Paste it verbatim into every spawn and every resume. Directives decay across resumes, and each dropped one costs a human turn. When you catch yourself restating an instruction, append the line before you act (principle-encode-lessons-in-structure). -- `overview.md` is the durable PR and issue DB. Append. Never rewrite wholesale per event. -- `units.tsv` has one row per unit: id, track, state, branch, PR, head SHA, brief path. Update rows in place. -- `frontier.json` is the computed merge frontier, per Stack safety. -- `ledger.tsv` is the verification ledger, per Verification. -- `inbox/` holds completion pointers. `gates.md` parks human gates (question, options, default on no answer). -- `decisions.tsv` is the trail via the show-me-your-work skill. -- `status.md` is derived from `units.tsv` and `ledger.tsv` at each drain, never hand-maintained. Regenerate it from the tables instead of narrating events into it. - -#### The brief - -Your prompts to agents are your only product, and a sloppy brief compounds into slop across the whole tree. Every spawn carries all of it. A field you cannot fill is a unit you have not scoped yet. - -``` -GOAL one sentence, the outcome, executable by a stranger with no chat access -SCOPE paths this unit may write; paths it may not; its exclusive worktree or branch -CONTEXT pointers to files and PRs; upstream reports pasted in full when this unit - depends on them, because workers cannot see siblings -ACCEPTANCE checkable criteria, one per line -VERIFY exact commands or the control-skill path, plus known gotchas -TIMEBOX rough cap on runtime; on expiry, return partial findings and stop rather than run on -FORBIDDEN no PR retargets or merges, no rebase, no force-push, no fixes outside scope, - plus unit-specific bans -REPORT status, branch, head SHA, PRs, verdict, what you actually ran, deviations, - suggested follow-ups -STANDING -``` - -Size the brief to the unit. A one-command unit gets the template collapsed to a paragraph that still names goal, scope, the verify command, and the report shape. A 4KB scaffold around a two-line edit costs more to write and obey than the edit. Initial spawns may reference the standing-orders file by store path. Paste it verbatim on every resume. - -A sub-coordinator brief adds its track boundary and unit list, its spawn budget with the isolated workspace default and the local exception list, the drain protocol, and the rollup format (per child: name, status, PR, head SHA, verdict, one line, plus track status and frontier delta). - -A dependency is a context relay, not just ordering. Undeclared upstream context makes the worker guess. Missing fields are a refuse-to-spawn condition. Audit one sampled worker brief per sub-coordinator per wave, concurrently with the wave it samples, never as a gate in front of it. A failing brief stops that track and fixes the sub-coordinator's instructions, not just the worker, because brief quality decays late in a run. Never resume-chain a brief. Respawn fresh with consolidated scope. - -#### Steps - -1. **Frame.** State the done predicate as something countable ("all 126 units merged, each ledger-verified `unit-test-verified` or better"). Quantify scope: units, rough effort, expected stacks, and the wall-clock budget. If one agent could finish inside that budget, stop here and run Autonomous run instead. Collapsing must not depend on another document being present. It means do the work directly in this session, plain workers where they help, verification inline, landing as you go, and none of the store, register, or pilot machinery below. Schedule landing against the budget. By roughly 70% of it, stop spawning and land what is verified. Name the tracks per project. A contested decomposition or one-way door goes through the arena skill before the pilot. Present the framing once. Reversible prep proceeds without waiting. -2. **Install the runtime.** Run `orch init`. Open the trail via the show-me-your-work skill, write the standing orders before any spawn, and seed `frontier.json` from existing PRs with `orch frontier set --repo `, adding `--forge origin` when the forge is Origin. -3. **Pilot.** Push one unit through the whole path: brief, worker, verification, stack entry, ledger row, merge. The pilot exists to falsify the brief template, the verify recipe, and the unit size while that costs one agent instead of fifty. Fix the contract from pilot evidence before any fan-out. Scale the pilot to the unit. On programs of near-identical cheap units, the first unit is the pilot, run as a normal unit with its verify command inline, and fan-out starts the moment it lands. The dedicated pilot pipeline (separate verifier agent, audit gate) is for expensive or novel unit shapes, not for clone-units where a serialized pilot has nothing to falsify. -4. **Scale.** Spawn a rolling window of workers up to the in-flight cap, refilling as children finish. Blocking batches pay the slowest child of every batch. Spawn track sub-coordinators only past the one-drain threshold in Roles. Recompute ready work after each drain. Relay upstream reports into downstream briefs. Keep sibling communication upward only. The sampled brief audit runs alongside the wave it samples and stops the next refill on failure, not the current one. -5. **Drain.** Run the queue discipline below at every drain point. -6. **Land.** Landing is continuous, never a terminal phase. Integration starts with the first verified unit and runs alongside the remaining waves. On heavy repos the stacker is a standing role from wave one, integrating as units verify. On repos where local git is cheap, the coordinator lands verified units itself per Roles. Keep the frontier green before upper-stack work. Stack safety governs. Advance `frontier.json` only on merge or reported new head SHAs. -7. **Close.