name: Sync to HuggingFace Space

# hf-sync (Yachay, slsa-l2-promotion 2026-06-03): switched from git-push / orphan
# mirror to huggingface_hub create_commit of README.md only. Prior failures:
# (1) dangling LFS pointer (oid 28f749cf 404s) broke lfs:true checkout/push;
# (2) HF pre-receive hook rejected oversized plain-git design blobs in ancestor
# commits; (3) the upload_folder variant pushed the GitHub README verbatim with
# NO Space front-matter, which CONFIG_ERROR'd the Space. create_commit of a
# front-matter-prepended README needs no git history and no LFS, so it avoids all
# three. Front-matter is base64 (FM_B64) so the python here-doc stays fully
# indented inside the YAML block scalar (the indentation pitfall flagged in sentra).
#
# front-door sync (drift-fix 2026-06-07): the README-only sync let the served
# front-door HTML drift — an edit to pages/console.html / console/index.html on
# GitHub would silently disappear on the next HF factory rebuild (the Space kept
# its own older copy), forcing a manual second push to both repos. The
# "Sync front-door files" step below now mirrors the plain-text front-door files
# (pages/*.html, pages/*.js, console/*.html, console/*.js) to the Space via the
# same git-free create_commit path. It deliberately EXCLUDES the built SPA
# bundles (console/assets/**, console/static/**) — those are large/possibly-LFS
# deployed artifacts that already live on the Space, and re-syncing them would
# reintroduce the LFS/pre-receive failures documented above. Timestamped
# *.bak-* backups are skipped.
#
# front-door deletion sync (drift-fix 2026-06-08): the add/update-only path above
# left a stale copy on the Space whenever a front-door file was DELETED or RENAMED
# on GitHub main — the old page lingered and kept being served after an HF rebuild.
# The step now also diffs the Space's current front-door file list
# (HfApi.list_repo_files, filtered to the same pages/*.{html,js} + console/*.{html,js}
# set) against the local files and emits CommitOperationDelete for any that are gone.
# The same exclusions apply: built SPA bundles (console/assets/**, console/static/**)
# and *.bak-* backups are NEVER deleted.
#
# cathedral front-door coverage (drift-fix 2026-06-10): the redesigned a11oy.net
# hero is served from cathedral.html (repo ROOT) + static/a11oy_cathedral.js, which
# fall OUTSIDE the pages/console glob above — so an edit to either on GitHub main was
# NOT auto-mirrored to the Space and the two copies drifted (they only matched because
# the launch pushed them by hand). Both exact paths are now part of on.push.paths, the
# add/update glob, and the delete-aware is_front_door() set (matched as an EXACT pair,
# NOT a broad static/* glob, so the Space's other static/ vendor blobs are untouched).
