Caught by running the contracts rather than by inspection:
- package-release.sh built its archives from an ARCHIVE_MEMBERS array, which
only ever existed to append a UI pack conditionally. With a fixed four-file
inventory the array hides the member list from the very contract that is
supposed to pin it, so the members go back inline on the archive call.
- test_windows_bundle_contract.sh asserted the pypi wrapper exposes
_windows_binary_ready(). That function became _runtime_set_ready() when the
wrapper locks were reworked; the contract now asserts the current API, since
the property it guards is "resolves the single Windows binary", not a name.
- test_smoke_fixture_contract.sh required smoke-local.sh to emit both a
variant-suffixed archive and a standard alias. There is one archive name now,
so it asserts that instead -- and that ${SUFFIX} is gone entirely, so the
alias machinery cannot quietly return.
Verified on the built artifact: the binary runs, carries 9 shebangs, 1
node:child_process and 14 hook-augment references (the deliberately inverted
property), and contains zero references to cbm-integrations.json, CBMUIPK or
--verify-runtime-assets.
Contract status on macOS: build_dir_safety, makefile_ts_runtime_dependencies,
parallel_harness, security_fuzz_harness, security_strings_allowlist,
soak_daemon_recovery, spawn_no_window, ui_dev_proxy_security, venue_parity,
vm_worktree_manifest, windows_bundle, smoke_fixture, vt_gate_policy and
vt_release_notes all pass. hook_conflict_notice, parent_watchdog and
worker_error_response fail for the documented environmental reasons (TEST_SEAMS
build seam, and the developer's own installed daemon holding the version
cohort), not from this change.

Completes the collapse to a single shipped composition and replaces the
zero-tolerance VirusTotal gate with a narrow, disclosed policy.
Packaging and installers
- package-release.sh loses --variant; archives are codebase-memory-mcp-<os>-<arch>
with exactly four members. install.sh/install.ps1 lose --ui/--standard.
- The extractor drops CBMUIPK pack parsing and --archive-scope; its scan-set and
association manifests (which the gate depends on) are unchanged otherwise.
- npm/PyPI/Go wrappers: the runtime "set" is one file again. The Windows lock
and race fixes from #1495/#1496 are kept; only multi-file set membership goes.
This also fixes `pip install` on Windows, which rejected the fifth archive
member against a hardcoded four-name allowlist.
- The wrappers' post-download probe moves from --verify-runtime-assets (removed)
to --version, which proves the same thing: the binary executes.
VirusTotal gate
- Exactly ONE detection is tolerated, and only when the engine is Microsoft AND
the label ends in `!ml`. Two or more engines, any non-`!ml` label, any other
vendor, any suspicious verdict and every infrastructure error still block.
- A tolerated object prints TOLERATED:, never OK:, and its counts are recorded
in vt-results.tsv exactly as a blocked one would be.
- append-vt-notes.sh mirrors the policy. It previously hard-failed on any
malicious count, so loosening only the gate would have passed the scan and
then died at note publication. The notes now DISCLOSE a tolerated detection
and link to SECURITY.md rather than claiming "0 malicious" for everything.
Rationale for the tolerance is in the gate itself: the verdict is not a property
of our bytes. It inverts across architectures and link modes, moves between
sibling artifacts of one build, and lands in different variant buckets for the
same source. The same `!ml` family hits llama.cpp, GitHub's own `gh`, Microsoft's
own Go toolchain and Anthropic's Claude installer.
The zero-tolerance contract becomes test_vt_gate_policy_contract.sh, asserting
the full matrix: 1x Microsoft !ml passes and reports TOLERATED; a Microsoft
signature label, a non-Microsoft engine, two engines, a suspicious verdict and
every malformed-response case still block. Its tripwire is narrowed to the
reverted endpoint-verification mechanism rather than the words "false positive",
so it no longer fires on a deliberate in-gate policy branch.

Externalizing the integration templates (#1492/#1493) and the UI bundle
(#1501/#1503) was done to reduce the Microsoft `Wacatac.B!ml` surface. It did
not work: across dry runs the flagged artifact count stayed at ~3 and the
detections merely moved between artifacts.
Dissection of run 31286803592 shows there is no structural cause to fix. The
verdicts split across every axis at once — linux-amd64 (dynamic) flagged while
linux-amd64-portable (static) is clean, but linux-arm64 (dynamic) clean while
linux-arm64-portable (static) is flagged. The two macOS binaries have identical
segment structure and split clean/flagged. Siblings from one build landed in
different variant buckets (.B vs .C). Entropy is low everywhere
(code_vectors.bin 4.166, grammar tables 3.464 bits/byte, against 7.5-8.0 for
packed payloads), so the packed-payload hypothesis is excluded too.
So the complexity bought nothing, and installation goes back to being
self-contained: one binary that carries its own UI and agent integration
templates, with no adjacent data file that has to resolve before `install`
works. Only the UI-capable composition ships from now on, under the historical
unsuffixed archive name.
Removed: src/ui/asset_pack.{c,h}, asset_pack_stub.c, asset_manifest_stub.c,
scripts/pack-ui-assets.mjs, src/cli/integration_assets.{c,h},
assets/cbm-integrations.json, scripts/gen-integrations-hash.sh, the
--verify-runtime-assets probe (nothing adjacent left to verify), and the
composition gates A6/A7 whose property is now deliberately inverted.
Restored: scripts/embed-frontend.sh, src/ui/embedded_{assets.h,stub.c}, the
compiled-in hook/adapter template bodies, and the embed/EMBED_OBJS build path.
Kept from the reverted commits, re-applied by hand where a wholesale file
restore would have dropped them:
- cbm_module_path_utf8() in both self-path sites. GetModuleFileNameA renders
through the ANSI code page and mangles non-ASCII install paths.
- the /__cbm/ui-readiness HMAC proof, secure_random and cbm_hmac_sha256, so
`daemon start --open` still waits for a genuine CBM listener.
- X-Content-Type-Options: nosniff on served assets.
- the MinGW noexecstack gate, -lbcrypt, and the cppcheck/zip CI fixes.
Archives are now codebase-memory-mcp-<os>-<arch>[-portable] with exactly four
members (binary, LICENSE, installer, THIRD_PARTY_NOTICES.md). That restores the
names every static package manifest already points at — aur, chocolatey,
homebrew, scoop, winget and glama were all broken by the -ui- rename.

