CARD TITLE (intent, not commit subject): fold #2717 (tsk-4vogow): revert API inverts one commit instead of restoring the snapshot; sha unvalidated before git argv (CWE-88); trace dir committed into agent history (CWE-200); remote container target not persisted

Autonomous build of board card tsk-yn5gze.

REVISION: built on exec/tsk-4vogow (cut at e3aed75b331ba8eb25a6f67c64d5afcb7ce21704), not on dev. That branch's
commits are ancestors of this one. Verified by git merge-base --is-ancestor
before the PR was opened.

  1. git_revert restores snapshot with sha..HEAD range instead of inverting one commit
  2. .taos/trace/ added to gitignore before initial commit
  3. remote field persisted on deploy and used in _container_name for version routes
  4. sha validated against ^[0-9a-f]{4,40}$ before reaching any git argv

Docs-Reviewed: agent_versions routes already covered by existing route docs, no route doc changes needed

Summary by CodeRabbit

  • New Features

    • Added automatic version history for agent state, including periodic snapshots.
    • Added APIs to list versions, view changes, and revert an agent to a previous version.
    • Excluded secrets, trace data, and large artifacts from version history.
    • Preserved remote deployment targets for version operations.
  • Bug Fixes

    • Improved handling of unavailable containers and invalid version identifiers.
    • Reverting now restores the complete state snapshot without leaving intermediate changes.

- 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.
…, 2) git_revert uses single operation, 3) agent_committer excludes Git stat footer
… sha validation

1. git_revert restores snapshot with sha..HEAD range instead of inverting one commit
2. .taos/trace/ added to gitignore before initial commit
3. remote field persisted on deploy and used in _container_name for version routes
4. sha validated against ^[0-9a-f]{4,40}$ before reaching any git argv

📝 Walkthrough

Walkthrough

Agent state is now versioned in per-container Git repositories. Deployment excludes sensitive files, configures agent-specific identity, and starts background auto-commits. New protected routes list versions, show diffs, and revert local or remote agent state.

Changes

Agent State Versioning

Layer / File(s) Summary
Git state repository primitives
tinyagentos/agent_git.py
Adds container-compatible Git helpers for repository initialization, ignore rules, commits, history, diffs, and range reverts.
Deployment initialization and auto-commits
tinyagentos/deployer.py, tinyagentos/scripts/agent_committer.py, tests/test_agent_committer.py, tests/test_deployer.py
Deployment creates the repository and initial commit, configures identity, installs the background committer, and reports deployment steps. Tests cover automatic commits, ignored secrets, clean trees, and setup calls.
Version route integration and remote targets
tinyagentos/routes/agent_versions.py, tinyagentos/routes/__init__.py, tinyagentos/routes/agents.py, tests/test_routes_agent_versions.py
Adds authenticated routes for version listing, diffs, and reverts. Routes validate SHAs, resolve remote container names, and map Git and connectivity errors to HTTP responses. Tests cover success, errors, authentication, revert behavior, and remote targets.
Changelog updates
changelog.d/*agent-state-versioning.md, changelog.d/*agent-versions-fixes.md
Documents agent state versioning and fixes for snapshot reverts, trace exclusions, remote targets, and SHA validation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to d9315

This change adds persistent, remotely managed agent history and rollback behavior, but the current implementation can capture credentials, allow an authenticated user to access or revert another configured agent, report deployment success when history capture is unavailable, and leave state inconsistent during concurrent commits or reverts. These security, deployment, and state-integrity risks should be fixed before merging.

WARNING: SHA regex is too permissive — minimum length 4 collides with many short hex prefixes and allows patterns like dead or face that git will silently resolve to whichever commit matches first.

Real Git SHAs are 40 hex chars; the modern abbreviation is 7+. Consider tightening the minimum and verifying the resolved SHA exists (git rev-parse --verify) before reaching the diff/revert argv. The changelog advertises ^[0-9a-f]{4,40}$ — this is the same regex, so the looseness is intentional, but worth a comment justifying why a 4-char SHA is acceptable here.

