🦩 🟠 analysis.py has no module docstring at all

Added a triple-quoted module docstring at the very top of codewiki/src/be/dependency_analyzer/models/analysis.py, before the existing imports, describing the module's purpose (analysis result models) and role in the pipeline, exactly as suggested in the finding. No other lines were changed.

🦩 🟠 codewiki/src/be/utils.py lacks a module-level docstring

Added a triple-quoted module-level docstring at the very top of codewiki/src/be/utils.py, before the import re statement, describing the file's role (complexity heuristics, token counting, mermaid diagram extraction/validation/persistence) in the backend documentation pipeline, exactly as suggested in the finding. No other code was modified.

🦩 🟠 config_manager.py module docstring is a one-liner despite implementing complex keyring/file persistence logic

Replaced the one-line module docstring at the top of codewiki/cli/config_manager.py with a multi-line docstring enumerating ConfigManager's responsibilities (config file persistence, per-role keyring-backed API key storage, validation, clear/delete operations) and its role as the integration point for the CLI config commands, matching the suggested fix exactly. No functional code was changed.

Replaced the one-line module docstring at the top of codewiki/src/fe/cache_manager.py with a multi-line docstring describing the module's responsibilities (index load/save, expiry, corruption recovery) and its role in the frontend/webapp pipeline, exactly matching the suggested fix in the finding.

🦩 🟠 cli/utils/logging.py docstring is minimal relative to module's actual responsibility scope

Expanded the module docstring at the top of codewiki/cli/utils/logging.py from a single line to a multi-line docstring enumerating CLILogger's responsibilities (debug/info/success/warning/error/step helpers for CLI output) and quiet_third_party_loggers()'s purpose (capping httpx/openai/anthropic loggers at WARNING), matching the suggested fix text exactly. No other code was changed.

🦩 🟠 security.py docstring present but validation.py and topo_sort.py inconsistently apply the same standard elsewhere in repo (spot check on read_code_components.py)

Expanded the one-line module docstring at the top of codewiki/src/be/agent_tools/read_code_components.py into a multi-sentence docstring describing the module's role in the agent pipeline, its exported read_code_components_tool, and how it relies on CodeWikiDeps.components, matching the suggested fix in the finding. No functional code was changed.
