Search port + model slots wave, chunk A (owner design, 2026-09-20):
- core/search.ts: SearchHit + SearchProvider port + SearchStatus —
pure, browser-safe; adapters arrive as injected dependencies.
- server/search.ts: Tavily + Brave adapters (wire shapes VERIFIED
against docs.tavily.com's OpenAPI + Brave's dashboard docs — Tavily
auth is the Bearer header, not the legacy body api_key; Brave is
X-Subscription-Token) + engine resolution per owner decisions: a key
ALONE activates its engine (no engine choice needed), explicit
agent.search.engine pins the preference (both keys: Tavily first),
a pinned engine with a missing key is honestly unavailable — no
silent fallback, no default engine.
- Curated keys catalog: GOOGLE_SEARCH_API_KEY/GOOGLE_CSE_ID retire
(CSE closed to new customers, dies Jan 2027 — stored values become
preserved unknown vars); TAVILY_API_KEY (tvly- shape) + BRAVE_API_KEY
(length guard) join. UI keys-section TOOL_IDS now derives from the
catalog — cannot drift.
- GET /api/search: {available, engine, reason} — the honest status for
the settings gray-out; researcher-disable semantics ride the same
signal (Teacher stream rewires the tool onto the port).
- agent.search settings field (schema + sanitizer + strict parser);
web.ts's WebSearchResult is now the core SearchHit (re-exported).

/**
|
|
* The search-provider port (search port + model slots wave, 2026-09-20).
|
|
*
|
|
* Search engines are pluggable behind ONE seam: the settings record names a
|
|
* preferred engine (agent.search.engine — optional), keys live in the auth
|
|
* store (TAVILY_API_KEY / BRAVE_API_KEY — curated catalog), and the server
|
|
* composes the live adapter. The Google CSE engine retired with this wave
|
|
* (closed to new customers; dies Jan 2027) — replaced by Tavily + Brave.
|
|
*
|
|
* Owner decisions baked here:
|
|
* - NO default engine in the factory record: an engine is live iff its
|
|
* key is present. With a key, the engine auto-activates (the user never
|
|
* chooses an engine to make search work — setting the key is enough);
|
|
* agent.search.engine is only an explicit preference.
|
|
* - Nothing silently falls back: no engine live = search is honestly
|
|
* unavailable (the tool says so; the researcher sub-agent is disabled
|
|
* by the agent layer on the same signal — that rewiring is the Teacher
|
|
* stream's, on this port).
|
|
*
|
|
* Pure types + protocol docs only (browser-safe, no node imports): the
|
|
* adapters are server-side (src/server/search.ts) and arrive as injected
|
|
* dependencies — the agent-layer tool depends on THIS port only.
