Two small a11y fixes for the floating legend.
1. Both buttons (open pill + close ×) had no focus-visible ring —
keyboard users couldn't tell where focus landed. Added the
accent-ring pattern used across the rest of the canvas.
2. Close button was a ~10x16px hit area — well below WCAG 2.5.5's
24x24 minimum. Bumped to w-6 h-6 with negative margin so the
visible × stays in the same spot but the hit area + focus ring
are larger. Hover bg added to make the hit area visible on hover.

Three fixes for the cookie banner:
1. role="dialog" aria-modal="true" → <section role="region">. The
banner has no focus trap, doesn't block the page, and the user
can keep using the canvas while it's up — none of which are modal
semantics. Claiming aria-modal="true" without a trap actively
harms screen-reader users: they're told the rest of the page is
inert, jump into the banner, and then can't escape. Region
semantics let AT navigate around it normally. (Forcing a modal
cookie banner would also be a dark pattern under GDPR.)
2. Privacy-policy link: hover:text-accent → hover:text-accent-strong.
The original was a no-op (same color). Also added focus-visible
ring + underline-offset so the link is readable AND keyboard-
distinguishable in both themes.
3. Both buttons: focus-visible:ring-2 + ring-offset-surface so
keyboard users see where focus lands. Mouse clicks unchanged
thanks to focus-visible.
Tests: swapped getByRole("dialog") → getByRole("region") in 8
existing tests, then tightened the role-assertion test into a
regression guard that explicitly asserts NO aria-modal and NO
dialog role exist. Full suite: 1220/1220.

Two small UIUX fixes for Cmd+K search.
1. Auto-highlight the first match while the user types. Before, Enter
on a non-empty query was a no-op — focusedIndex stayed at -1 until
the user pressed ↓. Standard search-palette behavior is to highlight
the top result so Enter just works. Empty query keeps -1 (opening
the dialog shows ALL workspaces; arbitrarily pinning one looks
wrong).
2. placeholder-zinc-400 → placeholder-ink-soft. The hardcoded zinc
broke the semantic-token pattern other inputs use; placeholder now
flips with theme correctly. (Also reordered focus:outline-none
ahead of the focus-visible variants — cosmetic, more idiomatic.)
Tests: replaced the "resets to -1" test with two new ones — auto-
highlight on a matching query (Enter selects without ArrowDown), and
no-results query stays a no-op. Full suite 1220/1220.

Two small fixes for the workspace right-click menu:
1. Off-screen clamp. Right-clicking near the right or bottom edge of
the canvas put part of the menu past the viewport — items hidden
under the scrollbar / off the screen. The menu now measures itself
on the same rAF that auto-focuses the first item, and shifts back
inside with an 8px margin (matching the floating-tooltip top-edge
clamp in Tooltip.tsx). Falls back to the raw cursor coords for the
first paint frame so there's no flash.
2. focus:ring-zinc-600 → focus-visible:ring-accent/50. The hardcoded
zinc tone broke the semantic-token pattern every other surface
uses; flipping to focus-visible also stops the ring from showing
when items are clicked with the mouse (only keyboard nav now
triggers the ring, matching Toolbar/SidePanel behavior).

Two diagnostic upgrades to the Playwright staging-setup harness, both
zero-behavior-change:
1. provision-failed throw now includes the full admin-orgs row (boot
stage, last error, terraform/SSM state, etc) instead of just the
slug. Every "provision failed: <slug>" in CI history was followed
by a manual repro to find out WHY — that round-trip is gone.
2. workspace-failed throw dumps the full /workspaces/{id} body when
last_sample_error is empty. Boot crashes, image-pull errors,
missing PYTHONPATH, and OpenAI-quota-at-startup all surface as a
bare "Workspace failed:" today (see #2632). Now they carry the
boot_stage / image / last_error fields the API row exposes.
No fix for the underlying flakes — those are tracked in #2632 (CP race)
and #2578 (OpenAI quota). This just stops them looking identical in the
CI log.

Three small a11y fixes for the global toast surface:
1. Esc dismisses the newest toast. Errors never auto-expire, so without
a keyboard shortcut a keyboard-only user has to tab through the entire
app to reach the × button on a stuck error.
2. Dismiss button gets focus-visible ring + theme-aware tint. The previous
`opacity-70 hover:opacity-100` gave no visible focus indicator (WCAG
2.4.7). Info toasts use the semantic surface that flips with theme,
so the dismiss tint splits per type — accent ring on info, white ring
on the always-dark success/error toasts.
3. Touch target bumps from p-1 (~24x24) to w-7 h-7 (28x28) toward WCAG
2.5.5 AAA's 44x44 ideal.
Tests: 5 new vitest cases covering Esc on info/error, no-op on empty
queue, accessible label, and per-toast click dismissal.

