chore(tools): delete the cliloc converter the Asset Bridge replaced (Phase 2)

`server/tools/cliloc-export/` existed for one reason: every modern UO client
ships its cliloc table in the Mythic container, and nothing in this stack could
read it — not the site, and not ServUO's own bundled `Ultima.StringList`. So an
operator installed UOFiddler, built this against its `Ultima.dll`, ran it over
their client and copied a 5 MB file to the web host, every time they patched.

Protocol 8 phase 2 put the decompressor in the shard plugin, where the client
files already are, and module-uo imports the table over the bridge. The tool has
nothing left to do. See docs/link/v8.md §9 and docs/website/CLILOCS.md.

Nothing in core referenced it — it was a standalone .NET console app under
`server/tools/`, and that directory is now empty.

+// a background tab has nobody to show a badge to — and refreshes the moment it
+// comes back, which is also the moment it would be most wrong.

+//
+// **This screen is the whole of the permission model beyond the role.** A module
+// declaring `uo.creature.spawn` is code the operator installed; it is not a
+// permission they granted. Enablement is the grant, and the cap is how much of
+// it — so this is the one screen in the feature where an operator decides what
+// the deployment *can do at all*, rather than what it is going to do tonight.
+//
+// **Nothing above `notify` and `inspect` arrives enabled.** Installing a module
+// must never start doing things, which is the posture a seeded engagement rule
+// already takes by arriving `enabled = 0`. The line falls between `inspect` and
+// `change` (org lead, 2026-09-03): an `inspect` action reads state and writes
+// nothing, so a deployment gains no risk by having it on, and `core.wait` — which
+// is `inspect` — arriving off would break every published event that waits.
+//
+// **A row with no stored setting is not "off".** It is "the default for its risk
+// class", computed on the server by the same function the runner asks. The screen
+// says which it is looking at, because "an admin turned this on" and "this has
+// always been on" are different facts and only one of them is a decision.
+//
+// **Admin only in both directions**, including the read: §K puts the switchboard

+// One run: where it is, what each of its steps did, what a human can still do
+// about it, and the diagnostic log underneath. Staff-wide to read; the six
+// controls are `admin` + `moderator`, and the server re-checks every one of them
+// against the run's live status — this screen predicts, it does not decide.
+//
+// **It polls rather than streaming.** A run changes on the runner's tick, which
+// is a fifteen-second clock, and a console watched for the length of an event is
+// a tab left open for two hours: an SSE channel for that is a connection held
+// per staff member for a screen that could not use the latency. The poll stops
+// the moment the run reaches a terminal status, because a completed run has
+// nothing further to say.
+//
+// **The parked step is the thing this screen exists to make impossible to
+// miss.** A run waiting on a GM cue is `running` and healthy-looking, and it will
+// stay that way for ever unless somebody presses confirm. It is called out above
+// the step list rather than being one row in it.
+//
+// **Phase 5 gave it a second one of those, and the panel is this phase's real
+// deliverable** (§ Observability): a phase whose steps have all finished and
+// whose advance condition has not been met is also `running` and also
+// healthy-looking. *"Why didn't phase 3 start?"* is answered here, above the
+// steps, in the condition builder's own words — and the sentence is the
+// SERVER'S. `gates[].where` arrives already rendered, because those labels are
+// defined in the condition grammar and a second renderer in the browser would
+// be a second opinion about what `gte` reads as.
+//
+// **Phase 8 gave it a third, and it is the one that outlives the event.** The
+// resource ledger is what this run changed in the world and what became of it,
+// and its unresolved rows are the reason a `completed` run can still need a
+// person — EVENTS.md §L: a run reaches `completed` with `cleanup_status =
+// 'incomplete'` rather than being held open, because a tidy `completed` row over
+// a shard full of orphaned monsters is the failure that would end this feature's

+// Two tables on one screen: the definitions an operator authors, and the runs
+// those definitions have produced. They are together rather than on two nav rows
+// because the question this screen exists to answer is one question — "what is
+// scheduled, and what is happening right now" — and the second half of it is the
+// one somebody opens at 8pm on a Friday.
+//
+// **The waiting badge is the whole reason the run table is here rather than
+// buried a click away.** A run parked on a GM cue looks perfectly healthy: it is
+// `running`, nothing has failed, and it will stay that way for ever because it
+// is waiting for a person who does not know they are being waited for. The count
+// comes from the run row itself (`waitingSteps`), so a run needs nobody to open
+// it before it can say so.
+//
+// **The calendar is a separate screen, not a third table here.** It answers
+// "when", this one answers "what" — and Phase 4, which built it, also made a
+// definition able to carry a recurrence, so the two questions stopped having the
+// same answer the moment an occurrence could exist before anybody pressed Start.

