Baseline entering Week 2 + +Week 2 should assume the Week 1 control-plane slice is already real: + +- session lifecycle exists, +- a background host process owns each PTY session, +- input, resize, signal, and exit flows work, +- append-only event logging exists, +- `wait --exit` and `wait --idle-ms` exist, +- and the `hello-prompt` and `resize-demo` fixtures already prove the non-rendered path. + +Week 2 should **not** start by reworking the PTY lifecycle unless a concrete replay blocker appears. + +The main goal now is to add the first renderer-backed inspection path: + +1. replay the event log into a reference renderer, +2. expose semantic screen state, +3. support renderer-backed waits, +4. capture deterministic screenshots, +5. and prove those behaviors with screenshots, notes, and short videos. + +## 2. Week 2 goal + +Week 2 should deliver the first inspectable renderer slice of `agent-terminal`. + +At the end of Week 2, an agent should be able to: + +- create a session, +- interact with it, +- ask for a semantic snapshot, +- wait for visible text or visible stability, +- capture a deterministic PNG screenshot, +- and leave behind a proof bundle that includes JSON outputs, screenshots, and a short video. + +Week 2 is **not** the right time to chase native backends, mouse injection, remote control, or full replay export. Those remain later work. + +## 3. Week 2 outcome checklist + +Week 2 is done only when every required checkbox below is complete. + +- [ ] The event-log replay path is strong enough to rebuild visible screen state deterministically. +- [ ] A renderer module root exists behind a narrow backend interface. +- [ ] A lazy `ghostty-web` renderer harness exists. +- [ ] `snapshot` is implemented for at least viewport-scoped JSON output. +- [ ] `snapshot --format text` is implemented. +- [ ] `wait --text` is implemented. +- [ ] `wait --regex` is implemented. +- [ ] `wait --screen-stable-ms` is implemented. +- [ ] `screenshot` is implemented. +- [ ] Built-in render profiles exist for `reference-dark` and `reference-light`. +- [ ] Snapshot and screenshot artifacts are linked to the replayed event sequence. +- [ ] A basic artifact manifest exists for snapshot and screenshot outputs. +- [ ] `doctor` verifies browser / renderer / screenshot viability at least at a smoke-test level. +- [ ] At least one renderer-focused dogfood bundle exists with JSON outputs, snapshots, screenshots, notes, and a short video. +- [ ] The carried-forward Week 1 proof gap is closed by adding a real screen recording / video artifact to the control-plane proof story. + +## 4. Scope boundaries for Week 2 + +### In scope + +- replay correctness needed for renderer-backed inspection, +- renderer adapter interface, +- `ghostty-web` harness boot and replay, +- semantic snapshots, +- renderer-backed wait modes, +- deterministic screenshots, +- render profiles, +- snapshot / screenshot manifest entries, +- and proof bundles with screenshots and videos. + +### Explicitly out of scope + +- `record export --format asciicast`, +- `record export --format webm`, +- native renderer adapters, +- mouse input, +- remote hosts, +- MCP wrappers, +- and cross-platform parity polishing beyond basic smoke coverage. + +Those are important, but they should not dilute the Week 2 renderer slice. + +## 5. Recommended implementation strategy + +I would build Week 2 in four stacked pieces: + +1. **Replay foundation** — ensure the event log contains enough information and sequencing discipline for deterministic renderer catch-up. +2. **Renderer harness** — add the backend interface, the lazy browser boot path, and profile resolution. +3. **Semantic inspection** — implement `snapshot` and renderer-backed `wait` modes. +4. **Visual proof** — implement `screenshot`, manifest entries, `doctor` smoke checks, and the first renderer-focused proof bundles. + +That sequence keeps the implementation aligned with the broader design docs: + +- the architecture doc makes replay and lazy renderer startup foundational, +- the rendering doc treats semantic and visual artifacts as replay products, +- the CLI contract requires machine-usable outputs, +- and the dogfooding doc requires screenshots and videos as evidence rather than unsupported textual claims. + +## 6. Day-by-day plan + +### Day 1 — replay foundation and renderer contracts + +### Implementation checklist + +- [ ] Add `src/renderer/` module roots. +- [ ] Add a narrow `renderer/backend.ts` contract. +- [ ] Add replay input and replay state types shared by host and renderer code. +- [ ] Audit the event log against replay needs and document any missing fields or invariants. +- [ ] Tighten replay-critical assertions around event ordering and terminal dimensions. +- [ ] Add sequence bookkeeping so render-related operations can ask for “replay through latest seq”. +- [ ] Define render-profile types and the initial built-in profile registry. + +### Checkpoint checklist + +- [ ] A renderer backend can be constructed from a replay input shape even if the browser harness is