The gate existed because Petal authenticated nobody and a public hostname
was therefore a public, writable API. It no longer is: every /api route
answers 401 without a session, so the only thing an anonymous visitor
reaches is the app shell and its redirect to Authentik. The separate
unauthenticated /api/health router goes with it — it only existed to escape
the middleware. A second password in front of a real login is one more
thing to lose.
Also records the two problems this deployment actually hit, since both fail
before the login page appears and neither is obvious from the error: the
issuer's trailing slash is significant, and a provider created through the
API rather than the admin UI comes up with an empty grant_types.

Petal is now an OIDC client in its own right rather than trusting a header
from the proxy. The Phase-0 Resolver seam was the only integration point:
main.go picks the session store when Authentik is configured and the static
local user otherwise, and no handler or query moved for either.
internal/auth gains three pieces. session.go issues an opaque cookie token
and stores only its SHA-256, so a database copy yields nothing usable; the
30-day expiry slides on every request, throttled to one write an hour, and
logout deletes the row rather than just the cookie. oidc.go runs the
authorization-code flow with state, nonce and PKCE, and discovers the
provider lazily and on retry — an Authentik outage should block new logins
without stopping Petal booting or invalidating live sessions. users.go
provisions accounts from the token's claims and gates them on an allowlist
that matches emails as well as subject ids, since a subject is an opaque
uuid that doesn't exist until someone has already logged in once.
Migration 0010 lands sessions, images and users.pair_lang together. The
images table closes the capability-URL hole the Phase-0 audit flagged: a
hash was previously enough to fetch anyone's picture. Rows are keyed
(name, user_id) so one file can have several owners and deduplication
survives; a stranger gets 404 rather than 403, the cache header drops to
private, and files already on disk are claimed at startup or every image
already pasted into a document would 404.
On the frontend a single 401 interceptor feeds a warm bilingual sign-in
overlay, drawn over a still-visible editor because nothing has been taken
away. Behind it is the part that matters: a save that comes back 401
stashes its body to localStorage before anything else and stops the
auto-save loop, and reopening that document after signing in merges the
draft back and saves it. An expired session must not cost writing.
Writing the round-trip test against a stub identity provider turned up a
real bug: the one-shot state/nonce/PKCE cookies were cleared in a defer,
which runs after the redirect has written the response header, so the
clearing Set-Cookie was silently dropped and they lingered for their full
ten minutes.
Also swaps the emoji favicon for a drawn sakura, which renders as Petal's
own rose palette everywhere instead of whatever each platform's font
decides, and doubles as the app tile in Authentik.
Migration 0010 verified against a VACUUM INTO copy of the live millenia
database: counts intact, FTS still matching, the one existing image
claimed.

The canonical instance -- the one with her actual writing -- turned out
to be the least protected thing in the estate:
- No scheduled backup at all; the newest snapshot was a month old. Now
petal-backup.timer: VACUUM INTO, gzip, age-encrypt with the parodia
public recipient, push to the VPS over headscale with a size check,
prune both ends. Persistent=true because the box is not on 24/7.
Neither machine can decrypt what it holds; the identity is offline.
- Petal ran as a bare ./petal with PPID 1, so a crash or reboot left it
down until somebody noticed. Now petal.service, verified by kill -9.
- The Piper units retried forever without ever failing: RestartSec=3
against systemd's default 10s window means the burst limit is never
reached, which is how a dead service logged 26,800+ restarts over a
day while read-aloud silently fell back to browser speech.
StartLimitIntervalSec=300 makes a broken Piper show up in --failed.
backup-petal.sh now handles both deployment shapes (compose exec on the
VPS, local binary on millenia) and encrypts before anything leaves the
host. The VPS no longer uses it -- Petal rides parodia-backup there.
Rebinding vllm-chat was the expensive option: Petal, Gogobee and Open
WebUI all point at 127.0.0.1:8000, and Open WebUI keeps its endpoint in
its own database rather than in env, so moving the bind address meant
editing three consumers and reloading a 35B AWQ model. The socat unit
adds a second listener on the headscale address instead -- local callers
untouched, no downtime, and the only new exposure is on the VPN. Bound
to 100.64.0.2 specifically, never 0.0.0.0: the far end is a public host.
Verified: a grammar checkpoint from petal.parodia.dev returns real
suggestions in ~3s over the VPN.
Also documents two things found on millenia that were invisible from
outside it:
- Piper had been dead since the Jul 26 reboot, 26,800+ failed restarts,
with read-aloud silently falling back to browser Web Speech. An OS
upgrade moved /usr/bin/python3 from 3.13 to 3.14, and venv/bin/python3
is a symlink to the system interpreter, so lib/python3.13/site-packages
went invisible -- sys.path had no site-packages at all. Recreating the
venv lands Piper 1.6.0, which is what TTS_PATH exists for.
- The canonical instance has no automated backup (newest snapshot a
month old) and runs unsupervised with PPID 1. Both written down; the
backup one is pending the encryption-at-rest decision.
Backups on the VPS now ride parodia-backup (age-encrypted, offsite, S3),
using VACUUM INTO rather than that script's iterdump helper -- iterdump
does not reproduce an FTS5 virtual table, so a restore would have come
back with cross-document search silently missing.
deploy/README.md becomes the real runbook: the VPS stack, Traefik, the
headscale LLM link, the interim edge gate, backups and restore. The
millenia Piper notes move to an appendix -- that instance still runs
them, and it is still canonical.
Two items are called out as outstanding rather than done, because both
need access to millenia: vLLM is not bound to its headscale interface,
so no AI pass works from the VPS yet, and parodia's ssh key is not
authorized there, so backups are VPS-local only -- which is not a backup
in the sense that matters. Each has its one-command fix written down.
Also folds in DreamDict gaining Spanish: es was explicitly gated on that
dataset existing, so it moves from "Later / not now" to a normal
follow-on pair after pt-PT, and the Phase 20 provider seam should cover
it from the start.
Replace the browser's robotic Web Speech API (espeak on Chromium) as the
primary read-aloud path with server-side Piper neural TTS, served by petal
and kept fully offline on millenia next to Ollama.
- internal/tts: proxy short passages to Piper, transcode WAV -> mp3/opus via
ffmpeg, content-addressed disk cache (instant re-taps). Each Piper instance
loads one voice, so language routes to its own endpoint:{voice}. Unknown
language -> 404 so the client falls back to Web Speech. UTF-8-safe truncation
for multibyte (Chinese) text.
- config: TTS_ENDPOINT / TTS_ENDPOINT_ZH / TTS_VOICE_EN / TTS_VOICE_ZH /
TTS_CACHE_DIR / TTS_TIMEOUT / TTS_AUDIO_FORMAT. Route mounts only when
TTS_ENDPOINT is set; otherwise unchanged behavior.
- web/audio/speech.ts: speak() hits /api/tts first, falls back to Web Speech on
any failure; rapid-tap-safe via a request token. Call sites unchanged.
- deploy/: Piper user systemd units (EN :5005, ZH :5006), setup script, README.
English (en_US-amy-medium) and Chinese (zh_CN-huayan-medium) are both live.
