Rows 67-E1 + 67-E2 (P0-3, #3084) — spec `docs/specifications/06x-release-schedule.md` §2 E · epic #3078 · ticket PMAT-1098

67-E1 — one build graph. The quick-tier step expanded scripts/tree_reader_tests.txt into a && chain of one cargo nextest run -p <crate> per crate: 26 cargo invocations, 26 dependency resolutions, serial runs; 55 min on a one-file YAML PR (run 34449608126) and a 60-min timeout under fleet load on #3063 (#3070). Now scripts/ci_test_tier.sh --filterset turns the same tokens into one nextest filterset ((package(x) & kind(lib)), (package(x) & kind(bin)), binary_id(x::t); an unknown token is ENV, never a dropped target — 8 case rows both polarities) and the step runs ONE cargo nextest run --profile ci --workspace --lib --tests --exclude … -E "<expr>". timeout-minutes: 20 on both quick steps: over that, the quick tier has stopped being quick and fails loudly.

Measured on lambda, warm target dir: the same 39 test binaries as the chain; 65,263 tests run in 240 s, 351 s wall including the build. Per-binary counts differ from the chain by feature unification (aprender-core +199, aprender-orchestrate +36, aprender-test-lib −174): the one graph builds the tree-reader libs under --workspace-unified features — exactly what the FULL tier builds — so the quick tier now tests the same binaries the full tier does.

67-E2 — the queue mirrors the PR. merge_group on a moved main re-derives the PR's own diff from HEAD^1..HEAD on the queue ref and runs the tier the PR ran (the reuse rule is untouched); push to main runs quick on the push's diff; schedule/workflow_dispatch stay FULL (decision D-1: FULL lives in the nightly and the pre-publish dogfood). Over the cap → quick on the touched crates + one cargo check --workspace --all-targets --locked step (check_workspace=1, compile-level integration of every reverse dependent); a root-manifest diff (Cargo.toml, Cargo.lock, rust-toolchain.toml) stays FULL at PR, in the queue and on push — cited from gate_touched_crates.sh, not duplicated. A depth-2 fetch on merge_group/push so HEAD^1 resolves on the shallow checkout — without it the change would look wired and be inert (fail-closed to full with a ::warning::). 39/39 case rows, incl. a mutant row (a queue that always answers full loses the crates).

Orchestrator re-runs: case table 39/39 (E1 23 + E2), YAML parses, check_workflow_path_filters/check_guards_are_wired PASS, make gate 41 checks 0 failed. Two pre-existing rows encoded the replaced decision (push -> full, aprender-core touched -> full) and were rewritten, not deleted silently.

…ier does not do yet The quick tier turns 41 tree-reader targets into a 26-invocation `&&` chain (one cargo per crate, serial, 26 compiles of the shared deps): 55 min on a one-file YAML PR, timed out at 60 under fleet load (#3070). The replacement is ONE build graph filtered by a nextest filterset, so the translation from the registry tokens to that expression is the new load-bearing step. These rows fail now (--filterset is not a flag yet) and pin BOTH polarities: each recognised token becomes exactly one clause, and an unrecognised token is ENV (exit 2) rather than a silently dropped target — a dropped token is a tree-reader test that stops running while the step stays green, which is the failure mode the registry exists to prevent. Row 22 counts clauses against registry lines so nothing can be dropped in bulk either. Row 21 was written fail-open first (`grep -q ":--" && LEFTOVER || NONE-LEFT` passes on EMPTY output) and is hardened here before it was ever green. Refs #3084 Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

GREEN for the rows added in the previous commit. `scripts/ci_test_tier.sh --filterset` turns the tree-reader registry's tokens into a cargo-nextest filterset — `(package(c) & kind(lib))`, `(package(c) & kind(bin))`, `binary_id(c::name)`, UNIONed with `|`. ci.yml's part-2 quick-tier step now runs ONE `cargo nextest run --profile ci --workspace --lib --tests --exclude aprender-gpu --exclude aprender-cuda-edge --exclude aprender-compute -E "$EXPR"` instead of a `&&` chain of one cargo per crate. The binary-id forms are nextest's own and were VERIFIED on this workspace with cargo-nextest 0.9.132 (`cargo nextest list --message-format json`), not assumed: a lib suite's id is the bare package name, an integration target's is `package::target`, a bin's is `package::bin/name`. MEASURED on lambda, warm target dir (both listings from the same tree): one graph 65263 tests, 41 binaries, 39 suites with >=1 test build+list 96s, execution 220.2s, 316s wall, rc=0, 65263 passed 20-crate 65204 tests, 40 suites chain (20 distinct crates, not 26 — the 41 tokens group into 20) The two sets are NOT identical and the difference is entirely FEATURE UNIFICATION, never target selection: * A\B = 258 tests. Features the workspace resolve unifies ON and a per-package resolve leaves OFF (aprender-core hf_hub / inspect::safetensors / format::homomorphic / format::quantize, aprender-orchestrate mcp_json, aprender-test-lib async driver). * B\A = 199 tests, and ZERO of them exist under the workspace resolve at all — they are cfg(feature)-gated out. 197 are aprender-test-lib's browser mock suites, 2 are aprender-present-cli::gate_can_fail. So the FULL tier, which is `--workspace --lib`, never ran them either: the old chain was compiling a DIFFERENT aprender-test-lib than the tier it is supposed to approximate. Aligning the quick tier with the full tier's resolve is the fix, not a loss. * Suite selection is otherwise exact: 41 clauses -> nextest reports "Starting 65263 tests across 41 binaries". The two suites with no tests are aprender-core::setfit_conformance and ::falsification_spec_v10_tests, built and selected in BOTH but empty under default features (they are the full tier's --features setfit targets). * `--bins` maps to `kind(bin)`, not to the whole package. The old chain ran `cargo nextest run -p aprender-present-cli` with NO flags, so it also swept up `gate_can_fail` — an integration target that is in neither the registry nor the unwired ledger, i.e. not a tree reader at all. `kind(bin)` selects exactly what the token claims: the cfg(test) unit tests inside the bins of a crate that has no src/lib.rs (which is the only reason the token exists — `--lib` there is `error: no library targets found`). Both quick-tier steps drop to `timeout-minutes: 20`. 60 is the number that let this step burn 55 minutes on a one-file YAML PR (run 34449608126) and then die at the cap under fleet load on #3063 (#3070); the budget is the assertion. check_tree_reader_tests.sh is untouched and still derives the same 41 targets: its `full_tier_excludes` regex requires `--workspace --lib` followed IMMEDIATELY by ` --exclude`, and the new line has `--tests` in between, so it still reads the full tier's line and only that one (verified by running the regex).

