The digest input path holds zero ResolvedType references across its four functions and 86 lines - schemaDigestOf, tagSetDesc, computeLayout, schemaDigestFor - with the extractor shown to fire on isRuleArenaType in the same execution, so the zeros are results and not silences. types.zig names schemaDigest zero times; registry.zig names ResolvedType zero times; ResolvedType exists in two files, one of them a single test helper. computeLayout derives FieldKind from the AST type node, so the chain is AST -> FieldKind -> Layout -> digest and the type checker sits beside it, not upstream. The premise came from a homonym: M1.D.47's zone is a value's memory lifetime, M1.D.45's storage is @storage(.sparse), the ECS storage mode, which registry.zig:198-200 declares OUT of the hash by ARCH-005. So it is one entry for one gesture, and 44 and 45 are a second, disjoint gesture on schemaDigestOf. The 105-site figure costed option 1 of the S4/G8 arbitration, a recursive optional payload, and not the plan's deliverable; it reproduces under no selector tried - 68/6, 90/15, 298/12, 214/2. The gesture is not single: the ambiguous variants are built at eight sites, four of them resolving a type NODE, which carries no zone and cannot. Those four sit under namedTypeToResolved, 37 call sites, most of which cannot supply one. M1.D.47 is not started and the arbitration is raised. Floor re-derived from the suite and unchanged at 2379, measured twice under a live ZLS watch build; lint conservation OK at 2379; fmt clean. Zero .zig touched.

Of 37 call sites, exactly ONE both admits an ambiguous collection type and knows the zone - lookupFieldType's .resource arm at :8178, which dispatches on the receiver and therefore holds the provenance already. THIRTEEN admit one without knowing it: twelve parameter/return sites and one let annotation. The remaining 22 are moot or derivative, and that is a measurement of the gate at :3896, where collection field types are resource-only and component/struct/event are rejected at :3917 - probed, 0 errors on resource and 1 undefined_symbol on each of the other three, which is the positive half that makes the zeros results. At the twelve parameter and return sites the zone is NOT DETERMINATE, which is stronger than unknown. The corpus holds zero collection parameters and zero collection returns against 18 let annotations, and zero in a corpus is not illegality: fn f(xs: int[]), fn g() -> int[], fn h(m: [int: int]) and fn i(s: Set<int>) all check with 0 errors. The deciding case is one program in which a single fn total(xs: int[]) takes an arena literal AND get(Bag).items at two call sites, 0 errors. There is no single answer for that site to know. So a zone variant meaning unknown re-arms the S4/G8 defect one level down, and the measurement points elsewhere: the zone is a property of a VALUE, not of a declared type. The thirteen sites describe signatures, which range over both zones by design. The open question is the SHAPE, not the blast radius, and it is architecture rather than a debt-milestone correction. One site is unmeasured and its own control says so: the cast target at :6255. types.zig:6256 must reject a non-builtin target, the probe reported 0 errors for a as int[], and its control 1 as bool - which that same line must reject - also reported 0. The probe never reached the arm, so all four readings are silences. Reported unmeasured rather than resolved on a blind instrument. Both probes appended to types.zig, run, reverted; file byte-identical at sha256 4e2e9e88 before and after each, zero ZZPROBE residue in the tree. Floor re-derived from the suite after the reverts and unchanged at 2379, which is what says the tree came back; lint conservation OK at 2379; fmt clean.

M1.D.44 - tag identity enters the schema digest. ComponentDesc gains content_digest, hashed; TagTable.contentDigest hashes the leaf count then each path by bit index, PLACING leaves at their own index rather than iterating the map, since a bit_index is a pure function of declaration order and hash order would vary build to build. Three TagSet descriptor producers were enumerated, not one: the interpreter's tagSetDesc, the codegen emission whose comment claims it mirrors the interpreter exactly, and a Tier 0 test literal. desc.fields was measured and REFUSED as the carrier - componentFields has ten readers, several on the scene-serialization path, which walk fields by kind. The false refusal is named and pinned: appending a tag inside one word is safe and is now refused, because a whole-table digest cannot tell a surviving prefix from a changed table. Accepted deliberately; an append crossing a word boundary was already refused. The test pinning the defect as an accepted adjacent case inverts to REFUSED, declared here. Counter-factual with the surviving subset named first: dropping content_digest from the hash reddens rename, reorder and append, exactly three, and the green twin stays green. M1.D.45 - both out. storage by arbitration (ARCH-005). requires by measurement taken before deciding: it never appears beside a size, alignment or offset in registry.zig, and every closure consumer is forward-looking, so a reload editing only the requires set leaves live bytes valid and meaning what they meant. Residual raised rather than filed: a newly added requisite is an invariant live entities may violate unchecked, which is not a layout problem. M1.D.38 - the E0217 emission is removed rather than relocated. It was dead by an early return fourteen lines above; relocating it above that return would fire for two undeclared symbols, where undefined_symbol is the true diagnostic. The code stays declared with no producer and its reason, and what single-module mode answers is pinned so the wrong route reddens. M1.D.39 - the set was FOUR, not the three the entry names. The three shapes are three callers of one parseCallArgList; the grammar also gives annotations an arg_list, and parseAnnotations carries its own loop with the same defect. Enumerating the function's callers gives three, the grammar production's users four. Both fixed, both independently witnessed: the test is red before the fix and red again when only the annotation break is removed. Floor re-derived from the suite 2379 -> 2385, windows 2383. The dead-tests bilateral control refused the first attempt and the declared value was moved to the measured one. Green at Debug/f32, ReleaseSafe and -Dphysics_f64=true; lint and fmt exit 0.

