Summary

Authenticate tenant API requests under ADR-0064 and expose host-backed GET /api/v1/account/site through the physical read-only owner. Invalid credentials return 401; absent AccountSite credentials remain masked 404. Credential-free public rendering remains independent of Keycloak.

ADR-0065 bounds mismatch audit attempts to 600 per defended tenant/instance/minute, shared across actors and scopes. Suppression preserves refusal, attributed logging and a closed counter. Native HTTP/DNS metrics omit destination identities process-wide and disable exemplars, including environment overrides.

ADR-0066 owns 4096 retained issuer/subject partitions plus at most 128 retiring limiters. One joined cleanup owner preserves failures; retained subjects keep service after a sticky fault while new subjects receive 503/30-second retry hints. Quota/capacity remain 429; refusals apply no-store, including unmatched classified paths.

Systematic corrections close the global/provider/action MVC and endpoint-authorization censuses, transitive handler and attribute metadata escape paths, consumed read-mode and served-contract proof gaps. Reader, recorder, startup, containment and cleanup controls exercise the actual boundaries. SDK local refusals remain typed and make zero forbidden fetches. Demo receipts bind both report members and the observed source tree; native exit, cancellation, daemon and cleanup outcomes preserve their actual owner. Historical proposal and delivery claims are reconciled without rewriting Accepted ADR bodies.

Approach

The source checkpoints, paired byte digests and closed failure diagnostics implement ADR-0056's existing invocation identity, stale-report refusal and bounded sanitized failure-evidence requirements. They do not introduce a new trust boundary, hermetic attestation, failure-response policy, budget or execution topology. An independent corpus reinspection confirms that Testing 06's existing ADR-0056 derivation covers these implementation mechanisms; no new decision or amendment is required.

The measured CI repair refreshes 242 Architecture selector weights from 406 Passed rows in five complete hosted TRXs, with API-bound ZIP/source/attempt provenance and exact tick arithmetic. All 21 selectors from the incomplete shard keep their previous weights. Counts (6 Architecture, 12 ordinary), whole-method/theory-row grouping, assignment algorithm, case population, bounds, required checks and execution budgets are unchanged. ADR-0063 authorizes the timing refresh; the two named timing-revision assignments below qualify the unchanged plan on their recorded source; the subsequent guard commit has its own complete assignment.

The final provenance follow-up requires both source and run identities for hosted_trx records, preserving the disclosed nullable historical local/console shapes. The actual-owner control fails on all three missing-identity combinations before the fix and passes afterwards. This validates record shape; independent API/archive/TRX verification remains the authenticity boundary. The plan bytes, weights, assignment algorithm and fixture lifetime do not change. ADR-0063 therefore requires one fresh complete assignment for this normal push.

Tests

Final head: 419e456260dc2023f3e6d538a46ede8b1d7e8f20. Run 39431896517, attempt 1: 27/27 jobs successful. Tested merge be8417c3a289d26e9062bd40bf163d51987d3e11 includes this exact head; independent Actions API merge/head/local tree equality verifies.

  • Backend: 5,847 passed, zero failed/skipped — Unit 2,616; Architecture 433; Contract 5; non-Docker Integration 287; ordinary Docker 2,475; native 31. API-bound job/artifact IDs, ZIP digests/windows, file hashes, source/attempt identities and complete discovered case unions reproduce both hosted aggregates (3,341 + 2,506). All 20 workers complete naturally with joined cleanup and no forced cleanup; native refusal evidence is empty.
  • Frontend: 1,699 passed (1,627 web + 72 SDK), zero skips/todos. Hosted typecheck, lint and production build pass. OpenAPI, secret scan and meta checks pass.
  • Public demo: 27 JSON/HTML pairs; both member byte digests and exact commit/tree, build, invocation, URL/run, configuration and browser identities verify. 134 API completions, all HTTP 200; proof 651.490s; cleanup 12.839s. Nine navigations, 24 visibility controls, both TLS refusals and timeout control pass. All owned processes, Compose, private files, environment and lock are removed. Hard JS/CLS/accessibility budgets pass; 8 URL groups retain nonblocking timing warnings. Thresholds and browser flags are unchanged.
  • Unchanged-plan A/B qualification: run 39424514759, A and B each pass 27/27 on source b3abbce65ba60ae4165b1eb09bd44d8644e7843d. Independently verified identical 5,847 case IDs, observed SDK version and console/adapter hashes; actual Architecture/ordinary/SharedSchema co-membership differs. Both have 1,699 frontend passes, 31 native cases, 27 report pairs and natural cleanup. All 54 job IDs and 46 backend/demo artifact IDs are distinct. These historical-source receipts qualify the unchanged timing plan; they are not substituted for the new final-head run above. Plan digest 85ce77743fd83d924060ad7008899595908ec4fd466597078ae6509e022db01d. Assignment digests A 074241fb4166bddca4dd3266be7064299867e868c1bd3d16d0c7eeac45783482, B 45c560552e065b7eebd0da53bbd3e7c8e55a39ede516dd30398960dbb3850e7d; the new final run retains A and the same complete manifest.
  • Review and local controls: all three correction steps completed two fresh independent review rounds, plus two fresh independent rounds for the provenance follow-up. Verified findings are fixed and committed. Read-only source inspections are distinct from execution. Before/after real-child controls and the missing-provenance controls demonstrate actual failure detection. Release builds have zero warnings/errors; final corpus controls, seven ADR-parser controls, 52 combined plan/result controls, 16 separate result controls and 2,276 relative links/fragments pass.
  • Earlier failed qualification: source 00a7877e / run 39417319998 was not qualified: attempt 1 refused ordinary-9 Docker baseline inventory before tests; attempt 2 reached the Architecture-3 deadline. Aggregates refused incomplete results. Neither successful sibling nor incomplete receipt is reused as final-head evidence.
  • Branch protection: the same seven required context names, original GitHub Actions app bindings and strict checking. Correction/qualification passes relax no test population, timeout, required check, browser flag or audit threshold.

