/**
 * Per-critic fidelity windows for the raw `roast` tool's context sizing (N5).
 *
 * The critics are AGENTIC — they read the target repo themselves — so the raw
 * tool's obligation for a large *supplementary* `context` is only to keep each
 * critic from OVERFLOWING its window, not to make every critic see all of it.
 * So we size the context to EACH critic's own window (claude keeps ~1M with the
 * [1m] suffix / ~200k without, codex ≤272k, agy ≤135k) rather than clamping
 * everyone to the smallest — the same per-participant philosophy the GitHub
 * Action's fidelity streams use, applied at the raw layer.
 *
 * NOTE: the window numbers MIRROR packages/github-action/src/inputs.ts
 * (criticFidelityWindow). Keep the two in sync until they are consolidated into
 * a single shared module (deferred: consolidating would re-open the reviewed
 * v1.18.9 action resolver and add an action→root workspace dep + re-bundle).