** Drain the final inbox, reconcile every spawned agent to a terminal row (done, abandoned, zombie-reconciled), confirm the predicate on the real artifact, confirm every landed PR has a verdict for its current head SHA, audit the trail per show-me-your-work including its cross-model review, encode recurring corrections into `preferences.md` or the brief template. Leave the store intact. It is the postmortem. - -#### Queue and drain - -- On a completion notification, run `orch inbox push [--report PATH]` and return to what you were doing. Never deep-review inline. A completion that needs review becomes a verifier unit. Never review a diff inside a drain. -- Drain in batches at four points: the end of a critical section, a track rollup, a frontier watcher wake (arm it via the `schedule` tool, with a long heartbeat fallback), and before a human report. Begin each batch with `orch inbox drain`. Arrivals during a drain wait for the next one. -- Critical sections you finish first: authoring a brief, a stack operation, a conflict decision, writing a gate, updating ledger or frontier. -- Each drain classifies every pointer (landed, needs-verify, failed, zombie, noise), writes the resulting rows through `orch unit add`, `orch unit set`, and `orch ledger record`, runs `orch status`, then spawns the next wave in one message. -- Account for every spawned child at its track's rollup: arrived, respawned, or its scope explicitly absorbed. Silently redoing a missing child's work hides both the wasted spend and the coverage gap its result existed to close. -- A drain turn ends with the three lines from `orch status`: counts against the states, what changed, gates open. Detail lives in `status.md`. The full reply contract applies at checkpoints and close. - -#### Stack safety - -- The frontier is a computed object, never narrative. Recompute `frontier.json` after every merge and stack mutation: ordered PR list, branch names, head SHAs, a generation number, the lowest unmerged PR. The command walks the PR base chain through the checkout's current branch, so chain order and PR states come from the forge. It uses `gh` by default. Pass `--forge origin` when the program resolved the forge to Origin. Head SHAs come from local branch refs, so resolve it from the stacker's clone. A branch with no PR errors rather than guessing. -- Exactly one stacker per stack may mutate topology (chain rebases, force-pushes, base retargets, merges), serialized within its stack. Record the holder in the standing orders. Chain rebases run in a worktree on this machine (`Workspace: "branch"`). A rebase at this scale can take the laptop down, so run one at a time. -- Workers never rebase and never retarget or merge PRs. Babysitters follow `playbooks/babysit.md`, one per stack, scoped to one immutable frontier generation. They report conflicts to the stacker rather than rebasing. -- PR closes and retargets go through the stacker only. Closing a base PR orphans every chain above it. Merges and stack surgery are units with briefs like any other. -- One retro watcher follows merged PRs for reverts, post-merge CI breaks, and orphaned follow-ups. - -#### Verification - -Scale verification to the unit. When VERIFY is a single cheap command, the worker runs it and reports the output, and the coordinator spot-checks receipts. A dedicated verifier agent (on a different model tier than the worker) is for units whose verification is expensive, judgment-laden, or high-blast-radius. A verifier agent whose entire product would be rerunning one command is ceremony, not verification. - -Write ledger rows with `orch ledger record`. Check the current PR and head SHA with `orch ledger check`. `ledger.tsv`, one row per verdict, keyed by PR number plus head SHA: `live-ui-verified | unit-test-verified | type-check-only | verifier-blocked | verifier-failed`. CI green is an input to a verdict, not a verdict. Behavioral work needs better than `type-check-only`. `verifier-blocked` is not a pass. Respawn when the environment heals. `verifier-failed` gets a fix unit, not a re-verify. A worker may self-report. A verifier overrides it on the same key. A new head SHA voids the row, so re-verify after restack. The ledger answers "was this verified", not memory and not the transcript. - -A unit is not done until its output is externalized the moment it lands, never batched to the end of the run. A worker pushes its branch, a verifier writes its ledger row, receipts land in the store. Work that exists only on one VM when that VM dies was never done. - -#### Liveness and failure - -- Never resume an agent to check on it. A resume restarts an idle agent. Probe read-only: the ledger, `units.tsv`, `gh`, pushed branches, and `manage_subagents` (`Action: "list"`). Transcript mtime is not liveness. -- A silent death gets a synthetic postmortem row in the inbox (unit, failure mode, last evidence, options). Replan on evidence as it arrives. Never wait for full quiescence. -- Retry by mode: cap-hit or oom, respawn with smaller scope. Network-drop, retry as-is. Tool-error, retry on a different model. Unknown, retry once. Two retries, then abandon the unit and replan around it. -- A zombie that returns hours late reconciles against the current frontier and ledger before anything is accepted. Salvage unique findings through a fresh unit, never a blind merge. -- When continued spawning would produce garbage tree-wide (bad upstream