* fix(task): cascade-archive child tasks on workflow delete
Tasks pointing at a deleted workflow_id silently became unreachable
because the FK on tasks.workflow_id was dropped to support ephemeral
quick-chat tasks, so SQLite cannot CASCADE. Service.DeleteWorkflow
now archives every active child task before removing the workflow,
re-using the existing ArchiveTask path (events, worktree cleanup,
agent stop). Frontend confirm copy and button label updated to reflect
the new behavior.
Closes#1279

* fix(task): make workflow-delete cascade race-safe
Address review feedback (Greptile, Claude, cubic): ArchiveTask now returns
a typed ErrTaskAlreadyArchived sentinel so DeleteWorkflow can swallow the
TOCTOU race where a task is archived between ListTasks and ArchiveTask.
Without the sentinel, that race would propagate as an opaque error and
leave the workflow row intact even though every task in the snapshot was
already in the desired state.
Tests:
- TestService_DeleteWorkflow_SkipsConcurrentlyArchivedTask covers the
sentinel-skip path through the cascade.
- TestService_DeleteWorkflow_PartialArchiveErrorPreservesWorkflow covers
the fail-fast contract on a real (non-sentinel) error: workflow row
survives, previously-archived tasks stay archived, retry is safe.
- TestService_ArchiveTask_ReturnsAlreadyArchivedSentinel locks in the
sentinel-error contract DeleteWorkflow relies on.

* fix: gate step_complete_kandev tool on per-step signal flag
Two ADR-0015 follow-up bugs:
- "Wait for agent completion signal" checkbox snapped back because
updateWorkflowStepAction dropped auto_advance_requires_signal from the
PUT body. Add it to the Pick<>, body builder, BackendWorkflowStep, and
transformWorkflowStep.
- step_complete_kandev MCP tool was injected into every first-turn
prompt, polluting context and tempting agents on non-signal-gated
steps to call it. Replace the static description in
kandev-context.md with a {step_complete_section} placeholder filled
only when the current step has auto_advance_requires_signal=true.
Add orchestrator.Service.StepRequiresCompletionSignal helper and
thread it through all four InjectKandevContext call sites.
* fix: address PR 1300 review feedback
- Hoist ProcessOnTurnStart above the first-turn MCP wrap so an
on_turn_start step transition is reflected in the
auto_advance_requires_signal flag baked into the stored/forwarded
prompt (coderabbit, cubic).
- Add Service.WorkflowStepRequiresCompletionSignal step-ID variant and
use it from task_operations.go / autoStartStepPrompt to skip the
redundant GetTask round-trip at hot first-turn launch sites (claude).
- Add table-driven tests covering every silent-false branch and the
positive path of both helpers (greptile, claude, cubic).
* docs(sysprompt): document stepCompleteSection trailing newline contract
Address Claude review suggestion on PR 1300: make explicit that the
constant must end with "\n" because the kandev-context.md template inlines
{step_complete_section} immediately before the next bullet, so the
trailing newline is what separates the two list items.
* fix: restore task-id lookup at startTask wrap site
Address PR 1300 review regression: the previous swap to
WorkflowStepRequiresCompletionSignal(ctx, workflowStepID) silently hid
step_complete_kandev on manual starts where the workflowStepID parameter
is empty but the task is already bound to a signal-gated step in the DB.
The `task` variable in scope at this call site is `*v1.Task` (from the
scheduler) and does not carry WorkflowStepID, so the cheaper step-ID
variant is not applicable here — go back through StepRequiresCompletionSignal
so the repo lookup pulls the canonical step.

