Verifies that defensive guards (render-skip, chat cap, dispose, signal
handler cleanup, alert cap, orphan kill) are present in source. These
are structural tests because the leaks manifest over hours of real
usage, not in unit test timescales.
Signal handlers (SIGTERM, SIGINT, beforeExit) were registered on every
session_start but never removed. Over multiple sessions within the same
process, handlers accumulated — each adding another cleanupAll() call
and descendant kill sweep on exit.
Fix: session_shutdown now calls process.off() for each handler before
cleanupAll(), preventing accumulation.
Also: signalCleanup now kills ALL descendant processes (not just those
tracked by bg-shell) to catch bash-tool spawned children.
Alert queue: pendingAlerts is capped at 50 entries to prevent unbounded
growth when background processes generate rapid alerts faster than the
agent consumes them.
pushAlert signature updated to accept null bg parameter for system-level
alerts that don't originate from a tracked process.
Chat component cap: After 100 rendered components, oldest are removed
from the container (session transcript persists on disk via
SessionManager). Prevents unbounded memory growth in long sessions
where thousands of tool calls accumulate DOM-like component trees.
Orphan process prevention: On shutdown, listDescendants(process.pid)
finds ALL child processes (including those spawned by the Bash tool
that bg-shell doesn't track) and kills them with SIGTERM + 500ms
grace + SIGKILL. Prevents orphaned dev servers, build processes, etc.
from persisting after session exit.
Container.render() now returns a stable array reference when output is
unchanged — TUI.doRender() skips ALL post-processing (isImageLine scans,
applyLineResets, differential diffs) when the reference matches.
Loader decouples spinner frame rotation from Text content updates.
Previously every 80ms tick called setText() which invalidated Text's
wrapTextWithAnsi/visibleWidth caches. Now the frame is prepended in
render() while Text caches the message separately.
Text.setText() returns early when text is unchanged, avoiding cache
invalidation on redundant updates.
ToolExecutionComponent.dispose() clears heavy references (image maps,
diff previews, result data) so GC can reclaim memory when components
are removed from the chat history.
Notifications from ctx.ui.notify() and workflow-logger now persist to
.gsd/notifications.jsonl instead of evaporating as transient toasts.
- notification-store: JSONL persistence with 500-entry rotation, atomic
temp+rename rewrites, ref-counted suppress API, disk-synced counters
- notify-interceptor: WeakSet-guarded monkey-patch on ctx.ui.notify
installed at session_start and session_switch
- notification-widget: always-on belowEditor strip showing unread count
- notification-overlay: scrollable Ctrl+Alt+N panel with severity filter
- /gsd notifications command: clear, tail, filter subcommands
- workflow-logger: warnings now also persist to notification store
- web API: GET/DELETE /api/notifications with ?countOnly support
- 16 unit tests covering store, suppress, project isolation, resync
1. Post-execution retry bypass (auto-verification.ts)
- When postExecBlockingFailure is true, skip retry and pause immediately
- Post-exec failures are cross-task consistency issues that retrying won't fix
- Added test in post-exec-retry-bypass.test.ts
2. File path normalization (pre-execution-checks.ts)
- Added normalizeFilePath() to handle ./path vs path equivalence
- Normalizes backslashes, removes duplicate slashes, strips leading ./
- Applied to checkFilePathConsistency() and checkTaskOrdering()
- Added tests for path normalization in pre-execution-checks.test.ts
3. Pre-exec fail-closed (auto-post-unit.ts)
- Added try/catch around runPreExecutionChecks() inside runSafely block
- If runPreExecutionChecks throws, set preExecPauseNeeded = true
- Used logError from workflow-logger (not raw stderr)
- Added test in pre-execution-fail-closed.test.ts
autoStartTime was never saved to paused-session.json, so cross-session
resume always started with autoStartTime=0 and the widget showed no
elapsed timer. Now saved on pause, restored on resume with Date.now()
fallback for old files.
Also fixes widget layout: elapsed/ETA stays on the header line above
the milestone/branch info line.
The enhanced_verification_* preferences were validated and typed but not
included in mergePreferences(), causing project-level overrides to be
silently ignored. This fix ensures project preferences properly merge
with user-level defaults.
Integrates pre/post-execution checks into auto-mode:
- auto-verification.ts: runEnhancedPreChecks/runEnhancedPostChecks integration
- auto-post-unit.ts: pause control flow when blocking checks fail
- Respects enhanced_verification_strict preference for blocking vs warning
Control flow: blocking failures trigger auto-mode pause for user review.
Adds 3 post-execution checks that run after task completion:
- Import resolution: verifies relative imports resolve to existing files
- Export verification: confirms exported symbols are defined
- Type consistency: validates function return types match declarations
All checks follow the permissive-by-default pattern (R012) - warnings don't block.
Adds 4 pre-execution checks that run before each task:
- File ops review: surfaces create/edit/delete intent for manual review
- Read-before-create guard: fails when plan reads a file before creating it
- Package existence: verifies npm packages exist before install attempts
- Interface contract: warns on mismatched function signatures
Includes preference types and validation for enhanced_verification settings.
The welcome screen lines stopped short on wide terminals because
termWidth was capped at 200 columns. Remove the cap so separator
lines extend to the full terminal width.
- Use `git reset --hard <sha>` for rollback instead of `git branch -f`
which fails on checked-out branches and worktrees
- Clear pendingProviderRegistrations after preflush to prevent duplicate
registration when bindCore() runs
- Process Ollama stream content on terminal `done:true` chunks to avoid
truncating trailing assistant text
The system prompt hardcoded ~/.gsd/agent/skills/ paths for bundled skills,
causing ENOENT loops when skills weren't installed at those locations. The
auto-mode loop treated ENOENT as transient and retried indefinitely.
- Replace hardcoded skill paths in system.md with {{bundledSkillsTable}} template
variable, resolved dynamically via resolveSkillReference() at runtime
- Replace hardcoded templates dir path with {{templatesDir}} variable
- Add buildBundledSkillsTable() to system-context.ts — only includes skills
that actually exist on disk
- Export getTemplatesDir() from prompt-loader.ts
- Add Rule 4 to detect-stuck.ts: same ENOENT path seen twice in the sliding
window triggers immediate stuck detection (missing files don't self-heal)
- Add 4 tests for Rule 4 coverage
Closes#3575
- Move new coercion tests to standalone file using node:test +
node:assert/strict (per CONTRIBUTING testing standards)
- Remove tests from legacy complete-slice.test.ts to avoid mixing
test frameworks in the same file
LLMs sometimes pass plain strings instead of the expected object shape
for array fields like filesModified and requires, causing TypeBox
validation to reject the input before the execute function runs. This
adds Type.Union schemas to accept both formats and normalizes strings
to objects with sensible defaults in the execute functions.
Closes#3565
The flat-rate provider guard from #3552 can fail open in two scenarios:
1. Provider alias mismatch — isFlatRateProvider only matched the exact
string "github-copilot", but "copilot" appears as a provider alias
in the codebase. Case variations could also bypass the check.
Fix: add "copilot" alias and lowercase input before set membership.
2. Unresolved primary model — when resolveModelId returns undefined
(stale model ID, registry mismatch), the guard was skipped entirely,
allowing dynamic routing to downgrade models on a flat-rate backend.
Fix: fall back to autoModeStartModel.provider and ctx.model.provider
when primary resolution fails, disabling routing if either indicates
a flat-rate provider.

The prompt injection scan flags "You are now responsible" in
doctor-heal.md as role injection (matches "you are now [a-z]").
This is a pre-existing legitimate prompt instruction, not injection.
