/**
 * CC config key `workflowSizeGuideline`: an ADVISORY size guideline for LLM-authored workflows
 * (small/medium/large/unrestricted), injected into the Workflow tool's prompt/description. It is
 * guidance, NOT a cap — the hard ceiling stays `WorkflowLimits.maxAgents`.
 *
 * RB-339 (2026-07-30, A 案) — REBASELINED on CC 2.1.220 (语料 ../cc-decoded/pretty220.js). The
 * module was anchored to 2.1.206 and had drifted on four points; all four are corrected here and the
 * old "verbatim" claims (which were not true of the two sentence builders) are replaced with what
 * each function actually is:
 *  1. DEFAULT. CC's `_Td = "medium"` (:455529) with `Oft` (:455538) returning `{ size: "medium",
 *     isDefault: true }` whenever the setting is absent or not a member of the enum. sema defaulted
 *     to "unrestricted" (= inject nothing), so an unconfigured deployment got NO guideline at all.
 *     Behavior narrowing, declared: an unconfigured task now carries the medium section.
 *  2. TWO-ARM SECTION. CC's `TTd(size, isDefault)` (:455514) has a DEFAULT arm ("This session has the
 *     default …" + the "/config" escape sentence) and an EXPLICIT arm ("A workflow size guideline is
 *     configured for this session:" with no escape sentence). sema had a single hand-written form.
 *  3. CHANGE NOTICE. CC's `ETd` (:455523) — both arms differed from sema's wording.
 *  4. Normalization. CC's `Msn` (:455494) is a MEMBERSHIP test returning `undefined` for a non-member
 *     (which then falls to the medium default); sema mapped every unknown value to "unrestricted",
 *     i.e. a typo in the setting silently disabled the guideline. Now `undefined`, per CC.
 *
 * Still-current 220 anchors: `rLs` enum (:455532) / `oko` caps (:455533) / `bTd` describe (:455507) /
 * `STd` not-a-hard-limit sentence (:455511) / `Sj_` display label (:455497). Those five ARE verbatim.
 *
 * Injection site: CC appends the section to BOTH `prompt()` and `description()` of the Workflow tool
 * (`oLs`, :455548 — returns "" for "unrestricted", else "\n\n" + the sentence). Snapshot semantics:
 * CC memoizes the SESSION-START value (`Nsn`) so the card is stable within a session; a mid-session
 * /config change reaches the model via a `workflow_size_guideline_change` attachment (`vTd`, :455555)
 * rendered with `ETd`. sema equivalence: the card is built once per mount (`createRunWorkflowTool`) =
 * per-task snapshot — same stability property.
 *
 * Mid-session change lane (SHIPPED — the module no longer ships static injection only): CC's `vTd`
 * (:455555) recomputes the RESOLVED guideline each turn, recovers the last announced one (its own
 * previous attachment, falling back to the session-start snapshot) and emits a
 * `workflow_size_guideline_change` attachment rendered with `ETd` on inequality. sema's equivalent
 * lives at the run loop's turn-boundary steerer (`runtask.ts`, alongside the structurally identical
 * date_change / instructions_change lanes): the leg's resolved guideline is the baseline, the live
 * `RunnerDeps.workflowLimits` read is the current value, and {@link workflowSizeGuidelineChangeNotice}
 * is the copy. Comparison is on the RESOLVED coordinate on both sides, CC-exact — `vTd` compares
 * `Oft(...).size` against `Nsn(...).size`, so a deployment writing down the value already in force by
 * default is not a change. Two lane properties are sema's own and deliberate: the frame is
 * continuation-gated (an advisory retune must never revive a finished run), and only the
 * `WorkflowLimits` channel is watched — the direct-construction `RunWorkflowToolDeps.sizeGuideline` is
 * a per-mount pin the runner never sets.
