Rewrites prose in docs/architecture.md that read as padding or jargon, and removes counts copied from code that had gone stale. Every diagram is unchanged, and so is the guard CouplingMatrixRealTreeTests.RealTree_FeatureModuleDiagramNamesExactlyTheLedgerOwners.

Follows #1098, whose code and prose were never cleaned up.

What changed

• Request pipeline intro. The old text said the full list "runs to 30 entries (22 Use* registrations, seven terminal/map registrations, and app.Run())". Program.cs on main has 22 app.Use* calls but far more than seven map lines. The new text says the diagram shows only the steps whose order matters and points to Program.cs for the full list.
• Lock sweep cutoff. The prose named the constant LockAfterDays in place of a copied "7". The diagram label still reads "7 days", because the diagrams are unchanged.
• Wording. I replaced em-dash asides, parentheses, "load-bearing", "decisions, not accidents", "in its own right", "is real — but" and "The mechanism is ready; the writer is not" with plain sentences. I also moved passive phrasings ("are drawn", "are refused by the browser", "is covered by") to the active voice.
• Feature modules. "(Farm also declares a small seam)" is now its own sentence: other modules, never endpoints, may also use Farm's seam.

Untouched: the four diagrams; the two table rows changed in #1124; the guard, which deslop found clean.

Claims checked against code

Claim kept	Where
Lock cutoff is a named constant	DailyEntryLockSweep.LockAfterDays = 7
Flock scope skips a /error re-execution	FlockScopeResolutionMiddleware.cs, IExceptionHandlerFeature check
No production path writes RestrictedUntil	SetWithdrawalRestriction is called only from tests
The simulation seeder asserts Shipped and Invoiced stay zero	SimulationDataSeeder.cs, two Check(... == 0) lines

Proof

• Guard still fails. I deleted the Finance node from the feature-modules diagram, and the guard turned red: Assert.Equal() Failure: Collections differ, with "Finance" expected but missing. I restored the file before committing.
• Doc guards at the head. CouplingMatrixRealTreeTests and TenancyDocsFreshnessTests pass 4/4. The SchemaDocsTests image-pin guards pass 2/2.