+// Admin → Events → Calendar (EVENTS.md §I, Phase 4).
+//
+// **This screen is the deliverable.** What this feature replaces is a WordPress
+// calendar plugin with no series field, no recurrence and no results — so a
+// month grid that knows about arcs, repeats and local time is not decoration
+// here, it is the point.
+//
+// **Two kinds of entry, drawn differently on purpose.** A solid one is a *run*:
+// a real row with a status, a pinned version and a console, and somebody can
+// cancel it. A dashed one is a *projection*: arithmetic past the runner's
+// fourteen-day horizon, with no row behind it, nothing committed and nothing to
+// open. An operator who treats a forecast as a booking has been misled by the
+// UI, not by the server, so the difference is drawn rather than merely stated —
+// and the legend says which is which.
+//
+// **The grid's date axis is the READER's zone; each entry's time is the
+// EVENT's.** §E gives the timezone to the event because every listing this
+// replaces is written in the shard's local zone, but "what is happening this
+// month" is a question about the month the person reading is living in. So the
+// cell an event lands in is the reader's date, and the time beside it always
+// carries the event's own zone — `20:00 Europe/Berlin` misreads as nothing.

+-- deliberate choice rather than a workaround for a missing unique index. Two
+-- accounts can no longer share an address, but a bounce arrives as an ADDRESS —
+-- it does not know which account was behind it, and it stays true after the
+-- account that held it changed its address or was deleted. Keying on the user
+-- would forget a dead mailbox the moment anybody moved.
+--
+-- `address_masked` is Phase 9's one addition to §4.5's DDL, and it exists because
+-- the hash-only table cannot be operated. An operator looking at a screen of
+-- sha256 digests cannot tell whether the list is three typos or a whole domain
+-- refusing mail, and un-suppressing somebody who fixed their mailbox is the one
+-- action this table has to support. `d***@example.com` is enough to act on and to
+-- see a domain-wide pattern in, and — the reason it is safe — the local part is
+-- destroyed rather than shortened, so the column is not an address book and

+-- is a fact about the recipient. Writing a suppression on every terminal failure

+-- role (§K layer 2).
+--
+-- **Not a grant table.** Nobody is named in it, because the role check already
+-- answered who; this table answers *what this deployment permits at all*, and
+-- how much of it per run. That is the distinction §K draws between a capability
+-- and permission to invoke it: a module declaring `uo.creature.spawn` is code the
+-- operator installed, not a permission they granted.
+--
+-- **A missing row is not "disabled" — it is "the default for its risk class".**
+-- Rows are written when an admin changes something, never seeded at boot, for a
+-- reason that is structural rather than tidy: the registry is assembled in
+-- `registerCore()` and by module `register()`, both of which run under
+-- `routeManifest.js` and `swagger.js` against a DEAD POOL (MODULE_API.md §2.2).
+-- A boot-time seed from the registry would be exactly the database write those
+-- two forbid. Reading a default from the risk class costs one branch and means a
+-- deployment that never opens this screen behaves correctly.
+--
+-- The row survives its action: uninstalling a module leaves the settings behind,
+-- so re-installing it restores the caps the operator chose rather than silently
+-- resetting them. The switchboard only lists what is registered *now*, so a
+-- stranded row is invisible until its action comes back.

