W0: the three doctrine fences, each proven able to fire - #48
Conversation
Plan mask-membrane-valhalla-integration-v1 W0 / D-LGJ-MMV-0: turn the PR #46-corrected doctrine's three prose claims into executable fences (DoctrineFenceTest, 14 checks), because the materialization list already went stale once inside the very tree it audited -- a list without a gate is a hand-maintained artifact with extra steps. Fence 1 pins the exact per-file occurrence count of every materialization-shaped pattern in java/src/main against the doctrine's exhaustive five-site list; an unfenced site fails until the CLAUDE.md list and the pin table move together in one commit. Fence 2 asserts zero worker-topology tokens on the consumer surface -- java/src/main plus the ABI's consumer-facing files only (abi.rs + exports.rs; substrate-internal scheduling deliberately unscanned, per the ownership rule the fence enforces). Fence 3 confines backend tokens to their three define/relay homes and rejects any code line that both carries a backend token and branches. Every fence arm observed red-then-green on a planted violation before landing: unfenced Arrays.copyOf + new long[] in View.java (fence 1, both patterns), workers(int) on View (fence 2), a branch on simdBackend() (fence 3 branch half), a stray SIMD_AVX2 reference (fence 3 homes half). Anti-vacuity guards pin the corpus as real (>=20 files, >=5 backend-token code lines). Registered in AllTests including the no-native path -- source fences need no .so, same rationale as ApiSurfaceTest. Full suite 328/328 (314 prior + 14 new), zero regressions. Arc entry same-commit.

All three P2s verified real and fixed: 1+2. Whitespace evasion: fence 1's patterns are now whitespace-tolerant regexes (\bnew\s+long\s*\[ etc.) and fence 2 matches over whitespace-canonicalized lines -- `new long [4]`, `Arrays .copyOf`, `.toArray (...)` and `public View workers (int n)` are all caught, each observed red on a planted variant. A first fix attempt stripped ALL whitespace and then boundary-checked, which is self-defeating: `return new int[0]` strips to `returnnewint[0]` and the boundary the check needs is destroyed (measured -- it silently changed a pinned count). Regex with explicit \s* keeps both properties. 3. Laundering evasion: fence 3 gains a per-home carrier-line census pin (NativeRuntime 3 / Abi 4 / Layouts 4, measured). `String s = simdBackend();` followed by branching on `s` a line later evades the same-line branch check -- but the assignment itself is a new carrier line and fails the census (observed red on exactly that plant; the branch check correctly stayed silent, proving the two nets are complementary, not redundant). The stated residual -- aliasing an already-aliased value -- is beyond any source fence and documented as such. Full suite 329/329 (was 328; the census adds one check), src/main byte-identical after the disable-runs.

Update the check counts to the final state of the PR.
The record states 14 new checks and a 328/328 suite total. The PR added the backend carrier-line census after that measurement, which raised the suite to 329/329. Correct both the per-test count and the suite total so the board record matches the landed code.
Line 32 also lists a stray SIMD_AVX2 reference in View.java as a falsification case, while the class javadoc lists only three planted violations. Align the two records.
Also applies to: 40-41

…h markers The review round's own lesson made structural: every evasion finding (Codex's three, CodeRabbit's three) was the same finding — a lexical fence can be evaded by a legal spelling the pattern did not anticipate. The property that is visible in the COMPILED surface now gets the spelling-immune check: - Fence 2b (new): reflection over the compiled facade — no public method may be topology-named. Proven non-redundant: a planted workers method with its name and paren split across two lines evaded the per-line lexical fence entirely and ONLY 2b fired. - One shared codeLines() comment filter for all three fences (CodeRabbit): prose in a javadoc can no longer move a pinned materialization count or report a topology leak; block-comment interiors are skipped via a small state machine. Stay-silent plant (a comment carrying Arrays.copyOf + new long[64] + workers(8)) verified green. - Fence 3 markers match the whitespace-canonicalized line and cover ternaries and boolean operators (CodeRabbit): a pinned Layouts carrier line rewritten in place to a ternary — census unchanged — now fails the marker half; verified red-then-green. The widened set was verified to not false-positive on any of the 11 lawful carrier lines. - Arc entry corrected to the final numbers (CodeRabbit): 17 checks, suite 331/331; falsification list aligned with the javadoc. Suite 331/331.
Two paragraphs distilled from the PR #48 review round: - W0: lexical fences are tripwires, not proofs — the six evasion findings were one finding in six costumes. Where the property is visible in the compiled surface the fence gets a reflective arm (fence 2b, shipped on PR #48); where it exists only in source, lexical + census pins is the honest ceiling. - Falsification section: the standing question every future gate must answer in its own description — can it observe the violation it names, through the path a violation would take? Three-for-three this round: unmeasurable benchmarks, vacuous falsifiers, evadable patterns.
A renamed registry key in the native-independent loop now fails as a reported check, not an NPE before Checks.reportUnavailable runs (CodeRabbit, PR #48). Suite 331/331.

