Welcome — you are **flower-backend**, the backend agent for the flower project, in a fresh ISOLATED git worktree. Call whoami() first (proc 977 / project 53). ENVIRONMENT: - You're in `~/Documents/code/worktrees/flower/backend` on branch `backend`.

key decisions

• Catch GuzzleHttp\Exception\ConnectException in addition to Laravel's ConnectionException so pool timeouts trigger adaptive subdivision.
• Added reduce-timeout fallback to produce a reduced response from successful map summaries rather than throwing after all map work is done.
• Separate chunked request timeout from single-call timeout to avoid 20-minute stalls.

key decisions

• Guard at service boundary before any Process::path call, not just at command level.
• Use Log::warning for structured logging of skipped paths and runtime failures.
• Regression test uses alphabetical ordering to ensure batch continues after a skipped path.

key decisions

• Use a new DaemonCompactionState enum with values none, requested, in_progress, done.
• Add compaction_state column via a new migration rather than altering the existing one.
• Derive liveness from heartbeat cadence (last_checkin_at vs config thresholds) rather than relying solely on persisted status.
• Use config key flower.daemons (plural) for compaction thresholds while preserving legacy flower.daemon.stale_after_minutes as an optional override.
• Two new MCP tools (daemon_request_compaction, daemon_compaction_done) for state transitions, requiring actor_ref.

key decisions

• Retry the entire transaction rather than individual queries to maintain atomicity.
• Use delete-then-insert for session_events to ensure idempotent re-persist.
• Sort events by ordinal before batched insert to guarantee deterministic ordering.
• Reuse the same retry helper pattern for future batched delete operations.

key decisions

• Abandon retention work per user instruction; do not delete session rows.

open questions

• Whether to add a session_events_pruned_at column now or defer.
• Exact keep_days_after_indexed default value (user suggested 30).

key decisions

• Purger only selects indexes matching flower_test_* prefix.
• Command defaults to dry-run; --force required for actual deletion.
• Base TestCase tracks created test indexes and drops them in tearDown().
• Existing manual tearDownMeiliIndex() path kept for backward compatibility.

key decisions

• Harness inference reads Solo's actual command/agent_state.tool_type fields rather than relying solely on process name heuristic.
• Use harness_match_rank as a secondary sort key after delta_seconds and before solo_process_id to prefer harness-matched candidates.
• Add preferHarnessMatchedCandidates() helper to filter and reorder candidates so null-harness candidates lose to same-cwd harness-matched candidates.

key decisions

• Batched the linked-session activity query instead of bumping the query budget.
• Used a preload map on DaemonRosterService instance to cache session activity per request.
• Added a regression test for linked session liveness in the UI roster path.

next steps

• Create branch flower/dispatch-completion-mcp from master
• Implement brief_dispatch_complete and brief_dispatch_cancel MCP tools in app/Mcp/Tools/
• Register tools in FlowerServer.php
• Update AgentConventions::workingAgentBlock to instruct workers to call brief_dispatch_complete
• Add tests for rollup transitions (dispatched→in_progress/complete on complete, unwedge on cancel)
• Run php artisan test and pint to keep green
• Commit with Brief: #24 trailer and brief_append on 24
• Stop for review/merge

key decisions

• Branch from latest local master (85ecacf) rather than an older ref, ensuring the branch includes recent fixes from Brief #23 and other master commits.