* feat(workflow): explicit step-completion signal for auto-advance
Adds `step_complete_kandev` MCP tool + `WorkflowStep.auto_advance_requires_signal`
column so workflow steps can gate their `on_turn_complete` transitions on an
agent-emitted completion signal instead of inferring "done" from any turn-end.
See docs/decisions/0015-explicit-completion-signal-for-auto-advance.md for the
motivation, alternatives considered, and trade-offs.
* fix(workflow): address PR review feedback for explicit completion signal
- Dedup `LoadPendingStepSignal` into `internal/task/models` so the MCP
handler (write site) and the orchestrator (read site) share one decoder.
- Gate the out-of-band subscriber on `WorkflowStep.AutoAdvanceRequiresSignal`
so `step_complete_kandev` is not an unintended manual-advance path for
signalless steps.
- Fail closed on step-load errors in `processOnTurnCompleteViaEngine`: a
loader hiccup must block the transition rather than silently bypass the
gate.
- Reject `step_complete_kandev` for terminal sessions
(Completed / Failed / Cancelled) so the agent gets a clear error instead
of `accepted: true` followed by a no-op.
- Surface bus-publish failures back to the agent instead of swallowing
them — the idempotency guard makes the retry safe and prevents the
session from getting stuck.
- New `TestOnStepCompletionSignaled` covers the subscriber paths
(RUNNING / WAITING+match / stale step / not signal-gated).
- ADR doc fixes: payload field list now matches the wire shape, writer
ownership is documented, the unsubstantiated 250ms-debounce claim is
removed, and the late-signal re-close race is recorded as a deferred
open question.
- Drop the new toggle's HelpTip in favour of an inline description — the
shadcn tooltip portal was intercepting clicks on the agent-profile
dropdown options in the workflow settings E2E.
* fix(workflow): round-2 review fixes for explicit completion signal
- Split `handleStepComplete` into `resolveStepCompleteTarget` +
`publishStepCompletionEvent` helpers so the entrypoint clears funlen
(88 → under 80 lines) and the two halves are independently testable.
- Classify session/task load errors instead of returning `NotFound` for
every failure: use the exported `taskrepo.ErrTaskNotFound` sentinel for
task lookups, substring-match for the session repo (no sentinel today),
and surface anything else as `InternalError` with the raw error logged
but not leaked to the agent — so a transient DB hiccup triggers a retry
rather than session abandonment.
- Pin `step_complete_kandev` explicitly in the mode-specific tool-count
tests: `Contains` in `ModeTask`, `NotContains` in `ModeConfig` and
`ModeOffice`, so accidental dereg or cross-mode registration is caught
by the diff instead of by a still-equal count.
* fix(workflow): round-3 review fixes + defer pipeline-editor toggle
- Defer the "Wait for agent completion signal" sub-toggle to a follow-up
PR. Adding it to the step config card shifts the layout enough that the
agent profile select's Radix popper opens into a sibling tooltip's hover
path, breaking workflow-agent-profile.spec.ts on shard 7. The backend
column ships in this PR — workflows can opt in via the YAML import or
the MCP `update_workflow_step_kandev` tool — and the UI affordance gets
its own iteration where the test interference can be investigated
without blocking the rest of the change.
- Re-publish the bus event on the `already_signaled` short-circuit when
the session is WAITING_FOR_INPUT. Without this, an agent's retry after
the first call's publish failed would short-circuit on the persisted
bag, never fire the subscriber, and leave the session stuck.
- handleStepComplete docstring: drop the non-existent feature-flag claim
and the "audit entry" wording — gating is purely
`WorkflowStep.AutoAdvanceRequiresSignal` and the bag is cleared on the
next turn start with no separate audit trail.
- `step_complete_kandev` tool description: same fix — clarify that the
call succeeds for non-gated steps but the signal is discarded on the
next turn start (no audit history to query later).
* test(workflow): cover handleStepComplete + reword defer-comment
- Add `TestHandleStepComplete_*` (6 subtests, all passing) covering the
uncovered handler paths flagged by Claude/cubic on round 3:
missing-fields validation, session-does-not-belong-to-task ownership
guard, terminal-session rejection (Completed/Failed/Cancelled),
first-call happy path (bag persisted + bus payload shape pinned), dedup
while RUNNING (no re-publish), and dedup while WAITING_FOR_INPUT (the
retry-after-publish-failure path — must re-publish so the subscriber
fires).
- Reword the deferred-toggle comment to drop the YAML-export claim:
the workflow export model doesn't yet serialize
`auto_advance_requires_signal`, so MCP `update_workflow_step_kandev`
is the only configuration path that round-trips today. Note the
follow-up needs to extend the export schema alongside the UI toggle.
* test(workflow): pin signaled_at + drop redundant GetTaskSession on bag-clear
- Assert `signaled_at` is present and parses as RFC3339Nano in
`TestHandleStepComplete_FirstCallAccepted`. The field is part of the
handler's documented response contract; pinning it catches accidental
drop/rename regressions.
- Add `clearPendingStepSignalByID(ctx, sessionID)` as a thin DB-only
variant of `clearPendingStepSignal` and use it from
`executeStepTransition`, where the session struct isn't read after the
clear. Avoids an extra `GetTaskSession` round-trip per transition.
`clearPendingStepSignal(session)` still exists for the
in-memory-mutation case (subscriber's stale-step path).
* fix(workflow): subscriber stale-clear guard + ADR/comment drift fixes
- onStepCompletionSignaled's stale-step path now reads the bag and only
clears it when its current StepID matches the (stale) event's stepID.
Previously the unconditional clear could destroy a valid signal that
the new step's agent had just written when sessions are reused across
steps without auto_start_agent. (Greptile P1.)
- Drop the "feature flag" phrase from WorkflowStep.AutoAdvanceRequiresSignal
docstring — leftover from an earlier draft. The gating is purely the
boolean field; the global flag was removed two rounds ago.
- Merge the two adjacent `if triggerOnEnter` blocks in
executeStepTransition so the full triggerOnEnter=true path reads top-
to-bottom in one place. (CodeRabbit + cubic.)
- ADR 0015 Mechanism section: re-label the SessionStepHistory.Metadata
audit annotation, the `step_complete_signaled` system message, and the
expvar telemetry counters as deferred. They're planned shapes, not
current behaviour — calling them "Audit" / "Chat visibility" /
"Telemetry" in present tense was misleading for future readers.
* fix(workflow): drop subscriber complexity + reload session on stale-clear
- Extract `parseStepCompletionEvent` and `stepIsSignalGated` helpers from
`onStepCompletionSignaled`. Cyclomatic complexity goes 17 → under 15
(cyclop on new code, CI lint regression after the round-6
stale-clear guard).
- The stale-step branch now re-loads the session from the DB before
deciding whether to clear the bag. The previous round-6 fix checked
the local `session.Metadata` snapshot, which can be older than a
concurrent write from the new step's agent — that check could see a
stale signal that had since been overwritten with a valid one and
erase the new bag entry. The narrower load-on-clear is cheap and
closes the cubic P1 hole. (The broader race in
`processOnTurnCompleteViaEngine` reading session.Metadata is the
monotonic-marker open question in ADR 0015; out of scope here.)
* test(workflow): pin stale-event guard's preserve-current-bag side + dedup StringFromAny
- Add `TestOnStepCompletionSignaled` subtest "stale event → valid bag
for CURRENT step is preserved" — fires a stale step-A event while
the bag holds a valid step-B signal, asserts the bag still contains
StepID=step_b after the subscriber runs. Pins the negative side of
the round-6 `existing.StepID == stepID` guard, so a regression that
drops or inverts the guard (and would silently leave signal-gated
steps stuck) fails the test instead of slipping through.
- Promote `pendingSignalString` to exported `models.StringFromAny`
and reuse it from the orchestrator subscriber's
`parseStepCompletionEvent`. Eliminates the byte-for-byte duplicate
helper across the two packages; the bag-shape decoder and the bus-
event decoder now share one source of truth for "missing string".

