CARD TITLE (intent, not commit subject): Agent state versioning: git-in-container with auto-commit + history/revert API

Autonomous build of board card tsk-fjmxzo.

  • Initialise a git repo inside each agent container at deploy time with
    a .gitignore that excludes secrets and bulk artefacts, and commit
    identity set to the agent slug.
  • Ship a small debounced auto-committer script that runs as a background
    loop inside the container, committing dirty trees with a timestamp +
    changed-file-summary message.
  • Add controller API routes: GET /api/agents/{name}/versions,
    GET /api/agents/{name}/versions/{sha}/diff,
    POST /api/agents/{name}/versions/{sha}/revert.
  • Add changelog fragment and tests for committer, routes, and deployer
    steps.

Docs-Reviewed: agent-coordination.md has no route table; new /api/agents/{name}/versions routes are self-documenting via the route file.

Summary by CodeRabbit

  • New Features

    • Added automatic versioning of agent state, including periodic snapshots and protection for secrets and large artefacts.
    • Added APIs to view state history, inspect changes between versions, and restore a previous state.
    • Agent deployments now create an initial state version and enable ongoing background snapshots.
  • Bug Fixes

    • Improved resilience by treating state-versioning setup failures as non-blocking during deployment.
  • Tests

    • Added coverage for automatic snapshots, deployment integration, history retrieval, diffs, restoration, and access control.

- Initialise a git repo inside each agent container at deploy time with
  a .gitignore that excludes secrets and bulk artefacts, and commit
  identity set to the agent slug.
- Ship a small debounced auto-committer script that runs as a background
  loop inside the container, committing dirty trees with a timestamp +
  changed-file-summary message.
- Add controller API routes: GET /api/agents/{name}/versions,
  GET /api/agents/{name}/versions/{sha}/diff,
  POST /api/agents/{name}/versions/{sha}/revert.
- Add changelog fragment and tests for committer, routes, and deployer
  steps.

Review Change Stack

📝 Walkthrough

Walkthrough

This change adds Git-backed state versioning for agent containers. Deployment initializes each repository and starts an automatic committer. New controller routes list versions, show diffs, and revert state.

Changes

Agent state versioning

Layer / File(s) Summary
Git state helpers and automatic commits
tinyagentos/agent_git.py, tinyagentos/scripts/agent_committer.py, tests/test_agent_committer.py
Adds container Git operations, secret-focused .gitignore rules, automatic dirty-tree commits, and tests for commits, ignored files, and clean repositories.
Deployment Git setup and committer installation
tinyagentos/deployer.py, tests/test_deployer.py
Initializes and commits the agent state repository during deployment, then installs and launches the background committer. Deployment records successful setup steps and continues after failures.
Version history routes and validation
tinyagentos/routes/agent_versions.py, tinyagentos/routes/__init__.py, tests/test_routes_agent_versions.py, changelog.d/tsk-fjmxzo-agent-state-versioning.md
Registers authenticated routes for commit listing, diffs, and reverts. Tests cover successful operations, missing agents or SHAs, container errors, and unauthenticated access. The changelog documents the feature.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to 9d0e2

This PR adds persistent agent history and APIs that can expose or mutate agent state. In its current form, sensitive files may be retained in history, authenticated users may access other agents, revision input is insufficiently constrained, remote-agent operations may target the wrong container, and revert can produce incorrect or partial state. These security and correctness risks make the PR unsafe to merge until addressed.

WARNING: --allow-empty is always passed, so git_add_commit will create empty commits on every call whenever the tree is clean. This pollutes the agent's history (and adds noise to git log / the version-listing API) and is called once at deploy time on a near-empty /root. Drop --allow-empty (or only pass it when actually needed) so clean trees don't produce empty commits.

WARNING: git_config_user ignores the return codes of both git config calls. If either fails (e.g. permissions, missing git binary, the repo was never initialized because an earlier step errored), git_add_commit will then fail with a confusing error like fatal: not a git repository. At minimum, check rc and raise on failure like the surrounding helpers do; ideally capture stderr so the root cause is visible.

WARNING: line.split("|", 4) is fragile — any commit whose message (or author name/email/date) contains | will be misparsed and silently dropped from the version list because len(parts) != 5. That includes the auto-committer's auto: <ts> | <summary> messages once a summary with | appears. Use a delimiter that git cannot produce inside fields (e.g. a non-printable record separator via --format=%H%x00%an%x00...) or pass --no-patch/--format with a safer separator.

WARNING: Any non-zero rc from git show is mapped to a single RuntimeError, and the routes then translate any RuntimeError to HTTP 404 (see routes/agent_versions.py:60-61 and :79-80). That conflates "unknown revision" with infrastructure failures (container down, git error, permission denied, repo not yet initialized), so a transient outage surfaces to the client as 404 sha-not-found. Distinguish the unknown-SHA case (exit 128 with unknown revision / bad revision) from other failures and return 502/503/409 for those.

