v0.2.0 — generic Foundry hook facade (rip-and-replace of v0.1.0)

v0.1.0 shipped as a curated-event catalog (18 hand-written handlers
+ system adapters + an encounter.js stub). Wrong shape. v0.2.0 is a
RIP-AND-REPLACE per HOOK_CONTRACT.md (docs/HOOK_CONTRACT.md):
generic Foundry hook facade with NO domain interpretation.

## What's new

scripts/internal/ — new modular structure:
- registered-hooks.js: the §6 hook set (~60 raw Foundry hooks,
  envelope name, sync/async mode)
- envelope.js: buildEnvelope + sync/async dispatch (§8)
- subscribers.js: subscribe/subscribeMany/subscribeAll/unsubscribeAll
  primitives (§3) + error containment (§3.5)
- adapter-registry.js: registerSystemAdapter + semver-range matching
  (§5) + ready-time evaluation
- semver.js: inline semver matcher (no external dep)
- anti-corruption.js: hook rename normalization (§9) + arg shape
  fixes (§10) + combatInactive synthesis from updateCombat
- lifecycle.js: init/ready/unregisterModule hooks (§4)

scripts/main.js — Foundry entry point. Registers the public API on
mod.api; init installs Foundry hooks; ready evaluates adapters;
unregisterModule cleans up.

## Tests

- tests/verify-hooks-lib.mjs — 554 assertions in 0.34s (under the
  2s budget). Sections A-G of tests/PLAN.md:
  - A: envelope shape (every registered hook produces exactly
    {ts, hook, args})
  - B: subscriber API (single, batch, all, atomic, error path)
  - C: error containment (throwing consumer doesn't break chain)
  - D: lifecycle (install/uninstall, adapter eval, world change)
  - E: anti-corruption (renderChatLog→renderChatInput,
    combatInactive synthesis, combatRound arg normalization)
  - F: semver matcher
  - G: adapter loading (validation, dedup, factory failure)
- tests/perf.mjs — 6 assertions. Median 0.0003ms/fire
  (333x under the 0.1ms budget). Heap delta 2.8MB across 10k fires.
- tests/test-helpers.mjs — Foundry stub (Hooks, game, ui).

## Archive

scripts/_archive/v0.1.0/ — v0.1.0 catalog moved here for git
history. The 18 handlers, system adapters, and encounter.js stub
all live there but are not part of the v0.2.0 module.

tests/_archive_v0.1.0_*.mjs — v0.1.0 test files renamed with
prefix to avoid colliding with v0.2.0 files.

## Manifest

- module.json: bumped to 0.2.0; download URL points at the new zip.
- package.json: bumped to 0.2.0; added test:perf script.
- README.md: rewritten for v0.2.0.

Push: Gitea only.

# Hax's Tools — Hooks Lib
# Hax's Tools — Hooks Lib (`hax-hooks-lib`)
Foundry VTT module (id: `hax-hooks-lib`) that turns Foundry's hook soup
(dnd5e, combat, token updates) into a clean, normalized event stream.
**Library-only** — no UI, no settings, no chat output. Designed to be
consumed by any module that wants Foundry events in a stable shape.