WCAG 1.4.13 (Content on Hover or Focus) requires that tooltip content
be DISMISSIBLE without moving pointer hover or keyboard focus. Tooltip
had no escape hatch — once a keyboard user tabbed onto a control with
a tooltip, the tooltip stayed visible until they tabbed away (which
moves focus and may not be possible if the tooltip is itself blocking
content the user needs to see, e.g. for screen-magnifier users).
Add a window-level Escape listener that's active only while a tooltip
is shown. Pressing Esc clears the tooltip without moving focus or
breaking the hover state, satisfying the dismissible criterion.
Used `capture: true` so we beat any modal/dialog Esc handler that
might also be listening — the tooltip belongs to the focused control,
not the modal it sits inside.

The External Connect modal had tabs for Python SDK / curl / Claude Code
channel / Universal MCP. Operators using hermes / codex / openclaw as
their external runtime had no copy-paste; they pieced together
WORKSPACE_ID + PLATFORM_URL + auth_token into config files by reading
docs.
Adds three runtime-specific snippets stamped server-side:
- **Hermes** — installs molecule-ai-workspace-runtime + the
hermes-channel-molecule plugin, exports the 4 env vars, and writes
the gateway.plugin_platforms.molecule block into ~/.hermes/config.yaml.
Same long-poll-based push semantics the Claude Code channel tab
delivers (push parity with the in-tree template-hermes adapter).
- **Codex** — wires the molecule_runtime A2A MCP server into
~/.codex/config.toml ([mcp_servers.molecule] block with env_vars
passthrough + literal env values). Outbound tools only — codex's
MCP client doesn't route arbitrary notifications/* (verified by
reading codex-rs/codex-mcp/src/connection_manager.rs); push parity
on external codex would need a separate bridge daemon, tracked
as future work. Snippet calls this out so operators know to pair
with Python SDK if they need inbound delivery.
- **OpenClaw** — installs openclaw + onboards, wires the molecule
MCP server via openclaw mcp set, starts the gateway on loopback.
Same outbound-tools-only caveat as codex; the in-tree template-
openclaw adapter implements the full sessions.steer push path,
but an external setup would need the same bridge daemon to translate
platform inbox events into sessions.steer calls. Future work.
Default open tab changed from "Claude Code" to "Universal MCP".
Universal MCP is runtime-agnostic and works as a starting point for
any operator regardless of their downstream agent runtime; runtime-
specific tabs are still one click away. Pre-2026-05-03 the modal
defaulted to Claude Code, so operators using non-Claude runtimes
opened to a tab they had to skip past.
Tab order also reorganized:
Universal MCP → Python SDK → Claude Code → Hermes → Codex → OpenClaw → curl → Fields
Each runtime-specific tab is gated on the platform supplying the
snippet (older platform builds without the field don't show empty
tabs).

User feedback: chat-bubble agent text still washed out after #2618 +
#2623. Looked at the actual rendered colors and the issue was Tailwind
Typography's `prose-invert` defaults — body text ships at zinc-300,
which lands at ~5.3:1 against bg-zinc-700. Passes AA but visibly
duller than the user bubble's crisp white-on-blue (~10:1).
Override the prose CSS variables on the agent bubble in dark mode:
- body → zinc-100 (was zinc-300)
- headings / bold → white
- inline code → zinc-100
That brings agent body text to ~13:1 against bg-zinc-700, matching the
user bubble's brightness so both sides of the conversation read at
the same crispness.

Same bug class as #2622 (ConfirmDialog), but on a more critical surface
— this is the top-of-page banner asking the user to approve / deny a
real workspace permission request.
1. **Deny was a no-op hover.** `bg-surface-card hover:bg-surface-card`
gave zero visual feedback before the user clicked a destructive
action. Now lifts to surface-elevated + brightens the text so the
button visibly responds.
2. **Approve hover went LIGHTER.** `bg-emerald-600 hover:bg-emerald-500`
dropped white-text contrast on hover. Reversed to emerald-700.
3. **No focus rings on either button.** Keyboard users had no way to
tell which decision was focused. Added focus-visible rings
(offset against the dark amber banner bg) — emerald for Approve,
amber for Deny so the choice is unambiguous.

Discovered during code review of the #2623 hotfix audit. Same
regression class as #2618: prose-invert applied where the bubble bg
themes between light/dark, leaving markdown unreadable in one theme.
`MarkdownBody` was unconditionally `prose-invert` — fine for the
outgoing-message bubble (bg-cyan-900, dark in both themes) and the
failure bubble (bg-red-950, dark in both themes), but WRONG for the
incoming-message bubble (bg-surface-card, which themes LIGHT in light
mode). Result: light prose body text on light cream bg = invisible
markdown for incoming peer-to-peer messages in light mode.
Added an `invert: "always" | "dark-only"` prop to MarkdownBody. The
NormalMessage call sites switch on `msg.flow` so each bubble gets the
direction matching its bg's theming behavior. Failure bubble keeps
the default ("always") since red-950 stays dark.

