+ * step-runner — the two substrate seams for graph-owned stepwise execution
+ * (plan 2026-06-04-001, KTD-2 / U2).
+ *
+ * This module exposes exactly two capabilities that the workflow-graph executor
+ * (U3/U5) will drive — it does NOT wire itself into any graph path here:
+ *
+ * - {@link runTaskStep} — run exactly step `i` of a task inside its
+ * session/worktree and return the outcome plus
+ * the per-step `baselineSha` / `checkpointId`
+ * that a later RETHINK needs.
+ * - {@link resetStepToBaseline} — the RETHINK mechanics, extracted verbatim
+ * from `executor.ts`'s `fn_review_step` RETHINK
+ * block (`git reset --hard ` + session
+ * rewind via `navigateTree`/`branchWithSummary`
+ * fallback + `store.updateStep(..., "pending")`),
+ * plus a defensive blast-radius guard (KTD-2).
+ *
+ * Both are parameterized via an explicit `deps` object (the DI style used by
+ * `hold-release.ts` / `merge-trait.ts`) so they stay unit-testable without real
+ * git, real sessions, or a real `StepSessionExecutor`. Production callers (U3/U5)
+ * pass thin adapters over the existing engine machinery; the legacy in-session
+ * `fn_review_step` path is untouched and keeps its own copy's behavior — this
+ * extraction is the single implementation the executor's RETHINK block now
+ * delegates to (see `TaskExecutor.applyStepRethink`).

+ * decrements a per-instance budget seeded from `config.maxReworkCycles`
+ * (default 3, defensively clamped to ≤10); exhaustion emits the
+ * `outcome:rework-exhausted` outcome from the foreach node;
+ * - threads the active instance under the reserved `foreach:active` context key

+ * they operate on, clearing it on instance exit;
+ * - honors the abort signal between nodes (existing posture).

- updateStep source:'graph': dependency-order done guard, audit-loud suppression, auto-reinit bypass; projection-first ordering
- runGraphTaskStep: per-step step-session physics pinned for graph-owned runs (closes U3 interim)
- step-parsers.ts registry (step-headings byte-identical move + json-steps), store delegates via registry

+/**
+ * Step-parser registry (U12, KTD-12).
+ *
+ * Step parsing becomes a graph-native node (`parse-steps`): a registry resolves
+ * a parser id to an implementation that reads an artifact's content and yields a
+ * canonical step list. Built-ins:
+ * - `step-headings` — the extracted `parseStepsFromPrompt` logic (the
+ * `### Step N:` regex + `(depends: …)` annotation from U1); legacy callers
+ * in `store.ts` delegate to this exact function (byte-identical parity).
+ * - `json-steps` — a structured `[{ name, depends? }]` JSON document for
+ * workflows that plan in JSON.
+ *
+ * The registry mirrors the trait-registry posture: built-ins are protected from
+ * override, and plugins register under namespaced ids
+ * (`plugin::`). This module is engine-free and must NOT
+ * import `store.ts` (store imports the extracted parser from here).
+ *
+ * Parsers may throw on malformed input; callers (the engine's parse-steps
+ * handler) map a throw to a routable `outcome:parse-error`.

+ * `outcome:approve|revise|rethink|unavailable` edges route on:
+ *

+ * - REVISE → `value: "revise"` (rework edge, no reset — revise in place)
+ * - RETHINK → `value: "rethink"` (rework edge whose traversal resets, U5 foreach)
+ * - UNAVAILABLE → bounded retry (cap {@link STEP_REVIEW_UNAVAILABLE_RETRY_CAP});
+ * still unavailable → `value: "unavailable"`
+ *
+ * The verdict + reworkCount are persisted via the foreach sub-walk: the handler
+ * writes the latest verdict back onto the active context so the sub-walk's

+ * - string → text input
+ * - text → textarea
+ *
+ * Editing is per-field, save-on-commit (blur for inputs, change for
+ * toggles/selects/chips/radio). Each save calls `onSave({ [fieldId]: value })`;
+ * on a 400 the caller surfaces the typed rejection through `error`, which this

