Brummel 76b21c00eb feat(lang): eliminate the Implicit ownership default — totality + the drop-soundness it demasks (#55)
Deletes `ParamMode::Implicit`. `ParamMode` is now `{Own, Borrow}`:
every fn-type slot on every signature carries an explicit `own` or
`borrow`, no defaulted position survives anywhere (model 0008 §2,
spec 0062). The parser rejects a bare fn-type slot; `borrow-return`
and `borrow-over-value` reject at the signature; the corpus is
migrated to minimal-ownership modes (consumed ⇒ own, read-only-heap
⇒ borrow, value ⇒ trivial-own). The documented `Implicit`-ret-mode
leak is fixed: an owned heap return now drops exactly once (live=0,
acceptance criterion 5).

This was the easy half. Removing the default ACTIVATED a family of
drop paths that `Implicit` had silently skipped — the pre-cutover
language was leaking (and in places mis-dropping) here rather than
crashing, because an Implicit scrutinee turned the drop off. Making
the modes explicit (Own) turned those paths on and exposed two
latent-bug clusters, all fixed RED-first as part of this cutover:

Drop-soundness family (four legs):
  A. lit-sub-pattern double-free — the desugar re-matched the same
     owned scrutinee in the lit fall-through; fixed by grouping
     consecutive same-ctor arms into one match (bind fields once),
     in ailang-core desugar.
  B. Cons-husk leak on non-tail arm bodies — the lit-sub-pattern
     desugar rebound the owned scrutinee via `Let $mp = xs`, which
     bumped consume_count and suppressed the existing fn-return
     partial_drop. Fixed by not rebinding a bare-Var scrutinee
     (one husk-freeing mechanism, not two).
  C. polymorphic `drop_<T>` rc_dec'd monomorphised value fields —
     the per-ADT drop fn was emitted once from the polymorphic
     TypeDef, defaulting type-var fields to ptr and rc_dec'ing
     inline Ints (segfault). Fixed with per-monomorph drop
     functions (new ailang-codegen::dropmono): the drop set is
     collected from the lowered MIR, value-type fields are skipped,
     heap fields still freed once; monomorphic-concrete ADTs keep
     their byte-identical un-suffixed drop symbol.
  D. static Str literal passed to an `(own Str)` param — the
     literal lowers to a header-less rodata constant; the callee's
     now-active rc_dec read its length field as a refcount and
     freed a static address (segfault). Fixed with the missing
     fourth StrRep::Static→Heap promotion in lower_to_mir's App arm,
     gated on Own mode (borrow args stay static, no regression).

over-strict-mode lint over-fired: it suggested `(borrow V)` for
value-typed params (which `borrow-over-value` rejects — own is the
only legal mode there) and fired on `(intrinsic)` bodies (whose
consumption the linearity walk cannot observe). Tightened to skip
both; contract 0008 updated to the narrowed firing scope.

Irreversible step — canonical-form hash reset (model 0008 §6,
acceptance criterion 6). Every signature now carries explicit modes,
so the hashable canonical JSON changed for every module. RATIFY:
the corpus-wide hash-pin reset (hash_pin, prelude_module_hash_pin,
mono_hash_stability, eq_ord_e2e, embed_export_hash_stable, the
ct4/iter*/loop_recur schema-extension pins) and the list ir_snapshot
golden were regenerated once, deliberately, as the intended one-time
consequence of removing the mode elision from the canonical form —
not a regression. Each regenerated hash verified deterministic across
two runs.

Also fixes a pre-existing latent failure surfaced by the verification
gate, unrelated to this cutover: the `every_contract_names_a_resolvable_
ratifying_test` resolver (design_index_pin) could not resolve the
" + " dual-link ratifying-test form (`uniqueness.rs + linearity.rs`)
that the #57 audit-close (dfdc65f) introduced — it shipped red on that
commit. Resolver taught the dual-link form, mirroring its sibling.