Regression from PR #2618 (chat dark-contrast).
PR #2618 switched the agent bubble bg to `dark:bg-zinc-700` so it
visibly elevates against the dark panel — but the inner ReactMarkdown
prose div only got `prose-invert` for USER messages. Result: in dark
mode the agent's markdown text rendered with the Tailwind Typography
plugin's default dark body color on top of the new dark bg = invisible
text. User reported empty-looking gray rectangles where agent replies
should be.
Fix: apply `dark:prose-invert` to agent bubbles so prose body text
flips light alongside the bg. Light mode unchanged (default prose
colors against the warm `bg-surface-card`).

Three issues on a high-stakes surface (revoke token, delete workspace,
cascade delete):
1. **Cancel hover was a no-op.** `bg-surface-card hover:bg-surface-card`
gave zero visual feedback on hover. Now hovers to surface-elevated
with a softened border so the button visibly lifts.
2. **Confirm hovers went LIGHTER, dropping white-text contrast.**
`bg-red-600 hover:bg-red-500` made the destructive button less
readable on hover. Same for warning (amber) and primary (accent).
Reversed to hover-darker so contrast holds in both themes.
3. **No focus-visible rings on either button.** Keyboard users had no
indication of focus position (WCAG 2.4.7 fail). Added
`focus-visible:ring-2 focus-visible:ring-accent/40` on Cancel and
`focus-visible:ring-2 focus-visible:ring-offset-2 ...accent/60` on
Confirm so the focused destructive action is unambiguous.

