 ### Data and correctness
 
+- **Business dates, row timestamps and list sequences are separate facts (#819).** Keep farm operational dates as `DateOnly`. Every mapped business record except the explicitly excluded `AuditEvent` carries a PostgreSQL-stamped `DateTimeOffset CreatedAtUtc`; a record that supports an in-place update also carries `DateTimeOffset UpdatedAtUtc`, set equal to creation time on insert and replaced on each update. Factories and handlers never stamp these generic fields. A chronological list orders by business date, `CreatedAtUtc`, then a shadow per-table `bigint GENERATED ALWAYS AS IDENTITY` `Sequence`, all in the list's direction; a list with no business date omits that key. `Sequence` resolves equal timestamps and completes the order for a fixed dataset; it does not repair clock rollback or make offset pagination snapshot-stable across concurrent inserts. Give `Sequence` a database uniqueness constraint and never expose it through domain objects, responses, exports or screens. Name-ordered lookup lists and canonical FIFO or `FOR UPDATE` ordering do not gain a sequence. Classify every new mapped table through `ICreatedRecord`, `IMutableRecord` or an explicit framework or infrastructure exclusion, and add it to the chronological census only when users page or read it by time. Preserve action-specific timestamps and `Version`. Legacy audit backfills use only exact whitelisted row events and fall back to the documented unknown sentinel. → [`819-business-record-chronology.md`](docs/decisions/819-business-record-chronology.md)
+
 - **Every aggregate mutation must bump `Version`.** `Version` is an EF concurrency token (`IsConcurrencyToken`): EF puts the *original* value in the UPDATE's `WHERE` but never auto-increments it, so a mutation without `Version++` silently loses concurrent races — both writers match `WHERE Version = N` — instead of 409ing. This shipped three times; each fix carries a parallel-race integration test, and so must any new mutation.
 - **Multi-tenancy:** every tenant-owned entity has `AccountId`, enforced by an EF **global query filter** plus a **`TenantStampInterceptor`** (stamps on insert, and rejects a mismatched write on update/delete). `TenantContext` resolves per-request from the JWT `account_id` claim and is **single-assignment** — a differing re-resolve throws; at startup it is unresolved, so seeders use `IgnoreQueryFilters()`. Several farms now coexist on one deployment: sign-in takes a farm code, and one email address can belong to a user in more than one farm. **`AccountId` is also an EF concurrency token on every entity that carries one (#562):** the `UPDATE`/`DELETE` the database runs carries `AccountId = <original>`, so a detached stub aimed at another farm's row matches nothing — the interceptor alone cannot see a detached write, and an owned-only edit on an attached stub was writing through until the token landed. The token comes from a model walk in `AppDbContext.OnModelCreating`, so a new entity is covered automatically; never remove it, and a database refusal under a resolved tenant is logged as `Tenant.WriteRefusedByDatabase`. **`AccountId` must be a non-nullable `Guid`, and both layers now fail closed on anything else (#673):** the walk throws `TenantAccountIdShapeException` at model build for any other CLR type and the interceptor throws it at `SaveChanges` for a mapped type that is not `Guid` or a value that does not box to one — before, a `Guid?` or a strongly-typed id got no token and no check, which is #562's detached-write hole reopened by one mapping with every test green. Map a new tenant-owned entity's `AccountId` as a plain `Guid`; a strongly-typed id there needs this decision reopened, not a cast. **Identity's `AspNetUserRoles` carries a shadow `AccountId` plus a composite foreign key to `AspNetUsers(Id, AccountId)` (#670):** both layers select by property NAME, so the shadow column is stamped, verified and tokened like any other, and the FK makes a role grant to another farm's user — or under no resolved tenant — a database refusal; the other four user-keyed Identity tables have no writer in `src/` and are recorded as accepted risk. → [`530-multi-farm-tenancy.md`](docs/decisions/530-multi-farm-tenancy.md)
 - **A farm code changes only through `Account.Rename`, reached by the `rename-account` verb (#732).** No endpoint, no Settings field, and never a raw `UPDATE` — the hand-guarded `UPDATE "Accounts"` that preceded it bumped `Version` by hand, wrote no audit row and checked neither the slug pattern nor the reserved set. `Rename` validates through the same `TryValidateSlug` provisioning uses, bumps `Version` on a real change and deliberately does **not** bump it on a no-op (a rename to the code the farm already has mutates nothing, so "every mutation bumps `Version`" still holds and a Farm Settings form held open does not break). The service resolves the code to an id, resolves the tenant, takes the tenant-keyed `FOR UPDATE`, and then **re-compares the locked row against the snapshot the lookup took — both its slug and its `Version`** — lookup and lock are two statements, so a write that committed in between would otherwise be silently overwritten. Neither half of that comparison is redundant: `Version` catches the ABA schedule (renamed away and back, so the code the lookup read is the code the lock finds), the slug comparison catches a code change that never advanced `Version` (a raw `UPDATE`), and the price is that a rename racing a Farm Settings save or a suspend also returns `Account.SlugStale`. `IX_Accounts_Slug` and the `DbUpdateException` catch are the authority on the destination code; the pre-read in front of them is convenience. There is **no retired-code list**: a code a farm has moved off is immediately reusable, so `--slug <retired>` targets whoever holds it now — an accepted cost, which is why the verb and the runbook both say to run `list-accounts` immediately first. → [`732-farm-code-rename.md`](docs/decisions/732-farm-code-rename.md)

+# Business dates, row timestamps, and list sequences are separate facts (#819)
+
+## What happened
+
+Several lists ordered rows by a farm business date and then by a random UUID.
