- 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
Docs-Reviewed: agent_versions routes already covered by existing route docs, no route doc changes needed
L1 (agent_git.py:82-91): fold - versions API mis-parses auto-commits because committer subject uses | as delimiter. Changed git_log format to use %x1f as delimiter and split on \x1f. Added test_list_versions_with_pipe_in_subject_parses_all_fields with a subject containing | that asserts all five fields. Test fails on base.
L2 (agent_git.py:107 + routes/agent_versions.py:96-104): fold - reverting to HEAD returns 404. Added git_rev_parse, git_merge_base_is_ancestor, and pre-revert checks: HEAD == sha returns 200 noop; non-ancestor returns 409; dirty tree returns 409; unknown revision returns 404. Added test_revert_to_head_returns_noop, test_revert_non_ancestor_returns_409, test_revert_dirty_tree_returns_409. HEAD case fails on base.
L3 (deployer.py:750-762): fold - committer does not survive container restart. Changed committer install to prefer systemd unit (Restart=always, systemctl enable --now) with nohup as fallback. Appends committer_installed only after unit is active; appends committer_failed or committer_installed_nohup otherwise.
CR1 (agent_git.py:19): fold - SSH key files not excluded from agent history. Added .ssh/ to _GITIGNORE_CONTENTS. Added test_gitignored_ssh_key_not_committed asserting .ssh/id_rsa does not enter history.
CR2 (agent_git.py:83): fold - same delimiter fix as L1.
CR3 (agent_git.py:108): fold - same ancestor/dirty checks as L2.
CR4 (deployer.py:730-762): fold - deploy reports success when state-repository setup fails. Added versioning and versioning_error fields to deploy result; git init failure sets versioning: false and versioning_error without failing the deploy. Added test_deploy_reports_versioning_failure.
CR5 (deployer.py:761): fold - committer_installed appended without verifying start. Now checks systemctl is-active before appending committer_installed; falls back to nohup with committer_installed_nohup or committer_failed.
CR6 (routes/agent_versions.py:99): fold - same revert status code fixes as L2.
CR7 (scripts/agent_committer.py:42): fold - singular Git stat footer not stripped. Replaced --stat footer heuristic with git diff --name-only.
CR8 (scripts/agent_committer.py:55): fold - Git command return codes discarded. _commit now checks return codes and raises on failure; main() logs exceptions to stderr instead of pass.
K1 (routes/agent_versions.py:28): fold - SHA regex minimum length 4 too permissive. Tightened to ^[0-9a-f]{7,40}$.
K2 (routes/agent_versions.py:31): refuted - remote interpolated into incus target without validation. configure_remote_deploy (routes/agent_deploy.py:208) constrains deploy_remote to known worker names via cm.get_worker() lookup; invalid names are rejected at route layer before reaching _container_name.
K3 (agent_git.py:108): fold - same as L2/CR3.
K4 (scripts/agent_committer.py:41): fold - same as CR7.
K5 (scripts/agent_committer.py:54): refuted - return codes discarded and empty commits. _commit() returns early when _is_dirty() is false (line 49), and git commit -m without --allow-empty creates nothing when index is clean.
K6 (deployer.py:757): fold - no check that python3 exists or committer started. Covered by L3/CR5 systemd path with systemctl is-active check.
K7 (deployer.py:730): refuted - /root hardcoded and git init -b main needs git >= 2.28. Agents run as root in container per deployer docstring; base images are Debian bookworm/Ubuntu 22.04+ which ship git >= 2.34.
K8 (routes/agent_versions.py:44): refuted - 404 echoes agent name enabling probing. Route requires authenticated session; GET /api/agents already lists every agent name to same principal.
Docs-Reviewed: routes/agent_versions.py docstring updated with new revert status codes; agent-coordination.md is repo coordination policy, not API reference, no change needed.
