feat: certify over-cap simulation fixture bands

[mforce]

Closes #627

What

The simulation fixture now holds more than one page on the three paged
surfaces a farm user actually walks, and the seeder's completion manifest
certifies the bands EXACTLY (fail-closed) instead of as floors.

Exact counts (default 90-day history)

Band	Count	Detail
Customers	101	3 lifecycle + 97 Sim Customer Filler 001..097 + Sim Customer Z Page Two (lexically last)
Flocks	102	2 operational Active + 97 Sim Z Flock Catalog 001..097 + Sim Z Flock Page Two + Sim Z Flock Depleted + Sim Z Flock Archived = 100 Active / 1 Depleted / 1 Archived
Bird movements	87 (default) / 55 (12-day test)	automatic mortality baseline + 51 explicit adjustments on Sim House A
Inventory movements	122 account-wide	120 on the feed item (10 pre-existing + 110-row +1 adjustment band) + 2 on the bedding item

Automatic-mortality formula (explicit day loop, never division): one
row per (operational flock, day) where d % 5 == 0 for
d in DraftWindowDays+1..historyDays — 18 per flock at 90 days (36
account-wide), 2 per flock at 12 days (4 account-wide).

Key invariants

• INV-3 — only the two original topology flock ids enter the
  daily/feed/water/expense fanout; the catalog rows are created in a
  separate phase and are certified fanout-free by SetEquals against the
  operational id set.
• Picker ordering (driver-locked naming) — every catalog row sorts
  AFTER both operational houses ("Sim Z …" > "Sim House …"), so the two
  houses stay inside the first 100 rows of the default-limit BY NAME
  picker; with the 101 non-archived rows, page one = both houses + 98
  earliest catalog rows, and only the sentinel Sim Z Flock Page Two
  sits alone on page two. A new integration assertion certifies this
  through the repository's own query path (Postgres ordering, non-archived,
  OrderBy Name ThenBy Id, Take(100) / Skip(100)).
• Natural keys, never free text — bird movements (FlockId, Date),
  inventory adjustments (InventoryLotId, Date).
• Adjustment-band order — the 110 +1 rows run AFTER the 8 feed usages
  (−144 kg) and the discard (−15 kg), because InventoryLot.Adjust
  refuses a correction that would leave the lot at/above its received
  quantity; the band then lands at 2951 < 3000.
• Manifest schema 2 — gains Customers, BirdMovements counts and
  the Flocks lifecycle split, with exact checks, a flock-state
  reconciliation sum, and states.Flocks folded into the fingerprint
  canonical object (the deliberate daily-entry-state exclusion is kept).

E2E

New tools/simulation/ui/specs/pagination.spec.ts: three independent
Load-more tests (customers / bird-movement ledger / feed-item ledger),
each proving the sentinel is absent before, clicking the surface's
translated Load-more exactly once, then asserting the sentinel row
with its fixture detail (555-0299; −1 + translated Adjustment;
+1 kg + translated Adjustment).

Caller inventory (write/read contract audit)

• k6: listCustomers/listFlocks calls use limit=500 where they list
  (dashboard/history bundles) — no count assumptions below 101/102.
• SPA: paged surfaces (CustomersPage 100/page, ledgers 50/100) page
  server-side; DailyEntryPage picker takes the default 100, now
  guaranteed to contain both operational houses by the ordering invariant.
• Playwright: worker.spec.ts Worker flock assignment is enforced on writes but not on reads — a restricted worker can enumerate and read unassigned flocks #388 tests (unchanged) pass because the
  operational houses stay in the picker; manager.spec.ts,
  sales.spec.ts self-create their fixtures and are count-agnostic.
• Seeders read handlers, not counts — the only count consumers are the
  three manifest test files, all updated in this PR.

