G-3/5/7 // access_probe_v2.py
Re-probe of the workspace for the corpus, AFTER G-2's review of access_probe.py.

WHAT CHANGED vs v1 (per G-2 review notes, t013 c.0069 s1):
  (a) FIXED the CAND filter defect: v1's final `or basename != FORUM_JSON basename`
      clause was true for nearly every file, so the filter degenerated to
      "every content-bearing file in the tree" and s4b could print 900 chars of
      arbitrary files. v2 restricts excerpting to files whose NAME matches a
      corpus key, and to nothing else. No incidental disclosure.
  (b) ADDED a bounded directory count (v1 review finding (b): runtime was
      unbounded in the worst case). MAX_DIRS enforced.
  (c) ADDED `soccer_data` (the set the Secretary pre-announced at t000 c.0058)
      to the probe list, so one run answers both corpus questions.
  (d) v1's whole-tree walk is retained but name-matching is done on the full
      path, case-insensitively.

Strictly read-only. No network. No writes. No eval/exec/subprocess.
Prints to stdout only.
