+## Leg 2 — slice 1: `authService.ts` core migration (commit `e37148c`)
+
+**What I did:** migrated `src/server/sessions/authService.ts` off the removed
+`AuthStorage` / `ModelRegistry.create` surface onto the async `ModelRuntime`
+API, and propagated the async construction into the session daemon.
+
+- `authService.ts`:
+ - Imports `ModelRuntime` from `@earendil-works/pi-coding-agent` and
+ `AuthInteraction` (type) from `@earendil-works/pi-ai`. Dropped
+ `AuthStorage` / `ModelRegistry`.
+ - `createModelRegistryForAgentDir` → `createModelRuntimeForAgentDir(agentDir)`
+ returning `ModelRuntime.create({ authPath:
/auth.json, modelsPath:
+ /models.json })`.
+ - Construction is now async: private constructor + static
+ `AuthService.create({ agentDir? | runtime? | authFlows? })`. `runtime` dep
+ replaces the old `modelRegistry` dep; no-agentDir fallback is
+ `ModelRuntime.create({})`.
+ - Public field `readonly runtime: ModelRuntime` replaces `modelRegistry`.
+ - `saveApiKey` → `runtime.login(providerId, "api_key", interaction)` where
+ `interaction` is a non-interactive `AuthInteraction` (`prompt: async () =>
+ key`, `notify: () => {}`). Verified against pi-ai `envApiKeyAuth().login`,
+ which calls `interaction.prompt({ type: "secret" })` and persists the
+ returned `{ type:"api_key", key }` through `credentials.modify` inside
+ `Models.login`. This is the credential-persistence path the assessment
+ (§5.1) called for.
+ - `logoutProvider` → `await runtime.logout(providerId)`.
+ - `refreshAuthState` → `await runtime.refresh()` (no more `authStorage.reload()`
+ — the file store is re-read by the runtime). Now async.
+ - `authProviders` and `requireOAuthLoginProvider` became async, awaiting
+ `runtime.refresh()` and the now-async `getLogin/LogoutProviderOptions`.
+ - `startOAuthLogin` passes `runtime: this.runtime` into
+ `OAuthLoginFlowService.start` (slice 3 will consume it via `runtime.login`).
+- `sessiond.ts`: `createRuntime()` is now `async`; `new AuthService(...)` →
+ `await AuthService.create({ agentDir })`; `PiSessionService` now receives
+ `modelRuntime: auth.runtime` instead of `modelRegistry: auth.modelRegistry`.
+- `sessiond/sessionDaemonStartup.ts`: `createRuntime` may now return
+ `Runtime | Promise` and `runSessionDaemonStartup` `await`s it. The
+ existing sync test doubles still satisfy the widened type.
+
+**Decisions:**
+- **saveApiKey via `runtime.login("api_key", …)`** rather than reaching for a
+ raw `CredentialStore.modify`: the pi-ai `CredentialStore` is not exposed off
+ `ModelRuntime` publicly, and the provider's own api-key `login` is the
+ intended persistence entry point (it writes through `credentials.modify`).
+ Feeding the key back through a non-interactive `AuthInteraction.prompt` keeps
+ us on the supported public surface. This matches assessment §5.1's
+ "credential persistence via the pi-ai CredentialStore.modify path" without
+ depending on unexported internals.
+- Kept `AuthService` construction async via a static factory (private ctor)
+ rather than an `init()` method — cleaner async boundary, single valid
+ construction path (code-quality-architecture skill).
+- Did NOT touch `authProviderOptions.ts`, `oauthLoginFlowService.ts`,
+ `piSessionService.ts`, or any test/support files — strictly slice 1 scope.
+ The async call sites I introduced (`await getLoginProviderOptions(...)`,
+ `runtime:` in `authFlows.start`, `modelRuntime:` in PiSessionService deps)
+ deliberately point at the interfaces slices 2–4 will expose.
+
+**Typecheck state:** `npx tsc --noEmit` = 31 errors (was 24 at slice 0). The
+increase is expected and honest: the migrated authService now calls
+runtime-based interfaces that slices 2/3/4 have not migrated yet. All remaining
+`authService.ts` / `sessiond.ts` errors are cross-slice (authProviderOptions
+shape → slice 2; OAuthLoginFlowService.start `runtime` param → slice 3;
+`PiSessionServiceDependencies.modelRuntime` → slice 4). Test/support files
+(slice 5) still import the removed `AuthStorage`.