Verification: cargo test --workspace = 731 passed, 0 failed (twice,
stable); e2e 102 passed, no binary exits non-zero (corpus crash-free);
grep-clean for Implicit/fn_implicit/mode_eq across crates; every drop
fix confirmed via emitted IR + AILANG_RC_STATS balance on the head==K,
head!=K, and Nil paths. Three BLOCKEDs en route (the unsound first
husk-dec attempt, the over-strict derivation premise, the leg-B fix
direction) were each treated as a real design/spec gap and rediagnosed,
not patched over.

Supersedes #54 (return-position-only leak patch). Precondition #57
(linearity hardening) was already met. Spec docs/specs/0062, plan
docs/plans/0121.

Brummel 9d2e752f07 iter kernel-extension-mechanics.tidy: architect drift items — present-state + plugin-migration aftermath
Audit Step 3 fix path. Architect drift review at milestone close
surfaced 8 items (3 high, 4 medium, 1 low). Resolved 7 inline as
mechanical text rewrites + 2 source-rustdoc cleanups; the 1 low
(cycle-avoidance pattern documentation in design ledger) is
deferred — architect flagged it "Note, do not push" because the
pattern is implementation mechanism, not language semantics,
and is already documented in the load-bearing place
(`crates/ailang-kernel-stub/src/lib.rs //!`).

CLAUDE.md (2 sites):
  - Lead paragraph: "this file carries [...] in-tree skill system"
    → reframe to "this file carries [...] orchestrator discipline
    (the skill system itself lives in the ~/dev/skills/ plugin
    and is wired in via .claude/dev-cycle-profile.yml)".
  - Code-layout table: new row for `crates/ailang-kernel-stub/`
    documenting the zero-dep leaf design, the parse-hop location
    in `ailang-surface`, and the planned retirement at raw-buf
    landing.

design/INDEX.md (2 sites):
  - Project-ecosystem "Skills" bullet: in-tree `skills/` path +
    `skills/README.md` reference → `~/dev/skills/` plugin +
    in-tree per-project profile. Also added `docwriter` and
    `boss` to the enumerated skill list (8 in total) for
    completeness.
  - kernel-extensions row 111: added stub-retirement plan to the
    annotation so the spine names the future state, not just the
    in-tree reader of `lib.rs //!`.

design/models/0007-kernel-extensions.md (3 sites):
  - § "Migration policy" subsection: 4 bullets transitioned
    forward → present-state per honesty-rule. References to
    `loader.rs:98-108` / `workspace.rs:308-311, 467, 2655` as
    if hardcoded paths still existed → described as past state
    that has been replaced by the generic flag-filter. Codegen-
    intercept-migration bullet kept forward-looking because the
    `try_emit_primitive_instance_body` migration is *actually*
    still pending (deferred to Series milestone per spec
    § Out-of-scope).
  - § "Feature-acceptance argument": "the bounded push-only
    mutation surface — gated by the `Series` effect" — internal
    contradiction with three earlier statements that "Series
    carries no separate algebraic effect; mutation is mode-
    tracked, not effect-tracked". Re-framed to "gated by
    uniqueness mode-tracking on the owned `Series` value (not by
    an algebraic effect; see §"Coexistence" below)".
  - § "Coexistence" "Algebraic effects" bullet: "Reused
    unchanged. The `Series` effect is a new name" — same
    contradiction. Re-framed to "Not extended by Series.
    Mutation discipline lives in the uniqueness/mode system; the
    algebraic-effects set is unchanged".

Source rustdoc (2 sites):
  - `crates/ailang-core/tests/design_index_pin.rs:117` comment
    "skills/**/SKILL.md" → "any in-tree project-discipline
    document (e.g. CLAUDE.md)" — the allowlist comment now
    matches what the test actually does (no allowlist enforced
    in code; any existing path passes).
  - `crates/ailang-core/tests/design_schema_drift.rs:419`
    rustdoc: "RED until `skills/implement` mini-mode adds it"
    → "RED until the `implement` skill (mini-mode dispatch)
    adds it" — same skill, post-plugin-migration framing.

