Component-AuditLog Retention & Purge describes the archive: directory and
layout, the three files, consistency with the hash chain (SHARED read,
guarded switch, anchor = archived chain end), fail-closed purge, retention
interplay (per-channel overrides are not archived, their tombstones are),
verify/read, and the AuditLog:Archive configuration. alog.md §13.6/§15.2/§16,
CLAUDE.md, HighLevelReqs AL-12, Component-CLI, Component-ManagementService,
docs/components/{CLI,ManagementService}.md and the CLI README drop the
"deferred / 501" wording and document `audit archive list|verify` and the
parquet export.

The data plane answers a broken inbound method with the generic "Script
compilation failed for this method"; the Roslyn diagnostic reached only the
central log, and the known-bad cache could not be observed or reset per method.
- InboundScriptExecutor keeps the diagnostics with each known-bad record and
exposes GetCompileState(name, currentScript): IsCompiled / IsKnownBad /
LastCompileError, judged against the current script text (a record for older
text is reported as not compiled yet).
- Management: ValidateApiMethodCommand (compile the stored script, return
ApiMethodCompileResult, register nothing, cache untouched) and
RecompileApiMethodCommand (CompileAndRegister without re-sending the entity,
drops the node's ApiMethodCache row, audited "Recompile"). Both Designer, like
UpdateApiMethod; dispatched through the shared ApiMethodCompileOperations.
GetApiMethod keeps the entity fields top-level and adds isCompiled,
isKnownBad, lastCompileError and compileStateNode. Compile state is per
central node and every result names the node.
- CLI: api-method validate --id, api-method recompile --id.
- Central UI: the API-method edit page shows the saved script's compile state
and last error, with Validate and Recompile actions (same operations, same
Designer gate, fresh DI scope).
- RequiredRoleMatrixTests entries; ManagementSurfaceParityTests covers the new
CLI leaves; ApiMethodCompileDiagnosticsTests + an executor CompileState test.
- Docs: CLI README, Component-CLI/ManagementService/InboundAPI, components/*.

Health page gains PendingUpdatesHealthTiles (stale instances / sites with stale
artifacts, Deployer+Administrator only, site-scope narrowed, shared cache). New
GetPendingUpdates management command (Deployer) and 'health pending-updates' CLI
leaf. Flatten/cache computation untouched; the command reads
IPendingUpdatesEvaluator directly because the UI cache is not reachable from
ManagementService.

Phase 0 of the ClusterClient→gRPC migration
(docs/plans/2026-07-22-clusterclient-to-grpc-plan.md). Standalone hardening: it
closes a gap that exists today and is a precondition for moving command/control
onto gRPC in later phases.
T0.1 — delete the ManagementActor ClusterClientReceptionist registration.
It was built for an out-of-cluster CLI that was never written: the shipped CLI
speaks HTTP Basic to /management, which asks the actor in-process through
ManagementActorHolder. Nothing in the repo ever sent to /user/management. The
actor still runs there; only the cross-boundary advertisement is gone. Six
documents claimed the CLI used ClusterClient — including the CLI's own README
"Architecture Notes" — and are corrected here rather than left to rot.
T0.2 — record, do not port, the dead integration-routing path.
IntegrationCallRequest is unwired at BOTH ends: RouteIntegrationCallAsync has
zero callers anywhere, and RegisterLocalHandler(Integration, …) appears only in
a test, so production always answers "Integration handler not available". It is
excluded from the gRPC contract (28 of 29 commands migrate) rather than
enshrined on an additive-only wire format, and deleting it during a
transport migration would mix a behavioural change into a change whose whole
value is that behaviour is identical. See
docs/known-issues/2026-07-22-integration-call-routing-is-dead-code.md.
T0.3 — preshared-key authentication on SiteStreamService.
The service shipped with no auth at all: plaintext h2c, no interceptor, so
anything that could reach a site node's :8083 could open a live data stream or
read audit rows back via PullAuditEvents/PullSiteCalls. ControlPlaneAuthInterceptor
now gates /sitestream.SiteStreamService/ — modeled on LocalDbSyncAuthInterceptor
(constant-time compare, fail-closed, PermissionDenied) but gating a SET of
service prefixes so phases 1A/1B add services rather than interceptors. LocalDb
sync keeps its own separate key: it authenticates the pair partner, not central,
and collapsing the two would make a site's central-facing key also admit writes
into its database.
Keys are per site (SB-GRPC-PSK-<siteId>), never fleet-wide, so a compromised
site yields only its own. Central attaches them through ControlPlaneCredentials,
which binds CallCredentials to the channel — covering unary and streaming
uniformly, and letting the key resolve asynchronously, which a client
interceptor could not do without blocking. All three central→site channel
creation sites go through it (SiteStreamGrpcClient and both audit pull invokers);
the pull invokers' channel caches are re-keyed by (site, endpoint) because
credentials are per-site and bound to the channel.
Two decisions beyond the plan:
* StartupValidator now requires GrpcPsk on Site nodes. The plan specified only
the runtime gate, but fail-closed with no boot check produces a node that
joins, answers heartbeats and reports healthy while refusing every stream,
audit pull and telemetry ingest — silent and total. Same reasoning as the
existing inbound API-key pepper rule.
* Added Communication:SitePsks as a central-side key map. The plan assumed
central would read the store, seeded via a dev KEK; the docker rig
deliberately boots with no master key, so store-only resolution would leave
it unable to dial its own sites. The store stays primary — it is the only
source that can serve a site added at runtime — with the map covering
key-less hosts and one-off pins. Neither source falling back to
"unauthenticated" is the invariant.
T0.4 — dev keys on both rigs and tests.
34 tests. The seven that matter most exercise a real in-process gRPC stack over
TestServer: the unit tests on either side of the wire would both stay green if
the halves disagreed, and gRPC refuses call credentials on a plaintext channel
by default — the UnsafeUseInsecureChannelCallCredentials opt-in is only provable
by making a real call. They confirm correct key passes on unary AND streaming,
wrong key and no-credentials both get PermissionDenied, and an unresolvable key
fails the call with nothing reaching the service.
OPERATIONAL: a site node upgraded to this build without a key will not boot.
That includes the gitignored deploy/wonder-app-vd03/ overlay.
