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.Flocksnew 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.

…counts

#627 — the simulation fixture now holds more than one page on the three
surfaces a farm user walks, and the manifest certifies the exact bands
instead of a floor:

- 101 customers (3 lifecycle + 97 fillers + lexically-last sentinel)
- 102 flocks split 100 Active / 1 Depleted / 1 Archived; the 100-row
  picker catalog sorts AFTER the two operational houses ("Sim Z …") so
  the houses stay inside the first 100 BY NAME picker rows and the
  sentinel sits alone on page two
- 55 bird movements: the automatic-mortality baseline (an explicit day
  loop, 2 per flock on the 12-day test fixture) plus 51 explicit
  adjustments on Sim House A, natural-keyed (FlockId, Date)
- 122 inventory movements account-wide: exactly 120 on the feed item
  (10 pre-existing + a 110-row +1 adjustment band natural-keyed
  (InventoryLotId, Date), seeded AFTER the usages/discard so the lot is
  drawn below its received quantity first) and 2 on the bedding item

Manifest schema 2: adds Customers/BirdMovements counts and the Flocks
lifecycle split, with exact fail-closed checks, a flock-state
reconciliation sum, and states.Flocks folded into the fingerprint.

Also re-points the two pre-existing db.Roles line numbers in the
tenant-bypass filter-free-set baseline (mechanical, owner-approved).

Closes #627
#627 — three independent Load-more acceptance tests against the certified
fixture: the customer book's page-two sentinel customer, Sim House A's
bird-movement ledger sentinel (quantity rendered in the flock ledger's
Unicode minus form), and the feed item's movement-ledger sentinel
("+1 kg"). Each proves the sentinel is absent on the first page, clicks
the surface's translated Load-more exactly once, then asserts the
sentinel row with its fixture detail. The absence-before-click assertion
is load-bearing: a sentinel on page one means the page size, ordering, or
the seeder's counts drifted.

Closes #627

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.
