Author: agent

Summary (one sentence)¶

Adds PH-DB to the lic master plan phase map and appendix cross-linking roadmap lidb proposals, including PH-8d-v2 → PH-DB-4 dependency.

Agent continuation (required)¶

1. Read: docs/superpowers/plans/ph-db-lidb-platform.md; roadmap vision-and-roadmap § PH-DB
2. Run: N/A (docs-only)
3. Then: human creates li-langverse/lidb for PH-DB-1; implement engine in lidb repo after merge
4. Blocked on: human repo creation for PH-DB-1; PH-8d-v2 until PH-DB-4 exit gate

Changed (specific)¶

Not changed (scope fence)¶

• lidb runtime — no engine, WAL, or SQL implementation in lic
• Roadmap repo — canonical PH table already in vision-and-roadmap.md; this PR is lic cross-link only
• lip / lit / compiler — no registry v2 API or CI gate changes
• PH-8d v1 — local registry publish unchanged

Breaking changes¶

None — documentation only.

Security¶

N/A — no code paths; future PH-DB-2 security harness referenced in roadmap ADR only.

Performance¶

N/A — bench evidence path is tier_db_registry in benchmarks repo (not run here).

Downstream¶
