Either policy can use a +bounded controller, live observation/action calls, or both. Switching strategy +never grants permission to change an exact case. + +Resolve only missing details that affect correctness or authority: + +- The executable or build to exercise, with its actual path and identity. +- Cases or goal, supplied context, expected outcomes, and initial state. +- Permitted files, hosts, accounts, repositories, and other effects. +- Desired media format and constraints. Honor an explicit format; use GIF for + an unspecified terminal animation and MP4 when the caller requests video. + +Default to condensed presentation, with static pauses shortened. Honor explicit +real-time requests and retain the original capture timestamps. Keep timing +adjustments in the recording metadata, not repeated on-screen labels. + +A request such as "upload an attachment" is not permission to choose an +arbitrary account or publish to the current repository. Ask for the missing +target/authorization before performing a write. Prefer synthetic data and +isolated configuration. + +Command discovery is a separate case property. A case may provide the command +and test its use, or explicitly require finding it. Do not silently turn a +known-command case into a discoverability test. + +Preserve the non-secret original request alongside normalized cases. Never copy +credentials into the contract or recording; use approved secret references or +report blocked if the requested literal recording would disclose them. Use +[the run contract](references/run-contract.md); unsupported or ambiguous +requirements must be clarified or marked blocked, not discarded. + +## 2. Establish readiness and authorization + +Read [the preflight module](internal/cli-exercise-preflight/SKILL.md). +It checks dependencies. If setup is needed, propose commands using the pinned +requirements, obtain caller approval, and recheck afterward. + +Installation approval and permission to modify test resources are independent. +Record the executable path, version/revision, checksum, accepted case contract, +and approved effect scope before starting the subject. + +Use a secure private workspace outside the repository. Do not put recordings, +credentials, runtime caches, or operator configuration in this skill directory. +No secret values belong in the contract or a tool request. + +## 3. Load the appropriate internal flow + +- Supplied cases: [record exact cases](internal/cli-exercise-exact/SKILL.md). +- Broad goals: [explore a goal](internal/cli-exercise-explore/SKILL.md). + +Both use [the shared run module](internal/cli-exercise-run/SKILL.md). +It provides real terminal observation, input, controller execution, recording, +and bounded process ownership.

Inspect every overview page, its 10-second duration, case +coverage, fidelity label, outcome styling, invocation display, and progress at +holds and chapter boundaries. Confirm no overlay appears in an unannotated cut. +Inspect every distinct visual state for a privacy or +transient-state claim. The helper saves identical pixel images once and retains +their frame, timestamp, source-state, and revision mappings in the manifest. +Use those mappings to locate repeated appearances rather than expecting a +separate PNG for each frame. +State actual coverage.

The bridge validates the required + Tuistory methods, including `clickAt`, and the pinned PTY handle used for + process-group cleanup before reporting readiness. Both the bridge and target + use isolated environments. No separate Node probe or global + daemon is used. The Go fixture has a four-second deadline, and cleanup has a + separate five-second bound. +- Go font checks load and draw with the actual TTF/OTF/TTC file and verify equal + advances for all printable ASCII characters. + This is not a promise of coverage for every Unicode glyph. +- MP4 checks encode two real frames with `libx264` and `yuv420p`, exercise looped + PNG input for overview pages, and check the `drawbox`, `color`, and `overlay` + filters used for whole-video progress. GIF checks use per-frame `palettegen`, + `paletteuse`, and the GIF encoder so