output, broken acceptance, dead infra), write a stop line at the top of the standing orders, let in-flight work finish, fix the cause, clear it. -- Bound your own infra retries the same way you bound a child's. After a few consecutive tool aborts, stop retrying. Write a terminal handoff to durable state (what is done, where it lives, the exact command to resume) and end the run. -- After an Antigravity restart: in-flight subagents are dead, pushed branches and PRs are not. Re-read the standing orders and `units.tsv`, recompute the frontier, reattach work by PR and branch rather than agent id, respawn one sub-coordinator per track from its stored brief plus current state, drain, resume. The dead session's store lock clears itself on the next write. `orch` replaces a lock whose holder pid is gone. - -#### Escalation - -Reaches the human, batched into the status page rather than per item: irreversible actions (force-push to shared branches, deploys, deletions, closing someone else's PR), genuine product or preference calls no experiment settles, a standing order that contradicts observed reality, a program-level dead end that survived a replan. Park each as a `gates.md` entry before asking, and route work around it. - -Never reaches the human: frontier nudges, rebase mechanics, retries, CI flake triage, review-thread triage, format fixes, scope the brief already forbids (refuse and continue), and "should I keep going". When in doubt, act and log. - -Mid-run discoveries fix only what blocks the frontier. Everything else parks in follow-ups. At this fan-out a small scope leak multiplies into PRs nobody asked for. - -**Reply:** at checkpoints and close: the predicate and the count against it from `units.tsv` and `ledger.tsv`, tracks and what each landed, the frontier (PR list plus SHAs), verdicts summary, what was abandoned and why, gates awaiting the human (the only asks), the store path, and the trail path. Numbers from the tables, not narrative. Include PR links. +**Reply:** what landed against the goal, each PR's live state and verdict with its link, what was dropped and why, and the decisions waiting on the user. diff --git a/skills/poteto-mode/scripts/orch/orch.test.ts b/skills/poteto-mode/scripts/orch/orch.test.ts deleted file mode 100644 index be8edd5..0000000 --- a/skills/poteto-mode/scripts/orch/orch.test.ts +++ /dev/null @@ -1,795 +0,0 @@ -import { afterEach, describe, expect, it } from "bun:test"; -import { - chmod, - mkdir, - mkdtemp, - readFile, - readdir, - rm, - writeFile, -} from "node:fs/promises"; -import { realpathSync } from "node:fs"; -import { tmpdir } from "node:os"; -import { join } from "node:path"; -import { - NotFoundError, - UserError, - openStore, - parseVerdict, - type Forge, - type OpenStoreOptions, - type Store, -} from "./store.ts"; - -const SCRIPT = join(import.meta.dir, "orch.ts"); -const directories: string[] = []; -const handles: Store[] = []; - -interface RunResult { - readonly code: number; - readonly stdout: string; - readonly stderr: string; -} - -async function makeDirectory(): Promise { - const directory = await mkdtemp(join(tmpdir(), "orch-test-")); - directories.push(directory); - return directory; -} - -function useStore( - directory: string, - options?: OpenStoreOptions -): Store { - const store = openStore(directory, options); - handles.push(store); - return store; -} - -async function initializedStore(): Promise<{ - readonly directory: string; - readonly store: Store; -}> { - const directory = await makeDirectory(); - const store = useStore(directory); - await store.init(); - return { directory, store }; -} - -function git({ - args, - repo, -}: { - args: readonly string[]; - repo: string; -}): string { - const result = Bun.spawnSync(["git", "-C", repo, ...args]); - if (result.exitCode !== 0) { - throw new Error( - `git ${args.join(" ")} failed: ${result.stderr.toString()}` - ); - } - return result.stdout.toString().trim(); -} - -async function makeGitStack(directory: string): Promise<{ - readonly repo: string; - readonly mergedSha: string; - readonly closedSha: string; - readonly openSha: string; - readonly draftSha: string; -}> { - const repo = join(directory, "repo"); - await mkdir(repo); - git({ repo, args: ["init", "--initial-branch=main"] }); - git({ repo, args: ["config", "user.name", "Orch Test"] }); - git({ repo, args: ["config", "user.email", "orch@example.com"] }); - await writeFile(join(repo, "main.txt"), "main\n"); - git({ repo, args: ["add", "."] }); - git({ repo, args: ["commit", "-m", "main"] }); - - const branches = [ - "stack/merged", - "stack/closed", - "stack/open", - "stack/draft", - ]; - for (const [index, branch] of branches.entries()) { - git({ repo, args: ["checkout", "-b", branch] }); - await writeFile(join(repo, `stack-${index}.txt`), `${branch}\n`); - git({ repo, args: ["add", "."] }); - git({ repo, args: ["commit", "-m", branch] }); - } - git({ repo, args: ["checkout", "stack/open"] }); - - return { - repo, - mergedSha: git({ repo, args: ["rev-parse", "stack/merged"] }), - closedSha: git({ repo, args: ["rev-parse", "stack/closed"] }), - openSha: git({ repo, args: ["rev-parse", "stack/open"] }), - draftSha: git({ repo, args: ["rev-parse", "stack/draft"] }), - }; -} - -type FixtureState = "open" | "draft" | "merged" | "closed"; - -const FORGE_FIXTURES: Readonly< - Record< - Forge, - { - readonly fields: string; - readonly row: (pr: { - number: number; - state: FixtureState; - head: string; - base: string; - }) => Record; - } - > -> = { - gh: { - fields: "number,state,headRefName,baseRefName", - row: ({ number, state, head, base }) => ({ - number, - state: state === "draft" ?