- catch InvalidRemoteError in version_diff and revert_version - replace string matching with DirtyTreeError and NotAncestorError - check git rev-parse HEAD return code in git_revert - terminate mocked git log records with NUL bytes in tests - add .aws, credentials, and *.credentials to agent gitignore - serialize state writers with cross-process flock lock in git_revert and agent_committer - report committer push and nohup failures as committer_failed - enforce owner-or-admin authorization on version list, diff, and revert - add integration tests for 403 unauthorized access Docs-Reviewed: no doc change needed for security and bug fixes
…reate /root/.taos before committer install, fail closed on unresolved agent ownership, preserve container_unreachable for execution failures 1. agent_git.py: move commit message to last field in git_log format so filenames containing the field separator cannot corrupt parsing. 2. deployer.py: run mkdir -p /root/.taos before pushing the committer script, and disable versioning when directory creation fails. 3. agent_versions.py: reject list, diff, and revert requests with 403 when agent ownership cannot be resolved from the registry or config. 4. agent_git.py and agent_versions.py: distinguish container execution failures from unknown revisions, returning 409 container_unreachable instead of 404 when the container is unavailable.

Inline comments:
In `@tinyagentos/agent_git.py`:
- Around line 149-150: The no-op decision must be made atomically with the reset
under the shared lock. In tinyagentos/agent_git.py lines 149-150, move the sha
versus head_sha comparison into the locked command alongside the dirty-tree and
reset checks; in tinyagentos/routes/agent_versions.py lines 185-188, always
invoke git_revert after SHA resolution instead of returning noop from the stale
route-level comparison. Add a regression test that commits between the initial
HEAD read and lock acquisition.
- Line 34: Update the ignore configuration containing the exact .env rule to
also ignore .env.* variants, and add or extend the commit test to verify files
such as .env.local are excluded when staging with git add -A.
- Around line 102-104: Update the unknown-revision handling in git_rev_parse and
git_diff to classify “bad revision”, “Needed a single revision”, and “unknown
revision or path” diagnostics as RuntimeError rather than
ContainerUnreachableError, preserving the documented 404 behavior for unknown
SHAs. Add regression tests covering each command’s handling of these
diagnostics.
- Around line 145-164: Update the locked dirty-tree check in the revert flow
around git_merge_base_is_ancestor and exec_in_container so it includes ignored
untracked paths, using Git status options that report all untracked files.
Preserve the existing rejection and successful “reverted” behavior while
ensuring ignored state paths cannot remain outside the target commit.
In `@tinyagentos/deployer.py`:
- Line 749: Update the terminal committer-failure branches around
_committer.exists(), script push, and nohup launch so each reports the
deployment as a versioning failure by raising into the existing exception
handler or setting versioning=False with versioning_error. Add regression tests
covering script-push and nohup failures.

Docs-Reviewed: merge-only commit bringing in already-reviewed dev history verbatim (installer/doc/tooling changes were reviewed on their own PRs before landing on dev); no new installer or tooling behavior introduced by this merge itself.
… variants git_rev_parse and git_diff only recognized the literal string "bad revision", which git never emits for rev-parse --verify or show against an unknown sha (it prints "Needed a single revision" and "bad object"/ "unknown revision or path not in the working tree" instead), so every unknown-revision case fell through to ContainerUnreachableError and the 404 path was dead. Classify on the real phrases, case-insensitively, in both helpers. Also add .env.* to the agent state .gitignore so dotenv variants like .env.local and .env.production are excluded from git add -A, not just the exact .env filename.
A committer can create a new commit after a pre-lock HEAD read and before
git_revert returns, which made the old HEAD-vs-sha comparison stale: the
route could report {"status": "noop"} without ever taking the lock or
actually restoring the requested commit.
Move the decision into the locked script itself: it re-reads HEAD under the
flock and exits 3 to signal noop, so the comparison always reflects the
freshest state. The route no longer does its own HEAD read/compare and
always defers to git_revert after resolving the requested sha.
Also renames the locked script's unused output variable to _out (RUF059).
Docs-Reviewed: revert_version's request/response shape, status codes, and
docstring (200 noop/reverted, 409 dirty/non-ancestor, 404 unknown revision)
are unchanged; only the internal noop-decision timing moved. No route
contract or agent-manual text needs updating.
A missing committer script, a failed script push, or a failed nohup launch only appended "committer_failed" to steps, leaving versioning=True with no versioning_error even though the container would never get a running committer and later agent state changes would silently create no versions. Set versioning=False and versioning_error in all three terminal branches, matching the shape the enclosing except handler already uses for other committer install failures.