* feat(tasks): search tasks by PR number in command panel
Typing a PR number (e.g. 1243 or #1243) in the Cmd+K panel now surfaces
the task that PR is associated with, alongside the existing
title/description/repo search.
The github store gains a workspace-scoped ListTaskIDsByPRNumber lookup
over github_task_prs; the task service resolves it through an injected
PRTaskResolver interface (github service wired in cmd/kandev) and merges
PR matches into search results, deduped and respecting the
archived/ephemeral/config filters. Keeping the lookup at the service
layer avoids coupling the task repository to the github schema, so
existing search queries and tests are untouched.
* fix(tasks): scope PR-number search to page 1 and unfiltered queries
Address review feedback on PR-number search:
- Only augment results on the first page of an unscoped search. Running
on every page re-prepended the PR match and truncated a real result
off each subsequent page; running under a workflow/repository filter
leaked tasks that don't satisfy the filter.
- Add idx_github_task_prs_pr_number so the lookup is index-backed
instead of a full scan (pr_number is the 3rd column of the existing
UNIQUE constraint, unusable as a leading key).
- Log instead of silently dropping a task when GetTask fails in the
PR-match loop.
* test(github): dedup PR-lookup test setup into shared newTestStore
Add workspace_id to newTestStore's tasks table and drop the near-identical
newTestStoreWithWorkspaces helper, per review feedback.
* perf(tasks): batch-fetch PR-matched tasks instead of N+1 GetTask
Add a repository GetTasksByIDs and use it in augmentWithPRMatches so PR-number
search loads all matched tasks in one query instead of one GetTask per id,
addressing the N+1 noted in review. Fetch+filter is extracted into a
fetchPRMatchedTasks helper that preserves resolver order and dedup.
* feat(diff): use stored base_branch for diff stats + per-task compare picker
Task-card additions/deletions and the Changes panel were computed against a
hardcoded origin/main → master priority list inside agentctl. For tasks
branched off a release/staging branch this inflated the counts by every
commit since the actual fork point, and the Changes panel grouped unrelated
files alongside the task's real work.
This wires the per-repo task_repositories.base_branch end-to-end into the
agentctl WorkspaceTracker so each repo's diff stats resolve against the
recorded base instead of the integration-branch fallback. A picker on the
Changes panel branch hover card lets the user change the base mid-task; the
new value is persisted via PATCH /tasks/:id/repositories/:repo_id, pushed
live to the running agentctl instance, and the session's cached
base_commit_sha is cleared so the commits panel + cumulative diff refetch
against the new base without a session restart.
Falls back to the existing origin/main → master list for legacy tasks
(empty base_branch) and to the branch tip when no merge-base exists with
HEAD (unrelated histories — local rebase backups, etc.) so the stats and
commits panels stay anchored on the same SHA in every failure mode.
* fix(agentctl): sanitize user-controlled base_branch refs before git exec
CodeQL flagged the picker's user-controlled base_branch payload reaching
exec.Command("git", ..., baseBranch) inside workspace_git_cmd.go as a
command-built-from-user-controlled-source vulnerability. A malicious caller
could smuggle a leading-"-" argument like "-upload-pack=..." that git
itself reinterprets as a flag, even though exec.Command keeps args
separate from the shell.
Adds an IsSafeGitRef sanitizer at every boundary the value crosses on its
way to git: the service write path, the agentctl HTTP handlers
(/workspace/base-branches, /git/log, /git/cumulative-diff), and
WorkspaceTracker.SetBaseBranch itself. Unsafe values are rejected at the
service tier and silently downgraded to the no-override fallback inside
agentctl so a misbehaving caller can't half-break the tracker.
* fix(diff): address PR review blockers and CI lint
- Split UpdateRepositoryBaseBranch into validate/load/apply helpers to drop
cyclomatic complexity below the cyclop limit that gated Run Backend Tests.
- Replace direct m.cfg.BaseBranches reads/writes with getBaseBranches /
setBaseBranches under a dedicated RWMutex. UpdateBaseBranches used to
write under repoTrackersMu while rescan + lazy-subpath callers read under
workspaceTrackersMu, leaving an unsynchronized data race on the map.
- Drop the false 'PR target is auto-wired' claim from the MCP tool
description — GitOperator.CreatePR takes baseBranch as an explicit arg
and never reads the tracker's value.
- Picker no-op guard now compares against currentBase instead of storedBase
so selecting the displayed fallback (legacy task before any picker
change) is treated as no-op instead of triggering a spurious save.
- HTTP handler now maps non-validation service errors to 500 instead of
400, classifying via the existing isValidationError helper plus the new
unsafe-git-ref message.
* fix(diff): regex-based ref sanitiser at every git subprocess sink
CodeQL kept flagging workspace_git_cmd.go:43 even after SetBaseBranch
rejected unsafe values — the taint tracker doesn't follow sanitised stores
through struct fields, so it still saw user input flowing into
exec.Command("git", ..., baseBranch).
Switches IsSafeGitRef to a single regex check (a pattern CodeQL recognises
as a sanitiser barrier) and adds SanitizeGitRef calls inline at every
agentctl call site that splices a user-controlled ref into a git arg:
- workspace_git_status.resolveStoredRef (before the rev-parse probes)
- workspace_git_status.computeBaseCommit (before merge-base/rev-parse)
- workspace_git_status.getAheadBehindCounts (before rev-list)
- agentctl/server/api/git.go runGitLogForRepo + handleGitCumulativeDiff
(before computeMergeBase/GetRevParse on the HTTP TargetBranch)
Behaviour is unchanged for valid refs — only narrows the allowlist (now
[A-Za-z0-9_./-]) so the sanitiser barrier is recognisable to static
analysis. SetBaseBranch's field-store sanitiser stays as defence in depth.
* fix(diff): transform sanitiser at every map read for CodeQL taint flow
CodeQL still flagged workspace_git_cmd.go:43 because:
- handleSetBaseBranches used an IsSafeGitRef bool guard before a verbatim
map[k] = v copy. CodeQL recognises regex-transforming sanitisers but not
bool-guarded passthroughs.
- lookupBaseBranch returned m.cfg.BaseBranches[k] verbatim. Even though
the map was sanitised on write, taint flow across map stores + field
stores loses the sanitised state in the analyser.
Switches both sites to the transforming SanitizeGitRef helper so every
read produces a freshly-sanitised value before it flows to a downstream
git argument. Behaviour is unchanged for valid refs.
* fix(diff): regex transformer sanitiser + guard live push from empty map
CodeQL still flagged the previous SanitizeGitRef because it returned the
input string unchanged on success — an identity passthrough that the taint
tracker doesn't recognise as a sanitiser barrier.
Switches to safeGitRefPattern.FindString so the output comes from the
regex match (not the parameter). IsSafeGitRef now wraps SanitizeGitRef so
the predicate and the transformer share one allowlist.
Also addresses two Claude review blockers:
- collectTaskBaseBranches returns a nil/empty map when the task has no
recorded base_branches; pushing that to agentctl wipes every tracker's
override. Now skipped — the DB row is the source of truth for the next
session launch.
- applyBaseBranchSideEffects now runs on context.WithoutCancel so an HTTP
/ WS request cancel after the task_repositories UPDATE commits can't
leave session.base_commit_sha stale + the live agentctl tracker map
un-pushed, drifting from the persisted row.
* fix(diff): share securityutil.IsValidBranchName + harden error classification
CodeQL still flagged the picker's regex sanitiser as taint passthrough.
Refactors SanitizeGitRef / isSafeBaseBranchRef to delegate to the existing
securityutil.IsValidBranchName helper that agentctl's Rebase / Merge /
RenameBranch already use without being flagged. The shared allowlist also
fixes a Claude review blocker: 'feature/@2024' used to pass the service
validator but get dropped by the agentctl-side check at push time,
silently wiping every tracker's override.
Plus the two error-classification blockers Claude raised on the previous
HEAD:
- WS handler (task_ws_handlers.go wsUpdateTaskRepository) now distinguishes
validation errors (surfaced verbatim) from internal faults (opaque
500-style message). HTTP path already did this via the existing
isValidationError helper.
- MCP handler (handlers.handleUpdateRepositoryBaseBranch) gets the same
treatment via a new isValidationError local to the mcp/handlers
package so raw service error strings stop leaking across the MCP
boundary.
* fix(diff): inline securityutil.IsValidBranchName at every git subprocess sink
CodeQL's interprocedural taint tracking wasn't recognising SanitizeGitRef
as a sanitiser even after it delegated to securityutil.IsValidBranchName
— the wrapper helper + map/field hops between source and sink kept the
flow tainted in the analyser.
Inlines the IsValidBranchName allowlist check (already used inline by
Rebase/Merge in git.go without being flagged) at every call site that
splices a user-controlled ref into a git subprocess argument:
- workspace_git_status.resolveStoredRef (before rev-parse --verify)
- workspace_git_status.computeBaseCommit (before merge-base / rev-parse)
- workspace_git_status.getAheadBehindCounts (before rev-list)
- agentctl/server/api/git.go runGitLogForRepo + handleGitCumulativeDiff
- agentctl/server/api/workspace_base_branches.go handleSetBaseBranches
Behaviour unchanged: same allowlist as Rebase / Merge / RenameBranch
already use. SanitizeGitRef / IsSafeGitRef survive as defence-in-depth
helpers for callers that want a one-line check; they delegate to the same
securityutil helper so the rules stay aligned.
* fix(diff): inline regexp.MatchString at every git subprocess sink
CodeQL still flagged workspace_git_cmd.go:43 even with the inline
securityutil.IsValidBranchName helper — the taint tracker apparently does
not follow into helper functions for the go/command-injection rule on
this path.
Hoists the regex to package-scope vars (safeBranchRefPattern in both
process and api packages) and calls regexp.MatchString directly at each
sink site. Behaviour is identical to securityutil.IsValidBranchName; only
the call form changes.
* fix(diff): SHA-shape allowlist on BaseCommit before downstream git diff
CodeQL still flagged workspace_git_cmd.go:43 because update.BaseCommit
is the OUTPUT of an earlier merge-base / rev-parse call whose argument
list contained a user-controlled branch ref — the analyser treats that
command's output as still tainted even when the input ref was sanitised.
Adds an inline 40-hex SHA-shape allowlist check in enrichWithBranchDiff
right before `git diff --numstat <update.BaseCommit>` so the sanitiser
barrier sits in the same function as the next subprocess call. Behaviour
is unchanged: merge-base / rev-parse already produce SHA-shaped output.
* fix(diff): async tracker refresh + tighten init spread order
Two CodeRabbit/Claude review fixes:
- UpdateBaseBranches stamps each tracker's new baseBranch synchronously
then runs RefreshGitStatus on a background goroutine instead of inside
the picker-save HTTP handler. Per-tracker git subprocesses can each
take ~3-5 calls; serialising them on the request goroutine made the
PATCH response wait for every refresh to finish. The picker UI re-fetches
via the existing WS stream once Refresh emits, so the handler doesn't
need to block.
- updateTaskRepositoryBaseBranch now spreads options.init BEFORE the
required method/body fields so an upstream caller's init overrides
can't replace the PATCH method or the base_branch payload. Matches
the convention deleteTask / moveTask already follow.
* fix(diff): narrow mcp isValidationError + opaque 500 + post-sanitize log count
Three final Claude review threads on the latest commit:
- mcp/handlers isValidationError drops the broad 'invalid' substring so
DB / IO errors whose messages happen to contain 'invalid' don't
misclassify as ErrorCodeValidation.
- task_http_handlers httpUpdateTaskRepository now logs the raw service
error server-side and returns an opaque 'failed to update task
repository' on the 500 path. Stops potential DB / IO detail leakage
through the HTTP boundary.
- workspace_base_branches debug log reports accepted + rejected counts
(post-sanitisation) instead of the pre-filter total so the metric
actually reflects what hit UpdateBaseBranches.

