Bernd Rodler 62b0455388 feat(ai): OpenCode provider management (B4) — "any LLM OpenCode supports", from inside VNCmail+
Before this, the OpenCode class could only use providers already authenticated
via its own CLI (opencode auth login) — this app could pick a MODEL, never add
a PROVIDER. That is the one thing standing between "OpenCode integration" and
the actual ask: any LLM it supports, added from here.

New GET/PUT/DELETE /api/ai/opencode/providers, backed by GET /provider (every
provider OpenCode knows — 180 on a real run) and GET /provider/auth (which
auth method each accepts). New "Manage providers" panel in the OpenCode
settings section: search, add a key, remove one.

Scoped to API-key auth only, deliberately — recorded in lib/ai/opencode.ts's
module comment. `PUT /auth/{id}` with `{type:'api', key}` is one HTTP call
with a schema-verified shape. OAuth entries in /provider/auth need a browser
redirect + callback this app has no page for, and some carry interactive
prompts beyond a single form (GitHub Copilot's deployment-type picker) — real
scope for later, not something to half-build. OAuth-only providers are still
LISTED, just marked "Browser sign-in only" rather than hidden, so the picker
stays honest about what it can't do here.

A real finding from testing this against opencode's actual behaviour rather
than trusting a 200: NOT EVERY PROVIDER BECOMES CONNECTED FROM A BARE API KEY.
Snowflake Cortex needs SNOWFLAKE_ACCOUNT alongside its token; a single key
field silently leaves it stored-but-unconnected with no error from the PUT
itself. Worse, the provider's own `env` array length does not predict this —
Azure also needs two env vars and DOES connect from one key. There is no
reliable way to know in advance, so the route now VERIFIES by re-listing
providers after the write and reports plainly when a key was accepted but the
provider still isn't connected, rather than reporting the PUT's own success.

Verified live end-to-end, twice: once confirming a simple single-field
provider connects and can be removed cleanly, once confirming the honest
"stored but not connected" case is real and detected, not theoretical.
Cleaned up every throwaway credential from this machine's real opencode
config afterwards (checked auth.json directly, not just this app's view of it).

17 new/updated unit tests. Gate: tsc clean, eslint clean, 2527/2527 tests, build clean.

Bernd Rodler bd778adf12 feat(electron): supervise a password-protected opencode server (B1+B3)
B1 — LIFECYCLE. The OpenCode class previously required the user to remember
to run `opencode serve` in a terminal before opening their mail app, and again
after every reboot; in practice that means the feature quietly stops existing.
The desktop shell now owns it: finds the binary (OPENCODE_BIN, then
~/.opencode/bin — its installer's default, which is NOT on the PATH a macOS
GUI app inherits, so PATH alone finds nothing for most users), starts it on a
free port, restarts up to 3 times if it dies, and kills it on quit. Absent
binary = the class simply stays unavailable, no error.

B3 — SECURITY. opencode's own startup warns "OPENCODE_SERVER_PASSWORD is not
set; server is unsecured" — without one, any local process can drive the
agent. A per-launch password is now always generated (never persisted: the
server dies with the app, so a durable secret would be pure liability) and
handed to the standalone server alongside the base URL.

The auth scheme is worth recording because it is NOT in opencode's own
OpenAPI spec, which declares no securitySchemes at all: HTTP Basic with the
username EXACTLY `opencode`. Verified against 1.18.14 by trying them — an
empty username, an arbitrary one, Bearer, and every plausible custom header
all 401 with the correct password. Pinned by a unit test that decodes the
header, so a future refactor can't silently drop it.

Verified live against a real password-protected server on 4097: authenticated
discovery + prompt round-tripped, AND the same call with no password was
rejected — proving the auth is real rather than decorative.

Also removed now-stale guidance: the 503 no longer says "start one with
opencode serve", because the app does that; it says to install the CLI.

Gate: tsc clean, eslint clean, build clean, 2521/2522 tests. The one failure
is lib/__tests__/jmap-client-resilience.test.ts's onConnectionChange timing
flake — byte-identical to what is already running in prod (git diff vs
origin/main for that file and lib/jmap/ is empty), pre-existing, and
unrelated to anything here.

Bernd Rodler 87336981d3 feat(mail-index): 1-year retention by default + a recency retrieval leg
The two things that made real questions fail against a correctly-populated
index, both fixed at the root.