+
+**Artifacts changed:** `src/server/sessions/authService.ts`,
+`src/server/sessiond.ts`, `src/server/sessiond/sessionDaemonStartup.ts`
+(commit `e37148c`); `relays/issue-62-authstorage/{status,log}.md`.
+
+**Status update:** last completed leg 2, next leg 3 = charter slice 2
+(`authProviderOptions.ts` migration).
+
+**Blockers:** none. **Sessiond restart now ACTIVE-pending** — slice 1 changed
+`sessiond.ts` and the daemon auth construction path; the human must manually
+restart the sessiond service once the migration lands (noted in status.md).
+Also: human confirmed `/tmp` is usable again, so the `TMPDIR` install
+workaround is no longer required (status.md updated).
+
+**Handoff:** spawning leg 3 (slice 2).

# Relay status — issue-62-authstorage
## Current position
-Bootstrap (slice 0) complete and committed (`0fa9d0e`). Deps are installed in the
-worktree at **0.80.10** (all three `@earendil-works/*`), `package.json` ranges
-corrected, and the new export surface is confirmed resolvable
-(`ModelRuntime`, `readStoredCredential` present; `AuthStorage` gone; pi-ai
-`InMemoryCredentialStore` present). `npx tsc --noEmit` now reports **24 errors**,
-all in `src/server/sessions/` at the expected migration sites (no crash — the
-removed `AuthStorage` import and `ModelRegistry.create/inMemory` calls). The
-migration itself has not started.
+Slice 1 (`authService.ts` core migration) complete and committed (`e37148c`).
+`authService.ts` now uses the async `ModelRuntime` API: `AuthService.create({
+agentDir | runtime })` factory wraps `ModelRuntime.create({ authPath,
+modelsPath })`; `createModelRuntimeForAgentDir` replaces
+`createModelRegistryForAgentDir`. `saveApiKey` → `runtime.login(id, "api_key",
+nonInteractive)`, `logoutProvider` → `runtime.logout`, `refreshAuthState` →
+`await runtime.refresh()`. `authProviders` / `requireOAuthLoginProvider` are now
+async. `startOAuthLogin` passes `runtime` into `OAuthLoginFlowService.start`.
+`sessiond.ts` uses async `createRuntime`, `AuthService.create`, and passes
+`modelRuntime: auth.runtime` to `PiSessionService`; `sessionDaemonStartup` now
+awaits `createRuntime`.
+
+`npx tsc --noEmit` reports **31 errors** (up from 24 — expected: the migrated
+authService now calls the runtime-based interfaces that slices 2–4 haven't
+exposed yet). Slice-1 files are internally consistent; every remaining error
+in `authService.ts` / `sessiond.ts` is a **cross-slice** dependency:
+- `authService.ts`: `getLoginProviderOptions/getLogoutProviderOptions` still
+ take the old `AuthProviderModelRegistry` shape (fixed in slice 2);
+ `OAuthLoginFlowService.start` still expects `authStorage` not `runtime`
+ (fixed in slice 3).
+- `sessiond.ts`: `PiSessionServiceDependencies` still expects `modelRegistry`
+ not `modelRuntime` (fixed in slice 4).
+Remaining errors otherwise live in slices 2/3/4 files and all test/support
+files (slice 5).
## Leg tracking
-- **Last completed leg:** 1 (slice 0 Bootstrap — deps + range correction).
-- **Next leg to run:** 2.
+- **Last completed leg:** 2 (slice 1 — authService.ts core migration + sessiond
+ async construction).
+- **Next leg to run:** 3.
## Next task
-Run **charter slice 1 (`authService.ts` core migration)** as leg 2:
-- Move `authService.ts` to `ModelRuntime` (async construction via
- `ModelRuntime.create({ authPath, modelsPath })`), migrate
- `saveApiKey` / `logoutProvider` / `refreshAuthState` / credential access off
- the removed `authStorage`/`ModelRegistry.create` surface (see assessment §5.1
- for the concrete mapping).
