 Update to v0.9.14 (2026-08-28): same procedure, `~/opt/gittally.0.9.13.bak` as the rollback copy; a build was running — interrupted and re-enqueued by the startup recovery as designed (now under its recorded build definition `default`).
 Verified live: `bin/gittally --version` reports v0.9.14 before the start, the service is `active`, `/` answers 200 with v0.9.14 in the footer, the watcher polls without errors, and the deprecation warning for `branches.master.autoBuild` appears once in the log.
 Shipped feature: named build definitions (ADR 0007) — the `builds` section defines jobs with `onPush`/`atTimes` triggers, branch selectors (globs, `activeWithin`), and setting overrides; named builds record under `<branch>@<build>` pools; the v0.9.13 per-slot syntax was removed again.

+Update to v0.9.15 (2026-08-29): same procedure, `~/opt/gittally.0.9.14.bak` as the rollback copy, no build was running.
+Verified live: `bin/gittally --version` reports v0.9.15 before the start, the service is `active`, the API answers, and the watcher polls without errors.
+The leftover `builds.maxConcurrent` in the repository's committed `master` config is ignored with exactly one warning per context instead of failing the configuration — the reason it is tolerated rather than rejected: that config needs a colleague's approval to change, and the installation must not be stuck on a key it is meant to forget.
+Shipped feature: the `.gittally.yml` committed on a branch takes precedence for its `builds` section as well, and the watcher reads it per origin branch (`git show`, cached by head commit) to decide which of that branch's builds are due.
+Verified live within seconds of the start: the build definition `reactivate-pi-test-with-full-pitest`, which exists only on the branch `mihoe/reactivate-pi-test` and not in the `master` config, fired its due 05:00 UTC slot, recorded under the pool `mihoe/reactivate-pi-test@reactivate-pi-test-with-full-pitest`, and ran the branch's `pitestFull` command in the build container inherited from the `master` config.
