+# Deprecated: PR #127 + #128 — JSON Hydrate Endpoints
+
+**Date**: 2026-02-17
+**PRs**: #127 (POST /api/v1/hydrate), #128 (POST /api/v1/qualia/hydrate + write-back)
+
+## Why deprecated
+
+1. **JSON is forbidden on the internal hot path.** Internal operations use
+   `&self` / `&mut self` borrows on shared substrate. Zero serialization.
+   
+2. **text_to_dn() is hash soup.** DN addressing must carry semantic meaning.
+   The SPOQ model requires positions in the DN tree to represent viewpoints,
+   not random hashes of message strings.
+
+3. **Hollow pipeline.** PR #127 manually constructed FeltPath, ReflectionResult,
+   and VolitionalAgenda with empty data and hardcoded defaults. PR #128 tried
+   to fix this but used `match i % 8` for ghost type assignment (random noise).
+
+4. **Wrong paradigm.** The hydrate endpoint assumed crewai-rust calls ladybug-rs
+   via HTTP. The correct architecture: one binary, shared `&BindSpace`, blackboard
+   borrow pattern (grey matter reads / white matter writes).
+
+## What to salvage
+
+- The `AgentState::compute()` integration pattern is correct (PR #126 has it)
+- The route from message → qualia is right, but should be `&Container` → `&Container`, not JSON
+- The INTEGRATION_SPEC Layer A concept (preamble for system prompt) is valid
+
+## Files
+
+- `server_hydrate_block.rs` — extracted 400-line code block from src/bin/server.rs