Architect items not addressed in this tidy:
  - 0007 § "The plugin contract (consolidated)" forward-intent
    reference to `try_emit_primitive_instance_body` migration —
    architect flagged as edge-case-acceptable per the explicit
    STATUS carve-out (the migration IS still pending). No
    change.
  - Cycle-avoidance pattern documentation (low): deferred per
    architect recommendation.

Tests green (664/0); workspace_pin module-count assertion picked
up from a844de3 carries through.

Brummel 832375f2ac convention: counter-prefix file naming across docs/specs/, docs/plans/, design/contracts/, design/models/
All 176 files in the four accumulating directories now use a
zero-padded 4-digit counter prefix that reflects creation order
(`NNNN-slug.md`). The counter is assigned per directory in strict
git-log creation order; ties broken alphabetically by original name.
The old `YYYY-MM-DD-` prefix on docs/specs/ and docs/plans/ files is
dropped — the date is recoverable from git log and the counter
carries the ordering.

A file's counter is stable for the life of the file: never reassigned,
never reused, never compacted. Deleted files retire their counter;
subsequent files do not fill the gap. This is the property that lets
cross-references stay literal — refs use the full filename including
the counter (`design/contracts/0007-honesty-rule.md`) so they grep
cleanly and resolve directly without a glob step.

313 cross-references updated across .md/.rs/.toml/.c/.json files
(test pins, include_str! paths, design-INDEX entries, baseline notes,
runtime C comments, inter-contract markdown links incl. bare basename
and `../models/foo.md` forms).

CLAUDE.md gets a new "File-naming convention" section spelling out
the rule and rationale. skills/brainstorm/SKILL.md and
skills/planner/SKILL.md updated so new spec/plan creation produces
counter-prefixed names from the start.

The full test suite (cargo test --workspace) passes.

Brummel 14a91f0ae5 iter boehm-retirement.1 (DONE 10/10): retire the transitional Boehm GC backend
Closes Gitea #4. Removes the Boehm-Demers-Weiser conservative GC
backend wholesale across six layers in one atomic iteration. After
this iter, `AllocStrategy` has two variants (`Rc`, `Bump`),
`--alloc=gc` is rejected at CLI parse with `unknown --alloc value`,
the libgc link arm is gone, and the design ledger describes RC
(canonical) + bump (raw-alloc bench-floor) as the only allocators.

Layer-by-layer summary:

  CLI surface — `crates/ail/src/main.rs`:
    `parse_alloc_strategy` arm `"gc" => Ok(AllocStrategy::Gc)`
    removed; error wording updated to `(expected `rc` or `bump`)`;
    clap-derive `value_parser = ["gc","bump","rc"]` allowlist on
    BOTH `Build` and `Run` subcommands DROPPED so that
    `parse_alloc_strategy` remains the sole gatekeeper for the
    unknown-value diagnostic (otherwise clap shadows the runtime
    diagnostic with `invalid value 'gc' for '--alloc'`, which would
    miss the milestone-pin's stderr substring check). The
    `default_value = "rc"` stays.

  Codegen — `crates/ailang-codegen/src/lib.rs`:
    `AllocStrategy::Gc` variant + `Default` derive removed (no
    caller of `AllocStrategy::default()` existed in the workspace,
    so the trait derivation was dead). `fn_name` (spec called it
    `runtime_alloc_fn` loosely; actual identifier is `fn_name`)
    drops the `Gc => "GC_malloc"` arm. `lower_workspace` and
    `lower_workspace_staticlib` defaults flip from `Gc` to `Rc`.
    In-source negative-complement codegen test (mod tests, lib.rs:3571ff)
    retargets from `AllocStrategy::Gc` to `AllocStrategy::Bump`
    (bump also doesn't emit per-type drop fns; the test's semantic
    "no drop fns under non-RC" is preserved).

  Link branch — `crates/ail/src/main.rs:2389ff`:
    The `match strategy { AllocStrategy::Gc => { ... cmd.arg("-lgc"); ... } }`
    arm and its libgc-link block are entirely gone. The surviving
    match exhausts on `Bump` and `Rc` (Rust's exhaustiveness check
    confirms; no `error[E0004]`). Staticlib-guard diagnostic
    rewritten to drop the "shared Boehm collector" phrasing while
    preserving the prefix `staticlib (swarm) artefact is RC-only`
    verbatim (the surviving `staticlib_bump_is_rejected` test
    depends on that substring).

