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.
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.
SUGGESTIONS.md (new): the product rationale. Every user gets one
(English + X) pair, X in {zh, pt-PT, fr, maybe es} - bilingual UI in the
pair, type in either language, direction inferred without a detector
(both-dictionaries spellcheck, show-both gloss on collision). Langpacks
keyed by X. LLM-minimalism as a standing principle: the LLM never gates
essential functionality; grammar-lite rules and an embedded
miscollocation list are planned as code-first layers beneath the LLM
families.
MULTIUSER_PLAN.md: all OPEN decisions settled - in-app OIDC (the
parodia.dev VPS hosting plan decides it), 30-day sliding sessions,
allowlist, migration-by-script, image-store ownership fixed alongside
auth, DreamDict imported as a package reading dict.db (module rename
prereq lives in the dreamdict repo), zh stays on ECDICT until compared.
BUILD_PLAN.md: the deferred bucket becomes checkboxed Phases 15-22
(deploy plumbing / OIDC / local-user migration / client-state
namespacing / langpack extraction / DreamDict provider / pt-PT pair /
learning loop + code-first layers) with standing rules: isolation tests
in the same commit as any user-scoped endpoint, LLM-minimalism, and
bilingual aesthetic as acceptance criteria.
Petal ran as a single hardcoded user, with db.LocalUserID named directly
at ~35 query sites. That made the caller's identity a compile-time
constant scattered across every package — nothing a real login could
replace without touching all of them.
New internal/auth moves it into the request context:
- Middleware(Resolver) resolves the caller once per API request
- handlers read auth.UserID(r.Context()) instead of naming a user
- Resolver is the seam an Authentik session check drops into
- StaticResolver(db.LocalUserID) keeps Petal single-user today
Behavior is unchanged. UserID returns "" rather than panicking when the
middleware is absent, so a mis-wired route fails closed: every query is
WHERE user_id = ?, which then matches nothing.
main.go splits /api into a public group (/health, /version) and an
authenticated group for everything else — a monitoring probe must not
need a session.
Two pre-existing access-control gaps fixed while threading, both
harmless with one user and not with two:
- setStatus (accept/dismiss) updated a suggestion by bare id with no
ownership check at all
- listForDoc/fetchPending read a document's suggestions by doc_id
alone; a suggestion quotes the sentence it corrects, so that leaked
the source prose
Both now scope through documents.user_id.
Tests: internal/auth covers the context round-trip, the absent-context
case, and both 401 paths. Two-user isolation suites in docs and
suggestions mount the same routers twice behind two resolvers over one
database and assert a stranger gets 404 on every id-taking path, sees
nothing in list/search, and leaves the owner's data untouched.
Those suites earned their keep immediately: docs.fetch gained a userID
parameter but kept binding db.LocalUserID in the query. Unused
parameters are legal Go, so it compiled clean, vet was silent, and every
existing test passed while the lookup stayed unscoped.
Still global, out of scope and flagged in BUILD_PLAN.md: the image store
has no per-user association, and frontend localStorage keys are
per-browser rather than per-account.
Phase 12 — collocation coach: a third suggestion family for gentle
"natives usually say…" hints on non-native word pairings, reusing the
existing runPass/pendingScope/rail machinery.
- llm/collocation.go (RunCollocation, 25s floor, reuses ParseCheckpoint)
+ collocationSystemPrompt/CollocationMessages (warm, Mandarin gloss,
defers grammar/spelling to the grammar family)
- migration 0005 rebuilds the suggestions table to extend the type CHECK
(SQLite can't ALTER a CHECK)
- collocationScope + CollocationLimit + POST /{id}/collocation
- fix: grammarScope was `type != 'voice'` and would wipe the new
collocation flags; now `type NOT IN ('voice','collocation')`
- frontend: --color-blossom, "Make it sound natural 🌸" pill,
collocating/runCollocation in useCheckpoint, StatusBar dot
Phase 13 — vocabulary garden: capture looked-up words and surface them
for gentle spaced repetition.
- new internal/vocab package: migration 0006 (vocab_words, SM-2-lite
columns, doc_id ON DELETE SET NULL, UNIQUE(user_id,word)),
scheduler.go (Leitner ladder 1/3/7/16/35 then geometric; gentle
"again", no streak-shaming), handlers (capture-upsert/list/due/
review/delete, owner-scoped, SQLite-side datetime math)
- auto-capture on word lookup (dictionary-known words only, captures
the surrounding sentence + doc_id) + 🤍/💚 toggle on WordCard
- GardenPanel: blossom grid (bloom by reps), flashcard review (sentence
blanked, flip, again/good/easy, recognition↔production), sleepy-kitten
footer; opened from a global 🌷 header button
Tests: TestCollocationPassCoexists, vocab scheduler + handlers, db CHECK
extended. go build/vet/test + tsc + vite + vitest (51/51) clean;
migration verified against a copy of the live DB; live backend smoke
walked the full vocab lifecycle + the warm-502 collocation path.