+-- The cleanup ledger: everything one run created or leased, and what became of

+--
+-- **It holds both kinds of thing an event owns.** An OBJECT it created is
+-- `kind: 'creature'` with `ref` a serial, reverted by its own action's
+-- `revert()`. A VALUE it leased is `kind: 'override'` with `ref` the lease id and
+-- `payload` carrying the baseline and what was applied, restored by the lease's
+-- own `restore()`. One table, because cleanup asks both the same question --
+-- what is still out there, and did putting it back work.
+--
+-- **Rule 1: a resource is recorded BEFORE it is confirmed.** A spawn's serial
+-- does not exist until the module answers, so what is written before the dispatch
+-- is a PLACEHOLDER keyed by the step's idempotency key (`kind` = the reserved
+-- '@step', `ref` = that key). On the answer the reported resources are inserted
+-- `confirmed` and the placeholder is resolved. If the acknowledgement is lost the
+-- placeholder survives, and cleanup calls `revert()` with the idempotency key and
+-- no resources -- which is why §F's `revert({ runId, resources, idempotencyKey })`
+-- takes the key at all. Recording afterwards instead would make every object
+-- whose ack was lost invisible to cleanup for ever.
+--
+-- **Rule 2: revert is idempotent, and its failure is loud and sticky.** A row
+-- that never reverts stays visible -- the run reaches `completed` with
+-- `cleanup_status = 'incomplete'` rather than being held `running`, because a
+-- tidy `completed` over a shard full of orphaned monsters is the failure that
+-- would end this feature's credibility on its first bad night.
+--
+-- **The unique key is what stops two events leasing one target**, and it must
+-- hold among LIVE rows only: last week's finished event must not keep this
+-- week's from leasing the same rate. MariaDB has no partial index, so the
+-- encoding is a STORED generated column that is NULL once the row is no longer
+-- ours -- and multiple NULLs do not collide in a unique index. It is derived from
+-- `status` ALONE and the opaque columns stay in the KEY, which is the shape
+-- TEAMS.md §2.5 had to be corrected into: MariaDB refuses ON DELETE SET NULL on a
+-- foreign key whose column is a base column of a stored generated column
+-- (error 1901), so `step_id` must not appear in the expression.
+--
+-- **The key is held by the three statuses that mean "core still believes this is
+-- ours"** -- `pending`, `confirmed`, `reverting` -- and released by the three that
+-- mean it is not. §D says "among non-reverted rows", which was written before the
+-- six statuses had their meanings; taken literally it makes `drifted` and
+-- `orphaned` hold a target for ever, so one bad night would disable a lease
+-- permanently with no control able to clear it. `drifted` means somebody else has
+-- hold of the value and this run has deliberately let go of it; `orphaned` means
+-- it vanished. Neither is a claim on the target, and both stay LOUD by another
+-- mechanism -- `cleanup_status = 'incomplete'` and a row on the run console --

+// ── Core's own event actions ───────────────────────────────────────────────
+//
+// EVENTS.md §F, and Phase 1 of EVENTS_PLAN.md. The twin of config/coreTriggers.js
+// and registered through the same staging area a module will use in Phase 7 —
+// which is the entire reason these three exist this early. A registry whose first
+// real registrant is a module is a registry that has already drifted, and §F's
+// claim that core is "an event engine that can announce, wait, cue a human and
+// publish results" with NO module installed is only true if core declares the
+// verbs that do it.
+//
+// **Three actions, and between them they cover the three things an event can do
+// that name no game noun at all**: tell people something, let time pass, and ask
+// a human to go and do something. A deployment with no game module installed has
+// a working event system made of exactly these.
+//
+// **Phase 8 added a fourth, and it is the odd one out on purpose.** `core.lease`
+// names no game noun either — it borrows a value some module declared — but
+// unlike the other three it genuinely changes the world, so it is `risk: 'change'`
+// and therefore default-off, admin-only and cap-checked like any module verb.
+// It is CORE's rather than each module's because §F puts the duration bound and
+// the two-events-one-target conflict check on core's side of the seam: a lease
+// verb per module would be that bound re-implemented once per module, advisory
+// everywhere, and wrong in the first one that forgot it.
+//
+// **Phase 10 added the last two, and they are the integrations** (EVENTS.md
+// §J). `core.announce.post` sends an ARTICLE rather than a line — it links a
+// post an editor already wrote and queues it through `announce_jobs`, so the
+// town crier and Discord arrive as already-registered legs with their retry and
+// their classification rather than as a second delivery pipeline. And
+// `core.results.publish` is what makes §F's "publish results" literal: it ranks
+// the run's participants and stamps the table published. Both name a game noun
+// nowhere, which is why they are core's; six actions is now the whole of what an
+// event can do on a deployment with no game module installed at all.
+//
+// **Phase 2 gave all three real bodies**, and between them they exercise every
+// shape §F's envelope can take: `core.announce` does work and finishes,
+// `core.wait` finishes while deferring what follows it, and `core.cue` succeeds
+// without finishing at all. The runner learns nothing about any of them by id —
+// each says what it needs in the envelope, through the same two members Phase 7
+// hands to a module.
+//
+// **This file must not touch the database.** It is required from `registerCore()`,
+// which runs under `routeManifest.js` and `swagger.js` against a dead pool
+// (MODULE_API.md §2.2). Nothing below runs at require time; the announce leg is
+// looked up inside `perform()`, per call, which is also what makes a leg
+// registered by a module that booted later reachable at all. `core.lease` is the
+// one action here that reaches a table, and it requires the model INSIDE
+// `perform()` for the same reason — a top-level require would make this file
+// build a pool during route-manifest generation.