Risk

This changes authentication/isolation behavior under ADR-0064/0065/0066 and their dated disclosures; no schema, role, grant or RLS changes occur. A caller can consume a tenant's shared durable audit allowance; later actors can lose rows during that window. Warning volume remains unbounded and per-instance limits multiply. Native metric destination and exemplar correlation are unavailable; ordinary traces/logs remain observable.

The shared subject registry can deny new subjects from other tenants when live slots are occupied. A single blocked disposal can indefinitely delay its owning request and joined shutdown. Sticky cleanup fault requires qualified instance replacement; a retry hint promises neither recovery nor a free slot. The 4096 ceiling is not measured production sizing.

P02b-6 real issuance and P02b-7 BFF custody remain incomplete. Phase 03 must install runtime deny-by-default before its first permission-sensitive endpoint. Phase 11 owns measured/distributed capacity, issuer readiness, mapped readiness, diagnostic alerts and exercised runbooks before production exposure. Immediate revocation and independent end-to-end 600/minute throughput are not promised.

Demo source checks are observations, not hermetic build attestation: ignored inputs and edits restored between checkpoints remain outside the claim. Timing weights remain advisory estimates; these two successful assignments do not promise future runner performance. Existing production-activation owners and boundaries are unchanged.

Migration / Rollback

Configure Authentication:Tenant:Issuer as the canonical tenant-realm HTTPS origin reachable from the API. Private/split-horizon DNS must preserve that exact issuer; no separate metadata origin is introduced. Startup validates configuration without network I/O. Loopback HTTP remains Development-only. No data migration; roll back API and generated SDK together.

🟡 Minor · Fix the null-conditional short-circuit in the local NoStore… · PublicSiteHttpTests.cs:328-333

backend/tests/LearnStack.Tests.Integration/Database/PublicSiteHttpTests.cs:328-333
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix the null-conditional short-circuit in the local NoStore helper.

response.Headers.CacheControl?.NoStore.Should().BeTrue() skips the whole assertion when Cache-Control is absent. A response without any Cache-Control header therefore passes the no-store check. Every caller of Error and GetAndHeadError in this file uses this helper, including the changed 405 assertion at Line 282-283.

This PR already fixed the same defect in TenantAuthenticationHttpTests.NoStore, and AssertNoStoreHeaderControls in AuthenticatedRateLimitTests.Admission.cs adds controls for that fix. This copy still has the old form. Apply the same fix here, or call the shared helper.

🐛 Proposed fix
     private static void NoStore(HttpResponseMessage response)
     {
-        response.Headers.CacheControl?.NoStore.Should().BeTrue();
-        response.Headers.ETag.Should().BeNull();
-        response.Content.Headers.LastModified.Should().BeNull();
+        TenantAuthenticationHttpTests.NoStore(response);
     }

ADR: 0036, 0040, 0041, 0052, 0064, 0065, 0066
Extend the bounded filter census to effective provider composition and

ADR: 0053, 0054, 0056, 0064
Publish output refusal before physical shutdown and keep the same first
daemon error for every observer. Classify native coordinator cancellation
from its owned signal without replacing known faults or cleanup failures.

ADR: 0056
Keep the first native failure authoritative when paused or inherited
output delays close, while successful capture and physical cleanup
still retain their existing completion bounds. Real-child controls
prove the failure ordering and preserve complete successful output.

ADR: 0056, 0064
A daemon's zero exit is still an unexpected failure. Observe it apart
from ordinary command success so delayed streams cannot replace the
first daemon outcome, while complete command output remains required.

ADR: 0056, 0064
Record verified fixes and independent follow-up closure while keeping
current-source hosted qualification separate from historical receipts,
local checks, production activation and maintainer merge approval.

ADR: 0056, 0064, 0065, 0066

Comment thread docs/standards/06-testing.md
A censored assignment colocated expensive serial controls and exhausted
its existing deadline. Refresh only completed hosted selector costs,
retain unknown estimates honestly, and require both final-source layouts
without changing membership, topology, algorithm or time budgets.

ADR: 0063, 0064
Record both independent provenance and contract review rounds while
requiring fresh complete A/B evidence for the revised timing plan.
Clarify the existing distinction from ordinary future pushes without
changing any execution or qualification policy.

ADR: 0063, 0064

Require non-null source and run identities for hosted TRX timing records.
Keep historical local and console source shapes intact. Plant all three
missing-identity combinations against the actual plan validator.

ADR: 0063
Record both independent review rounds and keep historical plan qualification
separate from the final-source full assignment required after the guard fix.

ADR: 0063

Present this qualification as concise bullets.

The added record places run results, the parser correction, review receipts, and remaining qualification in multi-sentence paragraphs. Split these items into short bullets so readers can scan the evidence. As per coding guidelines: “Short and declarative — heading + bullets over essay paragraphs.”
