`Expr::LocalSet`'s arm lowers its initialiser and then discharges every obligation that binding a value to a local carries: the alias addref, closure captures and boxed cells, the canonical-i32 slot, the plain-slot store with its shadow-frame and i32 mirrors, module globals, the arena owner, buffer views and int facts. All of it depends on nothing but `(ctx, id, v, value)`. Move it, VERBATIM, into `bind_lowered_value_to_local`; `LocalSet` becomes `lower_expr` plus a call to it. The caller this exists for is a read region's fast arm (#10884, the slice after #10946), which holds a value it loaded out of an object slot rather than one `lower_expr` produced. Today such a caller can only emit a bare store and remember each obligation separately, and a skipped addref there is a use-after-free that no fixture reliably catches. #10946 handles that by DECLINING every binding whose obligations are not "a bare store", which is exactly why it cannot reach a binding whose initialiser refines its type. The guarantee wanted is structural rather than attentive: there is one place where a value becomes a local, and both arms of a region go through it. Nothing else changes, and both halves of that are checked rather than asserted: * VERBATIM. Applying exactly `value.as_ref()`->`value`, `*id`->`id`, `.get(id)`->`.get(&id)` (and `contains`/`contains_key`), `&v`->`v` and `source_id != id`->`*source_id != id` to upstream/main's tail yields the new function's 107-line body character for character. * IDENTICAL EMISSION. `PERRY_SAVE_LL` over 41 programs from `test-files/`, compiled by a compiler built from upstream/main and by this branch: 41 identical, 0 differ, 0 produced no IR. `cargo test --release -p perry-codegen -- --test-threads=1`: 2170 passed, 0 failed. fmt clean; no new clippy warning in the touched file.
…t too #10826 removed the compare from the shape-gated MRU hit, on the proof that every successful delete moves the receiver's ShapeId, so an exact-id match proves the slot it names is live. The way path kept its copy, with the emitter's own note that removing it was "a separate, measured change". This is that change. A way pair needs no argument of its own. `pic_prime_get` is the ONLY writer of a way, and the only values it ever writes into one are `prev_tok` / `prev_slot` -- the pair that was sitting in the MRU entry. Every `(token, slot)` a way holds is therefore an MRU pair that aged out; the token it is compared against is the same receiver ShapeId word the MRU compare reads; and ShapeIds are never reused. Whatever makes the MRU pair safe to load without a hole check makes the way pair safe -- the entry did not become weaker by moving one word over. The two ways in which a way pair differs both narrow it: an overflow-encoded slot is refused entry to a way at all, and a way is consulted only after the MRU entry has missed. `pic.way.live` goes with the compare: the load block has nothing left to decide, so it ends in the load and a branch to the merge. The two codegen tests that pinned the compare as PRESENT now pin it as absent, and the block-set test drops `pic.way.live`.
test_parity_delete_shape_transition.ts covered deletes observed through monomorphic sites only. Section 9 makes five shapes resident in ONE site's cache -- the MRU entry plus the four ways -- then deletes the read key off two of the receivers, one with the key on its prototype and one without, reads back through the same site, and re-adds. It passes on both arms of this branch, as it must: it guards the way path's JS-visible behaviour, it is not a discriminator for the compare removal. The discriminator is the pair of codegen tests, which fail on the base emitter.
`runtime_symbols()` matched `extern "C" fn <literal js_name>`, so every symbol
defined THROUGH a macro was invisible -- the macro body reads `pub extern "C"
fn $name`. 56 exported `js_*` symbols were missing, and `--audit-poll-capable`
reported two of them as naming nothing:
js_string_replace_regex_fn
js_string_replace_all_regex_fn
Both exist: declared by codegen at `runtime_decls/strings_part2.rs:404-405`,
defined by `regex_value!` at `regex/perex_replace_compat.rs:89-90`. They are
`String.prototype.replace(re, fn)` -- a USER JS CALLBACK, so unambiguous poll
points. The remedy the report invited, deleting the stale-looking entries,
would have dropped coverage of a real poll point and turned the audit green;
the audit's own error text warns against precisely that, but the scanner gave
no way to tell "stale" from "invisible".
Second under-count in that one function. #8207 widened it for `-unwind` and hid
18 symbols including `js_throw`. Same class, same direction: silent, always
toward green.
Fix: also collect `js_*` names passed to an ITEM-POSITION macro invocation.