* fix(worktree): promote FallbackBaseBranch when BaseBranch is empty
CreateRequest.Validate previously hard-rejected an empty BaseBranch even
when the caller supplied a FallbackBaseBranch. The fallback is plumbed
specifically so a missing primary branch can degrade into the repo's
default — this lets that path actually fire.

* feat(task): probe provider default branch in add_branch resolve path
Adds an opt-in ProviderDefaultBranchProber seam (impl wired in cmd/kandev)
and threads a ResolveProviderDefaults flag through TaskRepositoryInput so
the add_branch_to_task GitHub-URL path can resolve a real default_branch
before writing the Repository row. Also backfills the existing repo's
default_branch when the probe succeeds and the workspace already had a row
with an empty value. The create_task path keeps its zero-default contract
(executor still backfills after clone).
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(task): surface add_branch_to_task failures instead of silent orphans
AddBranchToTask used to return a success envelope even when the
post-insert worktree materialize step failed on a live task. The
task_repositories row stayed in place with no on-disk worktree, and
provider-URL flows also left an orphan repositories row behind.
Three coordinated changes:
- Gate empty base_branch after resolution with a typed error so no row
is written when nothing can be materialized.
- Track whether the repository row was created by this call and roll it
back on any subsequent failure.
- materializeBranch now returns its error; on a live worktree-executor
task, AddBranchToTask rolls back the task_repositories row and surfaces
the failure. Pre-launch tasks keep the legacy best-effort path so the
next session launch still materializes via the multi-repo prepare flow.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(mcp): classify add_branch base_branch resolution failure as validation
AddBranchToTask now returns a "cannot resolve base_branch" error when the
provider repo's default branch could not be probed. Map it to
ErrorCodeValidation so MCP agents see a user-fixable input issue rather
than an opaque internal error.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(task): defer task.updated until after worktree materializes
Publishing task.updated before materializeBranch ran meant a failed
materialize on a live task would push the new task_repository row to WS
clients and then silently roll it back, leaving stale UI state until the
next poll. Move the event after materialize success so the bus only sees
durable rows. Test now also asserts no task.updated fires on the rollback
path. Renames stubProber.lastProvid to lastProviderArg for clarity.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(task): emit repository.deleted on add_branch orphan rollback
Cleanup callback previously called repoEntities.DeleteRepository directly,
which soft-deletes the row but bypasses Service.DeleteRepository's event
publish. The create path emitted repository.created, so skipping the
delete event left WS subscribers and frontend caches holding a phantom
row after a resolve-then-fail sequence. Route through the service method
so the events stay symmetric. Test now asserts the symmetry.

* fix(task): skip provider probe when workspace already has the repo
resolveRepoInput's add_branch probe fired on every add_branch_to_task
call with a github_url, even when the workspace already had the
provider repo registered with a non-empty default_branch. The existing
row's value would win seconds later via the repo.DefaultBranch fallback,
so the remote git ls-remote round-trip was pure waste — and unnecessarily
hit network on every call. Peek at the workspace registry first and
short-circuit when a usable default_branch is already on file.
Also adds a QA-tier test file covering probe-error fallthrough, bad URL
rejection, registered-repo probe skipping, empty-default backfill, and
the repository_id fast path.

* fix(task): detach rollback paths from caller ctx, log probe-lookup errors
Two adjacent robustness fixes flagged on PR #1264:
1. resolveRepoInput silently discarded the GetRepositoryByProviderInfo
error before the provider probe. A transient DB failure was
indistinguishable from a clean "not found" lookup, so the code would
pay for a network probe instead of failing fast. Surface the error in
logs and skip the probe — FindOrCreateRepository below already hits
the same DB and will return the real cause.
2. The repository-create cleanup callback in resolveBranchAddRepoRef and
the task_repositories rollback in AddBranchToTask both captured the
caller ctx for their DELETE queries. Rollback often runs precisely
because that ctx was cancelled (timeout, client disconnect), and
reusing it would kill the cleanup and orphan the row we just created.
Use context.WithoutCancel so the rollback survives ctx death.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(task): close orphan-row gaps from caller cancel and concurrent create
Two findings from Claude's review on PR #1264:
1. (blocker) materializeBranch called taskAlreadyLaunched(ctx, ...) after
MaterializeBranch returned, using the same caller context that often
failed the materialize in the first place. A cancelled ctx made the
post-failure DB lookup return (nil, err), taskAlreadyLaunched returned
false, and the live-task rollback path silently demoted itself to the
pre-launch best-effort branch — leaving the orphan task_repositories
row the PR exists to prevent. Snapshot the launch state BEFORE
MaterializeBranch (launch state can't change during the synchronous
call) so the rollback decision is anchored to a live-ctx answer.
2. (suggestion) resolveBranchAddRepoRef inferred "this call created the
repo" by comparing the resolved ID against a workspace ListRepositories
snapshot taken before FindOrCreateRepository. A concurrent add_branch
for the same GitHub URL could create the row between snapshot and
lookup; the second request would treat it as "not in my snapshot, must
be mine" and register cleanup against the other request's data. On any
later failure, cleanup would DELETE a repository this call didn't
create and emit a spurious repository.deleted event.
Thread an explicit `created bool` out of CreateRepository through
FindOrCreateRepository → resolveRepoInput → ResolveRepositoryRef so
the cleanup callback fires only when this call physically inserted
the row. The flag is set at the CreateRepository / FindOrCreateRepository
sites themselves and cannot be spoofed by concurrent activity.
resolveRepoInput's branches were extracted into resolveRepoInputGitHub /
resolveRepoInputLocal helpers to keep the parent function inside the
cyclomatic-complexity and cognitive-complexity budgets after the signature
change.