CRITICAL: git revert --no-commit <sha> can leave the working tree and index with unresolved conflict markers when the revert does not apply cleanly. On non-zero exit the function raises and aborts before the follow-up commit, so the conflict state is never cleaned up. The background agent_committer.py will then happily git add -A and commit those <<<<<<< conflict markers as the next "auto:" commit, permanently poisoning the history that this very API is supposed to expose. Either run git revert --abort on failure (and re-raise), or use git revert --quit / git checkout --theirs to leave the tree clean.

WARNING: int(os.environ.get("COMMIT_INTERVAL", "300")) raises ValueError (and kills the process) if COMMIT_INTERVAL is unset to a non-integer. There is no supervisor, so the committer silently dies and the container loses auto-versioning for the lifetime of the container. Wrap in try/except ValueError and fall back to the default; also log to stderr so it shows up in committer.log.

WARNING: Both _git("add", "-A") and _git("commit", "-m", message) have their return codes discarded. If git add fails (e.g. huge file in a non-ignored path, permissions, locked index) or commit fails (no identity configured, index locked from a previous interrupted commit), the failure is swallowed by the outer except Exception: pass in main() and the committer silently stops committing for the rest of the container's lifetime. At minimum log non-zero return codes and result.stderr so the issue is visible in committer.log.

WARNING: The while True: try: _commit() except Exception: pass loop has no logging, no signal handling, and no back-off. A persistent failure (broken .git, missing user identity after a failed revert, locked index) will cause the script to spin every INTERVAL seconds forever with zero diagnostic output. Log exceptions to stderr (which is already redirected to committer.log by the deployer) and install SIGTERM/SIGINT handlers so an in-flight commit can finish before the container is destroyed.

WARNING: Any exception from git_init / write_gitignore / git_config_user / git_add_commit is caught and logged as a warning, yet deploy_agent still returns {"success": True, ...}. A caller (or UI) inspecting result["steps"] will not see git_init, but success is still true, so the agent appears healthy with no state versioning and no auto-committer. Either append a git_init_failed step on failure, downgrade success to False (or a tri-state), or fail the deploy so the operator notices.

SUGGESTION: _container_name(name) does no validation on name, so paths like /api/agents/..%2F..%2Fetc/versions or names with shell metacharacters are passed straight through into the container name string. FastAPI will not let / through, but URL-encoded variants and other metacharacters (;, &, $) are accepted. Validate name against the same allow-list / regex used when the agent is created (e.g. reuse whatever _req / find_agent requires) before forming the container name.

Restore the requested snapshot, not the requested commit inverse.

Line 93 selects the initial commit. tinyagentos/agent_git.py:106-112 runs git revert --no-commit <sha>, which removes README.md instead of restoring the initial state. The endpoint then reports success for the wrong agent state.

Reverse the commits in <sha>..HEAD, or implement the documented snapshot-restore behavior. Assert that README.md remains and notes.txt is absent after the request.

Propagate Git-log failures to the route.

Line 84 converts a failed git log into []. list_versions therefore returns HTTP 200 with an empty history when the container or repository is unavailable, instead of its intended container_unreachable response. Raise RuntimeError here, or return an explicit failure result for the route to map to HTTP 409.

Make the revert a single Git operation.

Line 107 leaves the index and worktree changed before Line 110 creates the revert commit. During that window, agent_committer.py can detect the dirty tree and commit it first. The follow-up commit then fails, so the API reports a failed revert even though the state changed. Use git revert --no-edit <sha> without --no-commit.

Persist and use the remote container target for version routes.

Remote deployment creates <remote>:taos-agent-{name}, but the agent record does not retain the remote. These routes then pass the unqualified name to exec_in_container(), so remote agents can return local or missing history. Persist the remote and use it for all version operations. Add a remote-agent route test.

Validate sha before calling Git.

git show parses sha as an option. A value such as --output=.bashrc can overwrite a file instead of returning the patch. Restrict sha to the full hashes emitted by git_log and verify that it resolves to a commit before calling git_diff.

Do not count the Git stat footer as a file.

Line 42 counts every non-empty git diff --stat line. The final line is the aggregate summary, so one changed file becomes "2 files changed" and larger changes are also overstated. Exclude the footer or use git diff --name-only to count files.

In `@tinyagentos/scripts/agent_committer.py` at line 42, Update the file-counting

Lead review: holding this PR (lead-blocked) until the 4 CodeRabbit finding(s) are folded. Fix-forward card tsk-4vogow carries them verbatim with the acceptance bar; it builds on exec/tsk-fjmxzo and its PR supersedes this one. Source card tsk-fjmxzo closed.

Closed mechanically: superseded by #2717.

exec/tsk-4vogow (e3aed75) is a strict superset of this PR's exec/tsk-fjmxzo (9d0e294) — every commit here is contained there, and it carries more.

Evidence (compare/9d0e29490...e3aed75b3): status=ahead ahead_by=1 behind_by=0. Both directions are checked: behind_by == 0 proves containment, ahead_by > 0 proves it is a strict superset rather than an identical head — one direction alone cannot tell those apart.

No work is lost. This closes the fix-forward accounting gap the per-repo throttle already assumed was closed (next_card.py:300-307), which until now nothing implemented: a fix-forward is supposed to TRADE an open slot, not add one. Reopen if this reads wrong — the predicate declines on identical, behind, and diverged heads, so a close here means containment was measured.
