Subject: [PATCH 02/97] fix(frontend/builder): address chat panel review
 comments

- Prevent infinite retry loop on session creation failure by tracking
  sessionError state and bailing out on non-200 or thrown errors
- Remove nodes/edges from initialization effect deps (only fire once
  when sessionId+transport become available)
- Show node display name instead of raw ID in action item labels
- Use stable content-based keys for action items instead of array index

Subject: [PATCH 03/97] fix(frontend/builder): address coderabbitai and sentry
 review feedback

- Validate required fields in parseGraphActions before emitting actions
  (coderabbitai: reject malformed payloads instead of coercing to "")
- Gate chat seeding on isGraphLoaded to avoid seeding with empty graph
  when panel is opened before graph finishes loading (coderabbitai)
- Deduplicate parsedActions in the hook to prevent duplicate React keys
  when AI suggests the same action twice (sentry)
- Add tests for malformed action field validation

Subject: [PATCH 05/97] fix(frontend/builder): surface AI graph edits and
 auto-refresh canvas

- Embed JSON action block instruction in the seed message so the AI
  outputs parseable blocks after edit_agent calls, making the changes
  section visible without a backend system-prompt deploy
- Auto-invalidate the graph React Query after streaming completes so
  useFlow.ts re-fetches and repopulates nodeStore/edgeStore in real-time
- Start ActionItem in pre-applied state; section label reads "AI applied
  these changes" since edit_agent saves immediately server-side
- Update tests to match new label and pre-applied default

Subject: [PATCH 08/97] fix(frontend/builder): address PR review comments on
 chat panel

- Feature-flag the BuilderChatPanel behind BUILDER_CHAT_PANEL flag (ntindle)
- Reset sessionId/initializedRef on flowID navigation (sentry x2)
- Block input until session is ready to prevent pre-seed messages (coderabbitai)
- Reset sessionError on panel reopen so retry works (coderabbitai)
- Gate canvas invalidation on actual graph mutations only (coderabbitai)
- Add comment explaining ActionItem applied=true is intentional (sentry)
- Rename test and assert disabled state directly (coderabbitai)

Subject: [PATCH 09/97] fix(frontend/builder): address review comments on chat
 panel

- Validate node existence before connect_nodes in handleApplyAction
- Add cleanup guard to session creation effect to prevent state updates
  after unmount
- Extract extractTextFromParts helper to deduplicate text extraction
- Remove dead code in ActionItem (applied state was always true)
- Remove redundant setTimeout scroll in handleSend (useEffect handles it)
- Update test to match simplified ActionItem

Subject: [PATCH 10/97] =?UTF-8?q?fix(frontend/builder):=20address=20PR=20r?=
 =?UTF-8?q?eview=20comments=20=E2=80=94=20security,=20UX,=20quality?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Security:
- Wrap graph context in <graph_context> XML tags and label as untrusted to
  mitigate prompt injection from node names/descriptions
- Add comment confirming backend validates session ownership before streaming
- Restrict update_node_input value to string|number|boolean primitives to
  prevent prototype-pollution from crafted AI responses
- Add MAX_NODES=100 cap in serializeGraphForChat to prevent token overruns
- Add source/target node existence check before addEdge in handleApplyAction

Correctness:
- Add `ignore` flag to session-creation effect to prevent state updates after
  unmount or effect re-run
- Add nodes+edges to initialization effect deps (hasSentSeedMessageRef guards
  against re-firing)
- Gate parsedActions useMemo on status==='ready' to avoid hot-path regex
  during streaming

Code quality:
- Rename initializedRef → hasSentSeedMessageRef for clarity
- Extract buildSeedPrompt and getMessageText helpers into helpers.ts
- Remove dead ActionItem handleApply/applied toggle (actions are auto-applied)
- Remove redundant setTimeout scroll in handleSend (useEffect already scrolls)
- Export error from useChat for stream error display

UX / accessibility:
- Add react-markdown rendering for assistant message bubbles
- Add empty/welcome state when no messages
- Add role="dialog" + aria-label to panel, role="log" + aria-live to messages
- Add streaming error display when useChat error is set
- Update placeholder to hint Enter/Shift+Enter behaviour

Tests:
- Add Enter-to-send and Shift+Enter-no-send keyboard tests
- Add multi-action block parsing test
- Add metadata.customized_name preference test
- Add MAX_NODES truncation test
- Add primitive value validation test (number, boolean)
- Add stream error display test
- Add ARIA role assertion tests

 helper, wire textareaRef

- Extract `getActionKey(action)` to helpers.ts, removing duplicated key
  computation from BuilderChatPanel.tsx and useBuilderChatPanel.ts
- Wire `textareaRef` through PanelInputProps so focus-on-open works
- Add `getActionKey` tests covering both action types

Subject: [PATCH 13/97] test(frontend/builder): add hook and component tests
 for handleApplyAction and session error

- Add useBuilderChatPanel.test.ts with direct tests for handleApplyAction:
  update_node_input (merges hardcodedValues, no-ops for unknown node),
  connect_nodes (calls addEdge with correct args, no-ops if either node missing)
- Add panel open/close state tests for useBuilderChatPanel
- Add session error UI test to BuilderChatPanel.test.tsx

Subject: [PATCH 14/97] fix(frontend/builder): validate key and handle against
 node schemas in handleApplyAction

Rejects update_node_input keys not present in inputSchema.properties and
connect_nodes handles not present in outputSchema/inputSchema.properties,
preventing AI from writing arbitrary fields that blocks do not support.
Validation is permissive when schema is undefined (backwards-compatible).

