- findFiles with both maxAge AND recursive combined (option interaction test)
- parseSessionMetadata truncates item text at embedded ### due to lazy regex
- cleanupAliases callback returning 0 (falsy non-boolean) removes alias via !0 coercion
Total tests: 860
- replaceInFile returns true even when pattern doesn't match (silent rewrite)

- getSessionById(null) throws TypeError at line 297 (null.length)
- parseSessionFilename(null) throws TypeError at line 30 (null.match())
- findFiles with maxAge: -1 deterministically excludes all files

returns null because split('@')[0] yields empty string
- getPackageManager skips empty string CLAUDE_PACKAGE_MANAGER via
falsy short-circuit (distinct from unknown PM name test)
- session-end buildSummarySection includes Tools Used but omits
Files Modified when transcript has only Read/Grep tools
Total tests: 842
- getSessionStats: drive letter without slash (Z:nosession.tmp) treated as content
- countInFile: case-insensitive regex with g flag auto-appended (/foo/i → /foo/ig)

Total tests: 833
- Test readStdinJson timeout path when stdin never closes (resolves with {})
- Test readStdinJson timeout path with partial invalid JSON (catch resolves with {})
- Test saveAliases backup restore double failure (inner restoreErr catch at line 135)
Total tests: 830
- replaceInFile with empty replacement string verifies text deletion works

Total: 824 tests

- evaluate-session uses learned_skills_path config override with ~ expansion
Round 80: Three previously untested conditional branches:
- session-end.js: entry.message?.role === 'user' third OR condition
(fires when type is not 'user' but message.role is)
- package-manager.js: getExecCommand with truthy non-string args
(typeof check short-circuits, value still appended via ternary)
- validate-hooks.js: legacy array format parsing path (lines 115-135)
with 'Hook N' error labels instead of 'EventType[N]'
- session-manager: deleteSession returns false when dir is read-only (EACCES)
- pre-compact: main().catch handler when HOME is non-directory (ENOTDIR)
- session-end: main().catch handler when HOME is non-directory (ENOTDIR)
Total tests: 828 → 831
Round 73: Add 3 tests for genuine untested code paths:
- session-aliases cleanupAliases returns failure when save blocked after removing aliases
- session-aliases setAlias returns failure when save blocked on new alias creation
- validate-commands silently skips broken symlinks in skill directory scanning
- session-end.js: entry.name/entry.input fallback in direct tool_use entries
- validate-commands.js: "would create:" regex alternation skip line
- session-aliases.js: updateAliasTitle save failure with read-only dir
- session-manager.js: getSessionById with date-only string exercises the
noIdMatch path for old-format sessions (2026-02-10 → 2026-02-10-session.tmp)
- session-end.js: extract user messages from role-only JSONL format
({"role":"user",...} without type field) exercises line 48 fallback
- session-end.js: nonexistent transcript_path triggers "Transcript not found"
log path (lines 153-155), creates session with blank template
Total: 803 tests, all passing
- suggest-compact: 'default' session ID fallback when CLAUDE_SESSION_ID empty
- session-aliases: loadAliases backfills missing version and metadata fields
- post-edit-typecheck: valid JSON without tool_input passes through unchanged
Total: 797 tests, all passing
- utils.test.js: replaceInFile returns false on read-only file (catch block)
- session-manager.test.js: getAllSessions returns empty when sessions dir missing
- package-manager.test.js: getPackageManager falls through corrupted global config to npm default
788 tests total, all passing.
- getAllSessions search matches only shortId, not title/content
- getSessionPath returns absolute path with correct directory structure
- analysisResults handles zero values for all data fields without crash
Round 46: verify getSessionStats recognises C:/ and D:\ as file
paths but not bare C: without slash; verify parseSessionMetadata
only matches lowercase [x] checkboxes (not uppercase [X]).
On Unix/macOS, rename(2) atomically replaces the destination file.
The previous code ran unlinkSync before renameSync on all platforms,
creating an unnecessary non-atomic window where a crash could lose
data. Now the delete-before-rename is gated behind process.platform
=== 'win32', where rename cannot overwrite an existing file.
Cover createdTime/birthtime fallback in session-manager, readStdinJson
error event settled-flag guard in utils, renameAlias rollback on naming
conflict in session-aliases, and saveAliases backup preservation on
serialization failure. Total: 713 tests.
When --global or --project was followed by another flag (e.g., --global --project),
the flag was treated as a package manager name. Added pmName.startsWith('-') check
to both handlers. Added 20 tests across 4 test files covering argument validation,
ensureDir error propagation, runCommand stderr handling, and saveAliases failure paths.
new Date('YYYY-MM-DD') creates UTC midnight, which in negative UTC offset
timezones (e.g., Hawaii) causes getDate() to return the previous day.
Replaced with new Date(year, month - 1, day) for correct local-time behavior.
Added 15 tests: session-manager datetime verification and edge cases (7),
package-manager getCommandPattern special characters (4), and
validators model/skill-reference validation (4). Tests: 651 → 666.
Cover 30-day month validation (Sep/Nov 31 rejection), getSessionStats
path heuristic with multiline content, combined date+search+pagination
in getAllSessions, ambiguous prefix matching in getSessionById, unclosed
code fence in parseSessionMetadata, empty checklist item behavior,
reserved name case sensitivity (LIST/Help/Set), negative limit in
listAliases, and undefined title in setAlias.
Validate args parameter in getExecCommand() against SAFE_ARGS_REGEX to
prevent command injection when returned string is passed to a shell.
Escape regex metacharacters in getCommandPattern() generic action branch
to prevent malformed patterns and unintended matching. Clean up stdin
listeners in readStdinJson() timeout path to prevent process hanging.
- session-manager: clamp offset/limit to safe non-negative integers to
prevent negative offset counting from end and NaN returning empty results
- session-aliases: add success field to cleanupAliases return value for
API contract consistency with setAlias/deleteAlias/renameAlias
The command cross-reference regex /^.*`\/(...)`.*$/gm only captured the
LAST command ref per line due to greedy .* consuming earlier refs.
Replaced with line-by-line processing using non-anchored regex to
capture ALL command references.
New tests:
- 4 validate-commands multi-ref-per-line tests (regression)
- 8 evaluate-session threshold boundary tests (new file)
- 6 session-aliases edge case tests (cleanup, rename, path matching)
- Test valid project-config detection (.claude/package-manager.json)
- Test priority order: project-config > package.json > lock-file
- Test package.json > lock-file priority
- Test default fallback to npm
- Test setPreferredPackageManager success case
- Test getCommandPattern for test and build actions