Mutation ledger (all restored; git diff --check clean)

ID	Mutant	Product proof	UI leg
M1	sentinel customer name → existing filler name	manifest RED customers: expected 101, got 100	conclusive RED (absent-before/one-click flow)
M2	bird sentinel date → d=1 (occupied)	manifest RED expected 55, got 54	inconclusive/preflight-blocked (fail-closed seed refused before browser); separate nonexistent-literal spec mutation reached the one-click flow and failed present-after
M3	feed sentinel date → opening+2 (discard-owned) — attempt 1 ?1:d was a no-op (counted failed attempt); attempt 2 ?2:d	manifest RED feed 119 / account-wide 121	inconclusive/preflight-blocked; separate nonexistent-literal spec mutation failed present-after
M4	sentinel flock name → existing catalog name	manifest RED flocks 102/101, active 100/99	product-only per ledger
M5	bird equality → < (short count passes)	synthetic short-bird test RED	n/a
M6	fingerprint states.Flocks → new SimulationFlockStates(0,0,0)	flock-lifecycle fingerprint test RED (hashes equal)	n/a

Base differentiation: the current spec run against the exact base
(062a55c) stack failed 3/3 on the Load-more/sentinel assertions —
recorded as a historical base RED, not test-first evidence (the C#
implementation predates any RED).

Baseline flakes

None observed on this head. Baseline-known flakes for the record:
ExpensesPage (#557/#563) and CustomersPage (#625) 5-second timeouts on
exact-base CI; owner previously approved proceeding.

#512 retains the picker implementation/E2E; this PR certifies the fixture
bands that picker pages through and does not touch picker behaviour.

📝 Walkthrough

Walkthrough

The simulation seeder now creates expanded customer, flock, bird-movement, and inventory fixtures. Manifest counts and fingerprints include the new data. Integration and Playwright tests verify exact counts, rerun stability, operational fanout, lifecycle states, and pagination.

Changes

Simulation fixture expansion

Layer / File(s)	Summary
Expanded simulation fixture data src/Cluckwork.Infrastructure/Persistence/SimulationDataSeeder.cs	The seeder adds 101 customers, 102 flocks with lifecycle states, explicit bird movements, and a 110-row feed-adjustment band. Production fanout remains limited to two operational flocks.
Manifest counts and fingerprint contracts src/Cluckwork.Infrastructure/Persistence/SimulationDataSeeder.cs	Manifest schema version 2 includes customer, bird-movement, flock lifecycle, and expanded inventory counts. Validation and fingerprint generation cover the new fields.
Seeder and rerun validation tests/Cluckwork.Api.IntegrationTests/SimulationCrossDayRerunTests.cs, tests/Cluckwork.Api.IntegrationTests/SimulationSeedCommandTests.cs, tests/Cluckwork.Api.IntegrationTests/SimulationSeederTests.cs	Tests verify exact fixture bands, idempotent reruns, operational-flock fanout, lifecycle fingerprints, validation failures, and cross-day duplicate detection.
Over-cap pagination scenarios tools/simulation/ui/specs/pagination.spec.ts	Playwright tests verify customer, bird-movement, and feed-item sentinels after one Load-more action.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to f47c1

The change expands and certifies simulation fixture pagination bands without introducing an actionable merge-blocking product risk. It is merge-ready after normal checks, with only localized maintainability and test-fidelity follow-up remaining.

1927-1941: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Derive the expected-count constants from the seeding constants.

ExplicitBirdMovementsCount duplicates ExplicitBirdMovementCount (line 905), FeedAdjustmentBandCount duplicates FeedAdjustmentCount (line 1535), and CatalogFlockBandCount must always equal NumberedCatalogFlockCount + 3. The names differ by one letter, so an edit to one side alone compiles and then fails the seed at ValidateCounts. Bind each expected value to the value the seeder actually uses.

Call the flock list path instead of duplicating its query.

IFlockRepository.ListAsync defines the default filter, ordering, and pagination. Depleted flocks remain visible; only archived flocks are excluded. This test queries db.Flocks directly, so it will not detect changes to the production flock list path. Use IFlockRepository.ListAsync or the list endpoint for these assertions.