Companion warmth:
- ENCOURAGEMENTS grown 5->10; new BEDTIME lines (warm/playful, zh-first)
- useCompanion heartbeat gains a bedtime branch (>=11pm, while actively
writing) gated by a 30min cooldown; new 'bedtime' BubbleTone paces it
Night mode (auto at ~11pm, local clock):
- lib/night.ts centralizes isBedtime() + the window, shared with the nag
- useNightMode toggles a `petal-night` class on <html>; index.css re-points
only the palette tokens, so every Tailwind color utility flips via var()
with no component edits (600ms dusk fade; print stays white)
- PetalFall gains a `night` prop: chunky cartoon power stars (makeCartoonStar,
5 candy colors) mixed ~70/30 with twinkle sparkles; each star spins at its
own rate (~0.5-2.2 rad/s, random direction), falls straight down, shimmers
Verified: go vet/test, tsc, vitest 51/51, vite build; real-browser
screenshots/video (clock mocked to 23:30).

Writer power-ups (Phase 11), plus the selection-bubble vs copy/paste fix.
- Find & Replace (Ctrl/Cmd+F): SearchHighlight decoration extension +
FindReplace bar (match-case, replace-all back-to-front, scroll without
popping the selection bubble).
- Read-aloud (Web Speech, offline) on the word card and selection bubble.
- Keyboard/touch access to the ESL helpers: Ctrl/Cmd+D look up word at caret,
Ctrl/Cmd+J rewrite selection, touch long-press lookup. Refactored the
right-click handler into a shared openWordLookup(pos).
- Whole-corpus backup: GET /api/docs/export-all zips every doc (md/docx),
de-dupes filenames, dated name; sidebar download links. TestExportAll.
- Smart typography input rules (curly quotes/em-dash/ellipsis), ASCII-only so
CJK is untouched.
- Duplicate doc, sidebar sort (Recent/Title/Longest), toolbar outline popover.
- English phonetic (chosen over pinyin for an English learner): ECDICT-built
phonetic.json.gz (46,579 words) + Result.Phonetic + WordCard IPA line;
scripts/build_phonetic.py (full build + --seed fallback).
- Selection bubble no longer blocks copy/paste: deferred to pointer-up and made
click-through except on its buttons.
Claude-Session: https://claude.ai/code/session_016Yr6jELuRc7hyzYLccQKZd
Cross-document FTS5 search (trigram tokenizer for EN + space-free CJK, kept in
sync by triggers, back-filled from existing docs). GET /api/search uses the FTS
index for queries >=3 runes and a LIKE fallback for 1-2 (so 2-char Chinese words
resolve); snippets are built in Go with rune-aware boundaries and sentinel
highlights.
Tags: user-scoped tags + document_tags join (both cascade), idempotent
create/assign, per-tag doc counts. Doc list and search carry each doc's tags
(one tagsByDoc query). Frontend: useTags, TagChip/TagPicker/SearchBox, rewritten
DocList with chips + filter bar + search.
Tablet/touch: responsive sidebar drawer (hamburger + scrim <768px), coarse-
pointer tap targets, tap-to-open + outside-pointerdown-close for suggestion
cards.
Warm LLM-down state: useCheckpoint llmDown flag drives a gentle bilingual
StatusBar note (writing still saves locally).
Migration 0004 (tags + FTS). Tests: tags lifecycle, search EN/CJK/LIKE/update-
reindex. go build/vet/test, tsc, vite all clean; verified live on deployment host.

