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.
Conversions (recon-and-corpus-verified closed set):
Task 2 (7 prose refs, 8 link tokens):
float-semantics.md:69 Prelude classes -> [..](typeclasses.md)
float-semantics.md:100 bare-path -> [Str ABI](str-abi.md)
embedding-abi.md:45 "Frozen value layout" -> [..](frozen-value-layout.md) (drop stale "below")
memory-model.md:44 Data model -> [..](data-model.md)
memory-model.md:105-106 Method dispatch -> [..](typeclasses.md) (drop stale "below"; the target heading lives in typeclasses.md:227, not in this file)
scope-boundaries.md:48 Str ABI -> [..](str-abi.md)
scope-boundaries.md:88 mixed split: ailang-core::desugar -> source link + Pipeline -> ../models/pipeline.md (drop stale "above")
Task 3 (2 disposition-(b) homeless removals):
pipeline.md:60-61 (see docs/PROSE_ROUNDTRIP.md) pointer removed, CLI prose preserved
authoring-surface.md:178-181 cross-tier pointer clause removed, ail merge-prose sentence preserved
Task 4: honesty-rule.md positive-half paragraph inserted between L14 and the existing L15-blank-L16; both docs_honesty_pin.rs-pinned phrases byte-identical at L14/L19 (now shifted to L19 -> L25 by the +6 lines).
Out of scope, preserved (asserted independently): every intra-file
"above/below"; embedding-abi.md:51 "frozen value layout below
specifies" (no quoted title, no (see) form); data-model.md
38/66/79/206/226 (in-fence ```jsonc schema annotations -- the inline
analog of the nominal-mention carve-out). INDEX.md and the
decision-records journal byte-unchanged; clauses 1-4 of
design_index_pin.rs source byte-unchanged (the only `-` lines in
the diff are the two-line //! header rewrite Task 1 Step 5 itself
delivers).
Boss-verified independently (not on agent report alone):
cargo test --workspace 647 passed / 0 failed
(+1 vs pre-milestone 646:
the new clause-5)
cargo test --test design_index_pin 5 / 5 passed
cargo test --test docs_honesty_pin 5 / 5 passed (additive
paragraph is pin-safe)
grep ](.../docs/.../) under design/ zero
grep ](#) under design/ zero
](-link count under design/ 8 (closed convert-set)
git diff --quiet design/INDEX.md ok
git diff --quiet decision-records ok
embedding-abi.md:48 pinned phrase byte-identical
One Concerns item: Task-5 Step-7's plan-predicted "`-` line count = 1"
was actually 2 because Task 1 Step 5 rewrote the //! header 5 -> 8
lines (removing the original L4 + L5, not just L5). Planner self-
review-item-8 miss on my part -- a verification-arithmetic error in
the plan, NOT an implementation defect. The substantive assertion
(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).
