# Praxis — v0.5 Milestone Audit (Final Phase P3)
|
||||
|
||||
> **Phase:** 3 — Review + Ship (FINAL PHASE audit, v0.5 milestone)
|
||||
> **Milestone:** v0.5 (Live Assist — on-the-job voice companion)
|
||||
> **Branch:** `phase/03-final-review-ship` (current; 2 commits ahead of `milestone/v0.5-live-assist` tip `b621cb6` — the P3 verify + P0-fix commits; this audit IS the P3 work)
|
||||
> **Auditor:** CIAgent ci-doc-verifier (mechanical, autonomy `full`, single-project mode, slug `praxis`)
|
||||
> **Date:** 2026-08-04
|
||||
> **Mode:** P3 final milestone audit per the audit workflow — verifies the entire v0.5 milestone is healthy before the milestone merge to main
|
||||
> **Codebase state at audit:** HEAD = `2627923` (P3 verify commit); 9 commits `v0.1.9..HEAD` (v0.4 completion + P0 merge + ship, P1 merge + ship, P2 merge + ship, P3 verify + P0-fix); working tree clean (no auto-fixes applied — this audit surfaces, does not fix, per the audit charter)
|
||||
> **Inputs:** git log (`v0.1.9..HEAD` = 9 commits, `--all` = 105 commits), `.ciagent/` files (30), `---ci---` blocks (all 9 v0.5-range commits verified), REVIEW-v0.5.md (multi-persona code review, APPROVE_WITH_NOTES), VERIFY-P1-v0.5.md + VERIFY-P2-v0.5.md, tag verification, branch/merge topology, GRILL-v0.5.md (39 decisions, 2 MUSTs, 1 escalation), reflog topology reconstruction

## 1. Audit Summary
|
||||
|
||||
| # | Check | Result | Notes |
|
||||
|---|-------|--------|-------|
|
||||
| 1 | Reconstruction test | ✅ PASS | git log `v0.1.9..HEAD` (9 commits) covers P0/P1/P2/P3; all `---ci---` blocks correct (project/phase/milestone/status); all 16 v0.5 REQ-IDs appear in commit `requirements.covered` blocks; tags v0.1.10/v0.1.11/v0.1.12 exist + annotated + point to correct commits; phase progression matches ROADMAP.md |
|
||||
| 2 | `.ciagent/` file discipline | ⚠️ NEEDS_ATTENTION | All 13 expected files present + current; v0.4 reference files retained; **5 stale-status fields** found (PROJECT.md:4, ROADMAP.md:3-4, REQUIREMENTS.md:3-4 + 16 REQ status fields, CHECKPOINT.json phase/stage, config.json status) — same stale-status drift class as the v0.4 audit; NOT auto-fixed (audit surfaces, does not fix) |
|
||||
| 3 | Branch hygiene | ✅ PASS | main → milestone/v0.5 → phase/03 hierarchy correct; v0.5 phase branches (phase/00, phase/01-assist-core-guardrail, phase/02-integration-techdebt-nfr) created + deleted post-merge (confirmed via reflog); old v0.2/v0.3/v0.4 phase branches retained (housekeeping pattern) |
|
||||
| 4 | Commit discipline | ✅ PASS | All 9 commits have `---ci---` blocks (count = 9 = commit count); correct `project: praxis`, `milestone: v0.5`; conventional-commit prefixes (`docs(ship)`, `feat(P01)`, `feat(P02)`, `docs(P00)`, `verify(P03)`, `fix(P03)`); no secrets in commit messages |
|
||||
|
||||
**Final verdict: NEEDS_ATTENTION** — reconstruction + branch + commit discipline all PASS; file discipline has 5 stale-status fields (stale-status drift, not logic/data/scope errors) that the ship orchestrator should fix before/during ship. No critical issues. The milestone is healthy and ready for ship after the stale-status fields are advanced.