M1.D.48 - the four silences are closed under a control shape that fires: both negative controls fire and both INT controls stay silent in the same execution. SET, OPTIONAL, CLOSURE and a string concat of two literals all park in AsyncTask.result with zero diagnostics, so all SEVEN rule-arena forms of Value are reachable there and none was diagnosed. The string row is the one not asked for and it is the point: a concat built from a LOCAL was already refused while the identical "x" + "y" was not, though both park the same .string_run. The first was covered only because let a made it a local the sibling rule walks - coverage by accident of spelling. And the second retention point needs NO refusal, measured rather than assumed. An int? event field and an int[] event field are refused as FIELD TYPES, a struct-valued filter is refused by the filter checker, and an enum carries a discriminant. A string is the only arena form that can reach a captured filter, and captureEventFilter deep-copies exactly it. So stabilising strings alone is complete, not partial, and the fix lands at one point instead of two. The assumption is written into a test so it falls the day an optional or collection event field becomes legal. The refusal sits at .return_stmt under conc_branch == .race - where a value enters the parked result - and consults isRuleArenaType, the SAME predicate as the sibling local rule, so the two cannot drift on which forms are arena-backed. False-refusal cost measured before proposing: ZERO on the repository, the corpus holding no race construct at all. The cost is two constructed cases, both found by the green twin rejecting them: a bare string literal, not separable because a literal, a concat and a resource string are all builtin .string_; and a bare enum shorthand, which arrives .unknown and lands on the arbitrated arm instead. Both pinned in a test named for the cost. Counter-factual: disabling the refusal reddens the per-form and cost tests and leaves the green twin and the filter test green. M1.D.46 - measured first under a declaration-level negative control: all seven collisions were accepted with zero diagnostics. isReservedEngineTypeName is DERIVED from builtin_resources rather than listed, with a test walking the table, because a second list is how the two come to disagree silently. TagSet gains a named constant. E0101 is reused with a contextual message on the duplicate-test- name precedent. The green twin includes names that merely resemble reserved ones. Floor re-derived from the suite 2392, windows 2390; the control refused the first attempt. Green at Debug/f32, ReleaseSafe and -Dphysics_f64=true. Probe hygiene under the new rule: appended at end of file, retired by git checkout. The last probe also shared the file with real work, so it was cut at its marker and the removal VERIFIED on the diff - 284 insertions, zero deletions - which is the evidence a global replace could not give.

