Martin Vogel 673e523879 fix(security-strings): audit .mcpb manifests as structured text, not as binaries
The v0.10.3 release failed its `verify` gate:

    --- Auditing: scan-...--manifest.json ---
    BLOCKED: Unauthorized URL in binary: https://github.com/DeusData
    BLOCKED: Unauthorized URL in binary: https://deusdata.github.io/...
    === BINARY STRING AUDIT FAILED ===

The blocked URLs are OURS — the .mcpb bundle manifest's own homepage and
documentation fields.

security-strings.sh already knows that URL and dangerous-command auditing are
"designed for compiled artifacts" and skips them for text, keeping the
credential and base64 audits that are universally meaningful. Its detection
just had no case for JSON: `file` reports "JSON data", which matched none of
the shell-script/ASCII-text patterns, so a manifest was audited as if it were a
compiled binary. An MCP manifest is exactly the shape that misfires — it
carries project URLs by design, and a `command` field by specification.

This is the first release to ship .mcpb bundles, which is why it surfaced now:
it is the first time a manifest reached the scanned object set. The bundles
were noted as end-to-end unproven until a stable release; this is that proof
doing its job.

Two changes:
- Classify structured-text artifacts by extension FIRST (.json/.yaml/.toml/
  .md/...), then by `file` type with JSON/XML added. The extension check also
  covers hosts without file(1), where the existing `command -v` guard silently
  left every artifact classified as binary.
- Allow-list our own org root and documentation site, so a compiled binary
  embedding the docs link (the graph UI does) passes on its own merits rather
  than relying on the text exemption.

Tests: the manifest case, plus a control proving the exemption is narrow — the
credential audit still runs on structured text. The existing negative control
(an unauthorized URL in a real binary is still BLOCKED) is unchanged and still
passes, so the binary audit is not weakened.

scripts/ — the canonical leg entries

The doctrine (enforced, not advisory): a venue may provision a machine; only a canonical leg script may exercise the product. Local CI, PR CI, the dry run and the release all call the SAME files below — venues differ only in host specs, architecture and inputs, never in what a leg does. Platform differences (arm64 sanitizer flags, native Windows behavior, the Linux portable binary) live INSIDE these scripts, once, never per-venue. tests/test_venue_parity_contract.sh (run as Step 0j of every test leg) turns any violation — inline harness logic in a workflow, a bypassed wrapper, a missing --help — into a red build.

Every entry answers --help (authoritative, agent-oriented: modes, env, exit codes) and rejects unknown flags with exit 2 + Please consult --help.

The legs

leg entry what a run gives you
test test.sh DEFAULT = the venue leg: static contracts (Step 0a0r) + CLEAN ASan+UBSan build + all suites via the parallel harness + prod-binary guards. --suites a,b = iteration mode (incremental rebuild, subset, seconds). --tsan = the ThreadSanitizer leg. CLANGARM64 gets CI's trap-UBSan flags automatically.
package wrappers ci/test-package-wrappers.sh Go, npm, and PyPI runtime-set publication/lock suites on the current host. CI runs the same entry on Linux and Windows so both platform lock implementations gate.
build build.sh CLEAN production runtime set (native executable + authenticated integration asset; --with-ui adds one content-addressed UI pack). ccache via env.sh makes repeats fast; CCACHE_COMPILERCHECK=content guarantees a hit is byte-identical to a cold compile — never stale. --version, STATIC=1, BUILD_DIR=.
lint lint.sh clang-tidy + cppcheck + clang-format (+ no-skips policy). --ci = the CI gate set (no clang-tidy). Drives the same make targets as make lint/lint-ci.
smoke (unix) smoke-local.sh Stages a full release fixture, serves it on a kernel-assigned port, runs smoke-test.sh (ALL phases incl. download/install/update E2E) inside a disposable HOME/XDG/TMP sandbox. ui variant makes a missing verified UI pack a FAILURE. CBM_SMOKE_ARTIFACT_DIR = smoke an extracted release artifact verbatim (release mode).
smoke (windows) ../test-infrastructure/vm/vm-smoke.sh Same verified runtime-set contract on the real Windows VM, plus the user-PATH registry guard (prepare/verify/cleanup).
smoke-invariants smoke-invariants.sh Production-path resilience battery (MCP handshake, all tools invocable, malformed-input handling, supervised crash/hang recovery) — no fixture server or install E2E. smoke.yml runs an explicitly seam-enabled build on the WIDEST source matrix; release artifacts remain seam-free and use the release-shaped smoke legs above.
soak soak-legs.sh The release-gating soak SEQUENCE: quick then query-leak (the #581 detector — never reindexes, so RSS growth = query-path leak), each guarded by a completion-summary check. --legs quick for the ASan single-leg variant. Duration is per leg.

Internal harnesses — never called directly by a venue (the contract forbids it): smoke-test.sh (phases; wrappers provide fixture server + sandbox), soak-test.sh (one soak run; soak-legs.sh provides the sequence + guards), run-tests-parallel.sh (reached through test.sh).

Conventions

  • Exit codes: 0 = pass · 2 = usage error · 90 = guard (a run died without its completion summary — never counts as green) · anything else = the leg's real failure.
  • Iteration is a flag, not a side-tool: the fast paths (--suites, --legs) are modes of the SAME entry the gates run, so a dev loop can never drift from the venue behaviour.
  • Env sandboxing: the smoke wrappers neutralize every agent-config destination override; a smoke can never scribble on your real config.
  • Iterating on a change: scripts/test.sh --suites <suite> (seconds, incremental, same ASan+UBSan flags as the gate). List suites: build/c/test-runner --list-suites. Debugging a Windows-on-ARM trap: re-run with SANITIZE= for a plain build, or use the emulated win.sh ubsan-* pair for full diagnostics.
  • Before any push (the 3-OS ladder): scripts/test.sh (macOS, full) → ./test-infrastructure/run.sh full (Linux + TSan + smoke) → test-infrastructure/vm/win.sh test-par + guards + smoke-install (+ soak when the change touches memory/daemon paths).
  • Concurrency-touching change: add scripts/test.sh --tsan early — the same leg CI gates on.
  • Release-shaped verification: CBM_SMOKE_ARTIFACT_DIR=<extracted artifact> scripts/smoke-local.sh <binary> [ui] smokes exactly what would ship.
  • A leg is red in CI but green locally: first suspect environment shape, not code — the preflights (win.sh automatic; scripts/ci/preflight-docker.sh) and test-infrastructure/README.md's residuals list cover the knowable differences.