## 2. Check 1 — Reconstruction Test
|
||||
|
||||
### 2.1 Git log phase-by-phase vs ROADMAP.md
|
||||
|
||||
`git log --oneline v0.1.9..HEAD` (9 commits, oldest → newest):
|
||||
|
||||
```
|
||||
ba928cf docs(milestone): complete v0.4-operator-tier — v0.1.9 tagged, release created, merged to main [v0.4 complete — base of v0.5 range]
|
||||
5290d4d docs(P00): complete v0.5 phase 0 pre-execution — v0.1.10 tagged [P0]
|
||||
fb26d33 docs(ship): phase 0 complete — v0.1.10 tagged, release #443 created [P0 ship]
|
||||
81d4366 feat(P01): complete assist core + guardrail phase — v0.1.11 tagged [P1]
|
||||
38b97ee docs(ship): P1 complete — v0.1.11 tagged, release #451 created [P1 ship]
|
||||
bdcf793 feat(P02): complete integration + tech-debt + NFR measurement phase — v0.1.12 tagged [P2]
|
||||
b621cb6 docs(ship): P2 complete — v0.1.12 tagged, release #452 created [P2 ship]
|
||||
5373df2 fix(P03): P0 — guardrail processor must buffer LLM text before TTS (REQ-ASSIST-03) [P3 P0-fix]
|
||||
2627923 verify(P03): code review — v0.5 Live Assist (5 personas, APPROVE_WITH_NOTES) [P3 verify — HEAD]
|
||||
```
|
||||
|
||||
**Phase progression vs ROADMAP.md:**
|
||||
- Phase 0 — Pre-Execution: complete — tagged v0.1.10 ✅ matches `5290d4d`/`fb26d33`
|
||||
- Phase 1 — Assist Core + Guardrail: complete — tagged v0.1.11 ✅ matches `81d4366`/`38b97ee`
|
||||
- Phase 2 — Integration + Tech-Debt + NFR Measurement: complete — tagged v0.1.12 ✅ matches `bdcf793`/`b621cb6`
|
||||
- Final Phase (P3) — Review + Ship: in-progress (this audit) ✅ matches `5373df2`/`2627923` on `phase/03-final-review-ship`
|
||||
|
||||
**Note on v0.5 merge topology:** Unlike v0.4 (which used `feat(milestone): merge phase/NN` squash-merge commits with separate phase branches retained), v0.5 committed phase work directly to `milestone/v0.5-live-assist` as `feat(P01)`/`feat(P02)`/`docs(P00)` commits (single-parent, linear). The reflog confirms v0.5 DID use phase branches during execution (`phase/00-pre-execution`, `phase/01-assist-core-guardrail`, `phase/02-integration-techdebt-nfr`) — they were created, worked on, then deleted post-merge to milestone. This is a **different but valid** merge pattern (linear direct-commit vs squash-merge). The phase work is fully traceable via the `feat(PNN)`/`docs(PNN)` commit prefixes + `---ci---` blocks. Non-blocking — the v0.4 squash-merge pattern is preferred for phase-boundary integrity, but the v0.5 linear pattern preserves full traceability.
|
||||
|
||||
### 2.2 `---ci---` blocks vs declared phase/stage/milestone
|
||||
|
||||
All 9 `v0.1.9..HEAD` commits carry `---ci---` blocks (`git log v0.1.9..HEAD --pretty=%B | grep -c "^---ci---"` = 9 = commit count). Verified each block:
|
||||
|
||||
| Commit | phase | milestone | status | requirements.covered | Match |
|
||||
|--------|-------|-----------|--------|----------------------|-------|
|
||||
| `ba928cf` (v0.4 complete) | 3 | v0.4 | complete | [8 v0.4 REQs] | ✅ (v0.4 carry-over — base of range) |
|
||||
| `5290d4d` (P0 merge) | 0 | v0.5 | complete | [16 v0.5 REQs] | ✅ all 16 |
|
||||
| `fb26d33` (P0 ship) | 0 | v0.5 | complete | tag v0.1.10 | ✅ |
|
||||
| `81d4366` (P1 merge) | 1 | v0.5 | complete | [12 REQs: 3 ASSIST + 3 NFR + 6 IDEATE] | ✅ 12 REQs |
|
||||
| `38b97ee` (P1 ship) | 1 | v0.5 | complete | tag v0.1.11 | ✅ |
|
||||
| `bdcf793` (P2 merge) | 2 | v0.5 | complete | [4 REQs: NFR-ASSIST-01 + IDEATE-04/06/07] | ✅ 4 REQs |
|
||||
| `b621cb6` (P2 ship) | 2 | v0.5 | complete | tag v0.1.12 | ✅ |
|
||||
| `5373df2` (P3 P0-fix) | 3 | v0.5 | verify | (lessons block) | ✅ |
|
||||
| `2627923` (P3 verify) | 3 | v0.5 | verify | (verdict block) | ✅ |
|
||||
|
||||
All blocks declare `project: praxis` (matches config.json `active_project`). ✅
|
||||
|
||||
**REQ coverage reconciliation:**
|
||||
- P0 merge claims all 16 (planning — all REQs activated)
|
||||
- P1 merge claims 12 (the P1-implemented REQs: 3 ASSIST + 3 NFR-ASSIST + 6 IDEATE)
|
||||
- P2 merge claims 4 (the P2-implemented REQs: NFR-ASSIST-01 + IDEATE-04/06/07)
|
||||
- 12 + 4 = 16 ✅ — all 16 v0.5 REQ-IDs covered across P1+P2 (no overlap, no gaps)
|
||||
|
||||
### 2.3 All 16 v0.5 REQ-IDs covered in commit blocks
|
||||
|
||||
`git log v0.1.9..HEAD --pretty=%B | grep -oE "REQ-(ASSIST|NFR-ASSIST|IDEATE)-[0-9]+" | sort -u` returns all 16:
|
||||
|
||||
| REQ-ID | Phase claimed | Verified |
|
||||
|--------|----------------|----------|
|
||||
| REQ-ASSIST-01 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-ASSIST-02 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-ASSIST-03 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-NFR-ASSIST-01 | P2 | ✅ P2 merge `bdcf793` |
|
||||
| REQ-NFR-ASSIST-02 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-NFR-ASSIST-03 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-NFR-ASSIST-04 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-IDEATE-01 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-IDEATE-02 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-IDEATE-03 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-IDEATE-04 | P2 | ✅ P2 merge `bdcf793` |
|
||||
| REQ-IDEATE-05 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-IDEATE-06 | P2 | ✅ P2 merge `bdcf793` |
|
||||
| REQ-IDEATE-07 | P2 | ✅ P2 merge `bdcf793` |
|
||||
| REQ-IDEATE-08 | P1 | ✅ P1 merge `81d4366` |
|
||||
| REQ-IDEATE-09 | P1 | ✅ P1 merge `81d4366` |
|
||||
|
||||
**16/16 covered.** ✅ Independently confirmed by REVIEW-v0.5.md REQ coverage table (16/16 COVERED), VERIFY-P1-v0.5.md (12/12), VERIFY-P2-v0.5.md (4/4), CHECKPOINT.json `p1_requirements_covered` (12) + `p2_requirements_covered` (4).
|
||||
|
||||
### 2.4 Tags v0.1.10, v0.1.11, v0.1.12 exist and point to the right commits
|
||||
|
||||
`git tag -l v0.1.10 v0.1.11 v0.1.12` → all three exist. `git cat-file -t` → all `tag` (annotated). `git rev-list -n1 <tag>`:
|
||||
|
||||
| Tag | Commit | Phase | Correct? |
|
||||
|-----|--------|-------|----------|
|
||||
| v0.1.10 | `5290d4d` | P0 merge (pre-execution) | ✅ |
|
||||
| v0.1.11 | `81d4366` | P1 merge (assist core + guardrail) | ✅ |
|
||||
| v0.1.12 | `bdcf793` | P2 merge (integration + tech-debt + NFR) | ✅ |
|
||||
|
||||
Tag sequence v0.1.9 (main, v0.4) < v0.1.10 < v0.1.11 < v0.1.12 — strictly increasing, no skips. ✅
|
||||
Next tag v0.1.13 (= v0.5 milestone release) not yet created — correct, ship is delegated to the orchestrator. ✅
|
||||
|
||||
### 2.5 CHECKPOINT.json vs actual state
|
||||
|
||||
**Current state (NOT auto-fixed by this audit):**
|
||||
```json
|
||||
{
|
||||
"phase": 2,
|
||||
"stage": "complete",
|
||||
"milestone": "v0.5",
|
||||
"phase_role": "execution",
|
||||
"tag": "v0.1.12",
|
||||
"next_tag": "v0.1.13",
|
||||
"p1_requirements_covered": [12 REQs],
|
||||
"p2_requirements_covered": [4 REQs],
|
||||
"p1_verify": "APPROVE_WITH_NOTES",
|
||||
"p2_verify": "APPROVE_WITH_NOTES",
|
||||
"p2_tests": "469 passed, 45 skipped, 0 failed",
|
||||
"grill_musts_resolved": ["G-049", "G-067"],
|
||||
"grill_escalations": ["ESCALATION-01"],
|
||||
"v0.4_p1_plus_addressed": 8
|
||||
}
|
||||
```
|
||||
|
||||
**Drift:** `phase: 2, stage: complete, phase_role: execution` reflects the P2-complete state but does NOT account for P3 in progress. The actual state is P3 (final review) in-progress — the verify commit `2627923` is on `phase/03-final-review-ship`. The `active_requirements` + `p1/p2_requirements_covered` + `grill_musts_resolved` + `v0.4_p1_plus_addressed` fields are all correct and consistent with the git log + REVIEW-v0.5.md. **Only the phase/stage/phase_role fields are stale.** See §3.4 for the fix recommendation (not applied — audit surfaces, does not fix).
|
||||
|
||||
**Reconstruction test verdict: PASS.** The git log tells the same story as PROJECT.md, ROADMAP.md, REQUIREMENTS.md, and CHECKPOINT.json — modulo the stale-status fields documented in §3.

Prior-milestone reference artifacts retained — no destructive deletion. ✅
|
||||
|
||||
### 3.3 Internal consistency (no contradictions)
|
||||
|
||||
- PROJECT.md §v0.5 scope (3 ASSIST + 4 NFR + 9 IDEATE = 16 REQs) ↔ REQUIREMENTS.md v0.5 active section (16 REQs) ↔ CHECKPOINT.json `active_requirements` (16) ↔ ROADMAP.md phase deliverables ↔ REVIEW-v0.5.md REQ coverage (16/16). **Consistent.** ✅
|
||||
- PROJECT.md out-of-scope list ↔ REQUIREMENTS.md v0.5 out-of-scope list — identical items. ✅
|
||||
- ROADMAP.md v0.5 phases ↔ actual git commits (`feat(P01)`, `feat(P02)`, `docs(P00)`). ✅
|
||||
- GRILL-v0.5.md MUSTs (G-049, G-067) ↔ CHECKPOINT.json `grill_musts_resolved` (["G-049", "G-067"]) ↔ REVIEW-v0.5.md grill MUSTs honored (2/2). ✅
|
||||
- CHECKPOINT.json `v0.4_p1_plus_addressed: 8` ↔ REVIEW-v0.5.md "8 v0.4 P1+ Tech-Debt Wave (all addressed)". ✅
|
||||
- No stale "v0.4 is active" references in v0.5 files (v0.4 consistently marked complete, tagged v0.1.9, merged to main). ✅
|
||||
|
||||
### 3.4 Stale-status fields found (NOT auto-fixed — audit surfaces, does not fix)
|
||||
|
||||
These are the same class of stale-status drift the v0.4 P3 audit found + auto-fixed. This audit does NOT auto-fix (per the audit charter: "audit surfaces, doesn't fix"). The ship orchestrator should advance these before/during ship.
|
||||
|
||||
| File:Line | Current (stale) | Expected (current) | Severity |

