test(arch): module ledger and cross-owner edge ratchet (#842)

[mforce]

Closes #842

Slice 1 of #514 (modular monolith), Track A. Enforcement only. No src/ file, no CI change, no package, no move.

What this adds

• tests/Cluckwork.Application.Tests/Architecture/Data/module-ledger.json — nine owners by namespace, and every cross-owner edge between the eight business modules as a cell (from, to, kind, reason) listing the top-level types that realise it. 16 cells, 66 symbols, symbol lists produced from the guard's own failure output (it prints the JSON to paste for every undeclared edge), reasons written by reading each referencing file.
• Architecture/ModuleLedgerScanner.cs — a syntax-only Roslyn walk over every .cs under src/, riding GuardScanner's root and enumeration helpers. Reports undeclared edges (with the JSON to paste), stale rows, unowned namespaces, parse errors, registry errors, and a file-count floor.
• Architecture/ModuleLedgerTests.cs — temp-tree tests, one named assertion per failure class.
• Architecture/ModuleLedgerRealTreeTests.cs — the gate.
• docs/decisions/514-module-ledger.md and one AGENTS.md paragraph under Application shape.

What the walk found that the design's matrix does not say

§3.4 marks five cells as no coupling that are live in source: Farm → Commerce, Access → Commerce, Commerce → Access (the three the re-plan named, all from #727), plus GeneralInventory → EggOperations (feed and water usage inject IDailyEntryRepository) and Access → EggOperations (provisioning seeds default egg grades). All five are ledgered with reasons; none is a defect, and this PR changes no behaviour.

Keyed by owner and top-level type, never namespace or file:line

Customer.cs living under Domain/Sales/ is not an edge because both ends are Commerce. A file-level using pins to every top-level type in the file. Platform (Api.*, Infrastructure.* except Identity, Domain.Common, Domain.Auditing, Application.Common) is the free hub, per §3.4; narrowing it is Track B.

Mutation evidence (each recorded red, then reverted before commit)

#	Mutation	Red line
1	using Cluckwork.Application.Features.Catalog; added to Flocks/CreateFlock/CreateFlockHandler.cs	undeclared cross-owner edge FlockManagement -> Commerce from Cluckwork.Application.Features.Flocks.CreateFlock.CreateFlockHandler (references Cluckwork.Application.Features.Catalog) at src/Cluckwork.Application/Features/Flocks/CreateFlock/CreateFlockHandler.cs:4
2	Farm → Commerce cell deleted from the ledger	undeclared cross-owner edge Farm -> Commerce from Cluckwork.Application.Features.Accounts.UpdateFarmSettings.UpdateFarmSettingsHandler … plus the validator and Cluckwork.Domain.Accounts.Account
3	Cluckwork.Application.Features.Expenses.CreateExpense.NoSuchHandler added to the Finance → Farm cell	stale ledger row Finance -> Farm :: Cluckwork.Application.Features.Expenses.CreateExpense.NoSuchHandler — no reference in src/ realises this edge
4	RealTreeFileFloor raised to 500	scanned 466 files, expected at least 500 — the walk saw less than it should (also reds RealSourceTree_FloorIsTheStaticMinimumNotTheScannedCount)
5	src/Cluckwork.Domain/Foo/Foo.cs added with namespace Cluckwork.Domain.Foo;	unowned namespace 'Cluckwork.Domain.Foo' declared in src/Cluckwork.Domain/Foo/Foo.cs — every namespace in src/ must be claimed by exactly one ledger owner

Mutation 5 is the reason Platform claims Cluckwork.Domain and Cluckwork.Application through exactNamespaces rather than as subtrees: a subtree claim would absorb a new module namespace silently. Full outputs are attached below.

Verification

• dotnet build Cluckwork.sln: 0 warnings.
• Cluckwork.Application.Tests: 316 passed (25 in Architecture/), Cluckwork.Domain.Tests: 491 passed.
• Documentation tests (19) and SchemaDocsTests (4) green on the new markdown.
• The five mutation runs above, each reverted before commit; the real-tree gate is green on the clean tree.

📝 Walkthrough

Walkthrough

The change documents a module ledger, records current ownership and dependency edges, scans C# source with Roslyn, and adds architecture tests for undeclared edges, stale entries, ownership errors, platform exemptions, and real-tree coverage.

Changes

Module ledger enforcement

Layer / File(s)	Summary
Ledger convention and decision record AGENTS.md, docs/decisions/514-module-ledger.md, docs/decisions/README.md	Documents the ledger rule, ownership and dependency semantics, Platform exemptions, enforcement scope, and decision-record index entry.
Ledger data and validation tests/Cluckwork.Application.Tests/Architecture/Data/module-ledger.json, tests/Cluckwork.Application.Tests/Architecture/ModuleLedger.cs, tests/Cluckwork.Application.Tests/Cluckwork.Application.Tests.csproj	Defines nine owners and their dependency edges. Adds JSON loading and validation for owners and edges. Copies the ledger to test output.
Source-tree scanning and evaluation tests/Cluckwork.Application.Tests/Architecture/ModuleLedgerScanner.cs	Scans C# files with Roslyn, resolves namespace ownership, detects cross-owner references, identifies undeclared and stale entries, and creates failure messages.
Architecture and mutation coverage tests/Cluckwork.Application.Tests/Architecture/ModuleLedgerTests.cs, tests/Cluckwork.Application.Tests/Architecture/ModuleLedgerRealTreeTests.cs	Tests ledger mutations, namespace resolution, platform handling, parse and registry errors, stale rows, and real-tree file-count enforcement.

