+### Minor Changes
+
+- 560d8af: Add a unified tag visualization: the `Tag` atom plus `TagCanvas` and
+  `TagTreeEditor`. It renders walkerOS data-elb tagging as nested rectangles
+  (entity, context, global, action, property) with an auto-laid-out reading view
+  and an overlay you can draw onto a screenshot. The overlay editor supports
+  dragging and resizing rectangles, keeping every tag fully nested or fully
+  separate. The existing `TagSkeleton` and `TagSkeletonOverlay` continue to
+  work.
+
+### Patch Changes
+
+- 2d64ed2: CodeBox now memoizes its toolbar and tabs so a validation-marker
+  update repaints only the error and warning badges instead of re-rendering the
+  whole editor. This removes the visible editor flicker when content or markers
+  change rapidly.
+- 560d8af: The built bundle now preserves its leading `"use client"` directive,
+  so Next.js treats the package as a client boundary. The minifier could
+  previously strip it, which broke server components that import the package at
+  build time.

 # @walkeros/cli
 
+## 4.2.0
+
+### Minor Changes
+
+- 654ba38: `walkeros run` now accepts a `.tar.gz`/`.tgz` flow archive (URL or
+  local file): it extracts the bundle and its `node_modules/` and runs it, so
+  server flows with external step packages resolve them at runtime.
+  `walkeros bundle -o flow.tar.gz` packs a server bundle directory into that
+  archive. Web single-file bundles do not support archive output.
+- 6a72a32: The MCP `flow_simulate` and `flow_bundle` tools now accept a cloud
+  flow id as `configPath`, so you can simulate or bundle a saved flow without a
+  manual file round-trip, and repeated simulations reuse a prebuilt bundle for
+  faster runs. Loading or fetching a flow with no default project set now
+  returns a clear "no default project" error, and `flow_examples` surfaces a
+  referenced package's shipped examples when a step has none inline. Bundle
+  stats now report the real total bundle size and list package names instead of
+  a per-package estimate, and the GA4 transformer documents its wiring contract
+  via package hints.
+- 9d066cc: Preview creation can now target a deployed version: pass
+  `source: { kind: 'deployment-version', deploymentVersionId }` to
+  `createPreview` (CLI) or the MCP `flow_manage` `preview_create` action to
+  preview what's live instead of the flow's draft. Deleting a preview no longer
+  errors on the empty `204 No Content` response and resolves to a confirmation
+  record.
+- 654ba38: Trace telemetry now activates at runtime by polling the deployment's
+  trace window, so web and server flows start and stop full-payload recording
+  without a redeploy. A future trace window upgrades a flow to full inbound and
+  outbound recording, and a null or past window reverts to the flow's `observe`
+  baseline and self-expires.
+- e8f6909: Add a `secret_manage` MCP tool (and matching CLI functions) to manage
+  a flow's secrets. List secret metadata, create, rotate, and delete secrets
+  that flow steps reference as `$env.<NAME>`. Values are write-only: encrypted
+  at rest and never returned or logged.
+- 6a72a32: Source simulation gains a `collector` step that runs the real
+  collector enrichment and returns the fully enriched event. Transformer
+  simulation now accepts an optional raw `ingest` so request decoders like GA4
+  can be tested standalone by supplying a `url`. The `flow_simulate` MCP tool
+  accepts the new collector step and the transformer `ingest` input.
+
+### Patch Changes
+
+- e8f6909: The bundled API contract (`spec.json` and the generated
+  `api.gen.d.ts`) now covers the full served surface, adding typed paths for
+  service accounts, invitations, billing, deployments and their sub-resources,