* feat(mcp): accept repository_url and local_path on add_branch_to_task_kandev
Mirror create_task_kandev's repo-locator surface so agents can attach a
branch without first looking up the repository UUID. The MCP tool now
takes repository_id OR repository_url OR local_path; the service
resolves alternatives via the same workspace-scoped find-or-create
path used by create_task.
* fix(mcp): run executor guard before repo resolution on add_branch_to_task
ResolveRepositoryRef may FindOrCreateRepository / CreateRepository
inside the github_url / local_path paths. Running it before
requireWorktreeExecutorForBranchAdd let a rejected add_branch call
on a docker/sprites/SSH task leak an orphan Repository row into
the workspace.
Move the executor check ahead of resolution and add a regression
test that asserts ListRepositories count is unchanged after a
rejected call with a brand-new github_url.
* test(mcp): assert task_id default in add_branch local_path test
* fix(mcp): reject multiple repo locators on add_branch_to_task
resolveRepoInput applies a silent precedence (repository_id >
github_url > local_path), so an agent that accidentally supplies
two of the three locators got a behaviour change with no signal.
Reject at the WS handler with a clear error so the mistake is
surfaced.
Also refresh the AddBranchToTask docstring to document the new
LocalPath / GitHubURL inputs and to correct the workspace-membership
check ownership (now enforced by ResolveRepositoryRef → resolveRepoInput
for the alternative paths).
* fix(mcp): classify resolve_repository errors as validation, not internal
Failures from ResolveRepositoryRef are user-fixable input mistakes
(malformed URL, unknown local_path, cross-workspace repository_id).
Without a matching case the wrapper "resolve repository: ..." message
fell through to ErrorCodeInternalError, so an agent that supplied
e.g. a bitbucket URL saw a server-fault code instead of a validation
error it could correct.
* fix(mcp): narrow add_branch error classification + use wire field name
Two follow-ups to the round-3/4 review feedback:
- Mutual-exclusion error mentioned the MCP tool alias `repository_url`
but the WS handler sees the wire field `github_url`. A direct WS
caller would see an error naming a field it never passed.
- The broad `"resolve repository: "` prefix classified ALL wrapped
errors as Validation, including DB / system failures from
CreateRepository / ListRepositories inside ResolveRepositoryRef.
Narrow to specific user-fixable patterns (GitHub URL parse failures,
cross-workspace repository_id) so genuine internal errors no longer
masquerade as validation rejections.
* fix(mcp): mutual-exclusion check at MCP tier names agent-facing alias
WS-tier rejection works for direct WS callers but its error mentions
github_url, the wire field — confusing for MCP agents that supplied
repository_url. Move the check up to addBranchToTaskHandler so the
error reads "pass at most one of repository_id, repository_url,
local_path" using the names the agent actually typed. WS handler
still validates as defense-in-depth.

Three areas were broken in the MCP add_branch_to_task flow:
1. Predictable branch names. autoBranchName counted up from existing
branch-N rows. Concurrent add_branch calls raced onto the same name
and the worktree directory leaked ordering. Now uses a random
branch-<3 random chars> suffix via worktree.SmallSuffix.
2. Sibling materialize did not flow to the UI. The materializer
published AgentctlReady with the NEW sibling worktree's path, which
the frontend handler wrote onto the session row — clobbering the
primary's worktree_id/branch and pointing the file browser at the
sibling instead of the task root. Added TaskWorkspacePath to the
payload, detected the sibling case on the frontend (existing
worktree_id != payload's), kept the primary's id/branch, repointed
worktree_path to the task root, bumped commits refetch, and dropped
the pre-multi-repo legacy git-status entry so the Changes panel
stops surfacing the frozen single-repo snapshot. File browser's
resetKey now includes the worktree count so the tree reloads when
the sibling lands.
3. workspace_path promotion + agentctl rescan refused to act on
historical envs. A few envs had workspace_path pointing at the
source repo's local_path (orchestrator computeWorkspacePath fallback
to req.RepositoryPath when resp.WorktreePath is empty) instead of
the primary worktree. The materializer's promotion gate compared
against env.WorkspacePath's parent, so those envs were never
promoted, and agentctl's resolveRescanPath only accepted
parent-of-current so the rescan to the real task root was rejected.
Trackers stayed on the wrong directory and the sibling's commits
never appeared in the Commits panel even after a full reload.
Anchored promotion on env.TaskDirName (basename cross-check) and
added a recovery branch to resolveRescanPath that accepts any
absolute directory which actually contains git-repo subdirs — the
bearer-token middleware already gates the endpoint and
scanRepositorySubdirs validates the children, so the relaxed check
stays safe.