Check it with the config that its authors say it passes, and pass that config as `--against-config` unless it has the spec's file name. One mapping labels both models, so label states and steps from variables that both have. A label that reads a variable that only the copy has must test `"name" in v` first, and label the spec's states another way. When a model describes code, tie every variable and action to code that a reviewer can open, and take its name from that code. Make each action one indivisible step in the code. Put the file and line of the code that checks each condition of an action in a comment on that condition, as in `\* pay.ts:120`. +`scripts/statechart.ts` is TypeScript, so run it with a runtime that can execute TypeScript. -## Spec to chart +The first run installs TLC and Java with mise and needs the network. -1. Choose the chart's states. When the reader cares about something that a label would hide, put it in the label, such as "Paying, charged twice" when the screen still says "Paying" after a second charge. Start with few states. Split a state when the split separates two bugs, or when the reader must see a step that leaves the label the same, such as a request that reads a count, because the chart does not draw such a step. -2. Write each rule that the reader agrees to as one invariant, with the reader's sentence as its comment. A rule can be about any state in the model: what a screen shows, what a request returns, a stored value, or a message between parts. When the model describes code, the rule also names the code that can change that state. If the model has no variable for what a rule is about, add the variable. Do not drop the rule. For a rule that applies once everything settles, define `Settled == ~ENABLED System`, where `System` is the disjunction of the actions that happen without the reader. For a rule that applies at a narrower point, such as after each request finishes, write a predicate for that point and make the rule hold where it is true. For a goal that the system must be able to reach, write a rule that says the goal never happens, and pass that rule with `--expect-broken`. The path that breaks it is then a way to the goal. The chart still draws the goal as a state that breaks a rule, and `stories.md` tells it as a bug, so name each goal rule in the hand-off. Report each other broken rule as a bug. Never weaken a rule to make the chart pass. -3. Run `from-spec`, then fill in the mapping file it writes. Put the labels in `state` and `step`. When the chart must separate what the reader does from what happens around the reader, list the reader's actions in `readerActions` by action name. Leave the list empty when every action counts the same. When the overview is too large to read, add `--cover`. The overview then keeps only the shortest path to each settled state, plus every bug path, and the command lists what it leaves out. When two bugs end in the same state for different reasons, add `cause` and make it name each reason. To color the states by what the reader cares about, such as "Order shipped", return that group from `group`. The legend names the groups, and in the PNG a state that breaks a rule is red in place of its group color. -4. If there is a proposed fix, model it and pass that model as `--fixed`. -5. Render each chart with `--png` and look at every PNG. Check that each numbered path reads in order. If a label reads like code, fix `state` or `step` and run the command again. -6. When the model describes code, replay each bug's story against the real code, as a test or a live repro, one step per model action. Drive only entry points that a user, a client, or another part of the system reaches, and assert only what they can observe. A test that asserts a flag that it sets, or that searches the source text, proves nothing. When a run proves part of the story and reading the code proves the rest, say which part each proves. When the test copies code that it cannot import, give the commit and line range of the copy, and list what the copy leaves out. If a bug does not reproduce, assume the model is wrong until you show otherwise. Fix the model, not the rule. For a design with no code yet, the TLC trace is the evidence, and the hand-off must say so. +## Write the spec -## Chart to spec +- Write each rule that the reader agrees to as an INVARIANT. A rule can be about a screen, a result, a stored value, or a message. If the model has no variable for a rule, add the variable. Never weaken a rule to make it hold. +- Write `Next` as a disjunction of the actions, such as `YouPressPlay \/ YouPressStop`. If you do not, TLC names every step `Next`. +- A state with no step out breaks `NoDeadlock`, also when it is a correct end state. When an INVARIANT or a PROPERTY already has that name, the rule is `CHECK_DEADLOCK`. Add to `Next` an action that is true only in the end states and changes nothing, such as `Done == phase \in {"paid", "failed"} /\ UNCHANGED vars`, and give it a label in `step()`. -1. Draw the chart that the reader agrees to. Use one region for each part that changes independently, such as a device's connection and the job that the device runs. Add one `%% never` line per rule, with the reader's sentence. Draw an event that stops or restarts a part, such as "the app closes" or "the process restarts", as an edge to the state that comes next. Run `render CHART.mmd` to get a PNG of the chart for the reader. -2. Run `from-chart`. If a rule breaks, the agreed chart has a design bug. Take the bug to the people who agreed to the chart. -3. Add the real code's guards and variables to the spec that `from-chart` wrote, and run `from-chart` again. For each difference it prints, ask the reader whether the code is wrong or the chart needs a correction. +## Pick the chart + +You do the work that needs judgment: the words on each state and arrow, the phases and their colors, the title, and the report to the reader. Put your work in a view module, and give it with `--view`. + +To show the reader's words, the view exports `state(vars)`. The value that `state()` returns picks the form: + +- A string gives a flat chart: `export const state = (v) => (v.paid ? "Paid" : "Paying");` +- An array gives parent states: `export const state = (v) => v.main.split(".");` +- An object gives one parallel region for each key: `export const state = (v) => ({ Playback: v.playback, Volume: v.volume });` + +Label each state with what the reader can see or cares about, such as "Paying" or "Lease held, write pending". Keep variable names out of labels. In `vars`, a TLA+ sequence is an object with keys from 1, so `v.pc[1]` is `pc[1]`. A set is an array. + +The view can also export `step(action, from, to)`. It gets the TLC action name and the values before and after the step, and it returns the label of the arrow. Write each step label as the user sees it happen, such as "you press play" or "the connect fails". Do not name the code or the TLA+ action. Two actions that end