docs: add CLAUDE.md with topic guides under .claude/resources#452
Merged
Conversation
Adds contributor/agent documentation distilled from the June 2026 dependency-update series (#436-#446, #450-#451): - CLAUDE.md: repo overview, quick commands, hard rules, pointers - build-and-images.md: rules.mk semantics (DOCKER_FLAGS=--push default, target-specific PLATFORMS), the three places build args must stay in sync, local build recipes, build-context constraints - runtime-architecture.md: the specialize protocol, per-language functionName semantics, builder contract, language runtime notes - ci.md: e2e vs build-only jobs, the four CI gotchas that caused real failures (stale utils.sh image defaults, unexercised workflow-only PRs, substring filter gates, broken action pins), test harness usage and debugging tips - release-process.md: envconfig-driven releases, release_check.py GHCR gate semantics and reconcile mode, multi-PR train conflict resolution, Fission version pin locations, fission.io sync - environment-notes.md: per-env quirks and history (jvm's source-built fission-java-core, ruby Rack 2.2 pin, php 8.3 extension rules, amd64-only tensorflow, frozen legacy dotnet) All factual claims fact-checked against the current tree.

This captures everything non-obvious learned during the June 2026 dependency-update series (#436–#446, #450–#451) — the things that cost real debugging time: the e2e tests silently testing stale Docker Hub images, workflow-only PRs exercising nothing, the GHCR token semantics for brand-new packages, the
environments.jsonregeneration rule, and per-environment landmines.Verification