RETENTION (A1). `INDEX_WINDOW_DAYS = 30` was not merely a fetch bound — catch-up
also PRUNED mail older than it, so "summarise everything from July" was
unanswerable in August because the rows had been deleted, while the UI said
only that nothing matched. Now a user-visible setting (Settings → About &
Data): 30 days / 3 months / 1 year / everything, defaulting to 1 YEAR per the
product owner. The window bounds the fetch AND the prune from one value so the
two can never disagree and delete what was just written; "everything" skips
pruning entirely rather than falling back to some default bound. The per-pass
ceiling scales with the window (500/30d, hard cap 20k) because 500 messages is
right for a month and nonsense for "everything". Email/query now omits the
`after` filter entirely when unbounded — Stalwart rejects a malformed filter
rather than treating `undefined` as unset.

RECENCY (A2). Keyword search structurally cannot answer a question about WHEN:
bm25 ranks by term overlap, so "who sent the last email" matches documents
containing the word "last", and "all mails in July" matches documents
containing "July" — not documents dated in July. Both were asked by a real
user and both failed. New lib/mail-index/recency.ts detects time intent
(English + German, since the UI ships German) and turns it into a date RANGE;
new MailIndex.recent() answers it with an ordered scan over the already-indexed
`occurred_at`. The route ADDS these hits to the keyword hits rather than
replacing them — "what did the last mail from Anna say" is both kinds of
question at once.

Timezone subtlety worth knowing: bounds are built from LOCAL calendar
boundaries and serialised as UTC instants, so "July" covers the user's July.
A mail at 00:30 local on 1 July belongs to it even though its stored UTC
timestamp reads 30 June. My first test asserted the ISO string prefix, which
would have enshrined the opposite and passed only in UTC — the tests now
assert the local-time property instead.

SCOPE, stated by the product owner and now enforced structurally: the
assistant only ever sees the mailbox the user is signed in to. Both retrieval
legs resolve the active account (local leg by cookie slot, server leg by the
session's own JMAP account); there is deliberately no fan-out across connected
or shared mailboxes, and adding one would be a policy change, not a feature.

Gate: tsc clean, eslint clean, 2520/2520 tests (8 new for recency intent), build clean.

Bernd Rodler 98dcd3b1e9 feat(ai): OpenCode provider class; fix retrieval reading the wrong account's index
Three things, all from running the real thing rather than trusting a status code.

1. OpenCode as a 4th AI class (lib/ai/opencode.ts + app/api/ai/opencode/*).
   A locally-running `opencode serve` — the same runtime Paperclip drives as
   an adapter. Its appeal over a BYOK profile is precisely what was broken
   before: opencode owns provider auth itself, so there is NO api key for
   this app to hold, and it reports a REAL model list (25 on this machine)
   instead of asking the user to type an exact provider-specific model id
   from memory. Typing "Sonnet 5" into a free-text box and getting a bare
   "Provider returned 401" is the failure this removes.

   IMPORTANT trap, documented in the module header and pinned by a test:
   opencode is NOT OpenAI-compatible. `/v1/models` and `/v1/chat/completions`
   both answer 200 — because a web-UI catch-all serves index.html for ANY
   unknown path. I built the first version against that assumed compatibility
   on the strength of two 200s and had to throw it away once I read a body.
   Every probe now validates the parsed shape and content-type, never the
   status alone. The real API is GET /api/model + POST /session +
   POST /session/{id}/message, and the reply's `reasoning` parts are stripped
   so a model's private chain of thought can never surface as the answer.

   Proxied through our own backend (like the `server` class) because the
   desktop renderer's origin is a random port that changes every launch;
   same-origin sidesteps opencode's CORS allowlist entirely. Loopback-only by
   construction: a non-loopback OPENCODE_BASE_URL is refused, since "local,
   no keys, nothing leaves the device" is the whole point of this class.

2. Retrieval read the WRONG ACCOUNT'S index. The indexer writes under the
   active account's cookie slot (catchUpIndex passes it) but fetchLocalLeg
   omitted `?slot=`, so search resolved to whichever account the multi-slot
   resolver found first. Single-account installs never noticed; a real
   multi-account/shared-mailbox setup reads an empty store every time. Both
   call sites now pass the active slot.

3. "No local mail index available in this session" was shown even when the
   index existed and simply matched nothing — actively misleading, and it
   masked the missing-SESSION_SECRET bug for hours. AskResult now carries
   retrievalState ('augmented' | 'no-match' | 'no-index') and the two cases
   get different words: build the index, versus rephrase (with the honest
   caveat that keyword search answers content questions better than recency
   ones like "the last mail").