+//
+// ENGAGEMENT.md Phase 6, decision 3. Before this phase the Team pipeline mailed
+// people with no operator configuration at all: the code decided who was mailed
+// and about what, and the only knobs were per-user. Phase 6 moves that decision
+// onto rules — which default `enabled = 0`, and of which core seeds none.
+//
+// **So a straight migration would have stopped Team email on every existing
+// deployment, silently.** The org lead's decision was to honour the invariant
+// rather than carve an exception into it: the rules are seeded, and they are
+// seeded OFF. Team email resumes when an operator opens Admin → Engagement →
+// Rules and switches one on, and until then the admin screen says so in as many
+// words (`EngagementRules.jsx`). The release note names it.
+//
+// The alternative — seeding them enabled so nothing changes for anybody — was
+// considered and refused. "Nothing is seeded, nothing is on by default" is what
+// makes a rules table safe to restore, import or replicate, and an exception
+// carved for the one pipeline that predates the engine is an exception that has
+// to be re-argued every time somebody reads the invariant.
+//
+// **Seeded once, not ensured on every boot**, and the difference matters: an
+// operator who deletes a rule must not find it back after a restart. The guard is
+// a settings key, the same mechanism a one-shot migration uses, so a deployment
+// that has seen this seed never sees it again — deleted rules stay deleted, and
+// an enabled rule stays enabled rather than being reset to off.
+
+// **Phase 11 added a fifth, for `news.post`, and it needed its OWN one-shot key
+// rather than an entry in the list above.** The Team key is already stamped on
+// every deployment that has booted since Phase 6, and the guard reads its
+// presence — so appending to `RULES` would have seeded the news rule on fresh
+// installs only, and on exactly the upgrades that need it, never. Those are the
+// deployments where `pushDispatch.publish('news.post', …)` used to run and no
+// longer does (§7.1 Q9): they would have lost news push with no rule to switch
+// on and no way to tell why. One key per seed GROUP is the rule this establishes;
+// a sixth rule for a new trigger takes a sixth key, and a rule added to an
+// existing group is a rule that only fresh installs will ever see.

+//   provider returns no opinion and the stream-level preference decides.

+// ENGAGEMENT.md Phase 7. The third channel to get behaviour, and the one whose
+// "address" is not an address at all: the destination is the user's own row in
+// this deployment's own table. `addressFor` still exists and still answers null,
+// because the question it asks — *can this channel reach this user right now* —
+// has a real answer here, and it is the same answer email's has: not if the
+// account is no longer active. An outbox row can sit through a `delay_seconds`
+// grace window, so a user banned between the emit and the send is exactly the
+// case this catches.
+//
+// **What makes it different from email is what it does NOT have to do.** There
+// is no transport, no relay to classify a failure for us, no unsubscribe link to
+// mint per recipient, and no address to hash — an inbox item is addressed to a
+// user id, and `engagement_sends.address_hash` exists to correlate a bounce that
+// this channel cannot have. So `deliver` is two steps: render the template into
+// the three columns, and insert.
+//
+// **It never throws**, for the reason `emailChannel` states: the worker reads a
+// throw as a transient failure and retries five times, so an unrenderable
+// template would become five identical failures in the send log instead of one
+// honest terminal row.
+//
+// **A duplicate `dedupe_key` reports success.** The acceptance line calls it a
+// no-op; from the recipient's side it is a delivery — they have the item — and

+// ── Seeding what a module ships (ENGAGEMENT.md Phase 11b, decision 7) ──────
+//
+// Core's own bodies and rules are seeded from `seedDefaults()`, and a module's
+// cannot be: `server.js` calls `seedDefaults()` BEFORE it requires `app.js`, and
+// requiring `app.js` is what scans the volume and runs the loader. At the moment
+// core seeds, no module has registered anything at all.
+//
+// So this runs from `modules/lifecycle.js` `boot()` instead — after the
+// `installed_modules` reconcile, so a module the operator disabled or one that
+// failed to load is skipped rather than seeded, and BEFORE the `onBoot`
+// dispatch, so a module that warms a cache in `onBoot` may assume its rules
+// exist.
+//
+// **It reuses core's two seeders rather than reimplementing them**, which is the
+// whole argument for the registry existing (decision 7): `seedOne` owns the
+// `customized` skip and the `seed_version` comparison, `validateEmailBlocks`
+// owns what a renderable body is, and a module supplies data. A copy of either
+// living outside this directory would drift the first time core improved the
+// original — and the drift would surface as a mail somebody already received.
+//
+// ── The asymmetry, once more, because it is the thing to get right ─────────
+//
+// **Templates are re-ensured every boot.** A row carries `seed_key`,
+// `seed_version` and `customized`, so re-ensuring is how a better default
+// reaches a deployment without stealing an operator's edit (§4.6.1 property 3),
+// and a template added in a later module version reaches every deployment rather
+// than only fresh ones.
+//
+// **Rule groups are one-shot, each under its own settings guard.** Re-ensuring a
+// rule would resurrect one an operator deleted and reset one they enabled. This
+// is 11a's seed-key finding as a mechanism: a rule appended to an existing group
+// reaches fresh installs only, and a rule that must reach already-stamped
+// deployments takes a new group key. The module chooses; this file honours it.
+//
+// **Never throws.** It is on the boot path beside every other `safe()`-wrapped

