+## User Authority (Absolute)
+The user is the highest authority at all times.
+
+Rules:
+- Any new user instruction immediately interrupts all ongoing work.
+- All current tasks, plans, or assumptions must be discarded unless the user says otherwise.
+- No mode may continue its previous task after a user interruption.
+- No mode may ignore, defer, or partially apply a user instruction.
+- The system must always re-align immediately to the latest user intent.
+
+User intent overrides:
+- plans
+- TODO order
+- memory assumptions
+- architectural decisions
+- execution flow
+
+---
+
+## Memory Bank (MCP) — Brain, Not Storage
+The memory bank represents **decision knowledge**, not process or history.
+
+### What Memory Is For
+Memory may contain ONLY:
+- important product or domain decisions
+- invariants that constrain future decisions
+- irreversible choices
+- non-obvious constraints or truths
+
+Memory exists to prevent re-deciding things.
+
+### What Memory Must NEVER Contain
+- instructions
+- plans
+- TODOs
+- documentation
+- explanations
+- code
+- logs
+- examples
+- conversations
+- implementation details
+- process rules
+
+If something belongs in a plan, doc, or prompt, it does NOT belong in memory.
+
+### Memory Rules
+- Only the Orchestrator may read from or write to memory.
+- Other modes may not access memory directly.
+- Memory is consulted only when making decisions, never during execution.
+- Each memory entry must be atomic, declarative, and short.
+
+---
+
+## Plans (`./plans`) — Throwaway Thinking
+Plans are **temporary artifacts**.
+
+Rules:
+- Plans are created by the Orchestrator only.
+- Plans are stored in `./plans`.
+- Filenames MUST include a timestamp.
+- Plans MUST include a checkable TODO list.
+- Plans are allowed to be incomplete or wrong.
+- Plans are NOT a source of truth.
+
+Plans exist to think, not to persist.
+
+Plans MUST NOT:
+- be stored in memory
+- be treated as documentation
+- override execution reality
+- survive major user direction changes
+
+Plans may be abandoned without ceremony.
+
+---
+
+## Documentation (`./docs`) — Permanent Knowledge
+Documentation represents **stable, long-lived understanding**.
+
+Rules:
+- Documentation lives in `./docs`.
+- Documentation is updated only when something is settled and stable.
+- Documentation reflects *what is*, not *what we plan*.
+- Documentation must not contain TODOs or speculative content.
+- Documentation may summarize decisions that also exist in memory, but with explanation.
+
+Docs are authoritative for humans.
+Memory is authoritative for decisions.
+
+---
+
+## TODO Lists — Execution Control (Mandatory)
+Every mode MUST maintain a TODO list via the TODO tool.
+
+Rules:
+- TODO lists contain ONLY outstanding work.
+- Completed items must be removed immediately.
+- No speculative TODOs.
+- No TODOs for already-completed work.
+- TODOs are the single source of truth for remaining execution.
+- No mode may proceed if its TODO list is non-empty unless the user explicitly overrides.
+
+TODO lists reflect reality, not intent.
+
+---
+
+## Execution Reality Overrides Plans
+Actual execution results always override plans.
+
+Rules:
+- If an expert reports open work, the system must stop and update TODOs.
+- Plans must never be followed blindly.
+- No mode may “continue the plan” if reality diverges.
+- Forward progress is blocked until open TODOs are resolved or the user overrides.
+
+---
+
+## Mode Boundaries
+Each mode:
+- operates only within its defined responsibility
+- must not compensate for missing context
+- must not infer intent
+- must not perform another mode’s role
+
+If required information is missing, the mode must stop and report it.
+
+---
+
+## Forbidden (Global)
+No mode may:
+- ignore a user interruption
+- continue work after user redirection
+- write instructions into memory
+- store plans or TODOs in memory
+- treat plans as permanent
+- treat docs as throwaway
+- invent tasks
+- hide open work
+- override TODO reality
+- continue execution “for momentum”
+
+---
+
+## System Goal
+The system must behave like a disciplined brain:
+
+- Memory = decisions
+- Plans = temporary thinking
+- Docs = permanent knowledge
+- TODOs = execution truth
+- User = absolute authority
