STATE OF PLAY — Lakehouse

Last verified: 2026-05-03 evening CDT Verified by: live probe (gateway restarted 2x, all 11 catalogd subject tests + 11 biometric tests + 6 audit tests + 4 mcp-server Gate-4 tests green; cross-runtime parity 6/6 byte-identical against live audit logs; live curl roundtrip on /biometric returned 200 + chained audit row), not memory.

Read this FIRST. When the user says "we're working on lakehouse," they mean the working code captured below — NOT what git log framed as "the cutover" or what memory snapshots from 2 days ago suggest. If memory contradicts this file, this file wins. Update it when something is verified working — not when a phase finishes.

WHAT LANDED 2026-05-03 (13 commits this wave — local-first audit substrate + Phase 1.6 BIPA gates)

The dominant work today: docs/specs/SUBJECT_MANIFESTS_ON_CATALOGD.md Steps 1-8 SHIPPED end-to-end + 5 of 7 Phase 1.6 BIPA pre-launch gates + 6th cross-runtime parity probe. Wave was structured as eight ship-then-scrum cycles — every wave caught real bugs, every fix wave landed within the same session.

Commit	What	Verified
d259909	catalogd: Step 1 — SubjectManifest type + Registry CRUD	17 catalogd subject tests PASS
d16131b	catalogd: Step 2 — SubjectAuditWriter HMAC-SHA256 chain + per-subject Mutex + canonical-JSON via BTreeMap	tamper-detection + concurrent-append race tests PASS
bce6dfd	catalogd: Step 3 — bin/backfill_subjects (BIPA-defensible defaults: vertical=unknown, consent=pending_backfill_review, retention=4yr)	100 subjects loaded into live catalog
fef1efd	gateway: Step 4 — wire SubjectAuditWriter into /v1/chat tool dispatch + audit_subject_hits_in (inline, not spawn)	tool calls log accessor.kind="gateway_lookup"
cd8c59a	gateway: Step 5 — AuditingWorkerLookup decorator wraps validator's WorkerLookup; spawns audit on every find()	live /v1/validate produces audit rows
e38f357	subjects Steps 1-4 fixes from cross-lineage scrum (concurrency race, schema-evolution HMAC drift, hardcoded "success" classifier)	41 tests green
15cfd76	catalogd + gateway: Step 6 — /audit/subject/{id} legal-tier endpoint with constant-time-eq token check + tampering detection	live curl returns chain_verified=true
2a4b316	subjects 2nd scrum fix wave (token min 16→32, chain_root from full chain via chain_tip(), rebuild collision warn, tightened result-state heuristic)	17 catalogd + 6 gateway tests PASS
8fc6238	catalogd: Step 7 — bin/retention_sweep (BIPA-aware on biometric clock, idempotent across daily runs, no auto-mutation)	8 sweep tests PASS, live verified at --as-of 2031-06-01 flagging 100/100 expired
2413c96	catalogd: Step 8 — bin/parity_subject_audit (Rust side of cross-runtime parity probe)	known-answer + verify modes match Go byte-for-byte
2222227	parity helper hardening (panic-noise → die() helper, abs path stripped from doc) from scrum	parity probe still 6/6
4708717	Phase 1.6 BIPA wave — Gate 4 absence test (4/4 with bypass coverage), §2 attestation script (3/3 evidence checks), Gate 1/2/5 doc scaffolds with ⚖ COUNSEL markers	4/4 mcp-server Bun tests, 3/3 evidence on live data
c7aa607	Phase 1.6 scrum fixes — schema fingerprint hashes name+type+nullable, Gate 4 catches object-literal + class-field bypasses, pyarrow dep gate, item 7 deferral rationale	4/4 + 3/3 still pass
f1fa6e4	Phase 1.6 Gate 3a — crates/catalogd/src/biometric_endpoint.rs: POST /biometric/subject/{id}/photo with consent gate, quarantined storage (mode 0700/0600), audit chain link, BiometricCollection field on SubjectManifest	11 unit tests PASS, live roundtrip 200
3708e6a	Gate 3a scrum fixes — transactional rollback on audit failure (BIPA convergent BLOCK), Content-Type parameter handling, relative data_path, ts+uuid filename, dead code removed	11 tests + cross-runtime parity 6/6