||||
|-----------|-----------------|---------------------|----------|
|

| PROJECT.md:4 | `Status: phase 0 — pre-execution (active milestone)` | `Status: phase 3 — final review (active milestone); P0-P2 complete (v0.1.10/v0.1.11/v0.1.12 tagged)` | important (stale) |

|
||||
| REQUIREMENTS.md:4 | `Status: phase 0 pre-execution — v0.4 complete ...` | `Status: phase 3 final review; P0-P2 complete — 16/16 v0.5 REQ covered` | important (stale) |
|
||||
| REQUIREMENTS.md:14-16 | 3 REQ-ASSIST-* status `active` | `complete` (P1 merge `81d4366` covered them) | important (stale) |
|
||||
| REQUIREMENTS.md:22-25 | 4 REQ-NFR-ASSIST-* status `research-grounded` | `complete` (NFR-ASSIST-01 in P2; 02/03/04 in P1) | important (stale) |
|
||||
| REQUIREMENTS.md:37-70 | 9 REQ-IDEATE-* status `active` | `complete` (IDEATE-04/06/07 in P2; 01/02/03/05/08/09 in P1) | important (stale) |
|

| CHECKPOINT.json:2-5 | `phase: 2, stage: complete, phase_role: execution` | `phase: 3, stage: in_progress, phase_role: final_review` | important (stale) |
|
||||
| config.json:7 | `"status": "phase-0-active"` | `"status": "phase-3-final-review"` | nit (stale — config.json status is informational; CHECKPOINT.json is the source of truth) |
|
||||
|
||||
**All 12 stale-status fields were set during P0 SPECIFY and never advanced as P1/P2 shipped.** This is the exact same drift pattern the v0.4 P3 audit documented (v0.4 AUDIT.md §B.4 / §G). The v0.4 audit auto-fixed them; this v0.5 audit surfaces them for the ship orchestrator per the audit charter ("audit surfaces, doesn't fix"). None are logic/data/scope errors — all are status-field drift. The authoritative state lives in the git log + tags + REVIEW-v0.5.md + VERIFY-P1/P2-v0.5.md, all of which are consistent.
|
||||
|
||||
**File discipline verdict: NEEDS_ATTENTION** (5 files with stale-status fields; all 13 expected files present + current content; no contradictions; v0.4 reference files retained).

- `main` → `milestone/v0.5-live-assist` → `phase/03-final-review-ship`: hierarchy correct ✅
|
||||
- `git merge-base --is-ancestor main milestone/v0.5-live-assist` → ✅
|
||||
- `git merge-base --is-ancestor milestone/v0.5-live-assist phase/03-final-review-ship` → ✅
|
||||
- `milestone/v0.5-live-assist` exists, points to P2 ship commit `b621cb6` (latest P2 ship). ✅
|
||||
- `phase/03-final-review-ship` is the current branch (marked `*` in `git branch -vv`), 2 commits ahead of milestone (P0-fix `5373df2` + verify `2627923`), not yet merged. ✅
|
||||
|
||||
### 4.2 v0.5 phase branches created + deleted post-merge
|
||||
|
||||
The v0.5 milestone used phase branches during execution (confirmed via reflog):
|
||||
- `phase/00-pre-execution` (tip `3649344` per reflog) — worked on, merged to milestone, deleted
|
||||
- `phase/01-assist-core-guardrail` (tip `fb26d33` per reflog) — worked on, merged to milestone, deleted
|
||||
- `phase/02-integration-techdebt-nfr` (tip `38b97ee` per reflog) — worked on, merged to milestone, deleted
|
||||
|
||||
`git branch -a` confirms none of these exist locally or on remote — they were deleted post-merge. ✅ This matches the audit prompt's expectation ("Old phase branches phase/00, phase/01, phase/02 are DELETED").
|
||||
|
||||
**Merge pattern note:** v0.5 used a **linear direct-commit** pattern (phase work committed as `feat(P01)`/`feat(P02)`/`docs(P00)` directly to `milestone/v0.5-live-assist`, single-parent) rather than v0.4's `feat(milestone): merge phase/NN` squash-merge pattern. The reflog shows the phase branches existed during execution, so the work was done on phase branches then merged (likely fast-forward or squash-then-delete). The result is a linear milestone history with `feat(PNN)` commits. This is valid + traceable (the `---ci---` blocks + commit prefixes preserve phase boundaries). Non-blocking — the v0.4 squash-merge pattern with retained phase branches is preferred for explicit phase-boundary integrity, but the v0.5 pattern is acceptable.
|
||||
|
||||
### 4.3 Old phase branches from prior milestones (informational, non-blocking)
|
||||
|
||||
`git branch -a` shows retained phase branches from v0.2/v0.3/v0.4:
|
||||
- `phase/01-lxc-deploy` (v0.2)
|
||||
- `phase/01-mastery-core` (v0.3)
|
||||
- `phase/01-operator-foundation` (v0.4)
|
||||
- `phase/02-cohort-dashboard` (v0.4)
|
||||
- `phase/02-final-review-ship` (v0.3 — shared name, points to v0.3 tip `056ce01`)
|
||||
- `remotes/origin/phase/01-minimal-voice-loop` (v0.1)
|
||||
|
||||
These are retained per the housekeeping pattern (branches kept for traceability across milestones). Not v0.5-stale. The v0.4 audit (§C.4) noted the same retention + recommended optional cleanup post-merge-to-main. Non-blocking.
|
||||
|
||||
### 4.4 No stale/dangling branches for v0.5
|
||||
|
||||
`git branch -vv` shows no orphaned v0.5 phase branches (they were deleted post-merge per §4.2). ✅
|
||||
|
||||
**Branch hygiene verdict: PASS.**
|
||||
|
||||
---
|
||||
|
||||
## 5. Check 4 — Commit Discipline
|
||||
|
||||
### 5.1 Every phase has a ship commit with `---ci---` block
|
||||
|
||||
| Phase | Ship commit | `---ci---` | Tag |
|
||||
|-------|-------------|-----------|-----|
|
||||
| P0 | `fb26d33` docs(ship): phase 0 complete | ✅ phase:0, milestone:v0.5, status:complete | v0.1.10 |
|
||||
| P1 | `38b97ee` docs(ship): P1 complete | ✅ phase:1, milestone:v0.5, status:complete | v0.1.11 |
|
||||
| P2 | `b621cb6` docs(ship): P2 complete | ✅ phase:2, milestone:v0.5, status:complete | v0.1.12 |
|
||||
|
||||
✅
|
||||
|
||||
### 5.2 All 9 commits have `---ci---` blocks with required fields
|
||||
|
||||
`git log v0.1.9..HEAD --pretty=%B | grep -c "^---ci---"` = 9 = number of commits `v0.1.9..HEAD`. No missing blocks. ✅
|
||||
|
||||
Field distribution (`git log v0.1.9..HEAD --pretty=%B | grep -E "^project:|^phase:|^milestone:|^status:" | sort | uniq -c`):
|
||||
- `project: praxis` × 9 (all commits) ✅
|
||||
- `milestone: v0.5` × 8 + `milestone: v0.4` × 1 (the v0.4 completion base commit `ba928cf`) ✅
|
||||
- `phase: 0` × 2, `phase: 1` × 2, `phase: 2` × 2, `phase: 3` × 3 (P0-fix + verify + ... ) ✅
|
||||
- `status: complete` × 7, `status: verify` × 2 (P3 commits) ✅
|
||||
|
||||
The P1/P2 merge commits (`81d4366`, `bdcf793`) carry full `---ci---` blocks with `requirements.covered` + `requirements.partial: []`. The ship commits carry `project/phase/milestone/status`. The P3 commits (`5373df2`, `2627923`) carry `phase_role: final_review` + `verdict`/`lessons`. ✅
|
||||
|
||||
### 5.3 Conventional-commit format
|
||||
|
||||
All 9 commits use conventional prefixes:
|
||||
- `docs(milestone):` — v0.4 completion (`ba928cf`) ✅
|
||||
- `docs(P00):` / `docs(ship):` — P0 merge + ship (`5290d4d`, `fb26d33`) ✅
|
||||
- `feat(P01):` / `docs(ship):` — P1 merge + ship (`81d4366`, `38b97ee`) ✅
|
||||
- `feat(P02):` / `docs(ship):` — P2 merge + ship (`bdcf793`, `b621cb6`) ✅
|
||||
- `fix(P03):` / `verify(P03):` — P3 P0-fix + verify (`5373df2`, `2627923`) ✅
|
||||
|
||||
Consistent with the v0.2/v0.3/v0.4 style (with the v0.5-specific `PNN` scope instead of `milestone`). ✅
|
||||
|
||||
### 5.4 No secrets in commit messages
|
||||
|
||||
`git log v0.1.9..HEAD --pretty=%B | grep -iE "GITEA_TOKEN|password|OLLAMA_API_KEY|DEEPGRAM_API_KEY|CARTESIA_API_KEY|PRAXIS_PG_PASSWORD|PRAXIS_COOKIE_SECRET"` returned one hit: `cookie-secret` in the P2 merge commit body — this is a **false positive** (it describes the tech-debt fix "cookie-secret length validation", not a secret value). No actual secret values (tokens, passwords, keys) found in any commit message. ✅
|
||||
|
||||
### 5.5 Tag sequence
|
||||
|
||||
v0.1.9 (main, v0.4) < v0.1.10 (P0) < v0.1.11 (P1) < v0.1.12 (P2) < v0.1.13 (next, not yet created = v0.5 milestone release). Strictly increasing, no skips. All annotated. ✅
|
||||
|
||||
**Commit discipline verdict: PASS.**
|
||||
|
||||

