Built-in memory (MEMORY.md/USER.md) is controlled by memory_enabled, not
memory.provider — but the desktop dropdown offered 'builtin' as a normal
provider-plugin value and gave it plugin-shaped affordances (config panel,
OAuth connect row), and the empty sentinel rendered as '(none)' even though
built-in memory was active.
- Label the empty memory.provider option 'Built-in only' (all locales).
- Drop the literal 'builtin' option from the desktop ENUM_OPTIONS and the
backend config-schema select; _normalize_memory_provider_name already maps
legacy builtin/built-in/none values to ''. A stored legacy literal stays
visible via enumOptionsFor's current-value passthrough.
- Gate MemoryConnect and ProviderConfigPanel behind a new
isExternalMemoryProvider() helper so built-in aliases never get
provider-plugin affordances.
The suite-wide conftest now pins HERMES_HONCHO_HOST=hermes (597615ade, after
this branch was written), which preempts profile-driven host resolution and
made the salvaged test write to the 'hermes' host key instead of
'hermes_worker'. Drop the override inside the test like the other custom
host-resolution tests do.
* fix(dashboard): resolve dashboard-owned assets from the process launch home
Profile-scoped chat / ?profile= requests install a context-local
HERMES_HOME override, which made custom dashboard themes AND user
dashboard-plugin extensions disappear once the embedded /chat started
under a different profile than the dashboard process.
Add get_process_hermes_home() (sharing _hermes_home_from_env() with
get_hermes_home() so the two can't drift, and splitting the profile
fallback warning into _warn_profile_fallback_once()) and use it for both
the theme YAML scan and the user dashboard-plugin scan — machine-level
assets that belong to the server's launch home and must not follow a
transient per-request override.
Genuinely profile-scoped callers (memories/backups/checkpoints/provider
config) and the paired _merged_plugins_hub classification are left
untouched so they keep following the override.
* test(dashboard): cover process-home asset discovery under profile override
- get_process_hermes_home(): env set returns that path, unset falls back
to the platform default, and an active context-local override is ignored.
- _discover_user_themes() and _discover_dashboard_plugins() keep returning
launch-home assets while a profile override scopes the request elsewhere.
Route the provider config endpoints on the surface query param exactly
as main does: surface=declared serves the curated schema (now sourced
from the plugins' config_schema.py instead of the deleted
hermes_cli/memory_providers.py), while the default surface keeps
serving the raw plugin schema that the web dashboard parses. Both
surfaces honor the profile query param.
The declared PUT returns {ok: true} to match main's contract; only the
raw-surface PUT reports the activated provider. The desktop client
requests surface=declared again, and the undeclared-provider tests use
builtin now that honcho has a declared schema.
Server-side coverage for the critical-CSS shim (PR #36024 salvage):
- user theme → style block emitted with ONLY real bundle variable names
(--background-base/--midground-base from layerVars(),
--theme-font-sans/--theme-base-size from typographyVars()/index.css),
and an html,body rule expressed via those vars so runtime theme
switches never leave a stale canvas/font
- built-in / unknown / non-string active theme → no block
- malformed theme YAML and load_config() exceptions → no crash, index
still serves
- </style> breakout attempt in a theme value stays escaped
- mount_spa integration: block present in <head> for user themes,
absent for built-ins
Conflict resolutions:
- web_server.py: keep the branch's unified provider-config handlers
(declared schema served by default, profile-scoped) over main's
surface=declared query param. Main's declared-surface helpers and the
hermes_cli.memory_providers import are dropped — the branch deleted
that module when provider schemas moved into their plugins, so main's
code path could no longer import.
- hermes.ts: keep profileScoped() calls without ?surface=declared to
match the unified backend.
- constants.ts: take main's new reasoning effort values (max, ultra),
keep the branch's memory provider ordering.
- config-settings.tsx: take main's FallbackModelsField import, drop the
now-unused SECTIONS import (branch replaced it with
sectionFieldEntries).
- provider-config-panel.test.tsx: file moved to settings/memory/ on the
branch; main's act() fixes targeted the old tests, and the rewritten
suite produces no act() warnings, so the old path stays deleted.
- test_web_server.py: keep both sides' new tests (main's MoA endpoint
tests plus the branch's Honcho provider tests).
