jason.woltjeandClaude Opus 4.8	5c643cd54e	fix(fleet): bake MOSAIC_AGENT_NAME into the agent pane so native HB fires ... Live-validation (Lead, w-jarvis) found the native heartbeat was INERT in production: the Pi extension gates on MOSAIC_AGENT_NAME, but tmux panes inherit the tmux SERVER environment (not this script's env, nor the systemd unit's), so the name was empty in-pane for BOTH ad-hoc and systemd agents. Result: no native .hb, no model self-report — only the sidecar fallback ran. Fix: %q-quote the agent name and export it into the pane command alongside PATH, so the extension sees it -> nativeHbEnabled() -> writes <name>.hb with model + busy/ok turn state. Re-validated live via the launcher (isolated socket, real pi on glm-5.2): - pane env now carries MOSAIC_AGENT_NAME - <name>.hb written with status=ok + model=glm-5.2 + .hb.native marker - status flips ok -> busy on a real turn -> ok on turn end - sidecar defers to the fresh native marker Co-Authored-By: Claude Opus 4.8 <[email protected]> Claude-Session: https://claude.ai/code/session_01EsgTQzV5YUGk1JtCLP4B83	2026-06-21 20:41:42 -05:00
jason.woltjeandClaude Opus 4.8	b26bbb02e9	feat(pi): register model-callable mosaic_mission_status tool ... Adds a first-class registerTool (R14 'proper tool usage') so the Pi agent can load its active Mosaic mission, milestone progress, task counts, and latest scratchpad as a tool call before planning — instead of shelling out or guessing. Reuses detectMission/buildMissionSummary; returns AgentToolResult text + structured details. promptGuidelines names the tool explicitly per the pi extension authoring contract. Tool shape verified against @earendil-works/[email protected].9 ToolDefinition (name/label/description/promptSnippet/promptGuidelines/ parameters + execute(toolCallId,params,signal,onUpdate,ctx)).

jason.woltjeandClaude Opus 4.8	bda38bddc1	feat(fleet): surface self-reported model in fleet ps ... parseHeartbeat now reads an optional model= line from the heartbeat file (written by native runtime heartbeats) into HeartbeatInfo.model, and fleet ps surfaces it as a MODEL column (table) and in --json (via rows[].heartbeat.model). Legacy/sidecar heartbeats omit the line and report model=null, so the column shows '-'. Closes the model self-report gap end-to-end with the native Pi heartbeat writer (F3-m2): the runtime self-reports its active model and the fleet operator can see it in ps.

jason.woltjeandClaude Opus 4.8	56e5c35678	wip(fleet): F3-m2 native Pi heartbeat + sidecar reconciliation ... WIP — not for merge yet. Implements the core of the custom Pi harness (R14/R15): - runtime/pi/mosaic-extension.ts: native heartbeat — writes the same .hb contract (ts/pid/status[/model]) on a MOSAIC_HEARTBEAT_INTERVAL timer; turn_start/turn_end flip status busy/ok; model self-report via ctx.model; touches a .hb.native precedence marker. Also FIXES a latent bug: session_end -> session_shutdown (the old handler never fired) + corrects the import scope to @earendil-works/pi-coding-agent. - start-agent-session.sh: sidecar DEFERS when the .hb.native marker is fresh (< 2x interval), else writes the fallback — native precedence, sidecar fallback, same contract so fleet ps is agnostic (per Lead's design). Generated script validated (bash -n) + deferral/fallback behavior tested. REMAINING before PR: surface model in `fleet ps` (parseHeartbeat + row); vitest for the native-HB writer; "proper tool usage" (registerTool) piece; rebase onto #599's %q sidecar (overlap on the printf line).
