 # Changelog
 
-## 0.26.0
-
-Sample flows follow the hub's wire flag (sealed-areas rework):
-
-- **`FlowEditorPage.sampleFlowNames`** — the host passes the set of
-  flow names the hub reports as bundled samples
-  (`FlowSummary.sample`). This is now the ONLY source of the
-  "Example" chip; the editor's own content-marker scan is gone (it
-  had silently drifted from the hub's renamed sample header and
-  missed every current sample). Null = no host info = no chips.
-- **Examples group.** Sample flows collapse under one
-  "Examples (N)" row below the operator's own flows, expanded on
-  demand — or by default when there is nothing else to show.
-- **`FlowEditorPage.onImportSamples`** — optional empty-list action
-  ("Import example flows"); sealed areas start without samples, so
-  hosts wire this as the deliberate pull. The list refreshes itself
-  after the import.
-- `FaiEmptyState` gained an optional `action` slot.
-- The editor reloads its file list when the host changes `flowsDir`
-  or delivers the sample set after an async fetch.
-
-## 0.25.0
-
-Honest install badge — the flow list and analyzer only offer
-"Install" for capabilities a configured store can actually resolve:
-
-- **Store-resolvability split in the flow list.** Missing
-  capabilities are classified BEFORE any click: store-resolvable
-  ones keep the amber chip + Install link (which now installs only
-  those), the rest render a quiet "not in store" chip whose tooltip
-  explains the three recovery paths (local install via
-  `chain install --link`, adding the providing store, configuring
-  the MCP/n8n integration). Previously the Install action covered
-  every missing capability and could end in the hub's
-  "no store entry for '<name>'" error.
-- New host contract: `_FileList` consumes the host's
-  `storeCapabilities` (already exposed on `FlowEditorPage`) for the
-  split; hosts should pass only capabilities the store can install
-  (installable status, native kind).
-- **Analyzer not-in-store message** now names all three recovery
-  paths instead of only the local-install hint (EN + DE).
-
-Project separation in the flow list:
-
-- **Workspace filter.** The file list filters by the host's
-  `activeProject`; flows without a `project:` key count as
-  `general` (display semantics — the file stays the truth and is
-  never rewritten). A project with no flows gets its own honest
-  empty state naming the project and the way out.
-- **New flows are stamped** with the active project's `project:`
-  key (`general` and "all projects" stay unstamped — no key
-  already means general).
-- **`toolbarTrailing` slot** on `FlowEditorPage`: the host can
-  place its workspace switcher in the editor's single toolbar.
-- **`flowsDir` injection** on `FlowEditorPage`: tests (and other
-  hosts) point the editor at any directory instead of the
-  hard-wired `~/.chain/data/flows` — the new widget tests run
-  against a temp dir, never the operator's flows.
-
-Disturbance hardening:
-
-- **Unknown ≠ absent.** `storeCapabilities` is nullable now
-  (null = store state unknown): missing capabilities then render
-  the plain missing chip with an honest tooltip — no install
-  offer, no "not in store" claim — and the analyzer message says
-  the store cannot be checked right now (EN + DE). Previously an
-  unreachable store made every missing capability claim
-  "not in store".
-
-## 0.24.1
-
-- No ALL-CAPS "FLOWS" panel header: the page toolbar already names
-  the page — the duplicate label read as a broken title hierarchy.
-  The refresh action moved next to the list filter.
-- Doc comments name the current CLI (`chain install`).
-
-## 0.24.0
-
-Usertest-panel fixes (flow list + language):
-
-- **Builtin-capability truth from the hub.** Removed the hardcoded
-  client-side builtin set (`{'debug.echo'}`): missing-module
-  detection now trusts the host-supplied capability list alone,
-  which already includes the hub's real builtins. Fixes the bundled
-  `hello` flow showing a play button on hubs that don't have
-  `debug.echo` installed.
-- **Missing-modules badge redesigned.** Status ("N Module fehlen",
-  quiet neutral chip with an amber dot) and the install action
-  (own link, never truncated) are separate elements; the former
-  combined orange chip read as an error wall and ellipsized the
-  action word.
-- **Flow-list filter.** Case-insensitive substring filter above the
-  list, with an honest "no flow matches" empty state.
-- **Formal address (Sie) in all German strings** plus missing
-  commas/quotes in the empty-state sentences.
-- Analyzer hint now names the current CLI (`chain install --link`,
-  was `fai install --link`).
-
 ## 0.23.0
 
 - Run tab file inputs accept a host-injected native file picker