Item position is the discriminator that works -- a macro that defines an export
sits at column 0, while `assert_eq!(js_thread, ..)` in a function body is
indented and defines nothing. All three invocation shapes in the tree are
covered.
The body extractor had the same blindness one layer down, and more quietly: a
macro-generated symbol has no per-symbol body, so `--audit-poll-reach` saw it
calling nothing and could never report it reaching a poll point. Each
`macro_rules!` body is now attributed to the symbols it generates.
Over-attribution is possible and deliberate: it can add an edge a specific arm
would not have, which makes that audit stricter, never blinder.
`--verify-symbols ARCHIVE...` is the guard, wired into gc-root-dominance.yml
where the archives already exist. It cross-checks the scanner against `nm -gj`.
nm is a LOWER bound -- one target's archive omits the other targets' cfgs -- so
the assertion is `nm <= scanner`. Measured: nm defines 3814, scanner sees 3932
(56 macro-generated); the only names beyond nm are the 17
`js_wasm_export_call_*` shims, real and absent from a non-wasm build.
Sabotage-tested by restoring the old narrow scanner: 39 invisible symbols
reported, including both of the above, exit 2.
One entry WAS stale and is deleted: `js_ratelimit_new_from_options`, whose
crate went with the npm-binding strip -- no definition, no codegen declaration,
nothing in nm. Telling that apart from the two above is the distinction the
scanner could not make before.
Verified: --self-test, --audit-alloc-re, --audit-poll-capable,
--audit-poll-reach and --audit-immovable-sources all exit 0; the 56 recovered
symbols all have bodies now (previously none did) and 6 have intra-runtime call
edges.
`--verify-symbols` catches any shape the scanner's regex misses, but it needs built archives, so it lives in `gc-root-dominance.yml` -- label-gated on PRs, and otherwise only on scheduled `main` runs. That is precisely the omission #8821 moved the poll-reach audit into `lint` to prevent: a build-free audit living only in the label-gated workflow "is skipped on every PR and speaks only on scheduled `main` runs, after the fact". `--audit-macro-item-position` is the build-free half. It enforces the heuristic's PRECONDITION rather than its result: a macro invocation naming a `js_*` symbol at an indent -- an export macro wrapped in an inline `mod`, the one shape that breaks column-0 recognition -- fails with the file, the line, the symbol and the three possible remedies. Sub-second, no corpus, no build, so it runs in `lint`, which IS a required context. Sabotage-tested by planting `mod nested_shim { regex_value!(js_string_replace_regex_fn, false); }`: reported at perex_replace_compat.rs:90, exit 2, and the macro-generated count drops 56 -> 55 in the same run. `_NON_DEFINING_MACROS` keeps the assertion and formatting macros out, which is what makes `assert_eq!(js_thread, PRIMARY_AGENT)` in agent_dispatch_tests.rs a non-hit rather than an exemption.
Two follow-ups on `--audit-macro-item-position`, both about the allowlist rather than the scan. `_NON_DEFINING_MACROS` is an allowlist, so its failure direction is the whole point: an unknown macro reads as DEFINING and fails, which makes a new assert-like macro a loud false positive somebody fixes in one line instead of a silent miss. Said so in a comment, because the obvious tidy-up later is to invert it into a list of known-defining macros -- which would reintroduce exactly the bug this file has now shipped twice. An allowlist can also go vacuous the same way a scanner can, so `--self-test` gains two arms. The first empties the allowlist and requires the scan to then report something: it suppresses exactly ONE real occurrence today, `assert_eq!(js_thread, PRIMARY_AGENT)` at agent_dispatch_tests.rs:48, so a rename of that test would otherwise leave the arm passing while suppressing nothing. The second asserts an indented invocation of an UNLISTED macro is recognised as a hit. Verified both are non-vacuous rather than assuming a green self-test: emptied, the scan reports 1 hit and names that line; with the real allowlist, 0.
Written and run before any production edit. Node 26.5.1 passes all six cases; installed Perry 0.5.1520 reports the two expected failures (6 vs 103, 10 vs 107), with exactly one conversion and a mutated late slot. Four right-associated/snapshot controls pass. The fixture asserts all six cases executed. The assigned base already carries the production fix from #10921.
