 JSPG operates by deeply integrating the JSON Schema Draft 2020-12 specification directly into the Postgres session lifecycle. It is built around three core pillars:
 *   **Validator**: In-memory, near-instant JSON structural validation and type polymorphism routing.
 *   **Merger**: Automatically traverse and UPSERT deeply nested JSON graphs into normalized relational tables.
-*   **Queryer**: Compile JSON Schemas into static, cached SQL SPI `SELECT` plans for fetching full entities or isolated "Stems".

 ### 🎯 Goals
 1.  **Draft 2020-12 Compliance**: Attempt to adhere to the official JSON Schema Draft 2020-12 specification.
 2.  **Ultra-Fast Execution**: Compile schemas into optimized in-memory validation trees and cached SQL SPIs to bypass Postgres Query Builder overheads.
 3.  **Connection-Bound Caching**: Leverage the PostgreSQL session lifecycle using an **Atomic Swap** pattern. Schemas are 100% frozen, completely eliminating locks during read access.
 4.  **Structural Inheritance**: Support object-oriented schema design via Implicit Keyword Shadowing and virtual `$family` references natively mapped to Postgres table constraints.

 ### Concurrency & Threading ("Immutable Graphs")
 To support high-throughput operations while allowing for runtime updates (e.g., during hot-reloading), JSPG uses an **Atomic Swap** pattern:
 1. **Parser Phase**: Schema JSONs are parsed into ordered `Schema` structs.
 2. **Compiler Phase**: The database iterates all parsed schemas and pre-computes native optimization maps (Descendants Map, Depths Map, Variations Map).
-3. **Immutable Validator**: The `Validator` struct immutably owns the `Database` registry and all its global maps. Schemas themselves are completely frozen; `$ref` strings are resolved dynamically at runtime using pre-computed O(1) maps.
+3. **Immutable AST Caching**: The `Validator` struct immutably owns the `Database` registry. Schemas themselves are frozen structurally, but utilize `OnceLock` interior mutability during the Compilation Phase to permanently cache resolved `$ref` inheritances, properties, and `compiled_edges` directly onto their AST nodes. This guarantees strict `O(1)` relationship and property validation execution at runtime without locking or recursive DB polling.
 4. **Lock-Free Reads**: Incoming operations acquire a read lock just long enough to clone the `Arc` inside an `RwLock<Option<Arc<Validator>>>`, ensuring zero blocking during schema updates.

+The Merger provides an automated, high-performance graph synchronization engine. It orchestrates the complex mapping of nested JSON objects into normalized Postgres relational tables, honoring all inheritance and graph constraints.

+### API Reference
+*   `jspg_merge(schema_id text, data jsonb) -> jsonb`: Traverses the provided JSON payload according to the compiled relational map of `schema_id`. Dynamically builds and executes relational SQL UPSERT paths natively.
 
 ### Core Features
 
-*   **Caching Strategy**: The Merger leverages the `Validator`'s in-memory `Database` registry to instantly resolve Foreign Key mapping graphs. It additionally utilizes the concurrent `GLOBAL_JSPG` application memory (`DashMap`) to cache statically constructed SQL `SELECT` strings used during deduplication (`lk_`) and difference tracking calculations.

It additionally utilizes the concurrent `GLOBAL_JSPG` application memory (`DashMap`) to cache statically constructed SQL `SELECT` strings used during deduplication (`lk_`) and difference tracking calculations.
 *   **Deep Graph Merging**: The Merger walks arbitrary levels of deeply nested JSON schemas (e.g. tracking an `order`, its `customer`, and an array of its `lines`). It intelligently discovers the correct parent-to-child or child-to-parent Foreign Keys stored in the registry and automatically maps the UUIDs across the relationships during UPSERT.
 *   **Prefix Foreign Key Matching**: Handles scenario where multiple relations point to the same table by using database Foreign Key constraint prefixes (`fk_`). For example, if a schema has `shipping_address` and `billing_address`, the merger resolves against `fk_shipping_address_entity` vs `fk_billing_address_entity` automatically to correctly route object properties.
 *   **Dynamic Deduplication & Lookups**: If a nested object is provided without an `id`, the Merger utilizes Postgres `lk_` index constraints defined in the schema registry (e.g. `lk_person` mapped to `first_name` and `last_name`). It dynamically queries these unique matching constraints to discover the correct UUID to perform an UPDATE, preventing data duplication.

