Achievements

Planned feature — not released yet. This page is the functional reference for the achievement system designed in issue #530 (engine) and filled by the catalogue issue #833 that follows it. The first part of the page is for players; from Server configuration onwards it is for server operators and contributors, and the Catalogue at the end is for players who do not mind spoilers.

An achievement is a success a player obtains once: a permanent, timestamped record that a player did something notable in Lasers-Enigma — solved a first puzzle, collected every bonus of a chapter, walked five kilometres inside puzzles… It is announced when unlocked and can be browsed in a menu at any time.

When the server enables it, Lasers-Enigma replaces Minecraft's native advancements: players stop earning them, the native screen stays empty, and Lasers-Enigma's own menu is the only achievement interface (see Native advancements).

What an achievement is

Property	Meaning
Obtained once	Unlocked a single time per player. A re-unlock only happens after an explicit admin reset or a full progress reset.
Individual	An achievement is always earned by your own actions or progress — never inherited from a partner or from someone who played the puzzle before you. An achievement may require someone else to be present, but you always have to earn it yourself. Achievements may one day unlock content, so they must prove what you did.
Permanent	Never lost because content changed (a chapter gained a level, a bonus was added, an area was deleted, a plugin was removed). The only things that remove an achievement are a full progress reset and an admin reset. There is no seasonal or automatic reset.
Per server	The play server and the beta server keep separate achievement histories.
Owned by one plugin	Lasers-Enigma owns the achievements about puzzles and statistics; a companion plugin (LEPSU on the play server) owns the campaign achievements about chapters, paths, difficulty tiers and skill — and, more generally, anything that rests on knowledge the engine does not have, such as which levels are built for several players. Every achievement has exactly one owner, which applies the achievement's policies.
Categorised	Each achievement belongs to one category, shown as a tab of the menu with its completion x / N (empty categories are not shown). The engine ships nine, in this order: Firsts · Solver · Bonuses · Together · Dedication · Explorer · Mastery · Race · Mishaps, and the play server adds Campaign, Teamwork and Skill after them, so its three tabs sit together at the end rather than interleaving with the engine's. An achievement registered without a category lands in an Other tab of its own plugin (<namespace>:other) rather than disappearing. Secrets are spread across the categories (there is no Secret tab).
Rarity	onboarding · common · rare · radiant. Presentation only — it decides the colour the title is written in, in four places: the item in the menu, the action bar of a single unlock, and the title inside both the unlock chat line and the server-wide announcement. A line announcing several unlocks at once joins the titles without colouring them, and the unlock sound is the same whatever the rarity. The word itself is never displayed, and nothing in the engine behaves differently because of it.
Optionally hidden	A hidden (secret) achievement shows as ??? in its category — no description, no progress — until it is unlocked, or until its prerequisite unlocks (then it is revealed and displayed like any locked achievement). Hidden achievements count in the total and are never named by any message before you unlock them.
Optionally chained	An achievement may name one prerequisite (for instance 10 puzzles → 25 puzzles → 50 puzzles). The prerequisite orders the menu and the notifications and reveals hidden children; it is not a lock: unlocking the child never requires the parent, and unlocking the child never unlocks the parent.
Optional progress	When it is cheap to compute, the menu shows x / N. An achievement may also declare what its numbers count, and the bar then names it: 37 / 50 puzzles, 47 / 300 minutes, 1 240 / 5000 blocks. That word matters because a threshold does not always count in the unit its description speaks of — Time Flies asks for five hours but counts minutes, Backpacker asks for twenty kilometres but counts blocks — so without it the bar would read 47 / 300 under a sentence about hours. A bar whose unit is obvious from the title keeps the bare x / N. Progress is computed when the menu opens, never stored, and disappears once the achievement is unlocked.

Not part of the system: points or scores, rewards, repeatable achievements, deep achievement trees, a "100 % complete" achievement, percentages.

Unlocking and notification

• An achievement unlocks immediately when its criteria become true, on a discrete game event: winning and leaving a puzzle, a statistic being saved, a companion plugin's own trigger, an admin grant… There is no periodic check.
• Achievements unlocked within the same couple of seconds are announced together, once. Anything a finished run earned you arrives straight away, wherever you are standing: the puzzle is behind you, and waiting for you to be outside every area would mean walking back to the spawn on a server whose hubs are areas too. An unlock earned without finishing a run, such as a feat of optics noticed mid-solve, is held back while you are inside an area so it does not land on the puzzle you are still looking at; it arrives the moment you step out of it, or after five minutes at most if you never do. The announcement itself is a clickable chat block (★ Achievement unlocked: <title> with the description, the title in its rarity's colour, or ★ N achievements unlocked followed by up to three titles, joined plainly; clicking opens the menu), a short action-bar line (the title in its rarity's colour for a single unlock, the bare count for several), and an unlock sound. There is one unlock sound, the same whatever the rarity, and it is the achievements' own short sequence of bells and a chime — no longer the puzzle-victory jingle. It goes through the usual sound customisation hook (see Sound effects), so a server or resource pack can replace or silence it.
• Everyone hears about it: each batch of unlocks earned in play is also announced to the other players, in each one's language, in one chat line: ★ <player> unlocked <title>. for a single unlock, and for a batch ★ <player> unlocked <title>, <title>, <title> and more (N achievements). — at most three titles are named, whatever the size of the batch, and the number in brackets is the total. A hidden achievement is announced as a secret achievement, never by its title. The line carries no sound and is not clickable. Recognitions from history, admin grants and unlocks left over from a previous session are never broadcast. Three independent settings let you stop seeing the other players' lines, stop your own unlocks from being announced, or stop your own notifications (see Player settings).
• The very first achievement you ever receive, whatever the way, adds one extra line telling you where they live: your achievements are in /lasersenigma achievements. On a server that still shows Minecraft's own advancements, the line also says that these are a separate thing from them. It is sent once in a player's life, never again.
• Offline players (an admin grant, a creator achievement earned while absent): the achievement is recorded at once and announced at the next join.
• Recognition from your history: at every join, achievements you already deserve from your existing statistics (for instance 75 unique bonuses) are unlocked without fanfare. Achievements about how a run was played (speed, efficiency, what happened during the run) are never granted retroactively.
• Join summary: offline awards and recognised-from-history awards are merged into one clickable message, a few seconds after joining, naming up to three titles: "★ 3 achievements unlocked while you were away — 2 recognised from your history". Recognised achievements show unlocked from your history in the menu instead of a date.
• Quiet play: a player can turn their own achievement notifications off (see Player settings); achievements keep unlocking, stay visible in the menu, and are marked NEW until seen.
• The tainted-run notice shown at victory (Records are only counted in solo runs.) carries a second line whenever the achievement system is on: Some achievements are not awarded for shared runs either. It is printed on every shared run, not only on the ones that actually cost you something, and it says some on purpose — only a few achievements refuse a shared run (Nothing Escapes and Record Breaker are the two built-ins that do), and a shared run is even worth something of its own: the hidden Tainted Love rewards exactly the run a stranger walked into.