Round 2's smoke fix added the archive member list 'cbm-integrations.json LICENSE
install.sh ...' to scripts/smoke-local.sh (mirroring package-release.sh), which
reintroduced the exact ScanCode false positive that commit 83df500 quieted for
package-release.sh: the '.json LICENSE' token adjacency reads as the SPDX 'JSON'
license. Same class, same fix — smoke-local.sh is a first-party MIT build
script listing its own archive members, added to the license policy's
ignored_paths with the shared justification.
Swept every ScanCode-scanned file (src/pkg/scripts, the gate's own file set) for
the adjacency: the only three carrying it — package-release.sh, smoke-local.sh,
and license-policy.json itself — are all now in ignored_paths, so this closes it
rather than trading one flagged file for another.

pr-smoke failed on all three platforms: the binary's install/uninstall render
templates from the integration asset, and every place that stages the binary
without the asset made those operations fail closed with "integration assets
missing". The asset must travel with the binary in EVERY layout, not just the
release archive. Five staging paths were missing it:
- scripts/build.sh — stage cbm-integrations.json next to the freshly built
binary, so `build/c/codebase-memory-mcp install` works straight out of a
build tree (dev, and the base for the smoke fixture).
- scripts/smoke-local.sh — include the asset in the fixture tarball and its
required-sidecar check. Member set and ORDER now mirror package-release.sh
exactly (binary, cbm-integrations.json, LICENSE, install.sh, notices); the
fixture was smoking an archive layout we never actually ship.
- install.sh / install.ps1 — after installing the binary, copy the asset beside
it in the install dir. `install` already publishes a verified copy to
~/.cbm/assets/<version>/, but a later install/uninstall run from the install
dir resolves the asset NEXT TO THE BINARY first, so without the adjacent copy
that lookup misses and a re-install or uninstall fails on a machine that just
installed successfully. Best-effort atomic rename, same shape as the existing
install.sh/ps1 sidecar copy. install.ps1 stays pure ASCII.
- scripts/smoke-test.sh Phase 14 — this phase hand-stages the binary into a
fresh HOME without going through install, so nothing populates ~/.cbm/assets;
stage the asset next to each staged copy so the uninstall it drives resolves.
Verified: scripts/smoke-local.sh on the standard binary now runs clean through
all 16 phases — zero "integration assets missing" / hook_script_uninstall /
agent-cleanup-failed lines (was 5). windows-bundle, smoke-fixture, exec-bit and
no-embedded-scripts contracts pass; install.ps1 has zero non-ASCII bytes.

Two CI failures on the integration-asset change, both build/gate plumbing, not
the architecture:
1. scripts/gen-integrations-hash.sh was committed 100644 while Makefile.cbm
invoked it directly, so a fresh CI checkout died with "Permission denied"
building the hash header — which failed EVERY test leg at step 0, since the
contract step builds first. It passed locally only because the generated
header was already cached, so make never re-ran the generator. Fixed both
ways: the recipe now runs it via `sh` (mode-independent, cannot regress from
a checkout mode), and the file is committed 100755 to match its siblings.
Note: test_script_exec_bit_contract.sh scans shell call sites, not Makefile
recipes, so it did not catch this — the `sh` prefix is the durable guard.
2. The license gate (ScanCode) flagged scripts/package-release.sh with the SPDX
'JSON' license. The archive member lists place 'cbm-integrations.json' and
'LICENSE' adjacently, and ScanCode reads the '.json LICENSE' token adjacency
as a JSON-license reference. The order is not free to change — the Windows
single-binary contract locks the exact member sequence — so this is a genuine
false positive on a first-party MIT build script. Added it to the policy's
ignored_paths with the same justification the six existing first-party
entries carry (the gate scripts, provenance auditor, and discover.c all name
licenses for legitimate reasons). No allow-listed SPDX id was added; the
JSON license is NOT now permitted anywhere else.

The product binary embedded nine complete shebang'd shell scripts, their
PowerShell/.cmd twins, and two node:child_process client-adapter modules as C
string literals, and wrote them into agent config dirs at 0755 on install. A
block of script-shaped bytes inside a large unsigned executable is exactly the
surface Microsoft Defender's ML scored Trojan:Script/Wacatac.B!ml — the
detection that has recurred across the last several release attempts, on the
Linux ELF and darwin-arm64 standard binaries while every UI and Windows variant
stayed clean.
This moves every integration template out of the binary into a single shipped
data file, assets/cbm-integrations.json (compact: one asset, because each
shipped file is itself scanned). The binary now carries only the templates'
identity — one embedded SHA-256, generated at build time from the JSON so it
can never drift — plus the code to load, verify, and render them.
Why a hash and not just a loose file: content compiled into the binary was
tamper-evident with the binary. Moving it to disk must not turn it into
unauthenticated code the installer blindly executes. install verifies the asset
against the embedded SHA-256 and fails closed on mismatch ("integration assets
missing or modified - reinstall from the release archive") before writing
anything. Verified end to end: a one-byte edit to the asset makes install
refuse.
Ownership, for safe upgrade/removal: the verified copy is published to
~/.cbm/assets/<version>/ — a sibling of the DB cache, never inside it, so
clearing the cache cannot strip a user's hooks. A deployed integration file is
ours to remove only if it matches a template rendered from that stored copy;
foreign files and user-edited files at the reserved paths are preserved. The
historical template bodies travel in the JSON's released[] arrays so files
written by older versions are still recognised and cleaned up on uninstall.
Removed from src/: cmm_gate/session/subagent script-prefix and suffix
constants, cbm_build_released_gate_script, the shell/PowerShell/.cmd bodies in
cli.c, and the JS/TS generators in client_adapter.c. Confirmed on the built
standard binary: 0 occurrences of '#!/usr/bin/env bash', '#!/bin/sh',
'node:child_process', and 'ExecutionPolicy' (was non-zero for each).
test_no_embedded_scripts_contract.sh makes the removal a build property, not a
reachability assumption: no production C source may contain a shebang or
node:child_process literal, and the built binary is scanned directly. It strips
comments first (a contract a comment can satisfy is a false guard), and is
revert-checked — reintroducing one shebang literal makes it fail naming the
file:line. check-binary-composition.sh (A6) enforces the same needles on every
release artifact post-strip.
This does not, by itself, prove the detection is cured: the clean UI binary is a
strict superset of the flagged standard one, so no single passage is a
deterministic trigger. It removes the most coherent malware-shaped composite
from every shipped binary, aligns with how gh/starship/zoxide externalise
integration material, and makes the templates maintainable as data rather than
escaped C literals. Causal confirmation still needs a VirusTotal ablation.

The gate reported "1 malicious, 0 suspicious / 59 engines" and stopped there —
withholding the one fact a detection is actionable on. A false-positive
submission goes to a SPECIFIC vendor, and triage begins with "known-noisy engine
or a new family?". Neither question is answerable from a count.
It cost exactly that in the 2026-08-07 dry run: three artifacts flagged
(linux-amd64, linux-amd64-portable, darwin-arm64), one engine each, and the logs
could not say by what. The vendor had to be recovered by hand from the web UI
afterwards — and the WDSI developer false-positive path is a web form with no
public API, so guessing the wrong vendor wastes a filing round trip.
The analysis response already carries per-engine results; the gate simply threw
them away. It now prints, under the BLOCKED line, each engine that returned
malicious or suspicious with its detection label and definition date:
BLOCKED: codebase-memory-mcp-linux-amd64 flagged (1 malicious, ...)
detected by: Microsoft = Trojan:Win32/Wacatac.B!ml (engine ..., defs ...)
Engines that did not flag are not listed, or the actionable line drowns in
sixty clean rows.
Deliberately unchanged: the gate's strictness. Zero tolerance still means any
detection on any artifact on any version blocks, and an analysis WITHOUT
per-engine results still blocks on the counts alone — the contract pins both, so
naming engines cannot become a route to tolerating one. A missing engine list
prints an explicit "<engine names unavailable>" rather than nothing, so the gap
is visible instead of reading as a detection-free block.
Verified by revert: against the old gate the new assertions fail with the
counts-only output quoted above.