Folded #3108's two commits into this branch (fecb358 and ba69692, cherry-picked with -x). This branch already carries #3107's RUSTC_WRAPPER fix, so with its own fast quick tier it is now one PR that can go green on any runner in the pool:

fix(ci): RUSTC_WRAPPER names sccache itself — the dash wrapper drops CARGO_BIN_EXE_aprender-explain, so every quick-tier PR fails workspace-test #3107's fix: RUSTC_WRAPPER names sccache directly, because the dash wrapper dropped CARGO_BIN_EXE_aprender-explain. It is already on this branch.
This PR's own change: the quick tier is one build graph. The serial tier ran past its 60-minute step limit on a loaded intel box: fix(ci): RUSTC_WRAPPER names sccache itself — the dash wrapper drops CARGO_BIN_EXE_aprender-explain, so every quick-tier PR fails workspace-test #3107's run 34535600563 passed every test, and the step still timed out.
fix(test): pp066 --v15-red fetches its v1.5 commit on a shallow checkout — every fresh yoga guard-tree died exit 128 #3108's fix: pp066_v16_defects.sh --v15-red fetches its v1.5 commit on a shallow checkout, so a fresh yoga container passes guard-tree.

#3108 stays open as a hedge. Whichever lands first puts the pp066 fix on main, and the other becomes a no-op.

Checked locally before the push: pp066_v16_defects.sh and its --v15-red arm both return rc=0, and cargo fmt --all -- --check, cargo deny check advisories and cargo test -p aprender-contracts --lib are all green.

The touched-crate expansion adds <= 0.26 %. The registry was the entire bill. check_tree_reader_tests.sh now derives the MODULE that holds the reader: src/a/b.rs -> a::b, src/a/mod.rs -> a, src/lib.rs -> <root>, an include!()-pulled or #[path]-attached file -> the including/declaring file's module (one grep per crate builds the index). A module it cannot resolve falls back to the WHOLE crate and prints WARN unresolved-include on stderr: a silent fallback puts the 88 % back without anyone noticing. Module lookup is DIRECTORY-scoped, which is not a detail — a crate-wide `mod tests;` match resolved aprender-serve's src/cli/tests.rs to `cli::tests`, an atom matching ZERO tests, where the real path is `cli::cli_tests` (10 rows, 18.1 s). ci_test_tier.sh keeps `targets=` byte-compatible for ci.yml's Quick tier step (module rows collapse to crate:--lib) and adds `filterset=`, the key CI should switch to (spec 6.5, phase 2). --union-touched folds it into the ONE union filterset rather than printing two. Hermetic falsifiers, no cargo: tests/fixtures/tree_reader/ is a tree of .rs files (root / nested mod.rs / leaf.rs / include!()-pulled / #[path]-attached / unresolvable / integration) with three committed goldens; hiding the include-resolver and flattening the module path each CHANGE the golden, and both switches are inert without --self-test. Two latent bugs surfaced when the rows started calling the script instead of sourcing it: `ex=$(full_tier_excludes)` died under errexit on a tree with no workflows, and registry_body's `grep -v` aborted check() under pipefail on a comments-only registry (rc=1, empty message). E1 re-measured over the same 25 PRs: tree-reader half 3,867.1 s -> 1,083.3 s (88.08 % -> 24.67 % of full); E1 total 93.32 % -> 57.82 %, floored by the 11 of 25 PRs that fall closed to full. 578.1 s of the remaining 1,083.3 s is ONE unresolvable reader: apr-cli/src/bin/apr-corpus-ingest.rs, a [[bin]] target whose tests no tier runs today.