rendering need not + buffer a whole live session. ffprobe must decode the outputs + and confirm their dimensions, codec, and frame count. Request only formats + needed by the case, and do not use a receipt to claim unprobed formats. + Normal session delivery needs MP4 chapter intermediates, including a single + case or a GIF-only final session. Probe MP4 and any requested GIF format; + only standalone per-invocation GIF clips can omit MP4 capability. + A native sample also exercises `select`, passthrough frame timing, and RGB + decoding for inspection of the actual encoded media. + +Known font locations are checked on macOS, Linux, and Windows. `fc-match` is not +required. Missing fonts or unsupported native PTY libraries are reported, not +replaced with another recorder or guessed compatible configuration. Node 26.7, +Go 1.27, and ffmpeg 9 are development examples, not a blanket platform +compatibility claim. The actual capability probes decide readiness. + +## Receipts + +With `--output`, stdout contains status, the saved report path, problem +descriptions, and the next permitted step. +Load the saved JSON when tool paths, installation details, or full diagnostics +are needed. Do not load helper source during normal execution; inspect it only +when debugging the helper itself. + +A ready receipt has `schemaVersion: 1`, `status: "ready"`, `manifestSha256`, +and these `tools` entries: + +```json +{ + "node": {"path": "/absolute/node", "version": "observed version"}, + "tuistory": {"moduleRoot": "/absolute/node_modules", "version": "0.11.0"}, + "ffmpeg": {"path": "/absolute/ffmpeg", "version": "observed version"}, + "ffprobe": {"path": "/absolute/ffprobe", "version": "observed version"}, + "font": {"path": "/absolute/font.ttf", "family": "observed family"} +} +``` + +Checks and itemized failures accompany the receipt. Missing pinned packages can +produce `needs-install`; missing system tools, unusable native capabilities, or +unverified safety conditions produce `blocked`. Failed receipts contain only +the tool details that could be observed. Argument failures may not +have tool observations at all. Exit codes are 0 for ready, 1 for needs-install, +and 2 for blocked or invalid input. + +`manifestSha256` hashes `scripts/package.json` then `scripts/package-lock.json`. +For each, the hash input is its base +UTF-8 filename, a zero byte, its byte length as an eight-byte big-endian integer, +and its exact contents. Executable/font hashes are additional provenance, not an +OS trust or permission mechanism. + +## Agent-led setup + +Use the appropriate package manager for setup, keeping it separate from +capability checking: + +1. Use the selected platform and pinned manifests to propose exact commands. + State the versions, trusted sources, destination, and any global changes. +2. Ask the caller to approve those commands before downloading or installing. +3. Execute the approved setup, then rerun `preflight check` with the actual paths. + +For Tuistory, use the bundled `scripts/package.json` and `package-lock.json`. +A typical setup copies them into a new private dependency directory outside the +skill and repository and runs `npm ci` against the public registry. Keep optional +native packages enabled and lifecycle scripts disabled. Do not replace an +existing installation or change the pinned versions implicitly. + +Go, Node, FFmpeg, fonts, and platform-specific repairs may need different setup +commands. The agent determines those from the environment rather than a custom +installation framework. Preserve any partial-install facts and do not claim +readiness until the real capability checks pass. + +Terminal execution requires Unix process-group cleanup and ownership checks. +Platforms where these are not implemented remain blocked even if their +dependencies are installed; installing more packages does not resolve that +limitation. + +## Offline regression tests + +```sh +GOTOOLCHAIN=local GOPROXY=off GOSUMDB=off \ + -C .github/skills/cli-exercise/tool test -mod=readonly ./internal/preflight +``` + +The constructor/CLI and run-behavior tables use test-owned files and process +fakes.

