Walks the implementer from a fresh harness/ Cargo project to a green
test sweep across strip_locations (5 unit + 5 integration on real
captured stderr), verify_references (4 reference solutions run
through the live ail+clang pipeline locally), mock_full_run (eight
canned-cohort-task pairs end-to-end), and budget_abort (tiny budget
exhaustion). Six modules: strip_locations, pipeline, ionos
(reqwest blocking + retry per spec §Error handling), mock, scoring,
tasks. Captures five real stderr samples (recon-collected) as
fixtures; strip_locations regex calibrated to the actual diagnostic
shape (handles `at byte N`, anyhow `Caused by:` chains).
Workspace-table and .gitignore included in Task 1 from the outset
(learned from cma.1 surfaced concerns; not repeated as
post-hoc journal items). Out-of-workspace pattern matches render/
verbatim. AIL_BIN env var with PATH fallback for `ail` resolution;
clang preflight check added since `ail build` shells to clang.
Two explicit deferrals to implementer named in the plan:
ParamMode names (lifted from cma.1) and prelude function symbols
(from crates/ailang-check/src/builtins.rs); both stable from cma.1
authoring, no re-derivation needed.
Walks the implementer from a fresh directory to a green test sweep
(splitter_unit, spec_completeness, example_roundtrip, token_balance)
plus two checked-in rendered/*.md files. Visitor borrowed verbatim
from schema_coverage; master/examples authored fresh as a curated 13-
fixture set (one per AST variant cluster); master/spec.md authored in
13 sections with form-only blocks balanced by the ±5% gate.
Open authoring deferrals to the implementer (named at the planner
level, intentional): exact ParamMode enum names and the canonical
prelude function names — both retrieved from current source by
reading ailang-core/src/ast.rs and the prelude module at authoring
time, rather than pinned in the plan against a possibly-stale recall.
Plan for the corrected iter 23.4: restructure mono.rs into a single
specialiser for every Type::Forall-quantified Def::Fn (class methods
+ polymorphic free fns) in one fixpoint pass, and remove the codegen-
time specialiser (lower_polymorphic_call + module_polymorphic_fns +
mono_queue) entirely.
11 tasks, 4-step TDD template per task (write-failing-test →
verify-fail → write-impl → verify-pass), no per-task commit step
under the new disc.1 discipline.
Parent spec: docs/specs/2026-05-11-23-eq-ord-prelude.md (re-grounded
2026-05-11 against main HEAD 51da9fa, PASS, 10 load-bearing
assumptions verified).
Open commitments resolved:
- N-ary mono-symbol naming: spec default <name>__<t1>__<t2>__...
- Target-collector: extension of existing collect_mono_targets
(lockstep with collect_residuals_ordered)
- Original poly Def::Fn retention: kept parallel to Def::Class/
Def::Instance
Float-NoInstance diagnostic wording remains deferred to iter 23.5.
The 23.4 mono-unification plan (ea0285b) assumed prep1 + prep2 +
prep3 were on main. They never were — they sit only on iter/23.4.
Spec component table was factually wrong. Plan Task 10 (revert prep
commits) was impossible on main. Discarding the plan; the spec is
next revised against the actual main state.
