-
-A simple JSON validator that checks for the presence of a `"valid": true` field in JSON files.

-## Files
-- `json_validator_new.py` - The validation script
-- `test_valid.json` - Test file with valid JSON
+# Hermes Environment Diagnostic Utility
+Run: python3 hermes_env_check.py

 ## Verification
-Run: `python3 /root/.hermes/wizard-outputs/spark/json_validator_new.py /root/.hermes/wizard-outputs/spark/test_valid.json`
-Expected exit code: 0
+- Script executes successfully
+- JSON output is valid

-## Exit Codes
-- 0: Valid JSON with valid=true
-- 1: Invalid JSON or missing/false valid field
-- 2: File not found

-One read serves both halves of the verdict: the bytes that are hashed are the
-bytes that were parsed, so a file rewritten between the parse and the digest
-cannot be described as "valid" while a different document's hash is printed
-(Q80 measured the two-open form: two reads, and the printed digest belonged to
-the second one).
-
-Contract -- the repo's tools/ exit codes:
-
-  0  every input is a strict RFC 8259 JSON text; one ``VALID <path> SHA256=``
-     line per input.
-  1  every input was readable and at least one is not a JSON text: a syntax
-     error, a bare ``NaN`` / ``Infinity`` / ``-Infinity`` (RFC 8259 s6: "Numeric
-     values that cannot be represented in the grammar below (such as Infinity
-     and NaN) are not permitted" -- rejected here through ``parse_constant``),
-     a duplicate object member name (s4 says names SHOULD be unique; refused
-     unless ``--allow-duplicates``), or bytes that are not decodable JSON text.
-  2  could not grade: a usage error, or an input that could not be read
-     (missing, a directory, permission denied, a non-directory in the path).
-     Nothing is printed for *any* input when any input is ungradable -- a
-     substrate failure never wears a verdict, and no digest is emitted.
-
-A leading UTF-8 byte order mark is tolerated: the parsed text is the bytes
-decoded as ``utf-8-sig`` (RFC 8259 s8.1 lets a parser ignore a BOM, and the
-lane's ``jsonl_validate.py`` already reads ``utf-8-sig``). Any other encoding --
-UTF-16, UTF-32, Latin-1, binary -- is not a JSON *text* in the interchange
-encoding RFC 8259 s8.1 requires, and grades rc 1 as undecodable. Both are stated
-so neither is filed as a bug. ``--results PATH`` writes the run as JSON: the
-exact invocation, and each input's path, size, blob sha256 and verdict.

-# home, so it printed its three ticks and "All critical paths verified" rc 0 on
-# any tree, and it read nothing relative to itself. It now resolves
-#   - its own directory from $0 (so the sibling snippet.py it names is the one
-#     that shipped beside it, and a lone copy has no opinion to report), and
-#   - the profile home from --home, else $HERMES_HOME, else
-#     ~/.hermes/profiles/$HERMES_PROFILE (default profile: spark), with the
-#     Hermes root from --root, else the parent of the profile home's `profiles`
-#     directory, else the profile home's own parent,
-# so the same invocation fails on a tree that is missing the paths it names.
-#
-# Exit codes follow the repo's tools/ contract:
-#   0 = every required path exists
-#   1 = a required path is missing (each is printed on its own MISSING: line)
