PZ build 42.x dropped the per-line `t:` (microsecond) field and
tightened the spacing between `f:N`, `t:N`, and `st:N,N,N,N>` markers.
The hardcoded `f:\d+,\s+t:\d+,\s+st:` requirement caused every B42
line to fail the parser's LINE regex, leaving ServerLog entries
without their level/prefix and silently disabling
ServerExceptionProblem and ModMissingProblem (the anchorless
EngineVersionInformation still fired against the joined entry text,
which is why the symptom was "one Information, no Problems").
Make `t:N,` optional via `(?:,\s+t:\d+)?` and the comma between
`f:N` and `st:` optional via `,?`. The B41 format remains a strict
match. Add `debug-server-42x-minimal.txt` mirroring the existing
synthetic fixture in the new format, and parameterise
ProjectZomboidServerLogTest with a #[DataProvider] so all four
parser-shape assertions now run against both formats. Spot-check:
analysers emit 3 Problems (2 exceptions, 1 missing mod) and 4
Information entries against the new fixture, identical to B41.

Walks Entry[] once and emits one ErrorContextProblem per ERROR or
WARNING entry, attaching up to 20 entries before and 20 after as
context. Overlapping windows clip the second hit's before- and
after-ranges so no Entry appears in two context arrays. Caps emission
at 500 hits and adds an ErrorContextTruncatedInformation when reached.

Compares consecutive perks-snapshot rows per Steam ID and emits a
SkillProgressionAnomalyProblem for any single skill whose level gained
more than THRESHOLD_DELTA between two snapshots. Login/Logout/LevelUp
event rows are skipped via a perk-pair regex check on the bracketed
event field.
Threshold of 3 reflects PZ's slow leveling pace: typical session bridges
should not produce four-or-more level jumps in a single skill. The
constant is documented inline so operators can tune for modded XP
servers without touching analysis logic.
Synthetic fixture extended with a PlayerSuspect Steam ID carrying two
snapshots: Strength jumps 2 -> 10 (delta +8, triggers), Fitness jumps
2 -> 8 (+6, triggers), Maintenance jumps 0 -> 3 (+3, exactly at
threshold, does NOT trigger). The existing single-snapshot players
remain noise-free.
Sliding-window heuristic over (Steam ID, item code) groups: any window of
THRESHOLD_WINDOW_SECONDS containing THRESHOLD_COUNT or more positive-delta
events for the same player/item pair triggers a Problem. Negative deltas
(drops, transfers out) are filtered. Five events in ten seconds (defaults)
encodes the rule of thumb that legitimate gameplay rarely produces five
identical items in that span.
Constants live as class constants on the analyser so operators can
override via subclass without touching analysis logic; the docblocks
record the justification.
Synthetic fixture extended with a 6-event burst (AdminUser +
Base.Bullets9mm in <1s) and a 4-event sub-threshold group (Player1 +
Base.Plank scattered over 4 minutes) to exercise both paths.
First custom Analyser subclass in this game tree. PatternAnalyser
operates per-entry without cross-entry state, so pairing
'attempting to join' with 'allowed to join' per Steam ID requires a
bespoke pass over the log. The analyser counts attempts and allowed
events per Steam ID and emits a ConnectionFailureProblem for each
player whose attempt count exceeds their allowed count. Unmatched
'attempting to join used queue' rows are surfaced as failures in v1
because a long queue wait is indistinguishable from a real failure
without timing context.
Constructor pre-registers every concrete ProjectZomboid Log subclass so
that detect() can dispatch on filename hint plus content signature.
Data-provider test verifies each of the eleven synthetic fixtures
resolves to its expected Log class via the public Detective surface.
Per-line warnings emitted by the BurdJournals mod, format
'[time] [BurdJournals] LEVEL: message.'. Parser captures time, the
[BurdJournals] tag as the entry prefix, and the LEVEL token. Detectors:
filename match plus content signature on the literal '[BurdJournals]'
tag bracket.
Two row variants: low-level Connection events and player join/disconnect
events. The LINE regex accepts both shapes; analysers route via
CONNECTION (action/index/guid/id) and PLAYER_EVENT (steamid/player/event)
named-group regexes. Detectors: filename match plus content signatures
on either variant.