…ng that was already paid for (#10868 step 2.5 stage 1a) The object kind was encoded as ONE flag bit (RECORD_FLAG_KIND_CLASS), so it could represent exactly two values, and facts_key folded it as a bool. A third variant added on that footing would have read back as Ordinary from object_kind() — and since facts_match compares the full enum, that is a wrong identity match, not a hash collision. Replace flags: u8 + _pad: [u8; 3] with one flags_and_kind: u32 — the same four bytes in the same place — holding the flag byte in bits 0-7 and a 2-bit kind in bits 8-9. The record stays 32 bytes and 8-aligned, both const assertions hold unchanged, and the slab geometry is untouched: the kind lives in padding that was already allocated. facts_key now folds the kind discriminant rather than == Class, so Ordinary and Dictionary no longer share a hash contribution. Every existing consumer guards with == Ordinary or != Ordinary rather than a match, so a Dictionary shape declines all seven fast-path sites with no further edit — including ic_miss.rs is_regular and delete_rest.rs stable_candidate. That is the point: a keyless shape otherwise reads as this receiver has no own properties to a long tail of consumers, two of whose members are correct only by accident, and a set with accidental membership cannot be secured by enumerating it. Tests (single-threaded): record geometry and the O(1) probe property asserted together, so a future field cannot quietly make the kind cost memory; every kind reaches the fold distinctly; a record round-trips all three kinds beside its flags. Must-fail verified: restoring the bool fold reddens every_object_kind_reaches_the_facts_fold with Ordinary and Dictionary collide and leaves the round-trip test green.
`aeaa912c1d` bumped rustls to 0.23.45 for RUSTSEC-2026-0285. A branch that CONTAINS that commit resolves rustls to 0.23.44, because a merge regenerated `Cargo.lock`. `Cargo.lock` appears in `.github/workflows` only as a cache key, so an input that determines every built artifact is rewritten by tooling during merges and no test can fail when it moves the wrong way. PER-CONSUMER, NOT PER-PACKAGE-MAX. A dependency is downgraded only when a consumer present in BOTH locks resolves it lower. `max(after) >= max(before)` cannot distinguish a downgrade from a REMOVAL: on the real pair it reported three findings of which two were false (crc 3.4.0 and crc-catalog 2.5.0 left with the deleted sqlx-* crates; the one shared consumer, swc_bundler, resolves crc@2.1.0 on BOTH sides), and both would have blocked a correct merge. Edges are keyed on (consumer NAME, consumer VERSION) — name alone recreates that conflation one level down, since main carries crc@2.1.0 AND crc@3.4.0 wanting different crc-catalogs. TWO FALSE NEGATIVES FIXED FROM REVIEW. Both are the direction that matters: a gate that misses a downgrade is worse than no gate, because it is believed. 1. THE DENOMINATOR COUNTED THE WRONG POPULATION. It reported edges parsed from the BEFORE lock. If the after-lock parses to none, those edges are still there, no downgrade is found, and the run reports a large reassuring number for having compared nothing — the exact confusion the denominator was added to make impossible, inside the fix for it. It now counts COMPARISONS MADE, and zero comparisons is a hard failure. 2. THE BUMPED-CONSUMER FALLBACK DID NOT RUN ON A PARTIAL CHANGE. Gating it on "the consumer's version sets are disjoint" means app@1.0 + app@2.0 before and app@2.0 + app@3.0 after intersects at 2.0, so the consumer is skipped entirely and the 1.0 -> 3.0 move is compared by neither rule. It is now per VERSION. The trap inside that fix: a vanished consumer version is not always a bump. crc@3.4.0 did not become anything — it left, taking crc-catalog@2.5.0 with it. So the fallback requires a strictly HIGHER version of the same consumer to exist in the new lock; without one it is a drop, and drops are reported, never failed. Verified on the real locks: main -> the branch flags rustls and nothing else; main -> main passes across 3,327 compared edges, matching the reference implementation's count. Also corrected against that reference: its flat `re.split(r"[.+-]", v)` key sorts a PRE-RELEASE ABOVE its release, because the extra components make it the longer tuple. The real locks cannot reveal it — their pre-release findings are downgrades on the numeric part alone. Semver says `1.2.3-rc.1 < 1.2.3`, and shipping a release candidate over a release is the backwards move this refuses. Self-test, 12 cases, run by `lint`, and it asserts the denominator as well as the verdict: a case that compared nothing fails rather than passing, because its verdict would be vacuous. It leads with the shapes the REAL DATA contains — a shared consumer resolving lower (must fire), a higher version whose every consumer is absent (must not fire), a partially overlapping consumer (must fire), an after-lock with no edges (must fail) — because the twelve greens that preceded the review covered the shapes the predicate was designed for, not the population the data holds. Three times today the same way: the population was wrong, not the polarity. NOT WIRED AS A PR LINT. `--vs <merge-base>` is for merge tooling to call; only the self-test runs here, and wiring is merge-agent's (#10980).

