fix(777): repair both broken LSPs, and name the surface a subagent can actually reach (#793)
Both C#/TS language servers and the csharp-lsp MCP server were dead; all three are
fixed and each demonstrated with a real find-all-references call in this repo.

Root causes were one shape — a config naming a path this machine does not have,
with nothing checking. None returned a wrong answer; each refused to start:
- csharp-ls: MSBuildLocator needs a dotnet root owning host/fxr; Homebrew's bin
  has none, libexec does.
- typescript-language-server: the LSP workspace root is the repo root but
  `typescript` lives in web/node_modules, and the plugin cannot pass a tsserver
  path (v5 dropped --tsserver-path; lspServers cannot set initializationOptions).
- the csharp-lsp MCP server: .mcp.json named a dotnet install that no longer
  existed, while ~/.codex/config.toml's copy of the same server had been migrated.
  Both files are gitignored, so nothing could compare them.

Corrects defect-shapes-773.md §5.1: the "workflow agents must use csharp-lsp" note
names the MCP server's tools, which subagents DO reach — it was dead because the
server could not start, not because agents cannot call it. The LSP tool is the one
no subagent has been observed to resolve.

Six cold review rounds. Five false greens were found in this PR's own verification
code, each introduced by the fix for the previous one — extracted as #796.

fixes #777

# 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
| Signal | Read |
| --- | --- |
| Session startup / "what's next" (no issue named) | `docs/handoffs/chicorytv-issue-queue.md` (standing kickoff — two concurrent tracks: orientation ‖ `scripts/select-queue.sh 5`) |
| Named-issue pickup | Skip queue selection; go straight to focused retrieval — see "Knowledge retrieval" below, then the issue body |
| Adding/changing a `/api/*` endpoint | `docs/api-conventions.md` checklist + `docs/endpoint-index.md` |
| Adding a ChicoryTV SPA screen | `docs/spa-conventions.md` |
| Scheduling / playout engine work | `docs/domain-model.md` + decisions catalog rows keyed `sched.*` (`docs/decisions/README.md`) |
| Concurrency / optimistic-locking work | `docs/api-conventions.md` §7a/b/c + `docs/decisions/optimistic-concurrency.md` |
| Auth / security-surface work | `docs/decisions/api-auth-security.md` |
| CI / release pipeline work | `docs/ci-cd.md` + `docs/decisions/release-ci-governance.md` |
| Proposing a new guard / CI check / regression test convention | `docs/defect-shapes-773.md` §4 (detector menu + the classes where no detector is plausible), then the two rules every guard must satisfy: `docs/decisions/records/testing/guard-derives-population-from-source.md` and `…/guard-ships-with-mutation-proof.md` |
| Adding / changing / deleting a guard file | `docs/guard-inventory.md` — every guard's row is machine-checked by `scripts/tests/test_guard_inventory.py`, so a new guard must acquire a row before the suite goes green |
| Finding every site that references a symbol (multi-site fix/sweep) | `docs/local-lsp-tooling.md` — which surface answers, and why a delegated agent must be pointed at the `csharp-lsp` MCP tools rather than the `LSP` tool |
| Live local run / Playwright-MCP verification | `docs/e2e-local.md` + `scripts/e2e-local.sh` |
| Adding/changing a UI-E2E browser flow | `docs/e2e-local.md` → "UI-E2E harness" + `scripts/e2e-ui.sh` |
| What does a test suite cover | `docs/testing.md` |
| Legacy Blazor route lookup | `docs/blazor-route-parity.md` (historical #91 phase (b) inventory) |
| "Why do we do X this way" / challenging a convention | **Catalog-first**: `docs/decisions/README.md` (active rows) → follow the row's link to `docs/decisions/records/<area>/<topic>.md` for full rationale. `docs/decisions/archive/<area>/` only for "what did the rule used to be." |
## 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".
## Also present in `docs/`
- **`docs/domain-model.md`** — what the app IS: entity glossary, channel→playout→schedule/block