Runs, modes and fairness

Situation	Effect on achievements
Spectator, creative or editor mode; entering a puzzle through its victory area	No run exists, so nothing unlocks. A builder testing their own puzzle earns nothing.
Several players in the puzzle at once (tainted run)	Victory- and bonus-related achievements still unlock. By default, record-, speed-, efficiency- and mechanic-related achievements do not (records are already not counted in tainted runs); each achievement states its own policy. Duo/Trio levels on the play server are not tainted, so those achievements count there too — but each player still earns only what their own actions caused (see Who gets credit?). The taint flag is also what tells playing together apart from being walked in on: a second live run taints a puzzle that was not built for two. Nothing inside Lasers-Enigma ever cancels a taint — only a companion plugin knows which levels are built for several players — so on a server running Lasers-Enigma alone every shared run is a tainted run, and the hidden Tainted Love is the achievement it earns. The opposite achievement, the one for winning a level designed for company, is therefore not the engine's to own (see Catalogue).
A puzzle that was already solved when you walked in (for instance kept open by someone in creative mode)	Your run is marked pre-solved: achievements about the run itself (its time, its actions, its bonuses, what happened in it) are never awarded on such a run. Reset the puzzle and solve it yourself.
Mechanic-based achievements ("send white light through a prism")	Credited to the one player whose own action made the effect appear — see Who gets credit?. Awarded the moment the effect appears, win or not — a mechanic achievement rewards doing something, not finishing the puzzle. The announcement still waits until you leave the puzzle. A few achievements are explicitly about the winning run (their description says so); those wait for a legitimate win.
Admin progress grant (/. progress grant)	Counts as solved levels, so threshold achievements (N puzzles solved, chapters) unlock. Achievements about a real run (time, actions, mechanics) and difficulty-tier achievements never unlock from a grant.
Full progress reset (/lasersenigma progress reset, or the same thing spelled /lasersenigma stats resetProgress allAreasForPlayer / allPlayerForAllArea — confirmation required; lasers.admin, except a whole-player reset aimed at yourself, which needs no permission at all — anyone may start over)	Also deletes the player's achievements, and everything a companion plugin remembers about them: a full reset is a fresh start, and a tally that outlived it would hand an achievement straight back on the next win. The confirmation names how many achievements will be deleted.
Area-scoped progress reset (one area)	Achievements untouched.
Area reset from inside a puzzle	Ends the current run and starts a new one: run-based achievements are evaluated on the new run.
Content change after unlock	Nothing: an unlocked achievement stays unlocked.
Difficulty-dependent achievements	Owned by the play-server plugin. A level's tier is only established after 20 solvers; the achievement is evaluated again when the tier becomes established, so early solvers get it then (quietly, without a server-wide announcement). Descriptions say "a level with an established Legendary rating".
Skill achievements (speed, efficiency)	Owned by the play-server plugin, restricted by a difficulty floor and a per-level game-design decision (see the Eligibility column). Record achievements require the level to already have a few solvers.
Your own levels	Authors are never excluded: you earn achievements on the levels you built like anyone else.
Admin reset	Silent for the player. For a play-server-owned achievement it is undone the next time the plugin re-evaluates it (a test tool, not a moderation tool).

Who gets credit?

Mechanic achievements ("send white light through a prism", "send white light into a prism"…) are credited to the player who made the effect appear: the last player who acted on the puzzle — rotated a component, placed or removed a mirror, placed a portal, grabbed or released a cube, resized a gravity sphere — within about ten seconds before the effect showed up (light takes time to travel across a level). Walking on plates, opening doors or flipping vanilla levers does not count as acting on the puzzle.

• My friend rotated the last mirror. They get it, not you. If you both acted within the ten seconds, nobody gets it: when the game cannot tell who caused it, it credits no one.
• The beam was already going through the prism when I arrived. Nobody gets it. Reset the puzzle and do it yourself.
• I acted, and the effect only showed up much later, or the level moves its own mirrors on a timer. Nobody gets it. Only effects that follow your own action closely, with no timer-driven change in between, are credited. On a level whose components move on a timer, mechanic achievements are simply not available.

This rule is deliberately conservative: it may miss a credit you deserved, but it never gives you one you did not.

The achievements menu

/lasersenigma achievements (aliases /lasers achievements, /le achievements) opens a paginated chest menu:

• one page set per category, the categories acting as tabs showing x / N. The tabs share a single row of nine slots, and that row scrolls: while the categories fit, each one gets a slot; past that the last slot becomes a More categories control that pages through them eight at a time, so no category is ever unreachable, however many a companion plugin registers. The count is not Lasers-Enigma's to bound — it brings nine itself and the play server adds three more;
• one item per achievement: its title, its description (or ???), its state (locked · NEW · unlocked on <date> — in your time zone, localised · unlocked from your history), its progress while locked — x / N, or x / N <unit> when the achievement says what it counts (47 / 300 minutes). An unlocked title is written in its rarity's colour, a locked one in grey;
• a footer row holding the summary item with the total unlocked / total (and the page number when the category needs more than one page), the toggle item for the notification preference, and the page arrows;
• administrators also see each achievement's technical identifier on its item, which is what the grant and reset commands take. It appears only on an achievement the player can already see: a secret that is still ??? shows no identifier at all.

The menu opens anywhere, puzzles included, and needs no permission.

Achievements defined by a plugin that is no longer installed are kept in the database but no longer listed; the total shrinks accordingly and nothing is announced when the total changes.

Player settings

Setting	Command	Default	Effect
My notifications	/lasersenigma achievements notifications on|off (or the menu toggle)	on	off = no chat block, no action-bar line, no sound when you unlock something. Achievements still unlock, remain visible in the menu and are marked NEW until seen. Does not change what other players see.
Announce my unlocks	/lasersenigma achievements broadcasts mine on|off	on	off = your unlocks are no longer announced to the other players.
Others' announcements	/lasersenigma achievements broadcasts others on|off	on	off = you no longer see the server-wide unlock lines of other players.
Time zone	/lasersenigma settings timezone [zone|auto]	your location when the server allows the automatic lookup, otherwise the server's time zone	Used by time-of-day achievements (Nocturne) and by the dates shown in the menu. The argument is optional: without it, the command tells you which zone is currently in use. auto hands the zone back to the automatic lookup and runs that lookup straight away, rather than leaving you on the server's zone until your next join.

