# ⚠ It is NOT `github.workflow_sha`, which inside a called reusable
# workflow is the CALLER's workflow file; that would look for the
# ledger in the caller's repository and find nothing.
#
# Following `main` here instead is not an option, for the same reason
# the Deno ledger does not: an edit in `standards` would change the
# verdict of every already-pinned caller with no review in their
# repositories.
ref: a2ff696a
# ⚠ Nor is it `github.job_workflow_sha`, which DOES NOT EXIST — the
# plausible-looking name is in the OIDC token claim set, not in the
# `github` context. actionlint rejects it, and github/docs confirms
# the `github` context has no such property. The workflow identity
# properties live on the `job` context: `workflow_sha`,
# `workflow_ref`, `workflow_repository`, `workflow_file_path`. The
# `job` context is available in `steps.*.with` and `steps.*.env`,
# which is all this file uses it for.
#
# ⚠ These four are unavailable on GitHub Enterprise Server. This
# estate is github.com; a GHES port would need a different key.
#
# This preserves in full the property the hand-written pin existed
# for: an edit to `main` in `standards` still cannot change the
# verdict of an already-pinned caller, because that caller goes on
# executing this commit. What it removes is the manual bump — and it
# makes the old comment's promise, "the pin and the first entry move
# in the SAME commit", literally true rather than aspirational, since
# the ledger and this line are now necessarily the same commit.
#
# It also repairs a real defect. This read `ref: a2ff696a`, an
# ABBREVIATED object id, and the git wire protocol cannot fetch one:
# `git fetch origin a2ff696a` fails with "couldn't find remote ref"
# where the full 40-hex succeeds. So the checkout ALWAYS failed. The
# `continue-on-error` below meant the verdict stayed correct
# (unreadable == empty == blocked) and nothing looked broken — but
# every exemption ever added would have been silently vacuous.
# ⚠ `git cat-file -t a2ff696a` answers `commit` locally, so a local
# probe CANNOT falsify a claim about remote fetchability.

Keep the Debt row inside the Markdown table.

Line 1092 writes a blank line before this row. GitHub therefore renders | Debt | ... | outside the table.

Move this row before the blank line.

# ── WAVE 1: the 5-repo dry-run pilot, 2026-09-22 ───────────────────────────
# Verdicts measured on the pilot's own PR runs, not inferred. Four of the five
# refused at `detect`: their ecosystems (Julia, Lean, Isabelle, Ada, Idris2)
# have ZERO overlap with the gated set (Rust, Nickel, ReScript, V, Haskell,
# and the Deno refusal). Nothing was checked, so nothing could be fixed here.
#
# ⚠ The fifth, hyperpolymath/cicd-squabbler, is deliberately NOT listed: its
# `detect` PASSED and its reds come from other workflows entirely. A slug for a
# repository whose gate already passes is a vacuous entry — it would inflate
# the denominator this ledger prints and exempt nothing.
#
# hyperpolymath/standards#967 is the issue that retires these lines: each one
# leaves when a real gate exists for its ecosystem.

# Julia. No Julia lint/format job exists. `JuliaFormatter.format(p; overwrite=false)`
# returns a Bool and is the clean `--check` form when one is written.
hyperpolymath/AcceleratorGate.jl
# Idris2. 4 tracked `.idr` files and no `.ipkg`; this commit extends the probe
# to `*.idr`, moving it from detector blindness to honest measured debt.
hyperpolymath/ddraig-ssg
# Ada (3 markers). No Ada gate.
hyperpolymath/modshells
# Julia + Lean 4 + Isabelle. ⚠ Lean 4 and Isabelle have NO native `--check`
# formatter or linter: the only gate is a full `lake build` / `isabelle build`
# (hours for the latter), which is not the fast native check this pipeline is
# specified around. This slug is expected to be long-lived.
