# Phase 138 Summary

Status: implemented on `main`

## Goal

Lock one explicit compiled-knowledge contract that extends the current `L2`
compiler helpers with added/updated/provisional/contradiction semantics while
preserving the existing `L4` promotion boundary.

## What Landed

- a new production CLI/service surface:
  `compile-l2-knowledge-report`
- a new compiled artifact family in `l2_compiler.py`:
  - `workspace_knowledge_report.json`
  - `workspace_knowledge_report.md`
- the new compiled-knowledge report now:
  - mixes canonical and staging sources explicitly
  - labels authority level per row
  - distinguishes `trusted`, `provisional`, and `contradiction_watch`
  - emits a bounded `change_summary` against the previous compiled snapshot
  - links back to existing memory-map, graph-report, navigation, and staging
    manifest surfaces
- the `L2_COMPILER_PROTOCOL.md` contract now names the second bounded compiler
  target explicitly

## Outcome

Phase `138` is complete.
`v1.68` now has a first production compiled-knowledge contract instead of only
raw graph/index helper surfaces.