+//
+// ENGAGEMENT.md §4.6.1 property 1, implemented in Phase 6. The property is that
+// **a new trigger renders through `notify.event` with no authoring at all** —
+// "add a trigger" must not mean "and now write a template". Nothing implemented
+// it before this phase, and building the email channel is what made the hole
+// visible: a trigger payload is domain-named (`teamName`, `threadTitle`,
+// `postUrl`) while the generic seeds are structural (`title`, `intro`, `items`,
+// `actionUrl`). The two vocabularies never met.
+//
+// **The rule, settled by the org lead 2026-08-29: the payload wins, and the
+// projection fills gaps.** A name the payload already carries is left exactly as
+// emitted — `news.post` and `team.announcement` both declare their own `title`,
+// and a projection that overwrote it would replace a real headline with a
+// category label. Only a name the payload does NOT define is supplied here.
+//
+// **What it is careful not to do is guess at domain meaning.** There is no table
+// mapping `threadTitle` onto `title`, and there will not be one: every such
+// mapping is a piece of one game's vocabulary compiled into core, and it is wrong
+// the first time a module names the same thing differently. The three fallbacks
+// below are all derived from the DECLARATION — a trigger's own label, its own
+// description, its own first declared url — which every trigger has by
+// construction because `registerEventTriggers` refuses one without them.
+//
+// The consequence, stated plainly: an unauthored mail for `team.forum.post` is
+// titled "Team — new forum post" rather than the thread's title. That is a plain
+// mail, not a wrong one, and the operator's answer is the bespoke template that

+// keyed (user, Team) and is the preference people actually hold today — someone
+// in six Teams silences one. Migrating the second into the first would mean a

+// without core's engine learning what a Team is.

+// A registrant claims a scope PREFIX — the part of a scope key before the colon,
+// `team` in `team:12` — and answers, for a set of users and one channel, what
+// that scope says their mode is.
+//
+// **Where a scope answers, its answer REPLACES the stream-level preference; it
+// does not intersect with it.** The decision was phrased as "a suppression below
+// the channel preference", and building it showed that reading is the one that
+// cannot ship: `notification_channel_prefs` holds a row only where a user has
+// expressed something, absence means the channel's `defaultMode`, and email's is

+// ── The whole authorisation decision, behind one function ──────────────────
+//
+// EVENTS.md §K, and Phase 6 of EVENTS_PLAN.md. Four layers stand between an
+// action being *declared* and an action being *carried out* — role, enablement,
+// cap, and the shard's own switch — and §K asks for them in one place rather
+// than spread across route middleware:
+//
+//   > **Keep the check in one function.** Not for tidiness: it is what makes an
+//   > EM-style delegation model a *later* option rather than a redesign. If a
+//   > deployment ever wants named coordinators with their own budgets, that is
+//   > one function learning to consult a second table, and nothing else in this
+//   > document changes.
+//
+// So `mayInvoke()` below is the only thing in this codebase that answers "may
+// this happen". The router still calls `requireRole` — that gate is about
+// reaching the ROUTE — but whether a particular verb may be aimed at the world is
+// decided here, once, on every path that can cause it: authoring a step,
+// publishing, the dry run, starting a run, and the runner's own unattended
+// dispatch.
+//
+// ## Four layers, and where each one is actually enforced
+//
+// 1. **Declaration** — a module says a verb exists. Not a permission, and not
+//    checked here: `dispatch.js` already answers a step whose action nobody
+//    registers, and it answers it `dormant` rather than `refused`, because an
+//    uninstalled module is a different fact from a forbidden one.
+// 2. **Role** — `change` and `irreversible` are `admin` only. See below.
+// 3. **Enablement and caps** — this file, against `event_action_settings` and
+//    `event_run_budget`.
+// 4. **The shard's own switches** — `AdminWriteEnabled` and `AdminAccessFloor`
+//    live on the shard host, outside the website's reach entirely, and core
+//    deliberately does not duplicate them. A module honours them when it
+//    translates an action into a sidecar command (P9); a second copy of that
+//    decision in core would be a copy that could disagree with the shard about
+//    whether the shard is accepting writes. It is named as a layer because
+//    leaving it unnamed is how it comes to be re-implemented.
+//
+// ## The role line, and why it is drawn at `change`
+//
+// §K's table says "any step whose action is above `notify`, and the action
+// switchboard — `admin` only". Read literally that is the same sentence that made
+// `core.wait` — `risk: 'inspect'` — ship disabled by default, and the org lead
+// settled that on 2026-09-03: the line falls between `inspect` and `change`, not
+// between `notify` and `inspect`. An `inspect` action reads state and writes
+// nothing, so neither the default nor the role floor gains a deployment anything
+// by excluding it, and an editor who cannot author a step that WAITS has an
+// authoring role that cannot author.
+//
+// ## Why `user` may be null, and what that means
+//
+// The runner dispatches with nobody logged in. It is not "the system escalating":
+// the role was checked when a human published the version and again when a human
+// or the scheduler started the run, and **a run already in flight is not re-gated
+// against its starter's current role**. Re-checking would mean that demoting an
+// admin at midnight silently strands every event they started — an event stopping
+// halfway through because of an unrelated personnel change. §K's "a demoted user
+// loses access at once" is about reaching a route, and it still holds exactly
+// there. Cancel is the control for a run that should stop.
+//
+// ## Why the cap check can spend
+//
+// `mayInvoke` reads on every path but ONE, and on that one it must also write.
+// The cap is held by a conditional `UPDATE` whose WHERE carries the guard (§E), so
+// checking and then spending would be two statements with a race between them —
+// the exact race the conditional increment exists to remove. `spend: true` is
+// therefore a parameter rather than a separate function: one decision procedure,
+// one set of layers, and the authoritative check is the one that also commits.