User screenshot showed pale lavender user bubbles with hard-to-read white
text and a nearly-invisible agent bubble blending into the dark panel.
Root causes:
1. Tailwind v4 defaults `dark:` to `prefers-color-scheme: dark`. Our
ThemeProvider writes `data-theme="dark"` on <html> so user toggle wins
over OS — but `dark:` classes elsewhere in the codebase weren't
tracking it. Added `@custom-variant dark` to re-bind the variant.
2. `bg-accent` themes lighter in dark mode (--color-accent: #6883e8),
dropping white-text contrast to ~3:1 (fails WCAG AA). Switched user
bubble to solid blue-600/500 so it stays ~5:1 in both modes.
3. `bg-surface-card` (#1a1d23) was only ~7% lighter than the panel bg
(#0e1014), making agent bubbles disappear. Bumped to zinc-700 in
dark; light mode keeps the warm surface-card tint.
4. System (error) bubble's /10 overlay was nearly invisible; raised to
/25 in dark with stronger border + ink for readability.
Sub-tab + textarea polish included: low-contrast `text-ink-soft` →
`text-ink-mid`, focus-visible rings on tabs, dark variants on textarea.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Top-of-canvas Toolbar had multiple low-contrast surfaces in light theme:
Action buttons (Stop All, Restart Pending):
- bg-red-950/50 + bg-amber-950/40 → bg-bad/10 + bg-warm/10 with bg-bad/40
+ bg-warm/40 borders. Dark-tinted backgrounds with /40-/50 alpha render
as nearly invisible smudges on warm-paper; semantic tokens at /10 give
a clear pale-bad / pale-warm tint that scales correctly in dark mode.
- Both gain focus-visible:ring-2 focus-visible:ring-{bad,warm}/40.
Toggle button (A2A edges):
- Active state: bg-blue-950/50 → bg-accent/15 (themes correctly).
- Inactive state: bg-surface-card/50 + text-ink-soft → solid bg-surface-card
+ text-ink-mid; hover bumps to text-ink. Drops the redundant
"hover:bg-surface-card/50" identity hover.
Icon buttons (Audit, Search, Help):
- Same pattern as toggle inactive: solid bg-surface-card + text-ink-mid +
text-ink hover, with focus-visible:ring-2 focus-visible:ring-accent/40.
Workspace count + bullet separator:
- text-ink-soft (3.5:1 on warm-paper) → text-ink-mid (7:1).
WS connection status:
- "Live": text-ink-soft → text-ink-mid (paired with the green dot).
- "Reconnecting": text-ink-soft → text-warm (semantic match for amber dot).
- "Offline": text-ink-soft → text-bad (semantic match for red dot).
Status text now reinforces the dot colour instead of disappearing on
light surfaces.
Help popover:
- Close button: text-ink-soft → text-ink-mid + focus-visible:underline.
- HelpRow body text: text-ink-soft → text-ink-mid (was 3.5:1 on the
bg-surface-sunken/45 popover row — failed AA for body text).
Chat bubble fixes (canvas/src/components/tabs/ChatTab.tsx):
- User bubble: bg-accent-strong/30 + text-blue-100 → bg-accent + text-white
(translucent dark-blue overlay on warm-paper surface read as pale lavender
with near-invisible light-blue text — a real WCAG AA failure on the
highest-traffic surface in canvas).
- System/error bubble: bg-red-900/30 + text-red-200 → bg-bad/10 + text-bad,
using semantic tokens so dark-mode adapts automatically.
- Agent bubble: drop /80 + /30 opacity modifiers; solid bg-surface-card +
text-ink + border-line gives consistent contrast in both themes.
- prose-invert was unconditional, so markdown text on agent/system bubbles
rendered as light text on a light surface in light mode. Make it apply
only on the user bubble (the only dark surface in this component).
- Timestamp: text-ink-soft is too pale on warm-paper; use text-ink-mid for
agent/system, white/70 for user (visible on the now-solid blue bg).
Sub-tab bar fixes (canvas/src/components/SidePanel.tsx):
- Right-edge fade was hardcoded `from-zinc-950` — that paints a dark vertical
strip on the right edge of the tab bar in light mode. Switch to
`from-surface` so the gradient blends into whichever theme is active.
- Inactive tab text: text-ink-soft (~3.5:1 on warm-paper) → text-ink-mid
(~7:1). Active tab background: drop the /40 opacity so the selection is
unambiguous on either surface.
No semantic-token additions; all changes use existing warm-paper tokens
that already work in both themes.
Three loading-state divs were missing the role/aria pattern that
TemplatePalette.tsx and EmptyState.tsx already follow. Screen readers
get no signal that the page is waiting:
- canvas/src/app/page.tsx — full-screen "Loading canvas..." while
the websocket hydrates. First paint of the entire app.
- canvas/src/components/settings/TokensTab.tsx — "Loading tokens..."
- canvas/src/components/settings/OrgTokensTab.tsx — "Loading keys..."
Add role="status" + aria-live="polite" to the wrapping div so
assistive tech announces the wait and the eventual transition.
Visual rendering unchanged.
The tier system in CreateWorkspaceDialog and design-tokens has been
T1 Sandboxed / T2 Standard / T3 Privileged / T4 Full Access, but two
chrome surfaces still showed the older 3-tier mapping with T3 as
"Full Access":
- Legend (bottom-left chrome on every canvas page) listed only T1/T2/T3
and called T3 "Full Access". On a SaaS tenant the actual workspace
badges render T4 (in amber/warm) — there was no T4 entry in the
legend at all, so the user sees an undocumented orange badge.
- ConfigTab tier dropdown (per-workspace settings → Sandboxing) had no
T4 option at all and called T3 "Full Access". So an existing T4
workspace would show "T3 — Full Access" as the selected option,
silently downgrading the displayed tier on the settings panel.
- tenant.ts isSaaSTenant() doc comment claimed SaaS workspaces are
"inherently T3 Full Access" — wrong on both the number and the lock
rationale (SaaS hides T1/T2/T3, not just T1/T2).
Fix:
- Legend now imports TIER_CONFIG and renders all four tiers
(Sandboxed/Standard/Privileged/Full Access) using the same color
swatches as the badges on workspace cards. Eliminates the previous
drift where Legend's hardcoded sky/violet/warm chips didn't match
the gray/sky/violet/amber actually rendered on nodes.
- ConfigTab adds the missing T4 — Full Access option and renames T3
to Privileged.
- tenant.ts comment updated to match the picker's actual hide list.

PR #2555 (Tailwind v4 + warm-paper) migrated all canvas chrome (toolbar,
side panel, modal layer) to semantic tokens, but missed the React Flow
viewport's `colorMode="dark"` literal — and two paired hardcoded dark
literals on the Background dot color and MiniMap mask. Net result on
prod: the user picked light mode, the toolbar flipped warm-paper, but
the canvas backplate, edges, dots, controls, and minimap stayed black —
visibly half-themed.
Three coordinated fixes inside the canvas viewport:
- ReactFlow `colorMode={resolvedTheme}` so the library's own dark/light
styles flip with the user's choice.
- Background dot color picks the line-soft tone in light mode (zinc-800
was invisible-on-cream).
- MiniMap maskColor warm-tints the off-viewport dim so the unselected
region doesn't render as a hard black bar over warm-paper.
Verification:
- `npx tsc --noEmit` clean
- `npx vitest run` 188/188 pass
- (will browser-verify post-redeploy on hongming.moleculesai.app)

