Summary

  • Complete P02d-2: explicit protected-content policy, exact definition/locale contracts, three Tenancy and six Education authoring commands, and complete scoped demo curricula through the real request pipeline.
  • Make seed converge safely on fresh/repeated/interrupted/concurrent runs, reject mismatches and incompatible Active revisions, and enforce contextual ownership verification with source/caller guards.
  • Align current-state, deployment and decision documentation. ADR-0050/0051 are Accepted; the optional Course Marketplace direction and Phase 09a remain Proposed and introduce no commerce implementation.

Approach

Publication and content access are independent. Course creation selects an explicit closed policy; legacy content backfills to enrollment_required. Exact revision and enabled-locale checks precede mutation. Commands derive tenant/organization authority from context and authorized parents, reserve localized slugs at translation insertion, and keep Course/Lesson publication independent.

Every seed read/write uses a fresh contextual ISender scope as learnstack_app. Completed acts skip writers; typed races require one fresh exact postcondition. Seed checks the logical key's Active identity before registration and uses a transaction-level RequireNoIncumbent publication precondition. Ordinary customization revision succession remains available. Post-save failures mark the ambient unit rollback-only, including when an outer request absorbs the refusal.

SeedData owns the complete inventory: two tenants, four organizations, two hosts, three locales, four content types, four taxonomies/fifteen bands, two themes, eight courses, ten lessons and twenty-seven translations. English and Yoga differ in actual schema shape, labels, bodies, taxonomy and branding. All four implementation steps completed two fresh independent review rounds; verified findings are fixed and recorded in the packet delivery record.

Tests

  • Final head 1613143: all five required CI checks passed (CI run); optional CodeRabbit status is pending. The local verification below includes the latest branding correction.
  • Release build: 0 warnings/errors; full dotnet format --no-restore --verify-no-changes passed.
  • Backend: 2,594 passed, 0 failed, 0 skipped — 1,577 unit, 184 architecture, 1 contract, 171 Docker-free integration, 661 Docker integration. TRX failure counters and execution/zero-skip guards checked.
  • The complete Docker run covers Education writers, policy migration, Customization publication and Seeder. Covers real CLI 0/0/1 exits, interrupted/repeated seeds, actual non-provisioning race recovery, absorbed Course/Lesson post-save refusals and both Customization MUST-audit replacement rollbacks.
  • All five EF chains: no pending model changes; complete Docker suite proves forward/down/reapply, populated access-policy preservation and invalid legacy locale refusal.
  • Frontend frozen install, typecheck, lint, build and all 13 Vitest tests passed. Four default/gated dev/e2e compose configurations and actionlint passed.
  • Supplemental sweep of 45 Markdown files: 2,901 local link occurrences and 580 fragments checked outside fenced code; added prose wrapping, git diff --check and strict commit hooks passed. Frozen P02d-1 record remains byte-identical to the accepted implementation baseline.

Review corrections

  • Exact presentation resolution returns a bounded /properties validation failure for non-object roots and missing/non-object properties; eleven regression inputs preserve the optional legacy path.

  • Migration reversal finds the named access-policy migration and proves restricted backfill after both Up applications. Rollback tests now directly cover Lesson absorption, both Customization MUST-audit replacements and incumbent rollback-only refusal.

  • A deterministic translation race witnesses two real seed writers, one successful and one refused act, fresh exact-state verification for identical/divergent payloads before reporting completion, and unchanged all-outcome rerun state. The losing-race recheck mutant is killed by the divergent case.

  • ADR-0050/0051 retain their historical acceptance text with dated current delivery disclosures and amendments. All affected current-state carriers separate shipped P02d-2 policy/writers/profile/seed from pending P02d-4 public reads, P02d-6 rendering and Phase 07 grants. Localization keeps the raw-delete default gap; contrast saving is refused; the default entitlement provider grants every feature and unlimited limits.

  • Prior correction-review rounds completed; the verified proof gap was fixed and mutation-tested. The additional corrections also completed two fresh independent code and documentation review rounds. Round 1's unused-helper finding was fixed and revalidated; round 2 approved with no open actionable finding. All dispositions are recorded in the packet delivery record.

