✓ countInFile returns 0 for valid file with no pattern matches

✓ countInFile returns consistent count when same RegExp object is reused

Round 98: findFiles (maxAge: -1 — negative boundary excludes all):
✓ findFiles with maxAge: -1 excludes all files (ageInDays always >= 0)

Round 99: replaceInFile (no-match still returns true):
✓ replaceInFile returns true and rewrites file even when search does not match

Round 99: grepFile (CR-only line endings — classic Mac format):
✓ grepFile treats CR-only file as a single line (splits on \n only)

Round 100: findFiles (maxAge + recursive combined — untested interaction):
✓ findFiles with maxAge AND recursive filters age across subdirectories

Round 101: output() (circular reference — JSON.stringify crash):
✓ output() throws TypeError on circular reference object (JSON.stringify has no try/catch)

Round 103: countInFile (boolean false — explicit type guard returns 0):
✓ countInFile returns 0 for boolean false pattern (else branch at line 443)

Round 103: grepFile (numeric 0 — implicit toString via RegExp constructor):
✓ grepFile with numeric 0 implicitly coerces to /0/ via RegExp constructor

Round 105: grepFile (sticky y flag — not stripped like g, stateful .test() bug):
✓ grepFile with /pattern/y sticky flag misses lines due to lastIndex state

Round 107: grepFile (empty line matching — ^$ on split lines, trailing \n creates extra empty element):
✓ grepFile matches empty lines with ^$ pattern including trailing newline phantom line

Round 107: replaceInFile (replacement contains search pattern — String.replace is single-pass):
✓ replaceInFile does not re-scan replacement text (single-pass, no infinite loop)

Round 106: countInFile (named capture groups — String.match(g) returns full matches only):
✓ countInFile with named capture groups counts matches not groups

Round 106: grepFile (multiline m flag — preserved in regex, unlike g which is stripped):
✓ grepFile preserves multiline (m) flag and anchors work on split lines

Round 113: replaceInFile (zero-width regex /(?:)/g — matches every position):
✓ replaceInFile with zero-width regex /(?:)/g inserts replacement at every position

Round 114: replaceInFile (options.all silently ignored for RegExp search):
✓ replaceInFile ignores options.all when search is a RegExp — falls through to .replace()

Round 114: output (object containing BigInt — JSON.stringify throws):
✓ output throws TypeError when object contains BigInt values (JSON.stringify cannot serialize)

Round 115: countInFile (empty string pattern — matches at every zero-width position):
✓ countInFile with empty string pattern returns content.length + 1 (matches between every char)

Round 117: grepFile (CRLF content — trailing \r breaks anchored regex patterns):
✓ grepFile with CRLF content: unanchored patterns work but anchored $ fails due to trailing \r

Round 116: replaceInFile (null/undefined replacement — JS coerces to string "null"/"undefined"):
✓ replaceInFile with null replacement coerces to string "null" via String.replace ToString

Round 116: ensureDir (null path — fs.existsSync(null) throws TypeError):
✓ ensureDir with null path throws wrapped Error from TypeError (ERR_INVALID_ARG_TYPE)

Round 118: writeFile (non-string content — TypeError propagates uncaught):
✓ writeFile with null/number content throws TypeError because fs.writeFileSync rejects non-string data

Round 119: appendFile (non-string content — TypeError propagates like writeFile):
✓ appendFile with null/number content throws TypeError (no try/catch wrapper)

Round 120: replaceInFile (empty string search — replace vs replaceAll dramatic difference):
✓ replaceInFile with empty search: replace prepends at pos 0; replaceAll inserts between every char

Round 121: findFiles (? glob pattern — converted to . regex for single char match):
✓ findFiles with ? glob matches single character only — test?.txt matches test1 but not test12

Round 122: findFiles (dot escaping — *.txt matches file.txt but not filetxt):
✓ findFiles escapes dots in glob pattern so *.txt only matches literal .txt extension

Round 123: countInFile (overlapping patterns — String.match(/g/) is non-overlapping):
✓ countInFile counts non-overlapping matches only — "aaa" with /aa/g returns 1 not 2

Round 123: replaceInFile ($& and $$ substitution tokens in replacement):
✓ replaceInFile replacement string interprets $& as matched text and $$ as literal $

Round 124: findFiles (* glob matches dotfiles — unlike shell globbing):
✓ findFiles with * pattern matches dotfiles because .* regex includes hidden files

