# TASK-012: Establish the Codex-Claude handoff workspace

Status: complete — package `57d1c09`, activation tag `handoff/task-006a-ready`
Owner: Codex
Reviewer: Claude

## Outcome

Codex and Claude can continue UBGitea serially from a single current-status document, an explicit delivery roadmap, a reusable working-style prompt, and append-only question/answer mailboxes with unambiguous file ownership.

## Scope

- Included: current implementation summary, remaining roadmap, next Claude assignment, serial workflow prompt, bidirectional question/answer directories, naming and response rules.
- Excluded: Android production-code changes and concurrent implementation.

## Writable paths

- `handoff/`
- `tasks/006a-code-content-classifier.md`
- `tasks/012-agent-handoff-workspace.md`
- `docs/collaboration.md`
- `docs/development-log.md`

## Acceptance criteria

- [x] The handoff identifies the exact reviewed baseline and completed user-visible behavior.
- [x] Remaining features are ordered by dependency, owner, implementation approach, and completion evidence.
- [x] Claude has one immediately actionable task with exact writable paths.
- [x] Questions and answers are stored as separate immutable files in writer-specific directories.
- [x] The prompt prohibits concurrent edits and shared-contract changes without handoff.
- [x] Existing user-owned `assetlinks.json` is not modified or committed.

## Evidence

- Documentation-only change; Markdown paths and cross-references inspected.
- No Android source, build configuration, secret, or external system changed.