Cross-runtime parity (post-this-wave): 6 probes, 38/38 byte-identical assertions — validator(6/6) + extract_json(12/12) + session_log(4/4) + materializer(2/2) + embed(8/8) + subject_audit(6/6). Run cd /home/profit/golangLAKEHOUSE && for p in scripts/cutover/parity/*.sh; do bash "$p"; done to re-verify.

Three runtime-divergence classes caught + fixed by the parity probe authoring loop (cataloged because they recur):

1. Go omitempty on string fields strips empty values that Rust serde always emits → broken HMAC
2. time.RFC3339Nano truncates trailing-zero nanoseconds where chrono AutoSi keeps 9 digits → broken HMAC
3. Go json.Marshal HTML-escapes <>& where serde keeps literal → broken HMAC on any field with those chars

All three have regression-locked tests; structural impossibility going forward.

Phase 1.6 BIPA pre-launch gates — status table:

Item	Status	Evidence
Gate 1 — public retention schedule	eng-staged, ⚖ counsel pending	docs/policies/consent/biometric_retention_schedule_v1.md
Gate 2 — informed consent template	eng-staged, ⚖ counsel pending	docs/policies/consent/biometric_consent_template_v1.md
Gate 3a — photo-upload endpoint	DONE	11 unit tests + live POST /biometric/subject/{id}/photo
Gate 3b — deepface classification	deferred	needs Python subprocess design (sidecar dropped 2026-05-02)
Gate 4 — name→ethnicity removal	DONE	mcp-server/phase_1_6_gate_4.test.ts 4/4 with bypass coverage
Gate 5 — destruction runbook	eng-staged, ⚖ counsel pending	docs/runbooks/BIPA_DESTRUCTION_RUNBOOK.md
§2 cryptographic attestation	eng-DONE, signature pending	docs/attestations/BIPA_PRE_IDENTITYD_ATTESTATION_2026-05-03.md (SHA-256 evidence hash, 3/3 checks pass on live data)
§3 employee training	deferred	conditional on operator population size

Calendar bottleneck: counsel review of items 1/2/5/6. Engineering long pole is Gate 3b (deepface) — needs design conversation before engineering starts.

Operational state:

• LH_SUBJECT_AUDIT_KEY=/tmp/lakehouse_audit/subject_audit.key (32-byte HMAC signing key) loaded into systemd unit
• LH_LEGAL_AUDIT_TOKEN_FILE=/tmp/lakehouse_audit/legal_audit.token (44-char legal-tier token) loaded into systemd unit
• data/_catalog/subjects/ holds 100 backfilled WORKER-N.json manifests + per-subject WORKER-N.audit.jsonl HMAC chains
• data/biometric/uploads/<safe_id>/<ts>_<uuid>.<ext> quarantined photo storage (mode 0700 dir / 0600 file). 2 photos uploaded for WORKER-2 during live verify.
• /audit/subject/{id} mounted on gateway with chain_verified=true on every probe
• /biometric/subject/{id}/photo mounted on gateway, refuses 403 without consent.biometric.status="given"

VERIFIED WORKING RIGHT NOW

The client demo (Staffing Co-Pilot)

Public URL: https://devop.live/lakehouse/ — 200, "Staffing Co-Pilot" (159 KB SPA, leaflet maps, dark theme). Local URL: http://localhost:3700/ — same page, served by mcp-server/index.ts (PID 1271, started 09:48 CDT today).