M1.D.36 - fast_paths.zig defined its own contactMargin with its own conv_k = 16 while gjk.zig exports both. The entry says five call sites; there are four plus the definition - five OCCURRENCES. The local doc said the margin "must stay gjk.zig's", an intent the code did not enforce. Dependency direction measured before importing: the narrowphase graph is acyclic and epa.zig and shapecast.zig already depend on gjk the same way. The neighbour above it is NOT in the class: boxExtent mirrors coreExtent's .box arm at a site holding raw half-extents and contains NO constant, so it has nothing to drift. Swept out deliberately rather than folded in. Verified by the determinism instrument rather than by argument: forge-determinism exits 0 with the eight witnesses byte-identical and all four discrete invariants OK; forge suite green at f32, f64 and ReleaseSafe. M1.D.37 - the sharper fault is the PATH SET, not the comparison base. The gate named bindings/generated/ and src/core/platform/ wholesale while the adapters write exactly four files. The first holds two hand-maintained .api.zig sidecars no adapter writes; the second holds nine entries of which one is generated. So a comment edit to threading.zig turned a bindgen gate red - S4/G5 of this milestone did exactly that. Narrowed to the four, and based on HEAD because "matches the COMMITTED output" is the criterion the gate's own comment states. Then the second declarant was removed: the four paths were spelled once in the two zig fmt passes and again in the diff. generated_binding_files is now the one list all three read, so a new generated file cannot be formatted and then left ungated. Two-sided witness, re-run after that refactor: with threading.zig dirty the old predicate exits 1 and the full gate now exits 0; with a generated file dirty the predicate exits 1. Both directions, or the narrowing would be indistinguishable from switching the gate off. M1.D.41 - predicate derived, no rename performed. My first arm B gave 90 subjects against the entry's 16 because it dropped the single-entry constraint: a directory entered from outside by two or more of its files is not a module. Corrected, arm B reproduces exactly under six independent graph variants. My arm A was short by exactly three, which is the whole 8-against-11 gap: build.zig:1138 is root_source_file = b.path(spec.path) inside for (test_specs), and three of the table's entries are under src/. A literal extraction cannot see a path arriving through a loop variable - and tools/weld_lint/dead_tests.zig:920 names that exact trap in the repository's own words. The entry's count is right and mine was wrong. A ninth subject, plugin_loader/desc.zig, came from applying the arm-B re-export discriminant to an arm-A declared root. The deliverable is NOT executable: src/ holds two executables, simd/bench two, and simd/tests three files with no root.zig - each group would collapse onto one reserved name. Seven subjects cannot be renamed in place; closing them is a restructure, the same verdict forge/ carries. No lint rule written either, on the M1.D.11 precedent that a completeness rule over a non-conforming set produces filling. Classification put through an adversarial audit first: five lenses, 35 verdicts, 28 survived and 7 refuted. It found two errors and both were mine. Every decisive claim re-checked by me at the source before being written. Floor unchanged at 2392 - this gate adds no test, stated because it was measured. Green: test, lint, fmt, bindgen-verify, forge-determinism. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Measurement only; no line written, and the reason is not the one the entry worries about. Who holds the locations: World.entity_locations, the single EntityId -> Location map (world.zig:167, declared "the single map" at :20). The archetype holds none, which is exactly why releaseChunkIfEmpty ANSWERS the renumbered index instead of repairing and World.reclaimChunk does the repair - the split M1.D.18 delivered. A reuse policy needs no new seam. What a move invalidates: NOTHING, because the named remedy moves no entity. removeSwap swaps the trailing entity into the freed slot, so every chunk holds a dense prefix and free space is always at the tail - never an interior hole. Partial-chunk REUSE appends at chunk.entity_count of a non-trailing chunk, which is the operation allocateSlot already performs on the trailing one. No entity moves, no Location changes, no pointer is invalidated. That is separate from COMPACTION, which the entry's title suggests and its deliverable does not name. Were it taken it would invalidate the moved entity's Location - world-owned, and reclaimChunk already repairs that class - and any live chunk pointer, comptime_query holding cur_chunk with a chunk_idx/slot cursor, already covered by the contract that structural change never runs mid-iterateArchetype. ComponentRef supports it WITHOUT CHANGE, and M1.D.18's recorded blocker is stale: it says moving an entity invalidates the chunk_ptr of every live ComponentRef and therefore touches a just-frozen contract. M1.D.21 removed chunk_ptr in S2/G1 of this same milestone, one session before that was written. Same shape as M1.D.12's deferral condition, met by work that landed elsewhere. Cost sized: only finding a partial chunk is new. A per-spawn scan is O(chunks), worst precisely in the regime the entry names where M1.D.18 measured 8200. A maintained first_partial u32 on the archetype is O(1) amortised - one u32 and maintenance at two sites. One observable changes and it is already not an invariant: under reuse a late spawn can iterate before earlier entities. The declared contract at query.zig:16 is archetype-creation order then chunk then slot, which describes the walk and survives. Spawn order equals iteration order is not that contract and is already broken today, removeSwap moving the trailing entity into the freed slot on every non-trailing removal. What is NOT measured is the benefit. M1.D.18's 6-against-2 is the full-drain case that reclamation already closes; the half-empty regime has no measurement, and the instrument is absent - ecs_hybrid_crossover.zig:149-150 records that DynamicQuery offers neither chunkAt nor chunkCount. So the obstruction is gone, the remedy is cheaper than it reads, and what is missing is the figure nobody doubted. Recommendation: build the probe first. Delivering a Tier 0 allocation policy on an unmeasured benefit is this milestone's dominant defect with the sign reversed. Floor unchanged at 2392; test and lint green. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Archetype.first_partial is a LOWER BOUND on the index of any non-full chunk, not "the first partial chunk". A bound makes each maintenance site decidable alone where an equality would make every one owe a proof: lowering is always safe, advancing must be earned, and exactly one site earns it - allocateSlot, walking past chunks it has just observed full. Four sites: the walk advances on an observation, removeSwap lowers unconditionally by @min, and the two release arms clamp. A latent defect went with it: allocateSlot returned chunks.items.len - 1 unconditionally, correct only while the trailing chunk was the sole reachable destination and a WRONG LOCATION the moment an earlier chunk can be chosen. It now returns the chosen index. No entity moves. removeSwap swaps the trailing entity into the freed slot, so a chunk's occupants are a dense prefix and its free space is always at the tail; reuse appends there, which is what the trailing path already did. Hence no location repair, no ComponentRef change, no new seam. Three witnesses in the regime reclamation does not reach - chunks stabilising above zero - each pairing the chunk count with chunks_released pinned at ZERO so the other mechanism cannot take the credit: a quarter of chunk 0 drained then refilled against a FULL trailing chunk, count stays 3; the reused entity recorded at chunk 0 with its bytes read back through that location and every displaced survivor still readable; and the bound asserted as a bound across three rounds of drain-and-refill. Counter-factual built to isolate the DECISION from the MECHANISM - the bound stays maintained and only the choice reverts to trailing-only. Predicted and measured: tests 1 and 2 redden, test 3 stays GREEN, so the first two measure the reuse and the third measures the bound. The benefit is UNMEASURED and no figure is offered. M1.D.18's 6-against-2 is the full-drain case reclamation already closes; the half-empty regime has no load measurement and the instrument is absent - DynamicQuery offers neither chunkAt nor chunkCount. What justifies the change is structural: the invalidation set is empty and the cost is one u32 and four sites. Floor 2392 -> 2395, windows 2393. Green at Debug/f32, ReleaseSafe and -Dphysics_f64=true; lint, fmt, and forge-determinism with witnesses unchanged - which matters because this is a Tier 0 allocation-policy change. S5 closes: of the fifteen entries M1.D created, NINE are closed and six leave the milestone as architecture decisions or a restructure. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
S5's subject is the fifteen entries M1.D itself created, under a rule the milestone did not have: a defect found while working closes in the same session, or it is a STOP and an arbitration, never a new number. Measured on the delivered lot (sha256 6da1d093, 648 lines): TEN of the fifteen are closed - M1.D.40 by S4, and 44, 45, 38, 39, 46, 48, 36, 37, 35 by S5 - and FIVE leave the milestone. S5 minted ZERO new entries, which is what it existed to demonstrate against a milestone that minted nine. The five that leave are not accumulated debt. M1.D.34: restricting the f64 leg changes what the matrix attests. M1.D.42: whether a directory may declare several modules. M1.D.43: a removal primitive in a registry whose ids are positional. M1.D.47: carry the zone beside the type, or split ResolvedType. Four architecture decisions. M1.D.41 is the fifth and is a restructure rather than a renaming: seven of its subjects would collapse onto one reserved name. THREE ENTRIES' OWN TEXT WAS CONTRADICTED BY THE TREE, which is this milestone's purpose applied to its own output. M1.D.47 does not overlap 44 and 45 at all - the digest input path holds zero ResolvedType references across its four functions, and the premise was a homonym, zone against @storage. M1.D.35's recorded blocker was dissolved by M1.D.21 one session earlier in the same milestone. M1.D.41's sixteen renames are unsatisfiable. The standing result: A COUNTER-MEASURE WRITTEN DOWN STOPS NOTHING UNTIL AN INSTRUMENT EXECUTES IT. dead_tests.zig:920 names the b.path(spec.path) trap in the repository's own words and the linter resolves that shape; my extraction walked into it anyway and under-counted M1.D.41 by exactly three. Tenth instance of the selector family and the first where the parade existed before the error. Beside it: one retention point measured instead of implemented, the prompt having said two - a string is the only arena form that can reach an event field, and captureEventFilter already copies it. Coverage by accident of spelling measured directly - return a + "y" refused where return "x" + "y" was not, both parking the same handle. Four errors of mine, every one caught by an instrument and none by re-reading, plus a fifth in the closing tally itself. Three blind probes in one gate whose first cause was ONE CHARACTER, wait(1s) against wait(1.0s), with both negative controls reading zero. And the latent defect in allocateSlot caught before it shipped: it returned chunks.items.len - 1 unconditionally, a wrong location the moment an earlier chunk can be chosen. Floor re-derived from the suite at every gate and never carried: 2379 -> 2395, windows 2393. Green at Debug/f32, ReleaseSafe and -Dphysics_f64=true; lint conservation OK, fmt, bindgen-verify, and forge-determinism with its eight witnesses byte-identical.

