Fix Windows CI Unicode crash; enumerate ontological issues in oe_ifm

[Copilot]

All 3 Windows CI jobs (Python 3.10–3.12) crashed with UnicodeEncodeError before any determinism test ran — ✓/✗ characters in print() calls are unencodable in the default Windows cp1252 codec.

Changes

CI fix — .github/workflows/pr26-cross-platform.yml

Added PYTHONIOENCODING: utf-8 to the "Run determinism test" step so Python stdout uses UTF-8 on all platforms:

env:
  PYTHONHASHSEED: 0
  PYTHONIOENCODING: utf-8   # ← added; prevents cp1252 UnicodeEncodeError on Windows

Ontological issues enumeration — enumerate_ontological_issues.py

New script that scans the oe_ifm module against the existing OE failure ontology (ontology/failure_ontology.yaml) and writes a structured report to ontology/pr26_ontological_issues.json.

6 issues enumerated:

ID	Severity	Issue	Status
OE-PR26-001	high	Unicode chars in print() without encoding guard	resolved
OE-PR26-002	medium	Integer projection weight update is a no-op placeholder	known limitation
OE-PR26-003	low	Hard little-endian requirement undocumented as platform boundary	accepted
OE-PR26-004	low	GITHUB_OUTPUT write in text mode adds \r\n on Windows	accepted
OE-PR26-005	low	update_weights_sequential() defined but never called	accepted
OE-PR26-006	low	safetensors int64 version dependency	accepted (>=0.4.0 already pinned)

Script exits 1 if any issue remains open, 0 otherwise.

Pull request overview

This PR fixes a critical Windows CI failure caused by Unicode encoding issues and adds a comprehensive enumeration of ontological issues found in the OE-IFM module. The fix ensures cross-platform determinism by standardizing stdout encoding to UTF-8 across all platforms.

Changes:

• Added PYTHONIOENCODING: utf-8 environment variable to CI workflow to prevent Windows Unicode encoding errors
• Created enumeration script that systematically scans code for ontological issues using the Orthogonal Engineering failure ontology framework
• Generated structured JSON report documenting 6 identified issues (1 resolved, 5 accepted)
