Brummel 93887aa03b workflow: replace docs/roadmap.md with Gitea issue backlog 
The forward queue moves out of the in-tree markdown file and into
Gitea issues at http://192.168.178.103:3000/Brummel/AILang/issues.
Labels: kind:{milestone,feature,todo,idea} + prio:{p1,p2,p3}
+ state:in-progress. Big chunks live as Gitea milestones
(containers) with full prose in the description; smaller items are
standalone issues. Browse-and-filter scales constant against
growing item count; the previous markdown file was 1059 lines, of
which ~850 were already-closed-entry verlauf (the same failure
class the JOURNAL cut removed).

Sync-drift Code<>Tracker mitigation: Soft-convention `closes #N`
/ `refs #N` in commit bodies — Gitea auto-closes the issue on
push. Captured in user-level CLAUDE.md (~/.claude/CLAUDE.md, not
in this commit) as the durable rule; no hook enforcement.

In-repo changes:

- docs/roadmap.md deleted.
- CLAUDE.md (project): Code-layout drops roadmap; /boss gating
  retargeted; Roles section rewritten with a new "Gitea issues"
  bullet (URL + tea-CLI snippet) and the closes-#N trailer note.
- skills/boss/SKILL.md: 10 sites retargeted, plus Step 1 now
  prescribes `tea issues ls --labels prio:p1` as the queue read.
- skills/brainstorm/SKILL.md: Step 7.5 no-override BLOCK now
  files a Gitea issue via `tea issues create` instead of
  appending a roadmap entry; spec deletion stays.
- skills/audit/SKILL.md + ailang-architect.md: deferral
  requirement and debt-heuristic retargeted; forward-intent
  belongs in the Gitea backlog.
- skills/fieldtest/SKILL.md, skills/docwriter/SKILL.md +
  ailang-docwriter.md: roadmap → backlog.
- design/contracts/honesty-rule.md: forward intent lives in
  the Gitea backlog (pinned phrases unchanged).
- design/INDEX.md: Docs bullet drops roadmap, adds the backlog
  URL.
- crates/ailang-core/tests/docs_honesty_pin.rs: two assert
  messages retargeted (assertion bodies unchanged).
- bench/architect_sweeps.sh: Sweep-4 TABU extended with
  `docs/roadmap\.md` so the deleted path cannot quietly regrow
  as a cross-reference in design/contracts/.

Verification:

- cargo build --workspace clean.
- cargo test --workspace: 647 passed, 0 failed, 2 ignored.
- bench/architect_sweeps.sh exit 0 (all five sweeps clean, incl.
  new TABU).
- grep over the live tree (excluding docs/specs/, docs/plans/)
  shows zero residual docs/roadmap.md refs.

Not touched: ~55 historical files under docs/specs/ and
docs/plans/ that mention docs/roadmap.md. Snapshot-character,
analogous to the JOURNAL-cut precedent — historical specs are
not mass-edited just because a live file was retired; their
mentions were correct at write time.

Raw Blame History

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.
