Repair SQLite WAL Checkpoint Read Lock Starvation

Repair SQLite WAL Checkpoint Read Lock Starvation — SYNTHETIC EVIDENCE-LIMITED REVIEW

Case received

A kiosk application accumulates WAL pages while a reporting process holds a stale snapshot.

Evidence register

• S1: SQLite checkpoint logs and connection lifetimes — PARTIAL / UNVERIFIED.
• S2: authorized baseline or procedure — NOT PROVIDED; REQUIRED TO VERIFY.
• S3: timestamped event and change context — NOT PROVIDED; REQUIRED TO VERIFY.
• S4: responsible reviewer / approval record — NOT PROVIDED; REQUIRED TO VERIFY.

Four checks

1. Normalize identifiers and timestamps in SQLite checkpoint logs and connection lifetimes; preserve original document revisions. — PENDING CORROBORATION.
2. Locate long-lived reader prevents WAL truncation and link every finding to exact source rows or event IDs. — PENDING CORROBORATION.
3. Test whether the stated scenario is supported by the baseline, sequence constraints and independent counter-evidence. — PENDING CORROBORATION.
4. Define an owner-reviewed, reversible verification sequence for reversible checkpoint and reader-lifetime plan before any field or production change. — PENDING CORROBORATION.

Deliverables

• SQLite checkpoint logs and connection lifetimes traceability crosswalk: DRAFT / INCOMPLETE until inputs are validated.
• long-lived reader prevents WAL truncation exception ledger: DRAFT / INCOMPLETE until inputs are validated.
• reversible checkpoint and reader-lifetime plan approval and validation plan: DRAFT / INCOMPLETE until inputs are validated.

Decision gate

INCOMPLETE — HUMAN REVIEW REQUIRED. Source chronology, approvals, scope and independent evidence have not been verified. No execution or live certification claimed.