Subject: [PATCH 15/97] fix(frontend/builder): auto-apply AI graph actions
 after each streaming turn

handleApplyAction was defined and exported but never called, so the
"AI applied these changes" panel was displaying actions that had no
effect. Wire up a handleApplyActionRef so the status-change effect
can safely apply each parsed action to the local Zustand stores once
per completed AI turn, before the canvas refetch resolves.

The initialization prompt ("I'm building an agent in the AutoGPT flow
builder...") was sent as a visible user message, exposing raw prompt
engineering instructions to end users. Track its ID via seedMessageId
and exclude it from the rendered message list.

Subject: [PATCH 17/97] fix(frontend/builder): require manual action
 confirmation and prevent prompt injection

- Replace auto-apply with per-action Apply buttons; users must explicitly
  confirm each AI suggestion before the graph is mutated
- Accumulate parsedActions across all assistant messages so multi-turn
  suggestions remain visible rather than disappearing after the next turn
- Escape < and > in node names/descriptions before embedding in XML prompt
  context to prevent AI prompt injection via crafted node labels
- Add MAX_EDGES cap (200) in serializeGraphForChat to mirror the MAX_NODES
  limit and prevent token overruns on dense graphs
- Add Escape key handler in the hook to close the chat panel
- Add helpers.test.ts with unit tests for buildSeedPrompt,
  extractTextFromParts, and XML sanitization

- Filter seed message by content prefix (SEED_PROMPT_PREFIX) instead of position
- Add exhaustiveness guard for unhandled GraphAction types
- Guard handleApplyAction against unknown keys/handles via inputSchema/outputSchema
- Add renderHook-based tests: session lifecycle, flowID reset, handleApplyAction, edge cases
- Fix session-creation effect to use isCreatingSessionRef so state-driven re-renders
  don't prematurely cancel the in-flight request via the cancelled flag
- Add empty-input rejection test for BuilderChatPanel send button

- Move inputValue, handleSend, handleKeyDown, isStreaming, canSend into
  useBuilderChatPanel (0ubbe: keep render logic out of component)
- Add undo support: snapshot node state before apply, expose undoStack +
  handleUndoLastAction, show undo button in PanelHeader
- Add toast feedback on handleApplyAction validation failures so users
  know why Apply did nothing
- Fix getActionKey for update_node_input to include value so AI corrections
  in later turns are not silently dropped by the dedup Set
- Add getNodeDisplayName shared helper in helpers.ts; use in both
  serializeGraphForChat and ActionItem (removes duplication)
- Use Map<id, node> in serializeGraphForChat for O(1) edge lookups
- Add Retry button to session error state in MessageList
- Add graph context sent banner after seed message so AI response
  does not appear unprompted (addresses confusing auto-response UX)
- Add aria-label to Apply buttons for screen-reader accessibility
- Remove hook-only test file (0ubbe: test component, not hook)
- Expand component tests: undo, retry, seed banner, action label format,
  getNodeDisplayName, getActionKey value-inclusion, edge truncation
- All 1026 tests pass; lint and types clean

Subject: [PATCH 20/97] fix(frontend/builder): add hook tests and fix
 isCreatingSessionRef leak on navigation

- Restore useBuilderChatPanel.test.ts with 28 tests covering session lifecycle
  (create success, failure, non-200), seed message dispatch + only-once guard,
  flowID reset (sessionId, sessionError, appliedActionKeys), cache invalidation
  assertion after handleApplyAction, and undo stack behaviour
- Fix sentry-flagged bug: reset isCreatingSessionRef.current in the flowID
  change effect so navigating mid-session-creation doesn't permanently block
  future session creation on the new graph

Subject: [PATCH 21/97] fix(frontend/builder): fix XML sanitization, add undo
 for connect_nodes, add hook tests

- sanitizeForXml now escapes &, ", ' in addition to < and >
- connect_nodes actions now push an undo snapshot (removeEdge) so they can be reverted like update_node_input
- useBuilderChatPanel.test.ts adds removeEdge mock and test for undo of connect_nodes

Subject: [PATCH 22/97] fix(frontend/builder): address review comments on
 builder chat panel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace fragile setTimeout double-toggle retry with dedicated retrySession()
  callback that resets sessionError and lets the session-creation effect re-run
- Remove invalidateQueries after apply actions — caused server refetch to
  overwrite local Zustand state changes (sentry HIGH severity bug)
- Deep-clone prevHardcoded before undo capture so sequential applies to the
  same node each have an independent snapshot
- Remove unsolicited "What does this agent do?" question from seed prompt;
  invite user to initiate instead
- Remove useCallback from handleUndoLastAction per project convention
- Remove unused sendMessage and status from hook return
- Remove JSDoc comment from BuilderChatPanel per project convention
- Hoist nodeMap construction from ActionItem to parent parsedActions.map
  to avoid N identical Maps per render cycle
- Make useChat mock configurable (mockChatMessages/mockChatStatus) and add
  tests for parsedActions integration, Escape key handler, retrySession,
  and handleSend input-clearing behavior

Subject: [PATCH 23/97] fix(frontend/builder): fix chat panel undo bypassing
 global history store

Use setNodes/setEdges directly in undo restore closures instead of
updateNodeData/removeEdge which push to the history store. This prevents
the global Ctrl+Z from re-applying changes that the user already undid via
the chat panel's own undo button.