Follow-up hardening on top of #64158 (@DavidMetcalfe):
Backend (the root-cause fix):
- hermes_cli/moa_config.py: add validate_moa_payload() — strict write-time
counterpart to the deliberately tolerant normalize_moa_config(). Flags
half-filled slots, empty reference lists, recursive moa slots, naming the
exact preset/slot.
- hermes_cli/web_server.py: PUT /api/model/moa validates before normalizing
and returns 422 with the specific problems instead of silently swapping the
user's preset for hardcoded defaults (#64156). Also declares
fanout / reference_max_tokens / reasoning_effort on the Pydantic payload so
client round-trips no longer erase hand-set values.
Desktop:
- Replace sanitize-then-send with hold-while-incomplete: the debounced
autosave is deferred (not repaired) while any slot is half-filled, and
flushes once the model pick completes the edit. Mid-edit UI state is never
repainted by a save response (generation guard covers held edits too).
- updateMoaSlot only clears the model when the provider actually changed.
- Explicit preset ops (set default / add / delete) cancel the pending
autosave and invalidate in-flight responses so the two writers can't race.
- Stable row keys (preset+index) so mid-edit rows don't remount; cleared
model shows the 'Model' placeholder instead of vanishing.
Both TS clients' MoaConfigResponse types now declare the round-tripped
fields (fanout, reference_max_tokens, reasoning_effort).
Tests: 12 new backend unit tests (validate_moa_payload contract incl.
validate/normalize agreement), 3 new web_server endpoint tests (422 on
half-filled ref/aggregator, fanout round-trip), 3 new desktop vitest cases
(autosave held while half-filled, flush on completion, same-provider
reselect no-op). E2E validated against a live TestClient with isolated
HERMES_HOME: bug sequence now 422s with config untouched.
Fixes#64156
The desktop provider panel previously rendered the curated declarations
from hermes_cli/memory_providers.py: five hindsight fields, and no panel
at all for undeclared providers like honcho (OAuth connect only). The
dashboard provider-switching rework re-pointed the shared config route
at raw plugin schemas, so the desktop began dumping every internal field
(35 for hindsight) and grew a bespoke honcho panel.
Serve both surfaces from the same route: ?surface=declared returns the
curated schema (empty for undeclared providers) with the original
config-file + env-store write semantics; the dashboard keeps the raw
plugin schema unchanged. The desktop client opts into declared.
The dashboard's dedicated memory-provider UI (4b184cbe5) excluded
memory.provider from /api/config/schema server-side. Desktop's settings
page builds its field list from that schema, so the Memory Provider
dropdown silently vanished from Desktop after v0.18.1.
- web_server.py: restore memory.provider as a select in _SCHEMA_OVERRIDES,
with options built from plugins.memory discovery (was a stale hardcoded
[builtin, honcho] list before the removal)
- plugins/memory: add list_memory_provider_names() — directory-scan-only
name listing, safe at module import time (no provider imports)
- web ConfigPage: hide memory.provider client-side instead — the Plugins
page owns the dedicated provider-switching UI there
- tests: schema contract (select present, category memory, builtin
sentinel) + invariant that every discoverable provider is selectable
Reject metadata that would make session queries fail, bound import work, and detach cyclic lineage links. Guard lineage traversal against pre-existing corrupt cycles.
The web UI CONFIG_SCHEMA showed ['ask', 'yolo', 'deny'] for the
approvals.mode select field. These don't match any real config values
and 'smart' mode was entirely unreachable from the dashboard.
Correct the options to ['manual', 'smart', 'off'] which match the
values defined and documented in hermes_cli/config.py.
Adds a regression test to TestBuildSchemaFromConfig to pin the correct
option names and guard against future drift.
Fixes#31925
No bundled provider declares actions, and the motivating request
(openviking, #56309) needs dynamic select options rather than actions.
Removing the unconsumed POST dispatch surface keeps this PR focused on
the config panel; the extension point can return as its own PR with its
first real consumer.
Dashboard Chat is an xterm mirror of a TUI inside the gateway, so
server-side clipboard.paste never sees the browser clipboard. Upload
pasted/dropped images to the profile's images/ dir (same place
clipboard.paste / image.attach use), then drive /image over the PTY.
Uses a dedicated /api/chat/image-upload endpoint (magic-byte check,
25MB cap, profile scope) instead of relative managed-files uploads that
400 on local dashboards without a locked root. Ctrl/Cmd+Shift+V also
tries clipboard.read() for images before falling back to text, since
preventDefault on that chord suppresses the DOM paste event.