+  custom domains, entitlements, LLM settings, chat sessions, MCP tokens,
+  runners, and the package catalog. No runtime behavior change; clients gain
+  accurate types for these endpoints.
+- 5b1a134: Browser flow bundles are now emitted as an IIFE so all internal code
+  stays inside a private scope. Previously the bundled helper functions could
+  leak onto the global `window` object and collide with other scripts on the
+  page, such as Google Analytics or a consent manager. Server bundles are
+  unchanged and still emit ESM.
+- b98474f: Source-level mapping examples for the dataLayer source now key on the
+  prefix as entity and the gtag action as action: `mapping.<prefix>.<action>`.
+  The shipped `examples/mapping.ts`, the comprehensive `flow-complete.json`
+  example, and the related docs reflect the convention, including the
+  special-cased actions `consent`, `config`, and `set` whose trailing token is
+  dropped by the entity/action split.
+- 59aa9e1: Refresh runtime dependencies to their latest majors: Express 5,
+  Commander 15, better-sqlite3 12, @libsql/client 0.17, Google Cloud
+  functions-framework 5, mixpanel 0.22, and jsdom 29. No public API changes;
+  installs now pull the current versions of these SDKs.
+- e8f6909: Documentation fix: server source `config.ingest` examples now use the
+  `map` operator with direct request field paths instead of a bare object. A
+  bare object like `{ url: 'req.url' }` is silently inert, so the ingest stayed
+  empty and downstream `ingest.*` fields never resolved. Affects package hints,
+  READMEs, the core source type docs, and the bundled CLI example.
+- d39a6a1: Bundle skeletons now expose each package's dev exports through a lazy
+  loader. Production deploy bundles drop it entirely, so a shipped `walker.js`
+  never carries the dev schema graph, while in-process simulate and push inline
+  the dev exports so they resolve on a minimal runtime without the source
+  packages installed alongside. This fixes a browser deploy bundle that could
+  fail to build or retain dev schemas, and web simulation that could not find
+  the dev exports.
+- 9d066cc: The MCP now loads flows by ID, requires the `flow_simulate` `step`
+  parameter it always enforced, and adds a `diagnostics` tool reporting client
+  and CLI versions plus backend reachability. Package discovery returns a
+  complete catalog with a warning when a source degrades, instead of silently
+  caching partial results, and returned flow configs are round-trip safe
+  (structural values stay literal). The demo source can now be simulated as a
+  source step; the CLI also exports `VERSION` and `resolveAppUrl` and clears a
+  deleted default project.
+- e2a60ae: The wrapped browser bundle can now install a telemetry observer
+  without a trace poll. When the telemetry options omit `traceUrl`, the bundle
+  emits at a fixed level with no polling, suited to short-lived, URL-opted-in
+  sessions. Bundles that pass `traceUrl` keep the existing poll behavior.
+- 23d4b86: New `@walkeros/transformer-validate` transformer validates events
+  against JSON Schema contracts. It runs in both web and server flows, supports
+  strict and pass modes, and writes the verdict and error list to configurable
+  paths so you can gate or observe event quality.
+
+  The declarative per-step `validate` field on sources, transformers, and
+  destinations is removed. Define event shapes in the top-level `contract` and
+  enforce them at runtime by adding a `transformer-validate` step that
+  references them via `$contract.<name>`; `format: true` still checks an event
+  is a valid `WalkerOS.PartialEvent`. Design-time validation now checks step
+  examples against the resolved contract.