In `@changelog.d/10974-button-symbol-point-size.md`:
- Line 3: Update the changelog entry’s issue reference from `#10951` to `#10974`,
leaving the surrounding description unchanged.
In `@crates/perry-codegen-wasm/src/emit/ui_method_map.rs`:
- Line 143: Add the missing perry_ui_button_set_font_family bridge alongside the
existing button style bridges, applying the family value to the button element’s
fontFamily style, and include it in the __perryUiDispatch registration so both
JS fallback and memory dispatch can resolve buttonSetFontFamily.
In `@crates/perry-runtime/src/json_tape.rs`:
- Line 314: Update the deep-parser malformed-literal branches in
malformed_offset (including the true, false, and null cases) to compare the
input against the expected literal and report the offset of its first
mismatching byte, matching DirectParser::invalid_literal rather than the literal
start. Add regression coverage for deeply nested malformed literals such as trux
and equivalent mismatches for false and null.
In `@scripts/gc_root_dominance_check.py`:
- Around line 843-846: Update nm_exported_symbols to retain the subprocess
result and check its returncode for each archive. Raise the existing MalformedIR
with the archive name, exit status, and bounded stderr when nm fails; only
update symbols from stdout on successful execution.
- Around line 768-770: Update the depth calculation in _macro_defined_symbols to
use literal-aware non-code stripping rather than removing only // comments,
preventing delimiters inside strings, raw strings, byte strings, and character
literals from affecting macro depth. Extend _strip_noncode or the scanner to
cover these Rust literal forms, then preserve the existing delimiter counting
behavior for actual code.
In `@scripts/lock_no_downgrade.py`:
- Around line 104-105: Preserve Cargo source qualifiers as part of package
identity throughout parse_lock, resolve, registry filtering, edge construction,
and comparison logic. Use (name, version, source) consistently so same-name
packages from different sources are not merged or treated as
upgrades/downgrades; add self-tests covering both the hidden-downgrade and
false-downgrade cases.

Add the missing WASM button font-family bridge.
buttonSetFontFamily emits perry_ui_button_set_font_family, but the WASM runtime does not define or register that function. The JS fallback therefore calls an undefined bridge, while the memory dispatcher cannot find a registered function. Add the bridge and register it in __perryUiDispatch.

Report the first mismatching literal byte.
For deep JSON, malformed_offset uses these branches after the direct parser exceeds its nesting bound. Each branch reports pos at the literal start. DirectParser::invalid_literal reports the first mismatching byte.
A deeply nested payload ending in trux reports the t position instead of the x position. Compute the first mismatch for true, false, and null. Add deep malformed-literal regression cases.

Strip literals before the macro depth walk.
_macro_defined_symbols counts delimiters after removing only // comments. A delimiter in an ordinary, raw, byte, or character literal can keep the depth positive after the macro invocation ends. The scan can then collect unrelated indented js_* arguments as phantom symbols. The audits may therefore miss missing runtime coverage.
Reuse _strip_noncode for the depth calculation:
Suggested fix
depth = 0
for j in range(i, len(lines)):
- stripped = re.sub(r'//.*', '', lines[j])
+ stripped = _strip_noncode(lines[j])
depth += (stripped.count('(') + stripped.count('{')
- stripped.count(')') - stripped.count('}'))_strip_noncode does not handle character literals or raw strings. Extend it, or otherwise make the depth scanner literal-aware, before relying on it for all Rust macro inputs.

Report nm failures instead of treating them as empty archives.
nm_exported_symbols ignores subprocess.run(...).returncode. If nm cannot read an archive, the empty stdout contributes no symbols. verify_symbols_against_archives then reports the generic runtime-build error instead of the archive-read failure.
The configured workflow runs on macos-14, so the ELF-specific failure is not established for that workflow.

Preserve source-qualified Cargo package identities.
parse_lock drops each package source, and resolve drops source suffixes from dependency IDs. edges then merges packages with the same name and version and keeps only the maximum dependency version. Cargo uses the source to distinguish packages with identical names and versions.
A downgrade for one source can therefore be hidden by a higher version from another source. A source change can also produce a false downgrade. Use (name, version, source) as the package identity throughout parsing, resolution, registry filtering, edge keys, and comparisons. Add self-tests for same-name, same-version packages from different sources that cover both outcomes.
