Integrate the pending-ask store into the session service so an open ask is
visible, observable, and closable.
- `statusFromSession` projects `pendingAsk`, so a browser rehydrates an open
ask from `GET /sessions/:sessionId/status` after reload or a web/API restart.
- `openAsk` publishes `ask.opened`, and publishes `ask.closed` first when the
new ask supersedes an unanswered one.
- `submitAsk` / `cancelAsk` close the ask and hand the outcome to the model as
a `pi-web.ask.answers` follow-up custom message (`triggerTurn`,
`deliverAs: "followUp"`), the same delivery subsession notices use. A stale
ask id is reported, not thrown: losing the race against a supersede or
another browser is ordinary. Cancel still reports every question as
unanswered so the model is not left waiting for a promised message.
- The open ask is forgotten when its runtime closes; nothing is left to
receive the answers.
- `POST /sessions/:sessionId/ask/{submit,cancel}` behind the existing
`/api/sessions/*` daemon proxy, allowlisted for machine federation.
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.