 # @walkeros/collector
 
+## 4.2.0
+
+### Minor Changes
+
+- 654ba38: Consent and state-gated source reactions, such as the session
+  source's session start, now fire reliably regardless of source init order or
+  whether state arrives before or after `run`. The collector delivers each state
+  change exactly once per subscriber, so sources no longer need to re-fire on
+  repeat collector notifications of the same state.
+- c27d3c1: Destinations now batch every event when you set `config.batch`, with
+  no `'* *'` wildcard mapping rule needed. A bare number sets the debounce wait;
+  `{ wait, size, age }` tunes the window. Rule-level `batch` still overrides per
+  event type, and pending batches now flush on shutdown.
+
+  Migration: if you previously set `config.batch` alongside a single
+  non-wildcard rule `batch`, `config.batch` only capped that rule before; it now
+  batches all of the destination's events. To batch only specific events, drop
+  `config.batch` and set `batch` on those rules.
+
+- 126c0f1: A source or destination with a `require` gate now activates reliably
+  from the collector's current recorded state, regardless of source init order
+  or which source provided the required state (such as a CMP applying consent).
+  CMP and session sources now perform their initial consent read during
+  `init()`, so construction stays side-effect free.
+
+### Patch Changes
+
+- 76d32c1: Batched destination delivery now reports failures. A batch push that
+  fails (including BigQuery row errors) is routed to the dead-letter buffer and
+  counted as failed instead of being silently dropped, and graceful shutdown
+  waits for in-flight batches to finish. Also fixes a shutdown timer that could
+  delay process exit, and makes a zero millisecond batch wait (`batch: 0`)
+  correctly enable batching.
+- 5b1a134: Lifecycle dispatch now fails closed when called with a non-collector
+  argument. If an internal function is ever reached by foreign code (for example
+  a global name collision), it returns quietly instead of throwing, so it can no
+  longer break the surrounding page.
+- 908d6f0: Promote chain, route shape, and reference scanner helpers to the
+  public surface so app and tooling can resolve transformer chains, probe route
+  shapes, and discover `$flow.` references without reaching into internal
+  modules:
+  - collector: re-export `walkChain` (resolve a transformer chain start into the
+    ordered step IDs) and `extractTransformerNextMap` (read static next-links
+    from a `Transformer.Transformers` map).
+  - core: re-export `isRouteArray` and `isRouteConfigEntry` (the canonical shape
+    probes for `Transformer.Route`) and add `scanFlowRefs(value, into?)`, which
+    walks any value (string, object, array) and returns every `$flow.<name>`
+    reference found, including refs nested inside `$code:` snippets.
+
+- 6a72a32: Source simulation gains a `collector` step that runs the real
+  collector enrichment and returns the fully enriched event. Transformer
+  simulation now accepts an optional raw `ingest` so request decoders like GA4
+  can be tested standalone by supplying a `url`. The `flow_simulate` MCP tool
+  accepts the new collector step and the transformer `ingest` input.
+- 3eb2467: Add a declarative `state` block for `get`/`set` against a store,
+  replacing `$code:` for simple fetch and stash. Available on source,
+  transformer, and destination steps; defaults to an in-memory store.
+- 5b1a134: Stores now use one structured value type with binary (`Uint8Array`)
+  as a first-class leaf, serialized by a shared codec. A new `file: true` store
+  option serves byte-exact assets such as walker.js (default is structured
+  key-value). TTL is owned by the cache layer, not the store. Sheets is
+  structured-only and rejects `file: true`.

 # @walkeros/core
 
+## 4.2.0
+
+### Minor Changes
+
+- e8f6909: Add an optional, strictly-typed `config.credentials` field to

+  under `config.credentials`, validated per package and resolved from `$env`.
+  The package-specific `settings.credentials` still works but is deprecated, so

+  (e.g. `settings.bigquery`) is unchanged.

