/**
 * Synthesis cost telemetry types — canonical TS-first shapes for
 * Phase 6 DIAG-06 cost and parse-failure observability.
 *
 * These interfaces are authored independently of their Zod adapter schema
 * (Plan 06-02) per D0045: the Zod schema declares
 * `satisfies z.ZodType<SynthesisCostTelemetry>` against this independent
 * type so drift is a build error, not a runtime bug.
 *
 * The 14 attribute paths on `SynthesisCostTelemetry` + `SynthesisPerCardTelemetry`
 * land on the `ailf.report` Sanity doc under `summary.synthesis.diagnosis.*`
 * (D6-09). No new sibling doc type (D0033 / D6-09).
 *
 * @see docs/decisions/D0045-type-architecture-and-contract-enforcement.md
 * @see .planning/phases/06-post-run-integration-cost-telemetry/06-CONTEXT.md §D6-09
 * @see .planning/phases/06-post-run-integration-cost-telemetry/06-CONTEXT.md §D6-12
