Refs #406, server-management#604. Items 1 and 2 of #406 (item 3 landed in PR #407). Root cause of the 2026-07-17 bumblebee incident (load 340, 21 GiB swapped, prod media down until reboot) is CI-induced memory pressure, and the largest single consumer was Roslyn's persistent VBCSCompiler at 7.8 GB RSS. It is a compiler *server*: it outlives the build that started it to keep its heap warm for the next one. In CI there is no next build -- each job container is torn down at the end of the run -- so it is pure cost, and it is the actual reason each job needed a 10 GiB cap. 1. Disable the compiler servers via the workflow's top-level env (UseSharedCompilation, DOTNET_CLI_USE_MSBUILD_SERVER, MSBUILDDISABLENODEREUSE). MSBuild surfaces env vars as properties and only defaults UseSharedCompilation when empty, so the env var wins and every dotnet call is covered without touching each call site. Also set as ENV in the Dockerfile's SDK stage: the workflow env reaches runner-side jobs only, and the `build` job compiles inside `docker build` where it does not propagate -- that is the job server-management#570 measured pegging 5.999/6 GiB, so it is the one that most needs this. Build stage only; the final image is FROM runtime-base, so nothing lands in the shipped image. Verified locally: a default build leaves 1 VBCSCompiler alive, the same build under these vars leaves 0, and ErsatzTV.sln still builds clean (0 errors). Trade-off: csc runs per project instead of via the server, costing some build time. 2. Cap the mysql service (--memory=2g --cpus=2). A runner's container.options applies to the job container ONLY: a live migrations job reported HostConfig.Memory=10737418240 for the job and mem=0 nanocpus=0 for its mysql service, i.e. unbounded. 2g is sized on measurement -- mysql:8.4 with this exact env peaked at 543 MiB during init, 481 MiB idle (probed on bumblebee) -- not on inheritance. Also add a `Report peak container memory` step to the test job (cgroup memory.peak, always(), never fails a build). server-management#604 sizes both runners' caps on that number and it was inherited rather than measured; now every run reports it. Docs: ci-cd.md gains the compiler-server + services-cap sections and the lane table is corrected (PR #407 reverted the #390 lane move without updating it). decisions.md records all three, incl. the standing rule that a services: container never inherits a cap.

docs/ — reading order
Purpose: index of docs/ so a fresh contributor/agent knows what to read and in what order.
Update this doc in the same PR that adds, removes, or retitles a doc below.
Read in this order at session start:
CLAUDE.md(repo root) — project intro: architecture, layout, dev commands, conventions.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.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/testing.md— testing map: what each*.Testsproject /websuite 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.md— append-only "why" log. Check here before challenging an existing convention. Start from its Index, which links the four topic files underdocs/decisions/(large same-topic clusters) and lists the remaining in-file entries.docs/ci-cd.md— build/test/release pipeline, versioning, dependency management.
Also present in docs/:
docs/rest-api.md— REST API design doc for ersatztv#2 (goals, conventions, per-slice plan). Largely superseded day-to-day bydocs/api-conventions.md; read this for the original rationale.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 byscripts/generate-endpoint-index.py/scripts/update-openapi.sh.docs/handoffs/chicorytv-issue-queue.md— static session kickoff prompt + workflow lore. Queue state (goal, arc, what's in flight/next) lives in the pinned Gitea tracker ersatztv#237 — read that, not this file, for current state (protocol: decisions.md 2026-07-11).docs/handoffs/rest-api.md— original handoff prompt for kicking off the REST API work (#2).
