Separate what a worker does from what a company needs filled

Owliver could offer neither create. The Create Position flow worked and no chip
anywhere suggested it, because the chip row is entirely the backend's static
catalogue and no intent in it wrote anything. The gap was never in the
frontend's trigger matching — every phrasing already routed.

`employee_roles` is the supply side of `job_postings`. A posting is what the
ORGANIZATION needs filled; this is what a WORKER says they do. They share a
vocabulary and almost nothing else: "3 years" on a posting is a minimum an
applicant must clear, and the same words here are what the person has. There is
deliberately no foreign key between them — supply and demand already meet
through `job_applications`, which carries the funnel, the interview and the
outcome, and a second weaker link would disagree with it the first time
somebody withdrew.

NO NEW COMPANY ENTITY, AND THAT IS THE LOAD-BEARING DECISION. "Create a company
position" reads like it needs a client record. `organizations` is the TENANT —
absent from the resource table, absent from the policy map, written only by the
seeder — so creating a row there from a chat flow would provision a new tenant,
and the position would carry an org_id the operator's session cannot see. The
operator could never view the record they just created. That breaks I5 and I1
to add a feature nobody asked for. The client stays free text on the posting,
per blueprint decision D2, and the flow simply offers the clients this
organization already staffs for as chips. No schema change, no endpoint change.

Create is operators-only, and that is an I1 decision rather than a deferral.
The worker is named explicitly on the row and is deliberately NOT derived from
the session, because an operator recording a role on somebody's behalf is the
whole point of the flow. Granting talent the same Create would let a talent
caller write a role under any worker_email in the tenant — the attribution hole
Phase 3D closed elsewhere. Talent reads its own via a ScopeEmail predicate,
which is in place now so the grant is one line when a talent console exists.

`created_by` is in gen_resources.py's SERVER_OWNED as well as the policy's
Derived list. Both are required and the pairing is easy to miss: Derived fills
the column from the session, SERVER_OWNED is what makes the descriptor ReadOnly
so a request body cannot set it in the first place. Without it,
TestDerivedColumnsAreReadOnlyOrTalentScoped fails — verified by mutation, not
by reading.

The two catalogue intents carry PHRASE terms only. A bare "position" or "role"
term scores 10, the same as every reading on that page, and wins the tie on
declaration order — so a create chip would have arrived by evicting
`positions-attention` from the exact ordered result TestPositionsSuggestions
asserts. An offer to create something must not displace the reading a person
actually asked for. Neither declares a Subject, on the precedent of
`position-spec-steps`: a Subject would let the bare query "summarize" match
through matchShape and survive filterOnTopic. Neither declares a Signal, so an
empty composer still reports what the organization needs rather than proposing
paperwork.

Chip text is the coupling with nothing else holding it together: no page
context declares `capabilities`, so every server suggestion dispatches as its
own TEXT and is answered by whichever skill's trigger that text matches. A
renamed chip would open nothing, silently. Asserted on the frontend side.

The down migration drops `employee_role_status` and keeps `english_level`,
which is shared with job_postings.english_required and
job_applications.english_level. Rolled back and re-applied against the
database to prove it, not asserted.

+
+---
+
+## Changing model provider
+
+The gateway speaks two wire protocols. `anthropic` is the Claude API.
+`openai` is the chat-completions shape — and that one is not only OpenAI:
+Groq, Gemini's compatibility endpoint, OpenRouter, Together, vLLM and a local
+Ollama all serve it, so moving between them is configuration, not code.
+
+```bash
+# Groq
+MODEL_PROVIDER=openai
+MODEL_BASE_URL=https://api.groq.com/openai/v1
+MODEL_API_KEY=<key>
+MODEL_FAST=llama-3.1-8b-instant
+MODEL_BALANCED=openai/gpt-oss-120b
+MODEL_DEEP=openai/gpt-oss-120b
+
+# Gemini
+MODEL_BASE_URL=https://generativelanguage.googleapis.com/v1beta/openai
+
+# A model on this machine — no credential at all
+MODEL_BASE_URL=http://localhost:11434/v1
+```
+
+Four things worth knowing before you do it.
+
+**Set `MODEL_PROVIDER`, not just the base URL.** The anthropic path has one
+endpoint and ignores `MODEL_BASE_URL` entirely, so setting the URL alone is a
+deployment that believes it has switched providers and has not — every run
+still goes to Anthropic and is still billed there. Config validation refuses
+that combination at startup rather than letting it run up a bill quietly.
+
+**Leave `MODEL_REASONING_EFFORT` off unless every configured model is a
+reasoning model.** Reasoning models accept the field; most others reject the
+*entire request* with a 400 rather than ignoring an unknown key.
+
+**Run the evals before trusting it, and read the I7 case first.**
+
+```bash
+MODEL_PROVIDER=openai MODEL_BASE_URL=… MODEL_API_KEY=… MODEL_BALANCED=… make eval-live
+```
+
+`liveGateway` reads the same environment the service does and logs which
+provider and model answered. The handbook corpus contains a planted prompt
+injection; Claude refuses it and reports the document as tampered with. **A
+model that answers every other case well and follows that injection is not a
+cheaper option — it is a security regression.** That case is the gate, not the
+cost table.
+
+**Token accounting differs between the two wires and is already reconciled.**
+OpenAI reports `prompt_tokens` *inclusive* of the cached prefix; Anthropic
+reports input tokens *exclusive* of it. `oaiUsage.normalise` subtracts, because
+`Usage.Total()` sums all four fields and copying both numbers across verbatim
+would bill the cached prefix twice — worst on long conversations, which is
+exactly where I3's budget matters most. Don't "simplify" that subtraction away;
+there is a test named after it.