still stubbed. +- [ ] Event ordering assumptions are asserted explicitly rather than implied. +- [ ] Unit tests cover any new replay or profile schemas. + +### Dogfooding gate + +Use the existing control-plane path and produce a brief engineering note proving that the replay input can be derived from a real Week 1 session. + +Required artifacts: + +- [ ] one saved event log from a real session, +- [ ] one small notes file describing how replay state is derived, +- [ ] one screenshot of the terminal command flow that produced the sample session, +- [ ] one short terminal video showing the sample create → interact → inspect flow. + +### Day 2 — lazy renderer harness and profile boot + +### Implementation checklist + +- [ ] Add the `ghostty-web` harness under `src/renderer/ghosttyWeb/`. +- [ ] Add browser bootstrap code for a local-only harness. +- [ ] Implement lazy renderer startup on the first render-related request. +- [ ] Add `reference-dark` and `reference-light` built-in profiles. +- [ ] Pin deterministic visual defaults needed for Week 2 screenshots. +- [ ] Add host-side renderer lifecycle wiring so the renderer can be created, reused, and disposed. +- [ ] Add one restart path so a failed renderer can be re-created from the event log. + +### Checkpoint checklist + +- [ ] First renderer-related command starts the browser harness lazily. +- [ ] The harness can replay a real session through the latest sequence number. +- [ ] Profile lookup succeeds for both built-in profiles and fails clearly for invalid names. + +### Dogfooding gate + +Run a narrow harness smoke test against a real session. + +Required artifacts: + +- [ ] one screenshot of the local renderer harness page or equivalent visible proof, +- [ ] one short video showing the renderer boot path, +- [ ] one notes file confirming that the harness stayed local-only and did not require external navigation, +- [ ] one JSON artifact or debug dump showing the renderer replayed through the expected sequence number. + +### Day 3 — semantic snapshots and renderer-backed waits + +### Implementation checklist + +- [ ] Implement `snapshot`. +- [ ] Support viewport-scoped JSON output first. +- [ ] Add `snapshot --format text`. +- [ ] Implement `wait --text`. +- [ ] Implement `wait --regex`. +- [ ] Implement `wait --screen-stable-ms`. +- [ ] Return machine-usable metadata linking snapshots and waits to capture sequence and visible-screen summary. +- [ ] Add structured errors for renderer startup and replay failures. + +### Checkpoint checklist + +- [ ] `snapshot` returns cursor, rows/cols, alt-screen flag if available, and visible lines. +- [ ] `snapshot --format text` is materially lighter-weight than the structured form. +- [ ] `wait --text` and `wait --regex` operate on visible rendered state rather than raw event-log string matching. +- [ ] `wait --screen-stable-ms` is based on visible-screen stability rather than PTY idleness. +- [ ] Integration tests cover both match and timeout cases. + +### Dogfooding gate + +Use a fixture that visibly transitions from `Loading` to `Ready`, or add one if needed. + +Required artifacts: + +- [ ] one snapshot JSON captured during `Loading`, +- [ ] one snapshot JSON captured during `Ready`, +- [ ] one text-format snapshot, +- [ ] one screenshot at the matched `Ready` state, +- [ ] one short video showing the wait condition resolving at the correct moment, +- [ ] notes describing whether the snapshot, wait result, and screenshot all tell the same story. + +### Day 4 — deterministic screenshots and artifact manifest + +### Implementation checklist + +- [ ] Implement `screenshot`. +- [ ] Capture deterministic PNGs from the reference renderer. +- [ ] Record screenshot metadata including profile, captured sequence, and dimensions. +- [ ] Add basic manifest entries for `snapshot` and `screenshot` artifacts. +- [ ] Ensure artifact paths are stable and written atomically. +- [ ] Add failure handling for invalid render profiles and failed browser capture. +- [ ] Teach `doctor` to verify browser availability, renderer startup, and screenshot viability at a smoke-test level. + +### Checkpoint checklist + +- [ ] The same session state under the same profile yields stable screenshot dimensions. +- [ ] Screenshots are clearly linked to the replayed sequence number. +- [ ] `reference-dark` and `reference-light` both work. +- [ ] `doctor` reports renderer-related failures structurally. +- [ ] Tests cover screenshot creation and at least one `doctor` failure path. + +### Dogfooding gate + +Use `resize-demo` and `color-grid` style scenarios. + +Required artifacts: + +- [ ] one `reference-dark` screenshot, +- [ ] one `reference-light` screenshot, +- [ ] one resize-before screenshot, +- [ ] one resize-after screenshot, +- [ ] one short resize video, +- [ ] one notes file calling out clipping, wrapping, cursor, or palette issues if any are observed, +- [ ] one manifest excerpt or saved manifest file showing the screenshot entries. + +### Day 5 — renderer proof bundles and CI smoke coverage + +### Implementation