 - If no compatible background server is registered, `bun dev api` starts one through the daemon service. Use `bun dev service status`, `bun dev service restart`, and `bun dev service stop` when you need explicit lifecycle control.
 - Prefer raw method/path calls for quick server debugging and operation IDs when exercising documented OpenAPI routes with path or query parameters.
 
+## Auditing installed `opencode2` sessions
+
+Installed next-channel sessions normally use `~/.local/share/opencode/opencode-next.db` and `~/.local/share/opencode/log/opencode.log`; `OPENCODE_DB` can override the database. Before calling `opencode2 api`, inspect `~/.local/state/opencode/service.json` because the command may start a daemon when none is healthy.
+
+For a supplied `ses_...` ID, compare three sources:
+
+- `opencode2 api get /api/session/active` and the Session/message endpoints for live server state.
+- The database's ordered `event` rows for durable history.
+- `packages/tui/src/context/data.tsx` and the relevant route for client projection and rendering.
+
+Locate an uncertain database without modifying it:
+
+```bash
+SESSION=ses_...
+for db in ~/.local/share/opencode/*.db; do
+  sqlite3 "file:$db?mode=ro" "select 1 from session where id='$SESSION' limit 1" 2>/dev/null | grep -q 1 && printf '%s\n' "$db"
+done
+```
+
 ## Logs
 
 - Log files live under `~/.local/share/opencode/log/`. In a local/dev checkout the active file is `opencode-local.log`; `opencode.log` is used for non-local (released) channel installs. Both are append-only, shared across every CLI and server process on the machine.

 ## V2 Session Core
 
+- Keep durable events minimal: record irreducible new facts and do not repeat state derivable by folding the ordered aggregate history. Enrich projections and read models with previous or derived state when consumers need self-contained views.
 - Keep durable prompt admission separate from model execution. `SessionV2.prompt(...)` admits one durable `session_input` row before scheduling advisory `SessionExecution.wake(sessionID)` unless `resume: false` requests admit-only behavior. The serialized runner promotes admitted inputs into visible user messages at safe boundaries.
 - Reusing a Session ID adopts the existing Session. Reusing a prompt message ID reconciles an exact retry only when Session, prompt, and delivery mode match; conflicting reuse fails. Historical projected prompts lazily synthesize promoted inbox records during exact retry.
 - Keep `SessionExecution` process-global and Session-ID based. Its local implementation owns the process-local Session coordinator and discovers placement through `SessionStore` plus `LocationServiceMap.get(session.location)` only when a drain starts; no layer should take a Session ID. V2 interruption targets the active process-local ownership chain for that Session; idle or missing interruption is a no-op.

 ## Future Design Notes
 
 - If a captured user-visible output channel returns (an earlier `output.text`/`output.file`/`output.image` API was removed from v1), keep `output` as its name, distinct from the program return value: `return` stays the structured result for the model, while `output.*` describes artifacts the host may render into a conversation or UI after execution. Keep this host-neutral and let applications decide how captured output is delivered. In v1, hosts collect media host-side (outside the sandbox) instead.

+### OpenAPI tools
+
+`OpenAPI.fromSpec` turns an OpenAPI 3.x document into a tool subtree - one tool per operation. Dotted `operationId` values form namespaces such as `v2.session.get`. Missing IDs receive a flat method/path fallback such as `getUsersById`; names are sanitized and deduplicated. The host places the subtree under a key in its `tools` tree; that key is the model-visible namespace.
+
+```ts
+import { CodeMode, OpenAPI } from "@opencode-ai/codemode"
+import { Effect } from "effect"
+import { FetchHttpClient } from "effect/unstable/http"
+
+const api = OpenAPI.fromSpec({
+  spec: await Bun.file("openapi.json").json(), // parsed document (no YAML)
+  auth: {
+    resolve: ({ name, scopes, operation }) =>
+      name === "BearerAuth" ? Effect.succeed({ type: "bearer", token }) : Effect.succeed(undefined),
+  },
+})
+
+const runtime = CodeMode.make({ tools: { opencode: api.tools } })
+const result = await Effect.runPromise(runtime.execute(code).pipe(Effect.provide(FetchHttpClient.layer)))
+```
+
+`fromSpec` is synchronous and returns `{ tools, skipped }`. The initial adapter supports query `form`/`deepObject`, path/header `simple`, JSON request bodies, JSON responses, and text responses; unsupported parameter encodings, non-JSON request bodies, binary responses, and streaming operations land in `skipped` instead of producing broken tools. Operation and path servers take precedence over document servers unless `baseUrl` explicitly overrides all of them. Tool inputs flatten path, query, header, and closed object-body fields into one model-facing object while retaining their HTTP locations internally. Cross-location name collisions receive a location prefix such as `path_id` and `query_id`; composed, nullable, dictionary, conditionally-required, and non-object JSON bodies remain under `body`. Auth is never model-visible. Responses are limited to 50 MiB, and non-2xx responses become safe tool failures carrying the status and a size-capped body summary. Deferred capabilities are tracked in `src/openapi/TODO.md`.
+
+Supported bearer, basic, header, and query authentication follows OpenAPI `security` semantics and is resolved host-side via `auth.resolve` - credential storage, OAuth flows, and token refresh never enter the compiler. Cookie authentication alternatives are discarded; an operation is skipped when it has no supported alternative. See the option docstrings in `src/openapi/types.ts` for the full semantics. Generated tools require `HttpClient.HttpClient` (from `effect/unstable/http`) in the Effect environment - provide `FetchHttpClient.layer` or a custom/test client layer at execution. The supplied client owns redirect policy; credentialed hosts should reject redirects or strip credentials when the origin changes.

 ## Discovery
 
 The agent-tool instructions use a budgeted catalog. Every tool namespace is always listed with its tool count regardless of budget, and as many complete tool signatures (each with a one-line description) as fit an estimated-token budget are inlined. Selection is round-robin across namespaces for fairness: in each round (namespaces alphabetical), every namespace still holding un-inlined tools attempts to place its next-cheapest signature line against the shared budget, and a namespace whose next line does not fit drops out while the others keep going - so every namespace gets some representation before any namespace gets everything. The instructions state exactly how comprehensive the list is, both overall (`COMPLETE list` vs `PARTIAL - N of M shown`) and per namespace (`(3 tools)`, `(3 tools, 1 shown)`, `(3 tools, none shown)`).

+# OpenAPI Follow-ups
+
+The initial adapter intentionally skips operations it cannot execute correctly. Future work may add:
+
+- Cookie parameters, authentication, and cookie-header merging.
+- Matrix, label, space-delimited, pipe-delimited, `allowReserved`, and parameter `content` serialization.
+- External references and complete nested `$defs` support.
+- Relative or templated server URLs and server variables.
+- Base URLs containing query strings or fragments.
+- Runtime response-schema validation and full content negotiation.
+- Binary response values and explicit byte-oriented return types.
+- Request/response projection for `readOnly` and `writeOnly` properties.
+- SSE, WebSocket, and other streaming transports.
+- Recovery of responses rejected by a status-filtering `HttpClient`.
+- Configurable request and response size limits.
+- Adapter-enforced redirect policy independent of the supplied `HttpClient`.
+- Strict UTF-8 and empty-body validation for JSON responses.
+- Compile-time rejection of parameter schemas with nested values unsupported by their serialization style; runtime rejects them before auth resolution.
+- Complete malformed-security-scheme validation and broader auth-combination coverage.