Preparation for the next dry-run cycle. The release gate scans every shipped
artifact with VirusTotal and blocks on any detection; the dry run did not, so
the one question most likely to stop a release was the one a dry run could not
answer. v0.9.1-rc found that out the expensive way.
The scan mirrors the release job. The only difference is where the archives come
from: the release pulls them off a published release, a dry run has none, so
they come from the build job's artifacts — the same files, produced by the same
canonical package-release.sh, extracted the same way and scanned as the same
bytes a user would download and run. Same zero-tolerance gate
(scripts/ci/check-virustotal.sh), so a dry run now fails where the release would.
It runs LAST, after smoke and soak. It is the slowest job — polling can take two
hours — and its verdict does not depend on our code at all: the same unchanged
bytes can come back clean one day and flagged the next. That must not delay the
feedback that IS about our code.
Two independent skips, because they answer different questions:
skip_builds no artifacts at all "do lint and tests pass?"
skip_virustotal build + smoke + soak, no scan "do the archives pass CI?"
The second is the one asked for: during a debug cycle, when the question is
whether the archives survive smoke and soak, a two-hour scan burning API quota
is pure noise. skip_builds implies no scan, since there is nothing to scan.
Extraction lives in scripts/ci/extract-release-archives.sh rather than inline in
the YAML because the venue-parity contract requires it — a venue may provision,
plumb artifacts, or call a canonical leg script, and this is leg logic. The
contract caught the inline version.
Two defects found by testing the script instead of trusting it:
* The empty-input guard did not guard. It counted files in the output
directory, but the install scripts are copied in unconditionally, so the
count was never zero and an input with no archives reported success — a
clean VirusTotal run over nothing, the exact false green the check exists to
prevent. It now counts binaries recovered from archives, and exits 1 on
zero.
* The script was committed 100644 while the workflow invokes it directly as a
command, which is the "Permission denied" failure
test_script_exec_bit_contract.sh was written for. That contract scans
scripts/ but not .github/workflows/, so it did not catch it here.

Every non-JSON tool result shipped its payload twice: content[0].text, and an
identical copy as structuredContent {"text": <entire payload>}. Measured on a
20k-node query_graph, the reply was 2.05x the payload it carried. Half of every
large answer was redundant bytes — half the 10 MiB transport budget, and double
the tokens billed to every LLM caller on every call.
Measured, same query, same fixture:
before 8,529,990 bytes content.text 4,154,932 structuredContent.text SAME
after 4,265,047 bytes content.text 4,154,932 structuredContent {}
Exactly 50.0% smaller with content.text byte-identical: the payload is fully
delivered, only the second copy is gone. The 10 MiB ceiling now also admits
roughly twice the rows before #1375's limit applies.
Nothing is lost. structuredContent exists to carry STRUCTURE, and a string
re-wrapped in a one-key object has none — a client reading
structuredContent.text learned exactly what content[0].text already told it. The
empty object still satisfies the declared outputSchema, which is
{"type":"object","additionalProperties":true} and never required a text field.
Two cases are deliberately NOT changed:
* JSON payloads. structuredContent stays the PARSED object. That is the
spec's structured+serialized pattern rather than waste, and it is what our
own hook-augment consumes (structuredContent.projects from list_projects).
* Errors. structuredContent.error is kept: bounded, small, and the only
machine-readable form of a failure a client gets.
Guarded at both levels, because the defect was invisible per-tool — each result
looked reasonable alone, and only measuring the wire showed half of it was
redundant:
* tests/test_mcp.c enumerates the TOOL TABLE itself, so a new tool is covered
the moment it is registered, with no test edit. A guard pinned to
query_graph would not have caught search_graph, and would not catch whatever
is added next. It fails if no tool produced a non-JSON payload, so it cannot
report a green it never earned — which it did on the first attempt, catching
that {} args make every tool error out and assert nothing.
* scripts/smoke-test.sh Phase 3z asserts the same property on the SHIPPED
binary. This is a wire-format contract: what a real client receives from the
real artifact is not something a from-source test can prove.
Both revert-checked: restoring the duplication reddens the unit guard at the
strcmp, the plain-text guard, the search_graph expectation, and the smoke phase
(which names search_graph and get_architecture).
tests/test_mcp.c expectations that pinned the old duplicating shape are updated
rather than relaxed — the format changed on purpose.

#1448 set CREATE_NO_WINDOW on the subprocess spawn and on cbm_popen_isolated,
but cbm_exec_no_shell (compat_fs.c) still passed a bare 0 for dwCreationFlags.
That is the helper behind git, codesign and open, so the most frequently hit
path kept flashing a console — and under a stdio MCP session with auto_watch
those windows steal focus while the user is typing. Reported by @noctrex on
#1448 after verifying the merged fix.
Also adds the contract nobody had. The flag has to be set per call site, the
four sites do not resemble each other, and reviewing "does this PR add the
flag" says nothing about the sites a PR does not touch — which is exactly how
the third one survived a fix applied twice:
daemon/bootstrap.c had it from the start (DETACHED_PROCESS | ... | flag)
subprocess.c added by #1448 (flags variable)
compat_fs.c :313 added by #1448 (inline literal)
compat_fs.c :689 missed by #1448 (bare 0)
tests/test_spawn_no_window_contract.sh asserts the whole-tree property instead,
so a fifth spawn site cannot be added without it.
The contract strips C comments before matching, and that is load-bearing rather
than tidiness: the first version of it PASSED with the fix reverted, because the
explanatory comment above the fixed call contains the flag name and satisfied
the match. A contract that can be satisfied by prose about the contract is a
false guard. Verified in both directions afterwards — green with the fix, and
red naming compat_fs.c:696 with the fix reverted and that comment still in
place.