Recommendation: 0.67 ships T0 + O2, neither of which needs an NVIDIA dependency. Everything requiring cuda-core/cutile defers to 0.68 behind a driver/toolkit prerequisite no fleet host meets today. Load-bearing findings, all measured on 2026-09-09 (HEAD 1faf09015): - G2/G3: aprender-gpu holds 2,620 tests and is excluded from every required check (ci.yml:417). 444 of them need no GPU and run in 0.10s. - G18: contracts/trueno/ptx-codegen-safety-v1.yaml has asserted a register/ occupancy budget since 2026-04-06, and it is vacuous — the generated macro contract_register_budget! is invoked NOWHERE in the tree, its postcondition names an unbound symbol, its falsifier is prose, and it carries registry: true. Neither review lane found this; it is why the scope is not reduced to T0 alone. - G7/G8/G9: cuda-core 0.3.1 builds on stable Rust with CUDA 12.x but refuses at runtime on driver 570.207, and passes end-to-end on gx10 (sm_121, CUDA 13.0, driver 590.48.01) through load_module_from_ptx_src -> launch. - G12: cutile needs CUDA 13.1+/13.2+; no fleet host qualifies. The draft's "upgrade gx10" step is withdrawn — gx10 is the only Blackwell host and the only cuda-nightly host. Evaluation moves to yoga. - G16/G20: an oracle crate must live in experiments/ with its own [workspace]; --all-features (Makefile:659,994,1010) would otherwise hard-fail make coverage and make mutants for contributors without a CUDA 13 toolkit. Every citation re-verified by script; two line numbers taken from a subagent report were wrong (206/293 vs the measured 207/294) and are corrected, with the lesson recorded in the review record. Refs: https://developer.nvidia.com/blog/introducing-cuda-rust-two-tracks-for-writing-gpu-kernels/ Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01J9cSQynVPYeUkQ2i7ccvrs * docs(spec): operator ordered the gx10 CUDA 13.3 upgrade — executed, T3 unblocked Operator ruling 2026-09-09, verbatim: "false YOU WILL UPGRADE". This overrules the grill's RANK3 and the spec's own §7 recommendation. Per repo doctrine a review lane may not reopen an operator decision. Executed on gx10-a5b5: cuda-toolkit-13-3 (13.3.1-1, sbsa/arm64, 66 packages). No kernel-driver package (asserted driver-free before apt ran); driver unchanged at 590.48.01; CUDA 13.0 left on disk and intact. Result — the T3 blocker is gone (G21): cutile-rs 0.3.1 BUILDS AND RUNS on GB10 sm_121, stable rustc 1.95, 18.13s, JIT through CUDA Tile IR, len=1024 mismatches=0. Before the upgrade the fleet max was 13.0, below cutile's 13.1 floor, and this was untestable. T3 therefore moves into 0.67. Corrections this commit also carries: - G22 / §9.4: the upgrade was FIRST REPORTED HERE as "side-by-side, CI lane untouched". That was WRONG. /usr/local/cuda is a Debian ALTERNATIVES link, not a plain symlink; cuda-toolkit-13-3 registers priority 133 vs 13.0's 130, so the default flipped to 13.3 at 11:32:57 (/var/log/alternatives.log). The check that produced the false green was [ "$(readlink -f ...)" = "$(cat ...)" ]; chk "msg $(cat ...)" $? where the command substitution in the MESSAGE argument consumes $? before it is expanded, so $? carried cat's 0, not the test's 1. Reproduced both ways. Generalises the CLAUDE.md "never read $? through a pipe" rule: capture the status into a variable before any other substitution on the line. - §9.5: the post-upgrade regression gate was RUN, with a control. 2568 passed / 2 failed. Rolling the alternative back to 13.0 and re-running just those two shows 13.3 caused NEITHER: * test_alloc_oversize_100gb — FAILS on 13.0 AND 13.3 (pre-existing) * test_cublas_gemm_f16_... — PASSES alone on both; failed only inside the full suite (load-contended wall-clock assertion) Two pre-existing defects surfaced, both wrong-host assumptions: adversarial.rs:36 hard-codes "impossible on RTX 4090" (gx10 is a GB10 with unified memory, so the 100GB alloc legitimately succeeds), and cublas_tests.rs:174 asserts >50 TFLOP/s — a wall-clock assertion, the class already burned four times. Neither was visible because cuda-nightly.yml:242 runs only the perf053 filter, so the --features cuda suite has never been green on the Blackwell host and nothing said so.

GitHub, every mutation read back from the API rather than assumed: - 16 open issues moved 0.67.0 -> 0.68.0 (#3045 #3024 #3019 #3018 #3013 #3002 #2910 #2909 #2908 #2906 #2905 #2904 #2893 #2891 #2890 #2869).

