strings.py DOX

Purpose

• Own the strings.py helper module.
• This module sanitizes, formats, truncates, and expands framework string content.
• Keep this file-level DOX profile synchronized with strings.py because this directory is intentionally flat.

Ownership

• strings.py owns the runtime implementation.
• strings.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Top-level functions:
• sanitize_string(s: str, encoding: str=...) -> str
• calculate_valid_match_lengths(first: bytes | str, second: bytes | str, deviation_threshold: int=..., deviation_reset: int=..., ignore_patterns: list[bytes | str]=..., debug: bool=...) -> tuple[int, int]
• format_key(key: str) -> str: Format a key string to be more readable.
• dict_to_text(d: dict) -> str
• truncate_text(text: str, length: int, at_end: bool=..., replacement: str=...) -> str
• truncate_text_by_ratio(text: str, threshold: int, replacement: str=..., ratio: float=...) -> str: Truncate text with replacement at a specified ratio position.
• replace_file_includes(text: str, placeholder_pattern: str=...) -> str

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem reads, filesystem deletion.
• Imported dependency areas include: helpers, re, sys, time.

Key Concepts

• Important called helpers/classes observed in the source: s.encode.decode, join, join.rstrip, re.sub, skip_ignored_patterns, match.group, s.encode, sys.stdout.write, sys.stdout.flush, time.sleep, c.isupper, result.islower, word.capitalize, files.fix_dev_path, files.read_file, re.match, formatted.split, c.isalnum, format_key.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_model_search.py
  • tests/test_whatsapp_number_utils.py
