 - New CSS modules or ad hoc CSS when Tailwind utilities and Dify tokens cover the need.
 - Component-level plain `.css` files or component CSS imported through `globals.css`; use scoped `*.module.css` only when Tailwind and component variants cannot express the style.
 - Generic color utilities where Dify semantic tokens exist.
-- Hardcoded magic class values for colors, spacing, radius, shadow, z-index, or typography when Dify tokens, component variants, or documented radius mappings exist.

 - `!` important modifiers or important CSS overrides without a narrow, documented reason.
 - Manual class-list assembly through string concatenation, template strings, array `.join(' ')`, or a custom conditional combiner instead of `cn(...)`. Conditional values passed to `cn(...)` remain valid.
-- JS conditional class branches for primitive visual states already exposed by Dify UI/Base UI `data-*` selectors.

+# E2B runtime metering
+
+One ledger row represents one E2B `sandboxExecutionId`, from start/resume to
+pause/kill. Provider execution time and resource sizes determine compute usage;
+LLM token usage, message latency and local SDK-call duration do not.
+
+## Scheduled collection and boundaries
+
+The Dify API's existing Celery Beat schedule dispatches
+`schedule.collect_agent_sandbox_usage.collect_agent_sandbox_usage` every 60 seconds
+by default, through the existing `ops_trace` worker queue. The job calls
+`POST /internal/e2b/usage/collect` on the Agent backend using its existing Bearer
+service token and a `project_id` body. The E2B key stays in the Agent backend.
+
+The provider-specific endpoint performs one bounded scan, using request-scoped
+HTTP clients. It reads E2B lifecycle events and posts them to the Dify API's
+idempotent usage ingestion endpoint. It returns `{"completed": true}` only after
+all scanned pages and the checkpoint have been acknowledged. Partial scans return
+`completed=false`; provider/API errors fail this accounting request only.
+
+There is no Agent-process polling loop, Redis leader election, log outbox,
+observation worker, or requested/observed operation reporting. Generic leases,
+Agent runs, files, snapshots and binding lookups do not participate in metering.
+Their timing, cancellation handling and SDK retries retain their normal behavior.
+Metering misconfiguration is checked when collection is invoked, rather than
+becoming a prerequisite for business runtime startup or binding operations.
+
+The endpoint has a 240-second deadline. The scheduled HTTP caller has a
+260-second timeout, and the Celery task configures 270/300-second soft/hard limits.
+Pool support differs: gevent workers do not implement soft time limits, and
+blocking work cannot rely on their hard limit. The collection and HTTP deadlines
+are the primary bounds; verify the deployed worker pool before relying on Celery
+limits. See the [Celery time-limit documentation](https://docs.celeryq.dev/en/stable/userguide/workers.html#time-limits).
+Scheduled messages expire after one collection interval to avoid stale backlog.
+There is no automatic HTTP retry; future scheduled scans can redeliver provider
+IDs safely. Overlapping tasks may duplicate reads, but cannot multiply usage.
+
+## Data and attribution
+
+The API owns `agent_sandbox_usage_events` and `agent_sandbox_executions`.
+Ingestion persists provider facts and projects execution rows atomically; the
+execution key is `(provider, provider_project_id, provider_execution_id)`.
+A short project transaction lock protects ingestion. Binding creation/lookups do
+not register allocations, write accounting rows or acquire that lock.
+Steady-state usage-state reads do not take a project `FOR UPDATE` lock; activation
+can be initialized once when first needed.
+
+E2B's existing sandbox metadata contains binding, tenant, Agent and workspace
+identifiers. During background ingestion, optional attribution checks those IDs
+against the existing Binding → Workspace → App/Agent tenant-owned chain and the
+physical sandbox reference. It never trusts labels alone. Missing, malformed or
+already-deleted business records leave attribution unresolved while preserving
+complete project-level provider usage. A previously verified ownership snapshot
+survives later business deletion. Conflicting ownership is not silently reassigned.
+
+No accounting callback or transaction is added to the business path. There is no
+pre-create allocation journal. Older diagnostic/allocation columns and records
+are not destructively migrated in this revision; new accounting accepts only
+provider events and collector checkpoint/coverage-gap control records. Table
+retention is unchanged, with no new automatic cleanup policy.
+
+## Configuration
+
+Apply the existing usage-table migration before first enabling metering.