Local Codex review round (CodeRabbit was rate-limited between rounds; owner rule is to substitute a local Codex review). Nine findings, all confirmed against the code and fixed in 36e2870, each with a temp-tree regression test:

1. Relative qualified references (Domain.Sales.Customer from inside Cluckwork.Application.Features.Flocks) were dropped for lacking the Cluckwork. prefix; now resolved against each enclosing-namespace prefix, longest first, and only accepted when the match is deeper than the file's own prefix (so BCL names never produce an edge).
2. Compound using aliases (using X = List<Cluckwork.Domain.Sales.Customer>;) hid their generic arguments; every outermost dotted name inside a directive is now recorded.
3. global using of a module namespace hides simple-name dependencies from a syntax walk; now a failure in its own right (same as CodeRabbit's round 2 finding).
4. Generic arity was missing from symbol keys, so Foo and Foo<T> shared one row; type parameters are now part of the key. No committed symbol changed.
5. A second block namespace's declaration name was recorded as a reference and attributed to the first type; names inside a namespace declaration are now skipped.
6. An exact claim rejected a reference to a type declared directly in that namespace (Cluckwork.Domain.RootType); exact claims are now strict for a declared namespace only, and resolve like a subtree for a referenced name. Sound because every referenced Cluckwork.* namespace is also declared in src/, where the strict check still fires.
7. Parsing ignored preprocessor symbols; the walk now parses with the net10.0 symbol set. src/ has zero #if today.
8. Access → Farm is W (AccountProvisioner inserts the Account, AccountRenameService renames and saves), not R.
9. The Access → Commerce reason claimed a guarantee the code does not give and misdescribed the validator; rewritten to what the code does.

Verification: Cluckwork.Application.Tests 324/324 (33 in Architecture/), build 0 warnings, PR mutation 1 re-run red (/tmp output in the next round's evidence). Codex's output: 9 findings, no dismissals.

Local Codex review, round 2 on 36e2870 (CodeRabbit round 3 was rate-limited). Three findings, all confirmed and fixed in eb60c89, each with a regression test:

1. Two file-local types with the same name in one namespace collapsed onto one symbol, so one row could excuse the other; a file-local type now carries its file path in its key (Namespace.Probe@src/…/One.cs).
2. The parse defined the target-framework symbols but not DEBUG/TRACE, which the test build defines; a reference inside #if DEBUG was invisible. Both symbols are now defined.
3. Generic keys carried type-parameter names, so renaming Probe<T> to Probe<TItem> produced a stale row plus an undeclared edge; keys now carry arity only (Probe<>, Probe<,>).

Verification: Cluckwork.Application.Tests 326/326, no committed ledger symbol changed.

Local Codex review, round 3 on eb60c89. One finding, rated low-likelihood by the reviewer: the 400-file floor cannot prove the walk saw every file, so a traversal regression that skipped one new directory would stay green.

Dismissed, with the reason. The floor is the same accepted pattern as GuardScanner.RealTreeFileFloor (#536), the enumeration is shared with that guard (a recursive walk that skips bin/obj), and an independent enumeration would add a git dependency to the test to catch a regression in a ten-line walker. If the walker ever grows path filters, that is the moment to add a second enumeration.

Stopping the local review loop here, deliberately. CodeRabbit round 1: 2 confirmed; Codex round 1: 9 confirmed; CodeRabbit round 2: 1 confirmed; Codex round 2: 3 confirmed; Codex round 3: 1 dismissed. CodeRabbit's own next round still lands when its window resets and will be handled.

CI note: the integration leg on eb60c89 failed once on MultiInstanceRateLimitTests.Login_budget_is_shared_across_two_instances_over_one_redis (expected 429, got 401), the flake tracked in #840; this PR changes nothing the integration project references. Re-run of the failed job is green (15 pass, 1 skipped). Occurrence recorded on #840.

Codex (gpt-5.6-sol) review of record on 51369ed, in lieu of the CodeRabbit bot per the owner's decision: every earlier fix verified present; two new findings, both confirmed and fixed in e18da43 with regression tests:

1. global using D = Cluckwork.Domain; (an alias to an exactly claimed Platform root) was accepted although D.Sales.Customer at a use site cannot be expanded by a syntax walk; a global alias whose target is an exact root namespace is now a failure like a global import of a module namespace.
2. A single-identifier relative import (using Sales; inside Cluckwork.Application.Features.Flocks) was skipped by the directive walk; it now joins the dotted names and resolves relative to the enclosing namespace.

Verification: Cluckwork.Application.Tests 329/329, build 0 warnings. Re-review requested on e18da43.

[mforce]

Codex (sol) re-review on e18da43: both fixes verified complete; one regression found, that a single-identifier alias target (using Alias = Blue;) naming a local type was read as a namespace import. Fixed in f975dfb: the single-identifier case now applies to non-alias directives only, with SingleIdentifierAliasToALocalType_IsNotAnEdge. Verification: Cluckwork.Application.Tests 330/330. Re-review requested on f975dfb.

[mforce]

Codex (gpt-5.6-sol) round 3 on f975dfb: the alias regression is fixed, no new finding. VERDICT: approve, 0 findings. Reports kept at /tmp/514/codex-sol-872*.md on the build machine.

Reviewer-side summary of this PR: CodeRabbit 4 rounds (4 confirmed findings), Codex 3 rounds (13 confirmed, 1 dismissed with reason), sol 3 rounds (2 confirmed, 1 regression fixed). Ready to merge: closes #842, CI green on the previous head 51369ed and re-running on f975dfb, on the Modular monolith milestone. #877, #878 and #879 stack on it and retarget after the merge.
