Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The current implementation can invoke overridden string conversion on rejected values and can return the wrong exception for oversized negative integers, which may expose caller-controlled behavior or break validation handling. The PR is not merge-ready until safe representations are limited to exact built-in numeric types and bounded before opt-in. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 38-43: Update the safe_value construction before ValidationError
so only exact built-in bool, int, and float values are converted, never
subclasses, and only strings no longer than 128 characters are passed through.
Use None for all other values, including oversized negative integers, while
preserving the existing ValidationError path.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head7aad1778c6e20d20402052688d99aec2d1a77cd5. -

Exact-head verification after non-force serialization behind current #323: the effective production delta is confined to pg_llm_batch/exceptions.py; current #323 driver/orchestrator implementation remains parent authority. The real 45-test RED from the first #233 reconciliation was repaired by making stale assertions match the fail-closed rejected-value policy and by preserving hostile-renderer/oversized-integer regression cases. Exact b8fd11a93cbaea851b7ea8166f9a28d46b92fe33 now has CI 34756635313 SUCCESS and Release Acceptance 34756635333 SUCCESS; the coverage/package lane reports public docstrings 100%, production statement/branch coverage 100.00% (4730 statements / 1350 branches, zero misses/partials), and 1688 passed / 5 deselected. The five Python 3.14 warnings are not accepted as clean: the four schema-finalizer warnings remain owned by #250/#251 and the compose/runpy warning by #252, whose canonical exact heads already carry the causal fixes. No APPROVE is submitted here; parent integration, warning-owner integration, fresh central gates, and qualifying independent approval still remain.

ValidationErrorconfidentiality repair. Arbitrary rejected caller values do not acquire diagnostic-disclosure authority merely because validation failed: generic construction redactsdetails["value"], does not render or retain the rejected object, and permits disclosure only through the boundedsafe_valuecontract.safe_valuemust be an exact built-instr, printable ASCII, 1–128 characters; subclasses and invalid evidence fail closed.This lane does not restore the historical behavior that stringified rejected numeric values.

__str__/__repr__, oversized integers, bool/numeric subclasses, batch lookup keys, endpoint values, tenant scopes, lifecycle seam values, byte-size evidence, and runtime token-limit failures remain covered by the redaction contract.Exact current topology — 2026-09-20

Ownership and descendants
The effective production delta remains confined to
pg_llm_batch/exceptions.py; #323 retains PostgreSQL-driver/checkpoint authority. Warning repair remains #250/#251/#252 authority and is neither copied nor suppressed here.Direct child #344 is ordinary/non-force reconciled onto this exact parent as
91b86f11ac0bf053e43ecfcbb2529d752e480e2f. Its relative diff remains onlypg_llm_batch/exceptions.py,tests/test_exceptions.py, andtests/test_token_counter.py; exact-head CI35441832939and Release Acceptance35441832880have both succeeded independently.Integration boundary
Root #233 remains the protected integration prerequisite. Normal order is central prerequisite convergence → #233 normal protected integration → #323 reconcile/integrate with fresh exact evidence → this privacy child reconcile/evidence → #344 reconcile/evidence → normal child integration → root documentation convergence → protected-head immutable release evidence.