* feat(tasks): multi-branch tasks — N (repo, branch) pairs per task
Extends multi-repo into multi-branch so a single task can hold multiple
worktrees on the same repo (one per branch). Sibling worktrees layout at
<task>/<repo>/ + <task>/<repo>-<slug>/, dedicated PRWatch per branch,
live agentctl tracker rescan + frontend store updates so the UI splits
PRs / files / commits per branch without a session restart. MCP
add_branch_to_task_kandev tool is shielded to the worktree executor.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(web): unify multi-branch repo label as <repo> · <branch> across panels
PR Changes and Commits panels rendered repo labels differently for multi-branch
tasks — Commits showed "kandev · feature/x" while PR Changes leaked the raw
"kandev-feature-x" agentctl tracker tag. Reformat tracker-tagged repo names via
formatRepoLabel using the longest known-repo prefix so kandev-cli-* doesn't
collapse to kandev · cli-*.
* fix(tasks): address multi-branch PR review — data races, slug collisions, MCP error codes
Backend
- agentctl process.Manager: add repoTrackersMu RWMutex guarding repoTrackers
+ workspaceTracker. Reads snapshot under RLock; RescanRepositories builds
trackers first, takes Lock for swap/append. Validates newWorkDir via
os.Stat before publishing cfg.WorkDir.
- worktree.Manager: reject invalid explicit BranchSlug up-front; cache key
uses sanitized wt.BranchSlug so read/write paths are symmetric.
- worktree.store: narrow isDuplicateColumnError to "duplicate column name".
- task service AddBranchToTask: slug-collision guard rejects feat/a vs feat-a.
- orchestrator resolvePushRepo: two-pass exact-name match before subdir
prefix fallback so "backend" doesn't swallow pushes for "backend-admin".
- executor buildRepoSpecs: duplicate repos always get a non-empty BranchSlug
(falls back to branch-N when both branch fields sanitize to empty).
- MCP handler: classifyAddBranchError maps service errors to NOT_FOUND /
CONFLICT / VALIDATION_ERROR; add ErrorCodeConflict constant.
- MCP server: extract registerAddBranchToTaskTool, register in task mode
only (external mode contract: config tools + create_task_kandev).
- workspace_rescan handler: reject malformed JSON with 400 instead of
silently rescanning the current root.
- branch_materializer: split MaterializeBranch into prepare + finalize
helpers to satisfy the 80-line cap.
Frontend
- existingPrUrl returns undefined when a task has >1 PR so per-repo View PR
buttons take over (no silent linking to a sibling).
- formatRepoLabel checks exact known-repo match before prefix splitting so
"kandev-cli" isn't mislabeled as "kandev · cli".
- Repo chip key now includes base_branch so siblings differing only on
base render as distinct chips.
Docs
- multi-branch spec uniqueness wording aligned with the canonical 4-column
key (task_id, repository_id, base_branch, checkout_branch).
- worktree.CreateRequest.BranchSlug doc describes the sibling layout
(<repo>-<slug>) instead of the obsolete nested form.
* fix(tasks): scope slug-collision check to repo only + use errors.Is for ErrTaskNotFound
- service_branches: drop base_branch from the slug-collision check. Worktree
path is (repo, slug); two rows on the same repo cut from different bases
still collide on disk.
- service_branches: prepareBranchAdd wraps taskrepo.ErrTaskNotFound via
fmt.Errorf with %w so classifiers don't have to substring-match the
formatted task UUID.
- mcp handlers: classifyAddBranchError uses errors.Is(err, ErrTaskNotFound).
* fix(agentctl): sanitize rescan work_dir before os.Stat to clear CodeQL path-injection
CodeQL flagged the rescan endpoint as a path-injection sink (the
HTTP-supplied work_dir flowed straight into os.Stat and downstream
scanRepositorySubdirs). Add validateRescanPath which:
- requires the input to be a clean absolute path with no ".." segments
- rejects anything that isn't equal to or an ancestor of the current
cfg.WorkDir — the only legitimate use case is the branch materializer
promoting <task>/<repo>/ to <task>/
Defense in depth: agentctl binds to localhost, but any colocated process
could otherwise direct it at /etc or the user's home by POSTing
/api/v1/workspace/rescan.
* fix(agentctl): tighten validateRescanPath, close TOCTOU on existingTrackers, add tests
- Drop the strings.Contains(clean, "..") guard. filepath.Clean already
resolves traversal; the substring check rejects legitimate names like
/home/u/..hidden without adding defense (the ancestor check via
filepath.Rel is the real boundary).
- Drop the rel == "." branch in the ancestor check — early return for
clean == currentClean already covers identity.
- Read existingTrackers inside the write-lock section (not under RLock
then re-Lock) so two concurrent rescans can't both see 0 trackers and
double-bootstrap the multi-repo set.
- Add table-driven TestValidateRescanPath covering rejection paths
(relative, descendant, sibling, traversal-cleaned, empty input),
legitimate ancestor promotion, exact match, no-anchor first-launch,
and a /home/u/..hidden dotted-segment case.
* fix(agentctl): break taint flow into os.Stat — derive rescan path from cfg, not HTTP body
CodeQL's go/path-injection trace still flagged manager_rescan.go after the
prior sanitizer because the user-supplied newWorkDir flowed (after
validation) into os.Stat and then into cfg.WorkDir → tracker paths →
workspace_monitor os.Stat sinks.
Replace validateRescanPath with resolveRescanPath: it returns a path
DERIVED from currentWorkDir (no-op = currentClean, promotion =
filepath.Dir(currentClean)) and uses newPath only for comparison, never
as a source for the returned string. os.Stat now receives a path whose
provenance is trusted manager config.
Functionally the legitimate caller (branch materializer promoting
<task>/<repo>/ to <task>/) is unchanged.
* test(agentctl): make TestResolveRescanPath windows-portable
The Linux Backend Tests job passed but the Backend (windows) job rejected
every "absolute" case because filepath.IsAbs("/task/repo") is false on
Windows (no volume letter).
Build inputs via filepath.Join against absRoot() (filepath.Abs of "/" /
"\\") so the same table covers POSIX (`/...`) and Windows (`C:\...`)
without per-OS branches. Keep the traversal-after-Clean case POSIX-only
since filepath.Clean is the shared primitive and that input form needs a
volume to be considered absolute on Windows anyway.
* fix(agentctl): serialize RescanRepositories + re-check trackers under write lock
Two concurrent RescanRepositories calls could both observe an empty
tracker set (between the snapshot read and the bootstrap branch) and both
enter transitionToMultiRepoMode, leaking a duplicate bare-root tracker
and duplicate per-repo trackers. Same race in appendNewRepoTrackers would
double-append the same new child across both callers.
Fix:
- Add rescanMu sync.Mutex on Manager. Acquired for the full body of
RescanRepositories so the snapshot → branch → mutate sequence is
serialized. repoTrackersMu still guards individual field reads from
unrelated goroutines (subscribe/unsubscribe/poll-mode).
- appendNewRepoTrackers re-checks membership inside the write-lock
before appending and drops already-present trackers (Stop + detach
outside the lock). Defense in depth.
- Test: add `dotted segment is legal as promotion` case so the
..hidden-segment promotion path stays exercised.

setProcGroup and killProcessGroup are defined in both
agentctl/server/adapter/ and agentctl/server/process/. The process/

* chore(agentctl): remove orphan helpers from transport/shared
Left over from the ACP refactor. All had zero callers:
- DebugEnabled(): internal debugMode var is checked directly by
LogRawEvent/LogNormalizedEvent — the exported wrapper was unused.
- GetBool, GetMap, GetSlice: only GetString/GetInt are called in acp/normalize.go.
- NormalizeShellResult, NormalizeReadResult, NormalizeCodeSearchResult,
NormalizeModifyResult: normalization moved to acp/normalize.go.
- TruncateIfNeeded, MaxContentLength, MaxFileCount: only used by the
four Normalize* helpers above; removed transitively.
- TraceControlMessage: zero callers in the adapter transport layer.
GenerateUnifiedDiff, SplitLines, DetectLanguage, Tracer, ShutdownTracing,
TraceProtocolEvent, TraceProtocolRequest are alive and kept.

* chore(agentctl): remove unused tool_payload constructors
NewHttpRequest, NewCreateTask, NewSubagentTask, NewShowPlan,
NewManageTodos, and NewMisc have zero callers — ACP normalization
builds NormalizedPayload via struct literals and JSON unmarshaling,
not these factory functions. NewReadFile, NewModifyFile, NewShellExec,
NewCodeSearch, and NewGeneric are kept (live callers in acp/normalize.go).

WithFileExists, WithCommandOutput, WithEnvVar, expandHomePath (their

* chore: remove scattered orphan helpers
Remove dead single-symbol exports verified to have zero callers:
- ParseCronExpression (office/shared/cron.go): NextCronTime covers
all live usages; the validator wrapper was unused.
- IsValidPathComponent, MustJSON (office/shared/helpers.go): zero
callers; GenerateSlug is kept.
- DiscoverUserSkillsAt (office/skills/userhome_discovery.go): exported
wrapper over the private discoverUserSkillsAt; only the internal
DiscoverUserSkills method is wired up.
- Manager.Get (agent/loginpty/manager.go): zero callers; GetByID and
Stop are kept (Stop is tested in manager_test.go).
- DetachedWithValues (common/appctx/appctx.go): zero callers; Detached
is kept.
- Repository.Close no-ops (task/share, terminal/repository): both are
documented no-ops with zero callers.
- TaskBranchName (worktree/config.go): zero callers; the deterministic
TaskBranchNameWithSuffix is kept.
Note: dialect.Now was initially targeted but is tested in
dialect_test.go (same-package call — missed by package-qualified grep).
It remains unchanged.

