Creating or opening a session could stall for reasons the daemon knew
about and never shared. The browser invented the whole message it showed
while waiting -- "Creating session: Waiting for the backend session to be
ready" -- which says that we are waiting but never what for. A shared
ModelRuntime read during startup can be handed a network refresh that is
already in flight, and extensions may do their own network I/O while
loading, so the wait is real and previously unattributable.
The pre-session gap turned out to be a missing shared key rather than a
missing channel: publishActivity needs the PiAgentSession being built, but
the session id and cwd are both known before the first await. So create()
now publishes a new global session.startup event carrying an ordinary
SessionActivity, routed by cwd -- the one identity a browser row waiting
for a session id can match, since the client-invented pending id is
unknown to the daemon and the daemon's id is unknown to the browser.
Two phases are reported, each published before the await it describes so
the label changes during the wait rather than after it: "Starting the Pi
session" and "Loading session extensions". Both are facts, because the
service awaits exactly one call for each. A concurrent background catalog
refresh is appended as a note ("provider model lists are refreshing"),
never as the cause: the refresher can prove a refresh is running but not
that this startup joined it. ModelCatalogRefresher gains only a read-only
isRefreshInFlight() getter; cadence, timeout, and coalescing are untouched.
Reporting is event-only and synchronous. It writes no activities entry, no
workspace activity, and no unread state, so a failed creation leaves
nothing stranded, no await is added, and creation ordering and semantics
are unchanged. The window-ending idle report is skipped when a real
activity was published during startup, so an extension error survives.
The browser applies startup progress only when it can prove the target:
one non-discarded pending start in that cwd on the selected machine, or a
session whose id it already knows. A foreign workspace, another machine,
or two concurrent starts in one workspace keep today's generic wording
rather than showing one row the phase of another. An idle report restores
that generic wording, including the queued-messages variant.
docs/config.md said nothing a request triggers waits on a catalog fetch.
That is not strictly true for a refresh already in flight, so both it and
the generated docs/config.html now state the exception and say PI WEB
reports it while it happens.
The global provider bootstrap froze all three ModelRuntime mutation
methods after startup, so a provider extension that fetched an updated
model catalog had that work silently discarded.
registerProvider is now applied when the provider ID is already in the
frozen baseline and the incoming config equals the recorded baseline in
every field except `models`. Refreshing extensions re-send a complete
provider config rather than a models-only delta, so the test is
"equal except models", not "contains only models".
Everything else stays a logged no-op: unknown provider IDs, any change
to name/baseUrl/apiKey/api/streamSimple/headers/authHeader/oauth/
refreshModels, native registration, and unregistration. Function-valued
fields compare by reference and so always read as a mismatch, which is
the intended conservative direction.
An accepted update rebases the stored baseline from Pi's merged record,
so repeat refreshes work and an unchanged replay is correctly ignored
rather than re-applied on every session start. The accept path stays
synchronous and never awaits or networks; Pi's own trailing
fire-and-forget local refresh is untouched.
Bump @earendil-works/pi-coding-agent, pi-ai, and pi-agent-core to 0.82.1
together and raise the peer range to >=0.82.1 <0.83. All three must move in
lockstep: bumping only two leaves a duplicate pi-ai copy in the tree, which
surfaces as misleading type-identity errors rather than real API breaks.
Pi 0.82 removed ModelRuntime.reloadConfig() and merged it into refresh(),
which now does ModelConfig.load, configureRadiusProviders, and rebuildProviders
before refreshing. Port the five production call sites literally, passing no
options so refresh() keeps defaulting allowNetwork to modelNetworkEnabled --
which the shared runtime pins to false by constructing under PI_OFFLINE. No
call site passes allowNetwork: true.
The auth tests lose reloadConfig() as an observation seam, so the offline
regression cases now drive removeRuntimeApiKey(), the surviving public mutation
that still forwards the construction-time network flag to refresh().
The reworked assertion ran under the file-level PI_OFFLINE=1 stub, so the
runtime was offline whether or not createOfflineModelRuntime forced it and
the test passed with the fix fully removed. Clear the stub for that case,
and rewrap a docblock line.
Finding 6: serialize createOfflineModelRuntime so overlapping calls cannot
interleave their PI_OFFLINE save/restore pairs and leave the process offline,
and name the process-wide visibility of that window in the docblock.
Finding 7: assert the offline construction through the public refresh seam via
reloadConfig() — the request path that regressed — instead of reading upstream's
private modelNetworkEnabled field.
Finding 8.4/8.5: document the background provider-catalog refresh in
docs/config.md and docs/config.html (cadence, timeout, single retry, offline
opt-out via PI_WEB_OFFLINE / PI_OFFLINE only), and update the changeset to
match the behavior after the earlier fixes.
