fix(web): minimap next turn is disabled at the bottom of a thread - #33038
At the bottom of a thread whose last few turns fit on one screen, the minimap's "Next turn" button stays enabled, and clicking it does nothing. The minimap treats the first user message in view as the current turn, so at the bottom that is not the last turn and a "next" one always exists.
Reproduced on main (ade4730) in the web app: a thread with 8 short turns, 1440×900 and 1100×900, scrolled to the bottom (distance from bottom 0, last 5 turns in view). "Next turn" is enabled; clicking it leaves the scroll position unchanged. "Previous turn" at the top was already disabled correctly.
Change
The timeline records whether its scroll node is at the exact bottom (within 1px) on each minimap refresh, and the minimap disables "Next turn" there. It does not use the 40px follow re-arm zone, because Next can still scroll inside that zone.
The minimap now also refreshes when a thread's remembered scroll position is restored on a thread switch. Without that, switching from a thread left at its bottom to one left mid-history kept the old at-bottom state, and "Next turn" stayed disabled until the next scroll. A layout effect schedules the refresh once the restored position has committed, because a refresh queued during the restore skips until then. The scheduler becomes a stable callback so that effect runs only when the restore state changes.
The minimap also refreshes when the timeline viewport resizes or the list footer changes size (LegendList's onMetricsChange; the footer is not part of the row total). Without that, shrinking the viewport or growing the footer (a queued turn, for example) while detached at the bottom moved the bottom away with no scroll event, and "Next turn" stayed disabled.
"Previous turn", the current-turn choice, the strip highlighting, and the shared disabled button style are unchanged.
MessagesTimeline messages > disables the minimap's next turn button at the bottom of the thread: fails on main (expect(element).toBeDisabled(), received enabled "Next turn"). It also checks that Next is enabled again 30px above the bottom, which fails against a 40px at-end threshold, and that Next is enabled again after a detached viewport shrinks or the footer grows below a detached bottom, each of which fails without its refresh.
MessagesTimeline messages > enables the minimap's next turn button on a thread restored above its bottom: switches from a thread at its bottom to one restored mid-history, then expects Next to be enabled. It fails without the refresh after restoration.
MessagesTimeline.browser.test.tsx and MessagesTimeline.logic.test.ts: 149 passed. vp run check:changed passes.
Evidence
Before = 577c524089 (merge-base), after = 8e252d57cd (this PR merged with main). The code paths these rows exercise are unchanged at b78ce3405f, which differs from the final head only by a main merge outside the timeline (fixture matrix); the thread switch, footer growth and guest page rows, and settled stills for every recorded row, were captured on it in the sections after the recordings. Each side ran its own web dev server on a fresh database seeded with the free Replay provider. Environment: Chrome 157 on Linux in the T3 browser panel, no device emulation, DPR 2, default font scaling, frozen browser clock, 1440×900 CSS px unless noted. Diff0 is RGB difference ×255 (one level visible); DiffT marks differences above 8/255.
After: Next disabled at 0 and 1 px, enabled from 2 px up, and each click lands at the bottom and disables it. Before: enabled everywhere. Previous is disabled at the top on both.
New turns while following, then while detached (1440×900 light)
After: Next is disabled once the followed bottom settles and enabled at the detached position. While following a streaming reply, Next can read enabled at the bottom for a short moment (about 0.2–0.5 s in the samples) until the coalesced refresh runs.
After: disabled Next at the bottom, enabled 120px above. Enter on the focused Next returns to the bottom and the focus ring goes away.
Recaptured on the current head: before d1aeed2492 (merge-base), after b78ce3405f, each side's real web app on a fresh database with synthetic Replay turns, same environment as above. Steps, timestamps and measurements: evidence-r2.md.
After: Next disabled on A, enabled on restored B, disabled again on A, with the in-view strips highlighted. Before: Next enabled throughout, no strips highlighted after a switch.