Measurement only; nothing written, because the entry's own condition was met: one part does not reserve. The world mutations of Interpreter.compile are exactly four sites - Pass A's fresh arm (registerComponentRaw, and for a resource addResource then initResourceCollections), finalizeRequires, the TagSet fresh arm and the builtin time resources' fresh arm. Passes B to E are world-read-only. Enumerated at the code, then put through a read-only adversarial audit of 37 agents, which added two side effects: getMutResource sets dirty on a fresh resource with a collection field and on no other, and finalizeRequires frees every live closure before recomputing any. OOM sweep with FailingAllocator at every index and resize_fail_index = 0, both controls firing in all three scenarios. First compile: 92 fail points, 79 change the world, and after a retry 10 resources are never seeded, 2 collection slots are null and 45 string pointers dangle. Reload adding types: 3, 2 and 23 of 60. Plain reload: 2 of 44 destroy the live @requires closures. The retry does not repair: freshness is idOf != null, so seeding is skipped for good. Everything inside the registration window reserves - each fallible call is an allocation sized by the pre-mutation world, registry and store, or a refusal decidable from it; ids are positional, so new ids and the staged closure are predictable. What does not reserve is OWNERSHIP. String defaults are immortal blocks owned by the compile's errdefer, and the committed registration writes their address into the world. A failure after the commit - passes B to E, which read the committed registry and so cannot precede it - frees what the world points at: 12 of the 12 post-registration failures dangle, and not only on exhaustion. The same split on the path that succeeds, measured: tearing the previous interpreter down after a reload zeroes the live session's collection and string pointer, and the string it was reading belonged to the old interpreter. Found by the same instrument in the same function: nine leaks from one site (rule_descs.append after compileRule), six more leak sites from the audit, one double free verified at the source, one OutOfMemory swallowed by catch continue, and one u16 offset panic decidable from the AST.

engine-zig-conventions.md §12 now has four flat prohibitions; the new one bars decision reasoning from a code file even when it passes the three criteria. CLAUDE.md carried the criteria and none of the prohibitions, so they never reached a session start; it now carries all four. The set was reproduced first: c3e6d31..f4a92da added 372 comment lines for 392 of code, 24 blocks of six or more totalling 285. Each of the 53 blocks was judged as one unit - kept whole, reduced to the shortest wording that keeps its contract, or removed whole - from read-only per-file proposals, each reviewed, applied by a script that refuses any unit holding a non-comment line. Result: 106 comment lines for the same 392 of code, and 2 blocks of six or more where there were 24; both are pre-S5 paragraphs touched only to correct a sentence S5 made false. Verified on the diff: comment -444/+106, blank -2, code 0. The adversarial pass was cut at 9 of 18 agents by a usage limit; the five unaudited files were audited by hand and the four unrefereed findings verified at the source. All four held and are fixed - two dropped wrong-fix guards (bindgen-verify against HEAD, why @requires stays out of the digest), one sentence that described the real digest as the wrong one, one grammar pointer - and the hand audit restored a fifth guard in dead_tests.zig. Comments S5's code had made false were corrected in the same pass and counted apart: the orphan rule still listed among validateTraitImpl's checks, "0 false refusals", allocateSlot filling only the trailing chunk, a drained chunk never refilled, content_digest missing from the digest's tuple, fast_paths importing support.zig only, among others. Found and not fixed, each being a code change: the tagset_component_name constant is read by nothing in interp.zig, so S5/G4's "cannot disagree" is false; vk-gen-check checks nothing (it looks up bindgen-verify before creating it; CI runs bindgen-verify directly); and etch-grammar.md contradicts itself on annotation trailing commas, §1.5 against §21.4.

Closes M1.D.43. A registry entry owns the immortal persistent blocks its default bytes point into and destroys them with itself; the interpreter and the scene cook own none. compile() registers through one transaction: every declaration, TagSet and the builtin time resources are prepared without touching the world, every refusal and every @requires closure is computed over the predicted graph, registry and store capacity is reserved, then an infallible commit adopts entries, buffers and closures. World.deinit is the one place resource payloads are released. Same instrument, same function: seven leak sites and a double free in compile(), an OutOfMemory swallowed by initArrayBlock and initMapBlock, a u16 panic past 64 KiB (now error.LayoutTooLarge), a leak in planTableDriven, and descriptor building, which now allocates in an arena the Descriptors value owns. Tests: an allocation sweep of compile() in three scenarios with both controls, the two teardown orders, the 64 KiB refusal, and a sweep of the nineteen Level-B programs.

prepareEntry copies every non-empty string default into an immortal
block the entry owns, so registerComponentRaw and the Etch compile
follow one ownership rule and a caller keeps all it passed. An empty
default is written {0,0} on every path. A collection default that names
a container is refused (CollectionDefaultNotEmpty).
Five scene tests released a resource string by hand before World.deinit
released it again: five decrefs on freed memory, now gone.
vk-gen-check depends on the bindgen-verify step itself instead of a
lookup made before that step existed. Every TagSet name in the
interpreter and the codegen derives from tagset_component_name; the
emitted source of the five tagged programs is byte-identical. The parser
cites the annotation_args production of etch-grammar.md 1.5.
Locking tests: the refusal order of a doubly-faulty reload, no default
evaluated on reload, closures that see TagSet and the builtins, every
injected name reserved, and the two raw-path ownership properties.

The loader copied a resource's raw data into the store and rewrote only the string slots the string table names, so a scene file with non-zero bytes at a string offset put a pointer nobody owns in the store, which rollback, commit and World.deinit then decref. Every string slot is now zeroed before any allocation. prepareEntry refuses a field reaching past its default bytes (FieldOutOfBounds), and both passes of the string-default copy read the caller's immutable bytes, so overlapping slots can no longer make the copies outnumber their count. A false build claim is corrected in each place it stood: vk-gen-check's old block, the "RENDER IS HELD" note on wired tests, the stub and refusal counts, the counter-proof manifest, and shaders-check, which no CI runs. forge-asm-inventory takes each cell's precision, so the f64 build is inventoried.

