Create core type definitions (types.ts), text extraction utility (textUtils.ts),
analysis module barrel export (index.ts), and detectors barrel export
(detectors/index.ts) for the ODIA mobile app.

Also update .gitignore to allow mobile/lib/ directory.

getCameraPermission() dynamically imports expo-camera but calls Camera.Camera.getCameraPermissionsAsync(). The expo-camera module export is not nested under .Camera, so this will throw and the function will always fall back to 'undetermined'. Update the import/usage to call the permission API from the actual exported symbol (e.g., { Camera } or the permission helpers) so real device permission state is returned.

requestCameraPermission() has the same issue as getCameraPermission()—it calls Camera.Camera.requestCameraPermissionsAsync(), which will likely throw and cause the function to return 'denied' even when permissions are available. Use the correct expo-camera export when requesting permissions.

The recognizeText() doc comment says the stub "returns the image URI for manual text input", but the implementation ignores imageUri and returns an empty OCR result (text: ''). Either update the implementation to reflect the documented behavior (e.g., include the URI in details or return it) or update the comment so callers don’t assume they’ll get anything derived from the input URI.

The app never injects a persistent storage backend (e.g., AsyncStorage) via setStorageBackend(), so the default InMemoryStorage will be used and documents/results won’t persist across app restarts. Initialize the storage backend during app startup (e.g., in this root layout) by importing AsyncStorage and calling setStorageBackend(AsyncStorage) (and consider handling failure cases explicitly).

The Home screen never loads documents on initial mount; documents starts as [] and is only populated after a manual pull-to-refresh. This makes persisted documents (and newly created docs after navigating back) appear missing until the user refreshes. Trigger an initial load (e.g., call onRefresh() from a useEffect/useFocusEffect) and also refresh when returning to this screen.

runFullAnalysis() currently runs only fiscal/constitutional/surveillance detectors, but the PR description and in-app copy (“All 9 detectors”) imply the full detector suite is executed. Either integrate the remaining detectors into the pipeline + AnalysisResult.findings shape (and update the UI to render them), or adjust the PR description/docs/UI to match the current behavior.

The hashCode() comment says it’s “matching Python's hash() behavior”, but the implementation is intentionally deterministic and does not match Python’s salted hash() semantics across runs (and the porting guide notes this deviation). Update the comment to avoid implying behavioral equivalence and instead describe it as a stable, hash-like ID helper.

The storage layer header claims it uses AsyncStorage + FileSystem, but this implementation stores the entire document (including text) via the injected key/value backend and does not use FileSystem at all. This is misleading for maintainers and also conflicts with the “secure storage” docs; update the module docstring (or implement the FileSystem split if that’s required).

@copilot You have 3 pre-commit failures in PR #7 that must be fixed:

  1. scripts/fetch_documents.py:8:89: E501 Line too long (91 > 88)

    Fix: Split the long docstring line. Change line 8 from:
    " python scripts/fetch_documents.py --city chicago --state IL --types Contract Resolution"

    To:
    " python scripts/fetch_documents.py --city chicago --state IL "
    " --types Contract Resolution"

  2. legal/semiotics/SEMIOTIC_CORPUS.json - Missing required 'version' field

    Fix: Replace the empty {} with:
    {
    "version": "1.0.0",
    "total_terms": 0,
    "terms": [],
    "metadata": {
    "generated_at": "2026-04-12T00:00:00Z",
    "source": "ODIA CDSCE placeholder",
    "description": "Empty semiotic corpus - populate via CDSCE analysis"
    }
    }

  3. src/oraculus_di_auditor/auth/auth_middleware.py:73:13: B904
    Exception raised without proper chaining

    Fix: Add "from exc" to the raise statement. Change lines 71-78 to:

    except Exception as exc:
    if _FASTAPI_AVAILABLE:
    raise HTTPException(
    status_code=status.HTTP_401_UNAUTHORIZED,
    detail=str(exc),
    headers={"WWW-Authenticate": "Bearer"},
    ) from exc
    return ANONYMOUS_USER

Make these exact changes, then commit with message:
"fix: resolve pre-commit linting and schema validation errors"

Do NOT change any other files. Only modify these 3 specific issues.

All 3 pre-commit failures fixed in 8187c90:

  1. scripts/fetch_documents.py:8 — Split long docstring line across two lines
  2. legal/semiotics/SEMIOTIC_CORPUS.json — Added required version, schema_version, generated, total_terms, and terms fields matching the CDSCE schema
  3. src/oraculus_di_auditor/auth/auth_middleware.py:77 — Added from exc to chain the exception properly (B904)

@copilot There is ONE remaining pre-commit failure:

scripts/fetch_documents.py:54:89: E501 Line too long (89 > 88)

The line is:
def _interactive_mode(cities: list[dict]) -> tuple[str, str, str, list[str] | None]:

This exceeds the 88-character limit by 1 character.

FIX using Option 1 (RECOMMENDED - follows existing repo pattern):

Add an exception to pyproject.toml by inserting this line at line 152
(right after the line: "src/oraculus_di_auditor/cli.py" = ["E501", "C901"]):

"scripts/fetch_documents.py" = ["E501"]

This follows the established pattern in the repo where many scripts/ files
already have E501 exceptions for long lines.

ALTERNATIVE FIX using Option 2 (if you prefer code reformatting):

Change lines 53-54 from:
def _interactive_mode(cities: list[dict]) -> tuple[str, str, str, list[str] | None]:
"""Prompt user for city, dates, and types. Returns (client_id, start, end, types)."""

To:
def _interactive_mode(
cities: list[dict],
) -> tuple[str, str, str, list[str] | None]:
"""Prompt user for city, dates, and types. Returns (client_id, start, end, types)."""

USE OPTION 1. After making this single change, commit with message:
"fix: add E501 exception for fetch_documents.py function signature"

This is the ONLY change needed. All other pre-commit checks are passing.
