# Roadmap: v1.94 L4 Analytical Cross-Check Surface

## Result

`v1.94` closed successfully.

## Phases

- [x] **Phase 168: Analytical Check Rows And Review Contract Expansion**
- [x] **Phase 168.1: Analytical Runtime Surface And Proof Lane**

## Target Outcome

- analytical validation records explicit bounded check rows instead of only a
  flatter aggregate review artifact
- each analytical check keeps the source anchors, assumption or regime context,
  and per-check status needed for human judgment
- runtime-facing read paths expose the same analytical cross-check surface
- one bounded analytical proof lane closes the milestone

## Completion Summary

`v1.94` closed by first upgrading the existing `analytical_review` contract
into row-first bounded analytical checks with durable source or regime context,
then carrying that same analytical cross-check surface across
`status`/`runtime_protocol`/bundle-facing runtime paths and closing with a
dedicated analytical proof lane.

### Phase 168: Analytical Check Rows And Review Contract Expansion

**Goal:** Expand the analytical review contract so bounded analytical checks are
first-class rows with explicit context instead of only a flatter aggregate
review payload.
**Depends on:** `v1.93`
**Plans:** 1 plan

Plans:

- [x] `168-01` Add explicit analytical check rows and richer review contract
  context

### Phase 168.1: Analytical Runtime Surface And Proof Lane

**Goal:** Surface the richer analytical cross-check contract on runtime/read
paths and leave one bounded analytical proof lane.
**Depends on:** Phase `168`
**Plans:** 1 plan

Plans:

- [x] `168.1-01` Surface analytical cross-check rows across runtime read paths
  and prove one bounded analytical lane

## Milestone Summary

**Key accomplishments:**

- analytical validation now records row-first bounded check entries including
  `source_cross_reference`
- each analytical check row now keeps exact source anchors, assumption or
  regime context, and reading-depth posture
- runtime-facing read paths now expose a structured
  `analytical_cross_check_surface` through the existing validation review
  bundle
- the milestone closes with one dedicated analytical cross-check proof lane
  while the older analytical judgment lane remains compatible

**Issues deferred:**

- symbolic or CAS-backed analytical execution
- automatic route mutation from analytical outcomes
- multi-candidate analytical comparison beyond one bounded candidate at a time

_For current project status after milestone closure, start the next milestone
with `$gsd-new-milestone`._