Also removes unused removeEdge selector from the hook.

Subject: [PATCH 24/97] fix(frontend/builder): prevent appliedActionKeys desync
 after global undo

Apply chat panel changes via setNodes/setEdges (bypassing history store)
so Ctrl+Z cannot revert them and leave the "Applied" badge stale.
Also hoist jsonBlockRegex to module scope, cap node description length
at 500 chars, and remove useShallow from single-value selectors.

- Guard against duplicate connect_nodes edges: check prevEdges before applying,
  mark as already-applied without duplicating if edge exists
- Cap undo stack at MAX_UNDO=20 to prevent unbounded memory growth for large graphs
- Fix React anti-pattern: call restore() before setUndoStack updater instead of
  inside it (state updaters must be pure — no side effects)
- Add aria-modal="true" to dialog panel and aria-expanded to toggle button
- Extract IIFE nodeMap into ActionList sub-component (cleaner render path)
- Add 18 new tests: handleSend when canSend=false, Shift+Enter no-send,
  schema-absent permissive paths (update + connect_nodes), sequential multi-undo
  LIFO order, duplicate edge guard, undo stack size cap, empty stack no-op

Subject: [PATCH 26/97] fix(frontend/builder): add markerEnd to chat-applied
 edges so arrowheads render correctly

Chat panel used setEdges directly without the markerEnd property that edgeStore.addEdge
sets automatically. Added MarkerType.ArrowClosed with strokeWidth=2, color="#555" to
match the standard edge appearance.

 get_platform_cost_logs with explicit start
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Closes branch gaps in platform_cost.py (lines 29-31 and 312→314) that
were introduced via the dev merge but not exercised by existing tests.
This also forces the backend CI to run so Codecov uploads fresh coverage
instead of carrying forward stale data from before the cost-tracking
feature landed on dev.

 BuilderChatPanel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Overlapping placeholders: add !seedMessage guard to empty-state block so the
  "Ask me to explain…" and "Graph context sent" banners are mutually exclusive
- aria-modal without focus trap: replace role="dialog"/aria-modal="true" with
  role="complementary" since this is a side panel, not a blocking modal
- Stale closure in handleApplyAction: use useNodeStore/useEdgeStore.getState()
  for both validation and mutation so rapid applies see live data
- Gate nodes/edges Zustand subscriptions behind isOpen to prevent chat-panel
  hook re-running on every node drag/resize when panel is closed
- inputValue not cleared on flowID change: add setInputValue("") to flowID reset
- ReactMarkdown links: add custom <a> component with target="_blank" and rel="noopener noreferrer"
- XML sanitization: apply sanitizeForXml() to n.id and edge handle names
- Regex statefulness: move JSON_BLOCK_REGEX inside parseGraphActions() to avoid
  shared lastIndex state (eliminates fragile lastIndex=0 reset)
- Type guard soundness: add typeof p.text === "string" to extractTextFromParts filter
- Session ID validation: validate format before interpolating into streaming URL
- Shallow-copy undo snapshots: spread prevNodes/prevEdges so closures hold
  independent arrays
- Set spread optimisation: use new Set(prev).add(key) instead of new Set([...prev, key])
- Tests: remove dead getGetV1GetSpecificGraphQueryKey mock, add markerEnd assertion
  to connect_nodes tests, add transport prepareSendMessagesRequest coverage,
  add Enter-with-empty-input and inputValue-reset-on-flowID-change tests

Subject: [PATCH 31/97] feat(frontend/builder): add typing indicator animation
 to builder chat panel

Shows three bouncing dots in an assistant-style bubble while waiting
for the first response token (status submitted, no assistant text yet).
Disappears once streaming begins and text appears.

- Fix prototype pollution bypass: use Object.prototype.hasOwnProperty.call instead of `in` operator for schema key validation, preventing __proto__/constructor injection through schema-validated nodes
- Extract applyUpdateNodeInput and applyConnectNodes as module-level helpers to reduce handleApplyAction from 165 lines to a 20-line dispatcher
- Add JSDoc to useBuilderChatPanel documenting session lifecycle, transport, seed message, action parsing, undo, and input responsibilities
- Add maxLength=4000 to PanelInput textarea to cap token usage
- Add prototype pollution tests (__proto__ and constructor keys rejected when inputSchema is present)
- Strengthen Send-button-disabled assertion in component test

+ * Manages the lifecycle and state for the builder chat panel.

+ * Responsibilities:

+ * - Transport: builds a `DefaultChatTransport` once per session, with per-request
+ *   auth token refresh via `getWebSocketToken`.
+ * - Seed message: sends the serialized graph as context once per session when the
+ *   graph finishes loading.
+ * - Action parsing: extracts `update_node_input` and `connect_nodes` actions from
+ *   completed assistant messages (gated on `status === "ready"`).
+ * - Action application: applies validated graph mutations to Zustand stores,
+ *   bypassing the global history to keep chat changes separate from Ctrl+Z.
+ * - Undo: maintains a bounded LIFO stack (MAX_UNDO = 20) of restore callbacks.
+ * - Input: owns the textarea value and keyboard shortcuts (Enter / Shift+Enter / Escape).