  Test suite — 3 pure-differential e2e tests deleted
    (`gc_handles_recursive_list_construction`,
    `alloc_rc_produces_same_stdout_as_gc`,
    `alloc_rc_matches_gc_on_std_list_demo`); 9 RC-feature tests
    stripped of their `stdout_gc` build call and differential
    `assert_eq!(stdout_gc, stdout_rc, ...)` (absolute
    `assert_eq!(stdout_rc.trim(), "<n>")` pin retained as
    correctness oracle); `staticlib_gc_is_rejected` deleted; new
    milestone-pin `crates/ail/tests/boehm_retirement_pin.rs`
    asserts `ail build --alloc=gc` exits ≠ 0 with stderr containing
    `unknown --alloc value` and `\`gc\``; `examples/gc_stress.ail`
    fixture deleted (no remaining references).

    Implementer expansion (not in plan): `iter17a_local_box_alloca`
    (in `e2e.rs`) carried an IR-shape assertion against
    `@GC_malloc`-absence as the witness for non-escaping
    allocation. After the Task-2 codegen default flip, the witness
    shifts to `@ailang_rc_alloc`-absence in escape-targeted
    positions; assertion + doc-comment updated. Property
    protected ("no heap allocation in non-escaping contexts") is
    unchanged; only the named allocator shifts.

  Bench harness — `bench/run.sh` 9→6 column compaction
    (workload + bump(s) + rc(s) + rc/bump + bump RSS + rc RSS);
    gc-arm `bench_latency_implicit_gc` build call + harness
    invocation dropped from latency block; header comment reframed
    from "GC-overhead bench harness" to "RC-overhead bench
    harness"; "Decision 10's Boehm-retirement target (1.3x)"
    rewording to "RC-overhead-vs-bump bench-health regression gate".

    `bench/check.py:62` header-sentinel changes from
    `"gc(s)" in line` to `"bump(s)" in line`; column-count check
    at `:72` flips from `!= 9` to `!= 6`; per-workload field set
    drops `gc_s`/`gc_over_bump`/`gc_rss_kb`; `ARM_LABEL_TO_KEY`
    drops the `"implicit @ gc": "implicit_at_gc"` entry.
    `bench/baseline.json` regenerated via `--update-baseline`.

    Implementer note (planner-defect): `write_new_baseline`
    iterated over the *existing* baseline's metric list when
    emitting the regenerated file, so even after parser-level
    `gc_*` removal, the fallback emitted them back into the JSON.
    Scrubbed post-update; the cleaner fix (have
    `write_new_baseline` emit only keys present in
    `parsed_throughput[workload]`) is a follow-up if the script
    becomes load-bearing for further allocator changes.

  Design ledger — `design/models/rc-uniqueness.md` excises the
    `## Dual allocator — RC canonical, Boehm parity oracle`
    section and the `Boehm-Demers-Weiser conservative GC` choice
    block + rationale + trade-offs; the per-fn-alloca section
    generalises Boehm-specific language to allocator-agnostic;
    the memory-model section's `## Choice.` paragraph reframes the
    1.3× target from "Boehm-retirement gate" to "bench-health
    regression gate".

    `design/models/pipeline.md` drops the `--alloc=gc → links libgc`
    arm of the pipeline diagram and replaces it with
    `--alloc=bump → links bump-floor`; the accompanying prose
    rewrites accordingly.

    `design/contracts/scope-boundaries.md` rewrites the
    "Memory management via Boehm conservative GC" bullet to
    describe RC + per-fn-arena present-tense; the dead reference
    to `examples/gc_stress.ail.json` (file never existed; the
    fixture only ever had a `.ail` form, deleted by this iter) is
    dropped along with the `examples/std_list_stress.ail.json`
    reference whose purpose was Boehm-only soak testing.
    `:67`'s `@printf` / `@GC_malloc` parenthetical updated.