`dispose()` only cleared timers, so a refresh already in flight kept its
provider fetch alive for the rest of the timeout budget and could delay
daemon shutdown, which is exactly when sessiond disposes the refresher.
A refresher-lifetime AbortController is now combined with the per-run
timeout via `AbortSignal.any`, and `dispose()` aborts it. A
dispose-triggered abort logs as expected shutdown info rather than a
timeout warning or an error, whether the runtime resolves as aborted or
rejects.
`start()` is now idempotent: a second call previously overwrote both
timer handles and leaked the first pair, which kept firing.
Also replaces the `then().catch()` bookkeeping chain in `queueRefresh()`
with an awaited private `runCycle()`, keeping the coalescing, retry, and
dispose semantics unchanged.
Tick the background catalog refresher hourly instead of every four hours:
pi stamps `checkedAt` after a fetch completes, so a tick at exactly its 4h
freshness window always landed a few seconds short and only fetched on
every other tick (~8h effective). Scheduled runs stay unforced, so the
extra ticks are nearly free and pi's gate keeps deciding when to fetch.
Auth-triggered refreshes now pass `force: true` so a re-login of a
provider refreshed within the last four hours actually reaches the
network. A request queued behind an in-flight run keeps the strongest
mode asked for, so a forced request is never downgraded.
Raise the whole-cycle timeout to 60s, since one run covers every
refreshable provider and a background job has no startup budget, and give
a timed-out or errored run exactly one bounded retry. Retries never earn
retries, are superseded by any fresh request, and are cleared by
`dispose()`.
The background model catalog refresher always requested a network refresh,
so sessiond fetched provider catalogs on a schedule even when the operator
set PI_OFFLINE or PI_WEB_OFFLINE. Before the refresher existed, those
settings made every runtime refresh local-only.
Add `offlineModeEnabled()` to the config module and inject the resulting
flag from sessiond's frozen daemon environment, so the refresher schedules
nothing and ignores auth-triggered requests in offline mode. The narrower
PI_SKIP_VERSION_CHECK / PI_WEB_SKIP_VERSION_CHECK keys are deliberately not
included: they only suppress release lookups.
The shared ModelRuntime was constructed with network refreshes enabled, so
reloadConfig()/login()/logout() — called on the model picker, session model
changes, and auth dialogs — performed unbounded provider-catalog fetches.
A single stalled fetch blocked those requests for minutes and, through pi's
coalesced per-provider refresh, dragged session creation along with it.
Construct the runtime with PI_OFFLINE forced so every runtime-driven refresh
stays local, and add ModelCatalogRefresher as the single deliberate network
path: bounded by an abort timeout, serialized through one in-flight run,
scheduled in the background, and triggered after provider auth changes.
Relaxes the provider policy from 'global config only' to 'global sources':
providers registered by agent-dir (global) extensions are learned once at
daemon startup and allowed on the shared runtime; project-extension
registrations are still rejected with a session warning. Global extensions
load identically for every session, so their providers are daemon-consistent
and cannot leak project state (#76).
- Shim now allows allowlisted ids through and also covers Pi 0.81's native
provider path (registerNativeProvider), closing a bypass.
- Startup learning step loads only global extensions against a scratch cwd
and diffs the runtime's registered provider ids.
- Bumps @earendil-works/* dev/peer ranges to >=0.81.1 <0.82; adapts to the
Agent.streamFn -> streamFunction rename.
- Docs, changeset, unit and acceptance tests updated (global-extension allow
path, late re-registration a la pi-tensorx, native provider rule).
Unit tests for the policy shim (swallowed registrations, no-op
unregister, untouched global providers, rejection wording) and
acceptance tests wired as sessiond wires production: load-time
rejections surface as session warnings while extension tools and
commands keep working, late registrations are broadcast to active
sessions' notification inboxes, colliding provider ids across
workspaces cannot affect each other, and a project-level models.json
does not alter the shared runtime.
PI WEB only supports globally configured providers (Pi built-ins,
agent-dir models.json, environment credentials). A daemon-wide shim on
the shared ModelRuntime swallows extension registerProvider calls and
makes unregisterProvider a no-op, so one workspace's extensions can no
longer corrupt the provider set of concurrent sessions (issue #76).
Rejections during a services load surface as session warnings through
the existing diagnostics pipeline; late registrations from session
event handlers broadcast a notification to active sessions. Everything
else extensions register keeps working.
Requires manual restart of pi-web-sessiond.service (daemon wiring changed).
Replace AuthStorage.inMemory / ModelRegistry.create|inMemory across all test
and support code with the pi-ai InMemoryCredentialStore + async
ModelRuntime.create({ credentials }). Add shared test-runtime seams
(createTestModelRuntime, testModelRuntime, seedCredential) in testSupport.ts
and thread modelRuntime into fakeRuntime and every PiSessionService
construction (now a required dependency). Rework the anthropic subscription
warning tests onto a temp auth.json seam read via readStoredCredential, and
the auth-loss warning test onto a live credential store + runtime refresh.
