Searching encrypted columns currently works only because encryptData() is
AES-CBC with a fixed IV, i.e. deterministic. That determinism is what leaks
equality and shared prefixes, and it is why moving storage to AES-GCM would
break every lookup. This separates the two concerns.
- core/Security/BlindIndex.php: HMAC-SHA256 over a normalised value, keyed by
a secret pepper. Phone numbers have a small keyspace, so a bare SHA-256
would be reversible by enumeration; the pepper lives in the environment, not
the database. The scope string includes table and field so the same number
does not produce a matching index across tables.
Normalisation unifies local/international phone forms, lowercases emails and
folds Arabic alef/ya/ta-marbuta and diacritics for names.
- migrations/: nullable *_bidx columns plus indexes, and the missing
adminUser.status/approved_by/approved_at columns that admin approvals need.
- scripts/backfill_blind_index.php: restartable, batched, --dry-run capable,
touches only index columns.
- Admin lookups by phone/email now match the index, keeping the old ciphertext
comparison in the same query so search keeps working until the backfill runs.
bootstrap exposes $blindIndex as null when no pepper is configured.
Also: AdminCaptain/getCaptainDetailsById.php selected driver.education, a
column absent from this schema. The PDOException was uncaught, so the client
received an empty body with HTTP 200 — the "non-JSON response" seen when
opening a captain. It now omits the column, catches the error, reports it as
JSON, and requires an admin role.
Console: opening any sidebar section refetches its data instead of showing
what was loaded when the console started.

- Removed ALTER TABLE DDL statements from Admin/auth/register.php (belongs in migration scripts)
- Added validated CORS with configurable allowed origins via CORS_ALLOWED_ORIGINS env var
- Removed assignment in load_env.php (secrets no longer exposed in superglobal)
- Changed OTP storage in Admin/auth/login.php from plaintext to sha256 hash
- Updated Admin/auth/verify_login.php to hash user input before comparison
- Replaced hardcoded /home/siro-api/ paths with environment variables:
- ERROR_LOG_PATH, ENV_FILE_PATH, SECRET_KEY_PAY_PATH, SECRET_KEY_PATH
- Falls back to __DIR__-relative paths when env vars are unset