the same in the chart get the same label, so that they share one arrow. + +When a step can occur only in some conditions, end its label with the condition in brackets, in the reader's words, such as `you press play [while the file loads]`. In a regions chart, the command writes the condition on the other regions on the arrow, in the words of their labels, such as `[when Offline]`. Your brackets replace it, and two arrows from one state can then look the same. So in a regions chart, do not write brackets for a condition on another region. When a value that no label shows decides where a step goes, name the result in the label, such as "the roster read fails". + +The view can also export these: + +- `group(vars)` returns the name of a phase. Each chart state gets the color of its group. When the model states behind one chart state are in different groups, that state gets no color. +- `colors` gives each group name a color class. +- `title` is a string that the chart shows at the top. + +The command calls `state()` and `group()` at most once for each model state, and `step()` at most once for each step. The chart and the report both use those answers. So make each function depend only on its arguments. + +The chart does not draw a step that stays in one label. Split a label when the reader must see such a step. + +Aim for about 20 arrows or fewer, because a busier chart is hard to read. First return coarser labels from `state()`. Give one label to values that act the same, and leave out a detail that the reader does not need, such as a call in flight whose return changes nothing. Keep each state of a bug path, and keep each mark. When a merge changes a `breaks` state to `mayBreak`, it hides where a rule breaks. Do not merge two states that break different rules, because the reader then cannot see which rule breaks where. If the chart is still too busy, return `null` from `step()` for the steps that the reader does not need, such as a reset that every state has, or a step whose arrow repeats what other arrows show. Obey these rules when you hide steps: + +- Keep each chart state reachable by arrows from a start state. +- Keep at least one arrow out of each chart state that has a step out in the model. +- Hide all the steps of an arrow, or none of them. When you hide only some, its condition gets narrower. +- In the hand-off, say which steps the chart hides. + +## Read the report + +- In the chart, a state that breaks a rule has the class `breaks`. When only some model states behind it break the rule, it has the class `mayBreak`. The Legend names the rules of each mark. When two rules break, it names both on one mark, so say in the hand-off which state breaks which rule. In a regions chart, a state gets a mark when each combination of region states that includes it can break a rule. When a combination can break a rule and none of its states has a mark, each state in that combination gets a mark. +- TLC goes past a state that breaks a rule, so the chart shows the states after a bug. +- Because TLC goes past bugs, a model with no limit on its states can run without end. Keep the constants small, or add a CONSTRAINT. +- With a VIEW or a SYMMETRY, TLC counts states that it treats as the same as one state, and the chart draws that one state. An arrow can lead to it rather than to the state that the step reaches, and the report says so. +- TLC checks the rules in each state past a CONSTRAINT or an ACTION_CONSTRAINT, but it does not explore that state or check it for deadlock. When TLC's shortest path for a rule ends in such a state, the chart draws that state, and the report gives that path. The chart does not draw the other states past the bound. A deadlock in such a state does not show. TLC also checks the rules after each step that an ACTION_CONSTRAINT excludes, also when it reaches the next state another way. When TLC's shortest path for a rule ends with such a step, the chart draws that step. +- The command checks the rules with TLC on the config as written, with one worker. When a rule breaks, the command removes that rule and runs TLC again, until no rule breaks. After the first break, each run stops at 100,000 distinct states, so that a large model does not run without end. When a run reaches that bound or stops on an error, the report lists the rules that it did not check under "Rules not checked", and the chart does not mark them. A rule that is not checked can hold or break. To check it, remove the rules that break from the config, or make the model smaller. The bound adds a module that changes TLC's order of the variables, so for a property TLC can find a different counterexample than a run without the bound. +- `tlc.out` is what TLC printed on the config as written. When the chart does not show the bug path of a rule that breaks, `tlc-RULE.out` is what TLC printed for the run that found it. When TLC repeats its first warning, plain TLC prints it twice, but `tlc.out` shows it once, because TLC leaves the second copy out of the output that this command reads. That happens only when Java runs with `-XX:+UseParallelGC`, since otherwise TLC's first warning is its advice to pass that flag, which it prints once. + +## Show the chart + +Show `chart.mmd` to the user as a `mermaid` code block. The chart has a budget of 500 states, counted by TLC on the config as written. Above that, the chart draws only the paths to the rules that break, and when no rule breaks, the command writes no `chart.mmd`. It still checks each rule, and the report gives the state count and each bug path. To see the whole graph, make the model smaller. + +Render charts with Pele. When the user asks for an image, or a chart is too large to read as text, follow `references/render.md`. Do not use a different renderer unless the user asks for it. ## Hand off -Give the PNG and the Mermaid source of each chart to the person who must decide. Add one line per bug with the rule it breaks, its steps as the chart numbers them, whether it reproduced, and whether the proposed fix fixes it. A broken PROPERTY has no path on the chart, so give the TLC counterexample that `stories.md` names for it. With `--against`, also say whether the spec already lists it: in the configs that `stories.md` names, in the spec's notes on what the model leaves out, or not at all. When the model describes code, do not report that a rule holds while the command lists conditions with no file and line. Take every count you quote from `summary.json`. Attach `stories.md` and the command that regenerates everything. Say what the model leaves out. +Give each chart and its Mermaid text to the person who must decide. Add one line for each bug: the rule, the reader's sentence for that rule, and the path as the report numbers it. Say what the model leaves out. Give the command that makes the files again, with a new `--out` folder. + +When the model describes code, replay each bug path against the real code, as a test or a live repro, one step for each action.