WARNING: _container_name interpolates agent['remote'] directly into an incus target spec without validating that it doesn't contain :, /, whitespace, or shell metacharacters. The remote value is later passed to exec_in_container and push_file, both of which prepend incus exec <name> / incus file push ... <name><remote_path> — a malformed remote can split the argv and pivot to a different container or host.

Validate remote against a hostname/alias charset (e.g. ^[A-Za-z0-9._-]+$) on read or at deploy-time persistence (tinyagentos/routes/agents.py:761-762).

CRITICAL: git_revert --no-edit <sha>..HEAD requires a clean working tree and a clean index. The auto-committer runs every 300 s and may leave the tree dirty or with staged-but-uncommitted changes; in that state the revert command will fail with conflicts and leave the agent's state repo in a half-applied state. Worse, the call doesn't check whether the supplied sha is actually reachable / an ancestor of HEADgit revert A..HEAD on an unrelated sha may merge unrelated history or silently succeed with empty content.

Before invoking, verify (git rev-parse --verify sha^{commit}) and that the tree is clean (or stash first). The route already validates the format, but not the reachability.

WARNING: The "strip last line if it contains files changed" heuristic is fragile. git diff --stat can include rename lines (notes.txt -> NOTES.txt | 2 +-) as the last line, or include a binary file line, and the real summary footer can also be absent for rename-only diffs. Result: stale or wrong summary ends up baked into every auto-commit message.

Use git diff --numstat and count lines (excluding the trailing blank), or git diff --name-only for a deterministic file list.

WARNING: _git("add", "-A") and _git("commit", "-m", message) return codes are silently discarded. If git add fails (corrupt .gitignore, permission error, large file blocked by filter) the subsequent git commit may succeed with stale index or fail with no log output — the operator has no signal that auto-commits have stopped working. Add if rc != 0: logger.warning(...) (or print to committer.log) so deploy-time failures surface.

Also, INTERVAL defaults to 300 s but _commit() runs before time.sleep, so the very first commit happens immediately on script start. Combined with the deploy-time initial commit, this can produce two back-to-back empty commits.

WARNING: The committer is launched with bash -c "nohup python3 /root/.taos/agent_committer.py > /root/.taos/committer.log 2>&1 &". There is no check that python3 exists in the base image, that /root/.taos/ exists (it's created only by the script's first run on some bases), or that the process actually started. If python3 is missing (some minimal images ship only python or neither), the deploy will still report committer_installed and the agent will silently lose all future state versioning. Verify with command -v python3 first, and assert the PID file or process is alive before appending the step.

SUGGESTION: _REPO_PATH = "/root" is hardcoded in agent_git.py:17. If the agent base image runs the framework as a non-root user (a common security hardening), git init -C /root will fail with permission denied. Detect the runtime user (e.g. parse /etc/passwd for the framework's expected uid, or whoami inside the container) and pick an appropriate repo path before invoking git_init.

Also git init -b main requires git ≥ 2.28 (Jul 2020); some legacy base images may ship older git and fail silently.

SUGGESTION: list_versions returns 404 with the literal agent name echoed back (f"Agent '{name}' not found"). Any authenticated caller can probe for valid agent names via this and the diff/revert endpoints. If agent names are considered sensitive, return a generic not_found. Otherwise, consider that find_agent only matches the configured name field — an attacker who knows the local container name can still reach the container via the unqualified _container_name path if agent["remote"] is unset, even when the agent is actually remote (stale config). No fix here, just flagging the data flow.

test covering a valid revision with conflicting local changes.

In `@tinyagentos/scripts/agent_committer.py`:
- Around line 41-42: Update the footer-removal condition in the surrounding
line-processing logic to match both singular “file changed” and plural “files

Sensitive Data Exposure (CWE-922)

Exclude SSH key files from agent history.

