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.
Sessiond caches the in-memory SessionManager and never re-reads the
session file. When the same session is also being edited by another
process (e.g. the pi CLI), new entries on disk are invisible to the
web UI \u2014 the tail of the conversation gets cut.
Add a manual Reload action in the session three-dot menu:
- Server: PiSessionService.reload(sessionId) closes the active
session and re-opens it from disk, then publishes a fresh status.
Exposed as POST /api/.../sessions/:sessionId/reload.
- Client: api.reloadSession, SessionController.reloadSession which
discards the cached transcript and re-runs selectSession so the
history page is re-fetched.
- ChatTranscriptStore gains discard(sessionId) and the history
cache adapter gains optional remove(sessionId).
- SessionList shows a Reload entry for non-archived, non-cached
sessions; plumbed through AppNavigationPanel and PiWebApp.
Note: pi-web-sessiond.service must be restarted manually after this
change since the session daemon code path is affected.
Depend on @earendil-works/pi-agent-core so the ThinkingLevel union has a single source of truth (re-exported via shared/thinkingLevels). Wire/data fields use string and the parser is lenient, so an unknown level from a newer pi runtime is still listed, selectable, and rendered gracefully instead of throwing. The composer gauge now derives its bar count from the levels available for the current model and fills by rank. Adds compile-time drift guards (satisfies + Exclude check) and unit tests so a changed pi level set fails fast in development.
Support pasting (Ctrl/Cmd+V), drag-and-drop, and an Attach button to add
PNG/JPEG/GIF/WebP images to a message, with thumbnail previews and
multi-image support.
Attachments are delivered to the session using pi's native ImageContent
format and are run through pi's own resizeImage so they match pi's inline
image limits exactly. Image content now renders inline in the transcript.
A per-message delivery toggle also lets users save attachments into the
workspace `.pi-web/paste` folder and reference them so the agent reads
them with its own tools.
The accepted HTTP upload size is configurable via PI_WEB_MAX_UPLOAD_BYTES
or the maxUploadBytes config value (default 64 MB).
Closes#13
Sessions outside the server's launch directory were invisible and returned
404 on open, leaving the model picker empty. List without the SDK's
process-cwd filter and normalize working directories at the API boundary and
when reading stored session data, tolerating separator/normalization
differences (including Windows backslash vs forward slash). Requires Pi
coding agent SDK 0.78.0 or newer.