Independent code review of #2555 caught two contrast regressions left
by the bulk perl pass:
1. text-white → text-ink mass-substitution silently broke destructive
and primary buttons. text-ink resolves to #15181c (warm-paper
near-black) in light mode — dark text on bg-red-600 / bg-amber-600
/ bg-emerald-600 / bg-blue-600 / bg-accent / bg-accent-strong /
bg-good / bg-bad fails WCAG contrast and looks broken. Per-line
pass flips text-ink → text-white only when a saturated bg utility
is present; tinted-state pills (bg-red-950/50 etc.) keep their
intentionally-retained text-* literals.
2. Original mapping table was missing bg-zinc-600 (most-used
hover-state literal for cancel buttons — caused them to JUMP from
warm cream resting state to dark zinc on hover in light mode) and
text-zinc-700/800/900 (separator dots and decorative dim text
invisible on warm-paper light bg). Extended mapping fills these
gaps with bg-surface-card / text-ink-soft.
Also: drop stale tailwind.config.ts reference from components.json
(file deleted by the v3→v4 migration); switch baseColor zinc →
neutral and enable cssVariables since v4 uses CSS-driven tokens.
Future shadcn-cli invocations would have failed or written malformed
components without this.
27 sites in 27 files affected by #1, ~20 sites in 20 files by #2.
1214/1214 unit tests still pass; build still clean.

CI's `npm ci` failed because the previous lock was generated on macOS
arm64, which omits the Linux-specific optional deps that
@tailwindcss/postcss → lightningcss-linux-x64-gnu transitively need
(@emnapi/runtime, @emnapi/core).
Re-ran `npm install --include=optional` so the lock includes every
platform variant of lightningcss + the @emnapi packages they pull in.
Runner (Linux x64) now has what it needs; local macOS install still
fine (npm picks the matching binary at install time).

PR #2545 self-review findings.
(1) originalModel was set from wsMetadataModel alone. On a hermes/pre-#240
workspace where MODEL_PROVIDER was never written but YAML has
runtime_config.model: "something", originalModel="" while the form
rendered "something" — handleSave's diff fired /model PUT on every
unrelated save (tier change → workspace auto-restart). Snapshot from
the actual rendered model in BOTH loadConfig branches so the diff
stays scoped to user-initiated changes.
(2) The store-flush test asserted the call happened but didn't pin
success-gating. A future refactor wrapping the PATCH in try/catch and
unconditionally calling updateNodeData would have shipped green and
left the badge lying about server-rejected writes. New test pins the
PATCH-rejects-no-flush invariant.
(3) Hermes-edge regression test for (1).
All 1214 canvas tests pass.

Three drift bugs in ConfigTab + ProviderModelSelector. Same root pattern:
the form's display, the diff baseline, and the canvas store all read or
write from different copies of the same data, so what the user sees and
what the runtime actually uses can diverge silently.
(1) currentModelId read runtime_config.model first; loadConfig overrode
only top-level config.model. With template YAML `runtime_config.model:
sonnet` and live MODEL_PROVIDER=`MiniMax-M2`, the form rendered
"Claude Code subscription / Claude Sonnet (OAuth)" while the container
env (and chat) used MiniMax-M2. Fix: loadConfig propagates
wsMetadataModel into BOTH places.
(2) handleSave's nextModel-vs-oldModel diff compared the form value to
the YAML default. After (1) mirrors wsMetadataModel into the form's
runtime_config.model for display, that diff was always non-zero on
no-op saves and would fire /model PUT — which auto-restarts. New
originalModel state tracks the loaded MODEL_PROVIDER and is the diff
baseline.
(3) handleSave PATCHed the workspace row but never pushed the same
fields into useCanvasStore.updateNodeData. User picked T3, hit Save &
Restart, DB updated to tier=3, header pill kept showing T2 until full
hydrate. Fix: mirror dbPatch into the store.
Bonus: ProviderModelSelector.handleProviderChange used to auto-default
the model to next.models[0] (alphabetically first) when switching
providers. User picked the MiniMax provider intending MiniMax-M2.7;
the form silently set MiniMax-M2 (first in the bucket) and the
workspace deployed with the wrong model. Now empty-default for
multi-model providers, force explicit pick — Save/Deploy already gate
on model.trim() === "".
Three new tests in ConfigTab.provider.test.tsx pin (1)/(2)/(3); two
existing ProviderModelSelector tests updated to reflect the no-silent-
default behaviour, with a new single-model-auto-pick test for the
0-vs-many boundary. 1212/1212 canvas tests pass.