These are the first per-player settings of the plugin; the same store will host future per-player preferences.

How the automatic time zone works: when the server enables it, the plugin asks an outside service over HTTPS which time zone your connection's address belongs to, once per player, refreshed monthly, in a background thread. Only the resulting zone is kept; the address is never stored. The service used is ipapi.is, chosen because it is free, needs no account, is hosted in the European Union and states that it keeps no logs of the queries. Because your address does leave the server, the lookup is off by default — see player_timezone_lookup. If the guess is wrong (VPN, travelling), set your zone yourself with the command; a zone you set yourself is never overwritten by a later automatic refresh.

---

Commands

Command	Permission	Effect
/lasersenigma achievements list [player] [page]	none for your own list; lasers.admin for another player	Prints the unlocked achievements with their dates, a page at a time. Unlocked secret achievements are listed by title.
/lasersenigma achievements grant <id> [player]	lasers.admin	Unlocks the achievement for the player (default: yourself). Announced to the player like a normal unlock (not to the server); a no-op if already unlocked. Works for offline players.
/lasersenigma achievements reset <id> [player] confirm	lasers.admin	Deletes that one unlock, silently (a debug tool; the confirm keyword is required). The achievement can be earned again later (immediately, for play-server-owned achievements, without a new announcement).
/lasersenigma achievements resetAll [player] confirm	lasers.admin	Deletes every unlock of that player, silently (a debug tool; confirm required).

<id> is the achievement's stable identifier, <namespace>:<name> (for instance le:first_victory, lepsu:chapter_cleared_solo_2); administrators see it in each menu item's lore. Identifiers are only suggested to administrators. In a command it is typed with a dot instead of the colon — le.first_victory — because Minecraft's command parser rejects a colon in an unquoted argument; tab-completion offers that spelling, and the console accepts either.

Server configuration

From here on, this page is for server operators and contributors.

Key (config.yml)	Default	Effect
achievements_enabled	true	false disables the whole system: nothing unlocks, nothing is written, and the menu, list, grant, reset and resetAll answer "achievements are disabled on this server". The notifications and broadcasts sub-commands are the exception — they record the preference either way, so a player's choices survive the system being switched off and back on. Companion plugins can still register their achievements without error. Existing unlocks are kept and become visible again when re-enabled; run-based achievements missed while disabled are lost, threshold ones are recognised at the next join.
achievements_broadcast	true	false stops the server-wide unlock lines.
vanilla_advancements_hidden	false	Whether the plugin neutralises Minecraft's native advancements for players (see below). Independent from achievements_enabled: with the defaults, Lasers-Enigma achievements and vanilla advancements coexist. The Lasers-Enigma play and beta servers run with true (set on the play server's own configuration, inherited by the beta mirror; the public server pack ships the default). A startup warning reminds operators that vanilla advancement grants no longer complete while it is on.
vanilla_advancements_purge_existing	false	One-shot, irreversible removal of the vanilla advancement progress players already hold, applied once per player at their next join (otherwise veterans keep seeing the tabs they completed before, with frozen progress). Ignored unless vanilla_advancements_hidden is true. The play and beta servers run with true.
player_timezone_lookup	false	Resolves each player's time zone from their connection's address by asking ipapi.is over HTTPS — once per player, refreshed monthly, from a background thread; only the resulting zone is stored, never the address. Off by default because it does send players' addresses to a third party: disclose it in your server rules before you turn it on. The provider was picked for being free, account-free, hosted in the European Union and committed to keeping no query logs. The play and beta servers run with true. When off, players can still set their zone with the command; the server's zone is the fallback.
player_timezone_lookup_url	https://api.ipapi.is/?q={ip}	The service the lookup above queries; {ip} is replaced by the player's address. The answer may be a bare zone id such as Europe/Paris or a JSON object carrying a timezone field, so another provider — or one of your own — can be used without a code change.

Sharing one MySQL database between two live servers is not supported for achievements (each server keeps its own in-memory state).

---

Native advancements

Lasers-Enigma does not use Minecraft's native advancement screen for its achievements, and — when vanilla_advancements_hidden is on — it neutralises the native advancements so that the two systems never coexist:

• Why a plugin-owned menu: the native screen cannot be translated per player (Lasers-Enigma ships 25 languages), cannot be opened by the server, and its content is either global to the server or needs version-fragile packet code (make-or-use study in issue #530).
• How the native advancements are neutralised, by the plugin alone (no data pack, no server configuration): the plugin cancels every vanilla advancement criterion the moment it is granted, for every minecraft advancement except the recipe-book ones. A vanilla advancement therefore never completes: no toast, no chat announcement, no tab in the native screen (a tab only appears once its root advancement is completed), and nothing already earned is destroyed — unless the purge option is enabled. The recipe book keeps working.
• Three possible states for an operator to choose deliberately: hidden + purged (clean, irreversible — the Lasers-Enigma play and beta servers) · hidden only (veterans keep frozen tabs — confusing) · not hidden (the two systems coexist — the default of a fresh install and of the public server pack).
• Side effects: while the neutralisation is on, /advancement grant on a vanilla advancement, other plugins' vanilla advancement grants and advancement-based quest rewards silently do nothing (a warning is logged at startup).
• Server operators who prefer a server-level switch can disable all vanilla advancements in spigot.yml instead (advancements.disabled: [minecraft]), at the cost of the recipe book.

Catalogue

This section is for players who do not mind spoilers, and for contributors.

The two tables below are the single functional reference for every achievement: a row of the Catalogue table plus its row in the Delivery table is meant to be implementable without further questions. They are filled and validated in the catalogue issue #833 (prerequisite: #530's player-surface sub-issue), then kept up to date with each achievement shipped. The built-in achievements Lasers-Enigma ships, across its nine categories, are already listed in full.

One achievement left this catalogue and came back through the front door. Double Slit — win a puzzle built for several players, with someone else in it — was a built-in while V11.1.0 was being written, and was taken out again before it ever shipped: it is gone from the plugin and from its 25 translation files. It required an untainted run, and nothing inside Lasers-Enigma ever cancels a taint: only a companion plugin knows which levels are built for several players. An achievement no server can earn without a companion plugin is that plugin's to own, not the engine's — so LEPSU registers it through the public API as lepsu:two_heads, under an id in its own namespace since le is reserved and refused to every other plugin. It is listed below as a play-server row.