+Rows from the same day therefore had a stable but arbitrary order. A recent row
+could appear below older rows or beyond the first page. The first change added a
+database identity sequence to five lists. A full model walk found six more
+chronological lists and showed that most business tables also lacked consistent
+creation and update metadata.
+
+## The rule
+
+Farm business dates remain `DateOnly`. They describe the day on which farm work
+belongs. `CreatedAtUtc` and `UpdatedAtUtc` describe database writes. Every mapped
+business record except `AuditEvent` implements `ICreatedRecord`. A record that
+supports an in-place update implements `IMutableRecord`. PostgreSQL stamps both
+fields with `timestamp with time zone` values. On insert, mutable rows receive
+the same value for both fields. On update, PostgreSQL preserves `CreatedAtUtc`
+and replaces `UpdatedAtUtc`.
+
+The business-record census includes the 25 domain record types other than
+`AuditEvent`, plus `ApplicationUser`. `AuditEvent` keeps its established
+`OccurredAtUtc` meaning. ASP.NET Identity support types, including passkey data,
+and the operational refresh-token, idempotency, durable-job, and simulation-seed
+tables retain their own lifecycle fields and do not join this convention.
+
+Eleven chronological tables also carry a shadow `bigint GENERATED ALWAYS AS
+IDENTITY` property named `Sequence`: `SalesOrders`, `Expenses`, `DailyEntries`,
+`EggLots`, `BirdMovements`, `Payments`, `InventoryLots`, `FeedUsages`,
+`WaterUsages`, `InventoryMovements`, and `EggInventoryMovements`. Each table has
+a unique constraint on `Sequence`. Interactive lists with a business date order
+by business date, creation time, and sequence, all descending.
+`EggInventoryMovements` has no independent business date and orders by creation
+time and sequence. The sequence stays outside domain objects, API responses,
+exports, and screens.
+
+The generic timestamps are persistence metadata in this change. Existing API
+and CSV fields stay compatible; a later contract change can expose the new
+timestamps where a user needs them. Datasets that already exported a creation
+timestamp continue to do so.
+
+Exports keep their established direction but use the same complete tuple in
+that direction. FIFO selection and `FOR UPDATE` lock acquisition keep their
+existing business-date and UUID order because those queries define allocation
+behavior and canonical lock order rather than presentation chronology.
+The flock export also keeps its established `PlacementDate, Id` order: flock
+screens are name-ordered, so flocks are not a chronological paged list and do
+not gain a persistence sequence solely for export formatting.
+
+## Existing rows
+
+The migration preserves every stored `CreatedAtUtc`. For a table that did not
+store it, the migration uses the earliest exact creation audit whose
+`EntityType`, `EntityId`, and action match a frozen table-specific whitelist.
+If no such event exists, it uses `1970-01-01T00:00:00Z` as an explicit unknown
+sentinel. The sentinel is not a recovered historical time.
+Fresh databases replay the same migration history, so base reference rows that
+predate this migration also receive the sentinel; it means unknown there too,
+not that those records were created in 1970.
+
+For mutable rows, the migration uses the latest exact mutating audit from a
+frozen table-specific whitelist. It ignores read-only actions and events aimed
+at a parent record. If no qualifying update exists, `UpdatedAtUtc` equals
+`CreatedAtUtc`. The migration never infers a write time from a business date or
+a UUID.
+
+Legacy sequence values provide deterministic order only. They cannot recover
+the original insertion order. For new rows, PostgreSQL allocates `Sequence` at
+insert time, not commit time. A transaction that commits later may have a lower
+sequence than a transaction that commits earlier. Neither a timestamp nor an
+identity sequence claims exact commit chronology.
+
+`CreatedAtUtc` deliberately precedes `Sequence` in the agreed display tuple.
+The sequence therefore resolves equal timestamps; it does not repair a system
+clock that moves backwards. Offset pagination has a complete order for a fixed
+dataset, but concurrent inserts can still move rows between pages. Cursor or
+snapshot pagination would be a separate contract.
+
+## Why PostgreSQL owns the timestamps
+
+EF interceptors do not see `ExecuteUpdateAsync` or raw SQL. Cluckwork uses both,
+and an owned-value update can also change a database row without presenting the
+same tracked shape as an ordinary aggregate edit. PostgreSQL triggers cover all
+of these write paths. Read-only interfaces expose the metadata without giving
+handlers or factories another stamping path.
+
+Action-specific fields remain separate. `OccurredAtUtc`, `LockedAtUtc`,
+`ReleasedOnUtc`, `DisabledAt`, `FarmLogo.UpdatedAt`, and
+`FarmLogo.BannerUpdatedAt` keep their existing meanings. Generic timestamps do
+not replace audit history, domain event times, or optimistic `Version` tokens.
+
+## Migration and enforcement
+
+The unmerged sequence migration is replaced by one chronology migration. The
+migration adds and backfills columns before it installs triggers. It takes table
+locks and runs through the pre-deploy migration process. Schema documentation
+is regenerated from the final model.
+
+The migration begins with a five-second `lock_timeout`. That limits how long it
+waits to acquire a lock, not how long acquired locks remain held; the migration
+transaction retains them until commit. CI proves the upgrade on its fixture,
+not its duration at production volume, so deployment must time it on a
+production-sized copy before running the pre-deploy job.
+
+An executable model census classifies every mapped type as mutable,
+create-only, or excluded. It also fixes the set of chronological tables. A new
+mapped type cannot rely on a developer remembering this document alone.
