Mission Scratchpad — MVP
Append-only log. NEVER delete entries. NEVER overwrite sections.
This is the orchestrator's working memory across sessions.

Planning Decisions
2026-03-13 — Milestone and task breakdown
- PRD defines 8 phases (Phase 0–7), mapped 1:1 to Gitea milestones
- 59 issues created on git.mosaicstack.dev/mosaic/mosaic-stack (#1–#59)
- Each phase has a verification task as the final issue
- Task IDs use P{phase}-{seq} format (P0-001 through P7-008)
- Repo created as
mosaic/mosaic-stack (private) on Gitea
- Milestones: ms-157 (Phase 0) through ms-164 (Phase 7)
- Total: 59 tasks across 8 milestones

Foundation |
P0-002, P0-005, P0-006 |
Foundation layer merged (PR #65). Docker Compose (PG+pgvector, Valkey, OTEL Collector, Jaeger), OTEL auto-instrumentation in gateway, @mosaic/types with DTOs + Socket.IO typed event maps. |

Foundation |
(fix) |
Fixed Jaeger tag (2→2.6.0), remapped PG/Valkey ports (5433/6380) to avoid host conflicts. PR #66 merged to main. |
Verification evidence:
- All 4 containers healthy (PG, Valkey, OTEL Collector, Jaeger)
- OTEL pipeline proven:
mosaic-gateway service visible in Jaeger UI
- Gateway traces flow through Collector → Jaeger

Corrections
2026-03-13 — Vertical slice reorder (Jason directed)
Original plan: Linear Phase 0 → 1 → 2 → ... execution.
Correction: Vertical slice first. Scaffold monorepo, then build the Pi TUI → Gateway → Discord communication spine end-to-end before backfilling auth, brain, memory, CRUD, etc.
Why: Validate the architecture's core message flow before investing in horizontal layers. If the communication channels don't work, nothing else matters.
Revised execution sequence:
| Step |
Tasks (cross-phase) |
What it proves |
| 1 |
P0-001: Scaffold monorepo |
Build system works |
| 2 |
P0-005: Docker Compose (PG + Valkey) |
Infrastructure runs |
| 3 |
P0-002: @mosaic/types (minimal — gateway, agent, chat types) |
Shared contracts |
| 4 |
P1-001: Gateway scaffold (minimal NestJS + Fastify) |
API surface boots |
| 5 |
P1-007: WebSocket server (chat streaming) |
Real-time channel works |
| 6 |
P1-008: Basic agent dispatch (single provider) |
LLM responds |
| 7 |
P2-001: @mosaic/agent — Pi SDK integration (minimal) |
Pi sessions work |
| 8 |
P6-005: Pi TUI integration (mosaic tui → gateway) |
TUI ↔ Gateway proven |
| 9 |
P5-001: Plugin host (channel plugin interface) |
Plugin arch works |
| 10 |
P5-002: Discord plugin (bot + channel) |
Discord ↔ Gateway proven |
| — |
Then backfill: auth, brain, db, queue, OTEL, CI, web dashboard, etc. |