-- Propagate the now-async construction to `src/server/sessiond.ts`.
-- **Sessiond path:** this slice touches session-daemon code → note in
- status/handoff that a manual sessiond restart will be needed once landed.
-- Slice 1 depends only on slice 0 (done). The tree will still not fully
- typecheck after this leg (slices 2–4 remain); that is expected — leave an
- honest status.
+Run **charter slice 2 (`authProviderOptions.ts` migration)** as leg 3:
+- Rederive login/logout provider options from `runtime.getProviders()`
+ (`{ id, name, auth: { apiKey?, oauth? } }`) + `runtime.listCredentials()`
+ (`{ providerId, type }[]`) / `runtime.getProviderAuthStatus(id)` instead of
+ `authStorage.getOAuthProviders()/list()/get()` + `getAll()` +
+ `getProviderDisplayName()`.
+- The functions are already **called as async** from `authService.ts`
+ (`await getLoginProviderOptions(this.runtime, authType)` etc.) — make them
+ async and change their parameter type from `AuthProviderModelRegistry` to a
+ runtime-shaped interface (e.g. `AuthProviderRuntime` = `Pick` or a
+ structural equivalent). Update the structural interface + `authProviderOptions.test.ts`
+ test double accordingly.
+- See assessment §5.2 / §3.3 for the new API shapes. Provider display names come
+ from `Provider.name`; OAuth-capable providers are those with `auth.oauth`,
+ api-key providers those with `auth.apiKey` (respect the existing
+ `OAUTH_ONLY_PROVIDERS` / `isApiKeyLoginProvider` logic).
-If slice 1 is already done when you arrive, apply the charter's task-selection
-policy: pick the lowest-numbered incomplete slice (2 → 6).
+If slice 2 is already done when you arrive, apply the charter's task-selection
+policy: pick the lowest-numbered incomplete slice (3 → 6). Slices 3 and 4
+unblock the remaining `authService.ts` / `sessiond.ts` cross-slice errors.
### Build/tooling note (important for every leg)
-Installs and any native rebuild must set `TMPDIR` to a path inside the worktree,
-e.g. `TMPDIR="$PWD/.tmp-build" npm install` (remove the dir after). `/tmp` is a
-5.8G tmpfs at ~81% and node-gyp's `node-pty` build fails there with "Disk quota
-exceeded". `.tmp-build` is scratch — do not commit it. The pre-commit hook runs
-a whole-project typecheck; while the migration is incomplete, commit relay work
-with `git commit --no-verify` (the charter permits legs that aren't verify-green).
-Node: v24.18.0.
+**Update (leg 2):** the human reports `/tmp` is now fully usable again, so the
+previous `TMPDIR` workaround is no longer required — plain `npm install` should
+work. (If a disk-quota error resurfaces, fall back to
+`TMPDIR="$PWD/.tmp-build" npm install` and remove `.tmp-build` after; it is
+scratch, do not commit it.) node_modules is already installed at 0.80.10, so a
+fresh install is only needed if node_modules is cleared. The pre-commit hook
+runs a whole-project typecheck; while the migration is incomplete, commit relay
+work with `git commit --no-verify` (the charter permits legs that aren't
+verify-green). Node: v24.18.0.

## Blockers / intervention state
None. Known constraints:
-- **Sessiond restart pending** once slices touching `sessiond.ts` / session
- runtime land (starts with slice 1/leg 2) — the human must manually restart the
- sessiond service; keep this note current when it applies.
-- `/tmp` disk-quota issue is real — see the Build/tooling note above; always set
- `TMPDIR` into the worktree for installs/native rebuilds.
+- **Sessiond restart pending (ACTIVE):** slice 1 (leg 2, commit `e37148c`)
+ changed `sessiond.ts` + the session-daemon auth construction path. Per
+ AGENTS.md the human must **manually restart the sessiond service** for these
+ changes to take effect once the migration lands. Keep this note until the
+ human confirms the restart.
+- `/tmp` disk-quota issue is resolved (human confirmed usable) — see the
+ Build/tooling note above.
- node_modules is installed (gitignored) at 0.80.10; a fresh `npm install` is
only needed if node_modules is cleared.