Salvages #57912 (client composition + /image PTY drive) and folds in
#48563's upload endpoint + drop path.

Rebase reconciliation with #60884: _count_status_active_sessions (from
#58238) now passes compact_rows=True (this branch's #47437 projection),
so the fake asserts both.
Review finding: SessionDB(read_only=True) requires the DB file to exist
(its documented contract says callers guard on db_path.exists()); on a
fresh install every /api/status poll paid an OperationalError until the
first session was written. Short-circuit to 0 when state.db is absent.
Tests: fresh-install guard + existing read_only test adjusted.
The #39140 CTE used UNION ALL, which recurses forever if a corrupted
parent chain loops (a -> b -> a) — reproduced: query never returns. The
old Python walk was cycle-safe via a seen-set. UNION dedups the working
set and terminates. Regression test added and mutation-verified (UNION
ALL hangs the test, UNION passes).
Main's #60569 (dashboard memory provider switching) rewrote the same
GET/PUT /api/memory/providers/{name}/config routes this PR owns — the
dashboard and desktop share one backend. Resolve by dispatching: providers
that declare a config_schema.py get the declared path (host-block storage,
locked honcho writes, profile scoping, actions); everything else keeps
main's instance get_config_schema()/save_config path unchanged, so the
dashboard's PluginsPage behavior is preserved for instance providers.
Setup manifests, the /setup endpoint, provider switching, and name
validation from #60569 apply to both paths. Instance payloads gain the
docs_url/actions keys the desktop panel expects; declared payloads gain
the setup block the dashboard expects. Main's hindsight/honcho instance-
schema tests are updated for the dispatch, and its status test gets the
HOME pin it was missing (it read the developer's real ~/.honcho).
Strict charset allowlist (alnum + - _, max 64) on the {name} path param of
the memory-provider config/setup endpoints. Prevents traversal-shaped names
from reaching find_provider_dir(), and setup now 404s when neither a
loadable provider nor a plugin manifest exists, so the command-running path
is only reachable for discoverable plugins. Adds regression tests.
Headless/hosted deploys run the dashboard server without COLORTERM in
the process environment, so chalk inside the PTY-spawned TUI child
downgraded every skin hex color to the xterm 256 palette — the default
skin's bronze banner border (#CD7F32) snapped to palette 173 (#D7875F,
salmon red) and the gold caduceus rendered red/yellow on fresh cloud
instances. Local launches never reproduced it because the operator's
interactive terminal leaks COLORTERM=truecolor into the server env.
xterm.js always renders 24-bit RGB, so the dashboard PTY child should
always advertise truecolor: backfill COLORTERM=truecolor in
_resolve_chat_argv via setdefault (an explicit operator value wins).
Verified with a clean-env PTY probe of the real TUI binary:
no COLORTERM -> 0 truecolor SGRs / 165 palette-256 (salmon 38;5;173);
with the backfill -> 166 truecolor SGRs, exact bronze 38;2;205;127;50.
Providers with behavior beyond fields (validate a server, start a local
instance, link a CLI profile) previously had no mount besides forking the
panel. Let the schema declare actions and one generic endpoint run them:
ProviderAction on ProviderConfigSchema, POST
/api/memory/providers/{name}/actions/{action} dispatching to
ACTION_HANDLERS in the plugin's config_actions.py (path-loaded and
import-light, like the schema), profile-scoped and off the event loop.
Handlers get the submitted values dict, return a JSON-able result, and
raise ValueError for user-facing 400s. The panel renders declared actions
as generic buttons beside Save. No bundled provider declares actions yet.
The settings page follows the desktop's active-profile switcher, but the
provider config calls didn't: no profileScoped() on the client and no
profile param on the backend, so a multi-profile desktop edited the serving
process's config while every surrounding card showed the selected profile's.
Accept ?profile= on both endpoints and resolve inside _profile_scope (the
skills/toolsets contract), spread profileScoped() into the two client calls,
and key the schema cache on the resolved config_schema.py path instead of
the provider name — user-installed plugins are per-profile, so one profile's
lookup must never answer for another's.
ruff check --fix --select F541 . on current main. Pure prefix removals;
adjacent-string concatenations keep the f only on interpolating fragments.