⚠️ Spoiler alert. The tables list every achievement, hidden ones included, with their exact unlock criteria. Read on only if you do not mind knowing.

Naming charter

• Title — the one hard rule: a title is never a plain restatement of what the player did to get it. Win Ten Puzzles is the criteria column with capital letters; Centurion is a title. Everything else below is guidance. Puns, wordplay, elevated or old-fashioned vocabulary, and references to geek, literary or scientific culture (computer science, optics and the physics of light, astronomy, psychology, sociology, philosophy, science fiction), to Portal 2 and to other puzzle games are welcome. Guidance: aim for about 24 characters and three words — that is a house style, not a limit, and nothing truncates a longer one (see Where a title is rendered below) · allude, never quote (a song, film or game phrase used verbatim is a borrowed brand, not a joke of ours) · roughly half the catalogue legible from the game's own vocabulary (light, colour, optics, astronomy), the rest may be deep cuts · never mock the player's competence at the moment the achievement fires (self-deprecation about the game or a shared mishap is fine; a title that lands while the player is failing must be wry, not cruel) · a visible title must not name a component the player meets later in the campaign (if it must, the achievement is hidden — hidden achievements are announced to others as a secret achievement) · two titles must never render the same, or nearly the same, in any of the 25 languages — both plugins share one menu, so the comparison is against the whole catalogue and against the category tab names, not just against the neighbours in a tab.
• A number in a title is allowed. Five Kilometres of Puzzle says five kilometres and is a fine title; what would not be is Walk Five Thousand Steps, which is the criteria read aloud. If the threshold is later re-tuned, the title is re-read like any other — the same as when a description's figure changes.
• Where a title is rendered, and why length is guidance rather than a rule: the action bar shows the title alone, with no prefix, and comfortably fits far more than the catalogue's longest (AchievementController.sendOwnNotification) · the unlock chat line and the server announcement put it in a sentence, and chat wraps · the menu item carries it as an item display name, which Minecraft draws as a tooltip sized to the text and never truncates · the /lasersenigma achievements list page puts it in a chat line too. No render site clips a long title. The longest in the catalogue today is 28 characters (it Cinquanta Sfumature di Laser, uk П'ять Кілометрів Головоломок) and they display correctly.
• Description — the in-game text under the title: one or two short sentences in the imperative, telling the player the thing to do ("Solve your first puzzle.", "Send white light into a prism and take it apart.") rather than narrating it back at them, in the same playful tone. For a visible achievement the description is self-sufficient: it contains the number and every exclusion the player must know (solo runs only), because the player never sees the criteria column. For a hidden achievement it is only revealed once unlocked.
• Mechanic rows — five rules, because credit is individual: (1) active voice with a verb of doing — "send white light through a prism", never "white light is split during your run"; (2) name an act the game can see — rotate, place, remove, drop, resize; (3) never write "solo only" — it is an authorship rule, not a solo rule; write "by your own doing" if anything; (4) no progress formula, ever — partial credit cannot be attributed; (5) one shared credit rule (Who gets credit?) — no description repeats it. A mechanic row is only admissible if the effect appears shortly after the action that causes it; a duration or delayed consequence must be measured from its start.
• Translations — 25 languages. Every title carries a translator context note (the Context column) explaining the reference and the intent; translators translate the spirit, not the words and may substitute a locally legible reference; a language may keep the English title when no equivalent exists. Singular and plural notification forms are separate entries.
• Notification — a fixed template, not a per-achievement text: ★ Achievement unlocked: <title> + the description + the clickable menu link (titles only when several unlock together).
• Families — one row may stand for a family of achievements generated from content (one per chapter): its ID is a pattern (lepsu:chapter_cleared_<branch>_<n>), its title and description are parameterised, its count follows the content. A generated family is the one place the allusive guidance does not apply: a title assembled from the content's own branch and chapter number has to name them, and naming them is the point.

Catalogue table (functional contract)

Column	Content
ID	Stable identifier <namespace>:<name> (or an ID pattern for a family) — never changes once shipped (it is the key of the players' unlock records). Translation keys derive from it.
Title	Player-facing title (English master text).
Context	Translator note: the reference and the intent behind the title, one line.
Description	Player-facing description (English master text), self-sufficient for visible rows.
Category	Menu category key.
Scope	The window the fact is measured over: lifetime · single run · single day · single event · per level · per chapter · mechanic fact (one instant, a condition became true) · mechanic measure (one instant, a quantity reached a figure).
Criteria	The positive rule only, in plain words: what is counted, over the scope, with the exact threshold. No exclusions here.
Eligibility	Which runs / levels qualify: any area · campaign levels only · tier ≥ Hard · levels where the beam must be routed into the prism · levels with ≥ 3 solvers · … (the anti-farm and difficulty-floor lever). Never restates a Policies key; never excludes a level's authors.
Policies	Fixed triad, always complete, always written the same way: tainted: accept/refuse · granted: accept/refuse · retroactive: yes/no, or — where a row can only be recognised the next time the player finishes something — retroactive: on the next victory. Pre-solved runs are always refused for run-shaped rows (not a per-row choice). Mandatory for play-server rows too — the owning plugin is bound to apply them. Policies and Eligibility win over Criteria if they ever conflict.
Progress	The exact formula shown in the menu (unique puzzles won / 50) followed by the unit the bar names (in puzzles, minutes, blocks…), or —. State the unit whenever the number the player sees is not the number the description names — minutes under a sentence about hours, blocks under one about kilometres — and leave it out when the title already makes it obvious. Never shown once unlocked; never on a hidden row; never on a mechanic row; a row whose formula reads the lifetime totals the plugin has always kept is retroactive: yes, while one reading a tally begun with this release is retroactive: no — a bar is not itself a promise of a past; a hidden row whose reveal would turn into a grind has no formula.
Hidden	yes / no.
Prerequisite	ID of the parent, or —. Ordering and reveal only; never a gate, never a cascade; same owner.
Rarity	onboarding · common · rare · radiant.
Order	Integer, sort position inside the category (a family occupies one block).

