Every wrong turn in this work came from trusting a number whose validity had
not been established: a throttled renderer reporting zero rendering work, a
trace category that was never enabled reporting zero long tasks, a scenario
that rendered nothing reporting a perfectly quiet profile, and an 'after'
measured without a matching 'before', which made a no-op change look like a
fix.
The performance skill now puts measurement validity ahead of measurement,
requires a baseline from the unchanged build through the identical scenario,
directs native work to the timeline trace rather than the sampler, requires
unvalidated changes to be reverted and recorded as rejected, and says when to
stop optimising a path that is already inside budget. It also points at the
repository's capture commands.
The sync skill gains the invariant behind the cache-thrash loop: an entry
acquired during render but protected only after commit is unprotected for the
whole render pass, capacity should be a soft target, eviction must not run on
the acquisition path, and raising a limit relocates a cliff instead of removing
it.
Improve OpenChamber responsiveness under large session workloads while fixing
cache, synchronization, and persistence correctness across runtimes, projects,
directories, and worktrees.
- prioritize selected and visible sessions during bootstrap and defer
non-critical enrichment work
- reduce redundant message loading, event processing, store publication, and
hidden sidebar work
- prevent stale session and message requests from overwriting newer
authoritative state
- preserve existing data when authoritative fetches fail instead of treating
failures as successful empty responses
- scope session materialization, messages, drafts, queues, todos, pins,
permissions, folders, tabs, Git state, and pull request data by runtime and
directory identity
- harden runtime switching, reconnect, cleanup, mutation reconciliation, and
persisted-state ordering
- preserve live subagent Task linkage when metadata arrives after an older
message request or while streaming parts are suspended
- coalesce overlapping tail refreshes without losing newer refresh demand
- improve cold-session loading by moving deferrable work out of the critical
bootstrap path
- isolate URL authentication, mobile credentials, native secrets, and other
runtime-owned state across endpoint changes
- bound long-lived caches and remove avoidable allocations from event and
rendering hot paths
- limit virtualization to archive collections where it improves rendering
without disrupting active sidebar layout
- stabilize session folders, pin ordering, expanded state, and persisted
sidebar behavior
- open skill files through the same secure editor and outside-workspace grant
flow used by file navigation, including worktree sessions
- expand regression coverage for stale completions, runtime collisions,
reconnect behavior, persistence races, authoritative empty results, and
subagent refresh ordering
- document the updated synchronization, cache ownership, performance, and
runtime-isolation invariants
Keep always-on instructions concise and route specialized work through focused skills. Split large skills into progressive references and add dedicated change, desktop, sync, and performance guidance.
