CHANGELOG.md

@@ -9,7 +9,7 @@
 - **@playwright/test pinned as devDependency** (`1.63.0`, matching the shared remote browser server image and the global install) so CI is self-contained; still excluded from the runtime image via .dockerignore (comment updated), prod-deps stage unaffected
 - `AGENTS.md`: "Change process" + "E2E tests" rewritten for the PR workflow — feature branch off master → commits with CHANGELOG entry + version bump → PR to master → CI (build→unit→e2e) green → merge → tag on master → manual production deploy via `docker compose up -d --build`; no direct pushes to master, CI never deploys
 - **CI build reliability + caching** (after first dind runs): the e2e image is now built with `--progress=plain` before `up -d` so BuildKit step output lands in job logs instead of being hidden by auto progress; Dockerfile bun installs use a BuildKit cache mount (`/root/.bun/install/cache`) that persists on the runner's shared daemon, and CI restores/saves node_modules + the bun cache via actions/cache around dependency install (both steps `continue-on-error` — safe while the runner's cache server is being fixed)
-- **CI retry wrappers for the flaky runner network/DNS** (transient EAI_AGAIN failures seen in runs #10/#11): bun install, dependency install and the e2e image build each retry up to 3× with 5s between attempts before failing; the image is pre-built by a dedicated retried step so the E2E step's own build becomes a fast no-op
+- **CI DNS diagnostics, retries removed** (transient EAI_AGAIN failures seen in runs #10/#11): retry wrappers around bun/dep install and the e2e image build were dropped — the flaky runner DNS is a config problem to be fixed on the runner side, not papered over; instead a non-fatal "DNS diagnostics" step logs job-container vs daemon-side resolver config plus per-host lookups (registry.npmjs.org, cdn.playwright.dev, github.com, docker.io) so the next flaky run shows exactly which layer is broken
 - Verified: unit suite 234 green locally; e2e not run locally by design (would deploy to production) — first real pass happens in the PR's CI run