stream. **Library-only** — no UI, no settings, no chat output. Designed to

Part of the **Hax's Tools** umbrella. Consumers today: `battle-focus`
(encounter + journal + summary) and `its-achievable` (achievements,
rewards, wall, HUD). System-specific knowledge (dnd5e rolls, PF2e, etc.)
lives in separate adapter repos that declare Foundry + system version
ranges they support.
## v0.2.0 — generic Foundry hook facade
v0.2.0 is a complete rewrite. v0.1.0 shipped as a curated-event catalog
(a list of hand-written handlers for 18 specific Foundry events). v0.2.0
replaces that with a **generic facade**:
- Subscribes to every relevant Foundry hook (combat lifecycle, all
document CRUD, canvas/UI, dnd5e v2 roll hooks, etc.).
- Emits a uniform envelope — `{ts, hook, args}` — with no domain
interpretation.
- Consumers write queries against the envelope. "When bob takes damage"
is a consumer-side query, not a hook name the library knows about.
- System-specific derived events (e.g. "dnd5e attack roll") live in
separate adapter repos. Adapters register a manifest with Foundry +
system version ranges; the library evaluates at ready and loads
matching adapters.
**Why this shape:** Foundry's hook names and arities change between
versions. The library absorbs that churn (§9 + §10 of the contract) so
consumers don't have to rewrite every Foundry upgrade.
## Status
v0.1.0 — initial extraction from `battle-focus` v0.5.0-alpha.12. The
`scripts/events/` and `scripts/systems/` content is a verbatim copy
of the battle-focus versions, with module-id log strings retagged
from `battle-focus` to `hax-hooks-lib`.
v0.2.0 — generic facade per `docs/HOOK_CONTRACT.md`. Smoke test: 554/554
assertions. Perf test: median 0.0003ms/fire (333× under the 0.1ms budget).
Stage 1 of the split plan: ship this repo without changing
battle-focus's behavior. Stage 2 will flip battle-focus to import
from here and delete the local copy.
## Envelope shape
## Event Shape
Every event is a plain object with at minimum:
Every fire produces exactly one envelope:
```js
{
kind: "combat-start", // stable string id
ts: 1719000000000, // epoch ms when handler fired
// ... kind-specific fields
ts: 1719000000000, // epoch ms when Foundry fired
hook: "updateActor", // the Foundry hook name (normalized; see §9)
args: [doc, change, options, userId] // positional args, verbatim
}
```
Handler functions in `scripts/events/core/` and `scripts/events/dnd5e/`
return the event object (or `null` to drop it). The registry calls the
consumer's `onEvent(event)` callback for any non-null return.
## Event catalog
Core (system-agnostic, always loaded):
- `combat-start`, `combat-end`, `combat-inactive`, `combat-turn`, `combat-round`
- `combatant-add`, `combatant-remove`
- `pre-update-actor`, `update-actor`, `pre-update-token`, `update-token`, `pre-update-item`, `update-item`
- `create-active-effect`, `delete-active-effect`
- `token-avatar-change`
D&D 5e (loaded when `game.system.id === "dnd5e"`):
- `attack-roll`, `damage-roll`
That's it. No `kind`, no normalized fields, no consumer metadata.
Consumers that want `{kind, actorId, delta}` build that themselves from
`args`. This is intentional: the library is the boundary that absorbs
Foundry version churn.
## Public API (on `game.modules.get("hax-hooks-lib").api`)
- `loadSystems({ currentSystemId, systemVersion })` → array of active
system adapters (`[{ id, label, match, events }]`). The `core`
adapter is always present; other adapters are filtered by `match()`.
- `registerAllEvents(systems, onEvent)` → registers every event from
every active system via `Hooks.on(...)`. The `onEvent` callback is
invoked once per non-null handler return, awaited. Returns the array
of registered event defs (for introspection).
```js
import { subscribe, subscribeMany, subscribeAll } from
game.modules.get("hax-hooks-lib").api;
Consumers should call `registerAllEvents` from their `ready` hook and
provide their own `onEvent(event)` to drive their downstream pipeline.
// Single hook:
const unsub = subscribe("updateActor", (envelope) => {
const [actor, change] = envelope.args;
// ...
});
## Dependencies
// Batch subscribe (atomic):
subscribeMany({
updateActor: handleActorUpdate,
createToken: handleTokenCreate,
});
None. This is a leaf library.
// Every hook (for audit logs):
subscribeAll((envelope) => log(envelope));
## Architecture notes
// One-shot cleanup:
unsub(); // or unsubscribeAll() to purge everything
```
- **Single chokepoint:** `registerEvent()` is the only place that
wraps a Foundry hook into the normalized shape. Adding a new event
type = add one file + one line in the relevant system adapter.
- **System loader:** `scripts/systems/loader.js` filters system
adapters by `game.system.id`. Adding a new system = add one file
in `scripts/systems/` + one import line.
- **Context helper:** `$ctx()` returns the active event's metadata
for the duration of the handler call. Use it inside a handler to
log with the event id, or to read which system emitted it.
### System adapters
A system adapter is a separate Foundry module. At its `init`, it calls:
```js
hooksLib.api.registerSystemAdapter({
id: "hax-hooks-dnd5e",
moduleId: "hax-hooks-dnd5e",
system: { id: "dnd5e", versions: ">=5.2.0 <5.3.0" },
foundryVersions: ">=13 <15",
factory: () => [ /* derived-event registrations */ ],
});
```
The library evaluates the manifest against `game.system.id` + version
and `game.version` at `ready`. Matching adapter factories are called
once. Non-matching adapters log a warning naming the version mismatch
(or silently skip for non-matching system).
## Subscribed hook set (v0.2.0)
Lifecycle, document CRUD (Actor/Token/Item/Scene/JournalEntry/
ActiveEffect/Combat/Combatant), combat lifecycle, chat & rolls (incl.
dnd5e v2 roll hooks), canvas/scene/UI (canvasInit/Ready/Pan, controlToken,
hoverToken, targetToken, lighting/sightRefresh, collapseSidebar,
changeSidebarTab, getSceneControlButtons, renderChatMessage,
renderChatInput, renderJournalPageSheet, rtcSettingsChanged), and more.
Full list: `scripts/internal/registered-hooks.js`.
## Error containment
If a consumer callback throws, the library catches it, logs via
`console.error` with the `[hax-hooks-lib]` prefix and the hook name,
and continues dispatching to subsequent callbacks. Errors never
propagate to Foundry's hook chain.
## Tests
`tests/verify-hooks-lib.mjs` is a minimal smoke test that exercises
the registry + a single event without booting Foundry. Foundry-load
verification happens in battle-focus's E2E suite (the test driver
registers hooks-lib's events through battle-focus's consumer path
and confirms the event stream flows end-to-end).
```bash
npm test
npm test # 554 assertions in ~0.4s, no Foundry needed
npm run test:perf # median 0.0003ms/fire, heap delta check
```
See `tests/PLAN.md` for what we test and what we don't. The Foundry-load
test (Playwright against a live Foundry) is deferred to when a real
consumer (battle-focus) migrates and exercises it.
## Architecture notes
- **One envelope shape, one dispatcher.** Adding a new Foundry hook is
one entry in `scripts/internal/registered-hooks.js`. No new file.
- **System adapters are repos, not files.** Each system's derived
knowledge is its own module with its own version cadence.
- **Anti-corruption (§9-§10):** library subscribes to BOTH v13 and v14
hook names where applicable; consumers see stable envelope names.
- **Async dispatch (microtask) by default.** pre-* + combat* +
applyActiveEffect + get*Context dispatch sync because their return
values matter.
## Dependencies
None. Library-only; system adapters depend on this, not the other way
around.