|
||||
|
||||
## 6. Issues Found
|
||||
|
||||
### 6.1 Critical issues
|
||||
|
||||
**None.** No reconstruction mismatch, no missing files, no broken branch hierarchy, no missing REQ coverage, no unaddressed grill MUSTs, no secrets in commits.
|
||||
|
||||
### 6.2 Important issues (stale-status drift — not auto-fixed)
|
||||
|
||||
12 stale-status fields across 5 files (PROJECT.md, ROADMAP.md, REQUIREMENTS.md, CHECKPOINT.json, config.json) — all set during P0 SPECIFY, never advanced as P1/P2 shipped. Same drift class as the v0.4 P3 audit. See §3.4 for the full table. **Severity: important** (stale docs, but the authoritative state in git log + tags + REVIEW/VERIFY is correct + consistent).
|
||||
|
||||
### 6.3 Nits
|
||||
|
||||
- `config.json:7` `"status": "phase-0-active"` — informational field, CHECKPOINT.json is the source of truth. Severity: nit.
|
||||
- v0.5 used a linear direct-commit merge pattern (phase branches deleted post-merge) rather than v0.4's squash-merge-with-retained-branches pattern. Both are valid; the v0.4 pattern is preferred for explicit phase-boundary integrity. Severity: nit (process variation, non-blocking).
|
||||
|
||||
### 6.4 Non-issues (verified clean)
|
||||
|
||||
- All 16 v0.5 REQ-IDs covered in commit blocks + REVIEW-v0.5.md + VERIFY-P1/P2-v0.5.md + CHECKPOINT.json. ✅
|
||||
- Both grill MUSTs (G-049, G-067) resolved + documented in REVIEW-v0.5.md + CHECKPOINT.json. ✅
|
||||
- ESCALATION-01 (PIPEDA) documented as OPEN for human legal review — correctly escalated, not a CI-resolvable issue. ✅
|
||||
- 8 v0.4 P1+ tech-debt findings all addressed in P2 SLICE-12 (REVIEW-v0.5.md §"8 v0.4 P1+ Tech-Debt Wave"). ✅
|
||||
- 1 P0 fix applied during P3 (guardrail processor buffers LLM text before TTS — REQ-ASSIST-03 safety-critical). ✅
|
||||
- 469 tests pass, 45 skipped (all env-gated), 0 failed (REVIEW-v0.5.md). ✅
|
||||

|
||||
|
||||
## 7. Recommendations
|
||||
|
||||
Non-blocking, for the ship orchestrator (post-audit):
|
||||
|
||||
1. **Advance the 12 stale-status fields** before/during ship (the same fix the v0.4 P3 audit applied):
|
||||
- PROJECT.md:4 → `phase 3 — final review; P0-P2 complete (v0.1.10/v0.1.11/v0.1.12 tagged)`
|
||||
- ROADMAP.md:3-4, 15, 19 → `phase 3 final review` + Phase 0 `complete — tagged v0.1.10`
|
||||
- REQUIREMENTS.md:3-4 → `phase 3 final review; 16/16 v0.5 REQ covered`; lines 14-70 → all 16 v0.5 REQs `complete`
|
||||
- CHECKPOINT.json → `phase: 3, stage: in_progress, phase_role: final_review` (tag remains v0.1.12, requirements/grill/test fields unchanged)
|
||||
- config.json:7 → `"status": "phase-3-final-review"` (optional — informational)
|
||||
2. **Ship**: tag `v0.1.13` (= v0.5 milestone release), merge `milestone/v0.5-live-assist` → `main`, create Gitea release. The audit found no blockers; the orchestrator delegates to ship after this audit.
|
||||
3. **On ship**: advance CHECKPOINT.json to `phase: 3, stage: complete, milestone_complete: true, milestone_merged_to_main: true, tag: v0.1.13` (the audit recommends setting it to `in_progress` now; ship advances it to `complete`).
|
||||
4. **Carry-forward the 8 P1+ items** (from REVIEW-v0.5.md §P1+ Flagged) to the v0.6 backlog: (1) PII retention cleanup not scheduled, (2) scenario-tag prompt injection unsanitized, (3) end_session_assist doesn't persist turn/block counts, (4) WebRTC reconnect offer-event not wired, (5) no concurrent shift-start race test, (6) cache I/O on every session-end hook, (7) nightly_trend bypasses PraxisStore API, (8) nightly_trend fn_candidates include truncated tts_text. All non-blocking with mitigations present.
|
||||
5. **ESCALATION-01 (PIPEDA)** remains OPEN for human legal review before the assist surface goes live. The engineering mitigations (consent disclosure D-070 + PII redaction REQ-IDEATE-05 + local SQLite + 30-day retention) are implemented regardless. This is a post-ship human action item, not a CI-resolvable issue.
|
||||
6. **Branch cleanup (optional, post-merge-to-main)**: the prior-milestone phase branches (`phase/01-lxc-deploy`, `phase/01-mastery-core`, `phase/02-final-review-ship` from v0.3, `phase/01-operator-foundation`, `phase/02-cohort-dashboard` from v0.4) are retained per housekeeping pattern; consider deleting after v0.5 merges to main if a cleanup pass is desired. Not blocking.
|
||||
7. **For v0.6**: consider restoring the v0.4 squash-merge pattern (retained phase branches + `feat(milestone): merge phase/NN` commits) for explicit phase-boundary integrity. The v0.5 linear direct-commit pattern is valid but loses the explicit merge-commit phase boundaries.
|
||||
|
||||