No string content or live placeholder altered.
Post-merge follow-ups + several review rounds + a hub-search rework, folded together.
Merge-scuff restores (a stale-base refactor had reverted two live-on-main fixes):
- gateway: SessionStore compression-tip healing + its regression test.
- desktop: messaging session/transcript polling in desktop-controller
(MESSAGING_POLL / ACTIVE_MESSAGING_SESSION_POLL, refreshMessagingSessions,
refreshActiveMessagingTranscript, the richer sameCronSignature) so inbound
platform traffic updates live again instead of freezing until manual refresh.
Profile-switch isolation (epoch/close/guard on every profile-scoped async):
- Hub store clears + in-flight runHubAction bails (and swallows the post-switch
404 instead of a phantom toast); hub preview/scan/search/sources profile-scoped.
- MCP: probe/auth epoch guards, dirty-draft reset, sidebar mutations blocked
until config resettles AND every persist re-checks the epoch post-await;
profilePending clears on config settle incl. error; logs re-key on profile.
- Model settings reload on switch and epoch-guard setModelAssignment /
saveMoaModels / API-key activation.
- Config draft resets + cancels its autosave on switch; skill editor/archive and
star-map node dialogs close on switch; openSkillEditor / star-map openEdit
discard stale fetches; tool-usage analytics loads are profile-guarded/keyed.
Correctness + UX:
- Unique per-skill action names for hub install AND uninstall; hub/catalog rows
flip only on a clean exit_code; catalog install polls the background bootstrap
to completion, reconciles the mcp.json draft (no dropped server), and fails
loudly on non-zero exit; MCP catalog query keyed by profile.
- /test reports needs-auth for anonymous auth:oauth servers; /auth snapshots +
restores tokens on a failed re-auth and clears the full 300s callback window.
- config-settings shows a retry on load failure; CodeEditor/JsonDocumentEditor
go read-only while saving so edits typed mid-save aren't dropped.
- Deep-link highlighter deletes its param only after a successful scroll.
- Restored the PageSearchShell trailing slot → Artifacts refresh button/spinner.
- /settings?tab=mcp redirect keeps server=.
Progressive hub search: fan out one query per backend-searchable source
(index-covered API sources stay unsearchable → no ~70-call GitHub re-hammer),
merge/dedupe by trust as each lands, per-source spinner overlaid on the dimmed
chip — results stream in without blocking on the slowest, no layout shift.
test(web): /api/skills list carries usage + provenance (CI contract).
* feat(desktop): CLI/dashboard parity — skills hub browser, MCP test/toggle/catalog, maintenance ops, log filters
Brings desktop GUI to parity with hermes skills/mcp/doctor/backup/debug-share/
curator/memory CLI commands and the dashboard's System + Skills-hub pages:
- Skills page: new Browse Hub tab (search official/GitHub/community sources,
preview SKILL.md, security scan verdicts, install/update with live action log)
- MCP settings: connection test (tool listing), per-server enable/disable
toggle, and a Catalog tab installing Nous-approved MCP servers with env prompts
- Command Center: new Maintenance section (doctor, security audit, backup,
debug share links, curator status/pause/run, memory file status + reset)
- Command Center system logs: file (agent/errors/gateway/desktop), level, and
substring filters instead of a fixed agent.log tail
- hermes.ts API client + types for all the above; en/zh locale strings (ja and
zh-hant inherit via defineLocale)
* feat(desktop): backend model catalogs in toolset config — hermes tools parity
Completes the `hermes tools` parity gap: after picking an image/video
generation backend the CLI runs a model picker (e.g. FAL's multi-model
catalog with speed/strengths/price); the desktop toolset drawer now has the
same flow as a radio-card list.
- web_server: GET /api/tools/toolsets/{name}/models (catalog + current +
default for the active or named provider row) and PUT .../model
(validated write to image_gen.model / video_gen.model), reusing the CLI's
plugin catalog helpers so GUI and `hermes tools` stay in lockstep
- desktop: ModelCatalogPicker in ToolsetConfigPanel — per-model cards with
speed/strengths/price, in-use + default badges, disabled until the
backend is the active one; provider selection now mirrors is_active
locally so the catalog unlocks without a refetch
- tests: 3 backend endpoint tests (catalog shape invariants, persist +
validation), 2 component tests, 2 API-contract tests; en/zh strings
Multi-line comment blocks and JSDoc-style headers across the provider
config surface compress to one line each; the why lives in commit messages
and docstrings, not comment essays.
