Why this matters

In ods/extensions/services/dashboard-api/pixel_chat_results.py, chunks(self, key, after=-1) passes after directly to the SQLite query sequence > ?. When string arguments (e.g. from query parameters) or negative numbers below -1 are passed, SQLite comparison semantics can cause unexpected chunk exclusion or type coercion errors.

This surgical fix validates type(after) is int and after >= -1 in chunks, raising TypeError("after must be an integer >= -1").

Validation

• Baseline reproduction: verified that store.chunks(key, after="0") passed through without type checking on baseline.
• Post-fix behavior: properly raises TypeError("after must be an integer >= -1").
• Telemetry: pixel-chat suite: 1 passed. New-test syntax and diff checks pass; new regression wired into Linux CI.

Overlap check

Inspected open/closed PRs. PR #5808 checked owner_namespace; zero overlap with chunk query sequence paging bounds.

Risk / AI disclosure

AI-assisted investigation, patch, and regression tests. Enforces paging parameter validation on chunk retrieval. Independent review remains a gate.

Follow-up integration evidence

Composed locally with public-beta at 6a408cc85 without conflicts. CI and unit checks pass.
