# Phase 169.1 Summary

Status: implemented in working tree

## Goal

Wire the runtime proof packet schema surface into the promotion pipeline so
promotion requests, auto-promotion checks, and downstream bridge logic all see
the same explicit runtime schema context instead of relying on hidden
assumptions.

## What Landed

- added `runtime_schema_promotion_bridge.py` as the dedicated runtime proof
  packet bridge helper
- the bridge now:
  - loads package-local proof packet schemas
  - validates discovered runtime artifacts against those schemas
  - translates supported runtime artifacts onto a canonical L2 surface preview
- `request_promotion()` now records runtime schema types, schema paths, and
  artifact paths in the gate payload when proof packets exist
- `auto_promote_candidate()` now blocks auto-promotion if discovered runtime
  proof artifacts fail schema validation
- focused service tests now cover both the positive gate surface and the
  negative invalid-artifact path

## Verification

- bridge module regression slice:
  - `2 passed`
- promotion gate / auto-promotion regression slice:
  - `4 passed`
- schema and Layer 2 regression slice:
  - `18 passed`

## Outcome

`REQ-PROMO-03` through `REQ-PROMO-06` are now satisfied:

- promotion context can discover runtime proof packet schema surfaces
- auto-promotion now treats invalid runtime proof packets as a real blocker
- promotion gates expose runtime schema provenance instead of hiding it
- one dedicated bridge module now owns runtime proof packet validation and
  canonical-surface translation

## Next Step

Proceed to Phase `169.2` for the bounded HCI foundation work.