    `design/contracts/memory-model.md:232` drops the
    "leaks like the pre-Boehm era" phrase; the RC inc/dec
    instrumentation is wired up, so the "until then" conditional
    that referenced pre-Boehm is closed.

    `design/contracts/embedding-abi.md:42-44` rewrites the
    staticlib-guard prose to drop the `--alloc=gc` clause (gc is
    now a CLI-parser-level unknown-value, not a staticlib-guard
    rejection) and reframe the swarm-safety justification around
    `--alloc=bump` (leak-only bench instrument) rather than the
    historical Boehm collector.

  Honesty pin — `crates/ailang-core/tests/docs_honesty_pin.rs`
    inverts the polarity: the present-tense Boehm-anchor assertion
    on `pipeline.md` (`:116-117`) is deleted, and four
    absence-pins are added to `design_md_has_no_wunschdenken`
    against the Boehm-zombie strings `transitional Boehm`,
    `parity oracle`, `GC_malloc`, `libgc`. The
    `design_corpus()` already includes `rc-uniqueness.md` so no
    path-list change was needed for the new pins to scan.

    `crates/ailang-core/tests/design_index_pin.rs:166` drops the
    `"pre-Boehm"` token from the protected-exception comment list
    (the phrase no longer appears in `memory-model.md` after this
    iter, so the exception is dead).

  Runtime docs — `runtime/bump.c`, `runtime/rc.c`, `runtime/str.c`
    header comments scrubbed of Boehm/`GC_malloc`/`libgc`
    references. `bump.c`'s function signature description still
    documents `void *bump_malloc(size_t)` as the bench-floor
    allocator interface, but no longer cross-references libgc.

  Example fixtures — `examples/bench_latency_implicit.ail`,
    `bench_latency_explicit.ail`, `escape_local_demo.ail`,
    `reuse_as_demo.ail`, `rc_pin_recurse_implicit.ail` doc-comment
    headers scrubbed of `--alloc=gc` / Boehm references. The
    `.ail` surface (AST) is untouched in every case; round-trip
    invariant holds (`cargo test -p ailang-surface --test round_trip`
    green).

  Skill / agent prompts — `skills/audit/agents/ailang-bencher.md`
    rewritten to use an RC-vs-bump worked example pattern for the
    hypothesis-driven bench tutorial, replacing the recurring
    "RC vs Boehm under heap pressure" example.
    `skills/implement/agents/ailang-implementer.md` Decision-10 /
    Boehm references replaced with present-tense RC-commitment
    framing.

  IR snapshots — the 5 checked-in snapshots
    (`crates/ail/tests/snapshots/{hello,list,max3,sum,ws_main}.ll`)
    regenerated via `UPDATE_SNAPSHOTS=1 cargo test -p ail --test
    ir_snapshot`. Each previously contained
    `declare ptr @GC_malloc(i64)` and (for `list.ll`) a `call ptr
    @GC_malloc(...)` invocation; post-flip the snapshots contain
    `declare ptr @ailang_rc_alloc(i64)` plus the rc inc/dec runtime
    declarations.

Spec-vs-acceptance addendum (caught at orchestrator end-report,
absorbed here rather than in a follow-up spec edit): spec §6
acceptance criteria said "Boehm-grep returns matches ONLY in
docs_honesty_pin.rs". The plan itself prescribed historical Boehm
references in 3 additional files: (a) the new milestone-pin
`boehm_retirement_pin.rs` (must literally invoke `--alloc=gc` to
assert its rejection), (b) `embed_staticlib_alloc_guard.rs` file
doc-comment historical note ("`--alloc=gc` no longer exists as a
CLI value"), (c) `embedding-abi.md:44-45` contract historical
clause ("see the Boehm-retirement iter"). All three are
prescribed; the spec's grep wording was too narrow. The four
absence-pins in `docs_honesty_pin.rs` catch the actual zombies
(Boehm-narrative re-emerging in the design ledger), which is the
substantive intent the spec was aiming at — the four extra
documented-by-design exceptions are the cost of having an
explicit milestone-pin and contract-level historical anchors.