Footer growth below a detached bottom: follow released at distance 0, then a queued prompt grows the footer 382px with zero scroll events (1440×900 light)
Settled stills on the current head for the recorded rows, pointer on Next (evidence-r2b.md). Only Next differs: disabled at 0 and 1px after the change, the same everywhere else.
Detached viewport shrink, 1440×900 → 1440×500 light, follow released by a wheel at the exact bottom, then the window shrinks with no scroll event (distance 0 → 400px). Steps and timestamps: r01.md.
What else changed: in the bottom-state still pairs (web and desktop), only the Next arrow and its hover background differ at zero threshold. In the shrink row, the previous-to-final stills also differ in one minimap strip highlight (the final head refreshes it after the resize) and in the measurement overlay's disabled text. Elsewhere in the recordings, restored threads refresh their in-view strip highlights, and the focus ring drops when Next becomes disabled. When the viewport height changes with no scroll (a window, panel or composer resize), the in-view strips and the current turn now update too. Clocks, cursor positions and stream timing differ slightly between runs.
Not verified: a real guest share. Creating one needs an active T3 Connect connector, which the capture environment lacks, so the guest row is a labelled harness that renders the real GuestPage and timeline with a synthetic session; Connect authentication and transport are not exercised. Mobile has no minimap.
main merged four times (latest at 61cb845); vp run check:changed passes on 75c218a929.
Review round 1: no code defects; the captures predated the merge and were replaced.
Review round 2: Next stayed disabled after a detached viewport shrank. Fixed in 936834b69f with the extended bottom-state test (red before, green after), captured as the shrink row.
Review round 3: no code defects. Each of the three parts of the fix was removed in turn, and a test failed every time. Open: the guest page has no capture.
CodeRabbit on 4a337eb: the minimap did not refresh when the footer grew below a detached bottom. Fixed in ddd1015009 with the same test extended (red before, green after); captured in the footer growth row.
CodeRabbit on 32ebb8d: a refresh already queued when a restore finished could run before the restored position committed, skip, and leave Next stale. Fixed in e9f6a92157 by scheduling the refresh from that commit; the restored-thread test fails without it. No test covers the race ordering itself, which depends on frame timing.
Proof audit: the matrix was derived from the code; an independent rebuild of the F01 light capture matched with 0 changed pixels; caption timestamps were corrected; the evidence was judged sufficient, with the guest page unverified and not blocking.
Finish round on b78ce3405f (main merged, no conflicts), then main merged again at 6482143a75 without touching the timeline or minimap; vp run check:changed passes on both.
Review round 4: no code defects; both reviewers asked for current captures of the restore, footer-growth and guest paths. Review round 5 on b78ce34 with those captures: both MERGE, no findings. While a followed reply streams, Next can still flicker enabled for a moment until the smooth scroll settles (only visible on hover), as noted in the F13 row.
Proof audit: fixture matrix rederived (matrix-r2.md); the thread switch, footer growth, guest harness and settled boundary, top, interior, growth and hover-rail stills were captured on b78ce34; independent rebuilds of the guest and 0px captures matched with 0 changed pixels; verdict sufficient (report). Unverified: a real guest share over T3 Connect.
AI-assisted; verified with the tests and tools listed above.
At the bottom of a thread whose last few turns fit on one screen, the
minimap's current turn is the first one in view, so "Next turn" stays
enabled although the timeline cannot scroll any further. This test
reproduces #33027 and fails on main.
AI-assisted; verified with the tests and tools listed above.
The minimap's current turn is the first user message in view, so at the
bottom of a thread whose last turns share one screen, "Next turn" stayed
enabled and clicking it did nothing. refreshMinimap now also tracks
whether the timeline is at its end, using resolveTimelineIsAtEnd, and the
minimap has no next item there. Fixes#33027.