 - The fixture-drift CI jobs need `FRONTEND_REPO_TOKEN` to see the sibling repo,

+  on the cluster host, registered as `krow-runner` with labels
+  `ubuntu-latest, ubuntu-22.04` mapped to `node:20-bookworm`. Before that, both
+  repositories had workflows that had never executed once — the 924 frontend
+  checks, the whole Go suite, the skip guard and the suite-shrank guard were
+  all things somebody had to remember to run.
+
+  If a job fails resolving `actions/checkout` or `actions/setup-node`, the
+  runner needs egress to github.com or a mirror; that is where those actions
+  come from and Gitea does not host them.
+- **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.

+// that nobody meaningfully changed stops a deploy.
+//
+// The comparison is deliberately conservative, because the two ways of being
+// wrong are not equally bad. Reporting a difference that does not exist blocks
+// a deploy, which is visible and recoverable. Reporting no difference when one
+// exists lets a changed agent overwrite an approved version silently, which is
+// the thing versioning is for. So anything not PROVABLY inert counts as a
+// difference:
+//
+//   - The body is compared verbatim. It is the system prompt, and Agent.Body
+//     carries `json:"-"`, so marshalling alone would ignore a complete rewrite
+//     of the instructions.
+//   - List ORDER is significant. loader.go resolves Skills in order, so the
+//     order reaches prompt assembly. Two definitions listing the same skills
+//     differently are treated as different, and a deploy that only reorders
+//     one still has to raise its version. That is a deliberate limit, not an
+//     oversight — loosening it needs someone to decide that skill order cannot
+//     matter, and that is not a decision to make inside a comparison function.

Owliver\nasks one question at a time, offers the answers as chips, and reads the whole\nthing back before anything is written.\n\n**This is not Create Position, and the difference is the point.** A position is\nwhat the ORGANIZATION needs filled — a company, a title, a pay range it will\npay. An employee role is what a WORKER says they do — the role they present\nthemselves as, the experience they have, and the pay they are looking for. The\ntwo share a vocabulary and nothing else: \"3 years\" on a position is a minimum an\napplicant must clear, and the same words here are what this person has.\n\nThey are never joined by a column. Supply and demand meet through applications,\nwhich already carry the funnel, the interview and the outcome.\n\n## Capabilities\n\n- Understand requests to record what a worker does.\n- Ask who the role is for, and resolve the answer to a real worker profile.\n- Read the role, experience, English level, certifications, desired pay and\n  availability out of a single sentence.\n- Ask only for what the request did not already answer.\n- Offer each answer as a suggestion, so the whole flow can be clicked.\n- Read the role back for confirmation before recording it.\n\n## Conversation\n\nEach line is `field | question | suggestions | required?`. Suggestions beginning\nwith `@` come from the application's own data.\n\n`@workers` is the worker profiles already on screen for this organization.\nPicking one records the role against that person's profile and email; typing an\nemail address that has no profile yet also works, because a role can be declared\nbefore a profile exists. The worker is always asked for and is never assumed to\nbe whoever is typing — an operator records this on somebody's behalf.\n\n- worker | Which worker is this role for? Type their name or email. | @workers | required\n- role_category | What role do they work as? | @roles | required\n- experience_years | How much experience do they have? | No experience; 1 year; 2 years; 3+ years | optional\n- english_level | What is their English level? | @english | optional\n- certifications | Any certifications they hold? | @certifications; None | optional\n- desired_pay | What pay are they looking for? | $18–$28/hr; $25–$35/hr; $30–$40/hr; Custom | optional\n- availability | When are they available? | @availability | optional\n- notes | Anything else worth recording? | | optional\n\n## Actions\n\n- create_employee_role"