The shared <ProviderModelSelector> component was authored on disk but
never landed — three deploy/configure surfaces still rendered the
legacy free-text "MODEL slug" input + provider-radio list. Tasks #239
and #243 closed at "component exists" rather than "user-visible
behavior changed", and the integration sat in a working-tree stash
that was never committed.
This PR is the missing integration:
- canvas/src/components/ProviderModelSelector.tsx (new, 509 lines):
single-source-of-truth Provider→Model cascade. Builds a catalog
from `template.models[].required_env` (groups by sorted+joined env
names so two MiniMax models with the same auth land in one
provider), exposes vendor detection helper + back-derivation. No
per-template hardcoding — fully driven by the upstream payload.
- canvas/src/components/MissingKeysModal.tsx: replaces the inline
`<input type="text">` + `<fieldset>` of provider radios with one
`<ProviderModelSelector>`. Same external contract
(`onKeysAdded(model)`), so callers in useTemplateDeploy don't move.
- canvas/src/components/tabs/ConfigTab.tsx: replaces ad-hoc Model
text input + Provider radio with the same selector, fixing the
display-vs-storage drift class that #190 first patched.
Tests
=====
- ProviderModelSelector.test.tsx (new, 269 lines): cascade behavior,
vendor auto-snap, back-derivation from saved config.
- MissingKeysModal.cascade.test.tsx: rewritten to assert dropdown
shape (was asserting the legacy text-input shape).
- ConfigTab.hermes.test.tsx + ConfigTab.provider.test.tsx: updated
for the new selector shape.
- 1208/1208 canvas tests pass locally.
User-visible fix: clicking any deploy/configure surface from the
sidebar now shows the cascade UX (Provider dropdown first, Model
dropdown filtered) instead of the legacy free-text MODEL slug.
Closes the integration gap behind #239 + #243. Builds on merged
runtime PRs #2538 (universal MODEL_PROVIDER) + #32 + #38 (per-vendor
audit).

The TemplatePalette deploy modal (MissingKeysModal → ProviderPickerModal)
let the model field and provider radio drift apart. When a hermes
template defaulted the model to "MiniMax-M2.7-highspeed" but the radio
defaulted to providers[0] (Anthropic), the env-var input below asked
for ANTHROPIC_API_KEY. A user pasting their MINIMAX_API_KEY there (or
just dismissing the dialog) ended up with a workspace whose
runtime_config.model=MiniMax + ANTHROPIC_API_KEY env — the hermes
adapter then crashed during boot before /registry/register, surfacing
as WORKSPACE_PROVISION_FAILED 12 minutes later.
Caught 2026-05-02 on hongming/Hermes Agent (workspace 95ed3ff2-…
ended with: "container started but never called /registry/register").
Sibling of the ConfigTab cascade fix in PR #2516 (task #236) — same
pattern, different surface. Plumbs the template's full ModelSpec[]
(with required_env per model) into the picker. When the typed model
matches a registry entry, snap the radio so the env-var fields
underneath match what the model actually needs.
Free-text models (typed slug not in the registry) and models with no
required_env (local/self-hosted endpoints) leave the radio alone — the
user can still pick a provider manually. Backwards-compat: callers
that don't pass `models` get the pre-cascade behavior, pinned by a
regression test.