The panel's PUT hand-rolled its target: hardcoded profile-local path while
reads used resolve_config_path(), always the underscore host key while reads
honor legacy dot-form blocks, apiKey to the env store which the client ranks
below a JSON-stored key, and an unlocked read-modify-write of the file the
OAuth refresh loop guards with an advisory lock because refresh tokens are
single-use. Any of the first three silently shadowed or bypassed live
settings on save; the fourth could revoke the OAuth grant.
Route the write through resolve_config_path() and _host_block (updating the
resolved block in place), persist a saved apiKey into the host block where
the client reads it — never over an OAuth access token, which the refresh
loop owns — and take _config_refresh_lock around the read-modify-write.
Tolerate hosts:null instead of 500ing.
Add registry/schema tests for the Honcho provider and keep the Hindsight
ones (now asserting inline). Add web_server tests for the honcho_host_block
backend (host/root scoping, native bool/number/json coercion, partial
saves, secret redaction). Port the inline-panel + full-config-modal desktop
tests and assert honcho is offered ahead of hindsight.
Follow-up on the salvaged #47491 commits:
- Register _plugin_api_runtime_gate BEFORE the auth middlewares so it
executes AFTER them, and add an explicit auth check: unauthenticated
requests to /api/plugins/<name>/ fall through to auth's 401 instead of
this gate's 404. Prevents the gate from becoming a plugin-name oracle
(an unauthenticated caller could otherwise fingerprint installed/enabled
plugins by status code). Keeps test_non_kanban_plugin_route_requires_auth
green.
- Enable the 'example' user plugin in the _install_example_plugin test
fixture so the auth / static-asset-allowlist tests still reach the real
serving paths now that user plugins are gated on plugins.enabled.
- Mark the runtime-gate unit-test scopes as authenticated so they exercise
the enabled/disabled policy under the new auth-first ordering.
`serve` (added in #54568) reused cmd_dashboard wholesale, so it still
behaved like a dashboard: it ran a full vite build every launch, mounted
and served the SPA whenever a stray web_dist/ existed, printed
"Hermes Web UI →", and announced HERMES_DASHBOARD_READY. It's the headless
JSON-RPC/WS backend the desktop app and remote clients run — pure socket
clients that never load the browser SPA.
Mark serve with headless_backend=True (resolved once in cmd_dashboard) and:
- skip _build_web_ui entirely on the serve path
- export HERMES_SERVE_HEADLESS=1 so mount_spa() disables the SPA even when a
dist is present — only the JSON-RPC/WS/API surface is reachable
- announce the bind ("Hermes backend listening on host:port") instead of a
browser/auth-gated URL
- print a neutral HERMES_BACKEND_READY sentinel; dashboard keeps the legacy
one and the desktop port-discovery regex matches either
- preserve serve across the named-profile re-exec so it can't rebuild as
dashboard
`hermes dashboard` is unchanged (builds + serves the browser UI). Backward
compatible: old apps only ever spawn dashboard (legacy token + UI intact)
and never invoke serve; the ready-file side channel is name-agnostic. The
one behavior change is that a remote `hermes serve` no longer serves the
browser dashboard as a side effect — that's `hermes dashboard`'s job.
Tests: serve headless_backend contract, SPA-disabled-with-dist, the
HERMES_BACKEND_READY desktop parse (17/17 node), and the existing
serve/dashboard/web_server suites. AGENTS.md documents the behavior.
Add a generic suppress_notification flag to the drain-request marker. When a
drain that ends in process exit (e.g. a NAS auto-update image migration on the
always-on Hermes Cloud fleet) is flagged, the gateway skips ONLY the
home-channel 'gateway shutting down' broadcast — the operator-flavoured ping
that would otherwise fire on every routine auto-update, dozens of times a day.
The per-active-session interrupt ping is ALWAYS kept: on a drained shutdown
it's empty by construction, and in the force-interrupt (deadline-exceeded) case
it carries the user-valuable 'your task was cut off, message me to resume' hint.