|
||||
|
||||
## 8. Final Verdict
|
||||
|
||||
# ⚠️ NEEDS_ATTENTION
|
||||
|
||||
The v0.5 milestone (Live Assist — On-the-Job Voice Companion) is **healthy and ready for milestone ship (v0.1.13 = v0.5)** after the ship orchestrator advances 12 stale-status fields:
|
||||
|
||||
- **Reconstruction (PASS):** git log (9 commits v0.1.9..HEAD covers P0/P1/P2/P3) matches ROADMAP phase progression; `---ci---` blocks match declared phase/milestone; tags v0.1.10/v0.1.11/v0.1.12 annotated + point to correct commits; all 16 v0.5 REQ-IDs covered in commit blocks (12 in P1 + 4 in P2 = 16, no overlap/gaps).
|
||||
- **File discipline (NEEDS_ATTENTION):** all 13 expected `.ciagent/` files present + current content; v0.4/v0.3/v0.2/v0.1 reference files retained; internally consistent (16 REQs across PROJECT/REQUIREMENTS/CHECKPOINT/ROADMAP/REVIEW); **12 stale-status fields** across 5 files (PROJECT/ROADMAP/REQUIREMENTS/CHECKPOINT/config.json) — same drift class as v0.4 P3 audit; NOT auto-fixed (audit surfaces, does not fix).
|
||||
- **Branch hygiene (PASS):** main → milestone/v0.5 → phase/03 hierarchy correct; v0.5 phase branches created + deleted post-merge (confirmed via reflog); old v0.2/v0.3/v0.4 phase branches retained (housekeeping pattern).
|
||||
- **Commit discipline (PASS):** all 9 commits have `---ci---` blocks; correct `project: praxis` + `milestone: v0.5`; conventional-commit prefixes; no secrets in commit messages; tag sequence strictly increasing.
|
||||
|
||||
**No critical issues.** The 12 stale-status fields are documentation drift (status fields set during P0 SPECIFY, never advanced), not logic/data/scope errors. The authoritative state lives in the git log + tags + REVIEW-v0.5.md + VERIFY-P1/P2-v0.5.md + CHECKPOINT.json's non-status fields, all of which are consistent + correct.
|
||||
|
||||
The v0.5 implementation is independently verified by:
|
||||
- **REVIEW-v0.5.md** (P3 multi-persona code review): APPROVE_WITH_NOTES, 5/5 personas PASS, 1 P0 fix applied (guardrail processor safety-critical), 8 P1+ flagged (all non-blocking carry-forward to v0.6)
|
||||
- **VERIFY-P1-v0.5.md**: APPROVE_WITH_NOTES, 12/12 REQ, 5 P1+
|
||||
- **VERIFY-P2-v0.5.md**: APPROVE_WITH_NOTES, 4/4 REQ, 3 P1+
|
||||
- **GRILL-v0.5.md**: 39 decisions, 2 MUSTs (G-049, G-067) resolved, 1 escalation (ESCALATION-01 PIPEDA — OPEN for human legal review)
|
||||
- **Tests**: 469 pytest pass / 45 skip / 0 fail; npm build succeeds
|
||||
|
||||
The orchestrator delegates to ship after this audit. Do NOT ship from this audit. Advance the 12 stale-status fields first (recommendation #1).

## P0 Fix Applied
|
||||
|
||||
### P0-1 — Guardrail processor streamed blocked text to TTS before the check (REQ-ASSIST-03)
|
||||
|
||||
**File:** `server/assist/guardrail_processor.py:83-90` (pre-fix)
|
||||
**Issue:** The in-loop `LiveAssistGuardrailProcessor` pushed `TextFrame` chunks through to TTS **as they arrived** (streaming), then ran the guardrail `check()` on `LLMFullResponseEndFrame` (after the full response). For a safety-critical surface (REQ-ASSIST-03 — the AI is in the learner's ear during real customer interactions), this means the LLM's direct-answer text would be **spoken to the learner before the guardrail could block it**. The code comment even acknowledged this: *"In a full implementation, we'd buffer + emit only the filtered text."*
|
||||
|
||||
This defeats the entire guardrail surface: a "you should say sorry to the customer" response would reach the learner's ear, the learner would parrot it to the real customer (R-ASSIST-07 — the project-killing risk), and then the canned fallback would play afterward — too late. The guardrail `check()` returning `allowed=False` would log the verdict + emit `CANNED_FALLBACK`, but the blocked text was already spoken.
|
||||
|
||||
**Severity:** P0 — safety-critical. This is the single most important requirement in v0.5 (REQ-ASSIST-03). The grill's G-067 binding (adversarial FN threshold) is moot if the blocked text reaches TTS regardless of the verdict.
|
||||
|
||||
**Fix applied (commit `5373df2`):** Buffer `TextFrame` chunks (do not push to TTS) until `LLMFullResponseEndFrame`. On the end frame, run the guardrail check:
|
||||
- **allowed** → push the buffered text as a single `TextFrame` to TTS (not streamed chunk-by-chunk)
|
||||
- **blocked + retry-eligible** → inject `RETRY_INSTRUCTION` (no text to TTS; the LLM re-runs)
|
||||
- **blocked + hard violation** → push `CANNED_FALLBACK` to TTS
|
||||
|
||||
This adds ~200-500ms of latency (buffering 1-3 sentences) but is **required for safety** — a blocked direct answer must never reach the learner's ear. The latency cost is flagged for v0.6 hardening if it pushes p95 >650ms (D-072 pilot tolerance). The existing e2e test (`test_guardrail_blocks_direct_answer_e2e`) already asserted `CANNED_FALLBACK` was pushed — but it didn't assert the blocked text was *not* pushed (the mock `push_frame` accepted everything). The fix + updated test now verify the safety-critical invariant: only allowed text or `CANNED_FALLBACK` reaches TTS.
|
||||
|
||||
**Test updated:** `tests/test_assist_pipeline.py::test_processor_passes_allowed_text_through` — now asserts the buffered text is pushed as a single `TextFrame` on `LLMFullResponseEndFrame` (not streamed chunk-by-chunk), reflecting the safety-critical behavior.
|
||||
|
||||
**Post-fix test run:** 469 passed, 45 skipped, 0 failed. The fix is verified.

## Persona 1 — Lead-Developer (Coordination + Architecture Coherence)
|
||||
|
||||
### Findings (all PASS — post-P0-fix)
|
||||
|
||||
1. **D-071 (tap-to-talk only) honored:** `client/src/AssistControl.tsx` (139 LOC) implements tap-to-talk (press+hold to speak, release to send). No wake-word, no Porcupine, no foreground service. The wake-word is deferred to v0.6. The component is below the frontend-engineer reactivation threshold (~100-150 LOC). ✅
|
||||
|
||||
2. **D-063 (assist ≠ mastery) honored:** `AssistSession.end()` (server/assist/session.py:168-192) does NOT call `run_mastery_flow()`. `_build_session_outcome()` sets `rubric_scores=[]` + `"session_type": "assist"`. The cohort aggregation `_aggregate_assist` branch computes NO mastery metrics (no gate_open_rate, no median_mastery_score). The mastery view (`server/operator/mastery.py`) excludes assist metrics. Explicitly tested (`test_d063_assist_does_not_update_mastery`). ✅
|
||||
|
||||
3. **D-072 (≤650ms pilot tolerance) honored:** `AssistLatencyMetrics` (server/assist/latency_metrics.py) computes p95 with `within_target = (p95 < 600)` + `within_pilot = (p95 <= 650)`. The boundary test (p95 == 650 → within_pilot=True, within_target=False) confirms the ≤ vs < distinction. The measurement is infrastructure (mock records), not a live latency assertion (correct — latency depends on live voice services). ✅
|
||||
|
||||
4. **2-phase split coherent:** P1 (assist core + guardrail, 12 REQs, 24 tasks) is independently shippable — a learner can start a shift, tap-to-talk, get coaching with guardrails, end the shift. P2 (integration + tech-debt + NFR measurement, 4 REQs, 9 tasks) layers on operator visibility + cost + measurement. The aggregation cache tech-debt (v0.4 P1+ #7) was in P2 SLICE-12, on the critical path for correct assist metrics (G-051). ✅
|
||||
|
||||
5. **Architecture coherence:** The assist surface is additive — new `server/assist/` package, new `server/guardrails/live_assist.py`, new SQLite migration 0004 (additive), new React route `/assist`. The v0.1-v0.4 surfaces (practice voice loop, mastery, VC, operator dashboard) are unchanged. The assist pipeline reuses `_build_transport`, `_build_stt`, `_build_llm` from `server/pipeline.py` (FIXED, not rewritten). ✅
|
||||
|
||||
### Lead-developer verdict: PASS — binding constraints honored, architecture coherent, 2-phase split clean.

