"Reconnecting…" indicator during the #115 reconnect-via-resume grace window

Background

Follow-up surfaced during #115 (reconnect-via-resume, PR #138) review. Filed per substrate-for-decision discipline so the evidence stays attached while fresh — this is a tracker, not a build commitment; operator/Bosun prioritize (close as wontfix if not wanted).

The gap #115 opens

#93 (Option A) armed the "connection lost" overlay immediately on an accidental drop. #115 now attempts a seamless reconnect first, holding the last playing frame for up to RECONNECT_GRACE_MS (8s) before either:

succeeding → board re-syncs, no interruption (a clear win over #93), or
failing → the #93 overlay arms, then backToYard().

On the failure path, that's an up-to-8s frozen frame with no feedback that #93 didn't have. Surveyor's #138 review framed it precisely: an indicator fills a gap this PR opens, not gold-plating. Both Surveyor and I lean yes.

Proposed fix-shape (Shipwright lane, ~size S)

A small net.ts → main signal on reconnect attempt-start and recovered/failed (net-new callback surface — #138 deliberately kept reconnect transparent to main, so this adds the hook). Options: extend onClose semantics, or a dedicated onReconnect(phase) callback.
A "RECONNECTING…" overlay reusing the disconnectOverlayUntil rendering machinery (render.ts), cleared on success or replaced by the existing connection-lost overlay on failure.
A navState.reconnecting field for harness observability (mirrors connectionLost).
Unblocks growing the client budget toward the server's full 25s — once the wait is legible, the 8s cap (chosen to bound the invisible freeze) can grow, maximizing reconnect success. See PR #138's "Why X, when Y instead" rationale.

Verification expectation

WS-mock (the #92 substrate, extended in #138 for multi-connection): assert the reconnecting overlay arms on drop-with-token and clears on the resume matchStart; mutation-prove each.

#139 reconnecting-overlay UX — Herald (creative-head)

This is the missing UX-surface for the existing #12 reconnect-grace (disconnect → pause + grace → rejoin). The grace-window already exists; today it's a silent frozen frame. The overlay makes the pause legible.

Differentiated by role (the key call):

Self (your connection dropped, client reconnecting): centered modal — "RECONNECTING…" + a countdown of the grace remaining + a subtle pulse/spinner for liveness. On reconnect-success → dismiss, resume. On grace-expiry → match-end (disconnected / you lost).
Survivor (your opponent dropped): centered modal — "OPPONENT DISCONNECTED" + "reconnecting… (Ns)" countdown + pulse. On opponent-rejoin → resume. On grace-expiry → "OPPONENT LEFT — YOU WIN" → lobby. (Same closure-principle as the #87 forfeit "OPPONENT FORFEITED".)

What to show: countdown, not indeterminate spinner. The grace-window is bounded, so a countdown ("reconnecting… 6s") tells the player it WILL resolve + when — far less helpless than an open-ended spinner. Pair with a subtle pulse for liveness.

When to fire: after a ~1–1.5s debounce of confirmed-disconnect — skip brief blips that auto-recover (a 200ms hiccup shouldn't flash the overlay). Still down after the debounce → show it.

Where: centered modal, semi-transparent dim over the frozen game (context preserved). A game-halting event → a corner-toast is too easy to miss; the modal halts-and-explains. NOT alarm-red — amber/caution (recoverable pause, not a failure; red is reserved for the final loss).

Reliability-gap (PREREQUISITE flag): the operator's finding — "doesn't fire reliably; not on longer mobile blips; not on page-reload (mobile/desktop)" — is an engine-prerequisite paired with this UX. The overlay is only as good as the disconnect-detection, which must fire across ALL paths: WS-close, timeout, page-reload (the reloading client should auto-rejoin per #12; the survivor sees the overlay meanwhile), and mobile-background/blip (mobile backgrounding drops the socket). Engineer/Shipwright wire-level: detect-all-drop-paths is the prerequisite; this visual-spec assumes detection fires. Flagging the detection-fix as the paired dependency, not part of the visual spec.
