docs: close Packet 7 against what actually merged - #16
Merged
Conversation
The delivery record was written at packet close, and fifteen commits landed after it from the pull request's own review rounds — including the sharpest defect of the packet. A record that stopped before them would be a false account, so it now carries a § What the pull-request review found: the shipped invariant that did not hold (PromoteDefault's order is not EF's, and this packet's PR description cited it as the migration's safety rationale), the canonical template that admitted an organization-scoped session to tenant-wide rows, three credential and transaction gaps, two architecture rules with escapes, three ADR edits made outside the rules that govern them, and two findings the measurement refuted. The measured total moves with it: 1208, counted from a run. Three architecture rules the review added were never registered — Every_Write_Port_Is_Countable_Or_Enumerated, which closes the census's blind spot for ports that do not derive; Out_Of_Band_Setters_Open_Read_Only_Transactions, which a behavioural test cannot express; and Registering_The_Pipeline_Twice_Registers_It_Once, which pins a property MediatR provides and the repository depends on. Database Standards now names ADR-0003 Amendment 4 in its Derives from header, because the template it carries is what that amendment corrects.

Reviewer's GuideDocumentation-only changes close Packet 7 against the merged pull request by incorporating post-close review findings, updating the measured test record, capturing shipped and non-shipped defects, registering three architecture rules, and linking the corrected database template to ADR-0003 Amendment 4.

- **Status:** **Implemented** (Packet 7, `LearnStack.Tests.Architecture`).
- **Phase:** 02a Packet 7.
+#### `Every_Write_Port_Is_Countable_Or_Enumerated`
+
+- **Asserts:** every interface in a production assembly whose method takes a type from a
+ module's `Domain` assembly either derives from `IAggregateWriteStore<TRoot, TId>` — and
+ is therefore visible to the cross-aggregate census above — or appears on a literal
+ allow-list. The list holds one name: `IPlatformHostMappingStore`.
+- **Why it exists.** The census counts derivations, so a port that does not derive is
+ invisible to it. One already is, deliberately: `PlatformHostMapping` is a projection
</code_context>
<issue_to_address>
**issue (broader_impact):** The catalogue claims this rule detects every interface method that takes a type from a module's `Domain` assembly, but the implementation only checks whether the parameter's immediate `Assembly` is a domain assembly. Parameters such as `IEnumerable<Course>`, `Task<Course>`, or another wrapper around a domain type are therefore invisible to the rule despite satisfying the documented assertion.
**Triggers:** When a write port accepts a collection, task, tuple, or other generic wrapper containing a domain type.
**Suggested fix:** Define and document a recursive type-shape check that inspects generic arguments and relevant array/by-reference element types, or narrow the catalogue assertion to direct domain-assembly parameters.

[ADR-0003 Tenant Isolation Defense in Depth](../decisions/0003-tenant-isolation-defense-in-depth.md)

<issue_to_address>
**nitpick:** The standard now derives from ADR-0003 Amendment 4, but ADR-0003's status header still lists only Amendments 1–3. A reader following the authority metadata cannot tell that Amendment 4 is part of the ADR's current status, and the ADR contains another section also numbered Amendment 4, making the new dependency ambiguous.
**Triggers:** When consumers use ADR status metadata or amendment numbering to determine the current database-isolation authority.
**Suggested fix:** Update ADR-0003's status line to include the dated write-guard Amendment 4 and renumber or otherwise disambiguate the pre-existing stale-table amendment.

ADR-0003 already had an Amendment 4 — the 2026-08-29 note that its Phase 02a table list had gone stale — and the write-guard amendment was appended with the same number. An erratum inside the same file says "Recorded in Amendment 4" and now pointed at two of them. It becomes Amendment 5, takes the file's own `##` heading shape, and every carrier that named the wrong number follows: Database Standards, the delivery record, the schema test and the migration's remarks. The Status header listed Amendments 1-3 only, so a reader following the authority metadata could not tell either Amendment 4 or 5 was part of the record. Both are named now. Every_Write_Port_Is_Countable_Or_Enumerated claimed to find interfaces taking a domain type and checked the parameter's own assembly, so IEnumerable<Course> answered System.Private.CoreLib and escaped — which is how a bulk write port is written. It unwraps generic arguments, array elements and by-ref transitively now, the same shape the IEventBus rule uses, and a probe bulk port is caught. Out_Of_Band_Setters_Open_Read_Only_Transactions is a source scan that orders SET TRANSACTION against the first set_config, and the catalogue described it as ordering against the first statement. PostgreSQL refuses SET TRANSACTION after any statement, so a setter that ran a SELECT in between would satisfy the rule and fail at runtime. The entry now says what the comparison measures and what it therefore does not catch — loudly, since that failure is immediate rather than silent, and parsing every command execution is the expensive alternative.

Summary
from the pull request's own review rounds, and the sharpest defect of the packet was
among them — a record that stopped before them would be a false account.
05-database.mdcarries a template ADR-0003 Amendment 4 corrects, and did not name it.Documentation only. No source, no tests, no schema.
Approach
The record now carries § What the pull-request review found, in the same spirit as the
rest of it — what the packet got wrong, not only what it shipped:
PromoteDefaultclears then sets in memory, EFdoes not preserve that order, and this packet's own PR description cited that
invariant as the migration's safety rationale.
tenant-wide rows — corrected in the template, because every organization-scoped table is
told to copy it.
test, three ADR edits made outside the rules that govern them.
process works: MediatR already deduplicates pipeline behaviours, so a guard written for
it was removed rather than shipped; and the query filter's pinned
DbContextis harmlessbecause its
CurrentTenantIddelegates to the process-wide accessor.The measured total moves to 1208, counted from a run.
§ What it did not ship gains the two idempotency limits that do not bound memory and
the two-migrations-in-one-PR deviation, each with its owner and the measurement behind it.
Tests
CI=true dotnet test backend/LearnStack.slnx— 1208 green (1 contract, 79architecture, 813 unit, 315 integration), unchanged by this PR, which touches no code.
Relative-link audit and
docs/analysis/residual scan both clean over the changed files.Migration / Rollback
None. No schema, config or data change.