+  without a redeploy. A future trace window upgrades a flow to full inbound and

+  accepts the new collector step and the transformer `ingest` input.
+- 23d4b86: New `@walkeros/transformer-validate` transformer validates events
+  against JSON Schema contracts. It runs in both web and server flows, supports
+  strict and pass modes, and writes the verdict and error list to configurable
+  paths so you can gate or observe event quality.
+
+  The declarative per-step `validate` field on sources, transformers, and
+  destinations is removed. Define event shapes in the top-level `contract` and
+  enforce them at runtime by adding a `transformer-validate` step that
+  references them via `$contract.<name>`; `format: true` still checks an event
+  is a valid `WalkerOS.PartialEvent`. Design-time validation now checks step
+  examples against the resolved contract.
+
+### Patch Changes
+
+- 76d32c1: Batched destination delivery now reports failures. A batch push that
+  fails (including BigQuery row errors) is routed to the dead-letter buffer and
+  counted as failed instead of being silently dropped, and graceful shutdown
+  waits for in-flight batches to finish. Also fixes a shutdown timer that could
+  delay process exit, and makes a zero millisecond batch wait (`batch: 0`)
+  correctly enable batching.
+- 908d6f0: Promote chain, route shape, and reference scanner helpers to the
+  public surface so app and tooling can resolve transformer chains, probe route
+  shapes, and discover `$flow.` references without reaching into internal
+  modules:
+  - collector: re-export `walkChain` (resolve a transformer chain start into the
+    ordered step IDs) and `extractTransformerNextMap` (read static next-links
+    from a `Transformer.Transformers` map).
+  - core: re-export `isRouteArray` and `isRouteConfigEntry` (the canonical shape
+    probes for `Transformer.Route`) and add `scanFlowRefs(value, into?)`, which
+    walks any value (string, object, array) and returns every `$flow.<name>`
+    reference found, including refs nested inside `$code:` snippets.
+
+- f4a9013: Fix `$flow` reference scanning to match the resolver's name grammar,
+  so names with leading digits or hyphens no longer produce false-positive
+  references.
+- d65bbde: `FlowState` records can now carry an optional `platform` field
+  (`'web' | 'server'`) identifying the runtime that produced the state.
+  Observers can use it alongside `flowId` to correlate telemetry across web and
+  server runtimes of the same flow.
+- e8f6909: Documentation fix: server source `config.ingest` examples now use the
+  `map` operator with direct request field paths instead of a bare object. A
+  bare object like `{ url: 'req.url' }` is silently inert, so the ingest stayed
+  empty and downstream `ingest.*` fields never resolved. Affects package hints,
+  READMEs, the core source type docs, and the bundled CLI example.
+- c27d3c1: Request caching now persists structured HTTP responses, including
+  binary bodies (`Buffer`, `Uint8Array`, `ArrayBuffer`), to byte/string store
+  backends (filesystem, S3, GCS, in-memory) and honors TTL. Previously, caching
+  a response could crash the process or never populate, and entries never
+  expired. Cached values now round-trip safely (binary bodies decode back as a
+  `Buffer`) and expire correctly instead of serving stale content after a
+  redeploy.
+- 3eb2467: Add a declarative `state` block for `get`/`set` against a store,
+  replacing `$code:` for simple fetch and stash. Available on source,
+  transformer, and destination steps; defaults to an in-memory store.
+- 5b1a134: Stores now use one structured value type with binary (`Uint8Array`)
+  as a first-class leaf, serialized by a shared codec. A new `file: true` store
+  option serves byte-exact assets such as walker.js (default is structured
+  key-value). TTL is owned by the cache layer, not the store. Sheets is
+  structured-only and rejects `file: true`.
+- 18c9469: Flow validation now scopes the "web flows cannot reference a managed
+  secret" check per flow. A multi-flow config where a web flow forwards to a
+  server flow that holds a `$secret.` reference now validates cleanly, instead
+  of the server flow's secret being wrongly flagged against the web flow.

 # @walkeros/mcp
 
+## 4.2.0
+
+### Minor Changes
+
+- 9d066cc: The MCP now loads flows by ID, requires the `flow_simulate` `step`
+  parameter it always enforced, and adds a `diagnostics` tool reporting client
+  and CLI versions plus backend reachability. Package discovery returns a
+  complete catalog with a warning when a source degrades, instead of silently
+  caching partial results, and returned flow configs are round-trip safe
+  (structural values stay literal). The demo source can now be simulated as a
+  source step; the CLI also exports `VERSION` and `resolveAppUrl` and clears a
+  deleted default project.
+- 6a72a32: The MCP `flow_simulate` and `flow_bundle` tools now accept a cloud
+  flow id as `configPath`, so you can simulate or bundle a saved flow without a
+  manual file round-trip, and repeated simulations reuse a prebuilt bundle for
+  faster runs. Loading or fetching a flow with no default project set now
+  returns a clear "no default project" error, and `flow_examples` surfaces a
+  referenced package's shipped examples when a step has none inline. Bundle
+  stats now report the real total bundle size and list package names instead of
+  a per-package estimate, and the GA4 transformer documents its wiring contract
+  via package hints.
+- 9d066cc: Preview creation can now target a deployed version: pass
+  `source: { kind: 'deployment-version', deploymentVersionId }` to
+  `createPreview` (CLI) or the MCP `flow_manage` `preview_create` action to
+  preview what's live instead of the flow's draft. Deleting a preview no longer
+  errors on the empty `204 No Content` response and resolves to a confirmation
+  record.
+- e8f6909: Add a `secret_manage` MCP tool (and matching CLI functions) to manage
+  a flow's secrets. List secret metadata, create, rotate, and delete secrets
+  that flow steps reference as `$env.<NAME>`. Values are write-only: encrypted
+  at rest and never returned or logged.
+
+### Patch Changes
+
+- 6a72a32: Source simulation gains a `collector` step that runs the real
+  collector enrichment and returns the fully enriched event. Transformer
+  simulation now accepts an optional raw `ingest` so request decoders like GA4
+  can be tested standalone by supplying a `url`. The `flow_simulate` MCP tool
+  accepts the new collector step and the transformer `ingest` input.

