-out: PLAN-08 T2/T3/T5/T7/T8/T9/T11 (independent validator + test + doc files) and PLAN-07's non-ManagementActor octet can run as many concurrent implementers today; the throughput ceiling is Lane M (ManagementActor) and the single migration lane.

P0 — Do These First (regardless of plan order)

✅ All six delivered 2026-07-08 on branch archreview-p0 (worktree). TDD throughout; full solution builds clean; touched suites green (Host, Communication 244, Security 163, Transport 127+63, IntegrationTests cluster rig). One finding surfaced — see the active-node-crash SBR gap in the deferred registry below.

1. ✅ PLAN-01 Task 1 — enable the SBR downing provider (the system-wide Critical; one line + parsed-config test). Provider verified active via the live two-node rig.
2. ✅ PLAN-01 Tasks 3–4 — the two-node kill-test rig (TwoNodeClusterFixture); integration-proves Task 1 and later PLAN-02 work. Task 4 rewritten to the achievable keep-oldest guarantee (younger-crash → SBR downs it → oldest keeps singleton); oldest-crash gap registered as follow-up.
3. ✅ PLAN-07 Tasks 1–3 — DisableLoginGuard + scrub deploy/wonder-app-vd03 (Critical; unauthenticated prod surface). Guard + Host wiring committed; deploy/ is gitignored so its scrub is on-disk-only (not version-controlled), effective on next redeploy.
4. ✅ PLAN-02 Tasks 1–2 — ClusterClient generation-suffixed names (Critical crash-loop dropping routing to all sites).
5. ✅ PLAN-05 Task 1 — bundle import consumes BaseTemplateName (Critical silent data loss).
6. ✅ PLAN-08 Task 1 — CLI.Tests into the slnx (protects every subsequent plan's test runs). 341 CLI tests now run at the solution level.

Cross-Plan Dependency Map

Hard-ish sequencing (execute earlier):

• PLAN-01 Tasks 5–7 → PLAN-02 Tasks 3–4. PLAN-02's standby S&F delivery gate is a Func<bool> seam with marked swap points; it works standalone but its final wiring consumes PLAN-01's ClusterActivityEvaluator / SelfIsPrimary (singleton-host semantics).
• PLAN-01 Tasks 3–4 → PLAN-02 integration proof. The two-node rig is how PLAN-02's Critical fixes get integration-verified.
• PLAN-04 Task 13 (additive RequestedBy message change) before any PLAN-07 sender refactors touching the same messages.

Soft seams (either order works, coordinate):

• PLAN-05 Task 14 (IScriptArtifactChangeBus) ↔ PLAN-06 Task 3 (InboundScriptExecutor.InvalidateMethod). PLAN-06 Task 1's per-request revision check is the designed correctness fallback, so there is no hard sequencing; when both land, wire the bus to the invalidate seam. Closed 2026-07-13 (PLAN-R2-06 T1): ScriptArtifactChangeSubscriber (InboundAPI hosted service) subscribes and invalidates on ApiMethod notifications.
• PLAN-03's DeployCompileValidator should adopt PLAN-05's compile-cache abstraction once it exists (later refactor, not a blocker).
• PLAN-03 Task 8's stuck-thread watchdog pattern is reusable by PLAN-06 Task 4 (inbound orphan counter).

EF Core migrations — serialize globally. Migration-adding tasks exist in PLAN-04 (Tasks 6, 8), PLAN-06 (Tasks 8, 19), and possibly PLAN-07 (secured-write expiry). All share one model snapshot: never run two migration tasks concurrently, and always build first (never --no-build on dotnet ef migrations add — known empty-scaffold gotcha).

Shared-file merge surfaces (don't run these plans' overlapping tasks concurrently):

File / area	Plans touching it
ManagementActor.cs	PLAN-07 (15 tasks, serialized within plan), PLAN-05 (management-path publish), PLAN-06 (method-update paths)
deploy/wonder-app-vd03/appsettings.Central.json	PLAN-07 (auth), PLAN-01 (Cluster/Node sections)
NotificationOutboxActor.cs	PLAN-04, PLAN-06 (SMS retry policy)
StoreAndForwardService.cs / site tracking store	PLAN-02 (primary owner), PLAN-04 Task 15 (keyset query)
Host/Program.cs + service registration	PLAN-01, PLAN-08 (options validation)
SiteHealthReport (Commons record, additive fields)	PLAN-03 Task 6, PLAN-04 health-event fields
Transport BundleImporter.cs	PLAN-05 (primary, serialized chain), PLAN-07 (import idempotency note)

Dedupe Rulings (one owner per finding)

