Rewrites docs/env_reference.md and ModularBot_garage/.env.example so a reader
can act on the file without re-deriving anything, and so every claim in it
can be checked.
WHAT
177 knobs documented across a 6-block format:
WHAT / VALUES / STATUS / GOTCHA / TRY. Values are the built-in defaults,
so `.env.example` is behaviourally identical to a clean run. No default
value changed anywhere; the only added key is TR_FIRE_LAG=0, which is real
(fire_tracker.nim:164).
WHY (traceability)
Every STATUS line now cites the job or commit behind the claim it makes.
A documented default is only useful if you can tell whether it was
verified or copied by hand; the citation makes that decidable without
re-running the experiment.
The presence-gated list was wrong: it claimed 7 knobs, the true number is
10. Three knobs were also wrongly labelled presence-gated; they are
value-based and are now documented as such.
All 31 `# TRY:` example values were checked against the code that parses
them, so no example is rejected when copied.
VERIFICATION
Round-trip (j172 probe: printEnvReport clean vs .env.example applied
through the repo's own env_dotenv loader, reports diffed): 0 mismatches,
0 warnings, 0 dropped keys (177 in file, 177 seen). Re-run after this
commit's comment edit, unchanged.
test_tfil_commit_env 159 PASS / 0 FAIL
test_env_report 25 PASS / 0 FAIL
test_tfil_ring_weights 24 PASS / 0 FAIL (earlier in the series)
Also drops the stale "snapshot of commit 5e32ec1" pin from .env.example: a
pinned hash goes stale the moment the next commit lands, which makes the
"regenerate when a default changes" instruction worse than none. The line
now just says the values mirror current defaults.