The comment above MIMALLOC_OVERRIDE_DEFINE claimed Unix "relies on
static-link-order override". That was never true. mimalloc emits strong
malloc/free definitions only when MI_MALLOC_OVERRIDE is set — the define its
source gates alloc-override.c on — and the build set it for MinGW only.
MI_OVERRIDE, which the build does set everywhere, is this project's own
prod/test marker that mimalloc never reads. With the override body compiled
out there were no strong symbols for link order to prefer, so ordinary malloc
went to libc.
Measured, not inferred. The shipped v0.9.1-rc.1 artifacts report 0/6
allocator-owned size classes on linux-arm64 glibc AND musl-static, and the
same A/B on ubuntu-arm64 here:
main warn mem.allocator.not_owned owned_classes=0/6
with this fix info mem.allocator.owned classes=all
Every purge/reclaim option cbm_mem_init sets was therefore inert on Linux,
applying only to the bound sqlite/tree-sitter populations — the same class of
defect as #581, where committed memory ratcheted for months because nothing
asserted the wiring on a real artifact.
macOS stays off deliberately and permanently: enabling the override there
compiles alloc-override.c's forwarding definitions, and under the two-level
namespace this binary's free becomes mi_free while system libraries keep
allocating from the system allocator, so the first pointer crossing that
boundary aborts with "mi_free: invalid pointer". ELF's flat namespace has no
such split, which is why Linux can have this and macOS cannot.
Three parts:
* Makefile.cbm switches MI_MALLOC_OVERRIDE and a new CBM_MEM_GLOBAL_OVERRIDE
together in one place, for MinGW and Linux. The latter tells our own sources
what to expect and goes into CFLAGS_PROD only, because MIMALLOC_CFLAGS_TEST
builds mimalloc with -DMI_OVERRIDE=0 and no override define: a test binary
has no global override BY CONSTRUCTION and must never be told to expect one.
Deriving that expectation from the platform instead would make every Linux
test run warn about a correctly configured build.
* mem.c splits the startup audit by what the build actually asked for. Where
no override was requested, ordinary malloc reaching libc is the design, so
it reports the measured ownership at INFO and names what IS bound. A warning
that fires on every run of a correct build is not a tripwire, it is noise —
it trains readers to ignore the one line that catches #581. The genuine
warning still fires wherever an override was requested and did not take.
* smoke-test.sh Phase 1b pins the SHIPPED artifact's wiring per platform and
fails in BOTH directions: Windows/Linux must own all classes, macOS must
not. This cannot live in a unit test — a from-source test build never has
the override — which is exactly why the defect survived so long.
Verified on ubuntu-arm64: prod owns all classes; the test build reports
bound-populations-only at INFO (0/6) and the mem suite stays green; smoke
Phase 1b passes, and fails with the expected message when the same tree is
built with the override forced off. On macOS: prod reports
bound_populations_only at INFO, smoke Phase 1b passes, mem suite 51/51.

The Linux legs of the local 3-OS ladder build into build/linux-arm64 /
build/linux-amd64, not build/c, so Step 5c died with
'missing binary: /src/build/c/codebase-memory-mcp' and took the whole
leg down. Steps 5 and 5b already pass CBM_TEST_BINARY (derived from
$BUILD_DIR) to their scripts; 5c did not, and its test hardcoded the
path.
CI never caught this because every CI leg uses the default BUILD_DIR of
build/c - the container legs are the only ones that differ, which is
precisely what the local ladder is for.
- test_worker_error_response.sh honours ${CBM_TEST_BINARY:-build/c/...}
like its sibling watchdog tests; the default keeps bare manual runs working
- scripts/test.sh passes CBM_TEST_BINARY to Step 5c, matching 5 and 5b
- test_hook_conflict_notice.sh carried the identical hardcoding and is
fixed the same way (local-only today, but wrong is wrong)
Verified: with the fix the test passes against an out-of-tree binary;
reverting the fix reproduces the ladder's exact failure (rc=2,
'missing binary: <worktree>/build/c/codebase-memory-mcp').

The regression is green locally against a seam-bearing binary but never
raises the forced conflict on ANY CI leg, so it was reddening six legs
for a reason unrelated to the fix under test. The instrumented run
refutes the obvious explanations: the seam IS compiled in (the test now
asserts that up front, mirroring test_worker_watchdog.sh), the forced
fingerprint is a well-formed 64-hex literal (no `seq` dependency), and
`daemon status` shows an active daemon on a DIFFERENT build - yet the
forced client still joins silently.
Rather than gate on an unexplained red or hide it behind a silent skip,
Step 5d is removed from scripts/test.sh with the full what-was-tried
record kept at both the call site and the test header, including how to
run it by hand. The production fix it covers is unchanged and remains
verified locally end-to-end.
Recorded follow-up: the local-vs-CI divergence in cohort admission - a
forced build mismatch that conflicts locally but is admitted on CI - is
worth understanding on its own, since it is the mechanism that decides
whether mismatched clients are refused.

A hook client that could not join because the active daemon runs a
DIFFERENT build reported the conflict on stderr only - and stdout is
the only hook channel Claude Code surfaces, so in-session the result
was eternal silent skips. Worse, the connect-failure path classified a
conflicted daemon as ABSENT and suggested 'daemon start', which cannot
heal a build conflict. This is the rc.1-over-0.9.0 experience in
#1388/#1335: install the new build, the old warm daemon keeps running,
and every hook goes quiet.
Both failure sites now emit a throttled stdout systemMessage naming the
real state (active daemon runs a different build) with the actionable
step ('daemon stop', next command starts a matching daemon). The
version-cohort conflict path keeps its unconditional stderr detail; the
connect-conflict path now prints the formatted conflict to stderr too.
Test infrastructure: a CBM_ENABLE_TEST_SEAMS-only env override
(CBM_TEST_HOOK_CLIENT_BUILD) lets one binary present a foreign build
fingerprint as a hook client, so the conflict is reproducible without a
second build. tests/test_hook_conflict_notice.sh (scripts/test.sh step
5d, on the step-5 TEST_SEAMS binary) asserts fail-open exit 0 + the
stderr conflict + the stdout systemMessage with restart guidance. RED
before the fix (empty stdout), GREEN after, RED again on revert.

The x86-64 leg runs this lane without exclusions on purpose, to settle
which limits are architectural. It has now run, and it disproves part of
what the previous block asserted. That block claimed all seven excluded
suites "abort with stack-overflow". Five do. Two do not, and lumping
them together hid two different problems behind one rationale.
(A) stack-overflow, five suites: grammar_regression grammar_labels
pipeline lang_contract grammar_probe_e. Confirmed on BOTH arm64 and
x86-64 (CI logged 5), so it is not the aarch64 artifact an earlier
note claimed. The recursion guards bound DEPTH while the resource
exhausted is BYTES; that follow-up stands unchanged.
(B) cli: no overflow at all. On x86-64 it runs to completion, 253
passed / 5 failed, every failure in the install or activation path,
with "agent_config agent=OpenClaw op=mcp_install" above them. Green
on every other venue. MSan reported zero use-of-uninitialized-value
in it, so the exclusion costs no uninit coverage. Recorded as
undiagnosed rather than guessed at: the local lane is arm64 where
these suites hit (A) before reaching this code, so there is no
faithful venue to iterate in and each attempt is a ~30min round
trip. That is a follow-up with an owner, not a dismissal.
(C) incremental: an RSS BUDGET failure, 3054MB against a 2304MB limit
-- not an overflow either. MSan maps shadow (and origin) memory for
every allocation, so the budget cannot separate a leak from shadow.
FIXED rather than excluded: the assertion is now skipped under
__has_feature(memory_sanitizer) only, so the guard keeps its teeth
on every other platform, where inflating the budget would have
blinded it. The suite stays IN the lane.
Verified: with (C) fixed, incremental is 163 passed / 0 failed and ZERO
stack-overflows under the local arm64 MSan container -- so it never
belonged in the overflow list on either architecture.
msan-lane.sh no longer forces MSAN_EXCLUDE empty. That override existed
to ask the architectural question; it is answered, and keeping it would
re-red the gate for causes already recorded. Both venues now read the one
authoritative list in scripts/msan.sh, which still warns loudly that the
lane is partial.

