Surfaced while scoping an empirical test of Decision 6 (.ailx as the
AI authoring projection). The cross-model test depends on a structural
.ail.json <-> .ailx bijection being established and prominently anchored
in DESIGN.md first; otherwise measured form-preference is contaminated
by expressive-power gaps rather than authoring ergonomics. P2 entry
carries the smoke-test evidence and full IONOS-endpoint addressing
notes so the test can be picked up without redoing the connection work.
Five polymorphic prelude free fns (ne/lt/le/gt/ge) plus three E2E
fixtures: positive composition over Int/Bool/Str, user-ADT with
user-written Eq/Ord on IntBox, and Float-NoInstance with a
Float-aware diagnostic addendum cross-referencing DESIGN.md §"Float
semantics".
Two checker-side fixes were needed alongside the prelude additions,
both symmetric to the iter 23.4-prep visibility fix:
- linearity::check_module_with_visible — workspace-aware callee-mode
resolution so a Borrow-mode user fn forwarding into a prelude poly
fn (e.g. `at_most x y = not (gt x y)`) doesn't false-fire
consume-while-borrowed.
- mono::collect_mono_targets — distinguish rigid forall vars from
unbound metavars; rigid-bearing free-fn targets skip (they get
re-collected with concrete subst when the enclosing fn itself
monomorphises). Without this, a polymorphic body calling another
polymorphic free fn produced a spurious __Unit specialisation
whose body referenced compare at Unit.
Roadmap split: shipped Eq/Ord half checked, Show + print-rewire half
remains pending behind the heap-Str ABI prerequisite. DESIGN.md
§"Prelude classes" amended.
One pre-existing fixture (test_22b1_missing_method) renamed its
class method ne → tne to avoid collision with the new prelude `ne`.
Bench: check.py + cross_lang.py exit 0; compile_check.py exits 1
with one sub-ms check_ms.local_rec_capture at +26% (tolerance 25%) —
prelude-growth-related noise-band fluctuation, ratifiable per spec
§248-249 and journal Concerns.
Claude Code categorically forbids subagents from spawning other
subagents (code.claude.com/docs/en/sub-agents and the Agent SDK
subagents page). The `or.1` architecture (and `pr.1` that ran on
top of it) presumed a named-exception for `ailang-implement-
orchestrator` to dispatch implementer / spec-reviewer / quality-
reviewer / tester per task. That exception never existed at the
platform level; the `Agent` tool was silently dropped from the
orchestrator-agent's tool set at dispatch time.
Architecture revised, doc-only:
- Per-task phases (implementer → spec-compliance check → quality
check) now run as sequential role-switches in the orchestrator-
agent's own context, not as nested subagents.
- The four role-files (implementer / spec-reviewer / quality-
reviewer / tester) become phase reference files the
orchestrator-agent consults at role-switch boundaries.
- Boss-context offload preserved; fresh-per-phase context given
up (the property that drove or.1's nested-dispatch design is
not buildable in Claude Code).
Files touched:
- skills/implement/agents/ailang-implement-orchestrator.md
(frontmatter, Iron Law, Phase 2/3 rewrite, rationalisations,
red flags)
- skills/implement/SKILL.md (frontmatter, Iron Law, sub-status
vocabulary note, cross-references)
- skills/README.md (Conventions: no more named exception; agent
roster: role-files recast as phase references)
- docs/journals/INDEX.md (or.2 entry appended)
- docs/journals/2026-05-11-iter-or.2.md (new — full rationale)
- docs/roadmap.md (P1 tool-wiring item removed; resolved as
categorically-not-fixable)
- docs/WhatsNew.md (user-facing correction entry appended)
No code changes; no bench impact; CLAUDE.md untouched (no stale
references to fix there).
Per-iter journal entry for the fieldtest run plus INDEX pointer.
Roadmap absorbs four actionable findings as P2/P3 todos (split the
merged BadCrossModuleTypeRef diagnostic, workspace subdir search,
`ail check` on `.ailx` extension, `.ailx` counterpart for the
canonical happy-path JSON exhibit). The two carry-on items
(`(import prelude)` doc-gap, the working ones) stay as notes in the
fieldtest spec only. P0 Floats milestone removed — closed
2026-05-10 and no longer load-bearing context.
No bug findings, so no debug dispatch. canonical-type-names is fully
shipped.
The "tasks 1-3 of 6 landed" snapshot ages out with every
sub-commit; the plan's own checkboxes are the live source.
Roadmap entry now just carries `[~]` + a pointer to the plan.
Adds a priority-ordered, checkbox-format roadmap that the
orchestrator maintains. Three states (`[ ]` open / `[~]` in
progress / `[x]` done), four kinds (milestone / feature / todo /
idea), four priorities (P0..P3). Initial population lifts the
queued items from the JOURNAL tail.
JOURNAL's role narrows: chronological decisions log only, no
forward queue. CLAUDE.md "Roles of ..." section updated to
reflect the split.