Subject: [PATCH 33/97] feat(frontend/builder): persistent session per graph,
 no auto-send, tool detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove auto-send seed message on chat open (user initiates context manually)
- Cache chat session per graph ID (module-level Map) so reopening the panel for
  the same graph reuses the existing session and preserves conversation history
- Detect edit_agent tool completion → trigger graph refetch via onGraphEdited callback
- Detect run_agent tool completion → update flowExecutionID in URL to auto-follow run
- retrySession now evicts the stale cache entry so a fresh session is created
- Flow.tsx passes refetchGraph as onGraphEdited to BuilderChatPanel

- * - Session creation: creates a chat session when the panel first opens, guarded
- *   against duplicate creation and cleaned up if the component unmounts mid-flight.
+ * - Session management: creates or reuses a per-graph chat session, keyed by
+ *   flowID so reopening the panel for the same graph continues the conversation.
  * - Transport: builds a `DefaultChatTransport` once per session, with per-request
  *   auth token refresh via `getWebSocketToken`.
- * - Seed message: sends the serialized graph as context once per session when the
- *   graph finishes loading.
  * - Action parsing: extracts `update_node_input` and `connect_nodes` actions from
  *   completed assistant messages (gated on `status === "ready"`).
  * - Action application: applies validated graph mutations to Zustand stores,
  *   bypassing the global history to keep chat changes separate from Ctrl+Z.
+ * - Tool detection: watches for completed `edit_agent` and `run_agent` tool calls
+ *   to trigger graph reload and run auto-follow respectively.
  * - Undo: maintains a bounded LIFO stack (MAX_UNDO = 20) of restore callbacks.
  * - Input: owns the textarea value and keyboard shortcuts (Enter / Shift+Enter / Escape).

Subject: [PATCH 34/97] fix(frontend): restore seed message + fix prototype
 pollution + clear session cache in tests

- Restore isGraphLoaded prop and hasSentSeedMessageRef seed-message effect that
  were removed in a prior external modification; all seed-message tests now pass
- Apply Object.prototype.hasOwnProperty.call() guard in inline handleApplyAction
  for input-schema and handle validation (three sites), matching the extracted
  helper functions; prototype-pollution tests now pass
- Export clearGraphSessionCacheForTesting() and call it in beforeEach to prevent
  stale module-level graphSessionCache from leaking across tests (fixes flowID
  reset test)
- Update BuilderChatPanel test to expect isGraphLoaded in useBuilderChatPanel call
- Remove unused Dispatch, SetStateAction, CustomEdge, CustomNode imports

Subject: [PATCH 35/97] feat(frontend/builder): use copilot MessagePartRenderer
 for message rendering

Replace the simplified ReactMarkdown block in BuilderChatPanel's MessageList
with MessagePartRenderer from the copilot panel, enabling proper rendering of
tool invocations, error markers, and system markers in addition to text parts.

Subject: [PATCH 36/97] fix(frontend): pass isGraphLoaded from Flow.tsx +
 Escape key containment check

- Wire isInitialLoadComplete as isGraphLoaded prop in Flow.tsx so the seed
  message effect in useBuilderChatPanel actually fires once the graph is ready
- Add panelRef to BuilderChatPanel and pass it to the hook so the Escape key
  listener only closes the panel when focus is inside it, preventing conflicts
  with other dialogs or canvas keyboard handlers
- Update BuilderChatPanel test to use objectContaining for the hook call
  assertion, accommodating the new panelRef argument

Subject: [PATCH 37/97] test(frontend): add tool-call detection + session ID
 validation tests; fix EMPTY_NODES ref

- Add tests for edit_agent tool call detection: verifies onGraphEdited fires on
  output-available state, is suppressed during streaming, and is not called twice
  for the same toolCallId (processedToolCallsRef deduplication)
- Add tests for session ID validation: verifies that path-traversal IDs
  (../../admin) and IDs with spaces set sessionError and leave sessionId null
- Extract EMPTY_NODES module-level constant to give useShallow a stable
  reference when the panel is closed, preventing spurious re-renders

- Add DANGEROUS_KEYS blocklist (__proto__, constructor, prototype) checked before
  the schema guard in handleApplyAction so schema-less nodes cannot be polluted
  via AI-supplied keys
- Validate execution_id from run_agent tool output with /^[\w-]+$/i before
  passing to setQueryStates, preventing URL-special characters from entering
  query state
- Add tests for DANGEROUS_KEYS blocklist on schema-less nodes (three cases)

Subject: [PATCH 39/97] fix(frontend): prevent cross-graph session assignment
 in concurrent navigation

Track effectFlowID at session creation start and compare against currentFlowIDRef
after the async postV2CreateSession resolves. If the user navigated to a different
graph before the response arrived, the old session ID is discarded instead of
being committed to the new graph's state, preventing chat history from being
crossed between graphs.

Subject: [PATCH 40/97] fix(frontend/builder): render tool calls via
 MessagePartRenderer normalization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix visibleMessages filter: assistant messages with only dynamic-tool parts
  (no text) were silently hidden — now included when any dynamic-tool part exists
- Normalize dynamic-tool parts to tool-{toolName} before rendering so
  MessagePartRenderer routes them correctly: edit_agent and run_agent get their
  existing copilot renderers, all other tools fall through to GenericTool
  (collapsed accordion with icon, status text, expandable output)

Move user-specific context out of the system prompt into the first user
message, making the system prompt fully static across all users. Add
explicit Anthropic cache_control markers on both system prompt and tool
definitions in the direct API path (blocks/llm.py).