Follow-up to PR #2509/#2510. The defensive v1-detection branches in
extract_attached_files (Python) and extractFilesFromTask (TypeScript)
were merged with comments claiming they fix a "v0→v1 silent-drop"
bug that surfaced as the 2026-05-01 hongming "no text content"
incident. Live test disproved that hypothesis: a2a-sdk's JSON-RPC
layer validates inbound requests against the v0 Pydantic union, so
v1 shapes are rejected at the request boundary — the v1 detection
branch is unreachable on the JSON-RPC ingress path. The actual root
cause of the hongming incident was the missing /workspace chown
fixed by CP PR #381 + test #382.
Update the comments to honestly describe these branches as
defensive future-proofing (kept against an eventual SDK schema
migration or in-process callers that construct Parts directly from
protobuf), not as fixes for an observed bug. Also trims
ChatTab.tsx's outbound-shape comment block from ~21 lines to a
3-line pointer to the SDK union.
Comment-only change. No behavior change. 86 workspace tests + 91
canvas tests still pass.
The previous PR (#2509) flipped canvas outbound file parts to the v1
flat shape `{url, filename, mediaType}` based on a hypothesis that
a2a-sdk's JSON-RPC parser silently dropped v0 `{kind:"file", file:{...}}`
shapes. Live test shows the opposite: a2a-sdk's JSON-RPC layer
validates against the v0 Pydantic discriminated union (TextPart |
FilePart | DataPart), so v1 flat shape is rejected with:
Invalid Request:
params.message.parts.0.TextPart.text — Field required
params.message.parts.0.FilePart.file — Field required
params.message.parts.0.DataPart.data — Field required
The actual root cause of the user-visible "Error: message contained
no text content" was the missing `/workspace` chown (CP PR #381 +
test pin #382), not a wire-shape mismatch. Verified end-to-end by
sending a v0 image-only message after PR #381 + workspace re-provision
— agent receives the file, reads its bytes, and replies normally.
Reverting only the canvas outbound shape. Defensive v1-tolerance
stays in:
- workspace/executor_helpers.py — extract_attached_files still
accepts v1 protobuf parts in case a future client emits them or
a future SDK release flips internal representation. Harmless on
the v0 hot path.
- canvas/message-parser.ts — extractFilesFromTask still tolerates
v1 shape on incoming agent responses. Some agents may emit v1
when their internal serializer round-trips through protobuf.
Tests stay green (91 canvas, 86 workspace).
Image-only chats surface "Error: message contained no text content"
because canvas posts v0 `{kind:"file", file:{uri,name,mimeType}}` shapes
that the workspace runtime's a2a-sdk v1 protobuf parser silently drops:
v1 `Part` has fields `[text, raw, url, data, metadata, filename,
media_type]` and `ignore_unknown_fields=True` discards `kind`+`file`,
producing a fully-empty Part. With no text and no extracted file
attachments, the executor's "no text content" guard fires.
Three coordinated changes close the gap:
1. canvas/ChatTab.tsx — outbound file parts now carry the v1 flat
shape `{url, filename, mediaType}` so the v1 protobuf parser
populates Part fields instead of dropping them.
2. workspace/executor_helpers.py — extract_attached_files learns the
v1 detection branch (non-empty `part.url` + `filename` +
`media_type`) alongside the existing v0 RootModel and flat-file
shapes. Defends every runtime that mounts the OSS wheel against
the same drop, including any pre-fix client still on the wire.
3. canvas/message-parser.ts — extractFilesFromTask tolerates the v1
shape on incoming agent responses too, so file chips render in
chat history regardless of which Part shape the runtime emits.
Test pins:
- workspace/tests/test_executor_helpers.py:
+ v1 protobuf shape extraction
+ empty-Part defense (v0→v1 silent-drop fall-through returns [])
- canvas message-parser test:
+ v1 protobuf flat parts
+ filename fallback to URL basename for v1
Previously the picker modal opened only when preflight failed OR the
template offered ≥2 provider options. Single-provider templates with
saved keys (claude-code, langgraph) deployed silently using the
template's compiled-in default model — denying the user a final
chance to override before an EC2 boots and burns billing on the
wrong tier.
The picker UI already supports the "all-keys-saved single-provider"
case as a confirm-only prompt (provider radio is hidden, model input
is pre-filled with template.model), so flipping shouldShowPicker to
unconditional is a one-line change with the picker UX absorbing it.
Test plan
- Existing "single-provider skips picker when preflight.ok" regression
guard inverted to assert picker always opens.
- Three happy-path tests refactored to drive through the picker via
a new deployThroughPicker helper instead of expecting an immediate
POST.
- POST-failure tests likewise refactored — the failure now surfaces
through the picker click-through path, not the direct deploy()
call.
- 15/15 tests pass; deploy-preflight.test.ts unchanged + 20/20.

Self-review of #2460 found two issues:
1. Critical: Override button in ProviderPickerModal called
/settings/secrets when no workspaceId, overwriting the GLOBAL
secret used by every workspace. The only consumers of this
modal today (TemplatePalette, EmptyState via useTemplateDeploy)
never pass workspaceId, so Override was always destructive.
Removed entirely — the picker still solves the user-reported
bug (always-ask + reuse saved keys); per-workspace key override
can be a separate PR that plumbs secrets through POST /workspaces.
2. Optional: /settings/secrets was being fetched twice — once
inside checkDeploySecrets (silently) and again in the hook to
populate configuredKeys. Surfaced configuredKeys on
PreflightResult so the hook re-uses the existing fetch.

Clicking a hermes template tile silently deployed when global env
covered the API key, producing "No LLM provider configured" 500
because the workspace booted with no explicit model slug — the
adapter fell back to its compiled-in default which 401s on the
user's actual provider key.
Fix: in useTemplateDeploy, open the picker whenever the template
declares ≥2 provider options, even when preflight.ok=true. The
modal renders pre-saved keys as Saved (with an Override link) and
adds a model input pre-filled from the template's default. Single-
provider templates (claude-code, langgraph) still skip the picker
since there's nothing to choose.
POST /workspaces now includes the picker's model slug so hermes-
style routing reads the prefix at install time.

Mirrors the data-driven pattern PR #2454 set in ConfigTab: read
runtime_config.providers from /templates and filter the modal's
provider <select> to that subset. Same source of truth, three fewer
hardcoded copies of the provider list.
Behavior:
- Template declares providers → dropdown shows only those.
- Template ships no providers field → fall back to full HERMES_PROVIDERS
catalog (back-compat for older templates / self-hosted setups).
- Declared list has no overlap with our static metadata → fall back to
full catalog so the form can't lock the operator out.
- hermesProvider snaps back to the first available pick when its
current value falls out of the filtered list.
Tests: 3 new pinning the filter, no-providers-field fallback, and
the unknown-providers fallback. All 27 CreateWorkspaceDialog tests
pass.