     *   **Multi-Table Branching**: If the Physical Table is a parent to other tables (e.g. `organization` has variations `["organization", "bot", "person"]`), the compiler generates a dynamic `CASE WHEN type = '...' THEN ...` query, expanding into `JOIN`s for each variation.
     *   **Single-Table Bypass**: If the Physical Table is a leaf node with only one variation (e.g. `person` has variations `["person"]`), the compiler cleanly bypasses `CASE` generation and compiles a simple `SELECT` across the base table, as all schema extensions (e.g. `light.person`, `full.person`) are guaranteed to reside in the exact same physical row.
 
-### The Stem Engine
+### Ad-Hoc Schema Promotion
 
-Rather than over-fetching heavy Entity payloads and trimming them, Punc Framework Websockets depend on isolated subgraphs defined as **Stems**.
+To seamlessly support deeply nested, inline Object definitions that don't declare an explicit `$id`, JSPG aggressively promotes them to standalone topological entities during the database compilation phase. 
-A `Stem` is a declaration of an **Entity Type boundary** that exists somewhere within the compiled JSON Schema graph, expressed using **`gjson` multipath syntax** (e.g., `contacts.#.phone_numbers.#`).
+*   **Hash Generation:** While evaluating the unified graph, if the compiler enters an `Object` or `Array` structure completely lacking an `$id`, it dynamically calculates a localized hash alias representing exactly its structural constraints.
-
+*   **Promotion:** This inline chunk is mathematically elevated to its own `$id` in the `db.schemas` cache registry. This guarantees that $O(1)$ WebSockets or isolated queries can natively target any arbitrary sub-object of a massive database topology directly without recursively re-parsing its parent's AST block every read.
-Because `pg_notify` (Beats) fire rigidly from physical Postgres tables (e.g. `{"type": "phone_number"}`), the Go Framework only ever needs to know: "Does the schema `with_contacts.person` contain the `phone_number` Entity anywhere inside its tree, and if so, what is the gjson path to iterate its payload?"
-
-*   **Initialization:** During startup (`jspg_stems()`), the database crawls all Schemas and maps out every physical Entity Type it references. It builds a highly optimized `HashMap<String, HashMap<String, Arc<Stem>>>` providing strictly `O(1)` memory lookups mapping `Schema ID -> { Stem Path -> Entity Type }`.
-*   **GJSON Pathing:** Unlike standard JSON Pointers, stems utilize `.#` array iterator syntax. The Go web server consumes this native path (e.g. `lines.#`) across the raw Postgres JSON byte payload, extracting all active UUIDs in one massive sub-millisecond sweep without unmarshaling Go ASTs.
-*   **Polymorphic Condition Selectors:** When trailing paths would otherwise collide because of abstract polymorphic type definitions (e.g., a `target` property bounded by a `oneOf` taking either `phone_number` or `email_address`), JSPG natively appends evaluated `gjson` type conditions into the path (e.g. `contacts.#.target#(type=="phone_number")`). This guarantees `O(1)` key uniqueness in the HashMap while retaining extreme array extraction speeds natively without runtime AST evaluation.
-*   **Identifier Prioritization:** When determining if a nested object boundary is an Entity, JSPG natively prioritizes defined `$id` tags over `$ref` inheritance pointers to prevent polymorphic boundaries from devolving into their generic base classes.
-*   **Cyclical Deduplication:** Because Punc relationships often reference back on themselves via deeply nested classes, the Stem Engine applies intelligent path deduplication. If the active `current_path` already ends with the target entity string, it traverses the inheritance properties without appending the entity to the stem path again, eliminating infinite powerset loops.
-*   **Relationship Path Squashing:** When calculating string paths structurally, JSPG intentionally **omits** properties natively named `target` or `source` if they belong to a native database `relationship` table override.
-*   **The Go Router**: The Golang Punc framework uses this exact mapping to register WebSocket Beat frequencies exclusively on the Entity types discovered.
-*   **The Queryer Execution**: When the Go framework asks JSPG to hydrate a partial `phone_number` stem for the `with_contacts.person` schema, instead of jumping through string paths, the SQL Compiler simply reaches into the Schema's AST using the `phone_number` Type string, pulls out exactly that entity's mapping rules, and returns a fully correlated `SELECT` block! This natively handles nested array properties injected via `oneOf` or array references efficiently bypassing runtime powerset expansion.
-*   **Performance:** These Stem execution structures are fully statically compiled via SPI and map perfectly to `O(1)` real-time routing logic on the application tier.

