The checkout uses fetch-depth=2, which works for push events (only need
HEAD^1). But for pull_request events the diff base is
github.event.pull_request.base.sha — the tip of the target branch —
which can be many commits behind and therefore absent from the shallow
clone, producing:
fatal: bad object <sha> (exit 128)
Fix: add an explicit `git fetch --depth=1 origin <base-sha>` step that
runs only on pull_request events, keeping push events fast.
Unblocks: PR #1996 (and any other PR targeting a fast-moving staging).

Re-do of the fix that was originally bundled into PR #1995 but never
landed — the second commit on that branch got rejected by GH006
(branch locked by merge queue) after the first commit was already
queued. Only the file-removal commit made it to staging.
Without this trigger, adding "Block forbidden paths" to
required_status_checks deadlocks the queue: every PR sits in
AWAITING_CHECKS forever waiting on a check that can't fire on
gh-readonly-queue/* refs.
Sequence to land safely:
1. (already done) Removed "Block forbidden paths" from required_status_checks
2. (this PR) Add merge_group trigger
3. (after merge) Re-add "Block forbidden paths" to required_status_checks

This monorepo is public. Internal content (positioning, competitive
briefs, sales playbooks, PMM/press drip, draft campaigns) belongs in
Molecule-AI/internal — never here.
## What this PR removes
/research/ (3 competitive briefs)
/marketing/ (45 files: assets, audio, community, copy,
demos, devrel, drip, pmm, press, sales)
/docs/marketing/ (31 draft campaign / blog / brief files)
comment-1172.json + comment-1173.json
test-pmm-temp.txt
tick-reflections-temp.md
83 files removed, 7,141 lines deleted from public history (going forward —
historical commits remain visible in this repo's git log).
## Companion: internal repo absorption
Molecule-AI/internal PR `chore/migrate-monorepo-internal-content-2026-04-23`
absorbs all 79 files into `from-monorepo-2026-04-23/` for curator triage
into the existing internal/marketing/ tree. Bulk-dump avoids file-collision
on overlapping subdirs (audio, devrel, pmm).
## Three-layer enforcement so this can't recur
1. .gitignore — blocks `git add` of /research, /marketing, /docs/marketing,
/comment-*.json, *-temp.{md,txt}, /test-pmm-*, /tick-reflections-*
2. .github/workflows/block-internal-paths.yml — CI hard gate. Fails any PR
that adds a forbidden path. Cannot be silently bypassed.
3. docs/internal-content-policy.md — canonical decision tree for agents
and humans. Linked from the CI failure message.
A separate PR on molecule-ai-org-template-molecule-dev updates SHARED_RULES
to teach every agent role to write internal content directly to
Molecule-AI/internal via gh repo clone + commit + PR (the prevention-at-
source layer; this PR is the mechanical backstop).