Net delta:
  - 32 files modified, 2 new (boehm_retirement_pin.rs + stats),
    1 deleted (gc_stress.ail);
  - workspace tests: every binary `0 failed`. Pass-count delta:
    -3 net (4 e2e tests deleted, 1 new milestone-pin test added);
  - boehm-grep state: hits only in the four by-design exceptions
    documented above;
  - `bench/check.py` exit 0 against regenerated baseline;
  - CLI must-fail fixture: `ail build --alloc=gc examples/hello.ail`
    exits non-zero with stderr containing `unknown --alloc value`
    and `\`gc\``;
  - design ledger present-tense honest (Boehm-narrative gone from
    `rc-uniqueness.md` + `pipeline.md`; the few historical
    references in `embedding-abi.md` / `boehm_retirement_pin.rs` /
    `embed_staticlib_alloc_guard.rs` are explicit milestone-pins
    or contract anchors, not silent ledger residue).

Bench measurement variance noted: closure-chain and hof-pipeline
are ±1-5% jittery between runs; one regeneration flagged 2
metrics as `regressed` before a second run returned 0. The
captured baseline is within self-comparison range. Existing
per-metric tolerances absorb the jitter.

Brummel 8ad91e7f24 iter design-ledger-formal-links.1 (DONE 5/5): clause-5 hard gate + 7 prose-ref conversions + 2 disposition-(b) homeless removals + honesty-rule positive-half (whole milestone in one iter)
Positive-half completion of the DESIGN.md -> design/ split: design/
body cross-references are now formal, file-relative Markdown links
into the durable tier (design/ or source), and a new in-tree hard
gate (design_index_pin.rs clause-5,
design_body_links_are_durable_and_resolve) walks every
design/contracts/*.md + design/models/*.md, strips fenced code
(strip_fences toggles on ```/~~~ lines so a ](  inside a fence is not
treated as a link), extracts every ](path), and asserts the target
resolves file-relative to a real file under design/-or-crates/-or-
runtime/; never docs/, never an in-file #anchor.

RED-first via identity-stubbed strip_fences (four embedded synthetic
vectors -- first one FAILS); replacing the stub with the real
toggle-on-fence impl turns the test GREEN. clause-5 composes with
clause-3 into the complete invariant the milestone establishes:
every contract cross-reference is EITHER a resolving durable
file-link OR clause-3-forbidden decision-record prose.

review-item-8 miss on my part -- a verification-arithmetic error in

(clauses 1-4 source byte-unchanged) is fully satisfied; the
implementer correctly flagged it and proceeded. The plan stands as
written; the assertion's `1` should have been `2`. Lesson noted for
future header-rewrite tasks.

Spec: docs/specs/2026-05-19-design-ledger-formal-links.md
(grounding-check PASS x3 across two corpus-grounded amendments --
clause-6 + cross-ref definition; clause-5 fence-skip + closed
convert-set enumeration).

Next: mandatory milestone-close audit (no fieldtest -- zero
authoring-surface change, reasoned exclusion).

Brummel f683f1aec8 iter design-md-rolesplit.tidy (DONE 7/7): resolve milestone-close audit drift
Gate-first TDD: widened design_index_pin.rs clause-3 to a hand-rolled
FAITHFUL Sweep-1 superset (case-sensitive digit-anchored line anchors
+ Sweep-1's ^[^/]* path-excluded date + the audit-named
decision-record phrases, case-insensitive); no regex dep; the blanket
iter-detector rejected as unworkable. Sentence-level strip of
faithfully-migrated history/decision-record prose out of 5 contract
files (the audit's 3 spot-checked + roundtrip-invariant.md +
data-model.md the exhaustive scan found) into the decision-record
journal, each replaced by its present-tense contract equivalent;
float-semantics.md stale 'see Str ABI below' -> str-abi.md;
architect_sweeps honesty sweeps re-scoped to design/contracts only
(models/ is the narrative tier) + ailang-architect.md lockstep.
Invariant: clause-3 GREEN => Sweep-1 clean in contracts/.

