Conversation
web_interface/blueprints/api_v3.py held 111 routes, 56 helpers and 181 functions in one module -- 9% of the core by line count and three times the next largest file. It becomes a package of nine route modules grouped by path segment, plus __init__.py for the shared imports, constants, Blueprint and helpers. Every route module decorates the SAME api_v3 Blueprint object, so endpoint names stay api_v3.<function>, the URL map is unchanged and app.py is untouched. Verified: 111 routes before, 111 after, byte-identical rules, endpoints and methods, and every endpoint still on the one blueprint. plugins 3,867 config 1,178 starlark 692 system 619 fonts 452 misc 398 wifi 361 display 326 backup 212 __init__ 1,787 (imports, constants, Blueprint, 56 helpers) Two things the URL-map check could not catch, both found by running the suite: 1. PROJECT_ROOT = Path(__file__).parent.parent.parent. Moving the code one directory deeper made that resolve to web_interface/ instead of the project root. Nothing failed at import; it surfaced as ~110 tests failing with 404s and "installation script not found", because every path built from it was one level too shallow. Now parents[3], and test_api_v3_url_map.py asserts PROJECT_ROOT/run.py exists so the next move cannot repeat it. 2. Module-attribute patching. Tests do monkeypatch.setattr(api_v3_module, "_BACKUP_EXPORT_DIR", ...) and a route module that binds such a name by value never sees the patch. The shared code therefore stays in __init__.py rather than moving to a _common submodule -- it has to live on the module the tests patch -- and the eleven names tests patch are read back through the package (_pkg.X) instead of bound by value. Those eleven were found by AST-scanning every setattr in the test tree, not by guessing; "time" is among them, used to drive a fake clock through the second-resolution credential-backup filenames. Test changes are confined to what genuinely moved: patch targets that now name the owning route module, imports of helpers, and six tests that scan the api_v3 source as a file and now read the package directory. Full suite: 4,278 passed, 68 skipped, 0 failed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014RRtqXDCnvnY6EQwhT5CV9
📝 WalkthroughWalkthroughThe monolithic API v3 module is split into a package with shared helpers and route modules. The package preserves one Flask blueprint and adds backup, configuration, display, font, health, system, Starlark, and Wi-Fi routes. Tests now scan the package and verify the complete route map.

In `@web_interface/blueprints/api_v3/__init__.py`:
- Around line 297-299: Update the recursive redaction logic in
_redact_credentials so every field whose key matches _looks_like_a_credential is
replaced with an empty value regardless of whether its value is scalar, a dict,
or a list; only recurse for non-credential fields.
- Around line 1240-1241: Update the error logging around the calendar
registration process to pass raw through redact_text before supplying it to
logger.error, while preserving the exit code and existing message context.
- Line 1602: Protect the complete manifest read-modify-write transaction in the
standalone handlers with one shared lock, covering the manifest read, mutation,
and _write_starlark_manifest replacement. Do not rely on a lock inside
_write_starlark_manifest alone, and ensure concurrent updates cannot overwrite
each other.
In `@web_interface/blueprints/api_v3/backup.py`:
- Around line 116-121: Validate the restore option payload before constructing
RestoreOptions: reject any keys outside the supported restore option names and
reject values that are not actual booleans, returning HTTP 400 for either case.
Remove the bool() coercion from the restore_config, restore_secrets,
restore_wifi, restore_fonts, restore_plugin_uploads, and reinstall_plugins
assignments while preserving their existing defaults for omitted keys.
In `@web_interface/blueprints/api_v3/config.py`:
- Line 156: Restore the user-facing validation messages in the schedule
configuration validation flow by replacing corrupted “_pkg.time” text with
“time” in all four affected strings, including those in
save_dim_schedule_config. Also restore the “Validate time formats” comments at
the identified validation sections without changing surrounding behavior.
In `@web_interface/blueprints/api_v3/display.py`:
- Line 230: Replace the invalid _pkg.time import in the
service_was_running/start_service path with the existing _pkg alias attribute
access used elsewhere in the file, while preserving the time_module name and
on-demand startup behavior.
In `@web_interface/blueprints/api_v3/fonts.py`:
- Around line 172-176: Update the font upload flow around validate_file_upload
and font_file.save to enforce the 10 MB per-file limit before writing the file.
Validate the uploaded content size independently of the filename and extension,
reject oversized files using the existing error path, and preserve saving for
valid uploads.
In `@web_interface/blueprints/api_v3/starlark.py`:
- Around line 464-479: Make the update flow around config.json and
_pkg._write_starlark_manifest(manifest) transactional: stage both changes or
snapshot existing contents and restore both persistence targets if either write
fails. Ensure a failed manifest write cannot leave config.json updated, and a
failed config write cannot leave the manifest updated, while preserving the
existing success and error responses.
In `@web_interface/blueprints/api_v3/wifi.py`:
- Line 276: Update the auto_enable assignment in the relevant API route to use
the file’s existing shared string-aware boolean coercion helper instead of
bool(), preserving correct handling for JSON boolean values and strings such as
"false".
- Around line 336-339: Update the boolean coercion in the request-handling
method around _enabled_raw and _force_raw so integer 1 is treated as True rather
than disabling the radio. Prefer the module’s shared coercion approach if
available; otherwise accept integer values consistently and reject invalid,
unrecognized inputs with a 400 response.