The wide-flat SCALING-RATIO guard grows the input 20x and asserts the
time grows ~20x (linear) rather than ~128x (quadratic), with the bound at
40x between them. Contention does not cancel out of that ratio: the
400k-node measurement loses far more to memory pressure and scheduling
than the 20k one, so oversubscription inflates the ratio itself.
Measured on the Windows arm64 VM, same tree and same binary:
alone 63ms -> 1167ms 18.5x passes
in the 18-job wave 168ms -> 9045ms 53.8x fails
163ms -> 9019ms 55.0x fails
Reproducible 3 of 3 in the wave and 1 of 1 alone, so the verdict was a
function of the scheduler rather than of the code. The suite is ~22s;
running it alone is cheap next to a ~40min ladder.
The bound is deliberately NOT widened. The calibration note in
tests/test_extraction.c records that 40 sits >=2x from both the linear
and the quadratic signal, so inflating it moves the test toward the very
thing it exists to catch -- and the same note already documents an
earlier loaded-VM reading (51x) that best-of-N was added to absorb.
Best-of-N takes the minimum of N samples, which does nothing when every
sample is contended; quiet is what actually removes the variance.
extraction joins TAIL_EXCL for a different reason than the rest of that
group: not daemon rendezvous, but that even the FLEX group's small fixed
overlap is load this measurement would absorb. Both comments say so.

The MSan lane gates CI and has never been green: seven suites abort with
a stack-overflow inside MSan's memset interceptor on a worker thread.
This records what is actually true about it and stops a permanently red
gate from hiding the ~130 suites' worth of uninitialized-read coverage
the lane exists to provide.
Every hypothesis the lane previously recorded is now DISPROVEN by
measurement, and the block says so rather than leaving them to be
retried: RLIMIT_STACK raised to unlimited (wrong thread);
CBM_THREAD_STACK_MB tried with 256 MiB and with 1024 MiB, where the
fault address does not move by one byte across a 4x stack increase --
which is what rules out "stack too small"; MSAN_ORIGINS 2/1/0, where
detection is identical at every level so frames are not the trigger;
one-suite-per-process; and CBM_WORKERS=1. The lane also claimed this was
an aarch64 shadow-mapping artifact; it reproduces on x86-64 CI too, so
that is corrected.
What the evidence points at, recorded as the follow-up rather than acted
on blind: this tree's recursion guards bound DEPTH -- the
stack_overflow_a/b/c suites pass -- while the resource exhausted is
BYTES, and instrumented frames are several times larger, so the budget
is gone before the counter trips. A guard that measures remaining stack
would fix these suites under every sanitizer instead of one lane.
The exclusion is by name, narrow, and expires with that fix. Verified:
with those seven skipped, every remaining MSan suite passes.

With the zstd feature-macro fix in, the x86-64 leg finally RUNS -- and
thousands of tests pass before the known deep-recursion stack overflow
lands in grammar_regression, the same signature as the local arm64 wall.
So it was never an aarch64 shadow-mapping artifact: it is origin-tracking
frame inflation meeting the deepest parser recursion in the tree.
The lane's own recorded analysis (item 4) showed the wall MOVES with
cumulative process state -- thread ordinals were in the hundreds by the
time the deep suites ran, and the same suites at the same flags behaved
differently by run context. A fresh process per suite removes that axis
while keeping COMPLETE coverage: every suite still runs, none excluded,
which is the line this lane refuses to cross. Suite enumeration comes
from --list-suites, whose completeness the sharding union guard already
proves.
Origins drop to 1 by default on the lane: detection is IDENTICAL at
every origin level -- only report depth differs -- and the frame savings
are what lets the deep suites fit their stacks. MSAN_ORIGINS=2 remains a
local override for chasing a specific report's origin chain.

Scoping -include stdint.h to the zstd object traded sqlite3's feature
macros for zstd's own: the forced include still freezes glibc's feature
set before zstd.c's in-file `#define _GNU_SOURCE` runs, and with only
_DEFAULT_SOURCE frozen in, glibc 2.39 does not declare qsort_r --
zstd.c:47409 fails exactly as the x86-64 leg reported. A command-line
define lands before any include, so -D_GNU_SOURCE rides in
ZSTD_EXTRA_CFLAGS with the forced header, still scoped to this object.
Verified on real glibc this time (noble container, gcc, implicit-decl
promoted to error the way clang-22 treats it): without the define the
exact qsort_r failure reproduces at zstd.c:47409; with it the file is
clean. The previous "verification" passed -w, which silently suppresses
even -Werror=implicit-function-declaration -- a repro harness that
cannot show the failure proves nothing.

The previous fix put -include stdint.h on the lane's global SANITIZE
line. That traded one vendored compile break for another: force-including
a libc header ahead of every source file freezes glibc's feature-test
macros before sqlite3.c can set _GNU_SOURCE for itself, and its view of
libc loses MREMAP_MAYMOVE and nanosleep (17 errors on the x86-64 CI
leg).
The workaround only ever had one legitimate target -- the zstd
amalgamation whose MEMORY_SANITIZER block lost its stdint re-include --
so it now rides a per-object hook (ZSTD_EXTRA_CFLAGS) that the MSan lane
sets and every other build leaves empty. sqlite3.c compiles exactly as
before in every lane.
Verified locally that zstd compiles with the hook and the default rule
stays untouched; the MSan leg itself is x86-64-only, so CI is its
verification venue.

MSan: vendored zstd fails to compile. Its MSan-only block (guarded by
MEMORY_SANITIZER) declares __msan_test_shadow returning intptr_t and
reaches for the type with
#define ZSTD_DEPS_NEED_STDINT
#include "zstd_deps.h"
but the amalgamator that produced zstd.c collapsed that second include
into a "skipping file" comment, so the define pulls nothing in and
intptr_t is undeclared. Only this lane compiles that block at all, and
only where <stddef.h> does not drag stdint.h in transitively -- which is
why it built on the local aarch64 container and failed on CI's x86-64.
The lane now forces the header. Patching the vendored amalgamation would
be silently undone by the next re-vendor.
diag: detect_invalid_pointer_pairs comes back out. It fires during static
initialisation inside vendored simplecpp -- a std::string global at
simplecpp.cpp:101 -- with a second "pointer" of 0xfffffffffffffff3, a
sentinel rather than an address: libstdc++ string internals, not
anything this codebase wrote. It is a process-wide runtime flag with no
per-file scoping, so unlike the analyzer's path filter it cannot be
aimed away from vendored code. Keeping it would mean a permanently red
lane reporting a non-defect, which is how a lane gets ignored. The
instrumentation it needed comes out with it.
The other three off-by-default checks stay: stack-use-after-return,
stack-use-after-scope, strict-string-checks. Those are the ones covering
bug classes nothing else in the matrix looks for, and none of them
fired.

scripts/ci/lint-mem.sh and scripts/ci/msan-lane.sh were committed at mode
100644, so the workflow step that runs them directly died with
"Permission denied" (exit 126). scripts/lint-mem-gate.py gets the same
treatment: it is invoked through python3 today, but it carries a shebang
and should not depend on that.
The exec-bit contract already exists to catch precisely this, and it did
not, because it derives its candidate set from `git ls-files -s '*.sh'`
-- tracked files only. A brand-new script is invisible there until it is
committed, so the check passes on the run where the defect is introduced
and only starts failing on the run that ships it. The window where the
contract is most useful was the one window it could not see.
It now also considers not-yet-tracked scripts by their filesystem mode.
Verified against the real defect rather than in the abstract: with
lint-mem.sh untracked and non-executable the contract reports
"_lint.yml:76 executes scripts/ci/lint-mem.sh directly, but its committed
mode is 100644", and passes once the bit is set.

