Replace JSON-interpolated child JavaScript with fixed preload and summarizer programs. Pass paths and dates through dedicated fixture environment variables; use a fixed quoted exec wrapper so configured executable and script paths remain data. Preserve real Date.now, deadlines, calendar rollover, captured resume metadata and no-next-day duplicate assertions. Actual13/0 Node18.20.8, Node20.20.2 with Bun setting and Node24.9.0; actual13/0 with spaces/apostrophes/literal dollar in fixture paths; next-day negative control12/1; lint and diff checks pass. Addresses CodeQL393/394/395 without suppression or dismissal.
The Stop hook captures its session filename date before waiting for a slow summary, while the fixture previously recomputed it after timeout. Advance only the fixture calendar when the fake summarizer starts and assert persistence under the captured date, matching resume metadata, and no next-day duplicate. Keep Date.now, child delay and lifecycle deadlines unchanged. Actual workflow baseline and corrected fixture13/0; mismatched-day lookup negative control12/1; Node20 with Bun setting and Node18.20.8 both13/0; lint and diff checks pass.
Isolate deadline fixtures from inherited dry-run/disabled hook flags. Remove an unapproved emoji from the new routing regression to satisfy Unicode validation.
The regenerated summary block embeds raw user-message text and was passed
as the *replacement* argument to String.prototype.replace, where $-sequences
($&, $$, $`, $') are special. A user message containing $& re-injected the
entire matched block (duplicating the summary markers) and $$ collapsed to $,
silently corrupting the persisted session summary. buildSummarySection only
escapes newlines and backticks, not $.
Fix: use function replacers (() => summaryBlock) at both rewrite sites so the
replacement text is treated literally. Adds an end-to-end regression test.
