No other key, version, path, optional flag, dev-dependency or bench entry differs. The CLAUDE hunk in §7 matches §10 verbatim and appends after the existing \"do not touch zones\" list, which §13 confirms is the file's tail region.\n- **Causal chain is closed by independent witnesses.** §16 shows Hemera `default = [\"std\"]`, `std = []`. §18 shows `#![no_std]` with `#[cfg(feature = \"std\")] extern crate std;`. §42 — the actual raw stderr, not a summary — fails at `/tmp/nox-no-std-inputs/hemera/rs/src/lib.rs:55 extern crate std;` while compiling `cyber-hemera v0.3.1`, *before* nox is reached, on `cargo build` (not `check`) for `thumbv7em-none-eabi`. §17 line 54 is the attribute, line 55 the item — consistent. The failure is a feature fact; the two-value edit removes exactly that edge.\n- **Blocker 1 (Hemera cfg/API/backend) is discharged.** §17 inventories 18 sites: 3 `feature = \"std\"`, 14 `hemera_portable`, 1 check-cfg. I checked this against the complete sources, not just the JSON. §21 (`arith.rs`) and §22 (`backend.rs`) contain no `feature = \"std\"` anywhere; every branch is `all(target_arch = \"aarch64\", not(hemera_portable))`. §23 (`profile.rs`) has no cfg at all. §24 shows `permute`/`permute_ct` selecting `Fast`/`Ct` statically with no feature or runtime detection. So disabling std cannot change arithmetic backend or kernel selection — the central v1 risk is now evidence-refuted, not asserted.\n- **The two std-only APIs are genuinely unreachable from nox.** §19: `Hash::to_hex` is `#[cfg(feature = \"std\")]`, but `impl fmt::Display for Hash` and `Debug` are unconditional and produce the same hex. §20: `impl std::io::Read for OutputReader` is gated, but `OutputReader::fill` is not. §26 is the decisive witness: nox's only Hemera surface is `tree::hash_leaf`, `tree::hash_node`, `Hash::from_bytes`, `Hash::as_bytes` — all unconditional. §27's benchmark likewise uses only `hash_leaf`/`hash_node`/`as_bytes`. §25's `StepSponge` uses `field`/`params`/`permutation` only. No `to_hex`, no `Read`.\n- **Blocker 2 (benchmark gate) is discharged with real data, not a waiver.** §14 is the CLAUDE clause demanding \"benchmark — no regressions vs baselines.\" §43/§44/§45 are the actual parent run: exit 0, nine cases, the exact Criterion flags plan step 5 pre-commits to, two jobs, `CARGO_INCREMENTAL=0`. §40 retains per-case median/mean confidence intervals. Plan step 5's \">5% median slowdown or disjoint slower CI → investigate with one paired repeat; indeterminate is red/unverified\" is the right discipline, and it explicitly refuses \"algorithms unchanged\" as an excuse.\n- **Blocker 3 (consumer invariant) is now the right invariant.** §28/§29 replace v1's NeBu-type-identity material with manifest-level Hemera-feature inheritance. I read the raw manifest bodies in §29 and they corroborate §28 row by row: soft3 conformance, trident root, zheng rs, zheng cli, mudra root, bbg rs each declare `cyber-hemera` at a path with defaults on. Only two consumers lose the inherited edge — `trident/silicon` and `nox/cli` — and both declare no Hemera dependency at all, so nothing to break. §29's nox-cli body confirms only `cyber-nox` + `strata-nebu`. §4 additionally scans silicon for `hemera::`/`to_hex`/`OutputReader` and finds none. The additive-feature argument is now backed by named artifacts with hashes.\n- **Blocker 4 (durable guard) is discharged in the right place.** §10/§7 add a named every-commit gate to CLAUDE.md, which §12 establishes is exactly what ring 0 and the release train consume (\"gates are executable and named in each repository's CLAUDE.md\"). It uses `build`, not `check` — adopting v1's advice — so post-monomorphization and codegen failures are caught. \"A missing target or dependency is a red prerequisite, not a passed gate\" closes the silent-skip hole.\n- **Blocker 5 (ring/label) is discharged correctly.** §15 shows nox at layer 1 with `role = \"machine\"`, hemera/strata `part_of = nox`, trident at layer 2 — so the reverse closure reaches another rung and ring 1 is the computed value, as §4 and §3 both state. §12's merge policy requires blast radius equal to the repository for a policy merge; it is not, so `decision` and owner acceptance is the correct disposition, which §3's acceptance section states without inventing new authorization.\n- **Blocker 6 (parent baselines) is discharged, including the uncomfortable parts.** §39 inventories all 67 records with argv, cwd, exit code and first error. Every command plan steps 3–8 introduce has a parent row: 38 thumb build (101), 39 host no-default (0), 40/41 workspace debug/release (0), 42/43/44 std/parallel/brakedown (0), 48 nightly doctests (0), 49 bench (0), 52/53 CLI (0), 55 wgpu (0), 56 honeycrisp (101), 57 clippy (101), 58 fmt (1), 59 trident metadata (101), 62/63 rustdoc JSON (0), 64 tag rustdoc (101), 66/67 package H264 (0).