Ijfw Spec Phase

IJFW Spec-Phase -- lock WHAT before HOW

You are the orchestrator-facing trigger that produces .planning/<milestone>/<phase>/SPEC.md for the active phase. SPEC.md captures falsifiable acceptance criteria, explicit in-scope / out-of-scope boundaries, and dependencies -- BEFORE plan-phase touches HOW to implement.

Domain-agnostic. Same flow for: software slice ("user auth"), book chapter ("Ch4 scope, POV lock, must-cover beats"), campaign slice ("launch week 1 channel mix"), research milestone ("literature review boundaries").

When to fire

1. User explicitly asks: "spec this", "scope this", "lock requirements".
2. plan-phase / execute-phase is requested but no SPEC.md exists for the active slice under .planning/<milestone>/<phase>/.
3. ijfw-workflow Deep path enters the Plan gate with unclear requirements.

Process

1. Locate the active phase

MILESTONE=$(cat .ijfw/state/active-milestone 2>/dev/null \
  || ls -1 .planning/ | grep -E '^[0-9]' | tail -1)
PHASE=$(cat .ijfw/state/active-phase 2>/dev/null || echo "$1")
PHASE_DIR=".planning/${MILESTONE}/${PHASE}"
mkdir -p "$PHASE_DIR"

If $PHASE is unset and not supplied as argument, ASK the user which phase to spec. Never guess.

2. Load context

Read in order, skipping any that don't exist:

1. .ijfw/memory/brief.md -- the original ask
2. .planning/ROADMAP.md -- where this phase sits
3. .planning/<milestone>/ROADMAP.md -- milestone-scoped roadmap
4. Any prior SPEC.md / CONTEXT.md from earlier phases in this milestone
5. .planning/PROJECT.md -- non-negotiables

Extract: phase goal, declared boundaries, prior decisions that flow forward.

3. Identify ambiguities (gray areas)

For the phase, list:

• What's clear -- requirements with one obvious interpretation.
• What's gray -- decisions that could go multiple ways and would change the result. Each gray area is a single sentence.
• What's decided -- already locked in a prior phase's CONTEXT.md or SPEC.md.

If gray-area count is zero: skip Step 4 and write SPEC.md directly using captured-as-clear requirements.

4. Dispatch ijfw-discuss-phase (if gray areas exist)

Task: ijfw-discuss-phase
Args:
  milestone: $MILESTONE
  phase: $PHASE
  gray_areas: [list of one-line ambiguities]
  prior_decisions_path: .planning/<milestone>/*/CONTEXT.md

The agent will interrogate the user adaptively (AMBIGUITY SCORING -- top 3-5 gray areas by impact x uncertainty), capture decisions to $PHASE_DIR/CONTEXT.md, and return when the user is satisfied OR escalates.

Wait for the agent. Do NOT proceed to SPEC.md until CONTEXT.md exists.

5. Write SPEC.md

After CONTEXT.md is locked (or skipped if no gray areas), write to $PHASE_DIR/SPEC.md with these sections:

# SPEC -- <milestone> / <phase>
**Locked:** <ISO date>  **Status:** Ready for plan-phase

## Goal
<One-sentence outcome -- what the user can do / see / read / receive
 when this slice is shipped.>

## Acceptance Criteria
Each MUST be falsifiable (binary pass/fail; no "should" / "nice").
1. <Criterion>
2. <Criterion>

## In Scope
- <Capability / artifact / chapter section>

## Out of Scope (Deferred)
- <Mentioned but pushed to a later slice>

## Dependencies
- **Inputs:**   <Required from prior slices / external>
- **Outputs:**  <Handed to the next slice>
- **External:** <APIs, libraries, vendors, sources>

## Domain Notes
<Software: data shapes, contracts. Book: POV, tone, chapter beats.
 Campaign: audience, channel mix, KPI target.>

## Canonical References
- CONTEXT.md (this slice's decisions)
- <Any ADRs / specs / prior SPEC.md cited>

6. Commit + report

git add "$PHASE_DIR/SPEC.md"
git commit -m "spec($PHASE): lock requirements before plan-phase"

Report to orchestrator:

SPEC.md ready: <path>
Acceptance criteria: <N>
Gray areas resolved: <M>
Deferred items: <K>
Next: /ijfw-plan-phase $PHASE

Anti-patterns (do not do)

• Do NOT write SPEC.md without resolving gray areas first (defeats the point).
• Do NOT include implementation details (those belong in plan-phase output).
• Do NOT silently re-decide things already locked in prior CONTEXT.md files.
• Do NOT exceed phase boundary from ROADMAP.md -- scope creep gets deferred, not absorbed.

Success criteria

• SPEC.md exists at .planning/<milestone>/<phase>/SPEC.md.
• Every acceptance criterion is binary-falsifiable.
• In-scope / out-of-scope are explicit (no ambiguity at boundary).
• Dependencies cite concrete inputs and outputs.
• CONTEXT.md exists alongside if any gray areas were interrogated.
• Commit landed; orchestrator can hand off to plan-phase.
