 ### 2.3 Identity Agnostic Resolution
-To support external systems using different coding standards (e.g., ISO Numeric vs Alpha-2), the V3 API will implement an "Any-Match" resolver.
+To support external systems using different coding standards, the V3 API implements a multi-field "Any-Match" resolver.
 
 **Resolution Logic:**
 - Accepts a query string `q`.
-- Scans all "Identity" fields (e.g., `alpha_2_code`, `alpha_3_code`, `numeric_code`, `group`).
+- Iterates through `searchable_fields` defined in the lookup registry.
-- Returns the highest-priority hierarchical match found across the "Identity" fields.
+- Returns the highest-priority hierarchical match.
 
-### 2.4 Negative Overrides (The "Taiwan" Problem)
+### 2.4 Negative Overrides (The "Shadowing" Pattern)
-To "delete" or hide a global default for a specific account, the account creates an override record with `enable = 0`. Because the V3 query filters by `enable = 1` **after** the hierarchical ranking, the disabled override "shadows" the default, effectively removing the item from that account's view.
+To "delete" a global default for a specific account, the account creates an override record with the same `group` but `enable = 0`. The ranking query assigns `rank_priority = 1` to the account record, and the outer `WHERE enable = 1` then excludes it, effectively hiding the item for that account.
-
-### 2.5 Policy-Driven Whitelisting (The "Timezone" Problem)
-For tables with high-density global data (e.g., Timezones, Languages), accounts can implement an **Opt-In Policy** to avoid the bloat of managing hundreds of negative overrides.
-- **Mechanism:** A configuration record (e.g., `data_store` JSON or `account_cfg` flag) defines a list of "Active Groups".
-- **API Logic:** If a whitelist is defined for the account, the API injects an `AND group IN (:whitelist)` filter into the ranked query.
-- **Outcome:** A client can curate a list of 5 active timezones out of 400 without creating manual shadow records for the remaining 395.

-## 3. Prioritization Examples
+## 3. Implementation Standards
-*Context: User in Account 5 (OSIT) viewing Event 99. Searching for "US".*
 
-| Priority | Group | Account ID | For Type | For ID | Name | Outcome |
+### 3.1 Normalization Rules
-| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
+- **Underscore Naming:** All database columns must use underscores (e.g., `alpha_3_code`) instead of hyphens to ensure clean Python attribute access.
-| **1 (Winner)** | **US** | 5 | `event` | 99 | **US of America** | **Object Override** wins. |
+- **Group Population:** The `group` field must be physically populated in the table with a stable identity string (ISO codes, standard names).
-| 2 (Shadowed)| US | 5 | NULL | NULL | USA | Account preference ignored. |
+- **Physical Name Field:** While specialized fields (like `english_short_name`) may exist, a physical `name` field is required for Generic CRUD compatibility.
-| 3 (Shadowed)| US | NULL | NULL | NULL | United States | Global default ignored. |
+
-| 4 (Ignored) | FR | NULL | NULL | NULL | France | Different group. |
+### 3.2 View Requirements
-| 5 (Removed) | TW | 5 | NULL | NULL | Taiwan | `enable=0` makes this vanish. |
+- **Standard Joins:** All `v_lu_v3_*` views must join the `account` table to provide `account_id_random`.
+- **Hybrid Naming:** (Proposed) Views may use `COALESCE` to provide a default `name` from specialized fields if the physical `name` column is empty.
 
 ---
 
 ## 4. Implementation Roadmap
 
-### Phase 1: Normalization & Views
+### Phase 1: Normalization & Infrastructure
-- [ ] Audit all `lu_*` tables for current schema.
+- [x] Audit first batch of `lu_*` tables.
-- [ ] Create/Update `v_lu_*` views to map legacy columns to the uniform `group` structure.
+- [x] Establish `Lookup_Base` Pydantic models.
-- [ ] Ensure `id_random` is available for all lookups.
+- [x] Implement hierarchical `get_lookup_list_v3` logic.
+- [x] Register `/v3/lookup/` router.
 
-### Phase 2: V3 Lookup Router
+### Phase 2: Migration (Batch 1: High Priority)
-- [ ] Create `app/routers/lookup_v3.py`.
+- [x] `lu_v3_country` (Group: `alpha_2_code`)
-- [ ] Implement `GET /v3/lookup/{lu_type}/list` with Rank/Override logic.
+- [x] `lu_v3_country_subdivision` (Group: `code`)
-- [ ] Implement **Whitelist Support** via account context policies.
+- [x] `lu_v3_time_zone` (Group: `name`)
-- [ ] Implement `GET /v3/lookup/{lu_type}/resolve?q=VALUE`.
 
-### Phase 3: Migration (Batch 1: High Priority)
+### Phase 3: Migration (Batch 2: Contextual)
-- [ ] `lu_country` (Complexity: Multi-Identity codes)
-- [ ] `lu_country_subdivision`
-- [ ] `lu_time_zone` (Complexity: Requires Whitelist Phase 2)
-
-### Phase 4: Migration (Batch 2: Contextual)
 - [ ] `lu_post_topic`
 - [ ] `lu_user_status`
 - [ ] `lu_file_purpose`
 
+### Phase 4: Advanced Features
+- [ ] Implement **Whitelist Policies** via `data_store` JSON.
+- [ ] Implement Batch Update tools for managers.
+
 ## 5. Key Learnings & Decisions
-- **Deduplication:** The `PARTITION BY` strategy ensures the frontend never receives two records for the same logical lookup item.
+- **Deduplication:** The `PARTITION BY group` is the cornerstone of the system. Without a populated `group` field, the hierarchy collapses.
-- **Fail-Closed:** Account isolation must be maintained; a user should never see another account's overrides.
+- **Generic CRUD Compatibility:** We decided to maintain a physical `name` field to allow the Aether V3 UI to handle all lookups with zero custom code.
-- **Group vs Code:** Using `group` as the internal Aether cluster key avoids naming collisions with industry standard codes (ISO, etc).
+- **Fail-Closed:** Account isolation is enforced at the query level via the `account_id` filter.
