/**
 * # grade — honest grading and the fill model
 *
 * Charter: **if you can author it, you can grade it** — a Plan (realized EV through
 * fills), a Wake or Scan (attention efficiency), a View (do agents decide better through
 * it), a regime tag (gated-beats-pooled), a Pod node (the PM's allocations). Grade
 * replays anything authored across recorded sessions under a **named, versioned fill
 * model** and reports honest EV with counterfactuals as syntax (`VS ungated`, `VS null`,
 * `BRACKET`) rather than bespoke scripts. It rests on one **FillModel** seam returning a
 * calibrated `p_fill`, an expected fill price, and a support flag — never a binary fill —
 * and every plan *and* the structural null cross the SAME fill model, so strategies are
 * compared on fills, not on fill assumptions. Every grade stamps its judge; EVs across
 * fill-model versions refuse naive comparison. **Names are data**: `BY name` /
 * `BY lineage` are first-class grade dimensions, and clustering names with outcomes is
 * how strategy families and sub-regimes emerge.
 *
 * (Phase 1: charter only. Implementation lands in a later milestone.)
 */

/**
 * The **support guard** the future grader/RunRecord (kestrel-a57.1) applies before banking any
 * expected-$ from a fill cell. A cell's E[$] is banked **only** when its `FillSupport` is
 * `"calibrated"`; an `"extrapolated"` cell — or an unstated one — banks **$0** on the gain side: the
 * Allocator refuses to bank paper-$ computed where support == extrapolated, so strategies cannot
 * hill-climb into uncalibrated corners of the fill model.
 *
 * SIGN policy (fail-closed, AGENTS.md "never silently false"): a `"calibrated"` cell banks its E[$]
 * as-is (both signs). An `"extrapolated"` / unstated cell refuses paper PROFIT (→ $0) but does NOT
 * forgive a paper LOSS — zeroing a negative EV would flatter a strategy that routes losing fills into
 * uncalibrated corners (a fail-OPEN, gameable asymmetry, the inverse of the hill-climb this guard
 * prevents). So an extrapolated cell banks only its non-positive part: gains → $0, losses kept.
 *
 * RE-EXPRESSED, NOT FORKED (kestrel-dpy, ADR-0014): the policy and the `FillSupport` vocabulary now
 * live in ONE place — the zero-dependency PROTOCOL home {@link ../protocol/support.ts} (promoted there
 * under kestrel-h314) — and `bankableEv` is that module's function, re-exported here so grade keeps its
 * import surface. Grade imports from the protocol home directly rather than hopping through
 * `../support/index.ts` (itself only a thin re-export of the same protocol surface). The Blotter's signed
 * `fill_claim` and the grader's `bankable` view therefore read the SAME policy and can never disagree. The
 * invariant `bankableEvOf(partition(cells)) === Σ bankableEv(cell.ev, cell.support)` is pinned in
 * `tests/support.partition.test.ts`.
