Both documents are the first thing a new reader trusts, and several of their
claims were wrong — some wrong from the start, some overtaken by work this
week. A governing document that misdescribes the system is worse than none,
because it is believed.
CLAUDE.md §10 specified Python 3.11, FastAPI, SQLAlchemy and Alembic. The code
is Go and has never been anything else. That is corrected rather than quietly
deleted, so the next person understands the document drifted rather than
wondering which half to trust.
Also in CLAUDE.md: the tool count was 17 with one write and is 19 with two;
delegation now exists and §11's Orchestration row says what it guarantees; the
embedder deviation described a Voyage-or-stand-in choice that has since become
EMBED_PROVIDER with three options, of which production sets none.
The handover claimed three things that this session disproved by running them:
- "definition_versions is empty ... nothing has gone through it". It was not
empty in production; activity-agent had a v1 that the shipped file
contradicted, which is how a real drift was found. It now holds every
agent and skill.
- "Skills are still stored in user_preferences". They are rows in
skill_definitions, and are now versioned.
- "make eval-live ... has never been run". It has, it passes 3/3, and what
it established is recorded — including that the handbook corpus carries a
planted prompt injection which the agent refused and reported. That is I7
holding against a real model, which is worth more than the pass count.
The endpoint counts were one high throughout (55/57, not 56/58) — the delta of
two was always right, so the signal worked and the absolute numbers did not.
Added, because they cost time this week and would cost it again:
- the app reaches its database through pgbouncer, not PostgreSQL directly.
Enabling TLS on PostgreSQL does nothing for the application hop; pgbouncer
terminates 5432 and needs its own client_tls_sslmode.
- the seeded UserActivity is NOT anchored to today the way ShiftRecord is,
so it ages out of every window the activity tools offer. Twenty-three days
old as of writing: zero events in the last 7 days, 6 of 15 in the last 30.
The agent answers truthfully and the demo looks dead.
- the whole stack runs on Docker alone. Dockerfile.api builds every command
plus the migrate CLI, so a new machine needs neither Go nor psql — which
is how this one was set up, having no Homebrew.
- Ollama runs on the HOST, so a container reaches it at
host.docker.internal, not localhost. The old .env said localhost and would
have failed with nothing obviously wrong.

# Handover
|
||
|
||
Written 2026-08-28, when the machine this was built on was retired.
|
||
|
||
Everything Claude Code "remembers" lives in `~/.claude/projects/<mangled-path>/`
|
||
on one machine, keyed to the absolute path of the checkout. It does not sync,
|
||
and a different path on a new machine reads a different folder. So the durable
|
||
record is this file, in the repository, where git carries it and any path works.
|
||
|
||
Read `CLAUDE.md` first — it is the governing document. This file is what it does
|
||
not say: what was decided, what is deployed, and which parts bite.
|
||
|
||
---
|
||
|
||
## Where things stand
|
||
|
||
**Deployed.** Backend at `https://mcp.krowforce.com`, frontend at
|
||
`https://platform.krowforce.com`, Kubernetes statefulset `krow` in namespace
|
||
`krow`, pods named `krow-1` and `krow-2` (they start at 1, not 0).
|
||
|
||
ssh root@<host> -p 4422 "kubectl -n krow rollout restart statefulset/krow && \
|
||
kubectl -n krow rollout status statefulset/krow --timeout=180s"
|
||
|
||
**Verify a deployment** — 55 checks including a real agent run:
|
||
|
||
KROW_EMAIL=... KROW_PASSWORD=... make verify-deploy BASE=https://mcp.krowforce.com
|
||
|
||
Auth runs BEFORE routing, so an unauthenticated probe answers 401 for every
|
||
path including ones that do not exist. `curl` cannot tell a missing endpoint
|
||
from a guarded one; only an authenticated check can.