  • Verified skips: seed branding is create-only, so replacement-version requirements do not apply; authoritative writers already validate exact persisted references, without a new whole-declaration preflight; existing inventory and complete audit snapshots already prove shared tenant-local slugs and all-outcome repeat neutrality.

  • Deleted tenants are excluded from the write-store lookup; a real application-role test proves retained navigations on live roots and refusal after deletion. Branding independently checks that the announced tenant exists and is not soft-deleted before any setting access; both create/replace are refused with not_found, while live Trial tenants remain supported. The scalar reader is wired in both runtime roots. Four application-role cases prove no setting access, unchanged stored value/version and no additional successful audit; the seeder-root deletion proof and unit scope-first witness also cover the guard.

  • API and direct Seeder execution share the application-role pool guard, including per-connection direct/transitive bypass rejection and credential-safe parsing failures. The seed fence checks actual IL for direct EF mutation/ad hoc SQL.

  • Permanent aggregate-census controls cover fused ports, two ports, notifications, internal constructors and key-only writes. Eight controlled mutants fail the intended guards; source is byte-restored and the positive architecture suite passes again.

  • Narrow persisted proofs cover cross-tenant locale/Education writes, real exact-version locale races, identifier-conflict details, CHECK removal on Down, undeclared-locale seed refusal and registry non-emptiness. Malformed presentation JSON returns a validation result.

  • Additional findings and suggestions were verified individually. Optional scanners, unsupported future surfaces and already-satisfied contracts were not turned into unrelated production changes; reasons are in the delivery record.

  • After the unused-helper cleanup: Release build remains 0 warnings/errors; credential guard tests 20/20, architecture 184/184 and scoped format verification pass.

  • The branding correction 50518e7 completed two fresh independent GPT-5.5 (high) read-only review rounds; both approved without an actionable finding. 1613143 records the closeout without changing reviewed production code. Targeted Tenancy tests pass 19/19; final suite evidence is 2,594 passing backend cases.

Risk

  • Tenant/organization isolation and the write boundary are affected: contextual reads, scoped writers and database backstops are covered under ADR-0003, ADR-0040 and ADR-0042. Normal seed writes use neither an owner nor BYPASSRLS.
  • Generic TenantSetting JSON is wholly PII-redacted in audit capture. Public branding allowlisting remains a separate later read boundary.
  • No public endpoint, enrollment/access grant, authentication or browser demo is delivered. P02d-3 owns read internals; P02d-4 owns public eligibility/hidden-response/query-plan proofs; P02d-5–7 own transport/render/demo.

Migration / Rollback

Apply the existing migration chains through make migrate as learnstack_migration before running seed. Two additive migrations introduce Course content access (restricted default/backfill) and reject disabled default tenant locales. An invalid legacy locale configuration stops migration and requires explicit repair; it is never silently rewritten.

Technical Down/reapply is proved only in disposable databases. Removing live access policy is not an approved production rollback: it would remove the durable protection boundary. Use a reviewed forward correction for live policy changes. Repeat seed never overwrites mismatched existing data or retires a different Active customization revision.

backend/tests/LearnStack.Tests.Integration/Database/CourseContentAccessMigrationTests.cs (1)

26-26: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Name the content-access migration's predecessor instead of computing "second-to-last migration".

Line 26 picks the rollback target with GetMigrations().Reverse().Skip(1).First(). Today that is the predecessor of 20261001233219_add_course_content_access. When a later Education migration lands, this expression will revert only the newest migration and leave content_access in place:

  • LegacyRows then inserts into a schema that already has the column and its default.
  • The test can still pass, but it no longer proves anything about the legacy backfill it is named for.

P02d2FoundationTests.A_disabled_legacy_default_refuses_an_enabled_locale_independently_of_default_count already uses the stable form: it pins its predecessor by name.

♻️ Proposed fix
-        var previous = context.Database.GetMigrations().Reverse().Skip(1).First();
+        var migrations = context.Database.GetMigrations().ToList();
+        var target = migrations.IndexOf("20261001233219_add_course_content_access");
+        target.Should().BePositive("the content-access migration must exist and have a predecessor");
+        var previous = migrations[target - 1];

Refuse malformed stored presentation shapes through Result rather than
exceptions. Add direct publication rollback and real seed race proofs,
and pin migration reversal to the named policy migration.

