Each callback issues at most a handful of single-shot Tesla + requests bounded by `http_timeout`. No retry, no backoff, no + circuit-breaker — transient failures (5xx, timeout, nxdomain) of + the *primary* request (`packument` for `fetch_adaptor/1` and + `fetch_icon/2`, `search` for `list_adaptors/0`) surface as + `{:error, term()}` unchanged. Schema and tarball fetches inside + `fetch_adaptor/1` are best-effort: a failure degrades the affected + field to `nil` rather than failing the whole record (matches the + `Local` strategy's behaviour for missing files). + + ## Configuration + + Reads `:registry_url` and `:http_timeout` via + `Lightning.Adaptors.Config.strategy_opts(__MODULE__)`, with the + defaults from §5.1 of the design doc baked in here so the module + works even when no Application env block is set. `:max_concurrency` + is reserved by §5.1 for cross-invocation cold-miss capping at the + Store layer; it is intentionally

Supervisor takes an explicit :strategy opt (defaulting to Config.strategy/0) and stashes {strategy, source} in :persistent_term keyed by {Supervisor, name}. Store callers resolve both via the new strategy/1 and source/1 helpers — no Application.put_env, no shared mutable state, async-safe. Pattern follows PR #4562: thread the dependency through the opts, expose it via the supervisor instance, mock the behaviour (not the caller) in tests. test_helper.exs defines StrategyMock against the Strategy behaviour.

Sep 17 00:00:00 2001 From: Stuart Corbishley Date: Fri, 15 May 2026 11:18:20 +0200 Subject: [PATCH 20/39] Decompose Lightning.Adaptors.NPM and migrate tests to Bypass Split the monolithic NPM strategy into three focused sub-modules under Lightning.Adaptors.NPM.{Registry, Schema, Tarball}, each owning its own Tesla client and upstream concern. The NPM module is now a thin orchestrator (~96 lines) implementing the Strategy behaviour by delegating to the sub-modules. Migrate the test suite from Mox-stubbed Tesla envs to Bypass-driven HTTP fixtures. Each sub-module gets its own test file with its own Bypass instance; the orchestrator test exercises real HTTP through the composed pipeline. The Tesla adapter is overridden per-test, so the 21 other test files relying on the global Lightning.Tesla.Mock are unaffected. Add :jsdelivr_url to the NPM strategy_opts block, mirroring the existing :registry_url. This makes both upstreams swappable at runtime (e.g. for pointing dev/CI at a local Verdaccio cache). Apply the @openfn/language-* filter to Registry.list_adaptors/0, matching legacy AdaptorRegistry semantics (excludes @openfn/cli, @openfn/buildtools, and other non-language packages). The icon-strategy reshape (icons live in the OpenFn GitHub monorepo, not in per-package npm tarballs) is deferred to a follow-up plan; see context/lightning/adaptors/02-deferred-icon-strategy-fix.md. --- lib/lightning/adaptors/npm.ex | 316 ++----------- lib/lightning/adaptors/npm/registry.ex | 195 ++++++++ lib/lightning/adaptors/npm/schema.ex | 83 ++++ lib/lightning/adaptors/npm/tarball.ex | 139 ++++++ test/lightning/adaptors/npm/registry_test.exs | 199 +++++++++ test/lightning/adaptors/npm/schema_test.exs | 86 ++++ test/lightning/adaptors/npm/tarball_test.exs | 159 +++++++ test/lightning/adaptors/npm_test.exs | 417 +++++++----------- test/support/npm_test_helpers.ex | 31 ++ 9 files changed, 1098 insertions(+), 527 deletions(-) create mode 100644 lib/lightning/adaptors/npm/registry.ex create mode 100644 lib/lightning/adaptors/npm/schema.ex create mode 100644 lib/lightning/adaptors/npm/tarball.ex create mode 100644 test/lightning/adaptors/npm/registry_test.exs create mode 100644 test/lightning/adaptors/npm/schema_test.exs create mode 100644 test/lightning/adaptors/npm/tarball_test.exs create mode 100644 test/support/npm_test_helpers.ex diff --git a/lib/lightning/adaptors/npm.ex b/lib/lightning/adaptors/npm.ex index c1fbcccc2d..307d7218cb 100644 --- a/lib/lightning/adaptors/npm.ex +++ b/lib/lightning/adaptors/npm.ex @@ -8,7 +8,7 @@ defmodule Lightning.Adaptors.NPM do `Mix.Tasks.Lightning.InstallAdaptorIcons` into one stateless module: * `c:list_adaptors/0` — single search-API call returning - `name + latest_version` for every `@openfn/*` package. + `name + latest_version` for every `@openfn/language-*` package. * `c:fetch_adaptor/1` — packument fetch + per-version decode, latest-version schema retrieval via jsDelivr, and in-memory icon hashing from the tarball. @@ -17,91 +17,69 @@ defmodule Lightning.Adaptors.NPM do ## HTTP - Tesla + Finch on top of the already-supervised `Lightning.Finch` - pool.