Install Pele once, outside the repo. Write each SVG next to its `.mmd` file, with the same name. The API is at https://pele.run/api. Pass `{ limit: 1_000_000, outputLimit: 8_000_000, maxEdges: 10_000 }` as the options of `render`. Pele's defaults are smaller than a chart of 500 states can be. When Pele throws a `PeleError`, show the user the Mermaid text and the error. + +## Colors + +Pele ignores Mermaid `theme` and `themeVariables`. Set its `--pele-*` CSS variables on `.pele`. https://pele.run/theming lists them. The command gives each state the color class of its group, such as `class sN teal`. It marks each bad state with `class sN breaks` or `class sN mayBreak`, each state on the shortest path to a bug with `class sN bugPath`, and each state that a PROPERTY counterexample repeats forever with `class sN repeats`. Pele puts these classes on the state's node. Color the classes with CSS. + +The `.mmd` file has a `classDef` line for `breaks` and for `mayBreak`, so that any Mermaid viewer shows the bug marks. It has no `classDef` for the group colors, `bugPath`, or `repeats`. Pele writes each `classDef` color as a `style` attribute on the node, and a `style` attribute wins over a normal CSS rule. So the rules for the marks below use `!important`. Without it, a dark theme keeps the light mark colors. A bug mark sets the fill and the text, and `bugPath` and `repeats` set the border. Put the mark rules after the group colors, so that a mark shows over the group color. + +These colors are suggestions. They are the colors of the old skill.

A composite stands for every state in it. A "%% when ID, ID" or "%% when not ID, ID" line - right after a transition is its guard, and the transition's label must end with the guard's - words in [ ]. The region takes the transition only while each other region that the line names - is in one of the states that it names, or with not, while none is. A transition with no label is - its own action.

An edge with no label counts only when no labeled edge joins - the same two states.`; - -const RENDER = `render CHART.mmd - Draws one chart as a PNG. It does not run TLC, so the chart can come from from-spec, from - from-chart, or from a person. - - --theme NAME The colors of the PNG: light, dark, or classic.

The - command makes the folder when it does not exist. - - Exit codes - 0 The command wrote the PNG. - 2 The command cannot finish: a bad argument, a chart that it cannot read, a renderer that it - cannot install or load, or a PNG that it cannot render or write. It writes no PNG then.`; - -const PNG = `PNG - Pele lays out each chart, and resvg draws it at twice its size. A chart that is more than 100 - million pixels at that size draws smaller, at about 100 million pixels. The first PNG installs - ${PACKAGES.join(" and ")} with npm into a cache folder. The folder is - $XDG_CACHE_HOME/statechart/${CACHE_NAME}, or - ~/.cache/statechart/${CACHE_NAME} when XDG_CACHE_HOME is not set. Delete that folder to - install them again. When npm or the packages fail, the command prints why, exits 2, and writes - no file. - The PNG uses the font that fc-match finds for system-ui. The command measures each label in that - font, so no label goes past its box. When that font is wider than the widths that Pele has built - in, the command makes the wrap width wider by the same amount, so the lines break where the chart - breaks them. Without fc-match, or when resvg cannot read that font, the PNG uses Pele's widths. - Pele puts parallel regions side by side.