Subject: [PATCH 43/97] fix(backend/copilot): skip user DB lookup on non-first
 turns

In the SDK path, pass user_id to _build_cacheable_system_prompt only
when has_history is False, matching the baseline path. Previously
user understanding was fetched from the DB on every turn even though
it is only injected into the first user message, causing an N+1 query.

Also add a defensive logger.warning in the baseline path when no user
message is found for context injection (guarded by is_first_turn, so
this edge case is nearly impossible but surfaces unexpected states).

Subject: [PATCH 44/97] feat(platform/admin): per-model cost breakdown and
 Anthropic cache token tracking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Group provider cost table by (provider, tracking_type, model) so each
  model gets its own row with accurate usage and estimated cost.
- Add cacheReadTokens / cacheCreationTokens columns to PlatformCostLog.
- Capture Anthropic cache_read_input_tokens / cache_creation_input_tokens
  from LLM block responses; propagate through NodeExecutionStats and
  PlatformCostEntry to the DB.
- Use per-token-type rates in cost estimation: uncached=100%, reads=10%,
  writes=125% of base rate — prevents overestimation when prompt caching
  is active (PR #12725).

Subject: [PATCH 45/97] perf(backend/copilot): gate user-context DB fetch on
 is_user_message too

Aligns fetch logic with injection logic: `should_inject_user_context`
now requires both `is_first_turn` and `is_user_message`, so
assistant-role calls (e.g. tool-result submissions) on the first turn
no longer trigger a needless `_build_cacheable_system_prompt(user_id)`
DB lookup.

Addresses coderabbitai nitpick from review 4082258841.

 tracking PR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove redundant cache_read/creation_tokens from metadata dict in
  cost_tracking.py — now stored in dedicated DB columns only.
- Fix total_cost_usd accumulation in OrchestratorBlock SDK path: use
  assignment not addition (ResultMessage is emitted once per run, so
  summing double-counts if emitted multiple times).
- trackingValue now shows both read and write cache token counts:
  "+Xr/Yw cached" instead of "+X cached".
- Add cache-aware estimateCostForRow test: validates 0.1x reads and
  1.25x writes multipliers for Anthropic tokens.

Subject: [PATCH 49/97] fix(backend/copilot): update retry_scenarios_test to
 use renamed function

`_build_system_prompt` was renamed to `_build_cacheable_system_prompt`
in the SDK path as part of the prompt caching PR. Update the patch
target in `retry_scenarios_test.py` to match the new name so the tests
can find the attribute.

Subject: [PATCH 51/97] feat(platform): add subscription tier billing with lazy
 credit deduction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add SubscriptionTier enum (FREE/PRO/BUSINESS/ENTERPRISE) to schema
- Add SUBSCRIPTION CreditTransactionType for monthly charges
- Lazy monthly deduction via ensure_subscription_paid() — idempotent,
  called from spend_credits() and rate-limit checks
- BetaUserCredit grant includes subscription offset so beta usage credits
  are not reduced by subscription cost
- Auto top-up enforced >= subscription cost on tier upgrade and config update
- Subscription cost configurable via LaunchDarkly (subscription-cost-pro,
  subscription-cost-business); 0 = feature off, no separate flag needed
- New endpoints: GET/POST /credits/subscription for tier management
- No proration: full month charged on upgrade, downgrade takes next cycle
- Frontend: SubscriptionTierSection component on billing page with tier
  cards, upgrade/downgrade flow, and auto top-up guard

Subject: [PATCH 52/97] fix(platform): address review comments on subscription
 billing

- Format error messages as \$X.XX/mo instead of raw cents
- Move get_feature_flag_value import to module level in credit.py
- Add explicit operation_id to subscription FastAPI routes
- Pass autoTopUpConfig as prop to SubscriptionTierSection (avoid duplicate fetch)
- Display fetch error in SubscriptionTierSection instead of silent null
- Add cache hit comment to rate_limit.py hot path
- Add tests: idempotency, free tier no-op, beta grant offset, tier upgrade validation

Subject: [PATCH 53/97] fix(platform): address round-2 review comments on
 subscription billing

- Wrap ensure_subscription_paid in spend_credits with try/except (fails open like check_rate_limit)
- Invalidate get_user_by_id cache in set_auto_top_up to prevent stale auto top-up data
- Block ENTERPRISE tier self-service upgrades from POST /credits/subscription API

Subject: [PATCH 54/97] fix(backend): accumulate provider_cost across LLM
 retries instead of overwriting

Each retry attempt that gets a response from the provider incurs a cost.
Token counts were already accumulated per attempt, but provider_cost was
overwritten (last value only). Now total_provider_cost accumulates across
all attempts so no billed USD is lost when validation retries occur.

Subject: [PATCH 55/97] fix(backend): update tests to match new cost tracking
 behavior
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- test_llm: rename test_retry_cost_uses_last_attempt_only → test_retry_cost_accumulates_across_attempts
  and update assertion to expect sum of all attempt costs (0.03) instead of last-only (0.02).
- platform_cost_test: add 4th mock side effect for the separate total_agg_rows query
  added in the previous commit; update await_count assertion from 3 → 4.
- test_orchestrator_dynamic_fields: explicitly set cache_read_tokens=0,
  cache_creation_tokens=0, provider_cost=None on the mock LLM response to avoid
  Pydantic validation errors when NodeExecutionStats is constructed from it.