+Configure Dify API, Beat and the workers consuming `ops_trace` consistently:
+
+```dotenv
+AGENT_SANDBOX_METERING_ENABLED=true
+AGENT_SANDBOX_METERING_PROJECT_ID=<E2B project/team ID>
+AGENT_SANDBOX_METERING_START_AT=<whole-second UTC instant>
+AGENT_SANDBOX_METERING_INTERVAL_SECONDS=60
+```
+
+The task reuses `AGENT_BACKEND_BASE_URL` and `AGENT_BACKEND_API_TOKEN`; the
+existing SSRF-safe HTTP policy must permit that internal service. No E2B key is
+copied into API or worker configuration.
+
+Configure the Agent backend's one-shot endpoint:
+
+```dotenv
+DIFY_AGENT_SANDBOX_METERING_ENABLED=true
+DIFY_AGENT_E2B_PROJECT_ID=<same E2B project/team ID>
+DIFY_AGENT_SANDBOX_METERING_OVERLAP_SECONDS=900
+DIFY_AGENT_SANDBOX_METERING_FULL_SCAN_INTERVAL_SECONDS=3600
+DIFY_AGENT_SANDBOX_METERING_MAX_PAGES=1000
+```
+
+It reuses the existing E2B key, `DIFY_AGENT_API_TOKEN`, inner API URL and inner API
+key. The new endpoint requires a nonempty Bearer-token configuration even when
+legacy control-plane routes permit unauthenticated local development.
+`DIFY_AGENT_SANDBOX_METERING_POLL_INTERVAL_SECONDS` is no longer used: the interval
+belongs to Celery Beat on the API side. Both metering feature flags default off.
+
+Activation T0 is persisted and immutable. Only provider executions started at or
+after T0 are metered; starting before T0 and ending after it does not include an
+old execution. Resuming an older sandbox after T0 creates a new execution and is
+included. There is no historical backfill and no environment column; databases
+separate environments. A project ID also scopes and allowlists ingestion.
+
+## Failure semantics
+
+- Only complete provider terminal execution data populates metered duration. A
+  local `finally`, SDK expiry deadline or business success is not a billing clock.
+- Missing terminal fields remain pending; conflicts remain visible. Late starts
+  cannot reopen closed executions, and duplicate facts do not add duration twice.
+- Every scan starts provider offset pagination from zero, overlaps prior coverage
+  and periodically rescans the retained window. Failed, cancelled or page-bounded
+  scans never claim a completed checkpoint. SQL idempotency protects redelivery.
+- The assumed default provider event retention is seven days. Older uncovered
+  intervals are recorded as gaps rather than reconstructed or counted as zero.
+- A failed scheduled task affects accounting only. No accounting network request
+  is added to create/connect/pause/kill, lease helpers, runner or file operations.
+
+The API's private ingestion endpoints remain:
+`GET /inner/api/agent/sandbox-usage/state?project_id=...` and
+`POST /inner/api/agent/sandbox-usage/events`, authenticated with `X-Inner-Api-Key`.
+Event batches are limited to 100 records and 1 MiB, acknowledged after commit.
+They are for the isolated collector, not business-operation logging.
+
+## Querying usage
+
+For complete `quality='metered'` executions:
+
+```text
+sandbox_hours = sum(metered_duration_ms) / 3600000
+vcpu_hours = sum(metered_duration_ms * vcpu_count) / 3600000
+ram_gib_hours = sum(metered_duration_ms * memory_mib) / (3600000 * 1024)
+```
+
+Project totals include complete executions with unresolved attribution; report
+that count separately. Tenant/app reports require verified resolved attribution.
+For UTC windows `[A, B)`, clip execution intervals using start plus provider
+duration. Start time can have second precision, so cross-boundary allocation is
+not claimed to be millisecond-accurate; complete-window totals conserve duration.
+
+## Rollout checks
+
+1. Verify Beat's schedule, task registration and an existing worker consuming
+   `ops_trace`, along with image revisions, flags, project and immutable T0.
+2. Verify the authenticated one-shot endpoint, real scheduled execution and
+   advancing checkpoints. The Agent must not start a metering poller or leader.
+3. Keep a real business binding until collection resolves its owner, then retire
+   it and confirm previously copied accounting remains. Also verify complete
+   project usage for test sandboxes without business records.
+4. Exercise model success/failure/cancellation, files/list/read/download/errors,
+   snapshots/restoration and resource cleanup. Isolated bad accounting settings
+   or failing accounting-service stubs must not make business lookups fail.
+5. Compare physical execution IDs, duration and resources against actual E2B
+   events; replay scans/events and confirm totals do not increase.
+6. Verify old outbox and collector-leader keys are absent after deployment. Do
+   not alter run-store keys or stop shared services to inject accounting faults.
+
+Disable the metering flags and restart the relevant processes to stop collection;
+business runtime behavior remains the same. Keep the ledger and original T0.
+The independent stdout-only sandbox file-error fix is tracked separately from
+this accounting integration.