The gateway stays agnostic about WHY a drain is quiet (generic boolean, not a
kind enum); the policy of which drain causes set the flag lives in the caller
(NAS). Default-false so legacy/operator drains behave exactly as before. The
reader reuses the NS-570 epoch-staleness check so an orphaned marker on the
durable volume can never silence a fresh gateway's legitimate broadcast.
- drain_control.py: write_drain_request gains suppress_notification; new
drain_notification_suppressed() reader (current-epoch + truthy flag).
- web_server.py: /api/gateway/drain reads + echoes the flag.
- run.py: _notify_active_sessions_of_shutdown skips the home-channel loop only.
Tests prove: flag round-trips; home-channel suppressed when set, kept when
unset; active-session ping always fires; stale/legacy/corrupt markers never
suppress.
* fix(windows): stop terminal-window popups from background spawns
Native-Windows desktop/gateway users saw cmd/conhost windows flash on
gateway restart, image paste, the dashboard Projects tree, voice notes,
and ~5 min after closing the app (detached cron). Two root causes:
- Console-subsystem exes (taskkill, schtasks, wmic, netstat, tasklist,
agent-browser, git, ffmpeg, powershell, git-bash) spawned via raw
subprocess allocate a fresh console when the launching process has
none (pythonw desktop backend / detached gateway) - even with output
captured.
- uv venv pythonw shims re-exec console python.exe, so Python children
get a console regardless of how they're launched.
Fixes:
- Single hidden-spawn primitive (_subprocess_compat.run/.popen) that ORs
CREATE_NO_WINDOW on Windows, no-op on POSIX. Route every Hermes-owned
console-exe spawn through it.
- FreeConsole() catch-all in hermes_bootstrap: any Python child that
exclusively owns an auto-allocated console detaches it at startup
(GetConsoleProcessList()==1 gate leaves shared interactive consoles
untouched).
- Replace PowerShell/wmic gateway PID scans with in-process psutil.
- Skip schtasks queries on non-interactive desktop restarts.
- Prefer native agent-browser .exe over .cmd shims.
- Guard test bans raw subprocess spawns of the Windows-only console
tools repo-wide so the popup class can't regress.
* fix(windows): scope FreeConsole to background entry points; fix merge fallout
Console detach review (per #53810 feedback): GetConsoleProcessList()==1 can't
tell a uv pythonw->python phantom console apart from a user opening the
interactive CLI/TUI in its own fresh console (double-click, shortcut, ConPTY) —
both report a single attached process with a tty. Running FreeConsole() in the
import-time bootstrap therefore risked detaching a legitimately-interactive
terminal.
- Extract FreeConsole into explicit hermes_bootstrap.detach_orphan_console();
remove it from apply_windows_utf8_bootstrap() (import side effect).
- Call it only from known background mains: gateway run, dashboard backend
(start_server, what the desktop spawns), cron standalone, tui_gateway entry,
slash worker. Interactive CLI/TUI never calls it.
- Behavior-contract tests: frees only when solo owner, leaves shared console,
no-op without console / on POSIX, and asserts it's not an import side effect.
Merge fallout from origin/main (#53791):
- local.py: 3-way merge left a dangling **_popen_kwargs (NameError crashing
every terminal init). _subprocess_compat.popen already hides the window, so
drop it.
- discord adapter: merge stacked an undefined windows_hide_flags() onto the
primitive call; drop the redundant arg.
- test_gateway: scan now goes psutil-first (zero spawn); rewrite the
case-variant test to drive that production path.
* test(claw): mock _subprocess_compat.run seam for Windows process scan
claw.py's Windows tasklist/powershell scan routes through the hidden-spawn
primitive; the tests still patched claw_mod.subprocess, so on win32 the mock
was never hit and real spawns returned nothing. Patch the actual seam.
The dashboard Config tab's Model field is a flat string with no provider
info. _denormalize_config_from_web only updated model.default and kept the
stale provider, so picking an OpenRouter model while the default provider was
ollama-local left provider=ollama-local and every call 404'd.
When the model string actually changes, infer the serving provider — curated
catalog first, then a vendor/model-slug heuristic for non-aggregator providers
— and route the switch through the existing _normalize_main_model_assignment /
_apply_main_model_assignment chokepoints so stale base_url/api_mode/api_key are
cleared on a provider change and preserved on a same-provider re-pick. Saving
an unchanged model never re-detects, so unrelated config saves keep an explicit
provider.
Closes#14058