Delivery table (project-facing)

Column	Content
ID	Join key with the catalogue table.
Owner	LE (Lasers-Enigma) or LEPSU (play server) — the single plugin that defines, evaluates and awards it.
Trigger	The discrete moment that evaluates it: victory · stats saved · join (retroactive) · owner event · component event · mechanic fact · mechanic measure.
Icon	Exact material name or head texture id.
Data needs	existing · derived (computable from existing tables, not a single counter) · new event · new counter · detector (a new observation in the laser/portal loop) · hard.
Wave	engine (ships with the #530 engine itself) · 1 (no new plumbing) · 2 (needs a new event / counter / detector) · 3 (later). The wave says when a row ships, not what it once needed: a row whose detector has since been written moves into the wave that carries it, and its Data needs cell keeps the record of what it cost.
Status	candidate · validated · shipped in vX.Y.Z · refused.
Notes	Free text: open questions, anti-farm rationale, known degenerate path. Not part of the implementable contract.

Invariants (stated once, never per row): everything registered counts in the total, hidden included; an earned achievement shows its unlock date, a recognised-from-history one shows unlocked from your history; a granted achievement is not visibly distinct from an earned one; "simultaneous players" always means simultaneous runs (a spectator or creative bystander never counts).

Catalogue

✅ marks an achievement that is built and shipping — and every row below now carries one. The catalogue is fully implemented across the two plugins, apart from the four rows named in Set aside, and why, which are not listed here. The Delivery table below records what each row cost to build.