// settings, does not post chat. Consumers (battle-focus, Its-Achievable,
// …) import the public API from this file and call `registerAllEvents`
// from their own `ready` hook with their own onEvent callback.
// Generic Foundry hook facade per HOOK_CONTRACT.md. No domain
// interpretation. Subscribes to every Foundry hook in the registered
// set (§6), emits a uniform {ts, hook, args} envelope, dispatches
// to consumers via the subscribe primitives (§3). System-specific
// knowledge lives in separate adapter repos (§5).

// Lifecycle:
// init: nothing (we have no settings, no patches, no UI to register).
// ready: consumers call loadSystems() then registerAllEvents(systems, onEvent).

// 2. loadSystems({currentSystemId: "dnd5e"}) returns core + dnd5e.
// 3. registerAllEvents wires every event handler into Hooks.on for
// the declared hook name.
// 4. When a Foundry hook fires, the registered handler returns a
// normalized event object, and onEvent is invoked exactly once
// with that object.
// 5. registerEvent rejects event defs missing id/hook/handler.
// 6. Handlers that return null do NOT trigger onEvent.
//
// Full E2E (the real story) is battle-focus's
// tests/verify-battle-focus-v5.mjs, which loads hooks-lib as a
// Foundry module and runs 220+ assertions against the event stream.