checklist + +- [ ] Produce the first renderer-focused proof bundle under `dogfood/`. +- [ ] Add or refine fixture coverage for renderer-backed waits and screenshots. +- [ ] Add CI smoke coverage for the renderer-backed snapshot / screenshot path where practical. +- [ ] Document known gaps that remain after Week 2. +- [ ] Close the carried-forward Week 1 artifact gap by attaching a real screen recording / video to the control-plane proof story. + +### Checkpoint checklist + +- [ ] Another team member can review the Week 2 renderer story from the proof bundle alone. +- [ ] The proof bundle contains JSON outputs, snapshots, screenshots, notes, and at least one short video. +- [ ] Known gaps are written down explicitly instead of being implied. + +### Dogfooding gate + +Produce at least one complete renderer-focused scenario bundle. + +Required artifacts: + +- [ ] `create` / `inspect` / `wait` / `snapshot` / `screenshot` JSON outputs, +- [ ] snapshot files, +- [ ] screenshot files, +- [ ] notes, +- [ ] one short screen recording or replay video for the interaction, +- [ ] and one bundle manifest that makes the scenario reviewable offline. + +## 7. Week 2 sign-off checklist + +- [ ] All required implementation and checkpoint checkboxes above are complete. +- [ ] Relevant tests for the implemented Week 2 scope pass. +- [ ] Renderer-backed proof bundles contain screenshots and at least one short video. +- [ ] `doctor` covers renderer smoke checks rather than only baseline environment checks. +- [ ] The remaining gaps after Week 2 are documented explicitly. + +## 8. Week 2 stretch goals + +If the core Week 2 slice lands early, the best stretch goals are: + +- [ ] add `wait --cursor-row/--cursor-col`, +- [ ] add scrollback-scoped snapshot support, +- [ ] add a more explicit renderer-crash recovery test, +- [ ] add a proof-of-feasibility spike for `.cast` export from the existing event log, +- [ ] add a minimal review page or helper for browsing proof bundles locally. + +Stretch goals should not block Week 2 sign-off. + +## 9. Cross-cutting implementation rules for Week 2 + +### Replay before polish + +Do not over-invest in screenshot polish until replay correctness is strong enough that the renderer can reliably rebuild the latest state from the event log. + +### Thin CLI, fat host, narrow renderer interface + +The CLI should remain translation glue. + +The host should continue to own: + +- replay preparation, +- renderer lifecycle, +- capture sequencing, +- and artifact coordination. + +The renderer implementation should stay behind a narrow interface so later native backends do not force a CLI redesign. + +### Defensive programming + +Keep using fail-fast checks aggressively: + +- [ ] assert replay sequence ordering, +- [ ] assert render-profile lookup success, +- [ ] assert snapshot metadata matches the replayed sequence, +- [ ] assert screenshot metadata includes the profile used, +- [ ] assert manifest writes never point at temp files, +- [ ] assert browser harness requests stay local-only. + +## 10. Validation strategy for Week 2 + +Validation should happen in three layers. + +### 10.1 Automated tests + +At a minimum, Week 2 should add: + +- [ ] unit tests for replay/profile/schema logic, +- [ ] integration tests for renderer-backed `wait` and `snapshot`, +- [ ] screenshot smoke tests, +- [ ] `doctor` renderer smoke tests, +- [ ] and a renderer restart / rebuild test if practical. + +### 10.2 Terminal workflow + +Use the repo terminal to: + +- [ ] run Week 2 commands with `--json`, +- [ ] save outputs into `dogfood/-/`, +- [ ] inspect manifest files, +- [ ] inspect snapshot contents, +- [ ] and compare notes against the actual artifacts. + +### 10.3 Visual workflows + +#### Desktop workflow + +Use the desktop agent or an equivalent visual workflow whenever the claim requires human-visible proof. + +Examples: + +- [ ] showing that `wait --text` matched the intended screen, +- [ ] proving that screenshots are visually sane, +- [ ] proving resize redraw behavior under the renderer, +- [ ] or recording a short walkthrough for review. + +For every interaction-heavy checkpoint, capture: + +- [ ] at least one screenshot, +- [ ] and at least one short video. + +#### Browser workflow with `agent-browser` + +Use `agent-browser` or an equivalent browser-grounded tool for: + +- [ ] verifying the local `ghostty-web` harness loads correctly, +- [ ] checking pinned render profiles, +- [ ] verifying the harness remains local-only, +- [ ] and reviewing screenshot outputs when that is easier in a browser context than through raw JSON. + +## 11. Recommended immediate next step + +If implementation starts now, I would begin with the Day 1 replay-contract work and land the narrowest possible renderer-backed slice through: + +- `renderer/backend.ts`, +- lazy `ghostty-web` boot, +- `snapshot`, +- `wait --text`, +- `screenshot`, +- and one renderer-focused dogfood bundle. + +That gives the team a usable inspectability milestone before moving on to replay export, GC, or broader hardening.