✅ le:anniversary	LE	victory	Cake	existing (clock at victory in the player's time zone, and the date First Light was recorded)	1	validated	Implemented; ships with V11.1.0. Dates from when First Light was recorded, not from a victory that predates the achievement system — which is exactly why it cannot be recognised from a player's history.
✅ le:night_owl	LE	victory	Clock	existing (clock at victory, in the player's time zone)	engine	validated	Built-in, ships with #530's core sub-issue; tests hidden rows and the secret-achievement broadcast.
✅ le:beam_through_portal	LE	mechanic fact	Ender eye	detector (fact marked at the portal exit, once per crossing)	1	validated	Implemented; ships with V11.1.0.
✅ le:set_in_stone	LE	mechanic fact	White stained glass	detector (fact marked at the solidifier, while it holds any block)	1	validated	Implemented; ships with V11.1.0.
✅ le:senders_facing	LE	mechanic fact	Redstone torch	detector (fact marked at the sender being hit head-on)	1	validated	Implemented; ships with V11.1.0. Hidden: its title and description name a component the player meets late in the campaign.
✅ le:record_breaker	LE	victory	Diamond	existing (victory summary: a personal record beaten, tainted)	1	validated	Implemented; ships with V11.1.0. Reads the summary's new beat a personal record flag. Refuses a shared run, because such a run keeps no record to beat.
✅ le:attrition	LE	victory	Wither rose	existing (victory event: the puzzle's standing before and after the run)	1	validated	Implemented; ships with V11.1.0. Reads the area's distinct-solver and distinct-entrant counts, which the same release makes real — nb_players had always counted entrants. Difficulty measured as this server's players experience it, so no difficulty tier is needed and none goes stale on a small server.
✅ le:glassworks	LE	mechanic measure	Light blue stained glass	detector (measure reported at the solidifier: one block of glass per particle it is about to place)	1	validated	Implemented; ships with V11.1.0. First achievement about a magnitude rather than a condition: the figure lives in the registration, not in the enum, so retuning it after the beta costs one number and the descriptions naming it. Twenty-five is above one solidified beam's worth and is to be confirmed against a real level.
✅ le:first_mirror	LE	component event	Glass pane	new (the actor named on the existing mirror-placed event)	1	validated	Implemented; ships with V11.1.0. The actor travels through the placement animation task, so the event that says the mirror is in place also says whose it is. Read from that completion, never from the attempt.
✅ le:first_elevator	LE	component event	Piston	new (the cage announces its passengers where it already sweeps them)	1	validated	Implemented; ships with V11.1.0. The elevator names no Player anywhere, but it does hold every Entity inside its cage — sweeping them is how it carries them — so a passenger costs one instanceof in a loop that runs regardless. Announced once per ride, not once per block.
✅ le:emancipated	LE	component event	Iron bars	existing (the grid's walk-through event, plus its Death flag)	1	validated	Implemented; ships with V11.1.0. Read from the walk-through, which the grid fires before it takes the player's health — so the run is still live, the fairness check applies normally, and the notification reaches someone who can still read it. The design had assumed this row would need the ungated award path; checked against the code, it does not.
✅ le:first_rotation	LE	component event	Compass	new (the actor named on the existing rotation event)	1	validated	Implemented; ships with V11.1.0. Read from the after-event, never the attempt. The catalogue's title for this row was a verbatim song title, which the naming charter does not allow — renamed, and easy to overrule while it is unreleased. Its plumbing is the convention the other actor-dependent rows will follow.
✅ le:untouched	LE	victory	Snow block	new (per-puzzle tally: fresh starts asked for)	1	validated	Implemented; ships with V11.1.0. Read at the victory from what the puzzle's own tally holds — the restatement that made a second per-player lifetime unnecessary.
✅ le:percussive_maintenance	LE	stats saved	Stick	new (lifetime tally: fresh starts asked for)	1	validated	Implemented; ships with V11.1.0. Hidden and barless: a bar counting towards a secret is the secret, told badly. Judged at the next run boundary, since asking for a reset fires no evaluation of its own.
✅ le:frequent_flyer	LE	stats saved	Ender pearl	new (lifetime tally: portals come out of)	1	validated	Implemented; ships with V11.1.0. Crossings are buffered in memory and written in one statement when the player leaves the puzzle, so repeating one costs no extra write.
✅ le:own_worst_rival	LE	stats saved	Clock	new (lifetime tally: own records beaten)	1	validated	Implemented; ships with V11.1.0. The habit to le:record_breaker's first time; raised only on a solo run, since a shared one keeps no record.
✅ le:prism_split	LE	mechanic fact	Amethyst shard	detector (smoke fact at the prism site)	engine	validated	Built-in, ships with #530's mechanic-facts sub-issue; proves the mechanic-fact pipeline and the causal attribution.
✅ le:arrow_in_a_puzzle	LE	component event	Arrow	existing (Bukkit EntityShootBowEvent, filtered on the shooter standing inside an area)	1	validated	Implemented; ships with V11.1.0. Opens the Mishaps category. Hidden, because a joke read off a checklist is not one.
✅ le:firestarter	LE	mechanic fact	Flint and steel	detector (fact marked once at the burnable block, when it starts melting)	1	validated	Implemented; ships with V11.1.0. The only mechanic fact that lives in Mishaps: setting the scenery on fire solves nothing.
✅ le:no_second_chances	LE	victory	Golden carrot	existing (victory event: first entry, and the run's collected bonuses)	1	validated	Implemented; ships with V11.1.0. The strict form of le:clean_sheet: same sweep, but only the very first visit counts, so there is no second attempt and nothing to show progress on.
✅ le:stairway	LE	mechanic fact	Amethyst block	detector (fact marked at the solidifier when the frozen path gains height)	1	validated	Implemented; ships with V11.1.0. Height is compared with a small epsilon rather than exactly, since a beam's path is computed in floating point. Named for what it looks like — the catalogue's original title quoted a song, which the naming charter refuses.
✅ le:escape_velocity	LE	component event	Firework rocket	existing (AfterPlayerPortalTeleportEvent, reading the arriving speed)	1	validated	Implemented; ships with V11.1.0. The 1.2 blocks-per-tick threshold is reasoned from the code and is to be confirmed against a real level; it lives in the listener, so correcting it costs one number.
✅ le:cube_courier	LE	component event	Chest minecart	existing (AfterPlayerPortalTeleportEvent, plus whether the player is holding a cube)	1	validated	Implemented; ships with V11.1.0. Hangs off the same event as Escape Velocity, asking a different question of it.
✅ le:wrist_workout	LE	stats saved	Lever	new (lifetime tally: components turned)	1	validated	Implemented; ships with V11.1.0. Counted from the rotation after-event, which carries the actor, so a scheduled or synced turn credits nobody — and only while the actor has a live run in that puzzle, so a builder laying out a level does not fill in a chain about playing.
✅ le:wrist_workout_ii	LE	stats saved	Iron trapdoor	same tally	1	validated	Implemented; ships with V11.1.0.
✅ le:wrist_workout_iii	LE	stats saved	Netherite ingot	same tally	1	validated	Implemented; ships with V11.1.0. Two thousand turns is the catalogue's own figure, kept as the chain's top rung.
✅ le:gravity_fiddler	LE	stats saved	Slime ball	new (lifetime tally: sphere resizes)	1	validated	Implemented; ships with V11.1.0. There is no after-event for a resize, so it is read at MONITOR on the attempt: not cancelled, and the size actually different.
✅ le:butterfingers	LE	stats saved	Ender eye	new (lifetime tally: portals lost to a grid)	1	validated	Implemented; ships with V11.1.0. Counted on the grid's contact announcement, which is fired before anything is applied — the only moment the portals are still there to be counted.
✅ le:cube_overboard	LE	component event	Bucket	existing (PlayerWalkedThroughEmancipationGridEvent, plus whether the player is holding a cube)	1	validated	Implemented; ships with V11.1.0. Same moment as Butterfingers, asking a different question: the grid releases the held cube a moment later, so this is the last tick on which it is still in hand.
✅ le:sightseer	LE	area exit	Map	existing (area_player_stats: one row per puzzle entered)	1	validated	Implemented; ships with V11.1.0. Opens the new Explorer category. Counted by a single query when a run ends, not per rule and not on a timer, so it is right for a veteran without a new tally.
✅ le:scenic_route	LE	area exit	Leather boots	existing (the run's own step counter, published when the run ends)	1	validated	Implemented; ships with V11.1.0. Reads the new run-ended announcement, which fires for a win and for walking away alike.
✅ le:lost	LE	area exit	Compass	existing (area_player_stats: entries and victories in this puzzle)	1	validated	Implemented; ships with V11.1.0. Self-destroying condition handled by the ratchet: solving it later never takes the row back. The title is wry about the search, never about the player.
✅ le:stubborn	LE	area exit	Obsidian	existing (the run's own duration)	1	validated	Implemented; ships with V11.1.0.
✅ le:colour_theorist	LE	victory	Glass	derived (the area's component types, asked once per victory)	1	validated	Implemented; ships with V11.1.0. Needed a by-id lookup of a loaded area, which the area manager now offers; it walks the loaded areas rather than keeping an index, because an id is asked for at the pace somebody finishes a puzzle.
✅ le:clockwork	LE	component event	Repeater	existing (PlayerEnteredAreaEvent, plus the area's own components)	1	validated	Implemented; ships with V11.1.0. A level property, free to ask: the components are already in memory when the entry fires. The catalogue mentions a second scheduled-action row whose text never reached us; it is still unspecified.
✅ le:on_your_marks	LE	component event (race)	Golden boots	existing (AfterRaceGroupFinishedEvent)	1	validated	Implemented; ships with V11.1.0. Opens the new Race category. Awarded by UUID rather than to a player standing in a puzzle: a racer is teleported out the moment they finish.
✅ le:podium	LE	component event (race)	Iron ingot	existing (AfterRaceRunFinishedEvent + the persisted per-group results)	1	validated	Implemented; ships with V11.1.0. A race is scored per group and by total time, so placement only means anything once every group is in — which is why it waits for the run rather than the group.
✅ le:photo_finish	LE	component event (race)	Gold ingot	same	1	validated	Implemented; ships with V11.1.0.
✅ le:race_regular	LE	component event (race) + stats saved	Redstone torch	new (lifetime tally: race runs finished)	1	validated	Implemented; ships with V11.1.0. Awarded on the spot when the tally reaches three, with a rule that catches up at the next statistics write so a player who was offline still gets it.
✅ le:rtfm	LE	stats saved	Book	new (lifetime tally: info-item readings)	1	validated	Implemented; ships with V11.1.0. The info feature announces a reading rather than counting one, so it knows about neither the statistics nor the achievements. Counted only once the item has told the player something — pointing it at nothing is not reading the manual.
✅ le:hard_head	LE	stats saved	Iron helmet	new (lifetime tally: refusals)	1	validated	Implemented; ships with V11.1.0. Announced at the refusal itself, not at the message: the component_blocked_message option decides what the player reads, never whether the refusal happened.
✅ le:skeleton_key	LE	stats saved	Tripwire hook	existing (LockPlayerOpenEvent) + the lock's key chests	1	validated	Implemented; ships with V11.1.0. The catalogue asked for "all keys optional"; there is no optional key chest in the model, so the honest reading is a lock with no key chest at all.
✅ le:boomerang	LE	stats saved	Ender pearl	new (per-puzzle tally: command teleports)	1	validated	Implemented; ships with V11.1.0. Read from Bukkit's teleport event filtered on the COMMAND cause while a run is live, so the plugin's own teleports — reset, checkpoint, portal — are excluded by construction.
✅ le:boomerang_ii	LE	stats saved	Ender eye	same tally	1	validated	Implemented; ships with V11.1.0.
✅ le:boomerang_iii	LE	stats saved	Chorus fruit	same tally	1	validated	Implemented; ships with V11.1.0.
✅ le:switchboard	LE	mechanic fact	Lever	detector (the receiver's unlit → lit transition, already marked) + new lifetime tally	1	validated	Implemented; ships with V11.1.0. Reads a tally but is decided on the light rather than at the next statistics write, so the row arrives when the thing happens. The tally is raised by the statistics listener one event priority earlier, which is what lets the rule count the receiver that has just lit.
✅ le:switchboard_ii	LE	mechanic fact	Redstone lamp	same	1	validated	Implemented; ships with V11.1.0.
✅ le:switchboard_iii	LE	mechanic fact	Beacon	same	1	validated	Implemented; ships with V11.1.0.
✅ le:spectrum_master	LE	mechanic fact	Glass bottle	detector (three new facts: a receiver asking for yellow, magenta or cyan going from unlit to lit) + three lifetime tallies	1	validated	Implemented; ships with V11.1.0. Three facts rather than one so the bar can say which colours are still missing. Settles the catalogue's #39-vs-#93 overlap in favour of the lifetime reading; the single-run seven-colour row stays set aside with the rest of the per-component work.
✅ le:ouch	LE	component event	Blaze powder	new (PlayerBurntByLaserEvent, fired from the impact processor)	1	validated	Implemented; ships with V11.1.0. The episode is bounded by the fire itself — announced only when the player was not already alight — so standing in a beam is one burn rather than four hundred.
✅ le:well_done	LE	stats saved	Cooked beef	same event + new lifetime tally	1	validated	Implemented; ships with V11.1.0. The same event will carry the per-run "never hit" flag the companion plugin's dodge row needs.
✅ le:kaboom	LE	component event	Gunpowder	new (PlayerCaughtInBlastEvent, fired per player caught by the melt-down)	1	validated	Implemented; ships with V11.1.0. The blast already knew its victims — it damages them by name — so nothing had to be inferred.
✅ le:server_legend	LE	victory	Nether star	existing (the puzzle's standing before and after the run, already published on the victory)	1	validated	Implemented; ships with V11.1.0. Needed nothing new: the victory already publishes the records as a before/after pair, which is exactly the comparison.
✅ le:triple_crown	LE	victory	Golden apple	same, compared against the run's own duration, steps and actions	1	validated	Implemented; ships with V11.1.0. Holding the three is a fact about one instant, and the award is a ratchet: somebody beating one of them tomorrow never takes it back.
✅ le:chain_reaction	LE	mechanic fact	Fire charge	derived (the run's own history of ignition credits)	1	validated	Implemented; ships with V11.1.0. The fact nothing marks: three separate instants are not something one tick can see, so it is worked out on the run tracker and added to the credited set at the moment it becomes true. The queue never grows past three entries.
✅ le:cube_factory	LE	area exit	Iron block	new (per-run tally on the run tracker)	1	validated	Implemented; ships with V11.1.0. The service that makes a cube is handed a distributor, not a player; the button press is the only place that knows who asked, so that is where the run is credited.
✅ le:turn_it_off_and_on	LE	area exit	Redstone	existing (the per-puzzle reset tally) read as a difference since entry	1	validated	Implemented; ships with V11.1.0. A reset abandons the run and starts a fresh one, so a per-run counter could never see across it; the tallies now remember what they held the moment the player walked in, and "since you came in" is a subtraction.
✅ lepsu:efficient	LEPSU	victory (LEPSU @MONITOR)	Feather	existing (the run summary the engine publishes on the victory) + the room's published difficulty	1	validated	Implemented; ships with LEPSU V1.30.0. Opens the new Skill tab. The catalogue asked for a tier established over twenty distinct players; no such tier exists — what the model has is the builder's own figure — so the floor is the published tier, and a room sitting on the model's default earns nothing.
✅ lepsu:surgical	LEPSU	victory	Shears	same	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:speedrunner	LEPSU	victory	Sugar	same	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:blink	LEPSU	victory	Ender eye	same	1	validated	Implemented; ships with LEPSU V1.30.0. The catalogue wanted it hidden as trivially farmable; the difficulty floor is what stops that, so it is shown like its chain.
✅ lepsu:legendary_slayer	LEPSU	victory	Red concrete	existing (the room's published difficulty)	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:mythic_slayer	LEPSU	victory	Purple concrete	same	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ le:chest_raider	LE	component event	Chest	new counter (player_component_mark, keyed by component)	2	validated	Implemented; ships with V11.1.0. A mirror chest is a real chest and the plugin lets the right-click through, so the moment caught is Minecraft's own inventory opening; the block behind it says which chest it was. Keyed per component so opening one chest ten times counts once.
✅ le:mirror_mirror	LE	component event	Glass pane	new counter (per-run, keyed by component)	3	validated	Implemented; ships with V11.1.0. The run tracker now carries per-component tallies, bounded at 256 components per run so a wandering run cannot grow them without limit.
✅ le:full_spectrum_out	LE	component event	Prismarine crystals	existing event + the same per-run, per-component mask	3	validated	Implemented; ships with V11.1.0. ConcentratorColorChangeEvent names no player, so the area is asked who — if anyone — can be held responsible on exactly the terms the optical facts use. Earning it needs a level where three primary feeds into one concentrator can be switched independently; to be confirmed against a real level.
✅ le:full_spectrum_in	LE	component event	Beacon	new event (LaserReceiverInputColorChangeEvent) + the same mask	3	validated	Implemented; ships with V11.1.0. The receiver's per-tick task already built the set of colours arriving; it now merges it and announces the result only when it changes, so the added cost is one comparison. Same caveat as the row above: to be confirmed against a real level.
✅ le:pinball	LE	mechanic measure	Slime ball	detector (BEAM_REDIRECTIONS)	2	validated	Implemented; ships with V11.1.0. Read off the buffer the laser step already fills with the tick's derived particles, so there is no per-component site to forget or double-count. Figures to be confirmed against a real level. The description is an active imperative — Bend ten beams… — and not a state — Leave ten beams bent…: the figure is the level's, but the credit rule means only the player whose own move brought it about is awarded, and le:glassworks, the other mechanic measure, is phrased the same way. Raised twice in review and settled here, so it is not re-opened.
✅ le:pinball_ii	LE	mechanic measure	Magma cream	same	2	validated	Implemented; ships with V11.1.0.
✅ le:pinball_iii	LE	mechanic measure	Firework star	same	2	validated	Implemented; ships with V11.1.0.
✅ le:pinball_iv	LE	mechanic measure	Amethyst cluster	same	2	validated	Implemented; ships with V11.1.0.
✅ le:pinball_v	LE	mechanic measure	Nether star	same	2	validated	Implemented; ships with V11.1.0.
✅ le:light_year	LE	stats saved	Glowstone dust	new counter (beam_kilometres) + a per-run accumulator	2	validated	Implemented; ships with V11.1.0. Each tick, the number of particles alight is the number of half-blocks the light covered; it is credited to the single run whose own last action is the most recent, and to nobody while two runs have acted on the same tick. Nothing is counted in a level nobody is in. Figures to be confirmed against a real level.
✅ le:light_year_ii	LE	stats saved	Glowstone	same	2	validated	Implemented; ships with V11.1.0.
✅ le:light_year_iii	LE	stats saved	Sea lantern	same	2	validated	Implemented; ships with V11.1.0.
✅ le:marathon_solver	LE	victory	Clock	new counter (player_daily_victory)	2	validated	Implemented; ships with V11.1.0. One row per player, per day, per puzzle, so a puzzle replayed all afternoon counts once; the day is the server's own calendar, and rows older than today are swept away at start-up.
✅ lepsu:chapter_one_cleared	LEPSU	victory (LEPSU @MONITOR)	Paper	existing (the portal-tree progress snapshot)	1	validated	Implemented; ships with LEPSU V1.30.0. Re-asked in full at every victory rather than tracked, which is also what hands a player who finished the branch long ago everything they had earned, the next time they win anything.
✅ lepsu:solo_complete	LEPSU	victory	Written book	same	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:solo_perfect	LEPSU	victory	Nether star	same, plus the branch's bonus totals	1	validated	Implemented; ships with LEPSU V1.30.0.