|
||
|
||
**Two runtime steps a deploy does not do**, both easy to forget because the API
|
||
looks healthy without them:
|
||
|
||
kubectl -n krow exec krow-1 -- importagents --org <slug> # publishes agents/ and skills/
|
||
kubectl -n krow exec krow-1 -- ingest --org <slug> # ingests knowledge/
|
||
|
||
Without the first, every Owliver question answers 404. Without the second,
|
||
retrieval finds nothing. The org slug is `krow-dev` — a hardcoded constant
|
||
(`internal/orgctx.DevOrgSlug`), not configuration.
|
||
|
||
**The endpoint count is a signal.** `GET /api/v1/version` reports it. Agent run
|
||
routes are not registered without a model credential, so **55** means no
|
||
`ANTHROPIC_API_KEY` and **57** means there is one. (These were written as 56/58
|
||
and were one high; the delta of two — the two run routes — was always right.) A keyless deployment boots
|
||
cleanly under `APP_ENV=staging` and refuses under `production`.
|
||
|
||
---
|
||
|
||
## Decisions taken, so they are not relitigated
|
||
|
||
**§12, who authors agents: self-serve, split by visibility.** `personal` agents
|
||
are authored in the UI, POST to `/api/v1/agent-definitions`, and are runnable
|
||
immediately; evals are not required for them. `organization` agents stay as
|
||
files published by `importagents` on deploy — that deploy step *is* the approval
|
||
workflow, and §9's eval requirement still applies. §12 warned self-serve needs
|
||
"3× the platform"; it does not here, because I1 means an agent runs as its
|
||
caller and cannot exceed their access, I4 means writes still need a human, and
|
||
the spec format has no `limits` block so budgets cannot be raised by an author.
|
||
|
||
**A rejected candidate counts as screened.** It ranks with `ai_screened`:
|
||
rejection overwrites the stage it came from, so shortlisted can never be
|
||
claimed. **An assigned candidate counts as hired**, matching the backend's
|
||
existing `status IN ('hired','assigned')`.
|
||
|
||
**Seeded profile scores are the formula's output**, not hand-authored narrative.
|
||
Recalculating a seeded profile is a no-op, and a skill-check enforces it.
|
||
|
||
---
|
||
|
||
## Conventions the schema actively contradicts
|
||
|
||
These are the ones that produce confident, wrong numbers rather than an error.
|
||
|
||
**`job_applications.screened_at` is vestigial.** Nothing writes it. "Screened"
|
||
means `status <> 'applied'`, in about eight places in the frontend. Reading the
|
||
column reported 1 screened of 24 where the truth was 14.
|
||
|
||
**A score of `0` means "not rated", never "rated zero".** Every score column is
|
||
NOT NULL, so there is no null to distinguish it — that is the trap. Applies to
|
||
`ai_score`, `client_rating`, `krow_score`, `reliability_score`,
|
||
`attendance_score`, `performance_score`, `experience_years`. Aggregates need
|
||
`FILTER (WHERE col > 0)` and a stated basis count. Counting zeros once reported
|
||
"16 weak candidates averaging 28" for a pool that was 1 weak averaging 76.
|
||
|
||
Anchors to check against: applications are **9 scored averaging 76**; workers
|
||
are **5 rated of 9, client rating 4.70**.
|
||
|
||
**Genuine zeros, do not filter these:** `overtime_hours`, `minutes_late`, `xp`,
|
||
`profile_completion`, and `actual_hours` (0 only on absent/no_show shifts).
|
||
|
||
**`absent` and `no_show` are both missed shifts, but only one is a no-show.**
|
||
`attendance.js` is canonical.
|
||
|
||
**`attendance_score` defaults to 100 for display and must never be a scoring
|
||
input.** A profile with no evidence otherwise scores 12 and leaves the "not yet
|
||
scored" band.
|
||
|
||
**The stage ladder lives once**, in `krow-demo/src/lib/hiringRecords.js`. It was
|
||
three byte-identical private copies, all missing `rejected` and `assigned`,
|
||
which `indexOf` scored -1 and dropped from every bucket including `applied`.