 # @walkeros/mcp-source-browser
 
+## 4.2.0
+
+### Minor Changes
+
+- 21ac669: Add the `data-elb_` scoped generic attribute. It carries the same
+  `key:value` properties as the blanket `data-elb-` generic, but only events
+  whose triggered element is nested below the `data-elb_` element receive them.
+  The `createTagger()` API gains a `scoped()` method and the `generate_tagging`
+  MCP tool gains a `scoped` input to produce it. Use `data-elb-` for properties
+  every trigger in an entity should carry, and `data-elb_` when only triggers
+  within a specific branch should.
+
+### Patch Changes
+
+- 59aa9e1: Refresh runtime dependencies to their latest majors: Express 5,
+  Commander 15, better-sqlite3 12, @libsql/client 0.17, Google Cloud
+  functions-framework 5, mixpanel 0.22, and jsdom 29. No public API changes;
+  installs now pull the current versions of these SDKs.

+
+- 2d64ed2: `getHashServer` now accepts an `algorithm` option (`sha256` default,
+  or `md5`), so destinations can request either digest from the shared util
+  instead of calling Node crypto directly. Criteo's email hashing composes this
+  util for its md5, sha256, and sha256_md5 forms. No behavior change for
+  existing SHA-256 callers.

 # @walkeros/server-destination-criteo
 
+## 4.2.0
+
+### Patch Changes
+
+- 2d64ed2: `getHashServer` now accepts an `algorithm` option (`sha256` default,
+  or `md5`), so destinations can request either digest from the shared util
+  instead of calling Node crypto directly. Criteo's email hashing composes this
+  util for its md5, sha256, and sha256_md5 forms. No behavior change for
+  existing SHA-256 callers.

+  under `config.credentials`, validated per package and resolved from `$env`.

+  (e.g. `settings.bigquery`) is unchanged.
+
+### Patch Changes
+
+- 76d32c1: Batched destination delivery now reports failures. A batch push that
+  fails (including BigQuery row errors) is routed to the dead-letter buffer and
+  counted as failed instead of being silently dropped, and graceful shutdown
+  waits for in-flight batches to finish. Also fixes a shutdown timer that could
+  delay process exit, and makes a zero millisecond batch wait (`batch: 0`)
+  correctly enable batching.
+- db97edc: The BigQuery destination now creates the `timing` column as `FLOAT64`
+  instead of `INT64`. Event timing carries sub-second decimal precision, which
+  was previously truncated to whole numbers on write. Existing tables keep their
+  column type; alter it to `FLOAT64` to preserve precision going forward.

 # @walkeros/server-source-gcp
 
+## 4.2.0
+
+### Minor Changes
+
+- e8f6909: Add an optional, strictly-typed `config.credentials` field to
+  destinations, stores, and sources. Service-account credentials now configure
+  under `config.credentials`, validated per package and resolved from `$env`.
+  The package-specific `settings.credentials` still works but is deprecated, so
+  move credentials to `config.credentials`. The raw `settings.<sdk>` passthrough
+  (e.g. `settings.bigquery`) is unchanged.
+
+### Patch Changes
+
+- 59aa9e1: Refresh runtime dependencies to their latest majors: Express 5,
+  Commander 15, better-sqlite3 12, @libsql/client 0.17, Google Cloud
+  functions-framework 5, mixpanel 0.22, and jsdom 29. No public API changes;
+  installs now pull the current versions of these SDKs.

