Version every /api route to /api/v1 (251 controller routes + ~24 Location
headers + the scanner callback URL + the Startup request-log literal),
uniform across the machine API, auth, scanner and scripted-build surfaces.
Add ApiVersionRewriteMiddleware: a legacy unversioned /api/* request is
rewritten (NOT redirected) to /api/v1/* in-pipeline — method, body, auth
headers and query survive — carrying RFC 8594 Deprecation/Sunset headers,
so curl / the future MCP server / bookmarks keep working. An already-
versioned path passes through; a future /api/v2 is never forced to v1.
Standardize the route convention (leading-slash absolute route per method,
no class-[Route] — except the two Scanner/Scripted controllers whose ~all
actions share a parametrized {id} prefix), enforced by ApiRouteVersioningTests
(^/api/v\d+/ over the whole Controllers.Api surface; browser-nav
/auth/oidc/login is out of scope).
Regenerate v1.json (160 paths, all /api/v1)/endpoint-index/v1.d.ts; sweep 945
SPA request literals + the test mocks (regex + positional URL parsers). /api/v1
is additive-only after freeze; the legacy-rewrite shim sunsets in ~2 releases
(owner decision) with removal tracked as a Phase-3 follow-up.

The shared optimistic-concurrency parser (ConcurrencyHeaders.ParseIfMatch) classified any
non-canonical/weak/list If-Match value as Malformed → 400. Per RFC 7232 §3.1 a syntactically
-valid entity-tag that simply doesn't strong-match must be 412; 400 is only for a genuine
grammar violation.
- Rewrite ParseIfMatch as a real RFC 7232 entity-tag/list parser: walks the comma-separated
1#entity-tag list, validates each [W/]DQUOTE *etagc DQUOTE member, and collects the strong
members whose opaque text is our canonical decimal. Weak / empty / non-canonical /
out-of-range tags are valid but contribute no version (→ empty set → 412); genuine grammar
violations (unquoted, SP-in-tag, unterminated, garbage) → 400.
- Reshape IfMatchCondition.ExpectedVersion : Option<int> → ExpectedVersions : Option<Seq<int>>
and VersionedAggregateExtensions.CheckVersion → set membership (any strong match proceeds;
empty set always 412). Threads through 10 replace/update commands + handlers + request
mappers + 9 controllers.
- No wire-contract change (400 + 412 already declared on every PUT; the field is header-derived
and internal — no DTO/route/response-type/OpenAPI change).
- Tests: ConcurrencyHeadersTests rewritten for the new classification (lists, weak, empty,
non-canonical → Version/empty-set; grammar violations → Malformed) + new
VersionedAggregateExtensionsTests for CheckVersion membership/empty-set/force-write.
- Docs: api-conventions.md §7a rewritten; decisions.md entry appended.

Adds the shared optimistic-concurrency contract so a stale second tab can no longer
silently overwrite a fresher edit. PR1 lands the infra + the Block reference aggregate;
PRs 2–4 fan the same recipe across the other 8 roots (design: #253#issuecomment-8472).
Contract
- `IVersionedAggregate` (`int Version`) on all 9 replace-all roots (ProgramSchedule,
Block, Template, DecoTemplate, Playlist, Collection, Playout, MultiCollection,
RerunCollection), EF-mapped `.IsConcurrencyToken()`; one dual-provider migration
`AddAggregateVersions` (nullable:false, default 0).
- Strong `ETag` of `Version` on the aggregate GET; `If-Match` on the PUT; mismatch →
412 (distinct from the §3a 409 build-lock guard). Successful PUT returns the new ETag.
- `PreconditionFailedError : BaseError` → 412 in `ApiResults.ToErrorResult`;
`ConcurrencyHeaders.ParseIfMatch/SetETag`; malformed If-Match → 400; `*`/absent =
Phase-1 force-write.
Block reference wiring
- Handler: standalone `Either` via `CheckVersion` AFTER validation (never through
`Apply`, which Join()-flattens the subtype to 422), unconditional `Version++`,
`SaveChangesWithConcurrencyGuard` backstop (DbUpdateConcurrencyException → 412).
- `BlockViewModel.Version` (header-only, not echoed in the body); controller sets the
ETag on GET items and on the successful PUT.
- SPA: `client.requestWithMeta` seam; `blocks.getBlockItemsWithMeta` + `replaceBlock`
If-Match/ETag round-trip; `BlockEditor` holds the ETag, sends If-Match, and on 412
opens a blocking "changed elsewhere — reload" dialog.
Tests
- Handler contract tests: stale-If-Match → 412 (no mutation), matching/absent → success
+ bump, no-op save still bumps, and a two-context racing save → 412; proven
non-vacuous (drop `.IsConcurrencyToken()` → the race test fails).
- Controller tests: malformed If-Match → 400, If-Match threaded to the command, ETag on
GET/PUT, 412 passthrough. SPA: requestWithMeta ETag, replaceBlock If-Match, 412 dialog.

Adds TemplateController mirroring BlockController: groups CRUD, template
CRUD, item replace (PUT full-replace via ReplaceTemplateItems), and a
copy endpoint. Also wires the missing POST /api/blocks/{id}/copy since
CopyBlock's CQRS shape is directly analogous to CopyTemplate.
Fixes CreateTemplateHandler to validate the target template group exists
before insert (previously an unhandled FK violation -> 500), matching the
CreateBlockHandler fix (1e34e00e) for the same class of bug.
New DTOs in ErsatzTV.Core/Api/Scheduling; TimeSpan start times serialize
the same way as PlayoutResponseModel.DailyRebuildTime.

Adds BlockController (block groups + blocks CRUD, items GET, full replace,
non-persisting preview) mirroring ScheduleController, plus four scheduling
search picker endpoints on SearchController (collections, television shows,
television seasons, smart collections). Response DTOs in ErsatzTV.Core/Api/
Scheduling; request DTOs with ToCommand index auto-assignment.