The replacement is ONE build graph filtered by a nextest filterset, so the translation from the registry tokens to that expression is the new load-bearing step. These rows fail now (--filterset is not a flag yet) and pin BOTH polarities: each recognised token becomes exactly one clause, and an unrecognised token is ENV (exit 2) rather than a silently dropped target — a dropped token is a tree-reader test that stops running while the step stays green, which is the failure mode the registry exists to prevent. Row 22 counts clauses against registry lines so nothing can be dropped in bulk either. Row 21 was written fail-open first (`grep -q ":--" && LEFTOVER || NONE-LEFT` passes on EMPTY output) and is hardened here before it was ever green. Refs #3084 Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * perf(ci): the quick tier's 26 cargo invocations become ONE build graph GREEN for the rows added in the previous commit. `scripts/ci_test_tier.sh --filterset` turns the tree-reader registry's tokens into a cargo-nextest filterset — `(package(c) & kind(lib))`, `(package(c) & kind(bin))`, `binary_id(c::name)`, UNIONed with `|`. ci.yml's part-2 quick-tier step now runs ONE `cargo nextest run --profile ci --workspace --lib --tests --exclude aprender-gpu --exclude aprender-cuda-edge --exclude aprender-compute -E "$EXPR"` instead of a `&&` chain of one cargo per crate. The binary-id forms are nextest's own and were VERIFIED on this workspace with cargo-nextest 0.9.132 (`cargo nextest list --message-format json`), not assumed: a lib suite's id is the bare package name, an integration target's is `package::target`, a bin's is `package::bin/name`. MEASURED on lambda, warm target dir (both listings from the same tree): one graph 65263 tests, 41 binaries, 39 suites with >=1 test build+list 96s, execution 220.2s, 316s wall, rc=0, 65263 passed 20-crate 65204 tests, 40 suites chain (20 distinct crates, not 26 — the 41 tokens group into 20) The two sets are NOT identical and the difference is entirely FEATURE UNIFICATION, never target selection: * A\B = 258 tests. Features the workspace resolve unifies ON and a per-package resolve leaves OFF (aprender-core hf_hub / inspect::safetensors / format::homomorphic / format::quantize, aprender-orchestrate mcp_json, aprender-test-lib async driver). * B\A = 199 tests, and ZERO of them exist under the workspace resolve at all — they are cfg(feature)-gated out. 197 are aprender-test-lib's browser mock suites, 2 are aprender-present-cli::gate_can_fail. So the FULL tier, which is `--workspace --lib`, never ran them either: the old chain was compiling a DIFFERENT aprender-test-lib than the tier it is supposed to approximate. Aligning the quick tier with the full tier's resolve is the fix, not a loss. * Suite selection is otherwise exact: 41 clauses -> nextest reports "Starting 65263 tests across 41 binaries". The two suites with no tests are aprender-core::setfit_conformance and ::falsification_spec_v10_tests, built and selected in BOTH but empty under default features (they are the full tier's --features setfit targets). * `--bins` maps to `kind(bin)`, not to the whole package. The old chain ran `cargo nextest run -p aprender-present-cli` with NO flags, so it also swept up `gate_can_fail` — an integration target that is in neither the registry nor the unwired ledger, i.e. not a tree reader at all. `kind(bin)` selects exactly what the token claims: the cfg(test) unit tests inside the bins of a crate that has no src/lib.rs (which is the only reason the token exists — `--lib` there is `error: no library targets found`). Both quick-tier steps drop to `timeout-minutes: 20`. 60 is the number that let this step burn 55 minutes on a one-file YAML PR (run 34449608126) and then die at the cap under fleet load on #3063 (#3070); the budget is the assertion. check_tree_reader_tests.sh is untouched and still derives the same 41 targets: its `full_tier_excludes` regex requires `--workspace --lib` followed IMMEDIATELY by ` --exclude`, and the new line has `--tests` in between, so it still reads the full tier's line and only that one (verified by running the regex).

Run 34448908554 built a 21 MB CUDA asset on gx10 and died on the upload with `gh: command not found`. Nothing checked the toolset a workflow assumes. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * feat(67-C2): name the missing tool at second zero, not after the GPU build scripts/ci_self_hosted_preflight.sh — defaults jq curl git python3 tar sha256sum rustup cargo; --cuda adds nvidia-smi AND asserts a device is actually visible; --need takes the extras a job knows it wants. `gh` is deliberately NOT a default: the CUDA lane moved to REST with curl+python3 because fleet boxes have no gh (#3074), and defaulting it would re-assert the assumption that failed. Exit 1 is a finding about the BOX, exit 2 a finding about the STEP that called this — merged codes send the wrong person. Identity (runner/labels/arch/glibc, driver under --cuda) is printed and, when PREFLIGHT_OUT or RUNNER_TEMP is set, written as JSON: that file is the fleet probe output. 13-row hermetic case table, both polarities, every tool a stub in a scratch PATH so the verdict does not depend on this box. Two rows were RED for the wrong reason first and are recorded as comments: the script called dirname/basename (now parameter expansion) and the nvidia-smi stub catted a fixture, so --cuda reported zero devices because `cat` was not on the scratch PATH. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * ci(67-C2): every self-hosted job asks the box what it has, before it spends an hour The preflight is now the step immediately after checkout in all seven self-hosted jobs: binary-release.yml build-apr-cuda (--cuda --need docker objdump), smoke-cuda (same; both GPU boxes carry `docker` as a runner LABEL, so a pool that stopped matching its own labels is worth one second), and the two clean-room jobs verify-cuda-assets and summary, which had no checkout at all; plus the gx10 lane in cuda-nightly.yml. Not before `decide` and not before the checkout there: on a yield night the box has no working tree, and a step that bashes a repo path would exit 127 and turn a deliberately-yielded night RED. fleet-toolset.yml probes all three pools daily at 04:47 UTC and uploads toolset-<label>/preflight.json, 90-day retention, plus one table in the run summary. ARTIFACT + SUMMARY, NOT A PR: a PR per day against evidence/ is ~365 machine-written PRs a year through a queue that runs at ~1 PR/hour, so the cost of the record would exceed the record. A zero-row roll-up exits 1 — no preflight.json downloaded is a broken probe, not a clean fleet. The falsifier built its universe from the wrong side and said so: `runs-on` alone saw 3 jobs, missing build-apr-cuda and smoke-cuda, whose selector is `${{ fromJSON(matrix.labels) }}` — the two GPU jobs this row exists for. It now reads the strategy block too, and sees 7.