Option B PR-5. Canvas Config tab now exposes a Provider override input
that's adapter-driven from each runtime's template — no hardcoded
provider list in the canvas. PUT /workspaces/:id/provider on Save
when dirty; auto-restart suppression to avoid double-restart with
the model handler's own restart.
The dropdown's suggestion list comes from /templates →
runtime_config.providers (the field added in
molecule-ai-workspace-template-hermes PR #31). For templates that
haven't migrated to the explicit providers list yet, suggestions
derive from model[].id slug prefixes — still adapter-driven, just
inferred. This keeps existing templates working while platform team
migrates them one at a time.
workspace-server changes:
- Add Providers []string field to templateSummary JSON
- Parse runtime_config.providers in /templates handler
- 2 new tests pin the surfacing + omitempty behavior
canvas changes:
- Remove hardcoded PROVIDER_SUGGESTIONS constant
- Add provider/originalProvider state + PUT-on-save logic
- Add deriveProvidersFromModels() fallback helper
- Wire RuntimeOption.providers from /templates response
- 8 new tests pin the behavior end-to-end

The Model dropdown's onChange writes to config.runtime_config.model
whenever a runtime is set (hermes, claude-code, etc.), and only
falls back to top-level config.model when no runtime is selected.
But handleSave used to diff the new value against top-level
nextSource.model only — so for any runtime-bearing workspace, the
PUT /workspaces/:id/model never fired and MODEL_PROVIDER never
landed in workspace_secrets.
Symptom (2026-04-30, hongmingwang Hermes Agent
32993ee7-840e-4c02-8ca8-cb9d75d112a5):
- User picks minimax/MiniMax-M2.7-highspeed from the dropdown
- Hits Save & Restart
- Save reports success; restart fires
- The new EC2 boots with HERMES_DEFAULT_MODEL empty
- install.sh defaults to nousresearch/hermes-4-70b
- hermes-agent errors "No LLM provider configured" on every chat
turn because no NOUS_API_KEY / OPENROUTER_API_KEY is set
- Reload Config tab → model field reverts to whatever
GET /workspaces/:id/model returns (i.e. empty / template default)
handleSave now reads the effective model from runtime_config.model
first and falls back to top-level model for legacy no-runtime
workspaces. Same change for the old-value diff so a no-op Save
still skips the PUT.
Tests pin both branches: PUTs /model when the dropdown changed
runtime_config.model on a hermes workspace; does NOT PUT when
the value is unchanged from what GET /model returned.
Critical:
- ExternalConnectModal.tsx: filledUniversalMcp substitution searched
for WORKSPACE_AUTH_TOKEN but the snippet's placeholder is now
MOLECULE_WORKSPACE_TOKEN (changed in the previous polish commit
876c0bfc). Operators copy-pasting the MCP tab would have gotten a
literal "<paste from create response>" instead of the token. Fix
the substitution to match the new placeholder name.
Important:
- mcp_cli._platform_register: 401/403 from initial register now hard-
exits with code 3 + an actionable stderr message pointing the
operator at the canvas Tokens tab. Pre-fix: warning log + continue,
which made a bad-token startup silently fail (heartbeat 401's
forever, every tool call also 401's, no clear surfacing in the
operator's MCP client). 500/503 still log + continue (transient
platform blips shouldn't abort the MCP loop).
- a2a_mcp_server.cli_main docstring: removed stale claim that this is
the wheel's console-script entry-point target. The actual target is
mcp_cli.main since 2026-04-30. Wheel-smoke pins both names so the
functionality was correct, but the doc was lying.
Test coverage: 3 new mcp_cli tests:
- register 401 exits code=3 + stderr mentions canvas Tokens tab
- register 403 (C18 hijack rejection) takes same path
- register 500/503 does NOT exit — only auth errors hard-fail
Findings deferred to follow-up (acceptable per review rubric):
- Code dedup across mcp_cli / heartbeat.py / molecule_agent SDK
- Pooled httpx.Client for connection reuse
- Heartbeat exponential backoff
- Token-resolution ordering parity (env-first vs file-first)
between mcp_cli.main and platform_auth.get_token

The canvas tab snippet for the Universal MCP path was written before
this PR added the built-in register + heartbeat thread. Earlier wording
described it as "outbound-only — pair with the Claude Code or Python SDK
tab for heartbeat + inbound messages" — that's stale. molecule-mcp now
handles register + heartbeat itself; the only thing it doesn't yet do is
inbound A2A delivery.
Updated:
- externalUniversalMcpTemplate header comment + body — describes
standalone behavior, points operators at SDK/channel only when they
need INBOUND (not heartbeat).
- Drops the now-redundant curl-register step from the snippet — the
binary registers itself on startup.
- Canvas modal label likewise updated.
No runtime / behavior change; pure docs polish so a copy-pasting
operator's mental model matches what the binary actually does.