Inline Chinese gloss (offline) and a "say it more naturally" / tone-rewrite,
the two ESL features for the Mandarin-speaking writer.
Gloss: embedded English→Chinese dictionary (gloss.json.gz, 57k common words
built from ECDICT via scripts/build_gloss.py). lexicon gains Gloss()/Result.Gloss
and a lightweight GET /api/gloss/{word}; the right-click WordCard leads with the
中文; GlossTip shows it on a 350ms hover (reuses wordAt, so CJK is never glossed).
Offline + instant, works with the LLM down.
Rewrite: selecting text pops a SelectionBubble (✨更自然 + the tone vocabulary);
picking a style calls POST /api/docs/:id/rewrite (llm.RunRewrite, stateless,
owner-scoped) and shows a RewritePreview (original→rewrite, accept/cancel/retry).
Accept applies it in-editor.
Tests added in lexicon and suggestions. go build/vet/test, tsc, vite all clean;
live smoke vs a fake vLLM verified gloss + rewrite + 400/404/502 paths.
Claude-Session: https://claude.ai/code/session_016Yr6jELuRc7hyzYLccQKZd
Version history: new document_versions table (migration 0003) holding
full-body snapshots that cascade with the doc. Throttled auto-snapshots
on save (>=3min apart, max 40/doc, pruned), explicit manual restore
points, and a pre_restore safety copy taken before each restore so
restoring is itself undoable. Endpoints under /api/docs/:id/versions,
all owner-scoped. Empties and bare renames never snapshot.
Export: pure-Go Tiptap-JSON -> Markdown / HTML / plain-text / docx
(no cgo/pandoc, single-binary intact), CJK-safe with RFC 5987
filenames. docx is a hand-built OOXML zip. PDF is handled client-side
via the browser print dialog + an @media print stylesheet so CJK
renders with the reader's own fonts.
Frontend: ExportMenu (downloads + Print/PDF) and HistoryPanel
(snapshot list, preview, restore) wired into the title row; bilingual
zh-first to match chrome. Restore remounts the editor via editorEpoch.
Stop saving empty docs: blank Untitled drafts now reuse-on-create and
self-discard when navigated away from (refs avoid stale closures).
Tests: versions_test.go, export_test.go (incl. valid-zip docx).
go build/vet/test, tsc, vite build all clean; live end-to-end smoke
verified snapshot/throttle/restore/export.

Vendored Hunspell en.aff/en.dic into web/public/dictionaries/en/ (served as a
static asset + embedded in the binary, kept out of the JS bundle). dictionary-en
moved to a devDep — only used to source the files.
- useSpellChecker (App-level, loads once/session): fetches the dict, builds an
nspell instance, replays a localStorage personal word list; addWord persists
and bumps a version so consumers re-decorate. Ambient types in
src/types/nspell.d.ts (the package ships none).
- SpellCheck Tiptap extension: misspellings as ProseMirror decorations (no
stored marks), recomputed on edit / caret move / checker swap. Latin-only
tokenizer so CJK is never flagged; skips short tokens + all-caps acronyms;
exempts the caret word to avoid mid-typing jitter. Reuses mapOffset (now
exported from SuggestionHighlight); wordAt resolves the exact span on click.
- MisspellCard: soft rose wavy underline, bilingual popover with up to 5 nspell
corrections (click to replace) + add-to-dictionary. Closes on outside-pointer,
edit, or doc switch.
Chinese spell check intentionally omitted — nspell is dictionary-based and
English-only; Chinese typos (homophone 别字) need an LLM, out of v1 scope.
tsc/vite/go build+vet clean; live server serves both dict files; nspell
behavior smoke-tested.

