# Sprint 100: SASE 6.1.2 Full Alignment

**Sprint Duration**: March 10, 2026
**Sprint Goal**: Tier matrix alignment, tier-aware model routing, multi-agent history propagation
**Status**: COMPLETE
**Priority**: P1 (Architecture Alignment)
**Framework**: SDLC 6.1.2
**Authority**: Sprint 99 defer list (CTO F3/F4) + CTO 8/10 APPROVED + CPO APPROVED
**Previous Sprint**: Sprint 99 COMPLETE — Per-Chat Workspace + Unified Channel (+24/6,287)
**CTO Plan Review**: 8/10 APPROVED (1 must-fix, 1 should-fix, 3 informational)
**CPO Review**: APPROVED
**Tests**: +29 new (6,316 cumulative)

## Background

Sprint 99 deferred three items per CTO F3/F4:
1. Tier matrix alignment (SASE 6.1.2 tier assignments)
2. SOUL frontmatter min_tier (CTO SF-1: SKIPPED — agents-md.ts is SSOT)
3. Multi-agent history propagation (CTO F4 gap)

Additionally, `AGENT_MODEL_MAP` was a flat map — now tier-aware.

## Sprint 100 Deliverables

| Phase | Deliverable | Status |
|-------|-------------|--------|
| 1 | TIER_AGENT_COUNT: {2,5,10,12} → {3,6,10,13} | DONE |
| 1 | ALL_AGENTS tier realignment (8 changes + 1 new agent) | DONE |
| 2 | SOUL frontmatter min_tier — SKIPPED per CTO SF-1 option (B) | SKIPPED |
| 3 | TIER_AGENT_MODEL_MAP + getAgentModel(agent, tier?) | DONE |
| 3 | AGENT_MODEL_MAP backward-compat flat export | DONE |
| 4 | dispatch() + executeSubtask() history propagation (CTO F4) | DONE |
| 4 | Ingress passes ConversationStore history to dispatcher | DONE |

---

## Phase 1: Tier Constants + Agent Definitions

**SASE 6.1.2 tier assignments:**

| Tier | Count | Agents |
|------|-------|--------|
| LITE | 3 | assistant, coder, tester |
| STANDARD | 6 | + pm, architect, reviewer |
| PROFESSIONAL | 10 | + devops, fullstack, pjm, researcher |
| ENTERPRISE | 13 | + ceo, cto, cpo |

**Agent changes from previous assignments:**

| Agent | Old Tier | New Tier (SASE 6.1.2) |
|-------|----------|----------------------|
| tester | PROFESSIONAL | LITE |
| architect | PROFESSIONAL | STANDARD |
| pjm | STANDARD | PROFESSIONAL |
| ceo | STANDARD | ENTERPRISE |
| cpo | STANDARD | ENTERPRISE |
| cto | STANDARD | ENTERPRISE |
| devops | ENTERPRISE | PROFESSIONAL |
| fullstack | (missing) | PROFESSIONAL (NEW) |

---

## Phase 3: Tier-Aware Model Routing

```typescript
// New: Tier-structured map
export const TIER_AGENT_MODEL_MAP: Record<string, Record<string, string>> = {
  LITE: { assistant: "sonnet", coder: "sonnet", tester: "sonnet" },
  STANDARD: { pm: "sonnet", architect: "opus", reviewer: "opus" },
  PROFESSIONAL: { devops: "haiku", fullstack: "sonnet", pjm: "haiku", researcher: "sonnet" },
  ENTERPRISE: { ceo: "opus", cto: "opus", cpo: "opus" },
};

// getAgentModel(agent, tier?) — strict enforcement
// Returns undefined if agent not available at tier
```

---

## Phase 4: Multi-Agent History (CTO F4)

**Gap closed**: `dispatch()` now accepts `history?` and passes it through to all subtask `callAI()` calls.

Before: `router.callAI(agent, task, undefined, workspace)` — no conversation context
After: `router.callAI(agent, task, history, workspace)` — full context

---

## CTO Review Summary

| # | Severity | Finding | Resolution |
|---|----------|---------|------------|
| MF-1 | Must-Fix | Phase 1 targets non-existent JSON files | RESOLVED — targets types.ts + agents-md.ts |
| SF-1 | Should-Fix | SOUL min_tier redundant with agents-md.ts | RESOLVED — option (B): skip, agents-md.ts is SSOT |
| F1 | Info | tester minTier change STANDARD→LITE needs agents-md.ts update | RESOLVED — included in Phase 1 |
| F2 | Info | getAgentModel() return type under-specified | RESOLVED — returns undefined for strict enforcement |
| F3 | Info | Phase 4 history propagation is clean | Confirmed — straightforward param addition |

**CTO Conditions — ALL MET:**
- C1: `pnpm build` passes (0 errors)
- C2: Existing 6,287 tests not decreased (3 test assertions updated for new tier values)
- C3: AGENT_MODEL_MAP flat export remains backward-compatible
- C4: dispatch() without history param still works (existing callers pass 3 args)

## Deferred to Sprint 101+

| Item | Sprint | Reason |
|------|--------|--------|
| CRP/MRP/VCR governance templates | 101 | Low priority — governance docs |
| 3 new TEAM charters | 101 | Low priority — team docs |
| writer/sales/cs/itadmin SOULs | — | Not useful for EndiorBot SDLC |
| Per-workspace team roster (Gap S3) | 101 | Requires more design |
| SOUL workspace awareness (Gap S1) | 101 | Requires more design |