Verified live against real opencode 1.18.14: discovery found 25 models and a
real prompt round-tripped the exact expected answer through the real helper
code, not curl. Gate: tsc clean, eslint clean, 2512/2512 unit tests (10 new,
incl. one that fails if the HTML catch-all is ever accepted as an API), build clean.

Bernd Rodler 2dc224e882 feat(ai): local LLM auto-discovery — find a running Ollama, suggest connecting
New lib/ai/local-discovery.ts: one /api/tags query against the loopback
addresses Ollama binds to (127.0.0.1/localhost), no follow-up /api/show
round trips needed — the tags response already carries capabilities, size,
and parameter_size, enough to recommend a default model. Picks the
smallest non-"thinking" chat-capable model for the fastest first response
("Connect" pre-fills provider+baseUrl+model in one click), and separately
surfaces the largest as a "higher quality" alternative.

New banner in ai-assistant-settings.tsx: fires when Local isn't yet
configured, offers one-click Connect or a persisted "Not now" dismissal.

13 new unit tests using this machine's actual Ollama /api/tags response
(11 real installed models — qwen2.5:32b, llama3.2, deepseek-r1 x2,
gemma4 x3, hermes3, qwen3, qwen3.5, nomic-embed-text) as literal fixtures,
per the explicit instruction to use this machine as the test case:
confirms exactly one query is required, the heuristic recommends
llama3.2:latest (fastest) / qwen2.5:32b (largest) on this real fleet,
never recommends an embedding-only model, and degrades correctly when a
candidate base URL is unreachable.

Full QA gate: tsc clean, eslint clean, 2498/2498 tests passing, build clean.
Also live-verified in a real browser session against this machine's real
Ollama — the banner rendered with exactly these two model names.

Bernd Rodler 30e5059b94 feat(admin): build the AI Policy console (§6) — approved, spec now implemented
New admin tab "AI" (app/(main)/admin/_tabs/ai-policy.tsx): provider-class
toggles, server model allow-list, BYOK provider allow-list, seats/usage
(front-end for the already-real lib/ai/entitlement.ts), retrieval on/off,
consent text + version bump.

Real backend, not cosmetic: AiConsoleConfig persisted via config-manager
(lib/ai/types.ts, ai-policy.json in the CONFIG dir). New GET/PUT
/api/admin/ai/policy. Enforcement wired at every real chokepoint, not just
the picker: /api/ai/server/chat checks classesEnabled.server and the model
allow-list, /api/ai/retrieve checks retrievalEnabled, /api/ai/server/models
filters by allow-list. GET /api/ai/policy folds classesEnabled into the
classes list clients see.

Resolved the spec's 3 open questions as recommended: BYOK allow-list stays
client-side/advisory (wired into ai-assistant-settings.tsx's addProfile),
tier picker stays cosmetic, master aiAssistantEnabled toggle stays in the
existing Policy tab (this tab links to it instead of duplicating it).

Defaults preserve today's behavior exactly (classesEnabled/allowlists all
start empty/null) — turning this on changes nothing until an admin touches it.

Bernd Rodler 91b282d746 feat(ai): real retrieval — SourceRef, RRF fusion, real embedding leg (P3/P4)
Full retrieval pipeline per docs/AI-ASSISTANT-CONCEPT.md §7/§8.1, real end
to end, not mocked:

- lib/ai/retrieval/types.ts: SourceRef + RetrieverAdapter schema. Nothing
  past this file needs to know what a mailbox is - fusion, hydration and
  citation rendering all operate on SourceRef, so adding another product
  later (VNCtalk, the doc's P7) is one more adapter, not a rewrite.
- lib/ai/retrieval/fusion.ts: Reciprocal Rank Fusion, score = Σ1/(k+rank),
  k=60. Deliberately excludes collectionId from the fusion identity - a
  JMAP email can live in more than one mailbox, and the two legs can
  legitimately disagree on which is "primary" for the same message;
  itemId is the real identity. 5 unit tests, including that exact
  double-count case.
- lib/ai/retrieval/mail-embeddings.ts: the server embedding leg. Real
  JMAP Email/query+Email/get (server-side, via the session's own
  auth - see the getStalwartCredentials fix below), real embeddings via
  Ollama's /api/embed (nomic-embed-text), real cosine similarity ranking.
  In-memory cache per account with a 5-minute TTL, not a persistent
  vector store - that's real follow-up work (the doc's own P4), not a
  same-night stretch goal on top of everything else built tonight.
- app/api/ai/retrieve/route.ts: wires it together. ACL note: only ever
  searches the authenticated session's own account - there's no
  shared-mailbox fan-out to pre-filter yet since group accounts are still
  deferred entirely, so nothing here can leak across accounts because
  nothing crosses the account boundary in the first place.
- lib/ai/local-client.ts: retrieveContext() now runs both legs
  (app/api/offline/search's local FTS + the new server embedding leg) in
  parallel and RRF-fuses them, same as before if only one leg is present.