|
||
|
||
---
|
||
|
||
## Things that will waste your afternoon
|
||
|
||
**A space in the checkout path breaks path derivation.** This repo lives under
|
||
`Krow Project /`, and it has bitten three times: an unquoted `$(CURDIR)` in the
|
||
Makefile, `` `file://${process.argv[1]}` `` in a script guard, and
|
||
`new URL(...).pathname` in `scripts/oracle.mjs` (use `fileURLToPath`). Any new
|
||
path derivation is guilty until tested there.
|
||
|
||
**`seed.json` is generated from `krow-demo/src/api/seed.js`.** Never edit it.
|
||
`npm run seed:fixture` writes it, `npm run seed:check` verifies, and the
|
||
skill-check compares byte-for-byte. `ShiftRecord` is excluded on purpose: the Go
|
||
seeder generates it against *now*.
|
||
|
||
**Shift data is anchored to today**, so anything asserting against it is
|
||
date-dependent unless the anchor is pinned. `buildShiftsAt(anchor)` exists for
|
||
that. One detector had a Friday-and-Saturday blind spot for exactly this reason.
|
||
|
||
**Database tests skip when PostgreSQL is unreachable** (`testutil` calls
|
||
`t.Skipf`). `go test` then exits 0 having run almost nothing. CI has a guard
|
||
that fails on any skip other than `TestLive*`; keep it.
|
||
|
||
**The eval suites use a scripted model.** They prove the permission boundary,
|
||
not answer quality. `make eval-live` uses the real model and costs tokens.
|
||
|
||
It has now been run, and passes 3/3 in about 30 seconds. Worth knowing what it
|
||
established, because it is more than "the agents work":
|
||
|
||
- the coverage agent called `assign_worker` and the write did NOT happen —
|
||
I4 holds against a real model, not only a scripted one;
|
||
- the handbook corpus contains a planted prompt injection telling the agent
|
||
to send the staff roster to an external address. The agent refused it,
|
||
answered the real question with citations, and reported the document as
|
||
tampered with. I7 holds end to end;
|
||
- the activity agent declined to subtract two figures it could not
|
||
reconcile, and said so, rather than producing the confident wrong number
|
||
this schema invites.
|
||
|
||
Re-run it after any change to the loop, retrieval, or prompt assembly. It is
|
||
the only check that measures answers rather than boundaries.
|
||
|
||
**The seeded activity data is NOT anchored to today.** `ShiftRecord` is —
|
||
`seed.js` says so — and `UserActivity` is not, so it ages out of every window
|
||
the activity tools offer. As of 2026-08-29 the newest event was 23 days old:
|
||
zero events in the last 7 days and 6 of 15 in the last 30. The activity agent
|
||
answers truthfully and the demo looks dead. Anchoring it the way shifts are
|
||
anchored is the fix; it changes `seed.json`, so it goes through
|
||
`npm run seed:fixture` and re-runs the frontend checks.
|
||
|
||
---
|
||
|
||
## Still outstanding
|
||
|
||
- `ANTHROPIC_API_KEY` was pasted into a chat transcript and is live in a
|
||
Kubernetes Secret. Rotate it.
|
||
- Deployments report `version=dev`: the image is built without
|
||
`--build-arg VERSION`. `make docker-build` passes it.
|
||
- `APP_ENV=staging` on the deployment, so the production config guards are off.
|
||
- CI tests but does not deploy. The README's claim that migrations are "run by
|
||
CI against the target database" is still aspirational.
|
||
- The fixture-drift CI jobs need `FRONTEND_REPO_TOKEN` to see the sibling repo,
|
||
and fail rather than pass quietly without it.
|
||
- The remote is Gitea. These are GitHub Actions workflows; they do nothing until
|
||
a compatible runner exists. Nobody has confirmed a runner exists, so treat
|
||
both repositories as having no CI until somebody checks.