+// this is the undo half, plus the reconcile that answers "is any of it still
+// there?" after something outside core restarted.
+//
+// **Cleanup is derived from the ledger, never authored.** An operator cannot be

+// action. There is one function, it reads rows, and it runs on EVERY terminal
+// path: completion, cancellation and abort alike.
+//
+// **It is not built out of `event_run_steps` rows** (org lead, 2026-09-03). The
+// plan's phrase is "cleanup steps are generated from the ledger", and the
+// tempting reading is a synthetic phase of real step rows so the console's
+// per-step retry comes free. It is the wrong shape here for one concrete reason:
+// `event_run_resources` already carries `revert_attempts` and `last_error`, so
+// synthetic steps would put a second retry counter beside the first and the two
+// would disagree the first time a step reverted three of its four resources.
+// The manual retry the API surface promises is a route over the ledger —
+// `POST /admin/events/runs/:runId/cleanup` — rather than a step control.
+//
+// **Where it runs from.** One place: the runner's cleanup leg, which finds
+// terminal runs that still owe the world something and works their rows. Hooking
+// each terminal path instead would be four call sites, three of which are inside
+// a request, and none of which would survive the process dying mid-cleanup. The
+// leg is ordered AFTER advance in the tick, so a run that completes in one tick
+// is cleaned in the same one.
+//
+// **The scan's WHERE clause cost two live-walk findings, in opposite
+// directions.** A run whose only resource was a LEASE never went through
+// `ledger.markRunDirty` — `core.lease` reserves its own row — so its
+// `cleanup_status` stayed `not_required` and the lease was never given back at
+// all. And a run whose first sweep failed was moved to `incomplete` by that very
+// sweep, so it was never picked up again: `MAX_REVERT_ATTEMPTS` meant ONE attempt
+// rather than three. The first is why `not_required` is in the scan; the second
+// is why `incomplete` is written HERE only once nothing retryable is left.
+//
+// **Rule 2 is what the bounds are for.** A revert that never succeeds must stay
+// visible rather than cycle: `MAX_REVERT_ATTEMPTS` stops the automatic retry, the
+// run reaches `completed` with `cleanup_status = 'incomplete'`, and the rows stay
+// on the console with their last error. Only a human's cleanup clears the

+// was recorded as `done` is a world change nothing will ever come back for.

+// **The timeout is the module contract's, not this file's opinion.** Every action

+// ── Phase advance gates: the emit-path observer, and the words for the panel ─

+// EVENTS.md §E and § Observability, and Phase 5 of EVENTS_PLAN.md. Two things
+// live here because they are two halves of one claim — that an operator can
+// answer *"why didn't phase 3 start?"* without reading a server log:
+//
+//   `observe(event)`  — the trigger stream's other subscriber. Beside
+//                       `engine.dispatch`, on the same seam, with the same
+//                       fire-and-forget posture.
+//   `describe(gate)`  — the same gate rendered in the condition builder's own
+//                       words, which is what the diagnosis panel shows.
+//
+// **Why the counting happens here and not on the runner's tick.** A gate that
+// waits for three boss spawns is counting things that happen *between* ticks. A
+// poller cannot count them: fifteen seconds after the third spawn there is
+// nothing left to observe, and a tally kept in a process's memory is a tally a
+// restart silently sets back to zero — with the phase then waiting for three
+// more of something that already happened. So the emit path writes, and the tick
+// reads. That division is the whole design of this file.
+//
+// **The cost of that, and its bound.** Every game event of every trigger some
+// run is waiting on costs one indexed lookup, and the common answer is zero
+// rows. Only when a gate is open does anything else happen, and then it is one
+// UPDATE per open gate — bounded by how many runs can be waiting on one trigger
+// at once, which is bounded by how many runs exist.
+//
+// **The words are rendered here, on the server, not in the client.** The panel's
+// entire value is that it reads the way the condition builder reads — `gte` as
+// *"is at least"*, `present` as *"is present"* — and those labels are defined in
+// `engagement/conditions.js`. A renderer in the browser would be a second
+// implementation of a grammar the server owns, and the first operator to meet a