Serialize the complete manifest read-modify-write transaction.
The standalone handlers read and mutate the manifest before calling _write_starlark_manifest. That helper only performs an atomic replacement. Concurrent requests can therefore overwrite each other, causing one successful update to erase another. Use one shared lock around the read, mutation, and replacement. A lock inside _write_starlark_manifest alone is insufficient.

Require strict boolean restore options.
bool() converts every non-empty string to True. For example, "restore_secrets": "false" restores secrets.
Unknown keys also retain the True default. A typo such as "restore_secret": false therefore performs a broader restore than requested.
Reject unknown keys and non-boolean values with status 400 before constructing RestoreOptions.

Fix the corrupted _pkg.time text in the validation error messages.
An identifier rewrite during the package split replaced time with _pkg.time inside string literals. These four strings are returned to clients in HTTP 400 responses, so the API now emits text such as Invalid start _pkg.time for monday: ....

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
Fix the invalid import; it breaks on-demand start when the service is running.
_pkg is a local alias for the package, not an importable module name. import _pkg.time as time_module resolves the absolute module path _pkg, so it raises ModuleNotFoundError. This line runs whenever service_was_running and start_service are both true, so that path always returns 500 after the on-demand request was already written to the cache. Use the alias attribute that the rest of the file already uses.

Enforce the 10 MB per-file limit.
validate_file_upload() ignores max_size_mb and checks only the filename and extension. The route then calls font_file.save(), so files larger than 10 MB can reach assets/fonts unless another layer rejects them. Add a per-file size check before saving.

Make the standalone update transactional.
If _pkg._write_starlark_manifest(manifest) returns False, the route returns 500 after config.json contains the new values. The standalone GET reads that file, while the manifest still contains the old values. Reordering the writes only moves the same inconsistency to a config.json write failure. Stage both writes or snapshot and restore both persistence targets when either write fails.

In `@web_interface/blueprints/api_v3/wifi.py` at line 276, Update the auto_enable
assignment in the relevant API route to use the file’s existing shared
string-aware boolean coercion helper instead of bool(), preserving correct
handling for JSON boolean values and strings such as "false".

enabled = 1 turns the radio off.
The coercion accepts only True and specific strings. An integer 1 produces enabled = False. A client that sends {"enabled": 1} therefore disables the radio although it asked to enable it. That can drop the caller's connection to this web interface.
Accept integers, or reject non-boolean and non-recognized values with a 400 response.
🐛 Proposed coercion fix
- _enabled_raw = data['enabled']
- enabled = _enabled_raw is True or (isinstance(_enabled_raw, str) and _enabled_raw.lower() in ('true', '1', 'yes'))
- _force_raw = data.get('force', False)
- force = _force_raw is True or (isinstance(_force_raw, str) and _force_raw.lower() in ('true', '1', 'yes'))
+ enabled = _coerce_bool(data['enabled'])
+ force = _coerce_bool(data.get('force', False))
+ if enabled is None or force is None:
+ return jsonify({
+ 'status': 'error',
+ 'message': 'enabled and force must be booleans'
+ }), 400Add the shared helper near the top of the module:
_TRUE_TOKENS = ('true', '1', 'yes')
_FALSE_TOKENS = ('false', '0', 'no')
def _coerce_bool(value):
"""Return True/False for booleans, ints and known strings; None otherwise."""
if isinstance(value, bool):
return value
if isinstance(value, int):
return value != 0
if isinstance(value, str):
token = value.strip().lower()
if token in _TRUE_TOKENS:
return True
if token in _FALSE_TOKENS:
return False
return None📝 Committable suggestion

What
web_interface/blueprints/api_v3.pyheld 111 routes, 56 helpers and 181 functions in one module — 9% of the core by line count and 3× the next largest file. It becomes a package:plugins.py__init__.pyconfig.pystarlark.pysystem.pyfonts.pymisc.pywifi.pydisplay.pybackup.pyEvery route module decorates the same
api_v3Blueprint object, so endpoint names stayapi_v3.<function>, the URL map is unchanged, andapp.pyis untouched. Deliberately not per-domain blueprints, which would rename every endpoint.Verified: 111 routes before, 111 after, byte-identical rules, endpoints and methods; every endpoint still on the one blueprint. Pinned by
test/fixtures/api_v3_url_map.jsonandtest_api_v3_url_map.py, which asserts the whole map rather than a count — a count passes when one route is deleted and another added, which is exactly what a careless move produces.Two things the URL-map check could not catch
Both found by running the suite, not by reasoning about the diff.

PROJECT_ROOTsilently pointed one level too shallow.Correct from
blueprints/api_v3.py. Fromblueprints/api_v3/__init__.py— one directory deeper — it resolves toweb_interface/. Nothing failed at import. It surfaced as ~110 tests failing with 404s and "installation script not found", because every path built from it was wrong. Nowparents[3], with a test assertingPROJECT_ROOT/run.pyexists.2. Module-attribute patching.
Tests do
monkeypatch.setattr(api_v3_module, "_BACKUP_EXPORT_DIR", ...). A route module that binds such a name by value never sees the patch.So the shared code stays in
__init__.pyrather than moving to a_commonsubmodule — it has to live on the module the tests patch — and the eleven names tests patch are read back through the package (_pkg.X) instead of bound by value. Those eleven were found by AST-scanning everysetattrin the test tree rather than by guessing;timeis among them, used to drive a fake clock through the second-resolution credential-backup filenames.Test changes
