Pup - Puppeteer Bridge

Birth-time handle resolution: each new window is born at a unique off-screen position and its OS handle captured while off-screen and small (before park maximizes it), the only unambiguous moment for a same-profile window; the resolver trusts this birth handle ahead of all geometry heuristics. Finally resolves multi-window profiles the width-wiggle never could

Reliable wiggle-free handle resolution: a profile process with exactly one window resolves to that window directly (works on maximized windows, which the width-wiggle never could); multi-window profiles still leave bare rather than guess until birth-time resolution lands

Make window-handle resolution conservative (correct-or-bare, never wrong): raise the wiggle serialization timeout above the enumeration time so concurrent wiggles cannot collapse multiple windows onto one handle; use a distinctive narrow marker width real windows never sit at; verify the width actually applied; require EXACTLY ONE match or leave the window bare rather than paint a guessed/shared handle

Kill overlay drift at the source: one centralized debounced overlay re-sync now fires for every mutating verb (navigate/reload/back/forward/switch_tab/click/type/eval) plus close_tab/close_window, clearing the favicon cache and repainting via the ungated applyAppOverlay (refreshWindowChrome was a no-op under minimalTouch), without touching the cached handle so no routine verb triggers the wiggle

Fix window-handle desync + stuck regenerate: time-box the width-wiggle lock so a hung holder cannot deadlock the whole chain (was leaving every window hwnd=None); persist the resolved OS handle to the session file and restore+validate it on respawn so windows stop re-wiggling after every ship; regenerate button preempts a wedged busy flag, per-window timeouts, and always clears the flag

Regenerate-overlays button now runs the sweep in the background and answers instantly (dashboard icons update live via SSE); header shows regenerating/last-sweep status; per-window drift report logged

Dashboard taskbar strip now shows the teal pup tile for every pup window (matching the real taskbar) instead of Chrome's exe logo for un-stamped windows; add a Regenerate All Overlay Icons header button that re-runs the from-scratch overlay algorithm on every window and reports which windows drifted

Fix missing taskbar overlay: hwndBelongsToPup now requires a real top-level visible Chrome_WidgetWin_1 frame, not just any window owned by the profile process. A stale same-process utility handle (18) was passing the pid-only check forever, so overlays painted onto a non-taskbar window and never appeared

Fix duplicate tab on burst opens: the popup-tracker was double-attaching pup's own in-window window.open blanks (which addTabToSession already adopts); it now skips any tab tagged with the pupclaim_ window.name marker

Fix in-window tab adoption: identify the window.open tab by a unique per-call window.name marker instead of set-difference, which under a burst of adds could adopt the wrong new target and duplicate tabs

Fix orphaned about:blank tabs: adopt the window.open tab by target set-difference instead of a racy opener match, which used to leave a stray blank tab beside the real one whenever the anchor page was mid-navigation

Serialize the width-wiggle resolution so it is actually unique (1.9.290 collapsed everything onto one hwnd because the enforcer fires resolves CONCURRENTLY - their width changes and window enumerations overlapped, so every session matched whichever window was momentarily at a marker width). A global lock now guarantees exactly one wiggle (set unique width -> enumerate -> restore) runs at a time, with the lock released on every path including the error path (hoisted release handle so the outer catch frees it - no deadlock).

Robust observer-proof window resolution via UNIQUE-WIDTH WIGGLE (finally kills the dup-hwnd bug for all windows, clean titles kept). With titleTag off, the transient-title approach was fought by each page's own title observer (un-disconnectable on pre-1.9.288 pages), so same-profile windows parked at the identical rect collapsed onto one hwnd. New approach: when the tag is off, pup gives the window being resolved a UNIQUE width via CDP Browser.setWindowBounds (pup controls this directly, no page script can fight it), matches the one OS window at that exact width, then restores - deterministic and unambiguous even for many same-profile windows. Guarded to never resize a foreground window the user is looking at (falls back to plain bounds there); the window is off-screen during most resolves so the width change is invisible. Title-tag-ON path still uses the exact persistent-tag find. Together with the reconciler's duplicate-hwnd self-heal (clears any shared cache to force re-resolve), every window binds to its own unique handle.

Duplicate-hwnd self-heal: the reconciler now detects any OS handle claimed by more than one live session and clears the cached hwnd on all of them, forcing each to re-resolve to its own unique window (reliable now that 1.9.288 stopped the tag-strip observer from fighting the transient resolution). This corrects stale wrong-hwnd caches that per-profile validation cannot catch (two windows of the same Chrome process), so John's wildlife-compare/haircut-review shared-handle case self-heals within a sweep instead of persisting. Verified: two fresh same-profile windows resolve to distinct handles.
