Auto-merge green Dependabot updates and group the pm toolchain into one daily PR - #133

Conversation
…ne daily PR Version bumps of @unbrained/pm-cli, pm-ops and pm-changelog are mechanical. Dependabot now checks npm daily and groups the pm toolchain (and other minor/patch updates) into single pull requests; a least-privilege workflow enables squash auto-merge for every non-major Dependabot PR, so it lands as soon as the required checks pass and a failing bump stays open as a defect. pm item: pm-linear-1hnc

Merge Risk: ⚪ Minimal · up to The configured eligibility rules appear to preserve manual review for other major updates. No confirmed merge-blocking issue remains. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The automation is narrowly restricted to Dependabot-authored pull requests and does not execute pull-request code in the merge job. It intentionally removes manual approval for eligible updates, including major toolchain updates. The required branch protections and effective token permissions could not be independently verified.

Reviewer's GuideThis PR changes npm Dependabot to run daily with separate PM toolchain and general dependency groups, then adds a tightly scoped, SHA-pinned workflow that auto-enables squash merging for green eligible updates while preserving manual review for non-PM major updates; repository auto-merge and branch-deletion settings are also enabled.

…sions Review feedback: an update that fetch-metadata cannot classify must not auto-merge, so the condition now requires semver-minor or semver-patch outside the calendar-versioned pm-toolchain group. The job's write scopes are documented, the dependencies group selects every package explicitly, and the item's acceptance criteria name the pm-toolchain exception. pm item: pm-linear-1hnc

What
.github/dependabot.yml: npm is checked daily;@unbrained/pm-cliandpm-*packages arrive as onepm-toolchainPR, other minor/patch updates as onedependenciesPR. Other ecosystems are unchanged..github/workflows/dependabot-auto-merge.yml: for Dependabot PRs only (and only inunbraind),dependabot/fetch-metadata(SHA-pinned v3.1.0) classifies the update; thepm-toolchaingroup (calendar-versioned, so a year rollover reads as semver-major) and every other non-major update getgh pr merge --auto --squash. Workflow default permissions are{}; the job alone getscontents: write+pull-requests: write.Why
Fleet rule ([companion pm-cli-website-6d05]): a pm CLI release must reach every package without a hand-written certification PR. Branch protection still requires
test (22),test (26), so nothing merges red; a bump that fails CI stays open as a real defect. Major updates still need a person. Same change as the reviewed pilot unbraind/pm-presets#118.pm item