✅ lepsu:community_champion	LEPSU	victory	Amethyst cluster	same	1	validated	Implemented; ships with LEPSU V1.30.0. The denominator is unbounded and grows, so it counts rather than showing a percentage.
✅ lepsu:two_heads	LEPSU	victory	Player head	existing (the run summary the engine publishes)	1	validated	Implemented; ships with LEPSU V1.30.0. Moved here from Lasers-Enigma: nothing in the engine ever cancels a taint, so on a server running the plugin alone the row could never be earned. Only a plugin that knows which levels are built for several players can own it.
✅ lepsu:chapter_one_perfected	LEPSU	victory	Gold ingot	existing (sumBonusesUnder / totalBonusesUnder)	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:apprentice_builder_solo	LEPSU	victory	Crafting table	existing (CreatorUnlockService)	1	validated	Implemented; ships with LEPSU V1.30.0. The promotion rule stops at the first branch that says yes, which is right for a role granted once and wrong for two rows, so the service gained a per-branch reading. The award ratchets where the rule does not.
✅ lepsu:apprentice_builder_duo	LEPSU	victory	Smithing table	same	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:partners_in_light	LEPSU	victory	Lantern	new counter (duo_partner_victory, owned by LEPSU)	3	validated	Implemented; ships with LEPSU V1.30.0. Nothing in the engine records who somebody played with, so this plugin keeps a per-visit note of who shared the level and a persisted counter per pair, written from both sides.
✅ lepsu:trio_trouble	LEPSU	victory	Campfire	existing (tag + the run summary)	1	validated	Implemented; ships with LEPSU V1.30.0.
✅ lepsu:mission_impossible	LEPSU	victory	Shield	existing event (PlayerBurntByLaserEvent) + a per-visit flag owned by LEPSU	2	validated	Implemented; ships with LEPSU V1.30.0. The engine announces a burn as it happens; what the row needs is whether one ever happened during the visit, so this plugin holds that flag itself rather than widening the engine's run summary.
✅ lepsu:chapter_cleared_<branch>_<n>	LEPSU	victory	Map	existing	1	validated	Implemented; ships with LEPSU V1.30.0. Generated from the portal tree at enable and re-checked on every PortalsUpdatedEvent, so a chapter built tomorrow gets its pair the moment it appears. Titles are parameterised on the branch and the chapter number.
✅ lepsu:chapter_perfected_<branch>_<n>	LEPSU	victory	Gold ingot	existing	1	validated	Implemented; ships with LEPSU V1.30.0.

