Storage truth chain: dataless-file EDEADLK fixes, suspension-aware watchdogs, runtime leak + updater truth - #1140

Conversation
A field diagnostic report showed a machine where every brain action failed with the raw "Unknown system error -11, read" — macOS EDEADLK on a dataless cloud-placeholder file the launchd brain was not allowed to materialize — while the watchdogs killed healthy suspended brains and an idle brain leaked native memory at 4 MB/min. This lane fixes the whole chain: - jsonrpc: internal runtime errors are redacted, logged with the failing path, and reported to auto-diagnostics; raw errnos never reach the UI. - One canonical storage-fault classifier (desktop storage/) with filesystem corroboration; the sync-host loop and the database-open path both use it, including the Windows OneDrive placeholder case. - launchd: MaterializeDatalessFiles on both agents, ProcessType=Interactive on the brain, so background status cannot deny cloud-file reads. - Watchdogs: suspension-aware on macOS and the Windows supervisor; sleep is logged as a suspend gap, never killed as a wedge; CI now parse-checks the rendered PowerShell. - Updater: the restart step verifies runtime identity (version + build hash + no surviving stale process, PID-reuse safe) before claiming success; repair attempts back off and pause during an update window. - Bootstrap: a failed runtime boot drains a teardown stack shared with dispose(), closing the native sqlite handle and stopping every started service — the 4 MB/min idle leak; project scopes get failed-boot backoff. - Memory guard: brain.memory_sample telemetry and a planned idle restart above a configurable RSS threshold, truthfully logged, never a toast. - Diagnostic report: a brain-free storage-environment section (provider class, dataless counts, materialization policy — enums and counts only); auto-send fires on sustained storage faults without needing the account publisher; ade doctor gains a Storage row naming the remedy. - Truthful copy: "sync hasn't started" is no longer "sync is off"; the Connections pane survives unknown future sync states.

the runUpdateTransaction flow to use an explicit maxMs long enough to cover the
full reinstall and all runVerifiedRuntimeRestart attempts, or re-arm the window
before each restart attempt; ensure isUpdateWindowActive remains true until the
transaction completes so opportunistic repair cannot resume mid-transaction.

used by noteRuntimeIdentityMismatch and getStaleMismatchedRuntime with an async

preserve safe PID-reuse and process-exit detection, and ensure failed probes are

What this fixes
A field diagnostic report (anonymous, user-initiated) showed a machine where ADE was effectively unusable: every brain action failed with the raw
Unknown system error -11, read, the watchdog killed a healthy brain after sleep, an idle brain leaked ~4 MB/min of native memory, and a reinstall changed nothing. Root cause: the project's files were dataless cloud placeholders, andread(2)returnsEDEADLK(errno 11 — unnameable by libuv) when the reading process's I/O policy disallows materialization — which launchd applies to background jobs with noProcessType/materialization key.The chain of fixes

Existing installs pick it up via the plist content comparison on the next update/repair. Linux/Windows analyzed: no equivalent needed (reasons in comments).brain.suspend_gap, never a near-miss warning or a SIGKILL; a kill needs the same stale beat seen twice plus a gap the machine's own sleep cannot explain. CI parse-checks the rendered PowerShell onwindows-foundation(first execution of those four tests is this PR's CI run).createAdeRuntime's failure path drains a teardown stack shared withdispose()(native sqlite handle closed, every started service stopped, reverse order). Project scopes get failed-boot backoff (1 s doubling to 30 s), so a failing boot cannot be re-run per action poll. This was the ~4 MB/min idle native leak.brain.memory_sampleevery 5 minutes; a planned idle restart above a threshold (default 1.5 GiB,ADE_BRAIN_RSS_RESTART_BYTES, any-unit zero disables), truthfully logged as a mitigation, never shown as a crash toast.MaterializeDatalessFilesread from the installed plist — enums and counts, never paths); auto-send fires on sustained storage faults without needing the account publisher (the field machine could never phone home — the trigger hung off a publisher that never started);ade doctorgains a Storage row naming the remedy.sync_not_started("sync hasn't started on this computer yet") instead of "sync is off"; the Connections pane guards unknown future states.Documented acceptance
A brain on this build can send
sync_not_startedto a not-yet-relaunched older renderer during the update window; the old renderer's Connections pane summary breaks until relaunch (which the update transaction performs itself). The renderer is now guarded for all future enum additions; version-gating the wire for that transient window was judged complexity in the wrong place. Hosted web is immune (publishHealth: null), iOS never consumes the enum.Verification

Note
High Risk
Touches brain lifecycle (launchd policy, watchdogs, updater identity, SQLite open, JSON-RPC error classification, and idle memory restarts). A mistake can leak native handles, kill a healthy brain, or mis-report storage/auth failures.
Overview
Stops the field outage where a launchd brain could not hydrate cloud-evicted files (
EDEADLK/ “Unknown system error -11”), leaked a native SQLite handle on every failed boot, and got SIGKILL’d after sleep.Storage and service policy. macOS launch agents now set
MaterializeDatalessFiles(brain + watchdog), plusProcessType=InteractiveandLowPriorityIO=falseon the brain; existing plists rewrite on the next install/repair. SQLite open and the sync-host loop share one errno+path classifier so placeholders arestorage_read_failed, not “repairable corruption.” JSON-RPC treats unnamed platform errnos as internal errors first, redacts them on the wire, and logs the failing path.Runtime hygiene.
createAdeRuntimeregisters every acquisition on a teardown stack used by both failed construction anddispose, so retries no longer leak the DB and started services. An idle RSS guard can restart a quiet primary brain (logged as a mitigation, not a crash). Watchdogs on macOS and the Windows supervisor treat machine sleep as a suspend gap and require two consecutive stale heartbeats before kill.Diagnostics.