Free-form English message body with verb-dispatched analyser regexes
(ADDED_ITEM, ADDED_XP, GRANTED_ACCESS, CHANGED_OPTION,
RELOADED_OPTIONS, TELEPORTED). Parser captures only the timestamp,
since the admin name itself can include parentheses or whitespace.
Detectors: filename match plus content signatures on
'added item Base.X in Y's inventory' and 'granted ROLE access level on'.
Two row variants share the file: Safe House toggles ([LOG] Safety:)
and Combat events ([INFO] Combat: ... weapon=... damage=...). Parser
captures time, level, and the subsystem token (Safety|Combat) as the
entry prefix. COMBAT and SAFETY regexes extract structured fields,
including support for negative Z coordinates from basement levels.
Synthetic fixture covers both variants and represents zombie/vehicle/
real-PvP weapon types so analysers can later filter on damage>0 and
weapon!=zombie.
Per-line skill snapshot log; each Login event is paired with a perks
row containing comma-separated Skill=N tokens. PERK_PAIR regex extracts
each pair via preg_match_all for analyser use. Detectors: filename
match plus content signature on the unique '[Cooking=N, Fitness=N,
Strength=N,' prefix of the perks-row bracket.
Per-line world object placement/removal log. LINE pattern handles both
integer and floating-point coordinates and both 'Base.X' and
'IsoObject (X)' object encodings. Detectors: filename match plus content
signature on the added/removed verbs paired with Base./IsoObject prefix.
Per-line item gain/loss event log. Parser captures only the timestamp;
analysers decompose location/delta/item via ItemPattern::FIELDS.
Detectors: filename match plus content signature on the
container/floor/inventory location verbs paired with a signed delta.
Per-line client RPC trace. Parser captures only the timestamp;
analysers decompose steamid/player/command/coords via CmdPattern::FIELDS.
Detectors: filename match plus content signature on the
'steamid "name" command @ x,y,z' line shape.
Strict 5-field bracketed format. Parser captures only the timestamp;
analysers that want steamid/action/player/coords/param decompose the
Line text via ClientActionPattern::FIELDS. Detectors: filename match
plus content signature on the IS{Enter,Exit}Vehicle / ISWalkToTimedAction
action tokens.
Handles both chat-engine events (bracketed level prefix) and bare
server-alert lines via an optional level group. Detectors: filename
match on _chat.txt plus content signatures for ChatMessage{...} log
entries and the chat-server initialization banner. CHAT_MESSAGE and
SERVER_ALERT named-group regexes ride along on ChatPattern for analyser
extraction in phase B.
Concrete Log subclass for the engine debug log. Captures time, level,
and subsystem prefix per entry; stack-trace continuation lines attach
to the triggering ERROR entry via PatternParser's append-on-no-match
behaviour. Detectors: filename match on DebugLog-server.txt plus two
content signatures (the version=X.Y.Z+hash banner and the level/
subsystem/f/t/st header shape). Pattern constants live in
src/Pattern/ProjectZomboid/DebugServerPattern.php with named groups
ready for analyser use in phase B. Synthetic fixture under
test/src/Games/ProjectZomboid/fixtures/ uses zeroed identifiers and
placeholder paths.
Add empty per-component subdirectories under src/{Analyser,Log,Parser,Pattern}/SevenDaysToDie/
with .gitkeep markers, plus SevenDaysToDieDetective stub extending the base Detective with
a TODO body. Smoke test under test/tests/Games/SevenDaysToDie/ asserts the detective is
instantiable. Directory name is alphabetic because PHP class names cannot begin with a digit.
Add empty per-component subdirectories under src/{Analyser,Log,Parser,Pattern}/Hytale/
with .gitkeep markers, plus HytaleDetective stub extending the base Detective with
a TODO body. Smoke test under test/tests/Games/Hytale/ asserts the detective is
instantiable.
Add empty per-component subdirectories under src/{Analyser,Log,Parser,Pattern}/ProjectZomboid/
with .gitkeep markers, plus ProjectZomboidDetective stub extending the base Detective with
a TODO body. Smoke test under test/tests/Games/ProjectZomboid/ asserts the detective is
instantiable.
Add empty per-component subdirectories under src/{Analyser,Log,Parser,Pattern}/Minecraft/
with .gitkeep markers, plus MinecraftDetective stub extending the base Detective with
a TODO body. Smoke test under test/tests/Games/Minecraft/ asserts the detective is
instantiable. Introduces src/Pattern/ as a new top-level component directory.