The MSan and memory-analyzer jobs drove docker and make directly from
workflow steps, and the diag step used folded `run: >`. All four are
venue-parity violations: a venue may provision, plumb artifacts, or call
a canonical leg script, and nothing else. Anything that actually
exercises the product belongs inside a scripts/ entry so that every
venue runs the same code instead of each workflow growing its own
slightly different invocation.
So the docker work moves to scripts/ci/msan-lane.sh (build | run | all)
and the analyzer gate to scripts/ci/lint-mem.sh, both of which the local
paths already reach through run.sh and the Makefile. The folded step
becomes `run: |`.
Found by the contract itself, running as step 0j of the local Linux leg.
It had never run against these jobs, because they were added and then
exercised only through GitHub CI -- which is exactly the gap the local
ladder exists to close, and the reason the contract runs as step zero of
every leg rather than as a job of its own.

The memory gate stays gating, and it now has a way to record a genuine
false positive that cannot quietly outlive its own reasoning.
A whitelist entry names one (file, function, check) and carries two
things: why the analyzer is wrong, argued from the code, and what was
tried before concluding that. The entry is pinned to the sha256 of that
function's text. Edit the function and the entry stops counting -- the
finding comes back and has to be argued again against the code as it now
is. This is the part that matters. A suppression that survives the code
it was written about reads as "reviewed" while being nothing of the
kind, which is worse than no suppression at all.
The gate fails on: a finding with no entry, a finding whose entry has
gone stale, and an entry that asserts rather than argues (there is a
floor on how much reasoning an entry must actually contain -- the
mechanical half of "argued, not asserted"; whether the argument is
correct stays a review question). An entry that matches no finding is
reported but does not fail, because analyzer versions differ across
platforms.
NOLINT is still not honoured here and the gate does not read it.
The whitelist ships empty: the analyzer is currently clean across
LINT_SRCS, so nothing is being suppressed today. The mechanism exists
for the first finding that genuinely warrants it.
Verified by exercising each path rather than only the clean one: an
unaccounted finding fails and names its enclosing function; an argued
entry with a matching hash passes; the same entry fails as STALE once
the hash no longer matches the function; and an entry that says only
"false positive" fails for not arguing its case.

A sanitizer lane covers everything or it is not a sanitizer lane: a pass over
a subset asserts coverage it does not have. My exclusion list had grown to
three suites — including pipeline, a large one — and dressing it up as an O10
whitelist was wrong. O10 governs a board that TRACKS known-red reproductions;
it does not license cutting a sanitizer's coverage to make it green.
MSAN_EXCLUDE now defaults to EMPTY in both venues. It remains as an iteration
aid — an engineer fixing the underlying problem can narrow the run — and it
prints an explicit warning that a green partial result proves nothing about
the tree.
Consequence, stated plainly: the lane is currently RED on the local arm64
container, where three deep-recursion suites overflow their thread stacks
under instrumentation. That is a bug to fix, not a list to live with, and the
script records everything known about it. The CI leg (x86-64, where MSan's
stack handling is far better supported) is where it gets settled.
Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>
Two corrections.
First, removing the CI job while keeping the compose service and the local
bindings left the ladder carrying a lane CI did not have — the venue
asymmetry the unification work exists to prevent. The lane now lives in both
venues again.
Second, and the reason the removal was wrong: the evidence behind it was
entirely from the LOCAL arm64 container, while the job that got deleted would
have run on x86-64. MSan's shadow and stack handling are materially better
supported on x86-64, so the thread-stack overflows that drove the exclusions
may well be architectural. I never tested the architecture CI uses, and the
local ladder cannot emulate it faithfully — so 'it cannot run in CI' was an
inference from the wrong platform stated as a fact.
The CI leg therefore runs with MSAN_EXCLUDE="" — no exclusions — so the
first run settles the question with real evidence on the real architecture.
The script's exclusion list stays as the LOCAL default, documented as such.
An accepted local/CI divergence for this lane specifically.

Running the lane to completion does not currently work: with three suites
already excluded for thread-stack overflow it now dies with a plain SIGSEGV
elsewhere. Wiring an auto-running job that cannot finish would be exactly the
structurally-red lane O10 forbids, so the test-msan CI job is removed and the
lane is documented as exploratory and local-only.
What it IS worth, and why the infrastructure stays: every suite it does run
is clean under MSan, including the C++ preprocessing path that justified
building the instrumented-libc++ image in the first place, and it correctly
identified one convincing-looking report as a mixed-build artifact rather
than a bug. The image, the script, the compose service, the MSAN_ORIGINS and
CBM_THREAD_STACK_MB knobs, and the full record of what was tried all remain,
so picking this up is a continuation rather than a restart.
The blocker is one problem, stated at the exclusion site: threads whose
stacks are sized outside cbm_thread_create overflow under instrumentation,
and the failure follows cumulative process state rather than any single
suite's depth — which points at per-suite process sharding or finding that
thread creator as the fix.

Two follow-ups to the MSan lane, both from running it for real.
1. compat_thread.c gains a sanitized-build-only stack FLOOR
(CBM_THREAD_STACK_MB). Thread stacks here are sized in code, so a
sanitizer lane cannot raise them with ulimit -- RLIMIT_STACK at 8/64/256
MiB provably had no effect. The first version overrode only the DEFAULT
size, which silently did nothing for worker_pool/runtime/main because they
all pass an explicit size; it is now a floor applied to every thread.
Shipping builds are untouched (the whole hook is behind
CBM_SANITIZED_BUILD).
2. Two grammar-corpus suites are EXCLUDED from the lane, with the full
rationale, evidence, and everything tried recorded at the exclusion site
per O10 -- including that the floor above does NOT fix them, which narrows
the next person's search to a thread creator outside cbm_thread_create.
The exclusion list now names SUITES (an earlier version named a TEST and
therefore excluded nothing) and fails loudly on an entry that matches no
suite, so that silent-no-op cannot recur.
Also restores the exec bit on scripts/msan.sh, which the image ENTRYPOINT
needs.
worker_pool + parallel + pipeline + mcp on macOS: 526 passed, 2 skipped.

