 * `init.quick-batch` (#3676, Phase 4 of epic #3344, ADR-1239 "Quick-batch

 * quick id / slug / task directory itself — batch-level id allocation and
 * `BATCH.json` creation is the job of the `quick-batch create` CLI verb
 * (`src/quick-batch-command-router.cts`, wrapping `createBatch` in
 * `src/quick-batch.cts`). This bundle supplies the per-role model profiles,
 * `commit_docs`, the roadmap/planning existence checks `quick-batch.md`'s
 * ROADMAP.md gate needs (same check `cmdInitQuick` runs), the `.planning/quick`
 * directory path, and the `section_manifest` field gating the optional
 * `--research`/`--validate` step fragments — the same `flag:--research`/
 * `flag:--validate` atoms `quick`'s own section manifest already uses
 * (`WHEN_VOCABULARY` is workflow-agnostic; no new atom is needed). `--discuss`/
 * `--full` are rejected by `quick-batch-dispatch.cts`'s `parseQuickBatchArgs`
 * before this init bundle is ever reached, so no `discuss`/`full` flag key is
 * accepted here (unlike `cmdInitQuick`, which still supports both).

 *
 * `state:workstream-active` ground truth: a workstream is active — resolved
 * via `GSD_WORKSTREAM` env, falling back to the stored active-workstream
 * pointer (mirrors `cmdInitProgress`'s own `_resolvedWorkstream` resolution
 * above, the established authoritative source for "is a workstream active"
 * in this file).
 *
 * `other_active_workstreams` hoists the resolver-in-body hazard out of
 * `transition.md`'s `workstream-collision-check` step: that step's body
 * previously re-derived this via an inline `gsd_run query workstream.list
 * --raw` call gated on the identical `if [ -n "$GSD_WORKSTREAM" ]`
 * condition that now backs this section's OWN admission — resolving it here
 * instead reuses `getOtherActiveWorkstreamInventories` (src/workstream-
 * inventory.cts), the SAME primitive `workstream.list` itself calls
 * (`cmdWorkstreamList`, src/workstream.cts), pre-filtered exactly as the
 * step's own prose described (excludes the current workstream and any
 * workstream whose status contains "milestone complete" or "archived",
 * case-insensitively — `isCompletedInventory`), so the step body becomes a
 * pure JSON consumer with no `gsd_run` call of its own.

/**
 * `debug.md`'s dedicated init entry point (#3149; prerequisite for #3128).
 * `debug.md` previously carried NO `gsd_run query init.*` call at all — it made
 * THREE separate round-trips instead: `state.load` (for `commit_docs`,
 * `config.response_language` and `debug_dir`), `resolve-model gsd-debugger
 * --pick model`, and `config-get workflow.tdd_mode --raw`. Because no
 * debug-scoped fact was computed at any entry point, a `when=` atom naming one
 * would have evaluated FALSE forever — ADR-1671's admission gate (2) and the
 * silent-exclusion bug it exists to prevent (`docs/adr/1671-…:122-131`).
 *
 * Every field is resolved through the SAME primitive the call it replaces used,
 * never a second hand-maintained copy (DEFECT.GENERATIVE-FIX):
 *
 * - `commit_docs` — `loadConfig`, the same loader `cmdStateLoad` calls.
 * - `response_language` — NOT read here: `withProjectRoot` already injects it
 *   when configured (#2402), which is also the shape sibling init bundles use.
 *   It is absent, not null, when unset.
 * - `debug_dir` — `planningPaths(cwd).debug`, the SAME expression `cmdStateLoad`
 *   now uses; the `debug` field was added to `PlanningPaths` (#3149) so the
 *   location has one source instead of two kept in sync by hand.
 * - `debugger_model` — `resolveModelInternal`, which IS what `query
 *   resolve-model --pick model` returns (`cmdResolveModel`, src/commands.cts).
 * - `tdd_mode` — the `Boolean(config.tdd_mode)` idiom `cmdInitExecutePhase` and
 *   `cmdInitPlanPhase` already use. `/gsd:debug` has no `--tdd` flag, so the
 *   sibling handlers' `options['tdd'] ||` disjunct is deliberately omitted
 *   rather than carried as a phantom.
 *
 * `state.load` is deliberately NOT narrowed — see the note beside its own
 * `debug_dir` field. This handler is purely additive alongside it.
 *
 * `diagnose` is the one flag `/gsd:debug` already documents. Exposing it as a
 * top-level fact follows `cmdInitUpdate`'s `next_channel` and
 * `cmdInitAutonomous`'s `plan_strategy_converge` precedent, and is what makes
 * the router's flag forwarding observable. No `when=` atom consumes it yet:
 * admission gate (1) — a consuming section of at least 400 bytes — is #3128's
 * to satisfy, and shipping the atom before its section is the same
 * silent-exclusion bug from the other direction.
