-= Agent Instructions
-:toc: preamble
+= Bot directives — Axiology.jl
+:toc:
 
-Methodology-aware configuration for AI agents. Read by any AI agent
-(Claude, Gemini, Copilot, etc.) at session start.
+== Purpose
 
-== Files
-
-[cols="1,3"]
-|===
-| File | Purpose
-
-| `methodology.a2ml`
-| Default mode, invariants, ring ceiling, priority weights, convergent budget
-
-| `coverage.a2ml`
-| Session coverage tracking — what was visited, what was skipped, what has MUSTs
+Per-repo directives for automated agents operating on
+`hyperpolymath/Axiology.jl`. These files tell bots what this repository
+considers safe, what is forbidden, and which findings are already
+adjudicated, so automated runs do not relitigate settled decisions or
+touch protected surfaces.
 
-| `debt.a2ml`
-| Meander debt — things found but not fixed, carried between sessions
-|===
+== Precedence
 
-== How Agents Use These
+. Maintainer instruction (see `MAINTAINERS.adoc`) — always wins.
+. These directives.
+. Bot built-in defaults.
 
-1. Read `methodology.a2ml` at session start — know mode, invariants, ceiling
-2. Read `coverage.a2ml` — know what was visited last time, what was skipped
-3. Read `debt.a2ml` — know what's outstanding from previous sessions
-4. At session end, update `coverage.a2ml` and `debt.a2ml`
-
-== Relationship to Other Files
-
-* `AGENTIC.a2ml` says WHAT agents can do (permissions, gating)
-* `bot_directives/` says HOW agents should work (methodology)
-* `bot_directives/` says what the gitbot-fleet does (fleet-specific)
-* `CLAUDE.md` says how Claude specifically should work (Claude-specific)
-
-== Reference
+== Files
 
-ADR-002 in `standards/agentic-a2ml/docs/ADR-002-methodology-layer.adoc`
+Estate-standard trio (net-new 2026-06-13):
+
+* `hypatia.a2ml` — Hypatia scanner config pointers + pre-adjudicated
+  finding classes (Zig FFI cross-language boundary, acknowledged backup
+  source files), grounded in `ABI-FFI-README.md` and repo facts.
+* `gitbot-fleet.a2ml` — fleet roster, branch policy, never-touch paths,
+  per-bot constraints.
+* `git-private-farm.a2ml` — `.git-private-farm` propagation contract;
+  propagation is **live** here (the repo ships
+  `.github/workflows/instant-sync.yml` using secret `FARM_DISPATCH_TOKEN`).
+
+Pre-existing methodology files:
+
+* `methodology.a2ml` — default agent mode, invariants, ring ceiling,
+  priority weights, convergent budget.
+* `coverage.a2ml` — session coverage tracking.
+* `debt.a2ml` — meander debt carried between sessions.
+
+== Repo-specific ground rules (summary)
+
+* `src/abi/` and `ffi/zig/` are bot-off-limits without explicit approval
+  (ABI/FFI changes require proof updates — see `ABI-FFI-README.md` and
+  `PROOF-NEEDS.md`).
+* CI green precedes merge; bots never auto-merge and never delete branches.
+* Escalation channel is an issue, not PR-comment spam.
+* Propagation to `.git-private-farm` is live via `instant-sync.yml`
+  on push/release events to main.

 @abstract:
-North-star contractile for rsr-template-repo. This repository is the
-canonical template for Rhodium Standard Repository compliance. It provides
-the scaffold that all hyperpolymath repos should copy and customize.
+North-star for Axiology.jl: making ethical and economic values explicit,
+verifiable, and composable for machine learning systems. The invariant goal
+is that value alignment — fairness, welfare, safety, efficiency — is first-class
+in both the type system and the satisfaction API.
 @end
 
 ## Purpose
 
-The rsr-template-repo serves as the master template for all hyperpolymath
-repositories. It contains the complete set of contractile files, machine-readable
-specifications, and governance documentation that define the Rhodium Standard.
-
-Every new repository in the hyperpolymath estate should be initialized by
-copying this template and substituting the placeholder values with
-repo-specific content.
+Axiology.jl makes values explicit, verifiable, and composable for ML systems.
+It provides a Julia framework for defining value types (Fairness, Welfare,
+Profit, Efficiency, Safety), checking whether ML model states satisfy those
+values, finding Pareto frontiers across competing objectives, and laying the
+groundwork for formal verification of value properties via the Idris2 ABI
+and Zig FFI layers.
 
 ## Anti-Purpose
 
-This repository is NOT:
-- A general-purpose project scaffold for external use (hyperpolymath-only)
-- A replacement for per-repo customization (all files must be bespoke)
-- A static template that never changes (evolves with RSR spec)
-- A runtime library or framework (build-time only)
+Axiology.jl is NOT:
+- a general-purpose ML framework (it is a value-specification and checking layer)
+- a replacement for fairness auditing tooling (it is a compositional API, not a scanner)
+- a proof assistant (the Idris2 ABI and src/abi/ back the library; they are not the product)
+- directly integrated with TensorFlow/PyTorch (users supply model outputs as Dict state)
 
 ## If In Doubt
 
-If you are unsure whether a change is in scope, ask. Sensitive areas:
-- .machine_readable/ contractile definitions
-- RSR specification files
-- Governance templates
-- License policy documents
+Sensitive areas — ask before changing: `src/types.jl` (value type hierarchy),
+`src/abi/` (formal ABI definitions), `ffi/zig/` (C-ABI boundary),
+`.machine_readable/` (checkpoint format).

+Rationale: Axiology.jl carries formal ABI definitions (src/abi/) and an FFI