Finding	Owner	Others must skip
CLI.Tests into slnx	PLAN-08 Task 1 (also retires CLAUDE.md gotcha + memory note)	PLAN-07 Task 33 — skip as duplicate; mark skipped-duplicate in its tasks.json
DisableLogin: true artifact	PLAN-07 Tasks 1–3	PLAN-01 references only
AuditLog reconciliation NodeB failover	PLAN-04 Task 18	PLAN-08 pointer only
SmsConfiguration.MaxRetryCount unused	PLAN-06 Task 18	PLAN-08 pointer only
Transport AreaName: null	PLAN-05 Task 7	PLAN-08 pointer only
Role-casing normalization	PLAN-07 Task 10 chain	PLAN-08 pointer only
Two-node failover rig	PLAN-01 Tasks 3–4	PLAN-08 Task 8 is a documented placeholder; PLAN-02 consumes
Script-artifact invalidation contract	PLAN-05 Task 14 (design + publisher)	PLAN-06 implements the inbound consumer

Recommended Execution Waves

• Wave 0 (P0 list above). Independent files; all six items can run in parallel. ~1 focused session.
• Wave 1 — stability spine. Rest of PLAN-01 (active-node semantics, drains); PLAN-02 Tasks 3–9 (standby gate, gRPC channel keying, sweep bounding); PLAN-03 Tasks 1–4 (reconnect leak, compile gate); PLAN-04 Tasks 1–5 (purge chains); PLAN-05 import chain Tasks 2–6; PLAN-06 Tasks 1–4 + 8; PLAN-07 Tasks 4–9 (deploy scoping, secret elision).
• Wave 2 — remainder. All other tasks per intra-plan blockedBy edges; migration tasks serialized globally; docs-update tasks land with their code tasks (repo rule: doc + code + tests together).
• Wave 3 — closeout. PLAN-08 Task 11 (deferred-work register), each plan's doc-sweep task, then a full dotnet build ZB.MOM.WW.ScadaBridge.slnx + dotnet test (which now includes CLI.Tests) + bash docker/deploy.sh + the two-node drill from PLAN-01.

Execution hygiene: work in a dedicated worktree (not the primary checkout); one plan per executor session where possible; for parallel implementers use pathspec-scoped commits and verify every commit landed on HEAD afterward (both are known failure modes in this repo's history). Re-verify a finding's line numbers before editing — reports and plans cite the code as of 2026-07-08.

Deferred / Won't-Fix Registry (initiative-level)

Consolidated in PLAN-08 Task 11 → docs/plans/2026-07-08-deferred-work-register.md (triages the 23-item inventory from report 08 plus each plan's coverage-table deferrals: serializer swap, hash-chain/Parquet, aggregated live alarm stream, central cert-trust persistence, runtime script sandbox, clustered-GUID benchmark, TLS profile, Dockerfile HEALTHCHECK, etc.). Nothing from the review is silently dropped: every report finding is either a task, an ownership pointer, or a registered deferral with rationale.

Follow-up discovered during P0 execution (2026-07-08)

• Active(oldest)-node hard crash is NOT covered by two-node keep-oldest — total central outage until restart. PLAN-01 Task 1's downing-provider-class fix is verified active (a hard-crashed node now transitions Unreachable → Down → Removed, impossible under the pre-fix NoDowning default). But while building PLAN-01 Task 4's behavioral proof, the live two-node rig showed (Akka 1.5.62) that keep-oldest downs the partition without the oldest: crashing the younger node is survivable (oldest keeps its singletons), but crashing the oldest node makes the younger survivor down itself (Down ~8s, terminated ~10s) → the whole central cluster is lost until the crashed node restarts. down-if-alone = on does not help on a hard crash (the alone-oldest is dead and cannot down itself). Because ScadaBridge treats oldest = active node (PLAN-01 Task 5 ClusterActivityEvaluator), this means a crash of the active central node does not fail over to the standby — the scenario operators care most about. Task 4's test was rewritten to prove the achievable guarantee (younger-crash → SBR downs it → oldest keeps singleton) and documents this asymmetry in its XML doc. Remedy is a topology/strategy decision (deferred, owner: user): e.g. keep-majority + a 3rd/lighthouse seed node, static-quorum, or an explicit accepted-risk note. Not fixed in P0 to avoid silently changing the production SBR strategy.