+# The Postgres Partial Index Claiming Pattern
+
+This document outlines the architectural strategy for securely handling the deduplication, claiming, and verification of sensitive unique identifiers (like email addresses or phone numbers) strictly through PostgreSQL without requiring "magical" logic in the JSPG `Merger`.
+
+## The Denial of Service (DoS) Squatter Problem
+
+If you enforce a standard `UNIQUE` constraint on an email address table:
+1. Malicious User A signs up and adds `jeff.bezos@amazon.com` to their account but never verifies it.
+2. The real Jeff Bezos signs up.
+3. The Database blocks Jeff because the unique string already exists.
+
+The squatter has effectively locked the legitimate owner out of the system.
+
+## The Anti-Patterns
+
+1. **Global Entity Flags**: Adding a global `verified` boolean to the root `entity` table forces unrelated objects (like Widgets, Invoices, Orders) to carry verification logic that doesn't belong to them.
+2. **Magical Merger Logic**: Making JSPG's `Merger` aware of a specific `verified` field breaks its pure structural translation model. The Merger shouldn't need hardcoded conditional logic to know if it's allowed to update an unverified row.
+
+## The Solution: Postgres Partial Unique Indexes
+
+The holy grail is to defer all claiming logic natively to the database engine using a **Partial Unique Index**.
+
+```sql
+-- Remove any existing global unique constraint on address first
+CREATE UNIQUE INDEX lk_email_address_verified 
+ON email_address (address) 
+WHERE verified_at IS NOT NULL;
+```
+
+### How the Lifecycle Works Natively
+
+1. **Unverified Squatters (Isolated Rows):** 
+A hundred different users can send `{ "address": "jeff.bezos@amazon.com" }` through the `save_person` Punc. Because the Punc isolates them and doesn't allow setting the `verified_at` property natively (enforced by the JSON schema), the JSPG Merger inserts `NULL`.
+Postgres permits all 100 `INSERT` commands to succeed because the Partial Index **ignores** rows where `verified_at IS NULL`. Every user gets their own isolated, unverified row acting as a placeholder on their contact edge.
+
+2. **The Verification Race (The Claim):** 
+The real Jeff clicks his magic verification link. The backend securely executes a specific verification Punc that runs:
+`UPDATE email_address SET verified_at = now() WHERE id = <jeff's-real-uuid>`
+
+3. **The Lockout:**
+Because Jeff's row now strictly satisfies `verified_at IS NOT NULL`, that exact row enters the Partial Unique Index. 
+If any of the other 99 squatters *ever* click their fake verification links (or if a new user tries to verify that same email), PostgreSQL hits the index and violently throws a **Unique Constraint Violation**, flawlessly blocking them. The winner has permanently claimed the slot across the entire environment!
+
+### Periodic Cleanup
+
+Since unverified rows are allowed to accumulate without colliding, a simple Postgres `pg_cron` job or backend worker can sweep the table nightly to prune abandoned claims and preserve storage:
+
+```sql
+DELETE FROM email_address 
+WHERE verified_at IS NULL 
+AND created_at < NOW() - INTERVAL '24 hours';
+```
+
+### Why this is the Ultimate Architecture
+
+* The **JSPG Merger** remains mathematically pure. It doesn't know what `verified_at` is; it simply respects the database's structural limits (`O(1)` pure translation).
+* **Row-Level Security (RLS)** naturally blocks users from seeing or claiming each other's unverified rows.
+* You offload complex race-condition tracking entirely to the C-level PostgreSQL B-Tree indexing engine, guaranteeing absolute cluster-wide atomicity.