Proven: through /bin/sh (dash) CARGO_BIN_EXE_aprender-explain is dropped and CARGO_BIN_EXE_apr survives, in the sovereign-ci image and locally; the step's exact build WITHOUT the wrapper compiled clean on yoga (12m42s).

The fixture now spells the bytes (\xe2\x80\x8b), which printf '%b' renders identically under any locale, and selftest() pins LC_ALL=C so a \u fixture fails on every box instead of only on the odd runner. Measured on a75e15460's tree: before, 40/40 under C.UTF-8 and 39/40 with no locale; after, 40/40 under both.

Under the operator rule of 2026-09-10 ("WE DO NOT USE HOSTED GITHUB RUNNERS") a tag cut that way is not done. Each pv target now builds natively on the box of its architecture, x86_64 on yoga and aarch64 on gx10, inside rust:1.93.0-bullseye: the sibling-container pattern build-apr-cpu already uses. gnu assets carry a GLIBC_2.31 floor (cross's aarch64 image was 2.31 too; x86_64 came from ubuntu-latest's 2.39, so its floor drops), and musl assets are static, with musl-gcc named as their C compiler. New checks that can fail: the asset runs on its builder, a musl asset has no NEEDED entry, and a gnu asset imports nothing above GLIBC_2.31. Upload is the apr lanes' REST path, since these boxes carry no gh. Asset names are unchanged, so verify-apr-assets' eight pv names still hold. CROSS_VERSION, used only by the old pv job, is gone, and the header describes the new build.

Only the musl lanes run apt (for musl-tools), which is why the gnu lanes on the same two boxes were green. The matrix now names each target's image: gnu stays on rust:1.93.0-bullseye (glibc 2.31 is its floor), musl moves to rust:1.93.0-bookworm, where apt still installs musl-tools. A static musl binary carries no builder glibc, so the floor promise is unchanged.

WE USE GX10 AND LAMBDA-LABS OR YOGA". Three workflows still ran on GitHub-hosted images: - nightly.yml: ubuntu-latest, ubuntu-24.04-arm, macos-latest x2, windows-latest. The Linux builds now run on the fleet (x86_64 on yoga, aarch64 natively on gx10) inside rust:1.93.0-bullseye, so the nightly's glibc floor drops from 2.39 to 2.31. check-activity and the release job run on the clean-room pool, and the release job deletes the old nightly over REST, because the fleet has no gh. No macOS or Windows self-hosted runner is registered, so those targets leave the nightly until one is. - book.yml (build + Pages deploy) and book-contracts.yml (six jobs) move to the clean-room pool. Both are path-filtered (0 and 1 runs in the last 24 h), so the pool barely notices. scripts/check_no_hosted_runners.sh refuses a hosted image token on any non-comment workflow line, not only on `runs-on:` lines: nightly.yml hid `ubuntu-latest` in a matrix value, which a runs-on-only scan never reads (and check_runner_labels.sh exempts hosted jobs by design). A shrink-only `file:job` baseline can excuse a job while its migration is in flight, and a stale entry is RED. The case table has 12 rows: both polarities, a stale-baseline row and an ENV row. Mutation: re-inserting `runs-on: ubuntu-latest` into nightly.yml turns the real-tree run RED (rc=1); restoring it turns it green. The guard is wired through guard_tree.sh's dispatch (check_guards_are_wired.sh PASS), and bashrs reports 0 errors.

Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * ci(book): self-hosted book jobs install their tools into the run's private root, not the shared home Moving book.yml onto the clean-room pool (#3073) put its three `cargo install` steps (bashrs, the local apr-cli, pmat) under check_cargo_install_private_root.sh, which guard-cargo ran red on yoga-eph (run 34544213071): a self-hosted `cargo install` into the shared ~/.cargo/bin replaces a binary another job on the same box may be exec'ing (aprender#2353). Each install now passes `--root "$RUNNER_TEMP/cargo-tools"`, and that root's bin is added to PATH last, so it resolves first. mdBook, which the guard does not cover, had the same race in ~/bin; it now unpacks into $RUNNER_TEMP/bin. Checked locally: check_cargo_install_private_root.sh OK (43 jobs, 9 installs, none shared) and its case table; check_no_hosted_runners, check_runner_labels, check_workflow_env_defined, check_workflow_path_filters and check_apr_bin_pinned all green.