Make getLoginProviderOptions synchronous and fix associated await/lint sites.
npm run verify green (typecheck + lint + knip + 1390 tests).
Pass modelRuntime to createAgentSessionServices instead of authStorage +
modelRegistry; carry ModelRuntime on PiAgentSession; make modelRuntime a
required PiSessionService dependency (sessiond already injects auth.runtime).
Switch anthropicSubscriptionWarning to readStoredCredential, and rederive
model reads (availableModels/setModel/syncCurrentModelAuthWarning) via the
runtime (getAvailableSnapshot/getModel/hasConfiguredAuth). sessiond.ts and
piSessionService.ts now typecheck; only slice-5 test/support files remain.
Reimplement OAuthLoginFlowService against the pi-ai AuthInteraction
({ signal?, prompt(AuthPrompt), notify(AuthEvent) }) contract instead of
the removed OAuthLoginCallbacks shape, and drive login via
runtime.login(providerId, "oauth", interaction). start() now takes a
ModelRuntime instead of authStorage, resolving the authService.ts line-83
error. AuthPrompt text/secret/manual_code/select map onto the existing
web-UI prompt/select flow state; auth_url/device_code map onto the auth
field; info/progress append to progress. Per-prompt AuthPrompt.signal now
cancels just that pending request without ending the flow.
Slice 3 of the issue-62 authStorage migration relay.
Rederive login/logout provider options from runtime.getProviders() +
listCredentials() + getProviderAuthStatus() instead of the removed
authStorage.getOAuthProviders()/list()/get() + getAll()/
getProviderDisplayName() surface (Pi 0.80.8+).
- Replace the AuthProviderModelRegistry structural interface with a
runtime-shaped AuthProviderRuntime (getProviders/listCredentials/
getProviderAuthStatus); a real ModelRuntime satisfies it.
- Make getLoginProviderOptions/getLogoutProviderOptions async to match
the await call sites already in authService.ts.
- OAuth-capable providers = auth.oauth present; api-key providers =
auth.apiKey present, preserving OAUTH_ONLY_PROVIDERS /
isApiKeyLoginProvider logic. Display names from Provider.name.
- Update the test double to the new runtime shape.
Slice 2 of the authStorage migration relay. tsc: 31 -> 28 errors
(remaining are cross-slice: slices 3/4/5).
Move AuthService off the removed AuthStorage / ModelRegistry.create surface
onto the async ModelRuntime API:
- AuthService.create({ agentDir | runtime }) async factory wrapping
ModelRuntime.create({ authPath, modelsPath }); createModelRuntimeForAgentDir
replaces createModelRegistryForAgentDir.
- saveApiKey -> runtime.login(providerId, "api_key", nonInteractive) so the
key is persisted through the runtime credential store.
- logoutProvider -> runtime.logout; refreshAuthState -> await runtime.refresh().
- startOAuthLogin now passes the runtime into OAuthLoginFlowService.start.
- authProviders/requireOAuthLoginProvider became async around getLogin/Logout
provider options.
- sessiond.ts: async createRuntime, AuthService.create, pass modelRuntime to
PiSessionService; sessionDaemonStartup awaits createRuntime.
Cross-slice: authProviderOptions (2), oauthLoginFlowService (3), and
piSessionService (4) still expose the old ModelRegistry shape, so the tree does
not fully typecheck yet. Session-daemon path changed -> manual sessiond restart
needed once the migration lands.
Show a pinned banner at the top of the session view with resource and
runtime diagnostics (skills, prompts, themes, extension load errors) plus
the Anthropic subscription-auth billing notice, recomputed live from the
current runtime so they stay accurate across browser reloads.
Warnings carry an optional dismiss capability; the Anthropic notice is
dismissable and durably suppressed through pi's own anthropicExtraUsage
warning setting. Also fixes the testing-guide skill frontmatter so it
loads.
Seed the in-flight partial assistant message (text, thinking, and
in-progress tool calls) when opening or reconnecting to a session that is
mid-stream, then continue streaming live deltas on top of it. Replaces the
blocking "Catching up..." placeholder and the end-of-turn transcript reload.
Server stamps every per-session UI event with a monotonic seq at the
SessionEventHub publish choke point and exposes
GET /sessions/:sessionId/stream-snapshot returning { seq, partial }. The
client fetches the snapshot on join, seeds the normalized partial into the
in-memory transcript (never the history cache), and applies buffered/live
events using the seq watermark for exactly-once delivery.
The snapshot is a progressive enhancement: a 404 from an older remote
pi-web or a not-yet-restarted session daemon falls back to an empty seed
(seq 0, drops nothing), so sessions still open and stream normally. The
stream-snapshot route is registered in the federation allowlist for
remote-machine proxying.
