The per-iter journal under docs/journals/ duplicated the iter commit body's substance and accumulated as Verlauf-Doku with no Future-Use. Sweep across all live control documents: CLAUDE.md, the 7 SKILL.md files, the 11 agent files, design/INDEX.md and the contracts/models that referenced journals, docs/roadmap.md, and the handful of source comments + tests that pointed at journal files for rationale. Mechanism changes: - Standing-reading-lists in every agent now read `git log -N --format=full` for recent project state, never per-iter journal files. The architect reads `git log <prev-milestone-close>..HEAD --format=full` for audit scope. - implement-orchestrator no longer writes a journal file. DONE outcomes emit just code + stats; the end-report is the per-task summary the Boss uses to write the commit body. PARTIAL/BLOCKED outcomes emit BLOCKED.md at the repo root — uncommitted by convention, Boss removes on repair or discard. New iron-law line + four-rationalisation row + red-flag bullet codify it. - audit ratify mechanic: --update-baseline is now paired with an explicit ratify paragraph in the audit-close commit body, not a separate JOURNAL ratify entry. - design/contracts/honesty-rule.md: "history and rationale lives in docs/journals/" → "lives in git log (iter and audit commit bodies)". Pinned phrase preserved verbatim. - CLAUDE.md "Roles of …" section reframed: design/, git log, journal-archive.md (content-frozen), roadmap.md, specs/, plans/. No docs/journals/ slot anymore. - roadmap.md context-lines that pointed at per-iter journals are dropped where the spec/commit already carries the rationale, or rephrased to "shipped in the <iter> iter commit" / "docs/journal- archive.md (<date> entry)" for pre-2026-05-11 references. What stays (this commit): - docs/journals/ directory and contents are NOT touched. Removing the contents is a separate follow-up. - docs/journals/2026-05-19-design-decision-records.md still has live readers (docs_honesty_pin.rs Z 108 + parse.rs + duplicate_ctor_pin.rs + 3 roadmap mentions) — also follow-up. - docs/journal-archive.md still exists; its self-pointer header has been updated to drop the "see docs/journals/INDEX.md" mention. Workspace builds, full test suite green.

# 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](contracts/authoring-surface.md), 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/`): `docs/journal-archive.md` (archived monolith
|
|
for pre-2026-05-11 history, content-frozen), `roadmap.md` (forward
|
|
queue), `specs/` (per-milestone design specs), `plans/` (per-
|
|
iteration implementation plans). Current iter / audit history
|
|
lives in `git log`.
|
|
- **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.