It turned guard-tree red on this PR for scripts/hosted_runner_baseline.txt, which had held nothing since the pv lane moved to the fleet. check_no_hosted_runners.sh already treats a missing baseline as zero exemptions, the strictest state, so the file goes. A later migration that needs an entry must add the file and classify it in the same change. Checked locally: check_baseline_ratchets, check_no_hosted_runners (real tree + 12-row case table) and check_guards_are_wired are all green. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(gpu): VRAM assertions hold each device to its own size, not every device to the RTX 4090's test_context_memory_info and test_context_total_memory asserted `total > 20 GB` ("RTX 4090 should have >20GB VRAM") on whatever device 0 is. yoga's RTX 4060 Laptop GPU has 8 GB, so this PR's cuda-unit job on yoga-eph failed both while saying nothing true about the card. A per-device floor table keyed by the CUDA device name now holds the 4090 to >20 GB (unchanged) and the RTX 4060 to >7 GB; an unlisted device (gx10's GB10 reports unified memory) gets the structural checks only. Proven on lambda's RTX 4090: both tests green, and a mutant raising the 4090 floor to 30 GB turns them RED (exit 101). cargo fmt --check clean; cargo deny and the aprender-contracts lib tests green. `cargo clippy -p aprender-gpu --features cuda --lib --tests -D warnings` reports 599 errors, none in this change: 551 are the banned unwrap() across the cuda test files, and the two in this file are the pre-existing line 13 (`assert!(... || true)`, overly_complex_bool_expr). CI does not lint these targets. The cuBLAS half of this job's failure ("cuBLAS library not found") was the runner containers' loader path, fixed on yoga and gx10 by LD_LIBRARY_PATH=/usr/local/cuda/lib64 (paiml/infra 4c2afe8). Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * ci(quick tier): the tree-reader step gets 45 minutes, since its measured runs never fit 20 This PR's quick-tier part 2 ("every test target that reads the tree") timed out at its own 20-minute cap twice under train load: run 34542045481 on yoga-build2 compiled 811 crates in ~9 min (a cold per-run target dir, with the shared sccache warm) and was part way through 65,266 tests at the cap, and attempt 2 on intel-clean-room-15 timed out at 20 minutes as well. The "~6 min" figure was never reproduced in CI. 45 minutes is still well under the serial tier's 60; the step is re-tightened once it is measured under load. No guard, test or spec pins the old 20. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(quantize): Q5_K readers decoded an invented layout — every Q5_K tensor on the CPU path and in apr import was wrong ggml's block_q5_K gives sub-blocks 2c and 2c+1 the same 32 qs bytes (low nibbles, then high nibbles) and takes the fifth bit of value l in sub-block s from bit s of qh[l]. realizar's dequantize_q5_k and fused_q5k_dot instead read the two nibbles of one byte as neighbouring values and took the fifth bit from qh[4s + l/8]. aprender-quant, the reader behind apr import, gave each sub-block its own 16 qs bytes, and its quantizer packed that way too. Measured on Qwen3.5-0.8B-Q4_K_M, whose attn_qkv and ssm_out are Q5_K: realizar disagreed with gguf-py on 5,959,751 of 6,291,456 values of blk.0.attn_qkv, and the layer-0 QKV sum was +26.64 against llama.cpp's -17.06. With this change it is -17.0967, and layers 0-2 of the #3091 trace match llama.cpp. Nothing caught it because every Q5_K test compared one aprender reader with another. realizar's dequantizer and fused dot now share a single block walker, so they cannot drift apart again. FALSIFY-QDOT-009 pins both readers to the 256 values that gguf-py (llama.cpp's own reader) produced from a block llama.cpp quantized. A round-trip on data whose sub-blocks all differ pins the packer to that reader; the old ramp round-trip gives every sub-block the same codes, and a packer that swapped sub-blocks survived it. Reverting either reader or the packer turns the tests red. The CUDA Q5_K gemv and gemm kernels carry two more wrong layouts. They get a separate PR. Refs #3091 Pmat-Ticket: PMAT-1101 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(compute,aarch64): gx10 could not run ci / lint — clippy errors only an ARM box sees, and #2567's parallel Q4_K path was never called The gx10-pool1 canary picked up #3089's ci / lint and failed it (job 103137079500). Lint is clean on x86. On aarch64, `cargo clippy --all-targets -- -D warnings` fails in aprender-compute and aprender-present-terminal, and so does the job's `-p aprender` fallback, because both crates are in the facade's dependency closure. - Four SIMD detectors end with `#[cfg(aarch64)] { return Neon; } Scalar`, which leaves the Scalar tail unreachable on ARM. Each tail is now a cfg'd block. - x86-only helpers were compiled on ARM and never called there: the Q6_K value extractor, the BLIS AVX-512 packers, the prefetch and NT-store thresholds, and the 32x6 packing import. Each now carries the x86_64 cfg of its only callers. - rounding.rs imported the NEON backend and never used it. - Five more detectors, in aprender-core, aprender-serve and trueno-ublk, had the same unreachable tail. They only showed up once the crates above them compiled. - Two x86_64-only BLIS packers in compute.rs are also dead on ARM. The cfg belongs on the functions, but compute.rs already carries 11 complexity violations, and the pre-commit gate refuses any edit to the file until it is decomposed. Until then, `mod compute;` carries a non-x86 `expect(dead_code)` with that reason. `expect` becomes an error as soon as the packers stop being dead. One of the dead functions was a real defect. #2567 made the non-x86 matmul_q4k_f32_parallel actually parallel (its doc records 1.21x on GB10), but the only call site sat inside the x86_64 block, so every ARM machine still ran the serial Q4_K kernel. The dispatcher now calls it on non-x86 above the same 8M-element threshold. A new test checks the threaded path against the serial one on every arch; the coverage module that exercised it only builds on x86_64. Pmat-Ticket: PMAT-1102 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cuda): the Q5_K GEMV read each value's fifth bit from a sequential bitmask — every Q5_K tensor decoded wrong on the GPU (#3111) In ggml's block_q5_K, the fifth bit of value l in sub-block s is bit s of qh[l], i.e. byte val_idx % 32, bit val_idx / 32. Q5KGemvKernel read byte val_idx / 8, bit val_idx % 8 instead. Its qs offset and nibble selection were already right, so only the high bit was scrambled. That was enough: on the FALSIFY-QDOT-009 golden block, the GPU dot against a ramp came out 2.659 where gguf-py gives 0.622. Measured on an RTX 4090 by running the new test against the shipped indexing. The only earlier GPU Q5_K test asserted `q5k_gemv(...).is_ok()` on synthetic weights. FALSIFY-QDOT-010 runs the kernel on the golden block from #3110, now a fixture shared via include!(). A one-hot activation must return each of the 256 gguf-py values, and a ramp must reproduce gguf-py's dot. Both tests pass with the fix and fail with the shipped indexing. Q5KKernel (the GEMM) has its own wrong layout: the qh and qs offsets and a 12-bit scale unpack. Nothing in inference dispatches it; only q5k_matvec in the layer-trace path and tests do. It stays tracked on #3111.

