From 51d75c023440726e60a559886155a13d095a327d Mon Sep 17 00:00:00 2001 From: hyperpolymath <6759885+hyperpolymath@users.noreply.github.com> Date: Sat, 10 Oct 2026 09:39:33 +0000 Subject: [PATCH 1/2] fix(ci): document Julia nightly exemption for #111 Both Julia nightly checks (ci.yml julia-nightly, julia-test.yml test-nightly) are red on main. This is expected: nightly is an upstream moving target and both jobs already use continue-on-error: true per the Julia ecosystem convention. Determination per standing rule (standards#994, AC1): accepted with documented exemption. The exemption rationale is in the workflow comments and in docs/investigation/2026-10-10-issue-111-nightly-triage/. Closes #111.

Axiom.jl's test suite is substantial (841-line `runtests.jl` ++ 13 included test files covering tensors, layers, serving APIs, interop, +verification, Aqua, JET, and more). Any upstream change to: + +* `LinearAlgebra` internals (used by `qr`, normalization, adjoint) +* `Zygote` adjoint plumbing (the package is a hard dep, pinned `0.6, 0.7`) +* `HTTP.jl` / `JSON.jl` compatibility surfaces +* Base Julia `ccall`/`Libdl` semantics (used by the Zig FFI and crypto shim) + +can cause a nightly-only failure that is *not* a bug in Axiom.jl itself. + +=== Why this is expected and normal + +The Julia ecosystem's standard practice is: + +1. *Required gates* run on Julia LTS (`1.10`) and stable (`1` / `1.11`). +2. *Nightly* runs are informational-only (`continue-on-error: true`) and + exist to provide early warning of upcoming breakage. +3. Nightly breakage is *expected* during Julia's development cycle and is + *not* treated as a defect in the downstream package until the breaking + change lands in a stable release. + +Axiom.jl's configuration follows this convention exactly. The real +compatibility gates are: + +* `julia-compat` (ci.yml): Julia 1.10 + 1.11 × 3 OSes — *all green* +* `test` (julia-test.yml): Julia 1.10 + 1 (stable), crypto-enabled — *all green* + +=== Why fixing nightly is not the right action now + +1. Nightly breakage is *upstream noise*, not an Axiom.jl defect. Fixing it + would mean chasing an unstable target that changes daily. +2. Any "fix" applied today may break again tomorrow when nightly changes. +3. The estate's REPO-STANDARD-MUST-INTEND-LIKE.adoc (§Performance, §MUST) + requires regression protection against *stable baselines*, not moving + nightly targets. +4. The ULTRAPLAN decision fork (Julia matrix) already settled this: + "`1.10 LTS floor + `1` stable + nightly(non-blocking)`" — nightly is + explicitly non-blocking by design. + +== Recommended resolution: *Accept with documented exemption* + +=== Determination + +Both checks are **accepted with a documented exemption**. + +The exemption is: + +[quote] +Julia nightly checks are informational-only. They run with +`continue-on-error: true` and never block merges. Nightly breakage is +expected during Julia's development cycle and does not indicate an +Axiom.jl defect. The real compatibility gates are Julia 1.10 (LTS) and +Julia 1 (stable), which are required checks and must remain green. + +=== What "accept" means under the standing rule + +The standing rule (standards#994, AC1) requires one of three determinations: + +* **Fix** — the check is green on `main`, and the fix is in the repo. + ❌ Not applicable: nightly is an upstream moving target. +* **Retire** — the check is removed. + ❌ Not appropriate: nightly provides early-warning value. +* **Accept with a documented exemption** — ✅ *This is the correct + determination*. The exemption is written down (this document), and the + check remains in place with `continue-on-error: true`. + +=== What "accept" does NOT mean + +Per AC5 (standards#994): + +> No class is closed by adding `continue-on-error`, by demoting a failure +> to a warning, or by dropping the check from the required set without +> AC1's determination. Repair or retire; never mute. + +The `continue-on-error: true` was already present from the workflow's +authoring — it is not being *added* to close this issue.
