Converge feat/macos-memory-work with master - #53
Merged
Conversation
Native SDK branch macos-memory-shared-renderer-prep (600d6cf6) carries the autorelease-pool, analytic-rounded-clip, and Metal tiled-image memory work; the tiled-image change still needs live verification. The briefs scope the two follow-up passes: the error-propagation seams (partially landed via #43) and the receipt sweep over every numeric limit. The shared-renderer experiment plan lives in the handoff doc accompanying this work.
The branch is now the complete working set for the macOS memory / shared-renderer work: docs/macos-memory-handoff.md is the entry point (diagnosis so far, phased experiment plan, falsification gates), and myclock/ is the clean isolated-benchmark fixture the bakeoff harness and Phase 0/1 measurements use.
…partially rescinded Myclock on Mac15,6 (M3 Pro, macOS 26.5.2) measures 125 MB with 85 MB dirty owned-unmapped-graphics on this exact branch state, while bare Metal/IOSurface window probes on the same machine cost 9.7/8.5 MiB. The Air's Phase 0 probes were honest but window-scoped; the wall is in what Weaver's renderer does, not in the Metal entry fee. New evidence-led investigation order appended for the next agent.
The handoff doc keeps the correction (the finding that rescinds the Phase 0 gate); the investigation of what allocates the 85 MB is separate work for the Mac15,6 machine and lives in docs/gpu-ledger-wall-brief.md, with its own end state, evidence-led order, and stop rule.
Bare probes on Mac15,6 turn the ~85-96 MB owned-unmapped-graphics ledger on and off with no weaver code: sustained Metal command submission at >=1 Hz commits a ~95 MB per-process driver arena (presentation and window not required; offscreen clears reproduce it), reclaimed within seconds of submission silence. IOSurface-on-CALayer presentation with no in-process Metal never touches it, even at 60 Hz updates. Weaver pins the arena forever because renderFrame presents unconditionally at 60 Hz. Receipt, probe matrix, and the recommendation recorded in the brief; probe sources archived under .zig-cache/macos-memory/gpu-ledger-wall/. The shared-renderer decision stays with Dara per the brief's stop rule.
The handoff's stopped plan is un-stopped: the GPU-ledger brief's probes named the 85 MB (per-process Metal submission working set, paid by whoever submits, ~0 for device-less IOSurface widgets), and Dara re-approved the shared-renderer architecture on that receipt. Phase 1 is the next work; its gate expectation is restated for M3-class machines where the arena inflates the old Air-calibrated totals.
One file scoped to the 2026-07-30 session: the subscription-fee mental model, the probe method that produced the on/off receipt (sustained- cadence probes, exact-config matching, ledger-category cross-checks, PID discipline), what the finding settles, and the corrections it makes to prior session records. Durable state stays in the handoff and the GPU-ledger brief; this is the lessons file.
Phase 1 runs on Mac15,6 where the arena exists. The gate becomes categorical: no submission arena in any widget process (graphics ledger ~0), widget total judged as content cost. Widget side submits no Metal; event-driven presenting stays out of the spike; host shape expectations from the N-layer probe recorded.

master carries the improved signal-based myclock at examples/myclock with a portable tsconfig; the root copies were the pre-move originals and the tsconfig pinned an absolute machine path. myclock/dist stays: the bakeoff harness consumes the built bundle.
📝 WalkthroughWalkthroughThe macOS host recovery smoke test retries pause commands, arms provider-send failure after initial endpoint capture, and validates that a new command-resolution callback occurs after Widget replacement. ChangesRecovery smoke test
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The macOS smoke test can pass on a stale or unrelated callback instead of proving that the replacement widget recovered, and its polling repeatedly rescans all logs during the wait. The contract documentation also remains inconsistent with the intended retained-path guidance, so these issues should be fixed or explicitly accepted before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Greptile SummaryThe duplicate provider-path documentation was removed while preserving the complete guidance on signal mapping, memoization, and stable projectors. Confidence Score: 5/5No blocking failure remains. The documentation check confirms that the retained provider guidance is complete and no accepted blocking findings remain.

Both lineages added near-identical guidance; master's copy carries the map-memoization and stable-projector detail, so it is the one that stays.

The send-failure marker was armed before installing the fixture, whose single transport attempt fired two seconds after launch. Capturing the pre-crash Widget relied on a status.json snapshot landing inside the window between the first provider frame and that attempt; on a slower runner the first qualifying snapshot was already the replacement, and the wait for a second crash that cannot happen timed out. Both 2026-08-16 CI runs and a local reproduction failed exactly there. Install first, capture the pre-crash pid and endpoint from settled status, then arm the marker; the fixture now retries pause every two seconds so a post-arm attempt consumes it deterministically. The final wait counts command resolutions logged after the replacement was captured instead of matching resolved:false literally - the recovered channel's contract is that a callback arrives, and the boolean only reflects whether the machine has a live media session.

254-258: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winAvoid rereading all widget logs on every poll.
waitFor()polls every 50 ms. Each poll rereads and concatenates every.logfile, then splits the full contents. A 10-second wait can perform about 200 full scans and allocate data proportional to the complete log directory.Poll the replacement Widget's log with an incremental offset, or use a dedicated recovery marker.
As per coding guidelines, widget memory and CPU performance are core product requirements; target performance that matches or exceeds Rainmeter.