 # @walkeros/server-store-fs
 
+## 4.2.0
+
+### Patch Changes
+
+- c27d3c1: Request caching now persists structured HTTP responses, including
+  binary bodies (`Buffer`, `Uint8Array`, `ArrayBuffer`), to byte/string store
+  backends (filesystem, S3, GCS, in-memory) and honors TTL. Previously, caching
+  a response could crash the process or never populate, and entries never
+  expired. Cached values now round-trip safely (binary bodies decode back as a
+  `Buffer`) and expire correctly instead of serving stale content after a
+  redeploy.
+- 5b1a134: Stores now use one structured value type with binary (`Uint8Array`)
+  as a first-class leaf, serialized by a shared codec. A new `file: true` store
+  option serves byte-exact assets such as walker.js (default is structured
+  key-value). TTL is owned by the cache layer, not the store. Sheets is
+  structured-only and rejects `file: true`.

+- 6a72a32: The MCP `flow_simulate` and `flow_bundle` tools now accept a cloud

+  manual file round-trip, and repeated simulations reuse a prebuilt bundle for
+  faster runs. Loading or fetching a flow with no default project set now
+  returns a clear "no default project" error, and `flow_examples` surfaces a
+  referenced package's shipped examples when a step has none inline. Bundle
+  stats now report the real total bundle size and list package names instead of
+  a per-package estimate, and the GA4 transformer documents its wiring contract
+  via package hints.

+# @walkeros/transformer-validate
+
+## 4.2.0
+
+### Minor Changes
+
+- 23d4b86: New `@walkeros/transformer-validate` transformer validates events
+  against JSON Schema contracts. It runs in both web and server flows, supports
+  strict and pass modes, and writes the verdict and error list to configurable
+  paths so you can gate or observe event quality.
+
+  The declarative per-step `validate` field on sources, transformers, and
+  destinations is removed. Define event shapes in the top-level `contract` and
+  enforce them at runtime by adding a `transformer-validate` step that
+  references them via `$contract.<name>`; `format: true` still checks an event
+  is a valid `WalkerOS.PartialEvent`. Design-time validation now checks step
+  examples against the resolved contract.
+
+### Patch Changes
+
+- 0cad016: Fix schema-only contract rules being skipped during validation. A
+  contract rule that carries only a whole-event `schema` (no `events` block) is
+  now enforced instead of being treated as an inert inline schema.

 # @walkeros/web-core
 
+## 4.2.0
+
+### Minor Changes
+
+- d65bbde: `getEnv` is now generic over a destination's `Env`. Passing your env
+  type (`getEnv<Env>(env)`) returns `window`/`document` as the real DOM globals
+  merged with your declared SDK shape, so destinations no longer need to cast
+  browser globals (`as Window`/`as Document`) at the call site.