Also, while verifying live: found and fixed embedding-only models
(nomic-embed-text) leaking into the *chat* model picker for both `local`
and `server` classes - Ollama lists them in the same /api/tags response,
but calling /api/chat with one fails outright. Filtered by `capabilities`
(fails open if absent, for older Ollama).

Verified live, for real: pulled nomic-embed-text, logged in via the real
(non-demo) auth flow, asked "When is check-in for the Villa sul Lago
booking?" against the seeded mock inbox - got back "Check-in ... is
scheduled for Saturday 28 March from 15:00 [1]" with 6 real ranked
citations, [1] correctly pointing at the actual booking confirmation
email. Real semantic retrieval finding the right email and citing it
correctly, not a canned response.

Also fixed two pre-existing, unrelated test failures found while running
the full suite for the first time in a while (confirmed via diff against
origin/main - neither touched by anything built tonight; neither pipeline's
CI runs the full vitest suite, only test:translations, which is how these
went uncaught): lib/__tests__/builtin-themes.test.ts hardcoded "exactly 6"
themes and asserted every theme's author is 'Built-in', both stale since
VNClagoon/SRC (author: 'VNC') were added this week bringing the real count
to 8. Left the also-pre-existing, timing-sensitive
jmap-client-resilience.test.ts flake unfixed - out of scope, needs its own
investigation, not a quick correct fix.

Full suite: typecheck clean, lint clean, translations 48/48, production
build succeeds, 2486/2486 vitest (previously 2481/2481 + 2 pre-existing
failures + the new fusion/entitlement tests).

Bernd Rodler dda7adf565 feat(ai): multi-key BYOK, real server class, real entitlement enforcement
Three pieces built together tonight since they're naturally linked (the
server-class proxy is the real entitlement enforcement chokepoint):

1. Multi-key BYOK (public class): several named provider profiles
   (name/baseUrl/model), each with its own key in lib/ai/key-store.ts
   (keyed by profile id, not a single fixed 'public' slot). The "Try it"
   pane lets you pick which saved profile answers each question - not one
   fixed default.

2. `server` class, real: app/api/ai/server/{models,chat} proxy through
   this app's own backend to AI_SERVER_BASE_URL - same-origin from the
   browser, no CORS/OLLAMA_ORIGINS story at all, standing in tonight for
   VNC's EU/CH-hosted infra with the real Ollama on this Mac (swapping to
   the real instance tomorrow is a config change).

3. Real entitlement enforcement (lib/ai/entitlement.ts), scoped to `server`
   only (not local/public, per the 2026-08-05 decisions): checkAndAssignSeat()
   re-validates on every /api/ai/server/chat call - first use auto-assigns a
   seat if any remain, further calls from an unlicensed user get a 402 with
   a specific reason. recordUsage() appends to an append-only metering
   ledger (timestamp/user/model/tokens/latency) that IS the billing record.
   Admin data endpoints at /api/admin/ai/entitlement (seat total, revoke) -
   the visual admin console is a separate, not-yet-built task.

Two real bugs found and fixed during verification, not just claimed fixed:
- /api/ai/policy never actually added 'server' to entitlement.classes even
  when AI_SERVER_BASE_URL was set (only the type comment was updated) - the
  Server radio option silently never appeared until this was caught live.
- The new routes used readStalwartAuthContext(0) (hardcoded slot, SSO/reauth-
  specific) instead of getStalwartCredentials() (the general multi-slot
  session resolver every other authenticated route uses) - reachable but
  wrong, and would have hidden a real auth gap behind "works on my slot".

Verified end-to-end for real: built + ran the actual server, logged in via
the real (non-demo) auth flow, selected Server, listed the real Ollama
models through the proxy, asked "Reply with exactly the words: SERVER CLASS
WORKS" and got back exactly that - plus confirmed on disk (not just in the
UI) that data/admin-state/ai-entitlement.json recorded the seat assignment
and ai-metering.jsonl recorded real prompt/completion token counts and
latency from the actual model call. Rejection-path logic (seat limit
reached, zero seats configured, revocation) covered by 5 new unit tests
rather than a second live round trip. Full suite: typecheck clean, lint
clean, translations 48/48, production build succeeds.

