Brummel 138157767e design: forward-fix feature-acceptance contract anchor after plugin migration

The skill-system migration (c1441f3) moved skills/ out of the repo
to ~/dev/skills/, but the feature-acceptance contract's ratifying
anchor still pointed at the now-gone `skills/brainstorm/SKILL.md`.
`every_contract_names_a_resolvable_ratifying_test` in
design_index_pin.rs (the test the honesty-rule wires to every
contract row) caught it.

Re-anchor to `CLAUDE.md` § "Feature acceptance: LLM utility" —
that section in the in-tree project discipline file IS the
ratification of the criterion; the brainstorm skill is the
out-of-tree mechanism that applies it at spec time. Two edits in
lockstep: design/INDEX.md row 81 and the "Ratified by:" line at
the bottom of the contract body.

Not iter-scoped (orthogonal to prep.3 of kernel-extension-
mechanics, which landed in 9339279).

AILang Design — Index

The sole addressable entry point. Every contract and model is reached from here. A contract is a prescriptive, test-linked invariant; a model is a whitepaper narrative. ratifying-test names the green test that proves a contract still holds. link is polymorphic: a design/ file, or the authoritative source //! header when the code is the single source of truth.

Project framing

Goal

AILang is a programming language for LLM authors. It compiles to LLVM IR. Performance: native, no GC for the MVP.

Optimised for:

Machine readability over human ergonomics. The source is structured.
Local reasoning. Every definition carries its full type and effects.
Provability. Pure core language, explicit effects, optional refinements.
Robustness against hallucinations. Symbols are hashable; tools can verify existence without spending context window.

Project ecosystem

AILang is not just a language but an ecosystem. The language on its own is only valuable when its surroundings make it usable, checkable, and extensible for its target user (LLM authors). The repo therefore contains several equally important components — none of them optional, all of them evolving in lockstep with the language:

Language core (crates/ailang-core, crates/ailang-check, crates/ailang-codegen): AST, type system, codegen.
Surface forms (crates/ailang-surface, crates/ailang-prose): the LLM-facing renderings of a module. ailang-surface is the lossless Form-A printer/parser — the canonical authoring surface, with a round-trip property parse ∘ print = id gating every release. ailang-prose is the lossy Form-B projection — human-readable prose for review and edit, with no parser; re-integration goes through the LLM-mediator round-trip documented in docs/PROSE_ROUNDTRIP.md.
CLI (crates/ail): toolchain for tooling consumers — manifest, describe, deps, check, build, parse, render, prose, merge-prose, etc., preferably with --json for machine consumption.
Examples (examples/): canonical .ail.json programs. They are specification anchors, not demos — the E2E suite hangs off them.
Skills (skills/): specialised disciplines (brainstorm, planner, implement, audit, debug, fieldtest) plus the agent rosters they dispatch (skills/<name>/agents/). They form the project's own development methodology and are versioned with the codebase. See skills/README.md.
Design ledger (design/): design/INDEX.md (this file — the sole addressable spine for canonical state), design/contracts/ (test-linked invariants), design/models/ (onboarding whitepapers).
Docs (docs/): specs/ (per-milestone design specs), plans/ (per-iteration implementation plans). Project history lives in git log; the forward queue lives in the Gitea issue backlog (http://192.168.178.103:3000/Brummel/AILang/issues).
Tests: unit tests per crate plus E2E in crates/ail/tests/e2e.rs. Every new compiler path needs a test, otherwise the feature does not count as done.

Project language: English

All in-tree content is written in English: source code (identifiers, comments, string literals, CLI help), design documents, agent prompts, READMEs, commit messages, examples, and CLAUDE.md. The live conversation between user and me stays German for ergonomic reasons; everything that lands in git is English. This keeps diffs and tooling output uniform and matches the audience for AILang (LLM authors), for whom English is the default.