+
+Send walkerOS events to Piano Analytics.
+
+[Documentation](https://www.walkeros.io/docs/destinations/web/piano) &bull;
+[NPM Package](https://www.npmjs.com/package/@walkeros/web-destination-piano)
+&bull;
+[Source Code](https://github.com/elbwalker/walkerOS/tree/main/packages/web/destinations/piano)
+
+This destination forwards collector-processed events to the official
+[Piano Analytics JavaScript SDK](https://github.com/at-internet/piano-analytics-js)
+(`pa`) via `pa.sendEvent`.
+
+## Installation
+
+```bash
+npm install @walkeros/web-destination-piano
+```
+
+## Quick start
+
+```json
+{
+  "version": 4,
+  "flows": {
+    "default": {
+      "config": {
+        "platform": "web"
+      },
+      "destinations": {
+        "piano": {
+          "package": "@walkeros/web-destination-piano",
+          "config": {
+            "loadScript": true,
+            "settings": {
+              "site": 123456789,
+              "collectDomain": "https://example.pa-cd.com"
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+With `loadScript: true` the destination loads the Piano SDK script and calls
+`pa.setConfigurations({ site, collectDomain })` on init. If you load the SDK
+yourself, omit `loadScript` and make sure `pa` is available on `window`.
+
+## Settings
+
+| Setting         | Type     | Required | Description                                                  |
+| --------------- | -------- | -------- | ------------------------------------------------------------ |
+| `site`          | `number` | yes      | Piano Analytics site id, from your collection settings.      |
+| `collectDomain` | `string` | yes      | Collection domain endpoint, like `https://xxxxxxx.pa-cd.com` |
+| `options`       | `object` | no       | Additional Piano `setConfigurations` options merged on init. |
+
+## Mapping
+
+Each event is mapped to a Piano event name and a property object, then sent with
+`pa.sendEvent(name, data)`. Piano uses dot-notation event names like
+`page.display`.
+
+| walkerOS event   | Piano event                | Notes                       |
+| ---------------- | -------------------------- | --------------------------- |
+| `page view`      | `page.display`             | Page name and chapter.      |
+| `order complete` | `transaction.confirmation` | Transaction id and revenue. |
+
+```json
+{
+  "mapping": {
+    "page": {
+      "view": {
+        "name": "page.display",
+        "data": { "map": { "page": "data.title" } }
+      }
+    }
+  }
+}
+```
+

 # @walkeros/web-source-browser
 
+## 4.2.0
+
+### Minor Changes
+
+- 21ac669: Add the `data-elb_` scoped generic attribute. It carries the same
+  `key:value` properties as the blanket `data-elb-` generic, but only events
+  whose triggered element is nested below the `data-elb_` element receive them.
+  The `createTagger()` API gains a `scoped()` method and the `generate_tagging`
+  MCP tool gains a `scoped` input to produce it. Use `data-elb-` for properties
+  every trigger in an entity should carry, and `data-elb_` when only triggers
+  within a specific branch should.
+
+### Patch Changes
+
+- 5b1a134: The single-instance guard is now scoped to the window instead of the
+  module, so loading the tag more than once on the same page is inert rather
+  than re-initializing. A second load no longer re-binds DOM triggers, re-adopts
+  the event layer, or surfaces an error to the host page.
+- 776e5f9: Step examples are no longer bundled into production output. They were
+  accidentally exported from the production entry of these packages and pulled
+  into bundled JS. Examples remain available via the package `./dev` subpath for
+  simulation and testing.

 # @walkeros/web-source-datalayer

+
+### Patch Changes
+
+- b98474f: Source-level mapping examples for the dataLayer source now key on the
+  prefix as entity and the gtag action as action: `mapping.<prefix>.<action>`.
+  The shipped `examples/mapping.ts`, the comprehensive `flow-complete.json`
+  example, and the related docs reflect the convention, including the
+  special-cased actions `consent`, `config`, and `set` whose trailing token is
+  dropped by the entity/action split.
+- 776e5f9: Step examples are no longer bundled into production output. They were
+  accidentally exported from the production entry of these packages and pulled
+  into bundled JS. Examples remain available via the package `./dev` subpath for
+  simulation and testing.

 # @walkeros/source-demo
 
+## 4.2.0
+
+### Patch Changes
+
+- 9d066cc: The MCP now loads flows by ID, requires the `flow_simulate` `step`
+  parameter it always enforced, and adds a `diagnostics` tool reporting client
+  and CLI versions plus backend reachability. Package discovery returns a
+  complete catalog with a warning when a source degrades, instead of silently
+  caching partial results, and returned flow configs are round-trip safe
+  (structural values stay literal). The demo source can now be simulated as a
+  source step; the CLI also exports `VERSION` and `resolveAppUrl` and clears a
+  deleted default project.
+- 776e5f9: Step examples are no longer bundled into production output. They were
+  accidentally exported from the production entry of these packages and pulled
+  into bundled JS. Examples remain available via the package `./dev` subpath for
+  simulation and testing.