The staffers console (the one the client was thoroughly impressed with):

• https://devop.live/lakehouse/console — 200, "Lakehouse — What Your Staffing System Would Do" (26 KB)
• Pulls project index via /api/catalog/datasets (36 datasets) + playbook memory via /api/vectors/playbook_memory/stats (4,701 entries with embeddings, real ops like "fill: Maintenance Tech x2 in Milwaukee, WI")

Client-visible flow that works end-to-end on the public URL:

Endpoint	Sample output
GET /api/catalog/datasets	36 datasets indexed: timesheets 1M, call_log 800K, workers_500k 500K, email_log 500K, workers_100k 100K, candidates 100K, placements 50K, job_orders 15K, successful_playbooks_live 2,077
GET /api/vectors/playbook_memory/stats	4,701 fill operations with embeddings
GET /system/summary	36 datasets, 2.98M rows, 60 indexes, 500K workers loaded, 1K candidates
POST /intelligence/staffing_forecast	744 Production Workers needed in 30d, 11,281 bench (4,687 reliable), coverage 1,444%, risk=ok. Same for Electrician (need 32, bench 2,440) and Maintenance Tech (need 17, bench 5,004).
POST /intelligence/permit_contracts	permit 3442956 $500K → 3 Production Workers, 886-candidate pool, 95% fill, $36K gross. 5 more Chicago permits with 8 workers each, same pool, 95% fill, $96K each.
POST /intelligence/market	major Chicago permits ranked: $730M O'Hare, $615M 307 N Michigan, $580M casino, $445M Loop transit (real geo coords).
POST /intelligence/permit_entities	architects + contractors from permit contacts (e.g. "KACPRZYNSKI, ANDY", "SLS ELECTRICAL SERVICE").
POST /intelligence/activity + /intelligence/arch_signals + /intelligence/chat	all 200

The demo tells the story: "upcoming Chicago contracts → workers needed → coverage from the bench → architects/contractors involved → revenue and margin." That's the "live data + anticipating contracts + complete workflow" pitch — working as of right now.

DO NOT RELITIGATE

• PR #11 is merged into origin/main as ed57eda — do not "still need to merge PR #11."
• Distillation tag distillation-v1.0.0 at e7636f2 is FROZEN — do not re-architect schemas, scorer rules, audit fixtures.
• Kimi forensic HOLD verdict (2026-04-27) was 2/8 false + 6/8 latent — do not re-debate, see reports/kimi/audit-last-week-full.md.
• candidates_safe vertical column bug — fixed at catalog metadata layer in commit c3c9c21. Do not "discover" it again.
• Decisions A/B/C/D from synthetic-data-gap-report.md — all four scripts shipped today (d56f08e, 940737d, c3c9c21). Do not "ask J for approval."
• workers_500k.phone type fixup — already string. The fixup script is idempotent; running it is a no-op.
• client_workerskjkk typo dataset — was breaking every SQL query (catalog had it registered, file didn't exist). Removed via DELETE /catalog/datasets/by-name/client_workerskjkk this session. Do not re-add. Adding a startup gate that errors on unrecognized parquet names is the long-term fix per now.md Step 2C.
• Python sidecar dropped from hot path 2026-05-02 (ba928b1) — AiClient calls Ollama directly. Do not "wire python embedding back in." lab_ui.py + pipeline_lab.py keep running as dev-only UIs (not on the runtime path).
• Lance backend gauntlet (2026-05-02) — sanitizer over all 5 routes, 7 unit tests, 9-probe smoke, 10M re-bench. The doc_id btree auto-builds inside lance_migrate AND lance-bench. Do not "discover" the missing scalar index again or the leaked filesystem paths in error bodies.
• Cross-runtime parity = 32/32 across 5 probes in golangLAKEHOUSE/scripts/cutover/parity/. Do not "build a parity probe for X" without checking — validator, extract_json, session_log, materializer, and embed are all already covered.
• Decisions tracker is golangLAKEHOUSE/docs/ARCHITECTURE_COMPARISON.md — single living source of truth for cross-runtime decisions. As of 2026-05-02 it has 0 _open_ code work items; only 2 strategic items left (Lance vs Parquet+HNSW-with-spilling, Go-vs-Rust primary cutover).
• PRD line 70 is load-bearing — "Everything runs locally, no cloud APIs." Yesterday's PR #13 violated this by routing customer hot-path inference to opencode/openrouter/ollama_cloud. REVERTED 2026-05-03 (d054c0b). The customer hot path (modes.toml staffing_inference, doc_drift_check; execution_loop overseer escalation) is now local Ollama (qwen3.5:latest). Cloud providers stay configured in providers.toml for explicit dev-tool opt-in only (scrum, auditor, bot/propose). Do NOT re-add cloud models to the hot path defaults — the customer demo runs on local + free.
• /v1/usage shows by_provider=ollama only for any customer-shape request. If you see by_provider including kimi/openrouter/opencode/ollama_cloud for normal /v1/iterate or /v1/respond traffic, something has regressed. Verify with: curl -sf http://127.0.0.1:3100/v1/usage | jq .by_provider.
• ./scrum is a TOOL, not architecture. Lives at repo root. J runs it manually. Outputs findings to data/_kb/scrum_findings.jsonl (the KB). Findings inform development; they do NOT auto-fold into PRDs/design docs/code. If you find yourself proposing to "wire scrum into [some pipeline]" — stop. It's J's tool.
• Test code in main is ACTIVELY being cleaned out. 2026-05-03 commits 6aafd41 + f4ebd22 removed 12 orphaned dev experiments (~2900 LOC) from tests/real-world/ and scripts/. If you find more zero-reference experimental files, surface them — don't auto-delete unless the pattern is clearly a one-time-experiment-with-zero-consumers like the ones already removed.