* refactor(task/repo): split sqlite/base.go (1486 lines) into schema/migrations/queries
base.go grew to 1.85x the 800-line lint threshold by mixing the Repository
struct, schema initialization, ALTER TABLE migrations, recreate-and-copy
table rebuilds, and historical backfills/heals. Split along those seams:
- base.go (58 lines) keeps only the Repository struct, NewWithDB,
newRepository, Close, DB.
- base_schema.go owns the initSchema orchestrator, every init*Schema
function, ensure*Indexes, ensureRunnerProjectionTables, and the
plan-revision backfill that runs as part of initPlansSchema.
- base_migrations.go owns migrate*, recreateTable[Named], runMigrations,
the backfillRow type, and every backfill*/heal* function. Verbatim
function moves with no semantic changes.
- base_queries.go owns sqlLimitClause (still referenced by plan.go,
document.go, message.go).
To keep golangci-lint (new: true) green after the move:
- initSchema's 17 if-return chain becomes a for-each-step loop so
cyclomatic complexity drops from 19 to within the 15 limit.
- initInfraSchema and initSessionWorktreeSchema hoist their DDL strings
into package-level consts (infraSchemaDDL, sessionWorktreeSchemaDDL)
so each function body fits the 80-line funlen cap.
Step ordering in initSchema is preserved exactly (backfillTaskEnvironments
-> backfillTaskEnvironmentRepos -> healTaskEnvironmentWorkspacePaths ->
healDuplicateTaskEnvironments -> ensureTaskEnvironmentTaskUniqueIndex ->
healSessionTaskEnvironmentIDs) so existing prod DBs continue to migrate
correctly.

* feat(task/repo): add BatchGetSessionsByTaskIDs to eliminate task-list N+1
Adds a single repository method that returns every task_session for a list
of task IDs in one chunked IN (...) query, grouped by task_id. The
workspace task-list endpoint previously needed three batched calls
(GetPrimarySessionIDsByTaskIDs + GetSessionCountsByTaskIDs +
GetPrimarySessionInfoByTaskIDs); with this loader the handler can derive
primary session ID, session count, and per-task session info from a
single round trip.
- buildInPlaceholders and chunkIDs land in base_queries.go.
sqliteMaxHostParams=500 keeps each chunk well below SQLite's
compile-time SQLITE_MAX_VARIABLE_NUMBER (999 on older builds, 32766
on newer).
- session.go gains BatchGetSessionsByTaskIDs, which reuses
taskSessionSelectCols / scanTaskSessions / loadWorktreesBatch so the
returned sessions are indistinguishable from ListTaskSessions output
(worktrees populated, JSON snapshots decoded). Empty input
short-circuits with a non-nil empty map.
- SessionRepository interface and Service.BatchGetSessionsForTasks
expose the new method to the handler layer. The three existing
*ByTaskIDs methods are left in place because service_events.go still
uses them for single-task event publishing.
- mockRepository implementations updated in two test files so the
packages still satisfy the interface.
TestBatchGetSessionsByTaskIDs covers the empty-input short-circuit, the
multi-task (3 x 2) case (primary derivation + no cross-task bleed), and
the asked-for-but-missing case (absent from result map).
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* perf(task/handlers): use BatchGetSessionsForTasks in task-list endpoint
buildTaskDTOsWithSessionInfo previously issued three batched queries per
request (GetPrimarySessionIDsForTasks + GetSessionCountsForTasks +
GetPrimarySessionInfoForTasks). Each was already chunked by task_id,
but together they were three round trips for data that can be derived
from one. Collapse to a single BatchGetSessionsForTasks call and derive
primary session ID, count, and per-task primary info in memory.
The JSON response shape is unchanged: dto.FromTaskWithSessionInfo
still receives the same pointer-typed arguments, primarySessionID stays
nil when no primary exists, and sessionCount stays nil for tasks with
zero sessions (matches the existing pointer-when-present contract that
the frontend store hydration depends on).
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(task/handlers): restore JOIN-derived executor type/name in task-list response
buildTaskDTOsWithSessionInfo regressed when it stopped calling
GetPrimarySessionInfoForTasks: extractSessionInfo reads
ExecutorSnapshot["executor_type"] and ExecutorSnapshot["executor_name"],
but those keys exist only on the synthetic snapshot built by the
GetPrimarySessionInfoByTaskIDs LEFT JOIN to executors. The persisted
ExecutorSnapshot JSON uses different keys (e.g. "type" — see
share/builder.go:96), so BatchGetSessionsForTasks alone always yielded
empty executor_type / executor_name fields in the task-list response,
breaking the frontend task card's executor badge.
Fix (caught in code review):
- Handler now calls both BatchGetSessionsForTasks (for primary session
ID and session count) and GetPrimarySessionInfoForTasks (for the
JOIN-derived executor type/name and other session info). Two queries
instead of the original three; correctness preserved.
- New TestGetPrimarySessionInfoByTaskIDs_PopulatesExecutorJoinFields
seeds an executor + primary session, then asserts the JOIN populates
ExecutorSnapshot["executor_type"] / ["executor_name"] on the returned
session. Locks in the contract the handler depends on so a future
refactor that drops the JOIN fails loudly instead of silently
emitting empty fields.

* fix(task/repo): chunkIDs returns empty slice for empty input
chunkIDs previously returned [][]string{nil} for an empty/nil input
(a single chunk whose value is nil). The only current caller
(BatchGetSessionsByTaskIDs) short-circuits empty input before reaching
chunkIDs, so the bug stayed dormant — but any new caller that forgot
the short-circuit would feed a nil chunk to buildInPlaceholders (which
returns "" for nil), produce a `... WHERE task_id IN () ORDER BY ...`
query, and hit a SQL syntax error at runtime.
Make the helper safe by construction: an empty input returns nil
(empty outer slice), so `range chunkIDs(empty, n)` iterates zero
times. Add base_queries_test.go covering:
- Empty/nil input → no chunks (locks the safety contract).
- Single-pass input fits in one chunk.
- Over-threshold input splits into correctly-sized, in-order chunks.
- buildInPlaceholders normal + empty-input cases.

* fix(task/repo): propagate non-ErrNoRows errors in backfillSingleTask executor lookup
`backfillSingleTask` looked up `executors.type` for the legacy executor
referenced by a session and defaulted to `"local_pc"` on any error.
That silently masked driver failures, schema mismatches, and corruption
— every backfilled task_environment would get the wrong executor_type
without surfacing the underlying problem.
Narrow the default to the legitimate case: only `sql.ErrNoRows` (the
executor row was actually deleted, e.g. legacy session whose executor
is gone) falls back to `"local_pc"`. Any other scan error now aborts
the migration with a wrapped error so operators see the real cause.
Adds TestBackfillSingleTask_DefaultsExecutorTypeOnMissingRow which
seeds a session referencing a non-existent executor id and asserts the
backfill still completes with `executor_type = local_pc` — locks in
the legitimate-fallback path.

* fix(task/repo): chunk ListWorktreesBySessionIDs to honor SQLite var limit
ListWorktreesBySessionIDs built its IN-clause from every input session ID
in one shot. BatchGetSessionsByTaskIDs chunks task IDs at 500 to stay
below SQLITE_MAX_VARIABLE_NUMBER (999 on older builds), but its
loadWorktreesBatch step then handed all sessions in that 500-task chunk
to ListWorktreesBySessionIDs un-chunked — so at modest workloads (500
tasks × ≥2 sessions each = 1000 placeholders) the query fails with
SQLITE_RANGE and bubbles up as a 404 on the task-list endpoint.
ListWorktreesBySessionIDs now applies the same chunkIDs / 500 cap that
BatchGet uses. Body extracted to appendWorktreesForSessionChunk so the
public method stays under the 80-line funlen cap.
New TestListWorktreesBySessionIDs_ChunksOverPlaceholderLimit feeds the
method 1001 non-existent session IDs and asserts it returns cleanly —
without chunking, this fails with SQLITE_RANGE on a default-built SQLite.
Also splits TestBatchGetSessionsByTaskIDs (was 98 lines) into focused
subtests + a shared seedBatchSessions helper, satisfying the test-size
convention. The three sub-scenarios (empty input, multi-task grouping,
missing-task absence) now fail in isolation.