+§6: "Delegation is a tool call from the parent's perspective. Subagent runs get
+their own trajectory, linked by parent_run_id."
+
+Everything for this existed except the delegation. The parser read `subagents:`,
+the runtime type carried them, the loader populated them, agent_runs had a
+parent_run_id column with a self-reference and a no-self-parent constraint, and
+budget.go's comments described sharing a budget with subagents. Nothing called
+any of it, so krow-workforce-agent declared five subagents and answered every
+question alone.
+
+Three rules from §3 and §6 are load-bearing here, and each is enforced below
+rather than assumed:
+
+  I1  A subagent runs as the ORIGINAL caller. It never receives a widened
+      principal, so it can read exactly what the person could read directly.
+  §6  A subagent SHARES the parent's budget. It never gets a fresh one, or a
+      run could buy itself unlimited steps by delegating in a loop.
+  §3  Depth is capped. The cap is what makes a cycle in the spec graph a
+      bounded waste rather than an unbounded one.
+──────────────────────────────────────────────────────────────────────────── */

+// MaxDelegationDepth is §3's cap.
+//
+// The root run is depth 0, so a run at depth 2 is offered no subagents at all
+// and delegation stops there. Publish-time cycle detection is the other half
+// of §3 and is not here — this is what holds when a cycle reaches run time
+// anyway, which is the case worth defending against.

+-- Krow — employee roles
+--
+-- Phase 4. The supply half of a pair whose demand half already exists.
+--
+-- WHAT THIS TABLE IS FOR
+--
+-- `job_postings` is what the organization NEEDS FILLED: a company, a title, a
+-- pay range, a set of requirements. This table is what a WORKER SAYS THEY DO:
+-- the role they present themselves as, what they have done before, what they
+-- want to be paid, and when they can work.
+--
+-- Those are two different records that happen to share a vocabulary, and
+-- collapsing them was the obvious wrong turn. A posting without a company is
+-- not a worker's role, and a worker who is available on weekends is not a
+-- vacancy. Owliver now has to create both from the same panel, so the
+-- distinction has to exist somewhere it cannot be blurred — here.
+--
+-- WHY THERE IS NO FOREIGN KEY TO job_postings
+--
+-- Supply and demand meet through `job_applications`, which already exists and
+-- already carries the funnel. A column here pointing at a posting would be a
+-- second, weaker version of that relationship — one with no status, no history
+-- and no interview attached — and the two would disagree the first time
+-- somebody withdrew.
+--
+-- WHY THE WORKER IS IDENTIFIED TWICE
+--
+-- `worker_profile_id` is the join when a profile exists; `worker_email` is the
+-- durable identity and is what the talent row-scope predicate reads. Exactly
+-- the pair `evidence` uses, and for the same reason: `worker_profiles.user_id`
+-- is itself ON DELETE SET NULL, so a profile is not a stable identifier.
+--
+-- CASCADE on the profile, matching `evidence`. A declared role orphaned to a
+-- bare email cannot be recovered — nothing else on the row says who the person
+-- was — so it goes with the profile rather than lingering as a record nobody
+-- can resolve.
+--
+-- WHAT IS DELIBERATELY ABSENT
+--
+--   a clients table          The company a position is staffed for is still
+--                            free text on job_postings, by blueprint decision
+--                            D2. This table does not name a company at all: a
+--                            worker's role is theirs, not a client's.
+--   UNIQUE on the worker     A worker may declare Bartender AND Server, and a
+--                            worker placed as a Bartender who starts seeking
+--                            again needs a second row rather than an
+--                            overwritten one. History is the point.
+--   a DELETE path            Retirement is `status = 'inactive'`. A role that
+--                            was matched against and then vanished is a record

+# Create Employee Role
+
+## Purpose
+
+Record a worker's declared professional role without leaving the page. Owliver
+asks one question at a time, offers the answers as chips, and reads the whole
+thing back before anything is written.
+
+**This is not Create Position, and the difference is the point.** A position is
+what the ORGANIZATION needs filled — a company, a title, a pay range it will
+pay. An employee role is what a WORKER says they do — the role they present
+themselves as, the experience they have, and the pay they are looking for. The
+two share a vocabulary and nothing else: "3 years" on a position is a minimum an
+applicant must clear, and the same words here are what this person has.
+
+They are never joined by a column. Supply and demand meet through applications,
+which already carry the funnel, the interview and the outcome.
+
+## Capabilities
+
+- Understand requests to record what a worker does.
+- Ask who the role is for, and resolve the answer to a real worker profile.
+- Read the role, experience, English level, certifications, desired pay and
+  availability out of a single sentence.
+- Ask only for what the request did not already answer.
+- Offer each answer as a suggestion, so the whole flow can be clicked.
+- Read the role back for confirmation before recording it.
+
+## Conversation
+
+Each line is `field | question | suggestions | required?`. Suggestions beginning
+with `@` come from the application's own data.
+
+`@workers` is the worker profiles already on screen for this organization.
+Picking one records the role against that person's profile and email; typing an
+email address that has no profile yet also works, because a role can be declared
+before a profile exists. The worker is always asked for and is never assumed to
+be whoever is typing — an operator records this on somebody's behalf.