A thread switch could keep the previous thread's at-bottom state and leave
Next turn disabled mid-history until the next scroll.

The at-bottom state was only refreshed on scroll and content size changes,
so shrinking the viewport while detached left Next disabled 600px above the
bottom. The viewport resize observer now schedules a minimap refresh too.

Refresh the minimap when the footer size changes.
When follow is released at the bottom, expanding the queued-turn footer can move the bottom without a scroll event or row-size change. minimapAtEnd then stays true, so Next turn remains disabled even when another turn is available.

LegendList keeps the footer size out of totalSize, so a growing footer moved

Refresh the minimap after positioning commits
If a refresh is already queued when restoration finishes, it can run before positionedThreadKey commits and return at the restore guard. When the previous thread was at the bottom, Next turn can remain disabled on the restored thread until another refresh occurs. Schedule a refresh after the positioned state commits.

* feat(opencode): track native image job outcomes and previews (pingdotgg#34089)
OpenCode image-generation tool success acknowledges a launched background job. Keep that job pending until its native outcome arrives, retain the outcome on the original tool item, and serve size-limited image previews through existing rendering and remote file paths.
Recover outcomes after stream loss, allow later exact-path notices to add previews, and clear descendant image tasks from parent rosters on completion or transport failure. Keep older-server fallback and the pinned SDK.
Validation: check:changed passed with 147 tests; required CI passed and review findings were addressed on 62addc8. Client screenshots use controlled fixtures; no paid image generation was used.

* feat(opencode): track native shell jobs across turns
## Problem
OpenCode shell tools can return when a background command launches. T3 now keeps that command in its existing background activity UI until it exits or is stopped, retains captured output, and preserves native completion notifications and continuation turns.
## Change
The adapter scopes tracking and Stop to the owning session and its descendants. Recovery uses the experimental shell-job inventory on OpenCode 2.2.6+, with shell-list fallback on supported older servers. After a cold resume, recovered output, terminal state, and idle roster snapshots persist through the existing session event pump before another turn starts. New session-scoped activity is restricted to attached threads and uses the persisted run identity when available so it stays in the current timeline. Polling reads run outside the adapter lock, with stale results discarded after Stop, exit, or another read. Recovery and Stop retain bounded I/O. Final reads retain the output tail, including diagnostics beyond the first four pages. The SDK remains pinned to 2.0.28, and main's native goals, todo checklists, and image jobs are preserved.
## Scope and approval
Maintainer-directed implementation of native OpenCode background shell tracking from the T3 Code handoff. Scope covers shell lifecycle, output retention, recovery, ownership, and Stop using existing background activity services and rendering. The session event pump extension is needed to persist recovered activity while no turn is active. No SDK upgrade, new UI, or provider-wide infrastructure is included. The author, Yash-Singh1, is explicitly listed in the repository's [contribution-triage exemptions](https://github.com/pingdotgg/t3code/blob/main/.github/TRIAGE_EXEMPTIONS.td), verified against upstream main.
## Verification
Validation: `vp run check:changed` passes. Focused regressions cover output paging, exit codes, idle recovery, persisted run anchors, ownership, cancellation failures, and a stalled poll that must not block turn completion or Stop. Real OpenCode UI turns used MiniMax M3.1 Flash Free against isolated development state and covered launch, Details and retained output, natural completion, continuation, and explicit Stop. Cold-idle persistence and remote-server paths use protocol fixtures; native mobile was not exercised.

