[codex] Mark residual portfolio lane non-default

[saagpatel]

What

Adds one explicit non-default catalog contract for the final residual portfolio lane.

Why

The portfolio truth queue was otherwise clean, but one settled out-of-scope lane still surfaced as decision-needed because it had no explicit catalog contract.

Review Of What Was Built

• Added a single catalog entry using existing experimental disposition semantics.
• Regenerated local portfolio truth and confirmed decision-needed drops to zero.

Cleanup Review

No new code paths or attention states were added. This intentionally uses the existing catalog vocabulary rather than expanding the model.

Verification Summary

• uv run python -m src.cli report saagpatel --portfolio-truth --portfolio-truth-allow-empty-notion succeeded.
• jq check confirmed decision-needed is zero.
• uv run operator-os-seam-linter --truth output/portfolio-truth-latest.json --json passed.
• uv run pytest -q tests/test_portfolio_catalog.py tests/test_portfolio_pathing.py tests/test_portfolio_truth.py tests/test_weekly_command_center.py passed: 80 passed.
• uv run ruff check . passed.
• git diff --check passed.

Shipped Summary

The branch reduces default attention to active product/infra only, with no current decision-needed items in the local truth snapshot.

Next Phase

After merge, fast-forward local main, regenerate portfolio truth once from merged state, and run the seam-linter as the final baseline check.

Remaining Roadmap

• Keep future portfolio cleanup behind the default-attention contract so settled residue does not become operator work again.