Align delivery carriers with shipped P02d-2 scope while preserving the
accepted ADR history and later public-read and rendering boundaries.

ADR: 0040, 0041, 0050, 0051
Module: customization, education, tenancy
Record both independent first-round approvals and the complete backend
verification after the corrections. Wrap the added prose without
changing delivery scope or accepted decisions.

ADR: 0041, 0050, 0051
Preserve delivery wording while keeping the correction record within
the documentation prose width.
Make a raced translation's exact-state recheck falsifiable before the
runner reports completion. Different payloads must refuse the loser;
a later final-state check cannot substitute for this proof.

The recheck mutant is killed and the production file is restored.
Record complete validation and align the standards current-state date.

ADR: 0040, 0050, 0051
Module: education, tenancy, customization
Record the fresh follow-up approval of the falsifiable seed race proof
and keep the maintainer merge boundary explicit.

Review comments at
@backend/src/Modules/Tenancy/LearnStack.Modules.Tenancy.Infrastructure/Persistence/TenancyWriteStores.cs:
- Around line 50-53: Update `FindAsync` in the tenant write store to exclude
tenants whose `DeletedAt` is set, while preserving the existing includes, ID
match, and cancellation-token handling.

Review comments at
@docs/decisions/0049-institution-sites-and-course-marketplace.md:
- Around line 31-33: Update the P02d-2 status sentence near the ADR-0050
reference to reflect that the application writers have been delivered,
consistent with the status recorded later in the document; alternatively,
clearly mark the sentence as historical.

Review comments at @docs/modules/tenancy/permissions.md:
- Around line 32-35: Update the route and caller description to distinguish
current from planned behavior: state that none of the writers currently has a
registered HTTP endpoint and scope the seeder-only claim to the current route
set. Describe Phase 02c’s planned tenant-creation endpoint as creating the
default organization and its host-mapping endpoint as a source for
MapHostToTenantCommand; do not imply a direct Hub endpoint for
CreateOrganizationCommand.

Keep deleted tenant roots out of supported writes and enforce the same
application-role boundary in the seeder and API. Strengthen aggregate
and seed persistence fences with planted controls and measured mutants.

Prove narrow isolation, concurrency and refusal cases; reconcile current
writer and presentation delivery without changing accepted decisions.
Record verified review dispositions and complete positive validation.

ADR: 0003, 0040, 0042, 0050, 0051
Module: Tenancy, Customization, Education
Keep the shared application-role builder as the only active credential
redaction authority after extraction. Remove the unused API helper,
wrap catalogue prose, and record independent correction review results.

ADR: 0003
Module: Tenancy, Education, Customization
Record both fresh second-round approvals and the exact reviewed range.
Keep delivery evidence distinct from pending maintainer review and merge,
while preserving the frozen P02d-1 record.

SetTenantBrandingCommandHandler allows both creation and replacement after it resolves a tenant-wide context. TenantSettingWriteStore does not check Tenant.DeletedAt, and the settings write policy checks only tenant and organization IDs. Therefore, a null ExpectedVersion can insert branding, and a matching ExpectedVersion can update branding for a soft-deleted tenant. Apply the active-tenant check at the handler or setting-store boundary, consistent with locale writes.

Suggested fix
+        var tenant = await tenants.FindActiveAsync(tenantContext.TenantId, cancellationToken);
+        if (tenant is null)
+        {
+            return TenantWriteFailures.Code<TenantBrandingDto>("lockey_not_found");
+        }
+
         var setting = await settings.FindAsync(TenantSettingId.From(request.SettingId), cancellationToken);

In SetTenantBrandingCommandHandler, after validating the tenant scope and before
loading or writing a setting, require the tenant to be active; return the
existing not-found failure when it is missing or soft-deleted so neither
creation nor replacement proceeds.

Require a live announced tenant before touching a setting, so stale
contexts cannot create or replace branding after tenant deletion. Keep
the check read-only and preserve Trial tenants in both runtime roots.

ADR: 0003, 0040, 0042
Record both fresh independent approvals and the verified tenant guard
evidence without changing the reviewed production code.
