Why this matters

In ods/bin/pixel_provider/runtime_gateway.py, the validate_request routine admits the optional seed parameter without strict type validation. Because Python booleans are instances of int and unconstrained JSON inputs may supply floating-point or string representations, requests containing seed: True, seed: 1.0, or seed: "42" bypass validation, resulting in subtle RNG misconfiguration or downstream engine crashes.

This change surgically enforces type(payload['seed']) is int in validate_request, rejecting non-integer and boolean seeds with invalid-inference-request. Valid integer seeds across arbitrary signed 32/64-bit boundaries remain fully supported.

Validation

• Baseline reproduction: Payloads specifying seed: True, seed: False, seed: 1.0, or seed: "42" were accepted by validate_request.
• Post-fix behavior: Requests with boolean or non-integer seed types raise RuntimeErrorCode('invalid-inference-request'). Standard integer seeds pass cleanly.
• Telemetry: Pixel gateway suites: 2 passed. New-test Ruff, ShellCheck, and diff checks pass; new regressions wired into Linux CI.

Overlap check

Recent PRs #6330 (temperature bounds in runtime gateway), #6329 (top_p bounds in runtime gateway), and #6328 (rollback snapshot permissions in ods-update.sh) touch independent parameters and subsystems. This PR focuses exclusively on the seed parameter type guard in ods/bin/pixel_provider/runtime_gateway.py without conflict.

Risk / AI disclosure

AI-assisted investigation, implementation and CLI regressions. This strengthens an API validation check, not runtime admission. Independent human review and platform/runtime qualification remain gates. No running configuration, deployment or upstream merge changed.

Follow-up integration evidence

Composed with #6330 at 0dde07e without conflicts. Production and test diffs passed together; gateway and runtime checks remain intact.
Backlog composition was local-only (production/test diffs, excluding workflow/Makefile wiring); it is not an upstream merge or independent human approval. Declared live-review gates remain open.
