+
 1. A master-key derivation function using Argon2id with parameters mandated by `docs/ARCHITECTURE/02-security-and-crypto.md`.
 2. Cross-platform OS keychain bindings for secure credential persistence (Windows, Linux). Android is deferred to the Flutter KeyStore bridge.

 3. **Use `ring` or `sodiumoxide`** — neither provides Argon2id natively; would still need the `argon2` crate.
 
 For keychain:

 1. **Direct Win32 / libsecret FFI** — full control, but significant per-platform maintenance burden.
 2. **`keyring` crate** — abstracts Windows Credential Manager, Linux SecretService, and macOS Keychain behind a single API.

 **Chosen Options:**
-- `argon2` crate v0.5 (RustCrypto) for KDF — spec-compliant, zero-copy output, and widely audited.

-- `keyring` crate v3 for cross-platform OS keychain — minimal code, covers Windows + Linux targets. Android is excluded via `cfg(not(target_os = "android"))` and will be handled by the Flutter KeyStore bridge.

+- (Δt): Proximity decay function yielding exponential values as due dates approach.
 - W_i, W_u, W_a: Configurable weighting coefficients for importance, urgency, and age accumulation.
 
 ## 2. Quadrant Assignment Mapping
+
 - **Quadrant I (Do First - Urgent & Important)**: Score >= Threshold_High AND Due_Date <= 48 Hours.
 - **Quadrant II (Schedule - Not Urgent & Important)**: Score >= Threshold_High AND (Due_Date > 48 Hours OR Due_Date IS NULL).
 - **Quadrant III (Delegate/Automate - Urgent & Not Important)**: Score < Threshold_High AND Due_Date <= 48 Hours.