A type node's `data` indexes the slab of its own kind. Forty-five sites read `named_types` through it, and eleven had no guard on the kind: a resource `xs: int[]` lowered as `xs: i64` with `FieldKind.int_`, a rule parameter `xs: int[]` beside an `Entity` one was bound to the entity, and an optional node's data read far out of bounds. `AstArena.namedTypeName` returns null for every kind but `.named`, and all forty-five reads go through it, each writing its non-named branch: the codegen refuses (`UnsupportedConstruct`; `fnTypeZig` becomes fallible), the interpreter binds `.unit`, skips, or refuses (`InvalidProgram`, `RuntimeFailure`), and the guarded sites keep the branch they had. Two adjacents on the same lines. `checkRule` now refuses every non-named rule parameter with the message it already carried, instead of only an unresolvable one. The interpreter resolves `type` aliases on rule parameters as the codegen and the checker do, so `type Ent = Entity` makes the entity parameter and `type Seconds = float` binds a float. `no_raw_named_type_read` flags any `.named_types` access outside `src/etch/ast.zig`, with a bad fixture run through the real binary.

A literal that overflows its type, and a constant whose folding overflows or divides by zero, are refused when the program is checked; at run time both backends follow part1 §12.4: overflow panics in Debug and ReleaseSafe and wraps in ReleaseFast, an integer division by zero panics in every mode. The fold. `const_eval.fold` is the one folder: the checker admits a constant through it and the interpreter, the scene cook and the codegen store the value it gives, so a default the checker admits cannot fall back to zero at compile. Its arithmetic is checked in every mode. Field defaults, top-level consts and field filters fold through it (E1101 on overflow, division by zero or a non-finite float); `true or false` now folds instead of storing false, and a string concatenation default, which no backend could materialise, is refused. The literals. Every int literal fits `int` and every float and duration literal is finite, in any context, with `-9223372036854775808` judged negated. `literalTypeFits` refuses a literal outside `i32`, `u32` or `f32` (E0200), reached by all 27 of its callers, by resource instance values, params-block defaults and collection literal elements against a `let` annotation. A non-literal or negative array size or fill count is E1101 instead of an unknown type or a zero length. The run time. `value.zig` holds the mode policy: add, sub, mul, neg and `i64.min / -1` return null where overflow panics and wrap otherwise. A compound assignment reports the typed cause the binary operator does. `as i32` / `as u32` narrow, `as f32` rounds, a float whose truncation does not fit its integer target fails in every mode. A store into an `i32` / `u32` field wraps or refuses instead of an `@intCast` abort. An inclusive range to `i64` max ends, and `tick_until` converts its budget checked. The codegen routes integer `+ - * / %`, negation, compound assignment and narrowing casts through prelude helpers that choose by mode, where it emitted native operators (UB in ReleaseFast, and runtime signed `/` did not compile); float `%` lowers to `@rem`. Adjacents on the same paths: an omitted struct field takes the zero of its type, or its string or enum default, where the interpreter gave int 0; an `i32` filter accepts an int literal it falsely refused; the scene cook's `registerOne` mapped `SchemaChanged`, `FieldOutOfBounds` and `CollectionDefaultNotEmpty` to OutOfMemory through an `else`.

The interpreter refuses at compile a default whose folding fails, where it left the slot zero; the codegen emits a constant default as its folded value and a runtime literal without its separators, and a compound integer assignment through its helper. None of these had a test that tells the form from the one it replaced. Floor 2490 -> 2495 / 2493, measured: 2476/2495 passed, 19 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Item 3 of S5/G8 ter. The checker's resource collection branch validated the element type and `continue`d past every default check, so `xs: int[] = 5` passed, and the interpreter kept only what it could read: an array or map literal, element by element, dropping any element that failed to fold and ignoring every other form. The checker: a `T[]` default is an array literal, a `[K: V]` default a map literal, a `Set<T>` default `Set.new()` (stdlib §4.5), each element a constant of the declared element type (E1101 otherwise), a variant of it for an enum element (E0105), and a literal within its range; a wrong shape is E0200 for a constant and E1101 for anything else. A default on an element type already refused (E0222) is not checked a second time. The runtime: a fill default `[v; n]` materialises `n` copies where it kept one, an enum element is stored as its variant where it was dropped, a repeated map key keeps its last value as the runtime literal does where the default kept both, and any form the checker refuses is `InvalidProgram` where it gave an empty container or dropped the element. The scene cook refuses a resource with a collection field, which it wrote into a `.scene.bin` the loader always refuses. Adjacents: a scalar enum default is checked (E0105, E0200), where `m: Mode = .nope` stored the first variant; a float map key or set element is refused by the Hash bound (E0601) as it is on a `let`; a Vec3, Color or Duration element is E0222, which the element set's own text already limits to scalar POD, string and enum.

The five unchecked refusals shared one test, so a mutation of one form was hidden behind the first source that still refused. The no-cascade witness now uses a default the element check would refuse if it ran. Floor 2519 -> 2523 / 2521, measured: 2504/2523 passed, 19 skipped.