Bernd Rodler 5d7ae230ce feat(ai): real local Ollama chat + BYOK public provider
Decisions 2026-08-05 evening (reprioritizing docs/AI-ASSISTANT-CONCEPT.md's
original P1/P2 server-first sequencing to local-first, since a real Ollama
instance already runs on this Mac with a full model set):

- `local` ships free, no entitlement check — always available wherever
  supportsLocalLlm() is true.
- `public` (BYOK) is available too, explicitly unmonitored for now — no
  seats/metering/consent backend. This reverses the concept doc's decision
  #1 (server-side-only key custody): the client holds its own key, matching
  vncmail-native's existing pattern.
- `server` (VNC-hosted) stays unwired client-side; that infra is "this
  MacBook tonight, the dev k8s cluster tomorrow."

New:
- lib/ai/local-client.ts: listLocalModels/testLocalConnection/chatLocal/
  chatPublic, ported near-verbatim from vncmail-native's proven
  src/api/ai.ts. Direct browser-side fetch, not proxied through this app's
  own server — a server-side proxy would reach the *server's* loopback, not
  the user's own laptop, which defeats the point of "local" once this app
  is hosted remotely.
- lib/ai/key-store.ts: client-held BYOK storage (localStorage — this repo's
  existing convention for client state, no OS keychain reachable from a
  browser tab).
- lib/ai/local-settings.ts: isolated persistence for provider/model/base-URL
  choices. Deliberately NOT folded into stores/settings-store.ts, which has
  a hand-maintained export/import enumeration this prototype-scope state
  doesn't belong in yet.
- Retrieval reuses this app's own already-built app/api/offline/search
  (encrypted SQLite/FTS5 mail index) as context when available, and
  degrades to unaugmented chat — not an error — when it 404s/503s (no index
  in this session, e.g. plain browser rather than Electron).

Rewrote components/settings/ai-assistant-settings.tsx: provider picker,
local runtime config (base URL, model list/refresh, test connection with a
CORS-aware diagnostic per the concept doc's own note on the browser row),
public BYOK config (base URL, model, key, client-side consent toggle), and
a working Ask box.

Verified: typecheck clean, lint clean, translations pass, production build
succeeds. Live-tested against the real Ollama on this machine (confirmed
running: qwen2.5:32b, gemma4, deepseek-r1, llama3.2, hermes3, qwen3) via a
local server + demo-mode session — admin flag round-trips correctly, the
pane renders both provider options, and the CORS-diagnostic path fires
correctly on a real (if here environment-sandboxed, not Ollama-side)
connection failure. Full success end-to-end still wants a real, unsandboxed
browser tab against this Mac's loopback to close out.
2026-08-05 22:41:22 +02:00
Bernd Rodler 2a35019b21 feat(ai): P0 client scaffolding — capability flags, settings pane, policy fetch
Per docs/AI-ASSISTANT-CONCEPT.md §12, P0 is deliberately generation-free:
prove platform gating and the policy round trip before any model exists
behind it. No provider is called anywhere in this change.

- lib/platform-capabilities.ts: supportsLocalLlm/localLlmNeedsCorsSetup,
  mirroring the same-named module in vncmail-native so the capability
  contract (§3, §11) reads identically on both clients. Web+Electron only
  here — mobile is a separate codebase.
- lib/ai/types.ts: AiPolicy/AiEntitlement schema, locked in now per decision
  #4 (entitlement from day one — cheap now, a live-tenant migration later).
- app/api/ai/policy/route.ts: GET, unauthenticated (users read this, like
  /api/admin/policy). Composes the real FeatureGates.aiAssistantEnabled
  toggle with a hardcoded unlicensed entitlement — there's no seats/billing
  backend yet (P2), so nothing here can honestly claim otherwise.
- components/settings/ai-assistant-settings.tsx: fetches that policy, shows
  a real (not fake) locked/unlicensed state. No model config UI yet — there
  is nothing real to configure until P1/P2/P5 land.
- New admin FeatureGates.aiAssistantEnabled (default false, like
  pluginsEnabled): the tab is entirely hidden until an admin opts in, so no
  existing install suddenly sees a tab that does nothing.

Verified: typecheck clean, lint clean, translations test passes (48/48),
full production build succeeds with /api/ai/policy compiled in.
