The +# gate the release train asserts on does not exist.

Nothing recorded them +# as a check, and nothing would have stopped the train if they had been skipped. +# +# ON THE NAME. The spec says `ci / deep`, and a check called `ci / deep` can only +# come from a job named `deep` inside the reusable workflow this repo calls as +# `ci` — i.e. an org-wide change to paiml/.github with blast radius across every +# consuming repo. This job is named `deep` and emits the check `deep`. Changing +# the SPEC's name is the cheap half of that trade; changing an org-wide reusable +# workflow to match a string is the expensive half. APR-RELEASE-001 §4 should be +# amended to `deep`, and that amendment is part of this PR's description. +# +# WHAT IS AND IS NOT HERE, with the measurement for each: +# +# doctests 978 pass, 0 fail, 428 ignored 192 s HERE +# --no-default-features 0 errors (43 before #3257) 26 s HERE +# examples BUILD 980 targets, 0 errors 83 s HERE +# every `cargo run --example` 980 targets — NOT here, and MEASURED why +# full tests 98,621 tests / 727 binaries ~21 min #3255 +# GPU cuda-nightly.yml owns it +# feature matrix undefined AND untooled — see below +# +# RUNNING THE EXAMPLES — measured, then dropped, and the measurement is the point. +# +# The objection "they are interactive or long-running" is half wrong: slowness is +# what a nightly is FOR, and `.config/nextest.toml` already answers hanging with +# `slow-timeout = { period = "60s", terminate-after = 20 }` so "a genuine hang +# dies at 20 minutes WITH A NAME". `check_examples_run` in aprender-orchestrate +# even sidesteps stdin the obvious way, `cargo run --example X -- --help`. +# +# So I wrote the clause. Then ran it on a random sample of five: +# +# HANG aprender-core::grid_search_tuning +# HANG aprender-serve::imp_700_realworld_verification +# exit101 aprender-serve::debug_q4k_gemv +# ok aprender-simulate::reproducibility +# HANG aprender-serve::bench_barrier_overhead +# +# THREE OF FIVE ran past 60 s on `--help`. These are not CLIs — they are compute +# demos that ignore argv and do the work. `--help` does not make them exit, and +# "hang" is the wrong word: they are RUNNING. A per-example timeout would report +# a working example as a failure, at 980 rows. +# +# (Five is a small sample and the ratio is not the claim; the KIND is. The three +# names are self-evidently long-running demos.) +# +# So the clause as the spec words it — "every `cargo run --example`" — cannot be +# implemented as written against this workspace. What could work, and needs a +# decision rather than a guess: +# +# (a) redefine it as "every example STARTS and does not crash within N +# seconds", timeout treated as PASS. Catches the #2519 class (an example +# that panics immediately) without asserting duration. Cost: ~980 x +# min(runtime, N) — a nightly-scale job, ~2 h at N=10, so it belongs in +# #3255's full-surface lane, not in this 5-minute one. +# (b) have examples DECLARE runnability (a `required-features` convention or a +# manifest list), and run only those. +# +# Clause 3 above — every example BUILDS — already catches the common rot, which +# is compile breakage. It is the part that is cheap and unambiguous. +# +# `check_examples_run` is worth a ticket of its own regardless: its only callers +# are its own tests (releaser_preflight/tests.rs), and it fails OPEN — a non-zero +# runtime exit counts as a pass on the grounds that "--help exiting non-zero is +# OK", so a crash passes. +# +# The feature matrix stays out too, and that one is genuinely undefined: +# `cargo-hack` is not installed and nothing in this repository references +# --each-feature, --feature-powerset or any matrix tooling.