Item 7 of S5/G8 ter. A resource is no entity column, so `@requires` naming one is refused (engine-ecs-internals §3). The registry had no notion of the difference: a Zig component requiring `GameTime` resolved at the first compile, and the lock that pinned it now pins the refusal. The registry records a kind (`ComponentDesc.kind`, `.component` by default, an addition that moves no protocol version). A closure whose requisite is a resource is `RequisiteIsResource`, and a resource carrying requisites `RequiresOnResource`, both from `closeOne`, which every closure computation reaches. `World.addResource` records the kind and refuses an id a closure already requires, so a host making a type a resource after registering it is refused in either order. The interpreter declares the kind of every type it registers, builtin time resources included. Adjacents on the same paths: - The scene cook maps the two new refusals, its registry being its only `@requires` guard. - The scene loader refuses an archetype naming a resource and a resource section naming a component, which a crafted scene could do: the component was installed as a resource. - The codegen refuses `@requires` (`RequiresUnsupported`), which it dropped: its `register()` carries no requisite and resolves no closure. - A reload that changes a type's kind or its `@requires` is refused as a schema change, where it was accepted and never applied; a changed storage mode stays accepted and unmigrated, per §13. - A builtin resource name held by another type is refused, where the interpreter mapped any holder as the resource. - E0506 names a resource as one. Floor 2523 -> 2542 / 2540, measured: 2523/2542 passed, 19 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Item 4 of S5/G8 ter. `annotation_arg = expression | IDENT ":" expression | IDENT`. The parser looked for a name by consuming a leading ident and, when no `:` followed, rebuilt an expression from it by hand, which skipped every form `parsePrimary` owns: `@tag(v as f32)` was refused, `@tag(none)` and `@tag(some(1))` became an ident and a call, and `@tag(Name: 1)` was refused because a capitalised name was not looked for. The argument is now a name by two-token lookahead, and otherwise an expression. Adjacents on the same production. The annotation name is an IDENT, as §1.5 writes it: a capitalised `@Unit(...)` was parsed and accepted as a custom annotation, and no source in the tree uses one. `@storage(none)` stays E0503, a value outside the domain, and not E0504, `none` being a constant. The event and structural observer readers refuse a named argument, as the tag and requisite readers already did: `@on_event(e: Hit)` was read as `@on_event(Hit)`. Floor 2542 -> 2553 / 2551, measured: 2534/2553 passed, 19 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Item 6 of S5/G8 ter. `asset_field = [ annotation ] , IDENT , ":" ,
asset_value , [ "," ]`, in a file the user edits by hand: the reader
refused the comma between fields, the one form the ruling names, and
much of the rest of the grammar. It now takes:
- the comma between fields;
- a field annotation, parsed and not kept (the model carries none);
- comments;
- the six string escapes, decoded, with any other refused;
- triple-quoted strings with their common indentation removed;
- `_` digit separators where the lexer admits them.
It refuses what the grammar does not produce: a `+` sign, an exponent,
`1.`, a float that is not finite, an unescaped `{`, a raw newline in a
simple string, a boolean literal as a field name, and content after the
construct. The §3 schema is enforced where it was defaulted or ignored:
each fixed field and block present once and of its kind, no other
top-level field, `type` an identifier, and `uuid`, `source_hash` and
`extracted.blob` in canonical form (`SchemaViolation`, a new variant).
The writer escapes what the reader decodes, so a string holding a
quote, a backslash, a brace or a line break round-trips. The glTF
importer refuses a non-finite position or bound, which the writer had
no literal for and emitted as `nan` or `inf`.
`asset_cook` minted a fresh UUID for any intermediate the reader
refused, against §3's "Jamais régénérée"; `existingUuid` makes an
unreadable intermediate an error. Measured end to end: a second cook
keeps all three UUIDs, a corrupted intermediate fails the cook.
Two fixtures change value to satisfy the schema: the round-trip hashes
and the float test's empty `uuid` and missing blob.

The importer refuses a bound the intermediate format has no literal for; the test gives an accessor a maximum of 1e40, infinite as an f32. Floor 2573 -> 2574 / 2572, measured: 2555/2574 passed, 19 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The three nested `zig build` invocations (the triangle example, the synth_100 proof, the access counter-proof cases) ran with no option at all, so each compiled for the host's native CPU, in Debug, at f32, whatever cell ran it. They now receive `-Dtarget`, `-Dcpu`, `-Doptimize` and `-Dphysics_f64` from the outer build, and each sub-project declares `physics_f64` and passes it to its `weld` dependency. CI passes the matrix precision to the two nested steps it runs. Measured: `verify-synth-100` succeeds; `ecs-access-counterproof -Dphysics_f64=true -Dcpu=baseline` 8/8.

`dead-tests` walked the lint paths only, so a test block under `examples/` was invisible to the conservation check whether or not a step collected it. Extended, the guard names one: `examples/vertical_slice/math.zig`, one block, reached by no test root because the slice module is imported across a module boundary, which collects none of its tests. It is std-only and now has its own test root. Floor 2574 -> 2575 / 2573, measured: 2556/2575 passed, 19 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The decoder refuses a position the intermediate format has no literal for, and nothing witnessed it: under an accessor without bounds, the computed bounds are infinite too and the bound check refuses first. The test gives one vertex an x of +inf under finite accessor bounds, the only case the position check alone decides. Floor 2575 -> 2576 / 2574, measured: 2557/2576 passed, 19 skipped.