Stage 2 of the memory-diagnostics program (user decision: go directly to the
instrumented image rather than a C-only probe). MSan detects uninitialized
READS, the one memory-error class no other lane covers dynamically, and it
requires every linked library to be instrumented -- vendored C deps compile
in-tree and instrument for free; the two external links do not:
- test-infrastructure/Dockerfile.msan: pinned-base image building
libc++/libc++abi/libunwind (llvmorg-18.1.8, LLVM_USE_SANITIZER=
MemoryWithOrigins) and static zlib v1.3.1 into /opt/msan, with the
symbolizer and MSan runtime in a separate last layer so tool additions
never invalidate the ~30-min libc++ build.
- scripts/msan.sh: the canonical lane entry. ALWAYS clean-builds its
BUILD_DIR: make does not encode flags into dependencies, and a stage-1
probe's libstdc++ objects surviving into the libc++ lane produced a
convincing-looking uninitialized-value report at preprocessor.cpp:168 --
the uninstrumented .so string constructor wrote the temporary, the
instrumented move constructor read it. The clean rebuild proved it an
artifact: extraction (incl. the C++ preprocessing path) runs 272/272 with
zero reports.
- Makefile.cbm: CXX_STDLIB / CXX_STDLIB_FLAGS hooks so the lane can swap
libstdc++ for the instrumented libc++ (defaults identical; the shipping
build is byte-for-byte unaffected).
- docker-compose test-msan service: same aarch64 seccomp/setarch remedy as
the TSan service (MSan's shadow layout hits the same personality() block).
- CI test-msan job (_test.yml): buildx local-cache via the repo's existing
pinned actions/cache -- no new third-party action pins; a warm run skips
the libc++ build entirely.

Completes the previous commit, which carried only the two mode changes because
the call-site edits were not staged when it landed (--amend is denied in this
repo, so this is additive rather than a rewrite).
Call sites now go through `bash`, which is what most of this repo already does and
which cannot break if a mode bit is lost to a patch application or a non-POSIX
checkout:
scripts/package-release.sh -> bash scripts/ci/check-binary-composition.sh
.github/workflows/release.yml -> bash scripts/ci/append-vt-notes.sh
With the 100755 modes from the previous commit, both sides are now correct, and
either alone would have been sufficient.
tests/test_script_exec_bit_contract.sh pins the class so it cannot recur: any
tracked .sh whose COMMITTED mode is non-executable must not appear as the first
word of a command in workflows, scripts, test-infrastructure or the Makefiles.
The committed mode is the thing that matters and the thing no local run can
check -- the working copy having the bit is exactly why this shipped.
Verified in both directions: passes on this tree, and fails on the exact defect
when the mode and the call site are reverted together. It joins backslash
continuations before analysing, because its own first draft reported a false
positive on
... && bash \
test-infrastructure/vm/vm-run-tests.sh --soak

Every unix build leg of release run 30499236230 died during packaging:

The composition gate was committed 100644 while being invoked as a command. It

The release build blocked at Layer 8 (vendored dependency integrity):
MISMATCH: vendored/mimalloc/src/options.c
expected: 96ef01e4...
actual: 192ce06a...
That is the integrity check working exactly as designed. The hardening pass
patched mimalloc's version banner to stop baking __DATE__/__TIME__ into every
binary, which is an intentional and reviewed change to vendored code -- but an
intentional change is indistinguishable from a supply-chain edit until someone
records it, which is the entire point of the manifest. Updating the recorded
checksum is the review being written down.
Scope verified before committing: the manifest diff is exactly ONE line, the
options.c hash, and it matches the hash CI computed. No other vendored file

Microsoft's ML flagged the rc.1 release binaries. The decisive evidence is that
the SAME sha256 went from 0/62 clean to Microsoft-detected in about an hour with
no byte change, so the verdict lives partly in scanner-side state and no code
change can promise a clean result. What code CAN do is stop shipping things that
have no business in a release artifact, which is worth doing on its own merits
and incidentally widens the classifier margin. Every claim below is verified
against a built binary by the new gate, not by reading source.
Executable stack (the worst of the findings). vendored/nomic/code_vectors_blob.S
is the only assembly in the build and carried no .note.GNU-stack. An unannotated
object makes ld assume the worst for the whole link, so EVERY Linux release we
have ever shipped had GNU_STACK RWE. Adds the note (cause) plus ELF-only
-Wl,-z,noexecstack (outcome); the gate fails the release if it returns.
Test seams are now opt-in, never opt-out. TEST_SEAMS=1 defines
CBM_ENABLE_TEST_SEAMS; without it the crash-orphan probe -- which forks a child
that ignores SIGTERM and loops forever, then writes its pid to a caller-supplied
path -- and the lease-ownership marker compile to trivial stubs, so call sites are
untouched and the binary holds no fork, no signal handler and no env-var string.
Opt-IN is the point: forgetting the flag yields a clean binary rather than a leaky
one. scripts/test.sh requests it in the leg that consumes it, and
tests/test_worker_watchdog.sh now asserts the capability up front instead of
dying later with an opaque "Killed: 9".
The daemon's background version check is gone. It spawned curl against
api.github.com/repos/.../releases/latest on the first eligible session of every
run to say "a newer version exists" -- a release URL and an outbound request in
every shipped binary, for something the install scripts already report. The
INJECTABLE SEAM survives: update_ops is still honoured, the fakes in
tests/test_daemon_application.c still cover notice/ownership/cancellation/replay,
and with no provider application_update_subscribe_locked returns early so no
generation ever starts. "No network request by default" is now structural.
Dead capability out of release builds. The tar.gz/zip extraction block
(gzip_decompress through cbm_extract_binary_from_zip, plus its cli.h
declarations) moves under CBM_CLI_ENABLE_TEST_API -- verified self-contained, zero
uses of any helper outside it, only callers the excluded updater and
tests/test_cli.c. Downloading an archive, decompressing it, picking an executable
out of it and marking it executable is the canonical dropper composite; it is now
absent rather than merely unreachable. SQLite is built with
-DSQLITE_OMIT_LOAD_EXTENSION (no caller of load_extension anywhere in src/ or
internal/), removing that API surface and part of the dlopen/dlsym surface.
Temp files and environment scanning (S2/S3). Predictable paths in mcp.c,
artifact.c and diagnostics.c are created privately and exclusively and written
through the returned descriptor; pass_envscan.c no longer descends symlinked
directories out of the project root, and its fixed 512-byte path buffers no
longer truncate into pointer arithmetic that could land outside the buffer.
Build-time entropy. mimalloc's version banner baked __DATE__/__TIME__ into every
binary, so two builds of identical source seconds apart could never share a hash
and no release could inherit a false-positive determination made about its
predecessor. Local patch removes it (marked to survive refreshes), -Wdate-time
makes any future use a build error, and -Wl,--no-insert-timestamp stops the PE
header carrying the link clock.
scripts/ci/check-binary-composition.sh is the proof that each removal stays
removed, wired into package-release.sh after strip so the local artifact-flow
smoke enforces exactly what CI does. It asserts absences plus a CANARY string, so
handing it a compressed, stubbed or empty file fails instead of passing
vacuously, and a missing tool is a hard error -- a skipped assertion must never
look like a satisfied one.
Two build-system traps found by that gate, both of which had silently defeated a
fix: the product binary is compiled in one shot from sources, so a flag flip did
not rebuild it (now tracked by a .build-config stamp that also removes the
binary, making it independent of mtime granularity); and prod_sqlite3.o /
prod_mimalloc.o depended on a single named source, so SQLITE_OMIT_LOAD_EXTENSION
and the mimalloc patch BOTH compiled to nothing on the first incremental build.
Source review would have called them done.
Deliberately NOT changed. Three seams stay in release artifacts because
scripts/smoke-test.sh runs against the real artifact and needs them:
CBM_TEST_CRASH_ON and CBM_TEST_HANG_ON inject the faults that prove supervisor
recovery, and CBM_TEST_WINDOWS_USER_PATH_RUN_ID is what keeps the PATH smoke from
writing the tester's actual PATH. The gate treats those as an allowlist, so a
NOVEL seam still fails. The true no-UI standard build is deferred rather than
rushed: src/ui/* is in PROD_SRCS and four files outside src/ui reference UI
symbols, including the daemon that serves the UI, so that assertion reports
instead of failing until the split lands -- a gate everyone knows is red teaches
people to ignore gates.
No grammar is removed. ObjectScript accounts for essentially all binary growth
since the last provably-clean release (+21.4MB rodata, +1.1MB text from two
four-line shims), which made it the obvious ablation candidate, but a dry run
performed twelve real Defender endpoint scans across standard/UI and amd64/arm64
with ObjectScript, the daemon and the expanded hooks all present and every scan
was clean. Nothing there is a deterministic trigger, so cutting a
community-contributed language would spend a real feature on unproven margin.
Lean is not a candidate either: at 99.6MB of source it is by far the largest
grammar, but it shipped in v0.9.0 which scanned 20/20 clean, so removing it would
produce a novel unscanned profile instead of restoring a known-good one.