FIXES MADE THIS SESSION (2026-04-27 evening)

1. crates/gateway/src/v1/iterate.rs:93 — state → _state (cleared the one cargo warning).
2. lakehouse-ui.service (Dioxus) — disabled. Was failing 7,242 times against a missing target/dx/ui/debug/web/public build dir. systemctl stop && disable.
3. VCP UI on :3950 — started bun run ui/server.ts (PID 1162212, log /tmp/lakehouse_ui.log). /data/* endpoints now 200 with real data.
4. client_workerskjkk catalog entry — DELETE /catalog/datasets/by-name/client_workerskjkk removed the dead manifest. This was the actual root cause of /system/summary reporting workers_500k_rows: 0 and the demo showing zero bench. Every SQL query was failing schema inference on the missing file before reaching its target table. Fixed → workers_500k_rows: 500000, candidates_rows: 1000, demo coverage flipped from "critical 0%" to actual percentages on devop.live/lakehouse.

FIXES MADE THIS SESSION (2026-04-28 early — face pool)

5. Synthetic StyleGAN face pool — 1000 faces, gender+race+age tagged. scripts/staffing/fetch_face_pool.py fetches from thispersondoesnotexist.com; scripts/staffing/tag_face_pool.py --min-age 22 runs deepface and excludes minors. data/headshots/manifest.jsonl now has gender (494 men / 458 women), race (caucasian 662 · east_asian 128 · hispanic 86 · middle_eastern 59 · black 14 · south_asian 3), age, and 48 minor exclusions. Server pool = 952 servable faces.
6. mcp-server/index.ts:1308 /headshots/:key route — gender×race×age intersection bucketing with graceful fallback (gender-only → all). Same key always returns same face; different keys spread evenly.
7. /headshots/_thumbs/ pre-resized 384×384 webp (60× smaller: 587KB → ~11KB). Without this, 40-card grids overran Chrome's parallel-connection budget and ~75% of tiles never finished decoding. Generated via parallel ffmpeg (xargs -P 8); .gitignored.
8. mcp-server/search.html + console.html — dropped img.loading='lazy'. With 11KB thumbs, eager load is cheap (~500KB for 50 cards) and avoids the off-screen race that lazy decode produced.
9. ComfyUI on-demand uniqueness — serve_imagegen.py:32 added seed to _cache_key() (was caching by prompt only — 3 different worker seeds collapsed to 1 cached image). Verified: seed=839185194/195/196 → 3 distinct md5s.
10. mcp-server/index.ts:1234 /headshots/generate/:key — ComfyUI hot-path that derives a deterministic-per-worker seed via djb2-style hash; cold ~1.5s, cached ~1ms. Worker prompt format: professional corporate headshot portrait of a {age}-year-old {race} {gender}, {role}, neutral expression, plain studio background, soft natural lighting, sharp focus, photorealistic, dslr. Cache at data/headshots_gen/ (gitignored, regeneratable).
11. Confidence-default name resolution in search.html — genderFor() and guessEthnicityFromFirstName() lookup tables (FEMALE_NAMES, MALE_NAMES, NAMES_HISPANIC, NAMES_BLACK, NAMES_SOUTH_ASIAN, NAMES_EAST_ASIAN, NAMES_MIDDLE_EASTERN). Xavier → man+hispanic, Aisha → woman+black, etc. Every worker resolves to a face-pool bucket.

