/**
* cvdiag-emitter.ts — the SHARED TypeScript CVDIAG emitter binding that the
* four TS-backed integrations import (langgraph-typescript, claude-sdk-typescript,
* mastra, built-in-agent). Plan unit: L0-F. Spec: 2026-06-18-flap-observability
* §5 (schema) + §6 (tiers / PII).
*
* ──────────────────────────────────────────────────────────────────────────
* SINGLE SOURCE OF TRUTH — this file RE-EXPORTS, it does NOT redefine.
*
* The canonical CVDIAG schema, edge-header allow/deny filter, PII scrub, and
* the `CvdiagEmitter` (tier resolution, fail-closed DEBUG guard, byte caps,
* bounded queue, UUIDv7 span/test minters) all live in L0-A under
* `showcase/harness/src/cvdiag/`. This binding is a thin barrel that pulls
* those symbols forward so the TS integrations have ONE import surface and so
* a schema change in L0-A propagates here automatically (no duplicate enum to
* drift). Re-exporting (not duplicating) is the whole point of the unit: the
* §5 "single source of truth" / "CI lint fails on drift" policy is only
* enforceable if every emitter shares the L0-A definitions.
*
* The relative path `../../../harness/src/cvdiag/` resolves as:
* showcase/integrations/_shared/ts/ → ../../../harness/src/cvdiag/
* ( _shared/ts → _shared → integrations → showcase )/harness/src/cvdiag
* i.e. from this file up three levels to `showcase/`, then into `harness/`.
* The `.js` extensions match L0-A's ESM (`"type": "module"`, bundler module
* resolution) — at runtime under tsx / a bundler the `.js` specifier resolves
* to the `.ts` source, exactly as the harness's own `index.ts` barrel does.
*
* ──────────────────────────────────────────────────────────────────────────
* CROSS-CONTEXT RESOLUTION FOR L1-E (how a standalone TS integration's Docker
* build sees these files):
*
* Each TS integration (langgraph-typescript, claude-sdk-typescript, mastra)
* already vendors a sibling-directory `shared-tools/` into its build context
* via a `COPY shared-tools/ ./shared-tools/` line in its Dockerfile (the
* build context is the integration dir, so a sibling source tree is copied
* in as a top-level dir, NOT imported across the repo). L1-E MUST use the
* SAME mechanism for CVDIAG:
*
* 1. Stage `_shared/ts/cvdiag-emitter.ts` (this file, with the relative
* re-exports flattened to point at a co-located copy of the L0-A
* sources) AND the three L0-A sources it pulls from
* (`schema.ts`, `edge-headers.ts`, `emit.ts`) into the integration's
* build context — e.g. under `shared-tools/cvdiag/` or a dedicated
* `_cvdiag/` dir — exactly as `shared-tools/` is copied today.
* 2. Add `COPY shared-tools/cvdiag/ ./shared-tools/cvdiag/` (or the chosen
* path) to each integration Dockerfile, mirroring the existing
* `COPY shared-tools/ ./shared-tools/` line.
* 3. The integration's CVDIAG wiring imports
* `from "../../shared-tools/cvdiag/cvdiag-emitter"` (path per chosen
* layout) rather than reaching across the monorepo — standalone npm
* projects have no path alias back to `showcase/harness`.
*
* This is the TS analogue of L0-C's Python `_shared/cvdiag_bootstrap`: a
* COPY-into-context staging step, NOT a workspace/path-alias import. Within
* THIS slot (the harness/worktree) the relative `../../../harness/...`
* re-export resolves directly so the vitest suite runs against the real L0-A
* sources; L1-E performs the COPY-staging flatten when packaging each
* integration. A `bin/showcase cvdiag stage-ts` helper (or the existing
* build wrapper) is the natural home for the copy, so the staging is a
* build step and not hand-maintained per integration.
