Node's internal fs.glob, from some 24.x releases, lstat-probes
<matched>/<next segment> while expanding a ** pattern over a symlinked
file and throws ENOTDIR instead of skipping (observed on node 24.13.0
scanning snapshots/acp/image-compaction's symlinked
system-prompt.expected.md, which failed verify-md-wrap inside
check:ci:static). uniqueRepoFiles now walks with dirent types, never
probing a path under a file, and mirrors fs.glob's dot:false and
follow:false semantics: the four repo-files gate pattern sets enumerate
identically. Broken or cyclic symlinks fail loudly in the caller's
realpathSync, and pattern forms the walker does not model (metacharacters,
a trailing **, empty segments) are rejected up front. repo-files.spec.ts
pins the symlink, broken-link, and rejection behavior.
The per-platform failover repository variables (DSH_CI_FAILOVER_LINUX and
DSH_CI_FAILOVER_WINDOWS) accept a third value alongside the existing
selfhosted routing. Set by a repository writer, the value retargets the
always-on pull-request and master lanes onto the matching hosted-runner
labels (16-core pools map to the 16-vCPU tier, standard legs to 4-vCPU);
unset or any other value keeps today's runners, so the leg is dormant until
a writer opts in - a canary path for capacity fallback, never the default.
Participating jobs: the three enterprise Linux workers, the node-compat
legs, the four Windows lanes, and the all-checks-passed verdict in ci.yml;
expected-filenames; the sandbox bwrap leg; and the two manual benchmark
matrices (4-32 vCPU tiers map to equivalents; 64/96-core rows keep the
fleet labels). Everything pinned to its own runner by spec, credential, or
host capability keeps it under every value, and the release-shaped chains
stay entirely hosted. request-review.yml was retired on master while this
work was in flight and the branch takes the deletion.
Specs pin the new branches: ci-workflow.spec.ts asserts the labels appear
in the extended selectors, and ci-compatible-selfhosted.spec.ts evaluates
the routing mode.
Address the ds-review-bot v5/v6 review on PR #3849:
- Register the shared `lib/json-stream-*.js` chunk in `packageFileExtras` and
order `files` as the workspace-constraints gate requires, so
`pnpm run constraints` passes.
- Re-validate the preset on the Session `agents.resume` actually attached,
closing the TOCTOU window between `observeSession` and the write lease.
- Bound one serialized event line at 32 KiB: an over-long event keeps its
scalar fields, drops structured ones, and at the extreme reduces to `type`.
- Normalize an empty tool-argument string to `{}`, matching the executor.
- Scan only real `--json` flags (stop at `--`, skip a `--session-id` value)
before installing the JSON error override.