The PNG section tells how. - --theme NAME The colors of each PNG: light, dark, or classic. Default: light. It needs - --png. - -h, --help Print this help, and exit 0. - -Output - The command prints whether each rule holds, the chart's counts, and one story per bug. - from-chart also prints the comparison. The command writes these files in the output folder: - chart.mmd The overview. - bug-N.mmd Only the steps of bug N, numbered. Bugs are numbered by fewest reader steps, - then fewest model steps, then rule name, then cause. Bugs that only the - --fixed or --against model has come last. - bug-N-developer.mmd, bug-N-layered.mmd - The path of bug N through the developer's states, when the mapping exports - detail(). The layered chart puts each detail state in a box named by its - state label. A state with a blank detail stays a plain state. - stories.md One entry per bug: the rule, why it breaks, the steps that lead into it, the - shortest path in reader steps, and what the --fixed or --against model does - instead. The rule's sentence is the \\* comment lines above the rule in the - spec, or in a module in its folder that the spec EXTENDS, directly or - through another module. With --fixed or --against, the other spec and its - modules count too, after SPEC.tla and its modules. The entry numbers each - step that changes the state label, each reader action, each step that - changes a variable that the rule reads, and the step into the bug. Between - them, it counts the hidden steps and names each different step once. Above - the steps, a line names up to five different steps that lead into the bug, - most common first, and counts the rest. When more than one step or start - state leads into the bug, the entry says that the path is the shortest that - TLC found. A step leads into the bug when it goes there from a state that - keeps the bug's own rule. That state can already break other rules. "(the - state stays the same)" marks a step on that line that keeps the state's - label and is not on the bug's path. from-spec does not draw such a step. - When TLC names the steps only after the whole next-state action, the entry - cannot count them. Then one line per broken PROPERTY with its sentence, - which comes only from its own spec file, the reader states that repeat - forever, if any, and the TLC output that has its counterexample. - summary.json The counts behind the chart. Each bug has counterexamples, how many model - states end it, each with its own TLC trace; lastSteps, the steps that lead - into it, most common first; and startsHere, whether a start state is in it. - brokenProperties has each broken PROPERTY, its rule sentence, the reader - states that repeat forever as repeats, and its TLC output. mixedStatus - lists the states that break a rule in some cases. chartGroups counts the - drawn states of each group, and mixedGroups lists the states in more than - one group. With --cover, cover lists the states and arrows that the - overview leaves out. With --fixed or --against, uncited has the conditions - with no file and line for each code model. With --against, second.listed - has what each config beside AGREED.tla expects, and each bug has the - configs that list it. - tlc/ The config and the TLC output of each run. When the overview has regions, - from-spec also writes tlc/regions-all.mmd, the regions with every arrow, and - tlc/regions-proof.mmd, every state and step of TLC's graph in one region. - compare-charts.mjs tlc/regions-all.mmd tlc/regions-proof.mmd repeats the - proof. It prints "same" and exits 0, or prints each difference and exits 1. - *.png Each chart as a PNG, with --png. A run without --png deletes them. - -Reading a chart - from-spec draws the overview as two parallel regions when every state reads "context: progress": - the contexts on one side, the progress on the other, both at the same time. It does so only when - that has fewer states, when the regions combine back into exactly every state and step of TLC's - graph, and when each state's color is the worse color of its two region states. Otherwise it puts - the states of one context in a box named context, and prints why. Each state in a box shows only - its progress, and a context with one state stays a plain state. - Regions draw only the arrows of the shortest way to each state, of each bug path, and of the - nearest step with each label. The script checks that these arrows make no step that TLC's graph - does not have. At a step that they make wrongly, it puts back every arrow that the full regions - take there. - An arrow from a box's border leaves from every state in the box. The chart draws it only when - every state in the box takes the step with the same labels to the same state, and no state - outside the box has the box's name. - In regions, a step leaves every region that has it. "[when A or B]" or "[unless A or B]", - whichever is shorter, says which states of the other region the step needs, and a "%% when" or - "%% when not" line under it lists their ids. A loop says the region may also stay. - Other words in [ ] come from the mapping's guard(), and "after N s" from its timer(). An edge - shows guard() words only when every model step behind it has them. In regions, they replace - "when A or B" and "unless A or B". TLC does not check them, and has no clock, so a reviewer - checks them against the code. - Gray states work. Red states break a rule. An orange state breaks a rule in some cases: a model - state under its label breaks a rule, and a path without a bug reaches another one. A white state - is reached only after a bug: every path from the start to its model states passes a state that - breaks a rule, and none of them breaks one. With --fixed, red, orange, and white describe the - fix, and green states are fixed by it or exist only with it. A purple state breaks a rule only - with the fix: today it works, is reached only after a bug, or does not exist. With --against, a - state takes the worse of its two models' colors, red, then orange, then white, and green states - exist only in the spec. - When the mapping exports group(), the fill is the state's group, which the legend names. A chart - state is in a group when all its model states are in it, and a region state when every state - that it is part of is in it. A state in no group, or in more than one, is gray. The legend lists - the groups that the chart draws: first the groups in groupColors, in that order, then the others - from A to Z, and then each status border that the chart uses. groupColors gives a group a light - "#rgb" or "#rrggbb" color. A group with no color takes the next free palette color: light blue, - orange, purple, yellow, teal, tan, then pink. A group cannot have the name of a status, such as - "Breaks a rule". Without group(), the legend shows only the statuses that the chart uses. In the - .mmd file, the status is a thick border of its color, gray for a white state, on top of the group - fill. In a PNG, a