Engineer Handoff

Use this packet when a POC is ready for engineering review. A POC is not production-ready until engineering/security explicitly approves it.

Purpose And Demo Path

  • Purpose: Demonstrate a local-only task tracker for creating, listing, and completing synthetic tasks.
  • Primary user: Project lead tracking small team follow-ups.
  • Demo path: Start the local app or CLI, create "Draft agenda" for owner-a, view it in open tasks, mark it complete, and confirm it no longer appears in the open list.
  • What this demo proves: The core task lifecycle is understandable and testable.
  • What this demo does not prove: Production persistence, multi-user auth, notifications, public deployment, or real customer data handling.

Setup Run Test Evidence

Record evidence, not claims.

  • Command: make check && make test
  • Date: 2026-05-10
  • Environment: local template example, Python 3.13-compatible workflow
  • Result: pass for template checks; example app is illustrative and not shipped as runnable source
  • Artifact: docs/examples/task-tracker-poc/DESIGN_SUMMARY.md
  • Known failures: none for the documentation example
  • Known flakes: none
  • Accepted by: example engineering reviewer

Architecture And Data

  • Architecture summary: Thin boundary calls a task service using a typed task model and an in-memory store for POC state.
  • Entry points: Future UI/CLI boundary; no runnable app is included in this example.
  • Directory or module map: See docs/examples/task-tracker-poc/DESIGN_SUMMARY.md.
  • Data model: task id, title, owner label, due date, and status.
  • Persisted data: none in this POC.
  • Session-only data: in-memory task list.
  • Derived data: open-task view sorted by due date.
  • External boundaries and typed inputs/outputs: task create request and task response should be dataclass or Pydantic models.
  • Rollback/delete instructions, if relevant: stop the local process; no persisted data exists.

Security Evidence

  • Data classification: public synthetic data
  • Demo data source: generated examples such as owner-a, owner-b, and fake task titles
  • Production data in dev environment? no
  • Secrets scan command/date/result: not applicable for this documentation-only example; no source files, credentials, env files, or secrets-bearing fixtures are included
  • Dependency audit command/date/result, if available: not applicable; example adds no dependencies
  • Auth assumptions: no auth because the POC is local-only and synthetic
  • Access control/RBAC assumptions: not applicable for local synthetic demo; would be required before real team use
  • Audit logging assumptions: not applicable for local synthetic demo; required before sensitive case or investigation data
  • Data retention/deletion assumptions: no persisted data; retention/deletion policy required before storage is added
  • PII/confidential data handling: prohibited in this POC
  • Export controls/legal hold concerns: not applicable to synthetic data; legal review required before real case data
  • Encryption and secrets management: no secrets or persisted data in this documentation example
  • Required approvals before public or internal production use: security, legal, and engineering
  • Deployment scope: localhost or documentation example only
  • Skipped security checks and rationale: dependency audit skipped because no dependency changes are part of the example
  • Security reviewer signoff: approved for local synthetic POC scope

Test Evidence

  • Tests run, with command/date/result: make check, 2026-05-10, pass for template validation
  • Smoke proof for the top demo path: documented manual path is create, list, complete, and confirm hidden from open list
  • Unit coverage for core behavior: proposed for create validation, due-date sorting, and complete behavior before implementation
  • Boundary test or manual substitute for persistence/API/auth/LLM paths: manual substitute accepted because there is no persistence, external API, auth, or LLM path in this example
  • Skipped tests and reviewer acceptance: runnable app tests skipped because this is a documentation example; accepted by example test reviewer
  • Residual test risk: implementation must add tests before code if this example becomes a real app

Risks And Limitations

  • Known bugs: no runnable app is included
  • Known tech debt: persistence and auth are deliberately out of scope
  • Product limitations: no notifications, permissions, imports, exports, or mobile UI
  • Security limitations: not suitable for public deployment or real user data
  • Operational limitations: no deployment, backup, monitoring, or rollback plan beyond local process shutdown
  • Acceptable for POC? yes, as a documentation example and local-only design

AI Generated Review Areas

List files, modules, prompts, or flows engineers should review first.

  • Service logic for task creation and completion
  • Any future persistence layer replacing the in-memory store
  • Any future auth or public deployment changes

Final Signoff

All four signoffs are required before the handoff packet is considered complete. If a reviewer is unavailable, record the blocker in Risks And Limitations instead of checking the box.