Its response may still show the preceding screen. Wait for the +needed condition or observe again before deciding the next interaction. + +Pure waits and annotations do not authorize extra input: + +```json +{"op":"wait","until":{"screenContains":"Ready"},"timeoutMs":5000} +{"op":"wait","milliseconds":1000,"timeoutMs":1500} +{"op":"note","chapter":"INPUT","text":"Enter the supplied value."} +``` + +These are three separate requests, not one JSON document. Conditions combine +literal `screenContains`, `questionPrefix`, and `selected` fields with AND. +Regular expressions and generated predicates are not accepted. + +Canonical actions and timing are defined in [the run contract](run-contract.md). +Keys are supported names, printable ASCII, or modifier chords such as +`["ctrl","c"]`. Separate keypresses must be separate actions, not a chord array. +Ctrl letters are case-insensitive. Shift letters produce their uppercase +characters, optionally with Alt. Enter, Tab, Backspace, and Escape support +combinations of Ctrl, Alt, and Shift. Other keys support Alt only. +Meta, additional modifiers on Ctrl letters, and other chords whose modifiers +Tuistory ignores are rejected before input. +Semantic selection requires a unique label in a supported arrow-marked line +menu. Checkbox toggles verify their requested boolean state. Unsupported or +ambiguous selectors return an error rather than guessing. Mouse clicks use +zero-based cells and require supported SGR mouse reporting from the target. +Resizing emits a fresh terminal snapshot even if the target prints nothing. + +Every live and controller action uses the same fidelity and denial gates. +Denials also cover primitives generated by semantic navigation, newlines, and +ordinary terminal key aliases. An unobservable required selection fails closed. +Equivalent key spellings, letter case under Ctrl or Shift, and modifier order +are normalized for denial matching and physical delivery. Exact-step comparisons +and recorded contract values stay unchanged. +If an exact action fails after delivering part of its input, the run stops as +blocked rather than replaying the already delivered prefix. + +Load [the controller reference](controllers.md) only when using a controller. +An uncovered controller state can pause without restarting the terminal. +Strategy changes do not authorize changing supplied steps. + +Natural target exit closes the runtime automatically. `finish` or `shutdown` +while the target is live interrupts it and produces a blocked run, not a +successful exit. Once closed, `observe`, `finish`, and `shutdown` return the +saved result without starting another process. +Stopping a run cancels pending terminal operations before waiting for action +completion, so an outstanding acknowledgement cannot prevent cleanup. +Cleanup tracks the actual PTY process group, not just its leader's exit. +The adapter waits for the native TERM/KILL escalation and verifies that the +group is gone before acknowledging closure. Go also retains the group identity +for forced cleanup if the adapter fails or its close operation is cancelled. + +## Environment and privacy + +Only explicitly approved `environment.pass` names enter the Go owner and cross +the adapter's anonymous in-memory pipe. Their values never belong in contracts, +external client requests, arguments, or +logs. HOME, profiles, configuration, caches, and temporary roots are isolated. +There is no automatic account lookup or operator configuration inheritance. + +Tuistory 0.11 fixes `TERM=xterm-truecolor` and `COLORTERM=truecolor`; conflicting +reviewed values are rejected. Protocol replies describe real cell geometry, +cursor, and configured colors, not invented pixel-window dimensions. + +Declared secrets are checked in source documents, input, raw output, and visible +states, including split output and invisible OSC data. Operator-specific paths +outside declared locations are rejected. Rejected text is not saved and later +presented as successfully redacted output. + +A possible credential prefix may temporarily defer evidence and return +`privacyPending:true` with only the last safe observation. The top-level revision +still describes the active UI. Do not infer an exploratory action from withheld +text. Prefer a bounded wait or already-authorized canonical input through the +same gate. Contracts and controller sources cannot contain actual secrets, +including secrets split across literal steps. + +These checks and the authorization record are not an OS sandbox. The selected +program still runs with the operator's OS privileges. + +## Evidence layout + +All generated data lives under the contract's workspace: + +```text +contract.json +runtime.json +capture/ + contract.json + states.jsonl + events.jsonl + raw.jsonl + controllers/ +result.json +artifacts/ +``` + +Each state record contains `t` in monotonic seconds, `revision`, +`alternateScreen`, and `data` from the