**Phase:** 144-l1-assumption-ledger-and-reading-depth-surface
**Areas discussed:** intake continuity, operator visibility, bounded verification

---

## Intake Continuity

| Option | Description | Selected |
|--------|-------------|----------|
| extend existing `l1_source_intake` | preserves `v1.64` closure and avoids duplicated truth surfaces | ✓ |
| create a second assumption/depth artifact family | would fragment the `L1` operator path | |

## Reading-Depth Honesty

| Option | Description | Selected |
|--------|-------------|----------|
| keep skim/conflict limitations explicit | matches the real open gap in `999.27` | ✓ |
| flatten all source signals into one stronger summary | would overclaim intake certainty | |

## Verification Shape

| Option | Description | Selected |
|--------|-------------|----------|
| isolated acceptance plus targeted regression slice | enough to close this bounded intake-honesty lane | ✓ |
| reopen broad `L1` full-suite redesign before closure | too wide for the immediate gap | |