+//
+// **Rule 1 is the whole reason this file is not two lines inside `drainStep`.**
+// A resource is recorded BEFORE it is confirmed. The obstacle is that a spawn's
+// serial does not exist until the module answers, so there is nothing to write a
+// row about yet — which is why what goes in before the dispatch is a PLACEHOLDER
+// keyed by the step's idempotency key rather than by the object:
+//
+//     pre-dispatch   INSERT pending { kind: '@step', ref: <idempotency key> }
+//     answer         INSERT confirmed { kind: 'creature', ref: '0x40001234' } × n
+//                    resolve the placeholder
+//     ack lost       the placeholder is still `pending`

+// answering it exact. Until then the contract is still honest, because §L
+// requires reverting something that does not exist to be a SUCCESS.
+//
+// **Recording is idempotent, and the database is what makes it so.** A retry
+// re-dispatches the same idempotency key, and a module that answers with the same

+// action answers `{ ok: true, participants: [...] }` and the runner writes them
+// beside the resources, on the same two success shapes, through the same
+// classify → record path. There is no `ctx.events.participants` API and no route:
+// a second write path into a run core is mid-tick on would be a second thing that
+// can race the claim, for a caller that does not exist until a module can source
+// the data at all (Phase 11's plugin-side participation ledger; Phase 12's
+// collect step is the first consumer).
+//
+// **Core cannot source a participant and does not try.** §J: `member_key` is
+// module-opaque, `user_id` is filled in by whoever knows the link table. For
+// module-uo that is `shard_links`; for another game it is something else, and a
+// core that guessed would be one game's identity model compiled into core. So a

+// ── The live cap meter ─────────────────────────────────────────────────────
+//
+// EVENTS.md §I, Phase 13: the step editor's "live cap meter". What would this
+// plan spend, and what does this deployment allow?
+//
+// **It is not the dry run, and the difference is the whole reason it exists.**
+// `verify.js` dispatches every step with `verify: true` — through the module,
+// and through the module to a sidecar and a game tick — and a pass against a
+// published version is RECORDED, because that record is what §K's gate reads
+// before letting a schedule start something unattended. Both of those are right
+// for an act an author performs once, deliberately, when the plan is finished.
+// Neither is right for a number that has to move while somebody types: a meter
+// on the dry run's path would put a shard round trip behind every keystroke and
+// would stamp `verified_at` from a form still being edited.
+//
+// So this file answers the half of the question core can answer ON ITS OWN:
+// `cost()` is a pure function of params (§F), and the caps come from the
+// switchboard. Nothing is dispatched, nothing is written, and no definition need
+// exist — the body is the spec in the author's hands, saved or not.
+//
+// **What it therefore cannot tell you** is everything the module knows: whether
+// the landmark exists, whether the creature is on the allowlist, whether the
+// shard is reachable. That is the dry run's, and the meter must not read as a
+// substitute for it — which is why the editor keeps both and labels them apart.
+//
+// ## Why the per-phase subtotal is here rather than computed in the browser
+//
+// §I asks the timeline for "its cap draw" per phase, and the arithmetic is
+// trivial — but the *inputs* are not in the browser. `cost()` runs on the server
+// and only on the server; a client that summed anything would first have to be

+// **Why there is no library here.** The server's dependency tree has no date
+// library at all — no luxon, no date-fns, no tz package (check `package.json`
+// before adding one). What it does have is Node's own full tzdata behind

+// (which `Intl` does exactly) and invert that mapping by search. Everything
+// below is that one idea.
+//
+// **Why not cron.** Decided in §E and restated in the plan: there is no parser
+// in the tree, the only precedent is in the bot (another process), and a cron
+// string is the one field an operator cannot proofread. Four closed shapes

+// `event_definitions`' working copy and in `event_versions.spec`, and this file
+// is the only thing that decides whether one is well formed.
+//
+// **Every check here is a boundary, not a convenience.** The authoring UI (Phase
+// 3, then Phase 13) will re-implement some of them for the sake of a good

