A decoder sizes an image from its header, so the row grows as soon as the
first bytes are parsed -- measured here at 421ms against a load event at
2407ms. Marking the row only once load fired left that first and largest
growth outside the compensation window, and scrolling back through history
still moved the reader by the full image height.
Rows are now marked from the moment an image mounts until loading finishes,
counted so a message with several images stays marked until the last one is
done. The listener also moves to the document: rows announce their images
while mounting, before a ref-driven listener on the timeline element would
exist to hear the first one, which is why the mount signal was being lost.
The fixture serves a real PNG and holds the response open, so the row grows
long before load the way a large image does; an SVG served in one shot lays
out and fires load together and cannot reproduce this. A companion assertion
checks the fixture still has that gap, so it cannot quietly stop testing the
timing it exists to test.

The Electron suites were only reachable one npm script at a time, so a new
one was covered by whoever remembered it existed. test:electron:all builds
once and runs all five, reporting a single summary and a non-zero exit.
The runner lives under tests/ rather than app/scripts/, which .gitignore
excludes entirely.
The image row spacing assertion also stops hard-coding the current gap --
it had 0.59px of headroom -- and calibrates against the spacing the rest of
the timeline is using.

The wide-image probe resolved only from a load handler that a regression
could keep from ever firing, and it was awaited bare, so a broken build
hung the run instead of reporting a failure. Every renderer probe now runs
against a deadline, the probe rejects on image error, and the suite as a
whole is bounded.
Adds a held image endpoint so an above-viewport image can be made to finish
at a moment the test controls, and asserts the reader does not move -- both
at rest and mid-gesture, which is where it regressed.

Mark absolute Markdown links and inline-code relative paths as file
references, resolve them against the originating message cwd, and open
them in the configured editor. Local links no longer navigate the SPA
away from the running renderer.
The canonical transcript assembly projected messages down to seven
fields, so cwd and session_id never reached the renderer. Both are added
to SessionDetailMessage: cwd because the working directory can change
mid-session, session_id because it scopes which roots a reference may
resolve inside. The main process derives those roots from the database
rather than trusting anything the renderer sends.

Publish real virtual-row measurements while suppressing momentum-breaking scroll writes, then reconcile the reader anchor once scrolling settles. Keep live patches out of the timeline during active gestures and add Electron coverage for tall-row overlap, residual motion, and existing-message updates.
Cache semantic timeline anchors and disclosures per session instead of relying on KeepAlive. Restore state after virtualized layout stabilization while preserving explicit focus and tail-follow behavior.
Add @obelisk-apps/cli with the existing build, search, query, and attune contract plus official skill installation.
Separate the docs-only skill artifact, bootstrap installer, release layout, cross-platform CI, and package-level regression coverage.
Defer and coalesce global catalogue refreshes while SessionDetail is active, carry session metadata through incremental patches, and gate in-flight catalogue commits by route. Harden the virtual timeline cold-open and user-scroll lifecycle, and add Electron frame, continuity, metadata, and overlap regressions.
Discard virtualizer measurement corrections suppressed during an active user gesture instead of replaying stale offsets at scrollend. Preserve post-scroll live anchoring and add unit plus Electron coverage for ordinary scrolling without updates.
Track real user scrolling through scrollend with a quiet watchdog, defer timeline commits and virtualizer corrections until settlement, and make SessionDetail the sole tail-follow owner. Add unit and Electron regressions for scroll writes, reader anchoring, near-tail escape, explicit navigation, and flap timing.
Virtualize SessionDetail rows behind stable presentation boundaries and apply typed incremental patches only after visible commits. Preserve reader state across live updates, handle coalesced and reordered patches, and verify the 120Hz append path with Electron tracing.
Render SessionDetail through measured dynamic-height virtual rows while preserving disclosure state, UUID navigation, reader anchoring, and tail-follow across live updates.
Add focused state/reconciliation tests plus a production Electron harness covering long-session DOM bounds, scrolling performance, offscreen navigation, and live viewport stability.
Implement the full ADR-0006 plan: three-layer separation of transaction
correctness, retry policy, and cross-process writer coordination.
Layer 1 — scripts/tx.ts (transaction correctness):
- runWriteTransaction executes work exactly once; no internal retry.
- BEGIN IMMEDIATE takes the write lock up front (avoids SQLITE_BUSY_SNAPSHOT).
- Guarded rollback: checks inTransaction() via adapter before attempting
ROLLBACK; never masks the primary exception.
- WriteTxDiagnostics attached to errors: phase, code, label,
rollbackSucceeded, rollbackError, transactionActive.
- Binding adapters (betterSqliteTransactionAdapter, nodeSqliteTransactionAdapter)
mapping better-sqlite3's `.inTransaction` and node:sqlite's `.isTransaction`.
- configureConnection centralizes WAL + synchronous + busy_timeout.
Layer 2 — scripts/write-coordinator.ts (retry policy):
- runRetryableWriteTransaction: bounded retry with total time budget.
- Only retries when the transaction confirmed ended (transactionActive=false)
and the error is SQLITE_BUSY during work/commit phase.
- BEGIN-phase BUSY = abort entire build (isBeginBusyFailure); the caller
returns `{ deferred: true, reason: 'writer_busy' }` instead of waiting.
- hasUnusableTransaction detects a still-active transaction after failure;
aborts the build immediately, never retries.
Layer 3 — scripts/writer-lease.ts (cross-process coordination):
- acquireWriterLease: dedicated writer.lock.sqlite with busy_timeout=0 +
BEGIN IMMEDIATE. Non-blocking attempt; bounded wait with retryDelayMs.
- writerLockPathFor derives lock path from the target DB path.
- Lease held for the entire build; released on completion or failure.
- Lock DB uses DELETE journal (not WAL); crash/close auto-releases.
- All consumers obey: skill acquires at build start (returns deferred if
unavailable); app daemon (via worker) acquires for its build cycle.
Build semantics changes:
- affectedSessionIds updated only after successful commit.
- BuildIndexResult gains skipped/skippedFiles for observability.
- Skill finalize failure now fails the build (was silently warned).
- Checkpoint changed to PASSIVE (TRUNCATE reserved for maintenance/exit).
- Skill buildIndex returns { deferred, reason } on lease contention;
indexer-service reschedules the build (deferredRetryMs) without publishing
a heartbeat (so the build-deferred state is visible to cross-process
arbitration).
- Service publishes heartbeat immediately on start() for correct arbitration.
Tests:
- tests/write-transaction.test.mjs: single-shot execution, diagnostics
propagation, auto-rolled-back transaction detected, rollback failure
captured as metadata, BEGIN IMMEDIATE semantics.
- tests/writer-lease.test.mjs: acquire/release, contention returns null,
bounded wait with release during budget.
- tests/app-writer-lease.test.mjs: better-sqlite3 adapter integration.
- tests/app-rollback-guard.test.mjs: rewritten — transient BUSY recovered
by coordinator, persistent BUSY skips file, begin-busy aborts build,
live-transaction aborts build, phantom affectedSessionIds prevented.
- tests/daemon-arbitration.test.mjs: skill defers to fresh app heartbeat,
builds when heartbeat is stale.
- tests/app-indexer-service.test.mjs: new cases for deferred-retry
scheduling and immediate heartbeat on start.
- app/tests/electron-concurrency.mjs + child: dual-child IPC structure for
real better-sqlite3 contention (holder acquires lock → build child starts
→ delayed release → result collected; persistent contention bounded).
ADR-0006 updated to reflect the implemented design.