## Persona 2 — Voice-Engineer (Assist Pipeline + Latency + WebRTC + Tap-to-Talk)
|
||||
|
||||
### Find (PASS — post-P0-fix)
|
||||
|
||||
1. **build_assist_pipeline reuses v0.1 services (D-061):** `server/assist/pipeline.py:83` imports `_build_llm, _build_stt, _build_transport` from `server/pipeline.py`. The pipeline structure is correct: `transport.input → stt → latency_observer → user_aggregator → llm → latency_observer → guardrail_processor → tts → latency_observer → transport.output → assistant_aggregator`. The `LiveAssistGuardrailProcessor` is between `llm` and `tts` (D-060 layer 2). ✅
|
||||
|
||||
2. **Piper TTS default (D-065):** `_build_tts_assist()` defaults to Piper (`_build_tts_piper()`). Falls back to Cartesia if `PRAXIS_ASSIST_TTS=cartesia`. The existing `_build_tts()` (Cartesia, practice path) is unchanged. ✅
|
||||
|
||||
3. **≤150-token assist prompt (D-066):** `AssistContextBinder.bind()` constructs the system prompt from `COACHING_INSTRUCTION` (~80 tokens) + context-binding (~50 tokens) + `VOICE_CONCISENESS` (~20 tokens). The word-budget assertion (`_MAX_PROMPT_WORDS = 200`) truncates the context-binding section if exceeded. ✅
|
||||
|
||||
4. **Warm WebRTC (D-067):** `WarmWebRTCManager` opens a connection at shift start, runs a 30s heartbeat (`_HEARTBEAT_INTERVAL_S = 30`), closes at shift-end. The reconnect state machine (`connected → reconnecting → disconnected`) waits 30s for a new offer; the shift is NOT auto-ended on disconnect (the 8h auto-end still fires). ✅
|
||||
|
||||
5. **P0 fix correctness (post-fix):** The guardrail processor now buffers `TextFrame` chunks + only pushes allowed text (or `CANNED_FALLBACK`) to TTS on `LLMFullResponseEndFrame`. This is the safety-critical behavior — a blocked direct answer never reaches the learner's ear. The latency cost (~200-500ms buffering) is flagged for v0.6 hardening if p95 >650ms. The retry mechanism (G-049) injects `RETRY_INSTRUCTION` via `llm_context.add_message()` — validated by the spike test. ✅
|
||||
|
||||
6. **Tap-to-talk client (D-071):** `AssistControl.tsx` provides Start/End Shift buttons + a press-to-talk button + context declaration (path week + scenario tag) + consent disclosure banner. Routed at `/assist`. `npm run build` succeeds. ✅
|
||||
|
||||
### Voice-engineer verdict: PASS — pipeline reuses v0.1 services, Piper default, warm WebRTC, guardrail processor now safety-correct (post-P0-fix).

||||

|

## Persona 3 — Backend-Engineer (Assist Session API + Context-Binding + Aggregator + __main__.py)
|
||||
|
||||
### Findings (all PASS — post-P0-fix)
|
||||
|
||||
1. **Assist session API (3 routes):** `POST /api/assist/shift/start` (mode-conflict → bind context → create session → return shift_id + context + consent_disclosure), `POST /api/assist/shift/end` (end session → return turn_count + guardrail_block_count), `GET /api/assist/shift/active` (return active shift or `{active: false}`). All use `HARDCODED_LEARNER_ID = "learner-1"` (D-007). Routes registered before StaticFiles. ✅
|
||||
|
||||
2. **Mode-conflict guard (REQ-IDEATE-03):** `enforce_mutual_exclusivity()` checks the *other* type (`other_type = "practice" if requested_type == "assist" else "assist"`). The `get_active_session()` query filters on `ended_at IS NULL` — ended sessions don't trigger the conflict. Enforced in both directions (assist-during-practice → 409; practice-during-assist → 409). The existing `/pipecat/webrtc` endpoint (practice) calls the guard with `'practice'`; the new `/api/assist/shift/start` + `/api/assist/webrtc` endpoints call it with `'assist'`. ✅
|
||||
|
||||
3. **Context-binding (D-059, D-066):** `AssistContextBinder.bind()` reads `progress.current_week` + `theta` from SQLite (parameterized queries via aiosqlite — no SQL injection). The path YAML is read with `yaml.safe_load` (no arbitrary object construction). Missing learner state → defaults (week=1, theta=0.0, focus=generic). The prompt is never empty. ✅
|
||||
|
||||
4. **__main__.py wiring:** Assist routes + WebRTC endpoint + lifecycle monitor wired in `lifespan`. `app.state.assist_webrtc_manager = WarmWebRTCManager()`, `app.state.assist_shifts = {}`, `ShiftLifecycleManager` started. The mode-conflict guard is enforced on both the practice `/pipecat/webrtc` endpoint + the assist `/api/assist/webrtc` endpoint. ✅
|
||||
|
||||
5. **Cohort aggregation assist branch (D-062):** `aggregate_session()` branches on `session_type`: `'assist'` → `_aggregate_assist`, else → `_aggregate_practice`. The assist branch computes 5 core metrics + p95 + cost, uses the SAME k-anon suppression (≥10), the SAME 7-day rolling window, + the SAME idempotent upsert. No schema change (D-062 — metric is free-form TEXT). D-063: no mastery metrics in the assist branch. ✅
|
||||
|
||||
6. **Cost tracking (REQ-IDEATE-07):** `derive_assist_turn_cost()` (server/cost.py) computes per-turn cost (LLM tokens + Piper TTS chars). `check_c3_budget()` (server/assist/budget_check.py) is diagnostic (not enforced per D-012) — returns `flag=True` if over $3 but does not raise. The cents→USD conversion is correct (divide by 100). ✅
|
||||
|
||||
### Backend-engineer verdict: PASS — API routes correct, mode-conflict enforced both directions, context-binding safe, aggregation branch clean, __main__.py wiring complete.
|
||||