The prior dispatch correctly BLOCKED on a real plan defect (iso_date
lacked Sweep-1's path-exclusion, over-firing on legit
docs/specs/2026-.. citations); per the two+-defects-in-one-iteration
discipline the audit Resolution mechanism+scope were corrected
upstream in lockstep (f2cdd67) before re-dispatch, not patched a
third time.

Boss-verified independently: cargo test --workspace 646/0,
design_index_pin 4/4 (clause-3 RED->GREEN), architect_sweeps.sh exit
0 'All five sweeps clean' (acceptance criterion 9 met), acceptance
grep CLEAN, 3 docs_honesty_pin pinned runs each exactly 1 contiguous
match. Zero spec/quality re-loops. FINAL design-md-rolesplit
iteration — milestone functionally complete, audited, drift-resolved,
hard gate enforces the honesty spirit.

Brummel 176821c2e7 iter design-md-rolesplit.1 (DONE 9/9): DESIGN.md -> design/ ledger role-split
The 3020-line docs/DESIGN.md is replaced by the design/ ledger:
design/INDEX.md (sole addressable spine, typed Contracts+Models tables,
polymorphic links — prose file OR authoritative source //!), 14
design/contracts/*.md test-linked invariants + 3 source-link-only
contracts (mangling/env-construction/qualified-xref, no prose file —
code is SoT), 5 design/models/*.md whitepapers, and
docs/journals/2026-05-19-design-decision-records.md (the
relitigation-guard archive — every why/rejected/does-not-do/rollback/
empirical ### moved out at ###-granularity). Clean cut: git rm
docs/DESIGN.md, no stub.

RED-first crates/ailang-core/tests/design_index_pin.rs — the 4-clause
anti-regrowth spine (DESIGN.md-gone / every-INDEX-link-resolves /
every-contract-names-a-resolvable-ratifier /
contracts-carry-no-decision-record-prose) — demonstrably RED before,
GREEN after. Build-atomic by task ordering: design_schema_drift.rs's
include_str! (the only compile-time consumer) retargeted to
design/contracts/data-model.md BEFORE the deletion; its
## Data model/## Pipeline slicer dropped (a simplification the split
enables). 2 NoInstance diagnostics + 2 lockstep E2Es retargeted to
design/contracts/{float-semantics,typeclasses}.md. ~12 agent reading
lists + 5 SKILL bodies + CLAUDE.md + skills/README.md + ~25
code/C/.ail/spec comment xrefs retargeted; OQ7 dangling 'Iter 13b'
cite deleted (no forward target — a pointer would be fiction).
honesty-rule.md rewritten so the rule names the new home
(rationale->journals), resolving the recon-found internal
contradiction; the two docs_honesty_pin.rs:70,72 pinned phrases kept
verbatim+contiguous.

Boss-verified independently: cargo test --workspace 646 passed /
0 failed; design_index_pin 4/4; acceptance grep CLEAN of live
DESIGN.md refs (residuals = only the spec-mandated clause-4
deletion-enforcer). 2 DONE_WITH_CONCERNS routed to the mandatory
milestone-close audit: (a) str-abi.md:23 '(iter str-concat,
2026-05-13)' provenance stamp trips advisory architect_sweeps Sweep-1
— Boss-confirmed byte-identical to DESIGN.md@deeffb1:2062-2065, a
faithfully-migrated PRE-EXISTING anchor (regexes verbatim, only path
retargeted), NOT split-introduced — RATIFY-or-tidy at audit; (b) a
now stale-direction intra-prose 'see Str ABI below' cross-ref in
float-semantics.md — audit-adjudication candidate. Plan defect noted:
Task 9 Step 4's verbatim acceptance grep used a ^./ anchor not
matching the system's grep -rIn output; substance re-verified CLEAN.

Spec grounding-check PASS x2. Journals INDEX + decision-records
pointer appended (Boss-only).