\n- **Self-criticism is accurate where it would be easiest to cheat.** Records 19–37 are labeled dead (Homebrew cargo rejecting `+toolchain`) and §39 says so in a dedicated field rather than hiding them. §46/§47 correct the stale \"acpu unavailable\" story with the real inherited error — `acpu::field::ntt_forward` / `multilinear_eval` absent — and plan step 4 explicitly orders preserving *that* result, not the obsolete claim. §48/§49 show record 46's clippy was invalid (`E0514` incompatible rustc) and 57 with toolchain-bin PATH exposes the real `needless_borrow` at `cli/main.rs:247`. §52/§53 show the exact-tag API gate failing on a stale committed lock, and §3/§4 both call it **unmet** rather than substituting the generated-lock or parent comparison. §39 rows 60/61 returned exit 0 but share `/tmp/nox-no-std-parent-corrected-target`, and the brief, research and plan all refuse to count them as isolation proof — a reviewer-checkable fact in the receipts' `CARGO_TARGET_DIR`, and it holds.\n- **Packaging epoch corroborated.** §38's normalized manifest hash `7c3a3d2d…` matches the §38 filename digest, retains published version requirements, and shows all four path keys gone. §54–§59 are the real debug and release package-H264 runs: 4 tests pass each, with `strata-nebu v0.1.1` compiled from registry (no path) per the stderr. §37's harness pins `=0.1.1` — the older-NeBu risk was measured, not predicted, and §5 correctly declines to generalize from four tests.\n\nI did not run anything, did not read the omitted support (raw streams beyond those inline, Git archives, benchmark samples, portable capsule, review-v1 stdout), and cannot verify the stated sha256 digests or that §17's JSON scan is exhaustive beyond the four complete Hemera files supplied (§21–§23 plus lib.rs/sponge.rs excerpts). I treat the 48-vs-46-file published-source comparison and the `committed-inputs.json` entry counts (§62) as claims, not verified facts.\n\n## Blockers\n\nNone. V1's six items are each closed by an artifact a reviewer can inspect here, and no new blocker is created by the delta.\n\n## Advice (non-blocking, for CODE review)\n\n1. **Record `cargo tree -e features -i cyber-hemera` on the candidate for `--features std` and for `--no-default-features` side by side.** Plan step 3 requires the inverse tree; records 17 and 54 are the parent pair. Make the candidate pair the primary artifact and keep the parent pair beside it, so \"default excludes Hemera/std; std includes it\" is one diff rather than two narratives.\n2. **Also spot-check `parallel`, `brakedown`, `wgpu` feature trees on the candidate.** The closure argument (each includes `std`, so each forwards `hemera/std`) is sound from §8/§9, but it is the one place where the fix could silently under-forward, and it costs one command each.\n3. **State the `thumbv7em-none-eabi` prerequisite where a contributor will see it.** §10 says the target must be installed and that absence is red. Add the `rustup target add` line as a non-executing note in the same CLAUDE section, or contributors will read a red gate as a broken repository.\n4. **Keep the two std-only Hemera APIs named in the PR body.** `Hash::to_hex` and `impl Read for OutputReader` disappear for any downstream that relied on nox's default edge to enable them. §28 shows no current consumer does, but the sentence belongs in the durable record, not only in `feature-audit.md`.\n5. **The exact-tag red deserves its own follow-up with a `blocks` edge.** Record 64's stale `nox-tag` lock is unrelated to this patch and plan step 8 correctly refuses to repair it, but the required last-tag gate stays unmet until someone owns it. Opening that task now keeps it from being re-litigated at every future nox PR.\n6. **At the later publication unit, restate the feature-table risk.** `cargo semver-checks` models the default surface, not the inherited-dependency-feature contract. §3's \"future release floor includes the graph and inherited dependency-feature contract\" is right; make sure it survives into the bump PR rather than living only here.\n7. **Keep verbatim in the PR body:** \"Kadek still resolves unchanged registry nox 0.2.0.\" It is the strongest anti-overclaim sentence in the document, and the one most likely to be dropped in summarization.\n\nThe repair is minimal, the diagnosis is proven by raw compiler output, the dependency whose feature is being disabled has been audited site by site, the repository's own benchmark gate is restored with real parent numbers, the consumer invariant checked is now the one the patch actually changes, the guard is durable and named where policy reads it, and the retained reds — fmt, CLI lint, docs, honeycrisp, trident prerequisite, exact-tag API — are labeled unmet rather than waived.