Click the mascot to open a bilingual picker and switch between the Sleepy Cat
(always asleep, still talks in her sleep) and the Happy Dog (awake/bouncy).
Choice persists in localStorage.
- companions.ts is the roster; add one by dropping a pure-vector Lottie JSON
in animations/ and appending a COMPANIONS entry.
- napping = companion.alwaysAsleep || mood === 'sleeping' drives the sway/zzz.
- Removed the old single MOOD_ANIMATIONS map (animations/index.ts).
Claude-Session: https://claude.ai/code/session_016Yr6jELuRc7hyzYLccQKZd
- LottiePlayer now auto-crops each asset to its content bbox (union getBBox
across 6 frames -> square viewBox), so stock files with empty artboard
padding fill the badge instead of floating tiny in the middle.
- Wire sleeping-cat.json to every mood: she's always asleep in the corner yet
still mumbles tips and cheers through the bubble. napping hardcoded true so
she keeps the calm sway + drifting zzz even while "talking".
- happy-dog.json parked in the folder as an awake-mascot alternate.
- Enable resolveJsonModule for the JSON imports.

A cozy bottom-right mascot that reacts to the writing session: cheers on
accepted suggestions and word-count milestones, drops Mandarin-first writing
tips, suggests screen breaks after long stretches, and naps when idle.
- useCompanion: library-agnostic behavior engine (priority + cooldown paced
so it never nags); tips.ts holds all copy, bilingual zh-first.
- LottiePlayer wraps lottie-web's light build (offline, no eval/CDN) so it
bundles into the Go binary. Ships with an emoji-kitten placeholder per mood;
dropping a Lottie cat JSON into animations/index.ts is the only swap needed.
- Speech bubble uses the CJK-first font stack (spec Note #17).
Claude-Session: https://claude.ai/code/session_016Yr6jELuRc7hyzYLccQKZd
- Accept confetti: CSS-only 4-dot burst spawned at the accepted card,
trajectory via inline --dx/--dy, auto-cleared after 720ms.
- Distraction-free mode: editor focus collapses the doc-list sidebar
(width→0 slide), canvas re-centers full-width; Escape or a click
outside the canvas (header/gutter/status bar) restores it.

Tier-1 voice-consistency pass: whole-document LLM review surfacing passages
that read tonally out of place (formal/over-polished/paraphrased-too-closely),
as honey-decorated `voice` flags with no correction (awareness-only).
- internal/llm/voice.go: RunVoice sends the whole document (no TruncateDoc),
MaxTokens 2048, 20s per-doc floor (VoiceInterval). Standalone voice prompt
in prompts.go (not bundled with the grammar checkpoint, per spec).
- internal/suggestions: POST /api/docs/:id/voice. replacePending is now
family-scoped (pendingScope) so grammar and voice never clobber each other's
pending flags; both passes return the unified pending set. check/voice share
one runPass helper. TestVoicePassCoexists covers both directions.
- Frontend: api.voiceDoc, useCheckpoint voicing/runVoice, honey "Check my
voice" toolbar pill, breathing honey dot in StatusBar.