real Tuistory terminal. Each event records +`t`, its `type`, and the execution `mode` (`ai`, `controller`, or `host`). +Go decodes shared terminal types for observations and rendering while preserving +the original `data` JSON, including fields the current reader does not know. +Input events retain the requested action and its actual preceding observation. +Annotations use `type: "note"` with `chapter` and `text` fields. +The `ai` execution mode identifies the live-client interface; it does not attest +that a request came from a model rather than a scripted client. + +`result.json` records `caseId`, `command`, `contractSha256`, `durationSeconds`, +`exitCode`, `exitSignal`, `captureStatus`, `caseStatus`, and expectation results. +It also records `stepsCompleted`, `expectedSteps`, `actionsCompleted`, +`stopReason`, `interrupted`, `captureError`, `actionError`, `cleanupError`, +`cleanupDurationSeconds`, and `finalObservation`. `originalContract` points to +the exact-byte copy at `capture/contract.json`. Cleanup time is excluded from +capture duration. + +Runtime `startedAt` and `finishedAt` metadata lets session assembly check actual +execution chronology. Preserve it without edits. Nonchronological, overlapping, +or reused captures cannot be assembled as a valid sequential session. Legacy +captures lacking these timestamps remain readable only with an explicit +`execution order unverified` warning, not a claim of verified chronology. + +Capture is `complete` only after a normal, fully captured exit and successful +cleanup. Actual nonzero exit codes remain unchanged. Interruptions, signals, +limits, partial input, or capture failures produce `failed` capture status and +retain the evidence. The runtime bounds captured and pending data to 64 MiB; +exhausting it is an explicit capture failure. +The adapter also bounds its unread event backlog to 64 events. Overflow reports +an incomplete capture while keeping response delivery available for cleanup; +it does not silently discard output and report success. + +Case statuses are `passed`, `failed`, `blocked`, and `observed`. Missing required evidence, +unsupported expectations, and unfinished exact steps cannot pass. + +The evidence helper reads this layout without contacting the target service. +It writes media and JSON evidence under `artifacts/`, with optional HTML for +interactive review. +Cleanup closes only the runtime's owned process groups and transport. It cannot +contain a program that deliberately daemonizes into a separate session. +Preserve the contract and evidence; never delete the user's repository or +unrelated files. + +## Offline evidence rendering + +For the normal final deliverable, including a single case, use +`evidence --session ` with [a recording session](recording-sessions.md): + +```sh + --skill-root evidence \ + --session --preflight +``` + +Each case covers one behavior, with its preparation, one exercise invocation, +and immediate validation captured before the next case. Assembly preserves +actual order, not a rearrangement of previously batched phases. The annotated +session includes a task-specific overview and continuous whole-session progress. +Every readable overview page lasts 10 seconds; long lists gain pages rather +than losing cases. Fidelity is derived from exercise contracts as `Exact run`, +`Exploration`, or `Mixed run`, and recorded with overview timing in rendered +session metadata. No new session input fields are needed. + +The low-level form +` --skill-root evidence --run-dir --preflight ` +remains available for per-invocation clips. It is not the normal path to a final +session video with overview and whole-session progress. +Go rasterizes the recorded terminal cells and captions from the explicit +OpenType fonts, then streams frames to FFmpeg. It writes a new private rendering directory +rather than replacing prior evidence. Only media is delivered by default; raw +capture, JSON reports, and inspection files remain internal evidence. +Add `--html` to also generate a self-contained HTML report. Without it, neither +standalone nor session renders create HTML, including per-chapter reports. +Use `--inspection all` when the claim +requires every source state; the default extracts representative samples. + +To make an additional presentation from the same capture, supply `--format gif` +or `--format mp4` (repeat for both), and/or `--timing realtime|condensed`. +When timing is unspecified in the contract, presentation defaults to condensed. +Explicit contract timing is preserved unless `--timing` overrides it. No separate +approval is required for condensed presentation: + +```sh + --skill-root evidence \ + --session --preflight \ + --format mp4 --timing condensed +``` + +Keep each run's manifest `verification` reference for manual expectations, or +the `--verification` argument when rendering a per-invocation clip. +The selected formats must have passed preflight. These