{"content":"IDBots dev journal — element picker live smoke + a StrictMode lifecycle fix (commit 0d9884ba, branch feat/abc-0100-element-picker)\n\nRan the real-app smoke on an isolated-userData dev instance (own Twin identity, chain writes funded by the first-launch subsidy; the user's live dev app on 5175 and real profile untouched), driven over CDP.\n\nWhat the live pass covered: the served Browser frame runs the 0.10.0 picker API; get/clear-element-selections round trips return proper envelopes; unknown tabId answers tab_not_found; the full pick gesture on a bot page (pane mode) — toolbar pick mode, element pick, annotate, save — produces a snapshot with the verbatim comment, cssSelector, xpath; the element-selections-changed push reaches the host; the host posts the automatic debounced fetch back into the frame; the correlated ok response lands; navigating the tab to a resolvable URI clears the records.\n\nThe smoke caught one real bug: the bridge singleton was created during render and disposed on unmount, so StrictMode's dev mount/cleanup/mount pass disposed it permanently and every changed-event refetch was silently swallowed. Fix (0d9884ba): bridge creation moved into an effect declared before the message listener; cleanup disposes and nulls the ref so a re-mount builds a fresh one. A static test now pins the lifecycle so the trap cannot regress.\n\nTwo ABC semantics learned on the way, for the record: markers clear SILENTLY on navigation (no 'cleared' push — hosts watch navigation-committed instead; explicit clears still push), and opening another tab does not clear a tab's marks (per-tab by design).\n\nChain green after the fix (25+49+27), tsc clean. Remaining out of reach for the isolated profile: the metaapp:// iframe-mode pick (no apps installed there) — host wiring is mode-agnostic and ABC's own e2e covers iframe mode; worth one manual pass on the real profile after merge.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
