James Dansereau dbea5a30fe chore(agentic): speed-ups plan Steps 1, 4 (N2/R8/R9), 6
Static/tooling slice of docs/dev/notes/AGENTIC-SPEEDUPS-PLAN.md — no build or
runtime environment needed to verify any of it.

- Step 6 / N7: add a VERIFY: line to the investigation-brief template
  (docs/dev-process.md) and the CLAUDE.md dispatch-preflight checklist — the
  brief must now name the exact probe/verify invocation that proves the task
  done, or state that runtime verification is impossible here.
- Step 4 / N2: tools_pc/README.md — indexes the ~60 scripts with a
  living vs artifact marker so closed-finding artifacts can be archived.
- Step 4 / R8: tools_pc/gen_findings_index.py -> docs/dev/findings-index.csv
  (label, bucket, one_liner, status_raw) — grep-before-you-read aid for the
  ~200 KB finding log. Heuristic parser of the §F/§H tables.
- Step 4 / R9: tools_pc/gen_env_probes.py — re-greps live getenv("GE_*")
  sites and reports NEW/GONE drift vs docs/dev/GE-ENV-PROBES.md (keeps the
  curated prose, only checks the site map). Doc reconciled: 7 new probes
  added, GE_D54 kept as a tombstone.
- CI: validate job now runs both generators with --check.

Step 1 / N1 (HANDOFF preflight) applied in the local-only docs/HANDOFF.md.
Step 2 (verify.sh) and the HANDOFF/HANDOFF-ARCHIVE trim are left for a
session with a build environment.

"""Drift check for docs/dev/GE-ENV-PROBES.md (speed-ups plan Step 4 / R9).
That doc is a hand-curated table of every `GE_*` env probe -- var, file:line,
what it does, live/dead. It was last snapshotted by a manual grep and drifts
as probes are added/removed. This script does NOT regenerate the prose (the
curation is the value); it re-greps the live `getenv("GE_...")` sites and
reports:
* NEW -- a var with live sites that the doc never names
* GONE -- a var the doc names that has no live site any more
* a fresh var -> file:line site map (paste into the doc's File:line cells)
Usage:
python tools_pc/gen_env_probes.py # print the drift report
python tools_pc/gen_env_probes.py --check # exit 1 if NEW or GONE