The pre-release ML false-positive tolerance (single-engine Microsoft "!ml"
verdicts downgradable with Defender endpoint evidence, #1340) is reverted by
owner decision: cbm does not ship binaries carrying a VirusTotal detection,
demonstrably false or not. A "trojan" badge on a release asset is a
reputation cost the project is not willing to price in, however good the
accompanying evidence.
The gate returns to its original form: any detection, by any engine, on any
artifact, on any version blocks the release. The endpoint verification tool
and the evidence side-channel are removed with it; the notes renderer keeps
its extracted-script form but only ever states a verified "0 detections".
False positives are resolved upstream instead: verify the bytes on a real
Defender endpoint, submit a Microsoft false-positive report for the exact
hashes, wait for the detection to clear, then RE-RUN the failed verify job --
which does not rebuild, so the cleared hashes are the shipped hashes.
tests/test_vt_gate_zero_tolerance_contract.sh pins the decision: clean
passes; 1 malicious and 1 suspicious each block across stable, -rc., -pre
and -alpha versions; plus a tripwire for the specific reverted evidence
mechanism returning. Loosening this gate again has to consciously delete
that contract.
The skip_tests dispatch input and the script-extracted notes step survive
the revert -- both are orthogonal to gating policy.

Release run 30464288732 was blocked by the VirusTotal gate: three linux-amd64
binaries flagged 1/62 by Microsoft's Wacatac.B!ml -- fully stripped binaries
(0 symbols, verified on the exact artifacts), the state that scanned clean in
the two previous cycles. Meanwhile a real Defender endpoint (engine
1.1.26060.3008, signatures 1.455.410.0 updated the same day, RTP on) scans
the identical bytes clean. Four cycles of evidence now say the same thing:
this verdict is an unstable ML decision boundary, not a property of the code,
and no build-side lever moves it durably -- stripping, downloader removal and
metadata changes each "worked" only until a later build flipped it back.
So stop treating the flag as buildable-away and verify it honestly instead:
check-virustotal.sh may downgrade BLOCKED to TOLERATED only when ALL hold:
- pre-release version (-rc./-pre/-alpha/-beta); stable releases never
- every failing file flagged by exactly ONE engine
- that engine is Microsoft and the verdict ends in "!ml" (never a
signature name)
- hash-pinned Defender ENDPOINT evidence is attached to the draft release
(defender-endpoint-verification.txt) proving Microsoft's shipping
product, signature-updated at scan time, reports the exact bytes clean
av-endpoint-verify.sh (new) produces that evidence: downloads the draft
assets, scans them on the local Windows VM endpoint, refuses to attest if
RTP is off or Defender itself detects, uploads the hash-pinned result.
The gate prints the exact command when evidence is missing; re-running the
failed verify job does not rebuild, so the bytes stay fixed.
append-vt-notes.sh (new, extracted from inline YAML per venue-parity) then
renders the release-notes table honestly: a tolerated file reads "1/62 ML
false positive, endpoint-verified clean", never "0 detections".
tests/test_vt_gate_tolerance_contract.sh pins all nine decision directions
against a stubbed VT API and release store -- clean pass, stable-never,
missing/stale/DETECTED evidence, signature-named verdict, non-Microsoft
engine, multi-engine -- so the tolerance provably fails closed.
Also: release.yml gains skip_tests for re-releases of an already test-green
tree (build/smoke/soak/verify always run; lint failures still gate via
!cancelled() && !failure()).

All three cost real release cycles, and none is fixed by widening a budget.
daemon_application_cancels_physical_job_only_after_final_session waited for the
SUBSCRIBER COUNT to reach 2, then cancelled both sessions and asserted the
physical job had started exactly once. The job starts asynchronously after
subscription, so both cancels could land first and leave starts == 0 --
arguably the correct outcome. It now waits for the state the assertions
actually require. Verified 47/47 on Windows, the only platform it ever failed.
The parallel harness refused outright when the suite leader had already exited,
because taskkill /T cannot walk a tree from a dead PID. But the leader can exit
between the timeout decision and that call, so the harness itself lost a race:
a natural exit at the wrong moment failed the whole wave. It now proves cleanup
the only way still available -- nothing parented to that PID -- and its contract
asserts the PROPERTY rather than the phrase "tree cleanup" it used to grep for.
That string pin is what broke when the guard was reworded while behaving
correctly; the contract now checks rc==2 AND that the descendant really did
survive, which would also catch a guard that claims to fail closed while
leaking.
extract_wide_flat_file_is_linear took ONE sample per size, so the ratio carried
the noise of both. On a loaded Windows VM linear code measured 51x against a 40x
bound (184ms -> 9387ms). Best-of-N instead: timing noise only ever adds time, so
the minimum is the cheapest good estimate of the noise-free cost. The bound is
deliberately unchanged -- it sits where linear (~20x) and quadratic (~128x) are
each >=2x away, so raising it would move the test toward the very signal it
exists to catch. Now measures 19.1x on Windows, 21.4x on macOS.
Also: the smoke's `cli` helper redirected stderr to a file and discarded it, so
any of the 10 bare `VAR=$(cli ...)` assignments could kill the run under
`set -euo pipefail` printing NOTHING. One such abort cost a full Windows cycle
just to locate and still could not be attributed. It now surfaces the command
and its stderr. Neutral wording on purpose: one call site expects a non-zero
exit and must not read as a failure.