+/**
+ * Code-node runner (U14, KTD-15).
+ *
+ * Executes a workflow `code` node: arbitrary user-authored TypeScript that runs
+ * as a general computation escape hatch (derive a field, compute routing data,
+ * call an internal API). The source is:
+ *
+ * 1. compiled in-memory with esbuild (TS → ESM, no bundling, no resolution);
+ * 2. written to a temp module in the OS temp dir;
+ * 3. executed in a CHILD `node` PROCESS with `cwd = task worktree`, a minimal
+ * env, and the serialized `ctx` delivered on stdin;
+ * 4. the child default-exports `async (ctx) => result`; its JSON result is
+ * written to stdout between sentinels and parsed back here.
+ *
+ * Harness contract:
+ * ctx = {
+ * task: { id, title, description, column, steps, customFields },
+ * context: ,
+ * artifacts: { read(key): string | undefined }, // pre-read, plain object
+ * instance?: ,
+ * }
+ * result = { outcome?, value?, contextPatch?, customFields? }
+ * - outcome string → routes outcome:; absent → success
+ * - contextPatch → merged into the walk context
+ * - customFields → written through the U11 validation authority by the
+ * handler wiring (NOT here — the runner has no store)
+ *
+ * Failure posture (fail-closed, audited): throw / timeout / non-zero exit /
+ * compile error → a thrown {@link CodeNodeError} carrying captured stderr
+ * (capped). The handler maps it to a `failure` node outcome with the error in
+ * the audit/node result. The runner never gets a store handle, engine
+ * internals, or the step-list write path (KTD-15 boundaries).
+ *

+ * Plugin step-parser adapter (U12, KTD-12).
+ *
+ * Bridges plugin-contributed step parsers into core's {@link StepParserRegistry},
+ * mirroring {@link import("./plugin-trait-adapter.js")} for traits. Plugins
+ * register parsers under namespaced ids (`plugin::`) so they
+ * can never collide with or override the built-ins (`step-headings`,
+ * `json-steps`) — the registry enforces builtin-namespace protection and the
+ * `plugin:` id shape on registration.
+ *
+ * Contract (KTD-12): a plugin parser is `(artifactContent) => { steps }`. The
+ * adapter wraps each contributed parser so that:
+ * - a throw is re-thrown as a {@link PluginParserError} (fail-closed): the
+ * engine's `parse-steps` handler maps any throw to a routable
+ * `outcome:parse-error` (audited) — never a crash;
+ * - an unavailable parser (the plugin provides no usable `parse` function) is
+ * likewise a fail-closed throw;
+ * - a result that is not a `{ steps: [...] }` object is rejected (fail-closed).
+ *
+ * Timeout posture (documented deviation): the core registry's `parse` is
+ * synchronous (the engine handler calls it inline), so a plugin parser cannot be
+ * pre-empted mid-call by a timer the way an async runtime hook (trait adapter)
+ * can. Plugin parsers run with the same trust tier as project-local script steps
+ * (KTD-15 framing). The adapter therefore enforces the timeout BUDGET it is
+ * given by measuring wall time AROUND the synchronous call and failing closed
+ * (throw → parse-error) when the parser overran — the result is discarded so a
+ * slow parser can never silently feed a stale/partial step list. A truly
+ * runaway synchronous parser is a plugin bug bounded by the same posture as a
+ * runaway script step.

+/**
+ * WorkflowFieldsPanel — the workflow editor's custom-field authoring surface
+ * (U13 / KTD-14). Sibling to {@link WorkflowColumnPanel}: lives alongside the
+ * canvas in {@link WorkflowNodeEditor} and mutates the IR's `fields` array
+ * through the same state/save flow.
+ *
+ * Each field has: an immutable kebab-case `id` (editing it is remove+add
+ * semantics — the panel warns rather than silently re-keying values), a display
+ * `name`, a `type` (string|text|number|boolean|enum|multi-enum|date|url), a
+ * `required` toggle, a typed `default`, an options editor (value/label/color)
+ * for the enum kinds, and `render` controls (placement, widget, badge).
+ *
+ * Card-placed fields show a live badge preview reusing TaskCard's
+ * `.card-field-badge` classes so the authored chip matches the board exactly.
+ *
+ * Core validation (unique ids, options-required-for-enums, render whitelists)
+ * runs server-side at save and surfaces through the editor's existing inline
+ * mechanism — this panel only does light client guards and renders the
+ * resulting message via the shared error band.
