Archive 21 implemented triplets whose shipped decisions are complete and
whose bodies no longer guide future work (one-off UI chrome, generator
applications whose scripts are self-explanatory, superseded implementation
detail, process history owned by current contracts/skills). Delete 4
rejected triplets whose premises are obsolete: the DeepReadonly proposal
(dev-invariants note now carries the alternative inline), the collapse
tool-owned presentation proposal (superseded by the shipped render-intent
union), retire-mid-turn-steering (steering is now load-bearing across
plan-mode/apiproxy/TUI), and single-session-ACP (automation-only ACP
resolved the question; multi-session isolation is pinned by tests).
Repair every inbound link: retarget intentional historical citations to
archived paths, replace decision-current citations with the surviving
authority, and fix the stale example-execute-over-tsx pointer in
pnpm-workspace.yaml. Re-record pairing sidecars and seal the archive
manifest (append-only; existing seals unchanged).
Keep restore-only and self-hosted stores outside pnpm/action-setup's replaceable install directory, resolving the configured path for every paired cache. Pin Yarn 4 for the generated-project e2e so runner images without Corepack do not fall back to Yarn Classic, and update the bilingual decision record.
AGENTS.md and the Wine Agent Note pair state the run policy: CI owns the
everyday win32 signal; run check:windows-wine only while investigating a
known Windows-related failure, and pre-push selection never includes it.
scripts/wine-windows-gates.sh owns the whole lane — workspace snapshot,
concurrent Node/wineboot/install provisioning, entrypoint resolution, the
vue link, smoke, and the two concurrent blocking gates — so the ci.yml
windows job shrinks to runner provisioning plus one script call, and
pnpm run check:windows-wine runs the identical script locally. The local
path never mutates the working tree, persists the Wine prefix and the
checksum-verified Windows Node zip under .cache/wine-windows/, and falls
back to the cached zip offline. AGENTS.md ceiling 1680 -> 1695 for the
one-line command entry.
- The clone exclusion is now '.runner*' (catches .runner_migrated /
.credentials_migrated, which GitHub writes on migrated runners and
which equally trip the already-configured refusal — hit live during
the 2026-07-27 org-group migration).
- The problem statement now states the verdict runs on ubuntu-latest,
scopes the switch to enterprise Linux-pool outages, and names the
residual dependency: node-compat/python-sdk/windows stay standard-
hosted, so a broader hosted-capacity failure still blocks the
verdict, with Windows the only leg lacking any in-house substitute.
Static gate green locally: 32 passed, 0 failed.
config.sh only registers; the runner stays offline until svc.sh
install/start. Both language sides updated so emergency capacity
actually comes online.
- serial-linux-selfhosted checks out fetch-depth 0: depth 2 misses
github.event.before on multi-commit or force pushes, failing the
archive verifier on a valid tree. Full fetch is cheap against the
VM's local mirror.
- Runbook (both languages): every remaining admin phrasing (problem
statement, switch heading, alternatives, consequences) now says
writer; and the 'composes with this mechanism' claim about a
master-ref-pinned runner group is replaced with the truth observed
live on 2026-07-27 — master-ref pinning blocks PR failover, and the
shipped posture is repository-scoped all-workflow group access.
Static gate green locally: 32 passed, 0 failed.
The standby lane itself is push-only, but under failover pull_request
jobs do reach these runners with the PR merge ref's workflow. The
workflow comment and the larger-runner note (both languages) now state
that plainly and name the actual boundary — repository membership
(private, forking disabled, Dependabot excluded) — matching the
runbook. Static gate green locally: 32 passed, 0 failed.
- Sweep every remaining 'admin-only' claim (workflow comments, runbook
lines 13/40, topology note, all zh pairs): the variable is
writer-manageable, and the boundary against untrusted code is
repository membership (private, forking disabled, Dependabot
excluded) — stated identically at every site instead of only in the
'who can flip' paragraph.
- Serial cross-platform reference note (both languages): master now
runs four references — the three hosted OS legs plus the self-hosted
standby drill, linked to the failover runbook.
Static gate green locally: 32 passed, 0 failed.
- serial-linux-selfhosted now fetches depth 2 and passes
DSH_ARCHIVE_BASE_REF=github.event.before, running the same
frozen-archive comparison as serial-linux instead of diffing the
new manifest against itself.
- Runbook (both languages): documents the deliberate dependabot
exception (queued-on-hosted during failover is expected, not a
failed switch); corrects the emergency-capacity bootstrap to
exclude .runner/.credentials when cloning a runner directory; and
replaces the 'admin-only' variable claim with the accurate
trust-model statement — repository variables are writer-manageable,
which in this private fork-disabled repo with an all-workflows
runner group is routing among members, not an escalation.
Static gate green locally: 32 passed, 0 failed.
- All four failover selectors (three workers + the verdict job) and the
paired env/cache expressions now exclude dependabot[bot]: under
failover, dependency-supplied code keeps queueing for the hosted pool
instead of executing on the persistent VM. A delayed Dependabot PR
during an outage is an acceptable cost; dependency code on the
privileged host is not.
- Runbook (both languages): records the shipped failover bounds
(coverage 8, snapshots 12, sized for six instances) and documents
that the verdict job follows the selector too — operators previously
had no explanation for a verdict queued after all workers passed.
- Local static gate green: 32 passed, 0 failed (translation pairing
519 pairs consistent).
The pairing gate requires link target #9 to be byte-identical between
the language sides; my earlier 'fix' pointed the zh side at the zh
runbook and broke the contract. Reverted to the shared target and
re-recorded the pairing hash.
The required windows job moves from windows-2025 to ubuntu-latest, running
checksum-verified Windows Node under Wine at Linux-job wall clock (2m46s
warm vs 7-9min); master's serial-windows native-kernel reference is
untouched, and a new master-only wine-apt-cache job seeds the apt cache
every pull request restores. The experiment workflow folds into ci.yml,
the Agent Note moves to implemented with measured results, and the two CI
topology notes update to the shipped facts.
