Gitea renders mermaid inline, so the flow/state/hierarchy/DAG diagrams
move to text-in-markdown: auto-layout (removes the manual overlap-prone
draw.io step), diffable source, no committed binaries, and a dark-text
theme so labels stay legible. Keep draw.io PNGs only for the two complex
bespoke diagrams (logical architecture, env2 topology) where pixel
control still wins. All 24 mermaid blocks validated by rendering.
Replace ASCII-art diagrams across the README and docs/ with editable
.drawio sources plus exported PNGs, so the diagrams render clearly in
rendered markdown and can be maintained/regenerated instead of being
hand-edited as fragile text art. Non-diagram blocks (code, folder
trees, UI wireframes) were left as text.
- Adds SourceNode varchar(64) NULL to AuditLog, Notifications, and SiteCalls
tables with role-name semantics: node-a/node-b for site rows (qualified by
SourceSiteId), central-a/central-b for central direct-write rows.
- New IX_AuditLog_Node_Occurred (SourceNode, OccurredAtUtc) index.
- Reframes CLAUDE.md from documentation-only to implementation project.
- Adds docs/plans/2026-05-23-audit-source-node.md + tasks.json companion.
Final cross-bundle reviewer identified 7 inconsistencies that the per-bundle
reviewers couldn't see; all fixed in one logical commit.
Critical:
- HighLevelReqs AL-3: drop 'then upsert-on-newer-status' — AuditLog is
strictly append-only (correct for SiteCalls/Notifications, wrong for
the immutable AuditLog shadow).
- Component-AuditLog Error rate KPI: align with HealthMonitoring's
exclusion list (Success/Delivered/Enqueued) rather than just non-Success;
otherwise every Delivered notification or Enqueued cached call would be
counted as an error.
Important:
- Component-AuditLog line 154: ISiteAuditWriter -> IAuditWriter (canonical
name per Commons and the rest of this doc).
- Component-AuditLog Central direct-write paragraph: convert remaining
slash notation (ApiInbound/Completed, Notification/Attempt,
Notification/Terminal) to dot notation used everywhere else.
- Component-ClusterInfrastructure: scope SiteCallAuditActor to
reconciliation + KPIs + Retry/Discard relay; cached-telemetry ingest is
AuditLogIngestActor's role per Combined Telemetry contract.
- Component-CentralUI Audit Log page: state the OperationalAudit read
permission and the read-vs-export split (matching CLI doc).
- Component-NotificationOutbox: add never-fail-the-action invariant for
dispatcher audit writes.
Minor:
- Component-InboundAPI: 'Non-blocking semantics' was ambiguous (could be
read as async); reword to 'Fail-soft' — the write is still synchronous
before flush, but failures are caught and don't change the response.
- Component-CLI: realign audit-query/audit-export flags to actually match
the Central UI Audit Log filter set (channel, kind, status, site,
instance, target, actor, correlation-id, errors-only); drop --user and
--entity-id which are IAuditService concepts, not Audit Log columns.
- Component-AuditLog KPI tile names: 'Volume/Error rate/Backlog' ->
'Audit volume/Audit error rate/Audit backlog' (matches Central UI and
Health Monitoring); drop the two orphan KPIs (Top inbound callers, Top
outbound 5xx) that were never surfaced anywhere.
- Component-AuditLog Interactions: re-attribute DbOutbound emissions to
ESG (where Database.* lives) with a note that Site Runtime is the API
surface for scripts.
- HighLevelReqs AL-12: drop 'and reconciliation operations' (CLI has no
reconcile command; reconciliation is an internal self-healing pull).
Add note that verify-chain becomes operational once AL-11's hash chain
ships.
