- instrumented cold v1.3.88 proved the lifespans are 141ms even cold; the ~18s
cold gap is a backgrounded create_task blocking the event loop AFTER lifespan
startup but BEFORE uvicorn reports ready (what the health probe waits on)
- add [perf] entry/segment logs to the post-startup background tasks: mcp refresh,
skill refresh, 9router ensure (+ prelude bisection), and svc._post/_post_or_spool
- logging only, no behavior change; next cold log names the exact blocking call
- audited all 16 lifespans + the service client in source: every body is trivial
(yield / makedirs / early-return migrate / fire-and-forget svc.sync)
- the no-op debug() shipped and verified live but cold stayed 21.5s, so the
DEBUGLETON scan was not the cold driver; residual ~16s is cold first-run paging
- next cold build with the new [perf] markers pins it or confirms distributed I/O
- debug(sub_app.name) is a no-op in packaged builds, so the packaged backend.log
had zero per-SubApp markers and a cold stall could only be guessed at
- wrap each enter_async_context with time.perf_counter + a flushed [perf] print,
plus a lifespans-total line, so a cold launch names the exact slow lifespan
- logging only, no functional change; loop logic validated warm
- first debug() call instantiated Debugleton -> recursive os.scandir project scan on the boot path (~17s cold, ~80ms warm)
- early-return when OPENSWARM_PACKAGED=1; dev keeps the full debugger; debug() returns None so callers are unaffected
- validated: with the flag debug() no-ops (no scan); debugger is pip-installed from repo/debugger at build so this ships
- cold 21.4s WITH exclusion vs 22.5s without; items 1+3 also no change
- two defender-targeting fixes both ~0 -> residual cold is disk I/O + interpreter init + squirrel first-run, not AV
- recommend removing the exclusion (weakened AV for no gain); bank the wins (cold 54-138->22s, warm 9-10->5s)
- zip-stdlib + pyc-only gave no cold improvement (cold is native-binary-scan-bound)
- keep build lean; scripts stay as drafts; cold lever is the opt-in defender exclusion (item 5)
- python-env 13554->9285 files (31% fewer) but cold stayed 22.4s vs 22.5s
- cold is native-binary-bound (claude.exe 242MB + .pyd/.dll), not file-count; zip/pyc only touch pure-python
- real cold lever is item 5 (defender exclusion) or trimming native deps; warm 5s already under goal
- download 371.5MB @ 27.1MB/s, authenticode valid; install 6.3s
- cold 22.6s, warm 5.0s, asar 2.1MB, skills live total=17 -- all on the signed 1.3.86 build
- pre-extracting ~30k files into resources blew the windows build past 50min (squirrel lzma on tiny files) + bloated the installer
- revert step 4b to a single node_modules.<digest>.tar.gz (mirrors mac); runtime extracts to warm cache in the background at startup (off the create path)
- runtime _bundled_extracted_modules() stays as a harmless fallback (returns None -> tar path)
- inventory: 607MB asar was ~605MB duplication (python-env 408MB + build-staging 197MB)
- both already ship unpacked in resources/; runtime reads resources/, never the asar
- add build.files exclusion -> asar ~607MB -> ~2MB; kills the 639MB cold-read on first launch
- add inspect_asar.js inventory tool; validate asar size + boot on a packaged exe
- standalone, dry-run by default, NOT wired into the release build (build-gated)
- strips 3352 .py (26.9MB) from site-packages to sourceless .pyc; mechanism proven on bundled 3.13
- scope: site-packages only (keeps backend source for the debugger); validate on a packaged exe
- standalone, dry-run by default, NOT wired into the release build (build-gated)
- collapses ~910 loose stdlib files into python313.zip (cpython auto-adds it to sys.path)
- validate on a packaged exe before enabling; see docs/perf/winv2
- step 4b builds node_modules natively and robocopies it into resources (digest-tagged)
- runtime junctions straight at it; kills the ~14s first-app extract; non-fatal on failure
- service lifespan was awaiting ensure_9router (~7.4s, up to ~18s cold) on the boot path
- dispatch already ensures it lazily; serialize ensure_running so no double-spawn
- cuts warm backend-ready ~9-10s toward ~2-3s
- frontend-only apps no longer need git bash; kills the [WinError 2] preview failure
- windows-only, falls back to bash run.sh for backend apps or when vite is absent
- _link_node_modules falls back symlink -> junction -> copy (no admin needed)
- _ensure_warm_cache prefers a pre-extracted resources tree, zero first-app extract (#9 item 2)
- falls back to tar/npm when absent so mac/older builds are unchanged; add tests