Deferred during Wave 1 PLAN-01 execution (2026-07-08)

• deploy/wonder-app-vd03/ overlay edits — applied on-disk 2026-07-12 by PLAN-R2-01 Tasks 5-6 (the earlier not-in-repo deferral rationale was factually wrong). PLAN-01 Tasks 16, 20, and 23 each specified a small edit to the on-host deployment overlay (appsettings.Central.json/appsettings.Site.json: add AllowSingleNodeCluster: true + drop the phantom seed, add NodeName central-a/node-a; install.ps1: complete the recovery actions with sc.exe failureflag for the down-if-alone restart contract). The original deferral claimed the artifact directory "is not present in the repo" — this was false: deploy/wonder-app-vd03/ is present in the working tree, merely gitignored (.gitignore:48: /deploy/ — production config kept out of version control, not absent), and was actively maintained here (PLAN-07 edited its _comment_Security). Correcting the record: the presence claim was wrong; only the version-control-tracking is intentionally absent. PLAN-R2-01 Tasks 5-6 applied the three overlay edits directly on-disk (no git add — the artifact stays gitignored; sc.exe failure service-recovery actions were already present on disk, so T6 only added the missing failureflag). The code/validator/doc halves of all three original tasks had already shipped (AllowSingleNodeCluster flag + validator, the IHostApplicationLifetime process-exit watchdog, the oldest-member Traefik/Host doc reconciliation + TLS roadmap note). Remaining owner action: sync the artifact to wonder-app-vd03 and restart services — appsettings take effect on restart; failureflag on re-running install.ps1 §7 (or running the two sc.exe lines manually) — per the RUNBOOK troubleshooting row added by T6. Without NodeName every audit row from that deployment stamps a NULL SourceNode; without the failure-actions flag a self-downed (non-crash-exit) node will not auto-restart.

Plan deviations during Wave 1 PLAN-03 execution (2026-07-09)

• Task 15 (S6) — deploy-success reporting redesigned: readiness handshake, not swallow-only. The plan's Task 15 relied on the Terminated signal beating the persistence result, so a stale persistence Success could simply be swallowed once the init-failure path had already replied Failed. In practice the store commits FIRST (the optimistic StoreDeployedConfigAsync completes before the child's async PreStart throws), so the swallow-only guard still reported Success for an actor that then died — the exact S6 bug. Fix as shipped makes the join deterministic: InstanceActor.PreStart now sends a new InstanceActorInitialized readiness message to the DeploymentManager as its final init step, and deployment Success requires both the persistence commit and that signal (InFlightDeploy.Persisted && Initialized); an actor that dies during init never signals readiness, so the Terminated fallback fails the deployment and rolls back the optimistic state. A second, related bug was fixed at the same time: the optimistic Store… and the rollback Remove… were independent Task.Runs with no ordering guarantee, so the persisted-row rollback is now deferred until the store commits (_initFailedPendingRowRemoval) and can never race ahead of it. New public surface: Messages/InstanceActorInitialized.cs (additive). Follow-up owner: PLAN-03 Task 26 — the design-doc updates must describe the two-signal deploy-success join + the readiness message (alongside Task 4's already-flagged synchronous-compile-gate deviation). No further code work outstanding; this is a doc-capture follow-up.

Pre-existing failure discovered during Wave 1 PLAN-03 execution — owner PLAN-07 (2026-07-09)

• ✅ RESOLVED 2026-07-09 — 3 CentralUI.Tests / SecuredWritesTests render tests fixed by registering a stub IBrowseService in the bUnit harness; suite now 7/7 green. Original report retained below for history. IBrowseService not registered in the page's bUnit harness (PLAN-07 / Secured Writes, NOT PLAN-03). PLAN-03's final full-solution dotnet test surfaced 3 failures in SecuredWritesTests (Operator_SeesSubmitForm, Operator_Submit_CallsServiceWithEnteredValues, Verifier_OwnSubmission_HasApproveAndRejectDisabled), all InvalidOperationException: Cannot provide a value for property 'BrowseService' on type 'NodeBrowserDialog' — no registered service of type 'IBrowseService'. Root cause: the Secured Writes page (Components/Pages/Operations/SecuredWrites.razor) renders Components/Dialogs/NodeBrowserDialog.razor, which @injects IBrowseService; the test fixture (SecuredWritesTests) registers _service/_siteRepo/_dialog/auth but not a fake IBrowseService, so rendering the child dialog throws. Confirmed pre-existing and out of PLAN-03 scope — the failing files were last touched by commits outside the PLAN-03 session (1a7e7351 page/test, 9cff87fe dialog), and PLAN-03 never touches Secured Writes / CentralUI. Merged to main (c7a0c922) with this red present because it is not a regression from this branch. Owner: PLAN-07 — register a stub IBrowseService in the SecuredWritesTests Services collection before RenderPage() (or in the shared bUnit fixture). See PLAN-07 "Post-plan known issues".