Use the documented 29-type anti-vacuity bound.
Line 332 accepts a compiled facade with only 5 types. The PR objective and inventory specify a minimum of 29 types. A discovery regression that loses 24 facade types can pass this fence.

Deliberate partial-accept, landed in 0eb591f: the bound is now >= 20 (was >= 5), not >= 29, and the arc entry says exactly that. Rationale: this check's job is anti-vacuity — detecting a broken classpath scan — not census. Pinning at exactly today's 29 would turn any legitimate facade refactor that removes one type into a false fence failure; exact-count discipline is fence 1's pin-table territory. >= 20 against a measured 29 still fails the failure mode this comment names (losing 24 types).

…tive bound Second CodeRabbit round on the fences, both findings verified real: - The prefix-only comment skip blanked a WHOLE line starting with a block comment, so '/* c */ new long[4];' escaped every fence. codeLines now removes comment SPANS with a small lexer that honors string/char literals — a '//' inside a URL neither starts a comment nor truncates the code after it. Plants verified: the shared-line materialization now fires; a literal-'//' line with trailing code still fires; full suite restored green. - The reflective arm's anti-vacuity bound said >= 5 while the record claimed >= 29; code now pins >= 20 against the measured 29 and the arc entry says exactly that. Suite 331/331.

…tring tripwire Fifth review round (CodeRabbit, outside-diff Majors), all three verified: - BRANCH_MARKERS gains for(/while( — a pinned carrier rewritten as 'while(accepts(simdBackend()))' consumed the diagnostic with no marker; plant verified red on a carrier-line while(). - publicFacadeTypes no longer returns a partial list on a mid-scan exception (which could satisfy the >=20 anti-vacuity bound with an incomplete facade) — it throws, same loud-failure rule as readLines. - Rust raw strings: the comment filter's quote-scan mis-lexes r#"..."# and could silently DROP trailing code — correcting this class's own earlier 'fails loud' claim, which was wrong for this case. Rather than growing a Rust lexer for two files with zero raw strings today, fence 2 now TRIPS on any raw-string opener in a scanned .rs file (plant verified red; word-boundary regex verified to not false-positive on the four r-adjacent-quote lookalikes in the real files).

strings and raw byte strings, including any valid number of hash markers. Ensure
codeLines preserves these literal contents so embedded comment delimiters do not
affect token detection, and make scanForTokens evaluate the comment-filtered
lines rather than unfiltered readLines(f) to avoid openers inside comments.

Use lexical matching for loop markers.
fenceBackendDiagnosticOnly applies contains to canonical(code), while codeLines preserves string and character literals. Therefore "while(" and identifiers such as meanwhile( can falsely mark a backend-token line as branched. Mask literals and require keyword boundaries for for( and while(.

Add Rust raw-byte-string handling and comment-aware detection.
RUST_RAW_STRING_OPENER does not match valid br"..." or br#"... "# literals. Because codeLines does not model these literals, their contents can expose // or /* as comment delimiters and hide later topology tokens. scanForTokens also checks unfiltered readLines(f), so an opener in a comment can create a false hit. Extend the opener pattern and run the check on comment-filtered lines.

What
mask-membrane-valhalla-integration-v1W0 / D-LGJ-MMV-0 — the plan's cheapest first action, justified independently by the already-merged PR #46 doctrine (so it doesn't wait on plan PR #47). Turns the doctrine's three prose claims into executable fences:DoctrineFenceTest, 14 checks, registered inAllTestsincluding the no-native path (source fences need no.so, same rationale asApiSurfaceTest).The need is measured, not hypothetical: the doctrine's materialization list went stale inside the very tree it audited (two real call sites missing when the 5+3 council re-derived it). A list without a gate is a hand-maintained artifact with extra steps.
The three fences
Arrays.copyOf,.toArray(,new long[/int[/byte[,MemorySegment.copy,ByteBuffer.allocate,Collectors.) injava/src/mainagainst the doctrine's exhaustive five-site list. A sixth site — new file or old — fails until the CLAUDE.md list AND the pin table move together in one commit. Removal of a pinned site fires too (the list must shrink deliberately).java/src/mainplus the ABI's consumer-facing files only (abi.rs+exports.rs). Substrate-internal scheduling is deliberately unscanned — that's the very ownership rule the fence enforces.NativeRuntime/Abi/Layouts), and no code line may both carry a backend token and branch.Proven able to fire (the W0 gate)
Every fence arm observed red-then-green on a planted violation before landing:
