# v1.91 Milestone Audit

Status: passed

## Scope Closed

- Phase `165`: Real Topic L0 To L2 End-To-End Validation
- Phase `165.1`: Proof Engineering Knowledge Layer — Schema + Bootstrap
- Phase `165.2`: Mode Envelope Runtime Enforcement + Literature Intake Fast Path
- Phase `165.3`: HCI Foundation — Human-Readable Surfaces + Onboarding
- Phase `165.4`: Agent Governance — Mechanical Verification + Schema Isolation
- Phase `165.5`: L0/L1 Integration — DeepXiv Progressive Reading + Graphify Concept Graph
- Phase `165.6`: Milestone Closure Gap — Public Front Door Real-Topic Proof

## Requirements Coverage

Score: `4/4` requirements satisfied

- `REQ-E2E-01` satisfied
  - one real topic now enters through the public AITP front door with a fresh
    topic slug on the actual repository kernel root
  - evidence:
    - `.planning/phases/165.6/165.6-E2E-CLOSURE-RUNBOOK.md`
    - `.planning/phases/165.6/evidence/jones-von-neumann-algebras-public-entry/COMMANDS.md`
    - `.planning/phases/165.6/evidence/jones-von-neumann-algebras-public-entry/POSTMORTEM.md`

- `REQ-E2E-02` satisfied
  - the milestone now has durable postmortem coverage for both:
    - the earlier Jones routed follow-up run
    - the fresh public-front-door closure run
  - evidence:
    - `.planning/phases/165-real-topic-l0-to-l2-e2e-validation/evidence/jones-von-neumann-algebras/POSTMORTEM.md`
    - `.planning/phases/165.6/evidence/jones-von-neumann-algebras-public-entry/POSTMORTEM.md`

- `REQ-E2E-03` satisfied
  - discovered issues are durably captured in explicit ledgers instead of being
    left in runtime artifacts or chat memory
  - evidence:
    - `.planning/phases/165-real-topic-l0-to-l2-e2e-validation/165-ISSUE-LEDGER.md`
    - `.planning/phases/165.6/165.6-ISSUE-LEDGER.md`

- `REQ-E2E-04` satisfied
  - the issue ledgers route findings into explicit GSD work:
    - shipped follow-up closure through `165.1` to `165.5`
    - new non-blocking debt routed to backlog item `999.86`
  - evidence:
    - `.planning/phases/165.1/165.1-01-SUMMARY.md`
    - `.planning/phases/165.2/165.2-02-SUMMARY.md`
    - `.planning/phases/165.3/165.3-SUMMARY.md`
    - `.planning/phases/165.4/165.4-06-SUMMARY.md`
    - `.planning/phases/165.5/165.5-SUMMARY.md`
    - `.planning/BACKLOG.md`

## Cross-Phase Integration Check

- `165 -> 165.1` passed
  - the initial Jones postmortem exposed proof-engineering memory debt, and the
    shipped `proof_fragment` bootstrap now turns that debt into durable protocol
    state

- `165 -> 165.2` passed
  - the milestone exposed the need for a bounded literature fast path, and
    `165.2` shipped mode-aware staging for that route

- `165 -> 165.3` passed
  - the milestone exposed front-door/HCI friction, and `165.3` shipped readable
    status/next/help/hello/steering surfaces

- `165 -> 165.4` passed
  - the milestone exposed governance/trust visibility debt, and `165.4` shipped
    schema isolation, context injection, theory metrics, loop detection, and
    manifest drift checks

- `165 -> 165.5` passed
  - the milestone exposed shallow `L0 -> L1` reading limits, and `165.5` shipped
    DeepXiv enrichment, concept graphs, progressive reading, graph staging, and
    Obsidian export

- `165 -> 165.6` passed
  - the milestone's final blocker was explicitly the missing public-front-door
    proof, and `165.6` closes that blocker with a fresh slugged real-topic run

## Verification Evidence

- `python -m pytest research/knowledge-hub/tests/test_proof_engineering_bootstrap.py -q`
  - result: `3 passed`
- `python research/knowledge-hub/runtime/scripts/run_first_run_topic_acceptance.py --json`
  - result: `success`
- `python -m pytest research/knowledge-hub/tests -q`
  - result: `579 passed, 22 subtests passed`

## Accepted Open Gaps

- `999.86`: the post-bootstrap `L0 source expansion` action should point more
  directly at concrete shipped source-acquisition entry surfaces
- `999.52`: broader proof-engineering memory distillation beyond the first Jones
  seed remains a later extension, not a blocker for `v1.91`