Replace the broken per-package tarball walk with NPM.GitHub, which fetches from raw.githubusercontent.com both in bulk (Scheduler refresh tick) and as a lazy-miss fallback (Store). * Add Strategy.fetch_icons/0 bulk callback; remove icon fields from fetch_adaptor/1 records — Scheduler joins icons in a separate pipeline. * Scheduler runs two parallel pipelines per tick: bulk icons via fetch_icons/0, and per-adaptor diff via list_adaptors + fetch_adaptor. Write failures (Repo upsert, IconCache.write!) now degrade with Logger lines instead of crashing the task silently. * Local strategy implements fetch_icons/0 by walking its configured assets directory. * Delete NPM.Tarball — dead code, icons were never there. --- lib/lightning/adaptors/icon_cache.ex | 9 +- lib/lightning/adaptors/local.ex | 46 ++-- lib/lightning/adaptors/npm.ex | 63 +++--- lib/lightning/adaptors/npm/github.ex | 194 +++++++++++++++++ lib/lightning/adaptors/npm/tarball.ex | 139 ------------ lib/lightning/adaptors/scheduler.ex | 171 +++++++++++++-- lib/lightning/adaptors/store.ex | 52 +++-- lib/lightning/adaptors/strategy.ex | 52 ++++- test/lightning/adaptors/local_test.exs | 57 ++++- test/lightning/adaptors/npm/github_test.exs | 209 ++++++++++++++++++ test/lightning/adaptors/npm/tarball_test.exs | 159 -------------- test/lightning/adaptors/npm_test.exs | 213 ++++++++----------- test/lightning/adaptors/scheduler_test.exs | 175 ++++++++++++++- test/lightning/adaptors/store_test.exs | 195 +++++++++++++++++ test/support/npm_test_helpers.ex | 31 --- 15 files changed, 1207 insertions(+), 558 deletions(-) create mode 100644 lib/lightning/adaptors/npm/github.ex delete mode 100644 lib/lightning/adaptors/npm/tarball.ex create mode 100644 test/lightning/adaptors/npm/github_test.exs delete mode 100644 test/lightning/adaptors/npm/tarball_test.exs delete mode 100644 test/support/npm_test_helpers.ex diff --git a/lib/lightning/adaptors/icon_cache.ex b/lib/lightning/adaptors/icon_cache.ex index a843b36470..22147f6813 100644 --- a/lib/lightning/adaptors/icon_cache.ex +++ b/lib/lightning/adaptors/icon_cache.ex @@ -18,9 +18,12 @@ defmodule Lightning.Adaptors.IconCache do don't need to keep old versions on disk.