Conversational follow-up on a suggestion, streamed token-by-token.
Backend (interface-only; handlers never touch a concrete LLM client):
- internal/llm/chat.go: StreamAskPetal with conversational sampling
(max_tokens 512, temp 0.7, rep 1.15, top_p 0.92, stop "\n\n\n"),
reusing AskPetalSystemPrompt + TrimHistory.
- internal/suggestions/chat.go: POST /api/suggestions/:id/chat. One
user-scoped join loads the suggestion + parent content_text;
surroundingParagraph extracts the \n\n-bounded paragraph at from_pos
(whole-doc fallback when unlocated) and injects it server-side.
Streams event: token / event: done SSE frames with JSON-encoded data
so token newlines can't break framing; real http.Flusher per chunk.
LLM-unreachable -> 502 before SSE headers; unknown suggestion -> 404.
Frontend:
- streamSuggestionChat: fetch + ReadableStream SSE parser (not
EventSource, needs POST), abortable.
- AskPetal.tsx: whole conversation in component state (no persistence,
cleared on close), Petal's first bubble pre-seeded with the
explanation, rose/lavender bubbles, CJK font stack on the bubbles
only (Note #17), streaming caret.
- SuggestionCard "Ask Petal" pill pins the card open while chatting
(hover-close suppressed, click-away closes) and widens it to 340px.
Tests: chat_test.go covers streamed-text concat + done event,
server-side context injection on the system message, sampling params,
404, and surroundingParagraph. go build/vet/test clean, tsc clean,
vite build OK. Live SSE smoke-tested against a fake streaming vLLM:
tokens flushed individually through the chi middleware stack, done
terminator, 502 on LLM-down, 404 on unknown suggestion.

Qwen 3.5 — the spec's recommended model — is a reasoning model. With
thinking on, Ollama streams its chain-of-thought into a separate
`thinking` field and hits num_predict before emitting any answer into
`content`, so Complete() got an empty string and the checkpoint failed
with "no JSON object in model output". Sending `"think": false` on every
/api/chat request fixes it; non-thinking models (qwen2.5) ignore the flag.
Validated end-to-end on deployment hardware (Ollama, qwen3.5:9b): the
grammar checkpoint now caught all five ESL errors in a 3-sentence sample
with correct JSON and string-anchoring, ~8.5s warm.
Claude-Session: https://claude.ai/code/session_016Yr6jELuRc7hyzYLccQKZd
Backend (internal/llm): backend-agnostic LLMClient interface + factory
with vLLM (OpenAI-compat) and Ollama (native) clients, each Complete +
Stream. prompts.go holds the checkpoint and Ask Petal templates;
checkpoint.go salvages JSON from model output (brace-matched), enforces a
per-doc 30s RateLimiter, and truncates the doc to a latency cap.
internal/suggestions: POST /api/docs/:id/check runs a checkpoint and
replaces the doc's pending suggestions in one tx (accepted/rejected kept
as history); GET /api/docs/:id/suggestions lists pending;
POST /api/suggestions/:id/{accept,dismiss} resolves one. Throttled checks
return the current set rather than erroring.
Frontend: useCheckpoint (4s debounce, loads existing on open, stale-guard
tokens); SuggestionHighlight renders ProseMirror decorations re-anchored
by the `original` string on every doc change (not stored marks), with
precise textblock-offset→PM-position mapping; SuggestionCard shows the
type tag + diff + explanation and applies the replacement in-editor on
accept; breathing rose checkpoint dot in the StatusBar; fade-float +
breathe animations.
Tests: llm parse/rate-limit/truncate; suggestions full flow + rate-limit
over httptest with a stub client. Smoke-tested end-to-end against a fake
vLLM endpoint (anchoring verified) and the LLM-unreachable 502 path.

Backend internal/docs: chi sub-router (list/create/get/update/delete)
mounted at /api/docs, scoped to the local user. Create uses RETURNING;
update is a COALESCE partial-update so rename and full editor save share
one PUT. JSON 404/400 errors; handlers_test.go walks the lifecycle.
Frontend: api/client.ts, useAutoSave (1.5s debounce + saveNow flush
before doc switch), EditorCore (Tiptap StarterKit/Underline/TextAlign/
Placeholder/CharacterCount) + Toolbar, DocList/DocListItem, StatusBar,
and an App.tsx that orchestrates load/select/create/delete with
optimistic sidebar patching. content + content_text + word_count are
emitted together on every edit. .petal-prose styling (Lora body, Nunito
headings).
Verified: tsc clean, vite build, go build, full CRUD smoke test incl.
CJK title round-trip and SPA serve.