+// **What this file knows, and what it deliberately refuses.** Two top-level keys

+// than preserved: a spec that silently carries `announcements` today is a spec
+// whose author believes announcements work, and the later phase that gives the
+// key meaning would inherit a corpus of unvalidated ones. The refusal list is the
+// changelog — Phase 4 added the recurrence shapes, Phase 5 added a phase's
+// `advance`, Phase 10 adds `announcements`.
+//
+// **Phase 4 widened `schedule` from one shape to four** — `manual`, `once`,
+// `weekly`, `monthly` — and every check on them is a check on SHAPE. The
+// arithmetic they describe lives in `events/recurrence.js`, and the zone they are
+// computed in is `event_definitions.timezone`, a sibling column this file cannot

+//    published that names a verb nobody can perform.

+// Every other reader of these tables is staff, and every field they are shown is
+// one somebody with a role was allowed to see. What comes out of here is read by

+// The day somebody adds a column to `event_runs` — a claim token, an operator's
+// note, a last error — a `{ ...run }` anywhere here would publish it, silently,
+// in the release after the one anybody reviewed.
+//
+// Three things are absent from every shape below, and each is a decision:
+//
+//   • **The spec.** Phases, steps, actions and their params are the plan for
+//     changing a live world. A visitor is told what is happening and when, and
+//     the LABEL of the phase while it is happening; the steps are the operator's.
+//   • **Health, cleanup, claims and errors.** A degraded run is a fact about the
+//     deployment's plumbing. "The event is running" is the fact about the event.
+//   • **`member_key`.** It is the game's own identifier for a character, it is
+//     module-opaque, and core cannot say what it discloses — so it stays unsent
+//     even on a results table where every other column is published.
+//
+// **What makes something public is `listed` AND `ready` AND not a rehearsal**,
+// and all three live in SQL (`eventDefinitions.db.getPublicBySlug`, and

+//
+// **`cleanup` is the eighth, and Phase 8 is what gave it a ledger to work over.**
+// It re-runs the teardown across every resource a run has not given back, and it

+ * process died is reclaimed once the lease lapses — that reclaim is the whole
+ * reason §E's CAS survives §N4's single instance. A `reverting` row had no such
+ * bound and nothing released it, so a process killed mid-teardown stranded the row
+ * for good: the sweep skipped it every 15s forever, `cleanup_status` never left
+ * `pending`, and `POST …/cleanup` — the recourse §I names — answered 200 and did
+ * nothing, because it claims through this same function. Observed with a lease,
+ * which then blocked the NEXT run of the same event from taking the value.
+ *
+ * The stale test is `updated_at`, not a new column: the row is stamped exactly
+ * when it enters `reverting` and is not written again until the revert resolves,
+ * so for a `reverting` row `updated_at` IS "when this claim was taken". The bound
+ * is the run lease's, for the run lease's reason — it has to outlast a whole
+ * tick's work on one run, and every revert in a sweep is bounded by its action's
+ * own `budgetMs` long before this.
+ *
+ * `revert_attempts` is deliberately NOT incremented by reclaiming. A stale claim
+ * is a process that died, not an attempt that failed, and counting it would burn
+ * the retry budget on crashes — Engagement Phase 14's rule, one table over.
+ *
+ * **`updated_at` is re-stamped explicitly, and that is what keeps this a CAS.**
+ * This connector sends `CLIENT_FOUND_ROWS`, so `affectedRows` counts rows MATCHED
+ * rather than changed. For the four fresh statuses that is harmless — the winner
+ * moves the row to `reverting` and the loser's `status IN (…)` no longer matches.
+ * A stale `reverting` row has no such natural change: without re-stamping, the
+ * row would still satisfy `status = 'reverting' AND updated_at < …` and a second
+ * claimer would match it too. Writing the column is what makes the second one

+// EVENTS.md §D and §I. "Royal Spy Mission → Risky Partner → Message From the
+// Void" is continuity that exists nowhere in the tooling this feature replaces
+// (§ "What the real calendar shows, and what it is missing": *no series or
+// recurrence field*). One small table buys it, and this is the policy half.
+//
+// **Why the writes are `admin, editor` and not `admin`.** A series is authoring,
+// and it is the same act as writing the definition that goes in it — §N2's
+// narrow gate is about *committing the deployment to a run* (publish, start),
+// which naming an arc does not do. An editor who can write the events but not
+// the arc they belong to would have to ask an admin to type a title.
+//
+// **A slug is derived once and then frozen**, exactly as a definition's is: the
+// public arc page lives at `/events/series/:slug` (Phase 14), and a slug that
+// moved would break every link to it. Renaming the series is free.