Each child gets the opts its own start_link/1 declares (not the speculative shape from the plan); names come from the Supervisor's name helpers. Mount Lightning.Adaptors.Supervisor in application.ex alongside the legacy adaptor_registry_childspec and adaptor_service_childspec. Coexistence is deliberate per REWRITE-2026-05 §9 — the cheap rollback path until Phase B migrates callers. In config/test.exs, point the boot-time supervisor at Lightning.Adaptors.StrategyMock with refresh_interval: 0 so the production-name instance is inert in the test suite. Per-test supervisors override as needed. Drop now-redundant start_supervised!({Supervisor, ...}) calls from the four Phase A unit-test files (channel_broadcaster, invalidator, node_monitor, scheduler) and from the adaptors facade test, since application.ex provides the instance. Where a test needed a custom refresh interval, terminate the application-supplied child first then start a replacement under the same supervisor. Add supervisor_integration_test.exs covering the :rest_for_one crash cascade — a load-bearing decision in §6.5a (Invalidator subscribes at init; a Cachex restart without a downstream cascade would leave it bound to a stale cache). --- config/test.exs | 14 ++ lib/lightning/adaptors/supervisor.ex | 22 ++- lib/lightning/application.ex | 1 + .../adaptors/channel_broadcaster_test.exs | 19 +- test/lightning/adaptors/invalidator_test.exs | 8 +- test/lightning/adaptors/node_monitor_test.exs | 12 +- test/lightning/adaptors/scheduler_test.exs | 19 +- .../adaptors/supervisor_integration_test.exs | 163 ++++++++++++++++++ test/lightning/adaptors_test.exs | 28 +-- 9 files changed, 240 insertions(+), 46 deletions(-) create mode 100644 test/lightning/adaptors/supervisor_integration_test.exs diff --git a/config/test.exs b/config/test.exs index 9641f9e9a6..8ce0f8d6b5 100644 --- a/config/test.exs +++ b/config/test.exs @@ -96,6 +96,20 @@ config :lightning, Lightning.Mailer, adapter: Swoosh.Adapters.Test config :lightning, Lightning.AdaptorRegistry, use_cache: "test/fixtures/adaptor_registry_cache.json" +# Phase A Adaptors.Supervisor config for test boot. +# +# - `:strategy` — the production `Lightning.Adaptors.Supervisor` mounted in +# `application.ex` would default to `Lightning.Adaptors.NPM` and try to +# hit the network on the first Scheduler tick.

Icons are content-addressed (sha8 in the URL) and must be cacheable across users, so authentication is intentionally skipped. The route uses a single :filename path segment rather than the plan's literal :shape-:sha8.:ext — Phoenix's router rejects multiple dynamic entries in one path component. The controller's new 2-arg show/2 head parses shape-sha8.ext via Regex.named_captures and delegates to the existing 4-key clause that the 22 direct-call tests still exercise. AdaptorIconURL.build/3 already emits this shape, so the public URL is unchanged.

