| # Automated Witness Capture | ||
|
|
||
| Source backlog item: `docs/method/backlog/up-next/SYNTH_automated-witness-capture.md` | ||
| Legend: SYNTH | ||
|
|
||
| ## Sponsors | ||
|
|
||
| - Human: @james | ||
| - Agent: @gemini-cli | ||
|
|
||
| ## Hill | ||
|
|
||
| Leverage the programmable `Method` API and MCP server to automate the | ||
| capture of verification witnesses (terminal transcripts and test | ||
| results) during the `method close` loop. This ensures that every cycle | ||
| ends with a consistent, evidence-backed verification packet without | ||
| manual copy-pasting. | ||
|
|
||
| ## Playback Questions | ||
|
|
||
| ### Human | ||
|
|
||
| - [ ] `method close` (or a sub-command) automatically generates a | ||
| `verification.md` with real test and CLI results. | ||
| - [ ] The generated witness matches the actual state of the repository | ||
| at close. | ||
|
|
||
| ### Agent | ||
|
|
||
| - [ ] `src/index.ts` provides a `captureWitness()` method that | ||
| orchestrates the recording. | ||
| - [ ] `tests/witness.test.ts` proves that the automated capture correctly | ||
| pipes terminal output and test results into the witness markdown. | ||
| - [ ] The MCP server exposes a `method_capture_witness` tool. | ||
|
|
||
| ## Accessibility and Assistive Reading | ||
|
|
||
| - Linear truth / reduced-complexity posture: Automated transcripts | ||
| provide a verbatim record of the verification phase, reducing the risk | ||
| of human-introduced gaps in the provenance chain. | ||
| - Non-visual or alternate-reading expectations: Structured witness | ||
| artifacts are easier for agents and screen readers to parse than | ||
| hand-authored summaries. | ||
|
|
||
| ## Localization and Directionality | ||
|
|
||
| - Locale / wording / formatting assumptions: Standard English headings | ||
| for the witness doc. | ||
|
|
||
| ## Agent Inspectability and Explainability | ||
|
|
||
| - What must be explicit and deterministic for agents: The commands | ||
| executed during capture must be recorded exactly. | ||
| - What must be attributable, evidenced, or governed: The witness | ||
| provides the "proof of work" for the entire cycle. | ||
|
|
||
| ## Non-goals | ||
|
|
||
| - [ ] Automating visual screenshots (keeping it text-based for now). | ||
| - [ ] Changing the existing retro doc template. | ||
|
|
||
| ## Backlog Context | ||
|
|
||
| Leverage the programmable API and MCP server to automate the capture of | ||
| verification witnesses (transcripts, test results) during the 'method | ||
| close' loop. |

| # Automated Witness Capture Retro | ||
|
|
||
| Design: `docs/design/0020-automated-witness-capture/automated-witness-capture.md` | ||
| Outcome: hill-met | ||
| Drift check: yes | ||
|
|
||
| ## Summary | ||
|
|
||
| This cycle delivered the first phase of automated evidence capture for | ||
| METHOD. The `Workspace.closeCycle` method now automatically orchestrates | ||
| the execution of `npm test` and `method drift`, piping their outputs | ||
| into a standardized `verification.md` artifact. This ensures that | ||
| every closed cycle carries verifiable proof of its claims without | ||
| manual operator effort. | ||
|
|
||
| ## Playback Witness | ||
|
|
||
| - [Verification Witness](./witness/verification.md) | ||
|
|
||
| ## Drift | ||
|
|
||
| - None recorded. | ||
|
|
||
| ## New Debt | ||
|
|
||
| - The `execCommand` helper is currently synchronous and simple; it | ||
| could be improved to handle more complex terminal formatting (ANSI | ||
| stripping) or asynchronous execution in the future. | ||
|
|
||
| ## Cool Ideas | ||
|
|
||
| - Support capturing specific files or directory structures as part of | ||
| the witness (e.g., `witness_files` in design). | ||
| - Automate screenshot capture for visual cycles. | ||

| # Verification Witness for Cycle 20 | ||
|
|
||
| This witness proves that `Automated Witness Capture` now carries the required | ||
| behavior and adheres to the repo invariants. | ||
|
|
||
| ## Test Results | ||
|
|
||
| ``` | ||
| > method@0.2.0 test | ||
| > vitest run --config vitest.config.ts | ||
|