I had skipped to 009 because crates/aprender-serve/src/quantize/contract_tests.rs already uses "FALSIFY-007" and "FALSIFY-QDOT-008". Those labels exist only in that file's panic strings. The corpus gate enforces the id sequence of the contract YAML itself, so the entry now takes the next id in the file, 007, everywhere it is cited. Pmat-Ticket: PMAT-1101 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(contract): FALSIFY-QDOT-010 becomes 008 — no gaps in the falsification ids Now that #3110's entry is FALSIFY-QDOT-007 (validate_contracts rejects gaps in the ids), the CUDA GEMV falsifier takes the next id, 008, and the shared fixture's header names 007/008. Pmat-Ticket: PMAT-1104 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(guard): the gemv doc's 1.21x ratio moved ten lines and the shrink-only baseline refused the re-key — the ratio had no receipt, so it leaves; the medians stay guard-cargo on #3112 failed check_perf_claims_cite_receipts.sh: the uncited 'speedup 1.21x' (PERF-010) sat at gemv/mod.rs:226 on main and this branch's ten inserted lines moved it to :236; a moved entry is growth under the line-keyed shrink-only ratchet. Re-keying is refused by design. The raw bench output was never preserved, so the honest remedy is the guard's second one: the ratio is deleted, the two medians remain, and the comment says why no ratio is stated. Baseline shrinks by one (235 -> 234). Both guards re-run green in this tree. Pmat-Ticket: PMAT-1102 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * roadmap: PMAT-1106 — GPU-conditional tests must skip without an adapter (coverage nightly) Pmat-Ticket: PMAT-1106 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(compute): nine GPU tests panicked on a box without an adapter — the nightly coverage run was RED for six days on an environment fact backends::gpu::device::backward::tests called GpuDevice::new().expect("GPU device") nine times. Under cargo llvm-cov on yoga-build2 (a docker runner with no GPU passthrough) the two silu_backward tests panicked and the whole coverage run exited 2 (run 34575134766); the same class in aprender-cgp is #2848. A missing adapter is an environment fact, not a kernel defect: device_or_skip() prints 'SKIP: no GPU adapter on this host (<err>)' and the test returns. Proven both ways on lambda-vector: with VK_ICD_FILENAMES pointed at nothing, 9 SKIP lines and 9 passed in 0.00 s; with the real adapter, 0 SKIP lines and 9 passed in 1.42 s. The box that has an adapter stays the gate. Pmat-Ticket: PMAT-1106 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * ci: re-trigger — the push that merged #3089 in landed while the PR sat in the merge queue and GitHub started no pull_request run for it Pmat-Ticket: PMAT-1102 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(test): falsification_measurement was dark for five months — cargo run needs --bin apr (apr-cli ships two binaries since 2026-04-18), and M008 asserts the exit code follows the printed verdict instead of assuming a jittered simulated run passes The E1 quick tier (#3089) is the first thing to run aprender-core's falsification_measurement_tests target on a PR: m001 died on 'cargo run could not determine which binary to run' (apr + apr-corpus-ingest), and m008 on 'CI thresholds not met' — cbtop --simulated draws jittered brick timings (3/7 bricks over budget, CV 88 %), so whether thresholds are met is a coin flip. Six cargo-run sites now name --bin apr; M008 asserts exit 0 <=> 'Status: PASS', the contract its name states. Both pass locally on lambda-vector.

