vh 9fade55901 feat(local_agents): tier-3 index + picker merge (v0.8.0)
Worldtree's GET /agents doesn't return consumer-defined (tier-3)
agents — the public list excludes them by design. Confirmed live in
v0.7.0's smoke. Without server-side knowledge, ratatoskr's picker
couldn't show tier-3 agents the operator had defined; the workflow
was "remember the agent_id, pass --agent ratatoskr:<name>
explicitly." Friction grows with every tier-3 agent.

## Fix: client-side index, merged at picker time

New module `ratatoskr.local_agents` maintains a JSON-backed index at
$XDG_CONFIG_HOME/ratatoskr/local_agents.json (override via
$RATATOSKR_LOCAL_AGENTS). `tier3` CLI define / patch / delete update
the index as side-effects. `tui._resolve_then_run` loads the index
after `list_agents(client)` and appends entries not already in the
remote list (dedup by agent_id; remote wins on conflict).

Library-level `tier3.define_agent` / `patch_agent` / `delete_agent`
stay pure — local persistence lives in the CLI layer (`_run_define`
etc.), not in the library functions. Tests of the library don't
touch the filesystem.

## Public surface

  ratatoskr.local_agents:
    LocalAgentEntry (frozen dataclass)
    load_local_agents() -> list[LocalAgentEntry]
    add_local_agent(entry)
    update_local_agent(entry)  # same semantics as add (agent_id key)
    remove_local_agent(agent_id)
    make_description(system_prompt) -> str  # synthetic picker label

Failure modes are lenient: missing file → empty index; corrupt JSON
or schema mismatch → empty index (no crash). The picker continues
to show foundational agents either way; tier-3 surface degrades to
the pre-v0.8.0 workflow.

## Picker integration

Local entries convert to ratatoskr.sessions.AgentInfo with synthetic
fields:
  name        = agent_name (from LocalAgentEntry)
  description = "(tier 3) <first non-empty line of system prompt>"
  version, capabilities, supported_models, persona_traits, ui_hints
    = None / [] / [] / {} / {}

If Worldtree later starts returning tier-3 in GET /agents, this
module's role narrows to redundant local cache; can be removed
cleanly since the dedup-by-agent-id keeps remote-wins behavior.

## Tests

286/286 GREEN (was 265, +21: 20 local_agents + 1 picker-merge
integration). Ruff clean. Tests isolate the index via
$RATATOSKR_LOCAL_AGENTS pointed at pytest's tmp_path — no pollution
of operator's real ~/.config/ratatoskr/.

## Manual smoke

Sindra-like define against personal Worldtree:
  python -m ratatoskr.tier3 define --name foo --system-prompt "..." --model X
  cat ~/.config/ratatoskr/local_agents.json
  # ratatoskr --new picker now shows ratatoskr:foo alongside mimir et al.

Cross-machine: the file is per-host. Operator can sync via dotfiles
if needed; out of scope for this commit.

Minor bump (v0.7.1 → v0.8.0) — new public module + new picker
behavior (more agents shown). No caller-side breaking changes.

vh c086ae2b32 feat(tier3): ratatoskr.tier3 module + CLI (v0.7.0)
Issue #15. Worldtree Phase 2.0 ships Tier 3 (consumer-defined)
agents at `<user_id>:<agent_name>`; ratatoskr now exposes their
lifecycle via a dedicated module + CLI tool. The picker handles
the colon-containing agent_id generically (per issue #8 out-of-
scope clause); session creation works unchanged. What was missing
was a way to DEFINE / PATCH / DELETE these agents from ratatoskr
itself — operators previously had to curl the API directly.

## Public surface (ratatoskr.tier3)

  Tier3AgentInfo (frozen dataclass)
  define_agent (client, *, agent_name, system_prompt, model) → Info
  patch_agent  (client, agent_id, *, system_prompt?, model?) → Info
  delete_agent (client, agent_id) → None

  Tier3QuotaExceeded     — 429 agent_quota_exceeded (50-agent cap)
  Tier3UserIdUnsupported — 403 tier3_user_id_unsupported
  Tier3FieldNotMutable   — 422 field_not_mutable (PATCH)
  Tier3LayerDeferred     — 422 layer_deferred (define, defense-only)
  Tier3AgentNotFound     — 404
  SessionApiFailed (reused) — all other non-2xx

Caller-owned httpx.AsyncClient posture (same as ratatoskr.sessions).
Module is standalone — does NOT import sessions/sse_client/tui/cli
beyond reusing the USER_AGENT constant from cli.

## CLI (python -m ratatoskr.tier3 <subcommand>)

  define --name <slug> --system-prompt <str> --model <id>
  patch  <agent_id> [--system-prompt <str>] [--model <id>]
  delete <agent_id>

Auth resolution mirrors ratatoskr.cli verbatim — --api-key flag >
$WORLDTREE_API_KEY > exit 11. Server URL via --server >
$WORLDTREE_API_URL > http://localhost:8000. Exit codes follow the
cli.py matrix: 0 / 10 (usage) / 11 (auth) / 20 (api-failure) / 21
(network).

## Real-world finding from live smoke

Tier-3 agents do NOT appear in `GET /agents` — the public list
filters them out. The picker won't surface tier-3 agents; operators
bypass it via `ratatoskr --send "..." --new --agent ratatoskr:<n>`
directly. This contradicts the contract's acceptance assumption
("the new tier-3 agent should appear in the list") — caught at
smoke time. The picker integration was hopeful; the real shape is
"you know your tier-3 agent_id because you defined it." Adding a
ratatoskr-side `tier3 list` subcommand would need a Worldtree
endpoint that doesn't exist today; surfacing to worldtree-dev as a
followup.

## Live lifecycle smoke (personal Worldtree v0.16.2)

  $ python -m ratatoskr.tier3 define --name smoke-tier3 \
      --system-prompt "..." --model qwen3.6-35-a3b
  → defined ratatoskr:smoke-tier3 (qwen3.6-35-a3b)

  $ ratatoskr --send "hello via tier-3" --new --agent ratatoskr:smoke-tier3
  → [done] turn_id=286 model=qwen3.6-35-a3b duration=14.2s
    usage 44 in → 390 out (434 total, 0 cached)

  $ python -m ratatoskr.tier3 delete ratatoskr:smoke-tier3
  → deleted ratatoskr:smoke-tier3

  $ python -m ratatoskr.tier3 delete ratatoskr:smoke-tier3
  → [agent_not_found] ratatoskr:smoke-tier3 (exit 20)

The colon-containing agent_id flowed transparently through
ratatoskr.sessions.create_session, the SSE stream's text +
worker_phase + done events all rendered correctly, and the
ratatoskr.sessions module needed zero changes.

## Contract

docs/contracts/issues/15.contract.md — new module spec; drift-check
clean. Acceptance criterion about "appears in GET /agents" should be
amended in a follow-up to reflect the empirical finding.

## Tests

+26 tests (264 total GREEN, was 238). Covers all error paths via
respx mocking — quota, user_id, layer_deferred, field_not_mutable,
404, 5xx — plus CLI happy + error paths. ruff clean.

Minor bump (v0.6.5 → v0.7.0) per SemVer etiquette: new public
module + CLI surface; new caller-visible behavior.
