timothyandClaude Opus 5 af39123e8e fix(616): fix a live 1-based SPA caller and un-cap two MCP playout tools
Findings from the cold cross-family review of 8d35a279/5648f8e9. The review
confirmed the three conclusions in 8d35a279 (the offset math is sound on all 12
paged endpoints; the list DTO really did already carry ChannelId; the new tests
are non-vacuous) but found the previous commits had documented a convention
without checking who actually violates it.

HIGH — a live instance of this issue's own bug class, in the SPA.
web/src/screens/SchedulesScreen.tsx asked for the rerun-collection picker with
`pageNum: 1, pageSize: 1000`. pageNum is 0-based and pageSize clamps to 100, so
the request skipped the first 100 rows: with <=100 rerun collections (the normal
case) the picker was served an EMPTY page and silently offered no rerun
collections at all; above 100 it dropped rows 1-100. Exactly the silent-short-set
failure #616 is about, shipped in the UI. Now `pageNum: 0`, with a vitest that
asserts the offset and is mutation-verified (restoring `pageNum: 1` fails it).

Checked the rest of the SPA rather than assuming: every other pageNum caller is
0-based. CollectionsScreen's paging loop starts at 1 but only after fetching
page 0 explicitly, so it is correct — verified before touching it.

MEDIUM — two MCP tools wrapped paged endpoints while declaring no paging args.
ersatztv_list_playouts and ersatztv_get_playout_items had no pageNum/pageSize,
and ToolArgumentValidator rejects undeclared arguments, so an agent was hard
capped at the first 100 rows with no way to ask for more and no error saying so.
Both now take Page(). A catalog-wide sweep confirmed these were the only two:
the other paged endpoints are not exposed as MCP tools at all.

That same gap made the new ToolCatalog test vacuous in the direction that
mattered — it filtered on tools that ALREADY declare pageNum, so a tool missing
paging entirely escaped it. It now pins the expected set by name, so a new tool
over a paged endpoint has to be added deliberately.

Record corrections (these are read as normative, so over-broad claims are
defects): "every wrapper says 0-based" was false for the OpenAPI surface, whose
12 pageNum parameters carry no description — named as a remaining gap instead of
claimed as done. "Every controller floors with Math.Max" ignored
SearchController's Math.Clamp. The ids-in-rows corollary was stated as an audit
result when PlayoutListItemResponseModel.ScheduleName has no schedule id;
restated as a rule about actionable ids.

Verification: .NET 1900 + MCP 59 pass; web 996 pass across 105 files; tsc clean;
eslint clean; format gate exit 0; no BOMs.

docs/ — task-signal map

Purpose: route a fresh contributor/agent to the minimal set of docs for the task at hand, instead of a mandatory front-to-back read. Update this doc in the same PR that adds, removes, or retitles a doc below, or that changes which sections a task signal points to.

Start here, always

  • CLAUDE.md (repo root) — project intro: architecture, layout, dev commands, conventions, Task Completion Protocol.
  • docs/contributing.md — established code patterns (CQRS/MediatR, LanguageExt, the ChicoryTV SPA, EF Core dual-provider migrations, FFmpeg pipeline, analyzers, testing). Read before any non-trivial change.

Task signal → minimal sections

Knowledge retrieval (MemPalace + catalog + Gitea)

These four rules are the seam agreed with server-management#642 (the Gitea→MemPalace exporter). They apply whether the question comes up via MemPalace, a grep, or a stale comment:

  1. Current conventions/decisions → catalog-first. Start at docs/decisions/README.md; discover via the ErsatzTV-Decisions wing (active) / ErsatzTV-Decisions-Archive (superseded/retired). Resolve by topic/key, never by chasing a file path.
  2. Issue history → evidence, not authority. The Gitea-ErsatzTV wing is historical narrative that may be stale; it never overrides current Markdown.
  3. The breadcrumb rule (the crux behavior change). A file path named inside a historical issue comment (e.g. "grep docs/decisions.md 2026-07-17", "see …") is a breadcrumb, not a live pointer. Find the current rule via the catalog / active wing by concept; do not treat the named path as current. (Why it's safe: still-current → in the active wing, breadcrumb resolves; superseded → the active wing returns the successor and a literal follow lands on a record that announces its own status: superseded; retired → the active wing returns nothing, which is itself the signal. The validator-enforced move-to-archive/ is what prevents the catastrophic "superseded rule read as current" case.)
  4. Fallback when MemPalace is stale/down: docs/decisions/README.md catalog, then rg '^`key: <dotted.key>`' docs/decisions/. MemPalace is never authority nor sole fallback.

MemPalace is candidate discovery only — every passage is verified against its cited Markdown/Gitea source before use. Never derive live queue state from MemPalace, #237, or historical comments; queue state is live Gitea state, retrieved via scripts/select-queue.sh (see docs/handoffs/chicorytv-issue-queue.md). Full retrieval contract (altitude/precedence, staleness bounds, what's mined per issue): docs/handoffs/chicorytv-issue-queue.md → "Knowledge retrieval".

  • docs/decisions/records/<area>/<topic>.md — one active decision record per file, YAML frontmatter (key/title/status/since/supersedes/superseded-by, plus optional stale-after/sources — ersatztv#603), rationale prose in the body. The filename is the key, so one-active-record-per-key is a filesystem property (ersatztv#610). docs/decisions.md and the topic files remain as the lifecycle-schema narrative plus a "Records formerly in this file" index, which is what keeps older date-based pointers resolvable. Generated active view: docs/decisions/README.md (catalog / task router) — start there. Superseded/retired records live in docs/decisions/archive/ and are read only for history, never for "what is the current rule."

Queue state is live Gitea state, retrieved each session via scripts/select-queue.sh — see that file's standing kickoff for the two concurrent tracks (orientation ‖ selection). ersatztv#237 is a closed, archival historical tracker (superseded by startup.parallel-orientation in docs/decisions.md) — not a live pointer.