concept map, where each concept is edited in the SPA.
- **`docs/api-conventions.md`** — checklist for adding/changing a `/api/*` endpoint (controllers,
DTOs, error mapping, auth, OpenAPI regen, tests).
- **`docs/spa-conventions.md`** — playbook for adding a screen to the ChicoryTV React SPA.
- **`docs/e2e-local.md`** (+ `scripts/e2e-local.sh`) — how to run a live local instance for manual
or Playwright-MCP verification.
- **`docs/local-lsp-tooling.md`** — the code-intelligence surfaces (the `LSP` tool's three servers and
the `csharp-lsp` MCP server): how each is configured, which one a **subagent** can actually reach,
the traps (a cold server answers the first query with a confidently partial result), and
`scripts/check-local-lsp.sh` to verify the preconditions. Read before briefing an agent to find
every site referencing a symbol.
- **`docs/testing.md`** — testing map: what each `*.Tests` project / `web` suite covers,
golden-file nets, the timezone-independence rule, how to run subsets, the per-PR verification
gate.
- **`docs/blazor-route-parity.md`** — historical record of the completed #91 phase (b) cutover:
the Blazor Server UI is removed and every legacy route now 302-redirects to its SPA equivalent
(or falls through to the catch-all → `/app`). Read it for the full legacy→SPA route inventory.
- **`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."
- **`docs/ci-cd.md`** — build/test/release pipeline, versioning, dependency management.
- **`docs/rest-api.md`** — REST API design doc for ersatztv#2 (goals, conventions, per-slice plan).
Largely superseded day-to-day by `docs/api-conventions.md`; read this for the original rationale.
- **`docs/mcp.md`** — the `ErsatzTV.Mcp` stdio JSON-RPC MCP server (#58): how it wraps `/api/v1` as
read + cautious-write tools, its config/env vars, auth, security posture, and the tool catalog.
- **`docs/channels.md`** — Channel entity field reference.
- **`docs/m3u-xmltv.md`** — M3U/XMLTV generation overview (`ChannelPlaylist`, `GetChannelGuideHandler`).
- **`docs/fork-strategy.md`** — divergence policy vs upstream ErsatzTV.
- **`docs/design-sync.md`** — Claude Design ↔ repo screen workflow (#92).
- **`docs/endpoint-index.md`** — generated REST endpoint index (method/path/operationId/summary per
OpenAPI tag). Do not edit by hand; regenerated by `scripts/generate-endpoint-index.py` /
`scripts/update-openapi.sh`.
- **`docs/handoffs/chicorytv-issue-queue.md`** — static session kickoff prompt + workflow lore.
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.
- **`docs/defect-shapes-773.md`** — root-cause analysis of the recurring defect shapes across the
whole closed-issue corpus (#773): the measured class ranking, the four families they consolidate
into, the cheapest mechanical detector per class, the classes where **no** detector is plausible,
and an audit of which configured hooks/MCP servers/LSPs are actually invoked. Read it before
proposing a new guard or CI check — §4 is the detector menu, and it argues against enumerating
cases one incident at a time.
- **`docs/guard-inventory.md`** — every executable guard file, what it blocks, whether it is a
`GUARD` or `TOOLING`, and whether it ships a mutation proof (`MUTATION` / `BEHAVIOUR-ONLY` /
`NONE`) with a `file::function` ref. The population is derived from the filesystem and the
workflow/hook call sites and compared for set equality by `scripts/tests/test_guard_inventory.py`,
so a new guard cannot ship unclassified and a renamed test cannot leave a row claiming coverage it
has lost. Guards implemented inline in workflow YAML are deliberately outside that population —
the doc states the limit rather than implying coverage.
- **`docs/tracker-retrofit-triage-237.md`** — audit trail for the #524 triage of ersatztv#237's 111
comments (method, per-comment classification, totals). Evidence for the
`docs.tracker-comment-retrofit` decision; read it only when triaging another over-cap tracker.
- **`docs/handoffs/rest-api.md`** — original handoff prompt for kicking off the REST API work (#2).