flags affect only the +new rendering, not the command, assertions, original contract, or raw capture. +The report records a separate `presentation` object and retains the original +contract hash. Without overrides, output follows the recorded contract, using +condensed timing only when that field is omitted. `--timing-authorization` may +optionally record the caller's request for a condensed companion. + +Annotated session output labels preparation in purple and running in blue. +Validation has visible result text, green for passed expectations and red for +failed ones; unknown, blocked, and observed results must not look passed. +Show the immutable recorded executable and arguments above the captured +terminal output, not as invented keystrokes or a second shell execution. +The lower panel explains the run in plain language rather than `Command: ...`. +A thin progress line spans overview pages, reading holds, and chapter boundaries +without restarting. Explicit unannotated real-time output keeps all of these +additions off. See [session presentation](recording-sessions.md#present-the-session). + +The helper uses the same assertion evaluator as the live Go owner, applying it +to the actual exit code and final +recorded terminal of a complete invocation. Interrupted runs, failed captures, +and incomplete exact cases remain blocked; partial final-screen text or a +termination signal does not establish a product failure. Unsupported expectation +types are explicitly blocked. `--verification ` can supplement only manual +expectations with this shape: + +```json +{ + "contractSha256": "", + "results": [ + { + "id": "", + "status": "passed", + "reason": "What the independent observation established.", + "evidence": ["verification/readback.json"] + } + ] +} +``` + +Evidence references must identify existing files inside the private workspace. +This records the agent's verification; it is not cryptographic attestation. +It cannot override an automatic failure or make unfinished exact steps pass. +The helper preserves case outcome when rendering fails and reports the latter +separately. Optional HTML embeds media and requires no playback server. + +Only requested and preflight-probed formats are rendered. GIF-only output does +not require the MP4 encoder for a standalone per-invocation clip; session +assembly does require MP4 chapter intermediates, even for a GIF-only final +deliverable. `rendering.mediaDetails` records each media file's +hash, dimensions, decoded frame count, actual duration, and reported frame rate. +GIF timing has centisecond granularity; the timeline's duration is not an exact +timing assertion for that format. +Final output is retained even when it arrives between frame ticks. Real-time +reports separate `captureDurationSeconds` from encoded timeline duration and +disclose any frame-quantization tail as `endHoldSeconds`. + +`inspection/manifest.json` binds media hashes to image hashes. Identical rendered +pixels, including dimensions, are stored once under `inspection/images/`. +This compares actual pixels, not just terminal text; cursor, color, selection, +and caption changes remain distinct. + +The manifest's `rendered` entries map inspected video frame ranges to an image, +capture time, source-state index, revision, and annotation time. Repeated +appearances retain separate entries even when they share an image. +`sourceStates` maps every captured state to its image, time, revision, and +alternate-screen flag when `--inspection all` is selected. The original +capture journals and video frames are unchanged. The existing `sampled` mode +still provides sampled coverage; deduplication does not turn it into an +exhaustive review. + +`encodedSamples` identifies first, middle, and final frames decoded from each +actual output under `inspection/encoded//`. Inspect those too rather +than judging codec quality from source images alone. +Rendering rejects frames above 64 megapixels, font sizes above 512 points, and +timelines above one million frames rather than allocating unbounded resources. +This leaves the original case result and capture intact. +Visual review remains pending in the original generated report. After actually +inspecting the images, preserve a separate `visual-review.json` beside it: + +```json +{ + "contractSha256": "", + "manifestSha256": "", + "status": "passed", + "coverage": "First, final, and all supplied validation transitions.", + "images": ["inspection/images/image-000000.png"], + "findings": [] +} +``` + +Use `passed`, `failed`, or `blocked` to describe that visual review only. List +actual inspected paths; do not claim every state from representative samples. +Keep the report's at-rendering status and point to this completed receipt at +handoff. The receipt records the reviewing agent's observations, not automated +proof of privacy or rendering fidelity. diff --git a/.github/skills/cli-exercise/scripts/package-lock.json