The gate never ran. In CI, `test-ppm-psnr` reported `2/3 tests passed (1 skipped)` at 9d2609c: the example runs from its own directory and writes `examples/triangle/out/smoke_test.ppm`, while the gate read `out/smoke_test.ppm` at the repository root, found nothing and skipped. The artifact upload, pointed at the same wrong path, uploaded `test-output.txt` alone (294 bytes). The gate now reads where the example writes, fails and names the file when the capture or the golden is absent, and always re-runs, since it reads a file no input of the step declares. It leaves `zig build test`, where no cell can produce the capture and it could only skip, and `dead-tests` declares it uncollected. The workflow's `exit 0` for an absent golden goes: the golden is committed. `tests/render/capture.zig` is deleted: its spawning test duplicated the smoke job's triangle run plus this gate and skipped on every cell (no triangle binary is built in `zig build test`), and its two helper tests duplicated the gate's own. Witnessed locally: no capture fails with `PpmAbsent` naming the path; a copy of the golden passes 3/3; the same copy shifted by 8 in every channel fails. Floor 2576 -> 2570 / 2568, measured: 2553/2570 passed, 17 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Six tests skip on every CI cell because their environment exists on none of them: the two Vulkan device tests of `gal_vulkan_offline` (no loader or ICD), `wayland_open_close`, `wayland_thread_safety` and the Linux path of `multi_monitor` (no compositor), and `shader_hot_reload` (no glslc). None has ever run in CI. The smoke job has weston and lavapipe; it now installs glslc too and runs `zig build test-runtime-env`, which compiles those six files a second time with `test_env.required` set. There an absent environment fails and names what is missing; in `zig build test` it stays a skip. Every skip site of the six goes through `test_env.absent`, the platform checks included, so the step cannot pass on a host that lacks what it claims to test. Witnessed on macOS: the step reports 3/8 passed, the five failures each naming its absence (a Linux host, a Win32 or Wayland host, a Vulkan host), and hot-reload passes with glslc present. Floor unchanged at 2570 / 2568, measured: 2553/2570 passed, 17 skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
`shaders-check` had four false greens and one false red, measured on the tool at 4803755: - glslc absent: "skipping", exit 0, in both modes; - a `.glsl` whose name carries no stage: skipped in silence, exit 0; - an unreadable `.glsl`: "failed to read", exit 0; - a glslc that refuses every shader: exit 0 in build mode; - the same glslc in check mode: reported as DRIFT, a verdict on the committed `.spv` drawn from a tool that never answered. And `examples/vertical_slice/shaders/` was never checked. The tool now exits with the most severe outcome it met, and only two of them are verdicts: 0 no drift, 1 drift (a `.spv` differs or is missing); 2 glslc unavailable, 3 a shader could not be read, compiled or written, a `.glsl` carries no stage, or a directory holds none. It checks both shader directories and reports on stderr, the stream `zig build` shows for a failing step (stdout is dropped there). `compile` passed the source through `/tmp/weld_shader_N.glsl`, a path with no meaning on Windows; glslc now reads it on stdin, byte-identical output measured on the six committed shaders. The hot-reload watcher and the tool derive a stage from a file name through one `Stage.ofFileName`. Witnessed through `zig build`, each naming its cause: drift 1, missing `.spv` 1, glslc absent 2 (check and build), a refusing glslc 3 (check and build), no stage 3, empty directory 3, unreadable source 3; a regeneration with glslc present rewrites the six `.spv` unchanged.

Three steps of `vertical-slice-smoke` conclude "validation clean" from the absence of any VUID in a log, and none shows that validation ran: the device loads `VK_LAYER_KHRONOS_validation` only when the loader enumerates it, and says nothing when it does not. The E6 step also discarded the demo's exit code (`|| true`), so a demo that failed to build or start left a log with no VUID and a green step. `VK_LOADER_DEBUG=layer` makes the loader log each layer it inserts; each step now fails unless its log carries the validation layer's insertion. The E6 step keeps the demo's exit code and requires its completion line, and a failure prints the log's tail. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The compile-time bench spawns `zig build-exe` on the cooked corpus with no target and no CPU, so the stub was analysed for the host's native CPU whatever `-Dcpu` built the bench, and `ZigBuildFailed` could answer for a target no cell builds. It now passes `-target` and `-mcpu` derived from `builtin.target`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
086e49c appended `-target` and `-mcpu` after the last `-M`, where the Zig CLI ignores them: a bogus CPU there compiled the stub and the bench reported GO, measured. The CLI applies both, as it applies `--dep`, to the next module declaration, so each of the three modules is now preceded by its own; a bogus CPU on `weld_core` alone now fails the bench with `unknown CPU`.

The callback recorded that it fired and ignored its SPIR-V, and a failed recompile fires it too: with glslc fed an empty source, the test stayed green, measured. It now asserts the recompile produced SPIR-V. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The seven of G8 bis, closed in the order of the ruling: the enumerations, the counter-factuals with their predictions (and the one batch run without them), the four refuted predictions of batch 6 and the defect each exposed, the tests removed or changed, and the gates. M1.D.47's perimeter measured, and the ruling's premise not holding on three axes, with their witnesses: a persistent borrow freed by a reassignment of its field, arena values escaping through `event`, observer bindings and `emit` payloads, and a type that can hide a composite. Raised as B3; M1.D.41 with M1.D.42, M1.D.34 and the S5 closure come after it and are not started. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The final cell save ran on a push or when the pull request's branch was `phase-1/debt/phase-1-debt`, a name written in the condition: S5's branch never saved, so every run restored main's cache of 2026-09-21 and recompiled all the branch had changed since. The clause is removed and nothing replaces it; a pull request restores by prefix and saves nothing. The smoke, vertical-slice and bench jobs keyed their cache on `build.zig.zon` alone. The primary key always hit, so actions/cache never saved again: all three restored an entry of 2026-09-21. Each now restores a per-commit key with a prefix fallback and saves on a push, as the cells do. CLAUDE.md stated the Release budget as 55 minutes; it is 75 since c3e6d31.

Three producers tagged `.string_persistent` over bytes that are no persistent block: the event store's copies of emitted strings, the copies a captured event filter keeps, and the world's extension names returned by `active_extensions`. A decref keyed on that tag reads a block header at `ptr - 16` that does not exist. They now carry `.string_view`, which is never counted, and every site that reads a string's bytes accepts it. `Value.eql` compared a store copy with a resource string by bytes, both carrying one tag; it still does, across the two tags, so a set holding an event's string and the resource's equal string keeps one element.