Deployment writes /root/.ssh/<name> before git add -A. Names such as id_rsa do not match the current ignore patterns, so private keys can enter version history and diffs. Add .ssh/ to _GITIGNORE_CONTENTS.

Use a delimiter that commit subjects cannot corrupt.

The auto-committer places changed filenames in commit subjects. A filename containing | shifts the fields from line.split("|", 4), so the versions API returns incorrect message, author, and date metadata. Use a machine-safe Git format with escaped or NUL-delimited fields.

Reject SHAs that are not ancestors of HEAD.

revert_version passes the request SHA directly to git_revert, which runs git revert --no-edit "${sha}..HEAD". For a valid SHA from another branch, this range can select and revert unrelated current-branch commits. Run git merge-base --is-ancestor "$sha" HEAD first and return an error when it fails.

Do not report a complete deployment when state-repository setup fails.

If any Git setup helper fails, this handler logs a warning and returns a successful deployment. The agent then has no usable state repository, while version routes later map Git failures to container_unreachable. Make repository setup a deployment failure, or return an explicit degraded deployment state.

Append committer_installed only after the process starts.

exec_in_container returns a status tuple. This code discards the result from nohup, then appends committer_installed even when Python is unavailable or the process fails to start. Check both chmod and nohup return codes, then raise or warn without adding the success step.

Map only unknown revisions to 404

git_revert converts every non-zero git revert result into RuntimeError. The handler maps every such error to HTTP 404, so a valid revision with conflicting local changes can return “not found.” Return HTTP 409 for revert-state failures and reserve HTTP 404 for unknown revisions. Add a regression test for this case.

Remove singular Git stat footers.

A one-file change ends with 1 file changed, not files changed. The footer remains in lines, and Line 45 reports 2 files changed for a single changed file. Match both file changed and files changed.

Check Git command failures before continuing.

_git returns nonzero status codes instead of raising. If git add -A fails, this code still runs git commit and then returns normally. The dirty state can remain unversioned, and the background loop suppresses the failure at Lines 60-63.

Raise on either nonzero result, do not commit after a failed add, and log the caught exception in main.

Lead review of d9315c1 against tsk-yn5gze — the four card findings are landed and all four behavioural tests are red on exec/tsk-4vogow (I ran the new test file against the base: 4 failed / 6 passed — test_revert_restores_content, both *_injection_sha_returns_400, test_remote_agent_uses_qualified_container_name). incus exec remote:name is native, so finding 3 is real, not cosmetic.

lead-blocked anyway, fold card tsk-f2ttez (base exec/tsk-yn5gze); source card tsk-yn5gze closed as superseded. Three lead findings on top of the 8 CodeRabbit + 8 kilo comments:

  • L1 agent_git.py:82-91git_log splits %H|%s|%an|%ae|%ai on |, and agent_committer.py:52 writes every subject as auto: {ts} | {summary}. Every auto-commit row comes back with the wrong message/author/email/date. CodeRabbit's delimiter finding is this, but always-on rather than filename-dependent.
  • L2 <sha>..HEAD with sha == HEAD is an empty range → git revert exits 128 → the route returns 404 for the top entry of the versions list. Fold together with the ancestor / dirty-tree / 404-vs-409 findings.
  • L3 the committer is nohup … & via incus exec; it dies with the first container restart and nothing brings it back.

Every CR/kilo finding is numbered on the card with a fold-or-refute instruction (refutations for the argv-split claim, the empty-commit claim, the /root and name-probe suggestions carry the code paths to quote).

Closed mechanically: superseded by #2724.

exec/tsk-f2ttez (0c6e36b) is a strict superset of this PR's exec/tsk-yn5gze (d9315c1) — every commit here is contained there, and it carries more.

Evidence (compare/d9315c10d...0c6e36bfb): 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.