Set aside, and why

Rows from the catalogue this wave did not build. The bar for setting one aside is narrow: a significant cost to the running server, or a complexity out of proportion to the row. Nothing else qualifies — in particular, not being able to measure something in game is a reason to ship the row with its figure marked to confirm, never a reason to leave the row unwritten, and neither is sequencing: a structure that has to be written first is work, not a refusal.

Row	Set aside because	What it would take
Déjà Vu (the same beam twice on the same mirror)	cost — the only row in the catalogue that adds per-particle bookkeeping to the loop that moves every beam of every active area. Its cost is the data structure, not the observation, so the "free when nobody asks" gate cannot cover it.	Its own project, with a measured budget on the beta server, and a configuration switch.
Gravity Well (beams bent by one sphere)	cost — counting how many beams a single sphere is bending is per-particle work in the same loop.	A detector shaped on purpose behind the observation gate, with its cost measured before it ships. The measure channel is ready for it.
Loop Wrangler (a self-sustaining laser loop) and Infinite Loop (a floor-to-ceiling portal momentum loop held for thirty seconds)	cost — neither loop has a detector, and neither detector is small: one has to notice the instant a beam path closes on itself, the other has to keep a per-area tick counter in the portal subsystem. Both are projects, not rows.	A detector each, budgeted and measured on the beta server before it ships, behind the observation gate so a server nobody asks pays nothing.

Several rows that appeared here in an earlier pass have since been written, and the reasons given for them did not meet the bar above. Chest Raider was set aside on a factual error — a mirror chest placed by a builder is a real chest, and a player opening it to take the mirrors is an ordinary act of play. Pinball was said to have no single place where a beam is bent; it has one, the buffer the laser step already fills with the tick's derived beams. Light Year and Marathon Solver were set aside for sequencing, which is not one of the two admissible reasons: an unmeasured figure ships marked to confirm, and a new persisted structure is work, not a refusal. Full Spectrum and Mirror, Mirror needed per-component identity within a run; that axis has now been built, bounded at 256 components per run.

Some shipped rows carry a figure that was reasoned from the code rather than measured in game: Glassworks (twenty-five blocks of glass at once), Escape Velocity (1.2 blocks per tick on the way out of a portal), the Bank Shot chain (ten to forty beams bent at once) and the Long Haul chain (a thousand to three hundred thousand kilometres). Each is noted in the delivery table as to be confirmed against a real level. Calibrating them is testing work, not a defect: the figure lives in the registration rather than in any enum, so correcting one costs a number and the descriptions that name it.
