A pre-existing INPUT.json or valid JSON INPUT file in local storage gets its metadata inferred from the parsed value. Scalars then read back as plain text or bytes, so false, 42, and null lose their JSON types.

This keeps successful JSON parsing as the source of the content type. The tests cover both filenames, scalar and falsy values, object/array controls, unchanged input bytes, explicit metadata, and malformed JSON. Existing metadata is respected; this does not rewrite sidecars created earlier.

Tested: uv run poe check-code (lint, type check, 767 unit tests) and the focused filesystem/Actor/storage tests (75 passed).

Prepared with Codex assistance.

value is now used only to choose the content type, and the .json suffix check appears twice. Setting content_type in each branch removes the is_json flag and infer_mime_type, with the same result:

if record_path.suffix == '.json':
    json.loads(content.decode('utf-8'))  # Raises on malformed JSON.
    content_type = 'application/json; charset=utf-8'
elif record_path.suffix == '.txt':
    content_type = 'text/plain; charset=utf-8'
elif record_path.suffix == '':
    try:
        json.loads(content.decode('utf-8'))
    except (json.JSONDecodeError, UnicodeDecodeError):
        content_type = 'application/octet-stream'
    else:
        content_type = 'application/json; charset=utf-8'
else:
    content_type = 'application/octet-stream'

This bug is older than the PR. A bare INPUT with non-UTF-8 bytes raises UnicodeDecodeError from open(). _actor._read_input_file catches both errors and returns the bytes, so this path should do the same.

Suggested change

	except json.JSONDecodeError:
	except (json.JSONDecodeError, UnicodeDecodeError):

Nothing tests a bare INPUT that is not JSON (for example b'hello', and a binary payload if the UnicodeDecodeError fix goes in). It should keep application/octet-stream and read back as bytes. A separate test fits better, because this one writes json.dumps(...).

13 values x 2 file names gives 26 cases. One object, 0, False, None, '' and 1.5 cover the same paths, including the falsy and bool/int cases.