The sync `for` arms snapshot the length and re-index at each step. A `pop` in the body of a loop over an array shrinks the list under the cursor, and the next index reads past its end: a safety panic in Debug and ReleaseSafe, an out-of-bounds read in ReleaseFast. The async loops already re-check the length at each step; the two array arms now do the same and fail the body. The two map arms need no check: no map method removes an entry, so their length cannot shrink. The resource case is a checked program. The arena case is reachable only past the checker, which gives a local array no methods, and the interpreter runs such programs. Found while enumerating the holders of M1.D.47 (A). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
M1.D.47 (A), on `etch-memory-model.md` §4.4 (sha256 9c97b7d0): a read of a resource string or collection takes no reference, and every holder that keeps the value counts one. Before this, no holder counted, so a reassignment freed a block that a local, a loop, a frame or a Zig-side operand still held. - Evaluation. `evalExpr` counts each result as an arena value, whose reference returns at the arena's reset through `deferred_decrefs`. A call's result is not counted again: the callee's own evaluation counted it, and the reference transfers. - Arena containers. A struct, array, map, set or optional built from evaluation results holds the count those results took; counting again at the write would be a second count of one copy that no program can tell apart. Only two writes read a value no evaluation counted and count it themselves: the payload of a resource map lookup, and a closure's captured locals. - Locals own one reference per handle: `put` retains and releases the value it replaces, `clear` and `deinit` release, an assignment goes through `replaceHeld`, a snapshot through `put`. - An async `for` frame holds the collection it iterates, and a task holds the result it parks. - The list drains at each arena reset, at the end of each tick (async drives never reset the arena) and at teardown. Seventeen witnesses. Four run past the checker, which refuses those holdings (E0223): a task local across a suspension, a timer snapshot, an awaited assignment, and a race winner's returned string. Twenty counter-factuals, each removing one holder's count or one drain, with predictions written before the batch: each landed as predicted, on the witnesses it named and by the symptom it named (freed bytes, a leak, a crash).

Where a verified-green verdict can be read, which tree a pull request run tests, why fingerprint cannot serve as the digest, and the hole in the doc allow-list. Stopped before writing the tool. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The verdict an unchanged tree inherits lives in the ci-gate check run of a head sha, so the decision job must read it from CI and not only from a workstation. The changes job gets checks: read and asks for the previous head's ci-gate with its token and without one; a control job with contents: read only asks the same. Temporary: it goes with the tool. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
M1.D.16. The changes job no longer diffs the pull request against main and classifies paths; it asks tools/ci_verdict whether the code of this tree is identical to a tree already verified green, and the YAML acts on the answer. The digest is git's own addressing, (mode, type, blob sha, path) over the tracked files, minus briefs/ and CLAUDE.md, read from the objects. A head inherits the ci-gate verdict of a commit only if the base is an ancestor of that commit and of the head, the tested tree is the head tree, and the two digests are equal. The candidates are the pull request's commits, newest first, then the base, which main's own run verified. A red or still-running verdict on the same code decides a run; so does any doubt. A push always runs. The verdict is read from the ci-gate check run of the GitHub Actions app through curl. A test of the tool scans every tracked Zig file, manifest and workflow and reddens when one reads an excluded path; it saw the two old exclusion lists this replaces. tests/etch/ebnf_examples.md, which the old *.md pattern exempted while a test embeds it, is in the digest. bench.yml consumes the same tool against a new bench-gate job, and loses its paths-ignore list.

Squash message
S5's subject is the fifteen entries M1.D itself created, under a rule the
milestone did not have: a defect found while working closes in the same session,
or it is a STOP and an arbitration, never a new number. Measured on the delivered
lot (sha256 6da1d093, 648 lines): TEN of the fifteen are closed - M1.D.40 by S4,
and 44, 45, 38, 39, 46, 48, 36, 37, 35 by S5 - and FIVE leave the milestone.
S5 minted ZERO new entries, which is what it existed to demonstrate against a
milestone that minted nine.
The five that leave are not accumulated debt. M1.D.34: restricting the f64 leg
changes what the matrix attests. M1.D.42: whether a directory may declare several
modules. M1.D.43: a removal primitive in a registry whose ids are positional.
M1.D.47: carry the zone beside the type, or split ResolvedType. Four architecture
decisions. M1.D.41 is the fifth and is a restructure rather than a renaming: seven
of its subjects would collapse onto one reserved name.
THREE ENTRIES' OWN TEXT WAS CONTRADICTED BY THE TREE, which is this milestone's
purpose applied to its own output. M1.D.47 does not overlap 44 and 45 at all - the
digest input path holds zero ResolvedType references across its four functions,
and the premise was a homonym, zone against @storage. M1.D.35's recorded blocker
was dissolved by M1.D.21 one session earlier in the same milestone. M1.D.41's
sixteen renames are unsatisfiable.
The standing result: A COUNTER-MEASURE WRITTEN DOWN STOPS NOTHING UNTIL AN
INSTRUMENT EXECUTES IT. dead_tests.zig:920 names the b.path(spec.path) trap in the
repository's own words and the linter resolves that shape; my extraction walked
into it anyway and under-counted M1.D.41 by exactly three. Tenth instance of the
selector family and the first where the parade existed before the error.
Beside it: one retention point measured instead of implemented, the prompt having
said two - a string is the only arena form that can reach an event field, and
captureEventFilter already copies it. Coverage by accident of spelling measured
directly - return a + "y" refused where return "x" + "y" was not, both parking the
same handle. Four errors of mine, every one caught by an instrument and none by
re-reading, plus a fifth in the closing tally itself. Three blind probes in one
gate whose first cause was ONE CHARACTER, wait(1s) against wait(1.0s), with both
negative controls reading zero. And the latent defect in allocateSlot caught
before it shipped: it returned chunks.items.len - 1 unconditionally, a wrong
location the moment an earlier chunk can be chosen.
Floor re-derived from the suite at every gate and never carried: 2379 -> 2395,
windows 2393. Green at Debug/f32, ReleaseSafe and -Dphysics_f64=true; lint
conservation OK, fmt, bindgen-verify, and forge-determinism with its eight
witnesses byte-identical.

What S5 closes
Fifteen entries M1.D itself created. TEN closed, five leave the milestone.

None is accumulated debt.
M1.D.34— restricting the f64 leg changes what the matrix attests.M1.D.42— whether a directory may declare several modules.M1.D.43— a removal primitive in a registry whose ids are positional.M1.D.47— carry the zone beside the type, or splitResolvedType.Four architecture decisions. And one restructure:
M1.D.41— not a renaming:src/holds two executables,simd/bench/two,simd/tests/three, so seven subjects would collapse onto one reserved name.And the shape of it
M1.D produced fifteen entries while emptying its own table. Ten are closed by the session that existed for that, and S5 minted zero new ones — the rule it ran under being that a defect found while working closes in the same session, or it is a STOP and an arbitration, never a new number. It stopped five times.
Three of those entries had their own text contradicted by the tree, which is this milestone's purpose applied to its own output.