Round 125: readFile (binary/non-UTF8 content — garbled, not null):
✓ readFile with binary content returns garbled string (not null) because UTF-8 decode does not throw

Round 125: output() (undefined/NaN/Infinity — typeof checks and JSON.stringify):
✓ output() handles undefined, NaN, Infinity as non-objects — logs directly

Round 110: parseSessionFilename (year 0000 — Date constructor maps 0→1900):
✓ parseSessionFilename with year 0000 produces datetime in 1900 due to JS Date legacy mapping

Round 110: parseSessionFilename (uppercase ID — regex [a-z0-9]{8,} rejects [A-Z]):
✓ parseSessionFilename rejects filenames with uppercase characters in short ID

Round 111: parseSessionMetadata (nested in context — lazy \S*? stops at first):");
✓ parseSessionMetadata context capture truncated by nested triple backticks

Round 112: getSessionStats (newline-in-path heuristic):
✓ getSessionStats treats absolute .tmp path containing newline as content, not a file path

Round 112: appendSessionContent (read-only file):
✓ appendSessionContent returns false when file is read-only (EACCES)

Round 113: parseSessionFilename (century leap year — 100/400 rules):

✓ parseSessionMetadata captures raw markdown formatting in title without stripping

Round 115: parseSessionMetadata (CRLF line endings — \r\n vs \n in section regexes):

Round 117: getSessionSize (B/KB/MB formatting at exact boundary thresholds):
✓ getSessionSize formats correctly at B→KB boundary (1023→"1023 B", 1024→"1.0 KB") and KB→MB

Round 117: parseSessionFilename (uppercase short ID — regex [a-z0-9] rejects uppercase):
✓ parseSessionFilename rejects uppercase short IDs because regex uses [a-z0-9] not [a-zA-Z0-9]

Round 122: getSessionById (old format no-id — date-only filename match):
✓ getSessionById matches old format YYYY-MM-DD-session.tmp via noIdMatch path

Round 123: parseSessionMetadata (CRLF section boundaries — \n\n fails to match \r\n\r\n):
✓ parseSessionMetadata CRLF content: \n\n boundary fails, lazy match bleeds across sections

Round 124: getAllSessions (invalid date format — strict !== comparison):
✓ getAllSessions date filter uses strict equality so wrong format returns empty

Round 124: parseSessionMetadata (title regex edge cases — /^#\s+(.+)$/m):
✓ parseSessionMetadata title: no space after # fails, ## fails, multiple picks first, empty trims

━━━ Running hooks/evaluate-session.test.js ━━━

=== Testing evaluate-session.js ===

Threshold boundary (default min=10):
✓ skips session with 9 user messages (below threshold)

✓ counts only user messages (ignores assistant messages)

Config file parsing:

✓ handles transcript with malformed JSON lines (still counts valid ones)
✓ handles empty stdin (no input) gracefully

Round 53: CLAUDE_TRANSCRIPT_PATH fallback:
✓ falls back to CLAUDE_TRANSCRIPT_PATH env var when stdin is invalid JSON

Round 65: regex whitespace tolerance around colon:
✓ counts user messages when JSON has spaces around colon ("type" : "user")

Round 85: config parse error catch block:
✓ falls back to defaults when config file contains invalid JSON

Round 86: config learned_skills_path override:

━━━ Running hooks/suggest-compact.test.js ━━━

=== Testing suggest-compact.js ===

Interval suggestion:
✓ suggests at threshold + 25 interval

Environment variable handling:

✓ ignores invalid COMPACT_THRESHOLD (negative)
✓ ignores non-numeric COMPACT_THRESHOLD

Corrupted counter file:
✓ resets counter on corrupted file content
✓ resets counter on extremely large value
✓ handles empty counter file

Session isolation:
✓ uses separate counter files per session ID

Exit code:
✓ always exits 0 (never blocks Claude)

Threshold boundary values:
✓ rejects COMPACT_THRESHOLD=0 (falls back to 50)
✓ accepts COMPACT_THRESHOLD=10000 (boundary max)
✓ rejects COMPACT_THRESHOLD=10001 (falls back to 50)
✓ rejects float COMPACT_THRESHOLD (e.g. 3.5)
✓ counter value at exact boundary 1000000 is valid
✓ counter value at 1000001 is clamped (reset to 1)

Default session ID fallback (Round 64):
✓ uses "default" session ID when CLAUDE_SESSION_ID is empty

Results: Passed: 20, Failed: 0
