## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work; it ships as a Docker image that self-hosters and managed deployments run. > - The server resolves its own version at runtime in `server/src/version.ts` (`resolveServerVersion()`), which feeds analytics and the server debug panel. > - That resolver derives the real version from `git describe`, and falls back to `server/package.json`'s `version` when git isn't available. > - But `server/package.json`'s version is a static placeholder — CI only stamps the real CalVer at publish, so in source it is never the real version (currently `0.3.1`). > - A Docker image has no `.git` (it's dockerignored), so `git describe` can't run inside it. Every image therefore falls back to the placeholder and reports `0.3.1` in analytics and the debug panel, regardless of which commit it was built from. > - This PR computes the real version once on the CI build runner (where `.git` and tags exist), bakes it into the image, and has `resolveServerVersion()` prefer that stamp when `git describe` is unavailable. > - The benefit: self-hosted and cloud images report their true version instead of a misleading placeholder, with no change to dev checkouts, `git describe`-based resolution, or local `docker build`. ## Linked Issues or Issue Description No public issue exists — describing the bug inline (per the bug report template). **What happened?** Docker images built from `master` (and release tags) report the server version as the `0.3.1` placeholder in analytics and the server debug panel, instead of the real version of the commit the image was built from. **Expected behavior** An image reports the real version of its build commit (e.g. `2026.722.0+51.git.<sha>`), so operators can tell which build is running. **Steps to reproduce** 1. Build the server Docker image from any `master` commit (the `Docker` workflow, `production` target). 2. Run the image and open the server debug panel (or inspect the version reported to analytics). 3. Observe the version is `0.3.1` rather than the commit's real version. **Root cause** `resolveServerVersion()` derives the real version from `git describe`, but the image has no `.git` (dockerignored), so it falls back to `server/package.json`'s `version` — a static placeholder CI only replaces with the real CalVer at publish time. Nothing bakes the real version into the image. **Paperclip version or commit:** reproduces on `master` (`4c55f0d8`) and any published image. **Deployment mode:** self-hosted and managed (both the `production` and `-cloud` images). **Installation method:** Docker image (`ghcr.io/paperclipai/paperclip`). **Related PRs (dedup search):** #9103 (merged — added the `git describe`-based source-install resolution this builds on) and #9637 (closed). Neither bakes a version into the image; this PR closes that gap. No duplicate found. ## What Changed - **`.github/workflows/docker.yml`** — checkout with full history + tags (`fetch-depth: 0`), and a new `Compute build version` step that runs `git describe --tags --match 'v*' --long --dirty` on the pristine runner checkout. The result is passed as a `PAPERCLIP_BUILD_VERSION` build-arg to both the `production` and `-cloud` image builds. - **`Dockerfile`** — the `production` stage takes an `ARG PAPERCLIP_BUILD_VERSION` (default empty) and bakes it into the runtime `ENV`; the `cloud` stage inherits it via `FROM production`. - **`server/src/build-version.ts`** (new) — `readBuildVersion()` / `parseBuildVersion()`, mirroring `build-commit.ts`: reads `PAPERCLIP_BUILD_VERSION` (or a `.paperclip-build-version` file) as a single-token stamp. - **`server/src/version.ts`** — `resolveServerVersion()` prefers the baked build version when `git describe` is unavailable, parsing it with the same rules as a live checkout (`parseGitDescribeVersion`), and falling through to the existing `build-commit` stamp and package version when unset. A live checkout's `git describe` still wins over any stamp. - Tests for the new behavior and the precedence. ## Verification - `pnpm --filter @paperclipai/plugin-sdk ensure-build-deps && tsc --noEmit` in `server/` — clean. - `vitest run server/src/__tests__/version.test.ts server/src/__tests__/build-version.test.ts` — **23 tests pass**, covering: stamped version used when git describe fails, stamp parsed to real CalVer, stamp preferred over the build-commit fallback, on-tag stamp collapses to the release version, a pre-resolved stamp used verbatim, and a live git describe still winning over a stamp. - `git describe --tags --match 'v*' --long` for this commit → `v2026.722.0-51-g<sha>`, which `resolveServerVersion()` reports as `2026.722.0+51.git.<sha>` — no longer `0.3.1`. - Not run locally: the full multi-arch image build (CI-only). The workflow change is verified by inspection; the version is computed on the pristine checkout before any lockfile refresh, so it carries no spurious `-dirty`. ## Risks Low. Additive and image-only: - No runtime behavior changes for dev checkouts (git describe still primary and wins over any stamp) or for local `docker build` (empty arg → server keeps its existing fallbacks). - Not a breaking change; no schema or API surface. The stamp is informational (version reporting only). - `fetch-depth: 0` makes the release-image checkout fetch full history/tags — a modest cost on a workflow that already runs at release cadence with a 60-minute budget. - Rollback: revert the commit; images simply return to reporting the placeholder. ## Model Used Claude Opus 4.8 (`claude-opus-4-8`, 1M-context variant), extended thinking, with tool use / code execution — agentic edits, `tsc` + `vitest` runs, and a `git describe` resolution check. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work (bugfix, not core feature work) - [x] I have searched GitHub for duplicate or related PRs and linked them above (#9103, #9637 — related, not duplicates) - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (`fix/build-version-stamp`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes (no user-facing docs affected; behavior is documented inline in `version.ts` / `build-version.ts` and the workflow/Dockerfile) - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge Co-authored-by: Paperclip <noreply@paperclip.ing>
