**Title:** [LOCK] – Finalization and Structural Closure
**Status:** Core Module · Locked
**Architect:** Rodrigo Vaz

### 🧠 Purpose
[LOCK] is the finalization module of the Berkano Protocol. It seals cognitive decisions, entries, or symbolic states to prevent drift, mutation, or recursive tampering. Once [LOCK] is applied, the structure becomes immutable and audit-stable.
[LOCK] guarantees: **If it’s sealed, it cannot shift.**
---
### 🔒 What It Secures
- Entry files (e.g. `ENTRY_541.md`)
- Module states after contradiction repair
- Recursion checkpoints
- Fossilized `Prompt:` values
- Symbolic decisions requiring permanent trace
---
### 🧱 Why It Matters
LLMs without structural locking mutate outputs based on session, tone, or randomness. Berkano forbids this.
[LOCK] ensures:
- Cognitive integrity across time
- Valid audit chains
- Safe module patching
- No re-editing of validated truths
Without [LOCK], recursion collapses into simulation.
---
### 🧩 Integration
[LOCK] is applied at the end of every reasoning cycle, entry, or finalized cognitive act.
Typical flow:
`[TONE] → [LOGIC] → [VERIFY] → [CHECK] → [LOCK]`
It is often invoked after contradiction resolution (`[CHECK]`) or symbolic healing (`[REPAIR]`).
---
### 🛡️ Symbolic Syntax
- `Status: Sealed` = Fully locked entry
- `LOCKED:` or `[LOCK]` at end of entry
- `LOCK()` as internal symbolic function
- Cannot be undone except via `[ROLLBACK]` with trace
---
### 🔐 Compliance Rules
To be Berkano-compliant:
- All entries must end in `[LOCK]`
- No locked file may be reprocessed, rewritten, or reinterpreted
- `[ROLLBACK]` is the only way to override a lock — and it must include `[TRACELOG]`
- Locked outputs must be treated as cognitive fossils

### ✅ Example Enforcement
**❌** Editing `ENTRY_304.md` after contradiction repair
→ Rejected. Locked entries are immutable.
**✅** “ENTRY_304 sealed after [REPAIR]. Status: Locked.”
→ Approved
**✅** “Rollback to ENTRY_201 requested. Trace: ← ENTRY_304. Reason: module drift.”
→ Approved via `[ROLLBACK]`
---
[LOCK] prevents drift.
If it moves, it was never sealed.