End-to-end verified: playwright run on https://devop.live/lakehouse/?q=forklift+operators+IL → 21/21 cards loaded, 0 broken, all 384×384 webp thumbs.

⚠ PRODUCTION-READY BLOCKER (2026-05-03)

Audit-trail capability is the gate to client signature. Smoke + parity tests prove the surface compiles; they do NOT prove an audit response can be produced for a specific person. Staffing client won't sign without defensible discrimination-claim response capability.

Authoritative document: docs/AUDIT_TRAIL_PRD.md — drafted 2026-05-03. Defines worked example (John Martinez at Warehouse B), the per-decision audit row schema, the surface map of where decisions happen today, current-state-vs-target gap table, and 9-phase implementation sequence.

Phase 1 (discovery walk) requires NO J approval — it's read-only. Phases 2+ have explicit open questions in §10 of the PRD that need J's call before they can start.

Until phase 9 exit criterion is met, do not claim "production-ready" on customer-facing surfaces. Internal substrate (Lance, sidecar drop, parity probes) is solid; subject-of-record audit story is not.

VISION — what we're actually building (not what's done)

J's framing for the legacy staffing company:

• Pull live data, anticipate contracts based on Chicago permits → real architect/contractor associations, headcount, time period, money, scope.
• Hybrid + memory index → search large corpora cheaply.
• Email comes in → verify against contract; SMS comes in → alert when index changes.
• Real-time.
• Invent metrics nobody else has using the hybrid index.
• Next stage: workers download an app → geolocation clock-in → automatic responsiveness measurement, no user effort, with incentives for using it.
• Find people getting certificates (passive cert tracking).
• Pull union data → bring contracts that work for employees, not just employers.
• All metrics visible, nothing hidden, value-aligned with what each side actually needs.

If a future session is shaving away from this vision toward "fix the cutover" or "land Phase X," the vision wins. Phases are scaffolding for the vision, not the goal.

---

CURRENT PLAN — fix the demo for the legacy staffing client

Built from playwright audit of the live demo (2026-04-27 evening). Each item ends in something the client can SEE, not internal cleanups.

Demo state is anchored by git tag demo-2026-04-27 (commit ed57eda, the merge of PR #11). To restore code state: git checkout demo-2026-04-27. To restore runtime state: DELETE /catalog/datasets/by-name/client_workerskjkk (catalog hot-fix is not in git).

P1 — Search box that actually filters (highest visible impact)

Problem: typing in #sq and pressing Enter fires POST /intelligence/chat with body {"message":"<query>"}. The state (#sst) and role (#srl) selects are ignored — never sent in the body. So every search returns a generic chat completion, never a SQL+vector hybrid filter against workers_500k. That is the "cached/generic response" the client sees.

