+# ============================================================================
+# End-to-end Jira -> GHA agent pipeline. Stages, one workflow:
+#
+#   triage              — /fr --ci --phase 0..1 <KEY>            (intent / research / plan)
+#   build               — /fr --ci --phase 2..5 --resume --draft-pr <KEY>
+#   pr-iterate          — /fr --ci --pr-iterate <KEY>                              (review-comment driven)
+#   ci-failure-iterate  — /fr --ci --pr-iterate --ci-failure <run_url> <KEY>       (main-CI failure driven)
+#   recycle             — /fr --ci --recycle --prior <merged|abandoned> <KEY>      (new -rN PR after prior PR merged/closed)
+#
+# A single `→ In Progress` JIRA rule dispatches `jira-resume`; the cheap
+# `resume-preflight` job reads AI pr-url + the PR's GitHub state + whether
+# AI plan is populated, and emits a route (triage / build / iterate / recycle)
+# that the single `resume-run` job runs as a parameterised stage (no AI-status
+# guard in the rule — the preflight does the disambiguation JIRA can't: it sees
+# whether the PR is open / merged / closed, and whether a build-ready plan
+# exists yet).
+# First-pass triage hands back to Needs Review for plan review; the human's
+# next drag (now finding a plan) routes to build. See ag-dev-prompts
+# docs/jira-agent-pipeline.md §"Re-engagement after Needs Review".
+#
+# Each stage is its own job, gated on the `resume-preflight` route output
+# (the normal path), a forced `workflow_dispatch` stage input (dry-run /
+# debugging), or — for ci-failure-iterate / ci-success-handler — the
+# `workflow_run.completed` event on main CI (CI-driven, not JIRA-driven).
+#
+# The heavy lifting (App-token mint, MCP setup, status/state/PR/cost
+# writebacks, Claude invocation, trace digest, artefact upload) lives in
+# the shared `jira-pipeline` composite action under ag-dev-prompts. This
+# workflow is the thin per-repo stub: it owns triggers, eligibility
+# gating, and the consumer-local prerequisite (setup-nx, which renders
+# .claude/settings.json for the shared action to verify).
+#
+# Consumption channel: ag-dev-prompts is a private repo, so the shared
+# actions are pulled via the @ag-grid/dev-prompts npm package on GitHub
+# Packages (see the shared `external/ag-shared/github/actions/install-ag-dev-prompts`
+# action and the `pr-review.yml` workflow which uses the same pattern). ag-grid pins
+# the `latest` dist-tag (the post-soak distribution track); ag-charts tracks `canary`.

+## 2026-06-08 -- Shared JIRA-pipeline glue: install-ag-dev-prompts + pr-preview publish/cleanup
+
+**Branch:** `feat/jira-pipeline-shared-actions`
+**Ticket:** AG-17085 (JIRA/GHA agent-pipeline rollout) / ag-grid onboarding
+
+### Changes
+
+- **[github/actions/install-ag-dev-prompts/action.yml]** New composite action. Installs the private `@ag-grid/dev-prompts` npm package from GitHub Packages into `$GITHUB_WORKSPACE/.ag-dev-prompts` so the pipeline *engine* actions shipped inside it (`jira-pipeline`, `jira-resume-preflight`, `jira-ci-success-handler`, `jira-pr-plnkr`, …) can be consumed via local-path `uses:`. Inputs: `channel` (npm dist-tag — `latest`/`canary`), `github-token` (default `github.token`), optional `node-version` override. Defaults to the consumer repo's root `package.json` via `node-version-file` so the one action fits every repo. Generalised from ag-charts' repo-local `.github/actions/install-ag-dev-prompts` (which had `node-version: '20'` hardcoded). The engine actions themselves stay on the channel-pinned npm package — only this install glue is shared.
+- **[github/actions/pr-preview-publish/action.yml]** New composite action. Stages caller-resolved UMD bundle file paths (plus any sibling `<file>.map`) under `pr-<N>/`, writes `_publish/.nojekyll`, and deploys to `gh-pages` via `peaceiris/actions-gh-pages@v3` (`keep_files: true`). Skips cleanly (warning, not error) when no listed bundle exists (tooling-only PRs). Inputs: `pr_number`, `files` (newline-separated), `github_token`, `publish_branch` (default `gh-pages`). The product-specific `build:umd`, artifact handoff, and live-test PR comment stay in each repo's `ci.yml` (served URL differs per repo). Caller owns the `pr-preview-gh-pages` job concurrency group.
+- **[github/actions/pr-preview-cleanup/action.yml]** New composite action. Removes a PR's `pr-<N>/` directory from `gh-pages` on PR close (`git rm` + commit + push with rebase-retry). Caller checks out `gh-pages` first with workflow-level `continue-on-error` (the first-run guard — `continue-on-error` is unsupported on steps inside composite actions) and gates the action call on it. Inputs: `pr_number`, `publish_branch` (default `gh-pages`).
+
+### Migration Actions
+
+- [ ] Pull ag-shared in each consumer repo (`yarn subrepo pull ag-shared`). The three new actions arrive automatically.
+- [ ] **ag-charts (per-repo follow-up):** migrate `.github/workflows/jira-agent-pipeline.yml` to `uses: ./external/ag-shared/github/actions/install-ag-dev-prompts`; replace the `ci.yml` `pr_preview` stage+deploy steps with `pr-preview-publish`; replace the `pr-cleanup.yml` `gh_pages_cleanup` remove step with `pr-preview-cleanup`; delete the now-redundant `.github/actions/install-ag-dev-prompts/`. Behaviour must be unchanged (same `…/ag-charts/pr-<N>/…` URLs).
+- [ ] **ag-grid (onboarding, per-repo):** add `.github/workflows/jira-agent-pipeline.yml` (channel `latest`), add a `ci.yml` `pr_preview` job + `pr-cleanup.yml`, all referencing the three shared actions. See ag-dev-prompts `docs/jira-agent-pipeline.md` §"Onboarding a new consumer repo" + the onboarding plan.
+- [ ] Operator/JIRA wiring per consumer (GitHub App, secrets/vars, GitHub Pages `gh-pages` branch, the `→ In Progress → jira-resume` Automation rule).
+
+### Notes
+
+The shared actions do not change any consumer's `ci.yml`/workflows automatically — they provide the action surface. The engine actions are intentionally NOT moved here: they ship channel-pinned via the npm package, and `ag-shared` has only a single `latest` branch (no `canary`/`latest` separation). The `jira-agent-pipeline.yml` stub also stays per-repo (GHA cannot `uses:` a workflow from a subrepo path).