Problem
At the bottom of a thread whose last few turns fit on one screen, the minimap's "Next turn" button stays enabled, and clicking it does nothing. The minimap treats the first user message in view as the current turn, so at the bottom that is not the last turn and a "next" one always exists.
Reproduced on main (ade4730) in the web app: a thread with 8 short turns, 1440×900 and 1100×900, scrolled to the bottom (distance from bottom 0, last 5 turns in view). "Next turn" is enabled; clicking it leaves the scroll position unchanged. "Previous turn" at the top was already disabled correctly.
Change
The timeline records whether its scroll node is at the exact bottom (within 1px) on each minimap refresh, and the minimap disables "Next turn" there. It does not use the 40px follow re-arm zone, because Next can still scroll inside that zone.
The minimap now also refreshes when a thread's remembered scroll position is restored on a thread switch. Without that, switching from a thread left at its bottom to one left mid-history kept the old at-bottom state, and "Next turn" stayed disabled until the next scroll. A layout effect schedules the refresh once the restored position has committed, because a refresh queued during the restore skips until then. The scheduler becomes a stable callback so that effect runs only when the restore state changes.
The minimap also refreshes when the timeline viewport resizes or the list footer changes size (LegendList's
onMetricsChange; the footer is not part of the row total). Without that, shrinking the viewport or growing the footer (a queued turn, for example) while detached at the bottom moved the bottom away with no scroll event, and "Next turn" stayed disabled."Previous turn", the current-turn choice, the strip highlighting, and the shared disabled button style are unchanged.

Before = 577c524089 (merge-base), after = 8e252d57cd (this PR merged with main). The code paths these rows exercise are unchanged at b78ce3405f, which differs from the final head only by a main merge outside the timeline (fixture matrix); the thread switch, footer growth and guest page rows, and settled stills for every recorded row, were captured on it in the sections after the recordings. Each side ran its own web dev server on a fresh database seeded with the free Replay provider. Environment: Chrome 157 on Linux in the T3 browser panel, no device emulation, DPR 2, default font scaling, frozen browser clock, 1440×900 CSS px unless noted. Diff0 is RGB difference ×255 (one level visible); DiffT marks differences above 8/255.

What else changed: in the bottom-state still pairs (web and desktop), only the Next arrow and its hover background differ at zero threshold. In the shrink row, the previous-to-final stills also differ in one minimap strip highlight (the final head refreshes it after the resize) and in the measurement overlay's disabled text. Elsewhere in the recordings, restored threads refresh their in-view strip highlights, and the focus ring drops when Next becomes disabled. When the viewport height changes with no scroll (a window, panel or composer resize), the in-view strips and the current turn now update too. Clocks, cursor positions and stream timing differ slightly between runs.

Verification log
main merged four times (latest at 61cb845);
vp run check:changedpasses on 75c218a929.Review round 1: no code defects; the captures predated the merge and were replaced.
Review round 2: Next stayed disabled after a detached viewport shrank. Fixed in 936834b69f with the extended bottom-state test (red before, green after), captured as the shrink row.
Review round 3: no code defects. Each of the three parts of the fix was removed in turn, and a test failed every time. Open: the guest page has no capture.
CodeRabbit on 4a337eb: the minimap did not refresh when the footer grew below a detached bottom. Fixed in ddd1015009 with the same test extended (red before, green after); captured in the footer growth row.
CodeRabbit on 32ebb8d: a refresh already queued when a restore finished could run before the restored position committed, skip, and leave Next stale. Fixed in e9f6a92157 by scheduling the refresh from that commit; the restored-thread test fails without it. No test covers the race ordering itself, which depends on frame timing.
Proof audit: the matrix was derived from the code; an independent rebuild of the F01 light capture matched with 0 changed pixels; caption timestamps were corrected; the evidence was judged sufficient, with the guest page unverified and not blocking.
Finish round on b78ce3405f (main merged, no conflicts), then main merged again at 6482143a75 without touching the timeline or minimap;
vp run check:changedpasses on both.Review round 4: no code defects; both reviewers asked for current captures of the restore, footer-growth and guest paths. Review round 5 on b78ce34 with those captures: both MERGE, no findings. While a followed reply streams, Next can still flicker enabled for a moment until the smooth scroll settles (only visible on hover), as noted in the F13 row.
Proof audit: fixture matrix rederived (matrix-r2.md); the thread switch, footer growth, guest harness and settled boundary, top, interior, growth and hover-rail stills were captured on b78ce34; independent rebuilds of the guest and 0px captures matched with 0 changed pixels; verdict sufficient (report). Unverified: a real guest share over T3 Connect.