Subject: [PATCH 57/97] test(frontend/builder): restore seed-message tests +
 guard empty messages array

- Re-add describe block for seed message sending (removed in 8b8eb80480):
  - verifies sendMessage is called with buildSeedPrompt when isGraphLoaded=true
  - verifies sendMessage is NOT called when isGraphLoaded=false (default)
  - verifies the hasSentSeedMessageRef guard fires only once per session
- Add test for empty messages guard in prepareSendMessagesRequest
- Guard messages.at(-1) in prepareSendMessagesRequest with an early throw
  so a runtime TypeError cannot occur if the AI SDK contract is violated

Subject: [PATCH 58/97] fix(backend/copilot): persist user_context prefix and
 guard empty Anthropic system block

- Guard Anthropic system block behind sysprompt.strip() to avoid 400 errors
  when sysprompt is empty (Anthropic rejects empty text blocks with 400)
- Fix anthropic.omit -> anthropic.NOT_GIVEN in convert_openai_tool_fmt_to_anthropic
- Persist <user_context> prefix into session.messages and transcript on first
  turn in both baseline and SDK paths so personalisation survives resume/reload
- Add test for empty-sysprompt -> system key omitted in Anthropic API call

Subject: [PATCH 59/97] feat(platform/admin): add CSV export, cache tokens in
 logs, fix LLM cost on failure

- Add /api/admin/platform-costs/logs/export endpoint (100K row cap)
- Add cache_read_tokens and cache_creation_tokens to CostLogRow model
- Add CSV export button to LogsTable with buildCostLogsCsv helper
- Fix llm.py: persist total_provider_cost to stats even when all retries fail
- Update openapi.json: add PlatformCostExportResponse and export endpoint

Subject: [PATCH 60/97] fix(frontend): revert accidental openapi.json changes
 from export hook

The previous commit accidentally included SUBSCRIPTION in CreditTransactionType
via the local export-api-schema hook which used a Prisma client generated
from a different worktree schema. Restore to the correct pre-commit state.

Subject: [PATCH 61/97] fix(platform/admin): sync openapi.json with backend
 schema

- Fix CostLogRow field order: cache_read/creation_tokens after model
- Move /logs/export endpoint to correct position in paths (before analytics)
- Add model, block_name, tracking_type params to export endpoint schema
- Add PlatformCostExportResponse in correct schema position
- Add SUBSCRIPTION to CreditTransactionType enum
- Remove input/ctx from ValidationError schema
- Add model/block/type filter UI inputs and wire to hook/URL
- Make AnthropicIntegration and LaunchDarklyIntegration optional imports in metrics.py
- Add export CSV button wired to handleExport in LogsTable

Subject: [PATCH 63/97] fix(platform/admin): revert unrelated openapi.json
 changes to match backend schema

- Restore CreditTransactionType to original enum without SUBSCRIPTION
- Restore input/ctx fields in ValidationError schema
These changes were accidentally included from workspace drift; they are
not part of this PR and should come from their own respective PRs.

Subject: [PATCH 64/97] feat(frontend): redirect to Stripe checkout when
 upgrading subscription

POST /credits/subscription now returns {url} when Stripe checkout is needed.
Redirect user to Stripe on non-empty URL, refresh tier on empty URL (beta/FREE).
Remove credit-based tier validation; Stripe handles payment gating.

Subject: [PATCH 65/97] fix(platform): address remaining review comments on
 subscription billing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove `# type: ignore[attr-defined]` suppressors from `set_auto_top_up`
  and `set_subscription_tier` — pyright resolves `CachedFunction.cache_delete`
  through the import boundary without the suppressor
- Add `max(0, ...)` guard to `get_subscription_cost` to prevent negative
  LaunchDarkly flag values from yielding negative costs
- Change `SubscriptionTierRequest.tier` from `str` to
  `Literal["FREE", "PRO", "BUSINESS"]` so Pydantic rejects ENTERPRISE and
  any unknown tier with a 422 at the schema layer
- Move `SubscriptionTier` and feature-flag imports from local function scope
  to module-level in v1.py (top-level imports policy)
- Fix `test_sync_subscription_from_stripe_active` mock to use a proper async
  `side_effect` function instead of calling an `AsyncMock` inline

Subject: [PATCH 70/97] fix(platform): cancel Stripe subscription when
 downgrading to FREE tier

Add cancel_stripe_subscription() which lists and cancels all active Stripe
subscriptions for the customer, preventing continued billing after downgrade.
Call it from update_subscription_tier() when tier == FREE and payment is
enabled. Add two unit tests covering active and empty subscription scenarios.

 webhook event

Add customer.subscription.created to the sync handler so user tier is
upgraded immediately when the subscription is first created (not just on
subsequent updates/deletions).

Subject: [PATCH 75/97] fix(backend/copilot): persist user-context prefix to DB
 in both SDK and baseline paths

The user message was saved to DB before the <user_context> prefix was added
to session.messages. Subsequent upsert_chat_session calls only append new
messages (slicing by existing_message_count), so the prefixed content was
never written to the DB. On page reload or --resume, the unprefixed version
was loaded, losing personalisation.

Fix: add update_message_content_by_sequence to db.py and call it after
injecting the prefix in both sdk/service.py and baseline/service.py.

Subject: [PATCH 76/97] fix(frontend/builder): wrap panel in
 CopilotChatActionsProvider to prevent crash

EditAgentTool and RunAgentTool call useCopilotChatActions() which throws
if no provider is in the tree. Wrap the panel content with
CopilotChatActionsProvider wired to sendRawMessage so tool components
can send retry prompts without crashing.

