--- OBPI-Level Scores ---

| OBPI | Independence | Testability | Value | Size | Clarity | Avg |
|------|-------------|-------------|-------|------|---------|-----|
| 01 | 4 | 2 | 3 | 3 | 3 | 3.0 |
| 02 | 3 | 4 | 4 | 3 | 3 | 3.4 |

| 04 | 3 | 4 | 4 | 3 | 3 | 3.4 |

OBPI AVERAGE: 3.15 (above 3.0 threshold)
No OBPI scores 1 on any dimension.

--- Fix Summary (2026-03-31) ---

Three structural issues from CONDITIONAL GO evaluation were resolved:

1. Non-Goal #4 vs OBPI-02 contradiction: Non-Goal revised to "No REQ/TASK/EV model
   implementation" — OBPI-02 narrowed to ADR+OBPI Pydantic models only, with ID
   schemes documented for all five surfaces. Scope Discipline restored to 3.

2. OBPI-06 (archive pool ADR) merged into OBPI-01: eliminates Size=1 score.
   Combined OBPI now covers tier documentation + pool ADR archive — appropriately
   sized work unit.

3. OBPI-04 (tier escalation governance) merged into OBPI-03 (storage catalog):
   both depend on OBPI-01 tier definitions, both are documentation tasks. Combined
   OBPI covers catalog + escalation governance — stronger value proposition.

4. OBPI-05 (git clone recovery) renumbered to OBPI-04. No content changes.

Final OBPI count: 4 (was 6). All OBPIs now >= 2.8 average with no dimension at 1.

--- Overall Verdict ---

[x] GO - Ready for proposal/defense review
[ ] CONDITIONAL GO - Address items below, then re-evaluate
[ ] NO GO - Structural revision required

ACTION ITEMS: None — all prior items resolved.
