Sync Wolverine Trading SQL practice entries

[tomtoto757]

Tech-OA is missing two verified Wolverine Trading practice routes with a latest sighting of Aug 30, 2026:

• Add Market Share Ticker with Imbalance.
• Add Hedges Outperforming Their Trades.

Both entries use the public catalog's explicit tabular format and therefore appear as SQL. Wolverine Trading already appears exactly once in the company list, so that list remains unchanged. This focused change keeps README.md as the sole edited file; no problem statements, solutions, media, application code, dependencies, or workflows are included.

The latest base sync also left eight freshness glyphs stale. Running the repository's required freshness script updated those markers without moving any row. After marker normalization, the semantic diff is exactly the SQL count change from 3 to 5 and the two Wolverine entries.

Validation:

• python3 scripts/refresh-freshness.py: passed and is idempotent with 0 marker changes and 0 reordered positions on the final commit.
• PYTHONDONTWRITEBYTECODE=1 python3 -m unittest discover -s scripts -p 'test_*.py' -v: all 11 tests passed.
• git diff --check origin/master...HEAD: passed.
• Complete table guards passed: 2,141 rows and 2,141 unique routes, paired links match, dates descend stably, and all 2,139 base rows retain content and relative order after freshness-marker normalization.
• Format counts match the README: Coding 1,807; SQL 5; System design 250; Low-level design 51; AI coding 28. The public 2,829-item catalog maps both target routes to SQL, and an in-memory format projection places both only in the five-row SQL view.
• The company list remains unique, alphabetically ordered, and contains Wolverine Trading exactly once.
• README.md is 495,468 bytes, below the 500,000-byte limit.
• Both public pages and APIs returned HTTP 200 with exact canonical routes, titles, Wolverine Trading attribution, published status, OA stage, tabular format, and Aug 30 latest sighting.

Independent regression review approved final commit d70cd6c9d55441da873df60689a976979f9b76ec against latest base 8227a0dbbf2695c60f4c758e0793d91fa7c10d06. Separate reviewer /root/wolverine_catalog/wolverine_tech_oa_review examined the complete diff, repository contribution rules, freshness behavior, native scripts and tests, all-row invariants, public catalog projection, page/API metadata, and publication boundaries. The reviewer independently reran the checks in a disposable copy and reported no blocking findings.

Residual limits are the remaining 4,532 bytes of README headroom and the point-in-time nature of public HTTP verification. This PR remains a draft for maintainer review; no merge is requested.
