AGENTS.md states the three exposure postures and why the guard chain cannot front a
non-browser client. Infrastructure/Caddy.md gains *Unguard a vhost* — route first,
IdP rows last, audit lists after — since deleting the proxy provider while traffic
still enters :8016 hands browsers authentik's error page. The Audiobookshelf page
retires its two-doors law (the guarded vhost as a browser-only door, remote
listening via VPN) for one address every client carries, adds how a listener gets an
account, and says plainly what the exemption costs.
`abs.` was a three-letter abbreviation of the container; the library it serves is
/mnt/entropy/Audiobooks, and `audiobooks.` says what the door is. Renamed in one
commit on purpose: the pihole seam fails the suite if a Caddyfile vhost has no
addn-hosts record, so any split would leave a red commit, and the `abs` name was
never deployed at the IdP with this fix, so nothing has to keep answering it —
no alias, no redirect, no stale URI.
Moves together: the Caddyfile site block, its matcher (@abs -> @audiobooks), the
LAN record, ABS_EXTRA_BASES in authentik-audiobookshelf-sso.sh (that script
REPLACES the provider's redirect-URI list, so the old origin's callback leaves the
RP when it is next run), the homepage admin tile, the guard spec's GUARDED list and
leak marker, and the three vault pages that name the door. authentik's provider row
follows in the deploy window (external_host + name), which re-derives its
redirect_uris through scripts/authentik-proxy-provider-defaults.sh; the Application
row keeps its own name, "Audiobookshelf Guard" — it names the app, not the vhost.
Step 1 gains the closing sentence the abs-proxy incident demands: the ak-shell
snippet that creates a ProxyProvider with objects.create() must be followed by
scripts/authentik-proxy-provider-defaults.sh, or the guard fails before any
credential. Step 2 gains the forwarded-scheme clause for any app that derives its
own origin from the request. Each fact keeps one owner — the laws stay on
[[Authentik Outpost Reference]] (provisioning rule 3) and [[Audiobookshelf]]; this
page only says where in the procedure they bite. Outpost page timestamp bumped to
match its substantive edit.
Infrastructure/Caddy.md now owns the order of operations for exposing a vhost
(proxy provider + application + embedded-outpost claim, then the route, then the
name and the chain audit), because the IdP row is invisible state that nobody
recreates. Audiobookshelf's Internal-only row and law become Two doors, one app;
the homepage link and index.md follow.
The docs-fact census wave re-read the live hosts and re-keyed every page
it could: runtime/payload identities, ports, sizes, ledger figures, unit
state, and the retirement banners that drifted as the fleet moved. The
wave was interrupted mid-run, so this commit carries only what passed the
integrity gates: every touched page parses (front matter or H1+status
convention intact, balanced fences, no truncated tables, trailing
newline), the docs_completeness and link-integrity seams are green, and
bats is 384/384.
Numbers that this session proved on live hosts are keyed to the measured
value, not the page's earlier claim.
Kestrel rejects the h2c upgrade preface; Caddy surfaced that as a 502 per
request while the backend answered 200 on plain HTTP/1.1 from Caddy's network.
Contrast recorded: Plex PMS needs the TLS transport, Jellyfin needs none.
All in-repo path references (AGENTS.md, README, old scripts, report artifacts,
test code paths) rewritten in the same commit; focused-test map extended for
.gitignore, old/scripts/*, dankclaw/comfyui/*, and report/* per this repo's
own convention ('add one before committing'). Obsidian wikilinks are
title-based and unaffected.