* fix(backend): inherit parent workspace for subtasks on all start paths
Subtasks with workspace_mode inherit_parent were provisioning a fresh
worktree and tasks folder instead of reusing the parent's. Two causes:
- propagateInheritedEnvironment ran only in PrepareTaskSession, so the
direct start path (startTask, used by MCP auto-start) never bound the
child session to the parent's TaskEnvironment. Moved it into
prepareSessionForStart so every launch entry point inherits.
- The service CreateTask path did not inherit the parent's repositories
when none were supplied (the UI omits them expecting inheritance), so
the child was repo-less and could not establish/reuse a worktree. Now
mirrors the MCP path: inherit RepositoryID + BaseBranch, drop
CheckoutBranch.
* fix(web): hide executor profile for inherit-parent subtasks
When a subtask inherits the parent's materialized workspace, its
executor is inherited too, so picking an executor profile is
meaningless. Hide the selector under inherit_parent and omit
executor_profile_id from the create payload.
* fix(backend): fail fast when subtask parent-repo inheritance lookup errors
Return the error from inheritParentRepositories instead of swallowing it:
a subtask silently created with no repositories would reintroduce the
fresh-worktree bug at launch. Also clarified that inheritance applies to
any repo-less subtask, matching the MCP path.
* refactor(backend): classify errors via sentinels instead of substring matches
Introduce package-local sentinel errors in the github, task repo, agent
lifecycle, and office/skills packages. Producers wrap with fmt.Errorf("%w: ...")
so callers can classify via errors.Is/errors.As instead of brittle
strings.Contains(err.Error(), ...) checks that break on library upgrades.
Sentinels added (or relocated to errors.go):
- github: ErrInvalidToken (new); ErrInvalidPRURL, ErrTaskNotFound, ErrSelfApprove
moved from service.go.
- task/repository/sqlite: ErrTaskNotFound, ErrOfficeSessionRaceConflict.
- lifecycle: ErrAgentAlreadyRunning, ErrAgentReported.
- office/skills: ErrSkillNotFound, ErrSkillFileNotFound.
Consumers updated to errors.Is/errors.As across orchestrator, task/handlers,
github, and office/skills. AssociateExistingPRByURL switches %v -> %w so the
inner parsePRURL error stays in the chain. process_handlers now uses
errors.Is(err, syscall.ECONNREFUSED) and lifecycle.ErrNoExecutionForSession
plus a small isTimeoutError helper backed by errors.As.
A new taskDeleterAdapter in cmd/kandev/turn_adapters.go translates
taskrepo.ErrTaskNotFound to github.ErrTaskNotFound at the wiring boundary,
avoiding a layering violation between the github and task packages.
The one remaining substring check, in CreateTaskSession, is encapsulated
inside the repo and converts the SQLite UNIQUE-violation message into the
typed ErrOfficeSessionRaceConflict sentinel so callers never see the driver
string.

* test(backend): add TestErrorsAreClassifiable for refactored packages
Pin the new sentinel-based contract for each refactored package. Each test
exercises the producer paths and asserts errors.Is reaches the sentinel
through the wrap chain, and (where applicable) confirms untyped lookalike
strings no longer classify.
- github: isTaskNotFound, AssociateExistingPRByURL/ErrInvalidPRURL,
ConfigureToken/ErrInvalidToken (using a noop secret manager).
- task/repository/sqlite: GetTask, DeleteTask, UpdateTaskState wrap
ErrTaskNotFound.
- task/handlers: isNotFound + isAgentReportedError follow the typed chain.
- orchestrator: each isXError classifies exact + wrapped sentinels, rejects
untyped lookalikes.
- office/skills: readUserHomeSkillInventoryFile wraps ErrSkillFileNotFound;
ErrSkillNotFound survives fmt.Errorf("%w", ...).

* test(github): drop network-hitting subtest from errors_test
The "ConfigureToken wraps ErrInvalidToken when validation fails" subtest
constructed a real PATClient and called GetAuthenticatedUser, which makes
a live HTTP request to api.github.com. That's flaky in CI / offline dev
and violates the unit-test boundary (caught in review).
Replace with a sentinel-survives-wrap-pattern check that locks in the
exact %w/%w shape used by ConfigureToken, plus an assertion that the
inner cause stays reachable through errors.Is. The full ConfigureToken
flow stays covered by service_token_test.go and integration tests.
Remove the now-unused noopSecretManager stub type.

* fix(task): restore "timed out" UX for plain-fmt.Errorf timeout producers
The original createPromptErrorMessage rendered the friendly "Request timed
out…" hint via strings.Contains(err.Error(), "timeout"). The refactor
replaced it with errors.Is(context.DeadlineExceeded) + a net.Error
Timeout() helper — strictly typed. But several upstream producers along
the prompt path (service.WaitForSessionReady, agent-stream connect waits
in lifecycle/session.go and manager_interaction.go, agentctl health waits
in agentctl/client.go and launcher.go, the orchestrator's own
waitForSessionReady) return plain fmt.Errorf("timeout …") with no typed
Timeout() method, so the typed check missed them and the user saw the
generic "Failed to send message to agent" instead.
Add a substring fallback inside isTimeoutError as a UX safety net while
keeping the primary typed paths intact. Lock the contract with table
tests covering all three classes (net.Error timeout, plain string,
context.DeadlineExceeded) so any future trim of the fallback breaks
loudly. Migrating each upstream producer to a typed sentinel is tracked
as out-of-scope follow-up.

* test(backend): tighten classification tests to exercise typed-sentinel contracts
Addresses bot-review feedback on PR #1057:
- task/handlers/errors_test.go: cover all four not-found sentinels
(taskrepo.ErrTaskNotFound, service.ErrDocumentNotFound,
service.ErrTaskPlanNotFound, service.ErrRevisionNotFound) in
TestErrorsAreClassifiable via a table-driven loop, instead of only
one. Drop the spurious Deadline() *time.Time method on timeoutNetErr
— it isn't part of net.Error and the existing `var _ net.Error =
timeoutNetErr{}` line already pins the interface.
- orchestrator/scheduler/scheduler_test.go: testTaskRepository was
still returning the local scheduler.ErrTaskNotFound, which doesn't
satisfy the production processTasks check (now errors.Is on
taskrepo.ErrTaskNotFound). Mirror the real sqlite repo's wrap so the
mock and prod paths agree. The local scheduler.ErrTaskNotFound is
truly dead after that, so drop it from scheduler.go.
- office/skills: the wrap-pattern subtest in errors_test.go was only
testing fmt.Errorf, not production code. Move the contract assertion
to service_test.go (external skills_test package) where it drives
the real GetSkillFromConfig lookup path against an empty in-memory
repository.

* refactor(backend): drop redundant context.DeadlineExceeded check and fix doc grammar
Addresses bot-review feedback on PR #1057:
- task/handlers/message_handlers.go::createPromptErrorMessage: the
explicit errors.Is(promptErr, context.DeadlineExceeded) is redundant
with isTimeoutError, which already matches via errors.As against
Timeout() — context.DeadlineExceeded implements Timeout()==true.
Inline comment documents the consolidation.
- github/errors.go: fix grammar in the ErrTaskNotFound doc comment
("is the sentinel cleanup paths check for to distinguish" →
"is the sentinel that cleanup paths check to distinguish").
