feat(import): add Mermaid stateDiagram importer for typed lifecycle IR#388samiksha-shreya wants to merge 1 commit into
Conversation
Mermaid state diagrams are a common starting point, but there was no path from one into Archify's typed IR, so authors retyped the topology by hand. Adds `archify import state <input.mmd> [output.json]`, backed by a self-contained parser in archify/importers/state.mjs. No new runtime dependency: geometry and text measurement reuse the repo's own renderers/shared/geometry.mjs and text-fit.mjs so the importer cannot drift from the renderer. [*] is a pseudo-state, so it becomes the kind of the state it touches rather than an invented unnamed box. Terminal states default to `neutral`: `--> [*]` says that the lifecycle ended, not how it ended. Nothing reads "Failed"/"Done" or guard text to guess an outcome; `success` and `failure` are reachable only through an explicit --outcome id=kind flag, which is author intent rather than inference. `waiting` and `external` are never emitted, because Mermaid has no construct that means them. Composite states are rejected loudly rather than flattened: flattening would have to invent transitions between an inner region and the composite's siblings. Concurrency, fork/join, styling directives, self-transitions, and diagrams above the band capacity of 11 states are rejected the same way, each with a code, line, evidence, and executable supportedFixes. Importer input is treated as untrusted: quotes, `<script>`, `</text>`, entity codes, and a `-->` inside a quoted description are asserted inert in the IR and escaped in the artifact, whose SVG is re-parsed with saxes. Control characters are rejected by name rather than silently stripped. Tests: 27 new, written before the implementation and exercised through the CLI seam by validating every emitted IR with `archify validate lifecycle`. Valid fixtures additionally assert composition.summary.warnings === 0, so a layout regression that merely avoids hard errors still fails. Suite 773 tests / 745 pass / 0 fail / 28 skipped (the 28 are the ARCHIFY_CHROME browser tests: skipped, not passed). archify.zip rebuilt under Node 22.

Reject malformed --outcome values.
value.split('=') accepts Published=success=extra because it ignores fields after the second field. This applies the success override although the value does not match state=success|failure.
Author: require exactly one = and an exact success or failure value.
Proposed fix
- const [state, kind] = value.split('=');
- if (!state || !['success', 'failure'].includes(kind)) fail(`--outcome expects state=success|failure, received "${value}".`);
+ const match = /^([^=]+)=(success|failure)$/.exec(value);
+ if (!match) fail(`--outcome expects state=success|failure, received "${value}".`);
+ const [, state, kind] = match;As per path instructions, the affected contract is the documented --outcome state=success|failure CLI path.

Write the import output atomically.
commandImport calls node:fs’s fs.writeFileSync(output, ir) directly. This can truncate the existing Lifecycle IR before the write completes. A write failure can leave the last valid output empty or partial, contrary to the documented contract. Write ir to a temporary file in the destination directory, then rename it to output after success.

Guard labels on [*] transitions are parsed and then discarded.
parseTransition validates and returns label for [*] --> X : text and X --> [*] : text. Lines 351-360 use only to/from and drop label. The label never reaches the IR and no diagnostic is emitted.
This contradicts the module contract on lines 10-12 and the authored-content rule in the skill documentation: unsupported constructs must be rejected, not dropped.
Pick one of two remedies. Reject the construct with a named diagnostic, or carry the text onto the state as context. Rejection is the smaller change and keeps the contract exact.
🐛 Proposed fix: reject the dropped label

Reject ineffective outcome overrides. resolveModel accepts any existing state, but kindFor returns active for non-terminal states and returns decision before checking outcomes for <<choice>> states. Therefore the CLI can succeed while --outcome Review=failure or --outcome Reviewing=failure has no effect. Reject non-terminal and choice targets before placement, while preserving the unknown-state diagnostic.

Run and inspect the documented render step.
The documented workflow runs archify render lifecycle after import and validation. This test stops after validation, so a renderer or final-artifact failure for release-train.state.mmd can pass. Run the render command, assert success, extract the SVG from the HTML output, and parse it with the existing XML helpers.
