Brummel 54f0ced148 workflow: delete docs/journals/ and docs/journal-archive.md

Strict application of the "Future-Use, not Verlauf" criterion to the
two remaining journal artefacts:

- `docs/journals/` (110 files): the per-iter and audit journals from
  2026-05-11 onward. Pure history; no live reader after the previous
  sweep. Entire directory removed.
- `docs/journals/2026-05-19-design-decision-records.md`: the one file
  that had live readers (`docs_honesty_pin.rs:108`, `parse.rs:80`,
  `duplicate_ctor_pin.rs:8`, three roadmap.md mentions) and was framed
  as a "relitigation guard". On re-examination its three asserted
  pinned phrases ("Regions were considered and rejected", the
  "demands annotations *because*" rationale, the prose-render
  placeholder statement) are rationale-prose, not load-bearing
  invariants — the test pinned itself, not a system property. Any
  Decision that still holds lives in the code, `design/contracts/`,
  or `design/models/`. Removed with the rest.
- `docs/journal-archive.md` (pre-2026-05-11 history): content-frozen
  long-tail history with no live reader. Removed; if anyone ever
  needs the pre-cutoff rationale they can `git log --before=2026-05-11
  --grep=<keyword>`.

Live-file consequences:
- `docs_honesty_pin.rs` `design_md_present_tense_anchors_present`:
  the three `records.*` assertions and the `read("docs/journals/…")`
  are dropped; the contract/model anchor pins remain.
- `duplicate_ctor_pin.rs`: the "why-two-overlays rationale lives in
  docs/journals/…" comment is replaced with the rationale inline.
- `parse.rs`: the "form-refinement rationale lives in docs/journals/…"
  comment is dropped (the rule body already states the refinement).
- `roadmap.md`: the decision-records mention in the DESIGN.md →
  design/ entry's body is dropped; the journal-archive.md `context:`
  pointers across ~12 closed entries are either rephrased to point
  at the relevant iter/audit (no path), or simplified to a one-line
  comment when the iter name alone carries the story.
- `CLAUDE.md` Roles section: the `docs/journal-archive.md` slot is
  removed; vocabulary note rephrased.
- `design/INDEX.md`: the Docs bullet drops `journal-archive.md`.
- `skills/README.md` bootstrap-rationale pointer rephrased.

`docs/specs/` and `docs/plans/` (per-milestone specs and per-iteration
plans) are unaffected — they remain the structured-design artefacts
they were before this sweep.

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, 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/): roadmap.md (forward queue), specs/ (per-milestone design specs), plans/ (per-iteration implementation plans). Project 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.