red, orange, purple, or white state is a box of that color with a border and - text of its color in place of its group fill, and a fixed state is a green box, so each box shows - one signal. - A thick blue border and numbered labels mark the bug. With group(), and in a PNG, the blue border - marks only the states on the bug's path that work, and the numbered labels show the rest. - Mermaid state diagrams cannot color an edge. - Each bug replays on the other model by its state labels and step words, which are what the - reader sees. The replay takes the bug's own steps. Between them, it also takes the other model's - steps of actions that SPEC.tla's state graph does not have, when they keep the state label, are - not reader actions, and change no variable that the broken rule reads. A bug step that the story - hides must keep the state label on the other model too, unless that model cannot take it. A step - that the reader sees takes a step with the same words between the same two state labels, and - prefers a step of the same action. A hidden step of an action that the other model does not have - is skipped. A step that the reader sees of such an action takes any step to the same shared state - when it changes a shared variable, or else a step with the same words between the same two state - labels. - A label "with the fix, STEP" or "in the spec, STEP" is a step that only the other model takes. On - a bug's path it leaves the state before the first step that the other model shows the reader - differently, and ends where that model goes instead. The story quotes the other model's words - when they differ. "with the fix, STEP cannot happen at step N" or "in the spec, STEP cannot - happen at step N" loops on the state where that model stops the step, on an arrow of its own. On - the overview, the label ends with "of bug M". Outside regions, two states otherwise have at most - one arrow between them. Its lines are the numbered steps, then SPEC.tla's steps, then the other - model's steps, with a blank line between each group. - The other model may have other variables, record fields, and actions. The comparison leaves out a - variable or field that no state of one model has, in its state graph or its traces, and one whose - values never have the same type in the two models. One mapping draws both models, so it may read - only what both have. The command stops when the mapping reads, on a state of the other model, a - variable or field that no state of that model has, or one whose value has a type that SPEC.tla - never has there. It also stops when the mapping lists the fields of such a state, as a spread, - Object.keys, or JSON.stringify does. Test "name" in v before the mapping reads a field that the - other model lacks. The command also stops when a label, guard, group, or cause that the mapping - makes for the other model has the word "undefined" in it. - A chart with another model has the line "%% second model (fix|against): LABEL" right after - stateDiagram-v2. Each chart starts with front matter that keeps Mermaid from shrinking it to the - page or wrapping its labels again. - An edge lists every step that takes it, most common first. Words that the steps share at the - start are written once, as in "you tap Pay or Back". - -Regenerate - List every rule that is known to break with --expect-broken, the goals and the known bugs. Each - run then exits 0 until a rule changes, so one script rebuilds every chart and stops on any change: - set -e - node statechart.mjs from-spec Code.tla --against Agreed.tla --expect-broken NoLostUpload --png - A run that leaves a broken rule out of --expect-broken exits 1, and set -e stops the script there. - -TLC - TLA2TOOLS is the path to tla2tools.jar, and JAVA is the path to the java binary. With only - TLA2TOOLS set, the command runs java from PATH. Otherwise it uses TLC 1.7.4 and Java temurin-25 - from mise, or JAVA when it is set, and installs what is missing with mise. The first install - downloads about 305 MB and needs the network. It checks the checksum of tla2tools.jar. mise runs - in an empty temporary folder, so the mise files around the spec, in a repo, or above TMPDIR do - not apply, do not change, and need no trust. When mise cannot start or fails, the command prints - why, the install command, and how to set TLA2TOOLS and JAVA instead. - When the command starts, it copies its input files, which Exit codes lists. TLC checks the - copies, so an edit during the run does not change what TLC checks. - TLC checks each rule with one worker per CPU. When a rule is broken, TLC checks it again with one - worker, which finds the shortest bug paths, the same on every run. The command then prints how - many times TLC ran and how long that took. - TLC can find that a rule is broken and then stop on an error, such as a Java exception. The - command then keeps the paths that TLC printed, marks the rule broken, and warns that the charts - can miss states that break it. A smaller constant can let TLC finish. - -Exit codes - 0 Every rule holds, or exactly the --expect-broken rules break. from-chart also draws CHART.mmd - back unchanged. - 1 Another rule is broken, an expected rule holds, or the chart that the spec draws is not - CHART.mmd. The output says which. - 2 The command cannot finish: a bad argument, a missing file, a chart or TLC output that it - cannot read, no TLC, a helper script that cannot start, an output folder with files that the - command did not write, an input file whose content changed during the run, a new mapping to - fill in, a mapping that it cannot use, a renderer that --png cannot install or load, or a - chart that --png cannot render. - When a chart does not render, the command keeps the files it wrote and exits 2, whatever the - rules give. Otherwise, exit 2 does not change the output folder, unless the command moved it - aside and cannot put it back. Then the message names the folder's new path. When the command - stops after TLC has run, it keeps the files that it wrote, TLC's output among them, in a - temporary folder, and the message names it. When TLC's state graph is too large to draw, the - command prints whether each rule holds and exits 2, whatever the rules give. It stops TLC as - soon as the graph passes that size. The input files are the spec and config, the --fixed or - --against spec and config, the chart, and the map. Each .tla file in the same folder that an - input .tla file EXTENDS or INSTANCEs is an input file too, and so is each file that an input - .mjs or .js file imports by a relative path. Before --png renders, and again before it writes - the output folder, the command compares the content of each input file with its content at - the start. A save that does not change the content does not stop the run.`; - -export const HELP = { - "": `${usage([...Object.values(USAGE), "node statechart.mjs [from-spec|from-chart|render] --help"])} - -Draws a Mermaid statechart from TLC's state graph of a TLA+ spec.