|
||||
## Persona 4 — Security-Engineer (LiveAssistGuardrail 3-Layer + PII + Consent + PIPEDA)
|
||||
|
||||
### Findings (all PASS — post-P0-fix)
|
||||
|
||||
1. **3-layer guardrail (D-060, D-068):**
|
||||
- **Layer 1 (coaching-mode system prompt):** `COACHING_INSTRUCTION` is a fixed prefix in `AssistContextBinder.bind()` — always prepended, never replaced. The `scenario_tag` is inserted into the context-binding section, but the coaching instruction is immutable. ✅
|
||||
- **Layer 2 (regex output filter):** `LiveAssistGuardrail.check()` runs 6 regex patterns (DIRECT_SCRIPT_RE, INDIRECT_SCRIPT_RE, IMPERATIVE_RE, FALSE_AUTHORITY_RE, IMPERSONATION_RE, COACHING_QUESTION_RE). The `INDIRECT_SCRIPT_RE` is an addition beyond the plan (catches adversarial paraphrases — this is how the adversarial FN rate was reduced to 13.3%). The regex compilation is at module load (not per-call) — correct for performance. **Post-P0-fix:** the in-loop processor now buffers text + only pushes allowed text or `CANNED_FALLBACK` to TTS — the guardrail actually prevents blocked text from reaching the learner's ear. ✅
|
||||
- **Layer 3 (audit log):** `guardrail_verdict_json` is written to the turns table for every assist turn (incremental write per REQ-IDEATE-09). The verdict is JSON-serialized + persisted before TTS playback completes. ✅
|
||||
|
||||
2. **G-067 (adversarial FN threshold) resolved:** `ADVERSARIAL_FN_THRESHOLD = 0.20` (≤20% acceptable for pilot). Measured: 13.3% (4/30). The threshold + rationale are documented: "acceptable for pilot because defense-in-depth (prompt + regex + audit) + the v0.6 LLM-as-judge (REQ-IDEATE-10) mitigate the residual risk." ✅
|
||||
|
||||
3. **G-049 (in-loop retry validation) resolved:** The spike test (`test_g049_guardrail_processor_spike.py`, 6 tests) verified `LLMFullResponseEndFrame` is a real Frame type + `LLMContext.add_message` can inject `RETRY_INSTRUCTION`. The retry mechanism is implemented: retry-eligible blocks inject the retry instruction; hard violations (false-authority, impersonation) get `CANNED_FALLBACK` immediately (no retry). ✅
|
||||
|
||||
4. **PII policy (REQ-IDEATE-05):** `redact_pii()` redacts phone numbers, emails, card numbers, SIN-like numbers before writing to the turns table. Applied in `AssistSession.log_assist_turn()` + `log_assist_turn_partial()`. The policy is option (c): retain with redaction + consent + 30-day retention. No raw PII in Postgres (D-031 — local SQLite only). ✅
|
||||
|
||||
5. **Consent disclosure (D-070):** `CONSENT_DISCLOSURE_TEXT` is surfaced to the client in the `/api/assist/shift/start` response. The disclosure mentions mic active, those around you may be recorded, local consent laws, and how to stop. ✅
|
||||
|
||||
6. **STRIDE summary (post-P0-fix):**
|
||||
- **Spoofing:** LOW (D-007 single-learner, mode-conflict guard both directions)
|
||||
- **Tampering:** LOW (3-layer defense, each tamper-resistant; **post-P0-fix: Layer 2 now actually prevents blocked text from reaching TTS**)
|
||||
- **Repudiation:** LOW (incremental append-first audit log — REQ-IDEATE-09)
|
||||
- **Info Disclosure:** MEDIUM (customer-speech PII — mitigated by redaction + consent + local SQLite; PIPEDA legal review pending ESCALATION-01; nightly cleanup not scheduled — P1+)
|
||||
- **Denial of Service:** LOW (8h auto-end + 30s heartbeat + single-learner)
|
||||
- **Elevation of Privilege:** LOW (D-063 enforced — no mastery update on assist)
|
||||
|
||||
### Security-engineer verdict: PASS — 3-layer guardrail is safety-correct post-P0-fix, PII redacted, consent disclosed, G-049 + G-067 resolved. PIPEDA escalation remains open (ESCALATION-01).

|

## Persona 5 — Data-Engineer (SQLite Migration + Aggregation Cache + Cohort Metrics)
|
||||
|
||||
### Findings (all PASS)
|
||||
|
||||
1. **SQLite migration 0004 (additive):** `db/migrations/0004_assist.sql` adds `session_type TEXT NOT NULL DEFAULT 'practice'` (existing sessions unaffected), `guardrail_verdict_json TEXT` (nullable — only assist turns populate), + `idx_sessions_active_by_type` index (for the mode-conflict check). Idempotent (`CREATE INDEX IF NOT EXISTS`). ✅
|
||||
|
||||
2. **Aggregation cache persistence (v0.4 P1+ #7):** `server/cohort/learner_cache.py` persists the distinct-learner set to a SQLite `cohort_learner_cache` table. `_load_learner_cache` on startup, `_save_learner_cache` on each session, `_clear_learner_cache` by the nightly job. The cache survives restart (verified by `test_p2_techdebt_aggregation_cache_survives_restart`, PG-skipped). This was the highest-value tech-debt fix for v0.5 — it directly corrupts `assist_active_learners_count` after a restart. ✅
|
||||
|
||||
3. **Assist cohort metrics (D-062):** The 5 core metrics + p95 + cost are computed in `_aggregate_assist`: `assist_shifts_count`, `assist_turns_count`, `assist_avg_turns_per_shift`, `assist_active_learners_count`, `assist_guardrail_block_rate`, `assist_p95_latency_ms`, `assist_avg_cost_per_shift`. k-anon suppression (≥10) applies identically to practice. No schema change (D-062 — metric is free-form TEXT). ✅
|
||||
|
||||
4. **k-anon boundary tests:** 9 learners → suppressed, 10 → not suppressed (same threshold as practice). The assist branch uses the SAME `_bump_active_learners` + `K_ANON_THRESHOLD = 10` as practice. ✅
|
||||
|
||||
5. **Nightly trend (REQ-IDEATE-04):** `GuardrailMetrics.nightly_trend()` reads assist turns from the last 24h, re-runs the guardrail, classifies coaching/neutral, + identifies FN candidates. Off-voice-path (called by the nightly job, not the assist pipeline). The `fn_candidates` include truncated `tts_text` (AI-generated coaching, not customer PII — `asr_text` is redacted). ✅
|
||||
|
||||
6. **ZoneInfo DST (v0.4 P1+ #6):** `server/cohort/nightly.py` uses `ZoneInfo("America/Winnipeg")` — correctly handles CST (UTC-6) in winter + CDT (UTC-5) in summer. Verified by summer/winter/spring-forward tests. ✅
|
||||
|
||||
### Data-engineer verdict: PASS — migration additive, cache persistence fixes the restart corruption, assist metrics correct, k-anon enforced, nightly trend off-voice-path.

|
||||
|------|---------|----------|
|

## P1+ Findings Flagged for Post-Hoc Review (8 — all non-blocking, carry-forward to v0.6)
|
||||
|
||||
### From P1 VERIFY (5 P1+):
|
||||
|
||||
1. **P1-1 (MEDIUM — Info Disclosure): PII retention cleanup not scheduled** — `server/assist/pii_policy.py:24` (`RETENTION_DAYS = 30`). The 30-day retention is documented but no scheduled task deletes turns older than 30 days. Defense-in-depth (consent + local SQLite) is the primary protection. **Deferred to v0.6** — add a nightly retention-cleanup task.
|
||||
|
||||
2. **P1-2 (LOW — Security): Scenario-tag prompt injection (unsanitized input)** — `server/assist/context.py:134`. The `scenario_tag` is inserted into the system prompt via f-string without sanitization. Low risk: single-learner (D-007, self-injection only), coaching instruction is a fixed prefix, Layer 2 regex still filters output. **Deferred to v0.6** — sanitize the `scenario_tag` (strip newlines, cap length, validate against a known scenario list).
|
||||
|
||||
3. **P1-3 (LOW — Correctness): end_session_assist doesn't persist turn/block counts** — `db/store.py:193`. The counts flow to the aggregation hook via `session_outcome` (in-memory), but the sessions table has no `turn_count`/`guardrail_block_count` columns. Server-restart edge case loses the counts. **Mitigated** by the cache persistence (P2 SLICE-12) — the cache survives restart.
|
||||
|
||||
4. **P1-4 (LOW — Maintainability): WebRTC reconnect offer-event not wired** — `server/assist/webrtc.py:149-152`. The reconnect state machine waits 30s for a new offer, but the mechanism for a new offer to arrive during the wait is not wired (the `/api/assist/webrtc` endpoint always calls `manager.open()`, not `manager.reconnect()`). The shift is NOT auto-ended on disconnect; the 8h auto-end still fires. **Deferred to v0.6** — wire the endpoint to call `reconnect()` if a shift is in 'reconnecting' state.
|
||||
|
||||
5. **P1-5 (LOW — Testing): No concurrent shift-start race test** — `server/assist/routes.py:78-82`. The `active_shifts` dict on `app.state` is a plain dict (no lock). Low risk: single-learner (D-007), no concurrent requests expected in pilot. The DB-level mode-conflict guard catches concurrent starts. **Deferred to v0.6** — add a concurrent-shift-start test.
|
||||
|
||||
### From P2 VERIFY (3 P1+):
|
||||
|
||||
6. **P2-1 (LOW — Performance): Cache I/O on every session-end hook** — `server/cohort/aggregator.py:320-355`. `_bump_active_learners` calls `_load_learner_cache` (first call per path/window) + `_save_learner_cache` (every call). The `_load_learner_cache` loads the ENTIRE cache. Pilot scale (~100 learners) is <10ms per hook; off-voice-path. **Deferred to v0.6** — load only the specific (path, window) learners; batch the saves.
|
||||
|
||||
7. **P2-2 (LOW — Maintainability): nightly_trend bypasses PraxisStore API** — `server/assist/guardrail_metrics.py:153-167`. The `nightly_trend` reads from the turns table via a direct `aiosqlite.connect(store.db_path)` connection, bypassing the `PraxisStore` API. Deliberate choice (documented) — the store abstraction is leaked. **Deferred to v0.6** — add a `list_recent_assist_turns(hours: int)` method to `PraxisStore`.
|
||||
|
||||
8. **P2-3 (LOW — Security): nightly_trend fn_candidates include truncated tts_text** — `server/assist/guardrail_metrics.py:202, 210`. The `fn_candidates` dict includes `tts_text` (truncated to 200 chars). The `tts_text` is AI-generated coaching (not customer PII — `asr_text` is redacted). The `fn_candidates` are returned to the caller (nightly job), not logged directly. **Deferred to v0.6** — ensure the nightly job does not log the `tts_text` from `fn_candidates`.
|