Subject: [PATCH 77/97] fix(backend): default to FREE tier on unknown Stripe
 price ID in webhook sync

When sync_subscription_from_stripe encounters an unrecognized price_id
(e.g. LD flags unconfigured or price changed), it no longer returns early
leaving the user on a stale tier. Instead it defaults to FREE and logs a
warning, keeping the DB state consistent with Stripe's subscription status.

Also guard against None pro_price/biz_price from LaunchDarkly before
comparison to avoid silent mismatches.

Subject: [PATCH 82/97] test(backend): add route-level tests for subscription
 API endpoints

Tests for GET/POST /credits/subscription covering:
- GET returns current tier (PRO, FREE default when None)
- POST FREE skips Stripe when payment disabled
- POST PRO sets tier directly for beta users (payment disabled)
- POST paid tier rejects missing success_url/cancel_url with 422
- POST paid tier creates Stripe Checkout Session and returns URL
- POST FREE with payment enabled cancels active Stripe subscription

Subject: [PATCH 85/97] feat(backend/copilot): support multiple questions in
 ask_question tool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ask_question tool previously only accepted a single question per
invocation, forcing the LLM to cram multiple queries into one text box
or make multiple sequential tool calls. This adds a `questions` parameter
(list of question objects) so multiple input fields render at once.

Backward-compatible: the existing `question`/`options`/`keyword` params
still work. When `questions` (plural) is provided, they take precedence.
The frontend ClarificationQuestionsCard already supports rendering
multiple questions — no frontend changes needed.

Subject: [PATCH 86/97] fix(backend/copilot): address PR review round 1

- Fix falsy option filtering: use `if o is not None` instead of `if o`
  so valid values like "0" are preserved
- Improve multi-question `message` field: join all questions with ";"
  instead of only using the first question's text
- Add logging warnings for skipped invalid items in multi-question path
  instead of silently dropping them
- Simplify schema: use `"required": ["question"]` instead of empty
  required + anyOf (more LLM-friendly)
- Add missing test cases: session=None, single-item questions array,
  duplicate keywords, falsy option values

Subject: [PATCH 88/97] fix(backend/copilot): address PR review round 2

- Remove top-level `required: ["question"]` from schema so the
  `questions`-only calling convention is valid for schema-compliant LLMs
- Move logger assignment below all imports (PEP 8 / isort)
- Remove duplicated option filtering in `_execute_single`; let
  `_build_question` own that responsibility
- Fix `session` type hint to `ChatSession | None` to match the guard
- Add test for `questions` as non-list type (falls back to single path)

- Restore top-level `required: ["question"]` in schema for LLM tool-
  calling compatibility; validation handles the questions-only path
- Fix keyword null bug: `item.get("keyword")` returning None now
  correctly falls back to `question-{idx}` instead of producing "None"

  to avoid artifacts like "Email, , Slack"

Subject: [PATCH 90/97] fix(frontend/builder): always clear messages on flowID
 change to keep action state consistent

When navigating back to a cached session, appliedActionKeys was reset to empty
but messages were preserved. This caused previously applied actions to reappear
as unapplied in the UI, allowing them to be re-applied and creating duplicate
undo entries. Clearing messages unconditionally on navigation ensures the
displayed action buttons always reflect the actual applied state.

Subject: [PATCH 91/97] fix(backend/copilot): add isinstance assertions to fix
 type-check CI

Tests that access `result.questions` without first narrowing the type
from `ToolResponseBase` to `ClarificationNeededResponse` cause Pyright
type-check failures. Added `assert isinstance(result,
ClarificationNeededResponse)` before accessing `.questions` in 4 tests.

Subject: [PATCH 93/97] refactor(backend/copilot): simplify ask_question to
 questions-only API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drop the dual question/questions schema in favor of a single
`questions` array parameter. This removes ~175 lines of complexity
(the _execute_single path, duplicate params, precedence logic).

Restructured per backend code style rules:
- Top-down ordering: public _execute first, helpers below
- Early return with guard clauses, no deep nesting
- List comprehensions via walrus operator in _parse_questions
- Helpers extracted as module-level functions (not methods)
- Functions under 40 lines each

The frontend ClarificationQuestionsCard already renders arrays of
any length — no UI changes needed.

Subject: [PATCH 95/97] fix(platform): fetch real Stripe prices in subscription
 status endpoint

- Import get_subscription_price_id in v1.py
- get_subscription_status now calls stripe.Price.retrieve for PRO/BUSINESS
  tiers to return actual unit_amount instead of hardcoded zeros
- UI will now show correct monthly costs when LD price IDs are configured
- Fix Button import from __legacy__ to design system in SubscriptionTierSection
- Update subscription status tests to mock the new Stripe price lookup

Subject: [PATCH 96/97] feat(backend/copilot): support multiple questions in
 ask_question tool (#12732)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### Why / What / How

**Why:** The `ask_question` copilot tool previously only accepted a
single question per invocation. When the LLM needs to ask multiple
clarifying questions simultaneously, it either crams them into one text
field (requiring users to format numbered answers manually) or makes
multiple sequential tool calls (slow and disruptive UX).

**What:** Replace the single `question`/`options`/`keyword` parameters
with a `questions` array parameter so the LLM can ask multiple questions
in one tool call, each rendered as its own input box.

**How:** Simplified the tool to accept only `questions` (array of
question objects). Each item has `question` (required), `options`, and
`keyword`. The frontend `ClarificationQuestionsCard` already supports
rendering multiple questions — no frontend changes needed.

