So three ACs are cited as covered and aren't. Either the tests were renamed late and the table wasn't updated, or they were planned and dropped — from outside I can't tell which, and the fix differs: rename the rows, or write the tests.
Raising it now rather than after merge, since the citations are being added by this PR and it's cheapest to settle while the context is open. Not a merge blocker from my side.
…n push The workspace push API could publish only to `origin` or to a remote a contribution binding selected, and push preflight returned success on the ordinary path without contacting a remote at all. Push and push-preflight now accept two optional inputs. `remote` names a configured remote, by name or by a URL resolved against already-configured remotes; only the resolved name ever reaches a git command line, so the existing argument allowlist is unchanged. `expected_branch` states the branch the caller believes it is publishing, verified twice on the push path with the branch read as the last git command before the push, so nothing Kandev issues can move HEAD between the check and the push. Preflight now dry-runs the destination it would actually use, reports the remote and branch it validated, and reports `push_no_remote_configured` for a checkout with nowhere to publish. A request naming neither input is unchanged: same commands, same result shape. Contribution routing, its force refusal, and empty-remote first publication are untouched; an explicit target alongside contribution routing is refused rather than overriding it. Ordering is proved rather than asserted. A PATH shim records every git invocation so a test can check that `symbolic-ref HEAD` immediately precedes `push`; a second shim moves HEAD during first publication to exercise the post-baseline refusal window. Also corrects the system design's Security section, which claimed `Push` assigns git output unsanitized. `runGitCommand` already redacts every `push` invocation, dry-run included. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
… published it The second expected-branch verification tagged its mismatch as push_branch_mismatch_after_baseline whenever the empty-remote path was merely engaged, including the case where an earlier request already published the baseline and this request only retired the local marker. emptyRemotePublication now tracks a separate published field, set only on an actual successful baseline push, and Push() gates the second verification on it instead of the broader active flag. Also closes two test gaps found in review: a contribution-routed preflight already omitted PushedRemote/PushedBranch but had no assertion proving it, and currentBranch() already needed to treat a symbolic HEAD outside refs/heads/ as detached per AC-002.11 but had no coverage forcing that literal check instead of a prefix-strip. Deletes a duplicate test that reused another test's body under a name claiming retry-escalation coverage that doesn't exist in this code path.
…ified reread buildPushPlan's no-explicit-target case re-read the current branch via getCurrentBranch instead of reusing the branch resolvePushPlan already verified, leaving a window where HEAD moving away and back between the two reads could publish an unrelated branch's content under the name both verifications had just confirmed. Reuse the verified expected branch directly, and only fall back to a fresh read when no expected branch was supplied (the unchanged default case).
git push --dry-run still invokes the local pre-push hook, which can mutate the worktree or run arbitrary side effects even though preflight's contract is non-mutating. Add --no-verify to the preflight dry-run and allowlist it.

Preflight's history-update-required classification parses git's dry-run push status lines, which only have the expected field layout under --porcelain. The rebase merge of the configured-push-target refactor onto main's independently-added classification feature dropped the flag, breaking TestPushPreflightHistoryClassification.

Applied fixup commit 6e8ffae. It restores exact contribution source-branch checks, fixed noninteractive Git locale handling for reliable history classification, and typed preflight errors. It also adds regression, fan-out, and transport coverage, updates the Git API documentation, and merges current main to clear the conflict. Focused backend and documentation checks pass locally. |

Tip
PR walkthrough: Open the visual walkthrough
A push always goes to
origin(or whatever remote a configured contribution binding selects), so nothing can ask agentctl to keep a copy of a task branch anywhere else, and push-preflight reports success on the ordinary path without checking anything.Today:
GitPushhard-codesorigin(unless a contribution binding is configured), and ordinaryGitPushPreflightreturns success without contacting a remote at all — so it can't validate a destination that isn't a contribution binding either.After this: Push and push-preflight accept an optional explicit remote (by name or URL, resolved only against already-configured remotes) and an optional expected branch. A caller that states the branch it believes it's publishing gets a real guarantee: if the checkout moved off that branch before the push runs, the request is refused instead of publishing different content under a name the caller trusted.
Who hits this: Any Kandev service that publishes task work through agentctl. The auto-push-work-branches follow-up depends on this landing first.
Scope: standalone — the auto-push policy itself (deciding when a branch pushes automatically) is a separate, later change; this PR only makes such a caller expressible.
Not here: exact-OID
--force-with-lease(still emits the bare lease it emits today), any auto-push policy, and creating or configuring the destination remote itself.Important Changes
HEADbetween that check and the push.Validation
go test -race -run Push ./internal/agentctl/server/process/... ./internal/agentctl/server/api/... ./internal/agent/handlers/... ./internal/agent/runtime/agentctl/... ./internal/common/securityutil/...— all green, including PATH-shimmed regression tests that actually moveHEADmid-operation to prove the race window is closed (reverting the fix reproduces the exact failure: wrong branch published, right branch left unpublished).make fmt && make typecheck && make test && make lint && make lint-formatandpnpm run i18n:ratchet(fromapps/web) — all clean; i18n ratchet confirms no web source is touched.make testsurfaces a pre-existing, unrelated cluster of ~76 failures (macOS temp-dir/symlink races in worktree- and managed-runtime-adjacent packages). Reproduced identically against the exact merge-base commit in a scratch worktree, both before and after rebasing onto currentmain; this branch introduces zero new failures.golangci-lint run ./... --new-from-rev=<merge-base>→ 0 issues.python3 scripts/lint-spec-files.py --all→ all specification files passed.apps/web/**files are touched by this diff (confirmed viagit diff --statand the i18n ratchet), so no Playwright coverage is required; the only existing frontend push caller sends neither new field.Possible Improvements
Low risk: fully additive and backward-compatible (both new inputs are optional and default to today's behavior). One residual is spec-accepted and documented as out of scope: for an explicit target with no expected branch, the destination branch name is still read once outside the two-point verification, so an agent shell moving
HEADin that narrow window (outside Kandev's lock) could still race — closing it fully needs an exact-OID--force-with-lease, tracked as a separate follow-up.Checklist