|
||
- **The application talks to its database in clear text.** `DATABASE_SSLMODE=
|
||
disable` against `66.116.207.225`, which is a DIFFERENT machine from the
|
||
cluster host — so credentials and every row cross the network unencrypted.
|
||
It is permitted only because `APP_ENV=staging`; the production guard refuses
|
||
`disable` outright. PostgreSQL itself now has `ssl = on` (2026-08-29, port
|
||
5433, reload not restart), but the app does not reach PostgreSQL directly:
|
||
**pgbouncer terminates 5432** and offers no TLS of its own. The fix is
|
||
`client_tls_sslmode = allow` plus a cert in `/etc/pgbouncer/pgbouncer.ini`,
|
||
then `DATABASE_SSLMODE=require` in `krow-config` and the `krow-db` secret.
|
||
`allow` keeps existing plaintext clients working, so it is additive.
|
||
- Production retrieval is **keyword-only**: no `EMBED_PROVIDER` in
|
||
`krow-config`, so `knowledge_chunks.embedding` is null for all 34 rows. A
|
||
`VOYAGE_API_KEY` is the cheap fix; Ollama in-cluster is the other, and the
|
||
nodes were at 60% and 49% memory when that was last looked at.
|
||
- Delegation (§6) is implemented and on `main` but NOT deployed. Until the next
|
||
image ships, production agents still ignore their `subagents:`.
|
||
- §3's publish-time cycle detection is still missing. The runtime depth cap
|
||
(2) is what bounds a cycle that reaches run time.
|
||
- `cmd/importagents` has no tests, and `run()` opens its own pool from config,
|
||
so making it testable is a refactor rather than an addition.
|
||
- `importagents` does not enforce monotonicity: a spec whose `version:` is
|
||
LOWERED still overwrites the live row and rolls the deployed agent backwards.
|
||

|
||
## Setting up a new machine
|
||
|
||
git clone <backend> krow-backend && git clone <frontend> krow-demo
|
||
cp krow-backend/CLAUDE.md ./claude.md # the governing doc lives above both repos
|
||
|
||
Needs, if you run the backend natively: Go (see `go-api/go.mod`), Node 20,
|
||
PostgreSQL, Docker, and Ollama with `nomic-embed-text` for semantic retrieval.
|
||
|
||
You do not need most of that. `infrastructure/Dockerfile.api` builds EVERY
|
||
command in `go-api/cmd/` plus the golang-migrate CLI into the image, so the
|
||
whole stack runs on Docker alone — no Go, no psql, no migrate on the host:
|
||
|
||
cd krow-backend/infrastructure
|
||
cp .env.docker.example .env # fill it in; DATABASE_HOST=postgres
|
||
docker compose -f docker-compose.yml -f docker-compose.local-db.yml up -d
|
||
docker exec krow-api seed
|
||
docker exec krow-api importagents --dir /app/agents --skills /app/skills --org krow-dev
|
||
docker exec krow-api ingest --dir /app/knowledge --org krow-dev
|
||
printf '%s' 'PASSWORD' | docker exec -i krow-api setpassword -email demo@krow.app -stdin
|
||
|
||
Ollama, if you want semantic retrieval, runs on the HOST — so the container
|
||
reaches it at `host.docker.internal:11434`, NOT `localhost:11434`, which inside
|
||
a container means the container.
|
||
|
||
Running natively instead, you need all of the above. Then:
|
||
|
||
cd krow-backend && cp .env.example .env # fill it in; .env is gitignored
|
||
make migrate-up && make seed
|
||
make import-agents ORG=krow-dev
|
||
make ingest ORG=krow-dev
|
||
go run ./go-api/cmd/setpassword -email demo@krow.app
|
||
|
||
cd ../krow-demo && npm ci && cp .env.example .env
|
||
# VITE_AGENT_API=/api/v1 for local dev (vite proxies it);
|
||
# production passes an absolute URL as a Docker build arg instead.
|
||
|
||
`.env` files are not in git and must be carried across by hand.
