## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The affected subsystem is the heartbeat execution path that turns
issue assignment into adapter-backed work in a selected workspace.
> - PAP-10409 and sibling follow-ups failed before useful adapter output
because project/workspace identity became incoherent.
> - A project-workspace-linked child issue could keep
`projectWorkspaceId` / execution workspace state while losing
`projectId`, then a git-sensitive local adapter could fall through
toward an invalid fallback cwd.
> - Paperclip needs to treat coherent workspace identity as part of the
live-path contract, not only as post-failure cleanup.
> - This pull request documents that rule, repairs issue inheritance,
and blocks git-sensitive adapter launch before it can run from the wrong
cwd.
> - The benefit is a bounded recovery path: affected issues are repaired
explicitly, future malformed workspaces fail fast with a clear recovery
action, and the UI surfaces that reason.
## Linked Issues or Issue Description
Refs #7646
Bug report fields:
- Summary: adapter-backed follow-up issues can fail before doing work
when issue creation/inheritance preserves workspace ids but drops
project identity.
- Affected issues: internal Paperclip issues PAP-10408 through
PAP-10412, especially PAP-10409.
- Steps to reproduce: create a project-scoped parent/follow-up tree
where a child issue keeps `projectWorkspaceId` or an inherited execution
workspace but has `projectId: null`, then launch a git-sensitive local
adapter such as `codex_local`.
- Expected behavior: Paperclip derives or preserves coherent project
identity during issue creation, and heartbeat refuses malformed
git-sensitive workspace launches with one clear recovery action.
- Actual behavior before this PR: the run could reach adapter bootstrap
with an incoherent workspace context and fail with git errors such as
`fatal: not a git repository (or any parent up to mount point /srv)`.
- Root cause: child/follow-up issue inheritance preserved workspace
execution context without coherent project context. That let heartbeat
workspace resolution/adapter launch reach a fallback cwd instead of
refusing the malformed workspace state up front.
## What Changed
- Documented the adapter workspace-coherence live-path precondition in
`doc/execution-semantics.md`.
- Updated issue creation/inheritance so workspace-inheriting issues
preserve or derive project identity, while existing mismatch validation
still rejects incoherent project/workspace combinations.
- Added a heartbeat preflight guard for git-sensitive local adapters
that validates effective cwd, persisted workspace identity, project
workspace identity, and required git metadata before launch.
- Added `workspace_validation` recovery actions for this failure class
and ensured the source issue gets a visible, idempotent recovery
comment.
- Surfaced workspace-validation recovery state in issue rows, blocked
notices, and recovery action cards, including the manual-repair wake
policy label.
- Added focused regression coverage for issue inheritance, all heartbeat
workspace-validation guard branches, recovery display helpers, and UI
recovery components.
## Verification
- `pnpm exec vitest run
server/src/__tests__/heartbeat-workspace-session.test.ts`
- Result: 1 test file passed, 68 tests passed.
- `pnpm exec vitest run
ui/src/components/IssueRecoveryActionCard.test.tsx`
- Result: 1 test file passed, 12 tests passed.
- `pnpm exec vitest run ui/src/components/IssueBlockedNotice.test.tsx
ui/src/components/IssueRecoveryActionCard.test.tsx`
- Result: 2 test files passed, 18 tests passed.
- `pnpm --filter @paperclipai/ui typecheck`
- Result: passed.
- `pnpm exec vitest run
server/src/__tests__/heartbeat-plugin-environment.test.ts
server/src/__tests__/issues-service.test.ts
server/src/__tests__/heartbeat-workspace-session.test.ts
server/src/__tests__/heartbeat-process-recovery.test.ts
ui/src/components/IssueBlockedNotice.test.tsx
ui/src/components/IssueRecoveryActionCard.test.tsx
ui/src/lib/recovery-display.test.ts`
- Result: 7 test files passed, 200 tests passed before the final
guard-branch additions; the changed server file was re-run above.
- UI coverage: `ui/storybook/stories/source-issue-recovery.stories.tsx`
contains rendered scenarios for the generic recovery chip,
workspace-validation recovery chip, blocked notice indicator, recovery
action card, and issue-row chip.
- Screenshot capture attempt: Storybook started successfully on
`http://127.0.0.1:6016/`, but screenshots could not be captured in this
runner because `agent-browser` launched an unusable Chrome binary and
Playwright Chromium failed on missing system library `libatk-1.0.so.0`;
the runner is non-root and lacks passwordless sudo for installing
browser dependencies.
- Hosted CI on final commit `969594e7` is green, including `verify`,
`Build`, `Typecheck + Release Registry`, `General tests (server)`,
workspace suites, serialized server suites, `Canary Dry Run`, and `e2e`.
- Roadmap checked: no duplicate roadmap item; this is a tightly scoped
reliability fix for existing heartbeat/workspace behavior.
- Duplicate PR search checked: no open PR matched `workspace coherence
adapter cwd`.
## Risks
- Medium risk: heartbeat launch is stricter for git-sensitive local
adapters and can now block malformed workspace states before adapter
execution.
- Mitigation: the guard is limited to local git-sensitive adapters and
records a source-scoped recovery action with structured evidence instead
of retrying indefinitely.
- Compatibility: valid project/workspace execution paths continue
normally; explicit project/workspace mismatches remain rejected.

## Model Used
OpenAI Codex, GPT-5-based `codex_local` coding agent with terminal/tool
use. Work was produced through Paperclip issue execution with focused
local test runs.