Repo files now resolve from CARGO_MANIFEST_DIR/../.. (the monorepo_invariants.rs pattern), crate sources (src/audio/stream.rs, src/format/v2.rs, src/audio/mel.rs) from CARGO_MANIFEST_DIR, and p8b judges unsafe_code on the workspace root manifest (the crate inherits [lints] workspace = true). Local: 26/26 + 47/47 under nextest. Pmat-Ticket: PMAT-1102 * fix(ci_resolve_dirty): --apply pushed nothing — it removed the worktree that held the merge Under --apply, resolve_one() merged origin/main into each DIRTY PR branch inside a throwaway worktree, printed a push hint, and then immediately ran git worktree remove -f. The merge commit became unreachable and nothing was pushed, forcing operators to redo merges by hand. This changes --apply to push the merge commit directly. We also add --no-push to preserve the old behaviour but keep the merge reachable by creating a local branch 'resolve/<pr>' before removing the worktree. Hermetic selftests are extended to prove these behaviours. Pmat-Ticket: PMAT-1098 * ci(actionlint): declare the runner labels the org actually carries (yoga, ephemeral, docker, build, ARM64, gb10, ada, perf-solo) Measured from gh api orgs/paiml/actions/runners 2026-09-11; the gpu-quick/cuda-unit jobs (67-C1/D1) ask for yoga/ephemeral/docker and actionlint flagged them unknown. Pmat-Ticket: PMAT-1098 * train A: tree-reader registry re-derived on the merged tree (+aprender-gpu driver::memory::transfer); two triage-receipt rows quoted issue titles carrying throughput literals — elided (claim-literal ratchet) Run 34634920736: workspace-test step 'Decide the test tier' exit 2 (registry drift: > aprender-gpu --lib driver::memory::transfer); guard-cargo step 'No claim literals on user-facing surfaces' exit 1 on docs/audits/triage-PMAT-3124-2026-09-11.md:76-77. Both are the train's own tree, not ENV. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(guard): check_tree_reader_tests.sh derived a box-dependent registry — `printf | grep -q` under pipefail fails on EPIPE when grep matches first, so an excluded crate was not skipped Run 34634920736 workspace-test step 'Decide the test tier': 'line 227: printf: write error: Broken pipe' then drift '> aprender-gpu --lib driver::memory::transfer' (derived only). Locally --update produced no change: the race depends on the box. wired_targets() skipped excluded crates with `printf '%s\n' "$ex" | grep -qxF "$c" && continue`; grep -q exits on its first match, printf gets EPIPE, pipefail makes the pipeline non-zero, `continue` never runs. Every producer|grep -q in the script is now a here-string (no producer process to kill): line 227 plus the self-test's row helper and fixture rows. The SIGPIPE+pipefail class (memory feedback_sigpipe_pipefail_false_red). --self-test 25 rows ok, --check 0, bashrs findings not grown. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(tests): falsify_iter7 match learns AttentionType::HybridGatedDeltaNet — the batch compiled a target no row's quick tier did Train run 34639757080 workspace-test (yoga-build2): error[E0004] non-exhaustive patterns at crates/aprender-core/tests/includes/falsify_iter7.rs:240 — #3099's 33c79fdb9 added the variant to AttentionType and its own quick tier never compiled falsification_model_oracle_tests (aprender-core untouched by that row); the train touches aprender-core, so the batch did. The arm asserts the GQA-shaped bound (kv_heads <= heads) on every size; the unsupported-on-CPU/GPU contract stays with the refusal tests. Local: 116/116. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(tests,ci): spec_checklist_19_inference read 13 repo paths from the crate dir (z10 dark on every box); guards-nightly derives the sccache host dir instead of shipping /home/<user> Train run 34641537515: workspace-test (yoga-build3) z10_zero_overhead_serving 'Specification should exist: NotFound' at spec_checklist_19_inference.rs:250 — every let-bound path in the file now anchors on workspace_root() (CARGO_MANIFEST_DIR/../..), so the 12 'if let Ok(content) = read_to_string(..)' rows stop being vacuous too; local: the whole target under nextest. guard-tree (intel-clean-room-5) step 43: the hardcoded-path ratchet refused guards-nightly.yml for the literal /home/noah/data/sccache the 67-E3 move copied from ci.yml (baselined there, new here); the nightly now derives SCCACHE_HOST_DIR=$HOME/data/sccache and falls back to $RUNNER_TEMP/sccache (cold) inside an ephemeral container. The class is filed as #3130 (77 more vacuous sites in 8 checklist files, sweep in flight). Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(tests): eight spec_checklist targets read repo paths from the crate dir -- 77 vacuous rows now read the tree (#3130) Defect: integration tests under crates/aprender-core/tests/ bind repo-relative paths as bare string literals but cargo/nextest run a test binary with cwd = the CRATE dir, so the file is never found; most rows hid it behind if let Ok and were vacuous. Anchor: Added workspace_root() helper to resolve paths correctly from the crate directory to the repo root.

The row now asserts the contract both ways (ONE serialises as 1; n=5 is refused with the client-visible message); 269/270 locally, the one local-only red (test_completion_request_with_all_params, f32-narrowed temperature vs Some(0.7)) does not reproduce in CI's feature-unified build and is not touched here. pr-review-receipt (gx10-pool1): mutate-guard.sh 232/233 — reject-76-drop survived on arm64 exactly as memory recorded for gx10-pool2; the job goes back to X64 with the issue named in the comment. Not a required check (ruleset: gate, workspace-test). Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(tests): api_coverage all-params row asserts the documented f32 narrowing of temperature — a round trip of 0.7 is f64::from(0.7f32) by contract Train run 34658698055: workspace-test (intel) test_completion_request_with_all_params: left Some(0.699999988079071) right Some(0.7). deserialize_temperature_f64 narrows through f32 on purpose (types.rs: 'the value still narrows to f32 before it reaches a sampler, so the narrowing is checked here too') and returns the narrowed value, so 0.7 can never round-trip exactly; the row was dark (#3130 class) and could never pass. It now asserts the contract. Local: api_coverage 270/270. Pmat-Ticket: PMAT-1098 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(tests): api_integration explain row asserts the endpoint's real refusal (501 Not Implemented) instead of a {200,400,503} set none of which is the contract Train run 34661764325: workspace-test test_apr_explain_exercises_handler failed on 'status in {OK, BAD_REQUEST, SERVICE_UNAVAILABLE}'.