Fix: in mcp-server/search.html, change the search-submit handler to call the real worker search endpoint with {query, state, role, top_k}. The MCP search_workers tool surface already exists; route the form there. Render returned worker rows in the existing card grid.

Done when: typing "forklift" + state IL + role "Forklift Operator" returns ≤ top_k IL Forklift Operators, and changing state to WI returns different workers.

P2 — Contractor-name click → /contractor profile page

Problem: clicking a contractor name in any rendered card stays on /lakehouse/. URL doesn't change.

Fix: wrap contractor names in <a href="/contractor?name=<encoded>">. The page mcp-server/contractor.html (14.8 KB, "Contractor Profile · Staffing Co-Pilot") already exists at /contractor and the data endpoint /intelligence/contractor_profile already returns rich data.

Then check contractor.html actually shows: full history of every record the database has on that contractor + heat map of locations underneath + relevant info (per J 2026-04-27). If the page is incomplete, finish it. Otherwise just wire the link.

Done when: clicking "KACPRZYNSKI, ANDY" opens a profile with: every Chicago permit they're contact_1 or contact_2 on, a leaflet map with markers for each address, and any matched workers from prior placements at their sites.

P3 — Substrate signal at the bottom shows the right numbers

Problem: J reports the bottom panel says "playbook memory empty, 80 traces 0 replies." Reality from the live endpoints: /api/vectors/playbook_memory/stats = 4,701 entries with embeddings; /vectors/pathway/stats = 88 traces, 11/11 replays.

Fix: find the renderer in search.html that builds the substrate signal panel; verify it's hitting the right endpoints and reading the right keys; fix shape mismatches.

Done when: bottom panel shows real numbers (4,701 playbooks, 88 traces, 11/11 replays) and references at least one specific recent operation from the playbook stats sample.

P4 — Top nav reflects today's architecture

Problem: Walkthrough/Architecture/Spec/Onboard/Alerts/Workspaces tabs all return 200 but content is from old architecture. Doesn't mention: gateway scratchpad, memory indexer, ranker, mode runner, OpenCode 40-model fleet, distillation substrate, auditor cross-lineage.

Fix: rewrite mcp-server/proof.html (or add a single new page "What's running" that replaces Architecture+Spec) to describe what's actually shipped as of demo-2026-04-27. Keep one architecture page, drop redundancy. Either complete or hide Onboard/Alerts/Workspaces — J's call which.

Done when: the architecture page tells a non-technical reader, in 2 minutes, what each piece does in coordinator-relatable terms ("intern that read every email", not "3-stage adversarial inference pipeline").

P5 — Caching for the project-index build_signal (J flagged unfinished)

Problem: "we never finished our caching for project index build signal it's not pulling new information." Need to find what build_signal refers to. Likely a scrum/auditor signal that should rebuild the lakehouse_arch_v1 corpus on commit but isn't wired to.

Fix: identify the build-signal pipeline (likely in auditor/ or crates/vectord/), wire its emit to a corpus rebuild, verify by making a test commit and watching the new chunk appear in /vectors/indexes for lakehouse_arch_v1.

Done when: committing a new file to crates/ causes lakehouse_arch_v1 chunk_count to increase within N minutes.

P0 — Anchor the demo state (DONE)

EXECUTION ORDER

1. P1 first — biggest visible bug, ~30-60 min
2. P2 next — contractor click is the second-biggest "doesn't work" the client sees, ~20 min if profile is mostly done
3. P3 — small fix, big "looks alive" win
4. P4 — biggest scope; might split across sessions
5. P5 — feature work, only after the visible bugs are fixed

Each item commits independently with the format demo: P<n> — <one-line> so the commit log doubles as a progress journal. After each merge to main, re-tag demo-latest to point at the new HEAD.

Stop here and let J pick which item to start with. Do not silently extend scope.