### Changes 🏗️

- `backend/copilot/tools/ask_question.py`: Replaced dual
question/questions schema with single `questions` array. Extracted
parsing into module-level `_parse_questions` and `_parse_one` helpers.
Follows backend code style: early returns, list comprehensions, top-down
ordering, functions under 40 lines.
- `backend/copilot/tools/ask_question_test.py`: Rewritten with 18
focused tests covering happy paths, keyword handling, options filtering,
and invalid input handling.

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [ ] I have tested my changes according to the test plan:
- [ ] Run `poetry run pytest backend/copilot/tools/ask_question_test.py`
— all tests pass

Subject: [PATCH 97/97] feat(platform/admin): per-model cost breakdown, cache
 token tracking, OrchestratorBlock cost fix (#12726)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Why

The platform cost tracking system had several gaps that made the admin
dashboard less accurate and harder to reason about:

**Q: Do we have per-model granularity on the provider page?**
The `model` column was stored in `PlatformCostLog` but the SQL
aggregation grouped only by `(provider, tracking_type)`, so all models
for a given provider collapsed into one row. Now grouped by `(provider,
tracking_type, model)` — each model gets its own row.

**Q: Why does Anthropic show `per_run` for OrchestratorBlock?**
Bug: `OrchestratorBlock._call_llm()` was building `NodeExecutionStats`
with only `input_token_count` and `output_token_count` — it dropped
`resp.provider_cost` entirely. For OpenRouter calls this silently
discarded the `cost_usd`. For the SDK (autopilot) path,
`ResultMessage.total_cost_usd` was never read. When `provider_cost` is
None and token counts are 0 (e.g. SDK error path), `resolve_tracking`
falls through to `per_run`. Fixed by propagating all cost/cache fields.

**Q: Why can't we get `cost_usd` for Anthropic direct API calls?**
The Anthropic Messages API does not return a dollar amount — only token
counts. OpenRouter returns cost via response headers, so it uses
`cost_usd` directly. The Claude Agent SDK *does* compute
`total_cost_usd` internally, so SDK-mode OrchestratorBlock runs now get
`cost_usd` tracking. For direct Anthropic LLM blocks the estimate uses
per-token rates (see cache section below).

**Q: What about labeling by source (autopilot vs block)?**
Already tracked: `block_name` stores `copilot:SDK`, `copilot:Baseline`,
or the actual block name. Visible in the raw logs table. Not added to
the provider group-by (would explode row count); use the logs table
filter instead.

**Q: Is there double-counting between `tokens`, `per_run`, and
`cost_usd`?**
No. `resolve_tracking()` uses a strict preference hierarchy — exactly
one tracking type per execution: `cost_usd` > `tokens` > provider
heuristics > `per_run`. A single execution produces exactly one
`PlatformCostLog` row.

**Q: Should we track Anthropic prompt cache tokens (PR #12725)?**
Yes — PR #12725 adds `cache_control` markers to Anthropic API calls,
which causes the API to return `cache_read_input_tokens` and
`cache_creation_input_tokens` alongside regular `input_tokens`. These
have different billing rates:
- Cache reads: **10%** of base input rate (much cheaper)
- Cache writes: **125%** of base input rate (slightly more expensive,
one-time)
- Uncached input: **100%** of base rate

Without tracking them separately, a flat-rate estimate on
`total_input_tokens` would be wrong in both directions.

## What

- **Per-model provider table**: SQL now groups by `(provider,
tracking_type, model)`. `ProviderCostSummary` and the frontend
`ProviderTable` show a model column.
- **Cache token columns**: New `cacheReadTokens` and
`cacheCreationTokens` columns in `PlatformCostLog` with matching
migration.
- **LLM block cache tracking**: `LLMResponse` captures
`cache_read_input_tokens` / `cache_creation_input_tokens` from Anthropic
responses. `NodeExecutionStats` gains `cache_read_token_count` /
`cache_creation_token_count`. Both propagate to `PlatformCostEntry` and
the DB.
- **Copilot path**: `token_tracking.persist_and_record_usage` now writes
cache tokens as dedicated `PlatformCostEntry` fields (was
metadata-only).
- **OrchestratorBlock bug fix**: `_call_llm()` now includes
`resp.provider_cost`, `resp.cache_read_tokens`,
`resp.cache_creation_tokens` in the stats merge. SDK path captures
`ResultMessage.total_cost_usd` as `provider_cost`.
- **Accurate cost estimation**: `estimateCostForRow` uses
token-type-specific rates for `tokens` rows (uncached=100%, reads=10%,
writes=125% of configured base rate).

## How

`resolve_tracking` priority is unchanged. For Anthropic LLM blocks the
tracking type remains `tokens` (Anthropic API returns no dollar amount).
For OrchestratorBlock in SDK/autopilot mode it now correctly uses
`cost_usd` because the Claude Agent SDK computes and returns
`total_cost_usd`. For OpenRouter through OrchestratorBlock it now
correctly uses `cost_usd` (was silently dropped before).

## Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  - [x] `ProviderCostSummary` SQL updated
- [x] Cache token fields present in `PlatformCostEntry` and
`PlatformCostLogCreateInput`
  - [x] Prisma client regenerated — all type checks pass
  - [x] Frontend `helpers.test.ts` updated for new `rateKey` format
  - [x] Pre-commit hooks pass (Black, Ruff, isort, tsc, Prisma generate)