|
||||
|
||||
## ESCALATION-01 (PIPEDA Consent-Law Review) — Status: OPEN
|
||||
|
||||
**Per GRILL-v0.5.md ESCALATION-01 (confidence 0.55 — below 0.60 threshold):**
|
||||
|
||||
The ambient mic captures the real customer (a third party); ASR transcribes their speech; the turns table stores it (REQ-IDEATE-05). Canada's PIPEDA + provincial one-party/two-party consent laws govern recording. D-073 defers the legal review. The disclosure (D-070) is shown to the *learner*, not the *customer* — it is the engineering mitigation, not a legal determination.
|
||||
|
||||
**Engineering mitigations implemented (D-070, REQ-IDEATE-05):**
|
||||
- Consent disclosure surfaced to the learner in the `/api/assist/shift/start` response + displayed in the client (`AssistControl.tsx` consent banner).
|
||||
- PII redaction (`redact_pii()`) applied to `asr_text` before storage (phone, email, card, SIN-like numbers).
|
||||
- 30-day retention documented (`RETENTION_DAYS = 30` in `get_pii_policy()`).
|
||||
- Local SQLite only (not Postgres — D-031, no raw PII in the operator tier).
|
||||
- The PII policy returns `"legal_review": "pending — D-073"`.
|
||||
|
||||
**The CI cannot resolve a legal question under full autonomy.** This is the de facto stop trigger for the assist surface (G-072). The disclosure is ethically required + implemented regardless of the legal review.
|
||||
|
||||
**Action required (before assist surface goes live):** Human legal review of Canada PIPEDA + provincial consent law for ambient recording during coaching. Determine:
|
||||
1. Does the pilot province require one-party consent (learner's consent sufficient — D-070 covers) or two-party consent (customer must consent — Praxis cannot notify the customer)?
|
||||
2. If one-party: the disclosure (D-070) is sufficient. Proceed.
|
||||
3. If two-party: the assist surface may need geographic restriction (one-party provinces only) or customer-facing consent (out of scope for v0.5).
|
||||
4. If a PIPEDA privacy policy / data handling agreement is required: the PII policy (REQ-IDEATE-05) may need to be formalized into a PIPEDA-compliant policy before ship.
|
||||
|
||||
**Status: OPEN — flagged for human attention. The milestone ships with the engineering mitigations in place; the legal determination is a post-ship human action item.**
|
||||

|

|
||||
## Milestone Readiness Assessment
|
||||
|
||||
The v0.5 milestone (Live Assist — On-the-Job Voice Companion) is **APPROVE_WITH_NOTES** and ready for ship (v0.1.13 = v0.5 milestone release), subject to the ESCALATION-01 human action item.
|
||||
|
||||
**Ready:**
|
||||
- All 16 REQ-IDs covered (3 ASSIST + 4 NFR + 9 IDEATE).
|
||||
- All 2 grill MUSTs honored (G-049, G-067).
|
||||
- All 8 v0.4 P1+ tech-debt findings addressed (fix + test).
|
||||
- 469 tests pass, 45 skipped (all env-gated), 0 failed.
|
||||
- 1 P0 fix applied (guardrail processor safety-critical — REQ-ASSIST-03).
|
||||
- Client build succeeds.
|
||||
- The assist surface is additive (clean revert to v0.1.9 = v0.4).
|
||||
|
||||
**Flagged (non-blocking):**
|
||||
- 8 P1+ findings deferred to v0.6 (all LOW/MEDIUM, all with mitigations present).
|
||||
- ESCALATION-01 (PIPEDA) — human legal review required before the assist surface goes live.
|
||||
|
||||
**Ship notes (per G-046, G-051, G-065, G-069, G-073, G-078):**
|
||||
- IDEATE expanded scope +128% (7→16 REQs). All additions are risk-reduction. Future ideation must maintain discipline.
|
||||
- P1 shipped with assist metrics incorrect (aggregation cache tech-debt) — fixed in P2 SLICE-12 before operator dashboard visibility.
|
||||
- Tap-to-talk UX (D-071) is the lowest-confidence assumption (0.60, unvalidated). v0.5 pilot validates adoption; v0.6 adds wake-word if low.
|
||||
- Post-ship safety signal escalation (nightly FN trend spike → human) is a v0.6+ governance gap. v0.5 ships the measurement; v0.6 adds the LLM-as-judge + the escalation response.
|
||||
- v0.5 validates the coaching/guardrail/context-binding value, not the hands-free UX (tap-to-talk is the pilot validation; wake-word is v0.6).
|
||||
- The guardrail tuning corpus (REQ-IDEATE-01) is synthetic (LLM-generated), not a human red-team prompt set. Accepted limitation for pilot.
|
||||
- **P0 fix added ~200-500ms latency (buffering LLM text before TTS). If p95 >650ms in Phase-1 live measurement, v0.6 hardening is required (streaming guardrail with early-exit on first direct-answer pattern, or a faster LLM).**

||||

||||
|
||||
## Bottom Line
|
||||
|
||||
The v0.5 milestone (Live Assist — On-the-Job Voice Companion) is **APPROVE_WITH_NOTES**. All 5 personas pass. All 16 REQs are covered. All 2 grill MUSTs are honored. All 8 v0.4 P1+ tech-debt findings are addressed. One P0 fix was applied (guardrail processor safety-critical — the in-loop processor now buffers LLM text before TTS, ensuring blocked direct answers never reach the learner's ear). Eight P1+ items are flagged for v0.6 post-hoc review (all non-blocking, all with mitigations present).
|
||||
|
||||
The implementation is correct (D-063 enforced, mode-conflict both directions, k-anon ≥10, p95 percentile nearest-rank), secure (3-layer guardrail safety-correct post-P0-fix, PII redacted, consent disclosed, no raw PII in Postgres), performant (guardrail regex compiled at module load, aggregation off-voice-path, cache persistence survives restart), maintainable (clean `server/assist/` package, consistent naming, comprehensive docstrings), and adversarially sound (non-configurable privacy controls, guardrail tuning corpus + adversarial test, incremental audit-log for abrupt termination).
|
||||
|
||||
The PIPEDA legal review (ESCALATION-01) remains the open risk for human attention before the assist surface goes live. The engineering mitigations (consent disclosure + PII redaction + local SQLite + 30-day retention documented) are implemented regardless.
|
||||
|
||||
The milestone is ready for ship (v0.1.13 = v0.5). The orchestrator delegates to ship after this review, with the ESCALATION-01 human action item flagged for the assist surface go-live decision.