The inner Scheduler registers via {:global, …} so callers on any node reach the leader transparently via Erlang distribution; the fictional {:error, :not_leader} surface is removed everywhere (Adaptors facade, MaintenanceLive, refresh_adaptors task). Test isolation fixes uncovered while verifying: * Drop the boot Cachex.clear/1 Task — redundant (Cachex is ETS-backed, empty at every (re)start under :rest_for_one) and a real race against test setups that put! into the cache immediately after start_supervised!. * Pin Lightning.Adaptors.IconCache to a per-OS-PID directory at test_helper boot and wipe on entry. The default path under System.tmp_dir!/lightning/adaptor_icons is shared across mix test invocations, and System.unique_integer/1 recycles per VM — stale files from a prior run masked Mox expectations by short-circuiting IconCache.cached?/4. * Replace two FIFO-dispatched expect/4 calls in store_test and scheduler_test with single multi-clause expect/4 calls so Mox routes by pattern when parallel tasks fan out in arbitrary order. --- lib/lightning/adaptors.ex | 16 ++- lib/lightning/adaptors/scheduler.ex | 25 ++-- lib/lightning/adaptors/supervisor.ex | 82 +++++++++++--- .../live/maintenance_live/index.ex | 4 +- lib/mix/tasks/lightning.refresh_adaptors.ex | 23 ++-- mix.exs | 1 + mix.lock | 1 + .../adaptors/highlander_integration_test.exs | 107 ++++++++++++++++++ test/lightning/adaptors/node_monitor_test.exs | 8 +- test/lightning/adaptors/scheduler_test.exs | 71 ++++++------ test/lightning/adaptors/store_test.exs | 20 ++-- .../adaptors/supervisor_integration_test.exs | 84 +++++++++----- test/lightning/adaptors/supervisor_test.exs | 42 +++++-- test/lightning/adaptors_test.exs | 17 ++- .../tasks/lightning.refresh_adaptors_test.exs | 34 +----- test/test_helper.exs | 26 +++++ 16 files changed, 392 insertions(+), 169 deletions(-) create mode 100644 test/lightning/adaptors/highlander_integration_test.exs diff --git a/lib/lightning/adaptors.ex b/lib/lightning/adaptors.ex index 6a7bbd6e27..27a2a3e20c 100644 --- a/lib/lightning/adaptors.ex +++ b/lib/lightning/adaptors.ex @@ -62,20 +62,24 @@ defmodule Lightning.Adaptors do def resolve_version(_name, version), do: {:ok, version} - @spec refresh_now() :: :ok | {:error, :not_leader} + @spec refresh_now() :: :ok | {:error, term()} def refresh_now, do: refresh_now(@sup) - @spec refresh_now(atom()) :: :ok | {:error, :not_leader} + @spec refresh_now(atom()) :: :ok | {:error, term()} def refresh_now(sup), - do: Scheduler.refresh_now(AdaptorsSupervisor.scheduler_name(sup)) + do: Scheduler.refresh_now(AdaptorsSupervisor.global_scheduler_name(sup)) - @spec refresh_package(String.t()) :: :ok | {:error, :not_leader | term()} + @spec refresh_package(String.t()) :: :ok | {:error, :not_found | term()} def refresh_package(name) when is_binary(name), do: refresh_package(@sup, name) @spec refresh_package(atom(), String.t()) :: - :ok | {:error, :not_leader | term()} + :ok | {:error, :not_found | term()} def refresh_package(sup, name) when is_binary(name), - do: Scheduler.refresh_package(AdaptorsSupervisor.scheduler_name(sup), name) + do: + Scheduler.refresh_package( + AdaptorsSupervisor.global_scheduler_name(sup), + name + ) @doc false def icon_meta(name), do: icon_meta(@sup, name) diff --git a/lib/lightning/adaptors/scheduler.ex b/lib/lightning/adaptors/scheduler.ex index 34e7ccb5d8..654be8eb82 100644 --- a/lib/lightning/adaptors/scheduler.ex +++ b/lib/lightning/adaptors/scheduler.ex @@ -4,9 +4,13 @@ defmodule Lightning.Adaptors.Scheduler do source's ledger via the configured strategy, persists through `Lightning.Adaptors.Repo`, and broadcasts `{:changed, name, source}`. - Wrapped by `HighlanderPG` in production so only one node in the cluster - runs the scheduler at a time.

Then close the gap for already-broken rows: * Repo.list_missing_icons/1 + update_icons/3 — icon-only writer that bypasses upsert_adaptor/1 (which would rewrite adaptor_versions). * Scheduler self-heal: every tick tops up rows with NULL icon shas using the icons map we already fetched.

Add Lightning.Adaptors.PackageName helper for adaptor-name parsing. Add test/support/adaptor_test_helpers.ex with seed_adaptor / seed_credential_schema / seed_common_packages and Cachex warming. Wire it into the test files that previously relied on the implicit AdaptorRegistry seed. Known follow-up: credential-form field order regressed because the new Lightning.Adaptors.Repo stores schema_data as jsonb (:map), which flattens JSON property order. Two affected tests (@tag :skip with TODO) covering postgresql and dhis2 credential creation will be re-enabled when the storage shape is fixed in a follow-up PRD. --- lib/lightning/adaptors/package_name.ex | 64 +++++ lib/lightning/ai_assistant/ai_assistant.ex | 2 +- lib/lightning/credentials.ex | 11 +- .../channels/run_with_options.ex | 4 +- .../channels/workflow_channel.ex | 11 +- .../live/job_live/adaptor_picker.ex | 37 ++- lib/lightning_web/live/workflow_live/edit.ex | 6 +- .../live/workflow_live/editor_pane.ex | 2 +- .../live/workflow_live/job_view.ex | 2 +- test/integration/web_and_worker_test.exs | 11 + test/lightning/adaptors/package_name_test.exs | 73 +++++ .../ai_assistant/ai_assistant_test.exs | 8 +- test/lightning/credentials/schema_test.exs | 15 + test/lightning/credentials_test.exs | 13 + .../channels/run_channel_test.exs | 16 ++ .../channels/run_with_options_test.exs | 42 ++- .../channels/workflow_channel_test.exs | 26 +- .../live/credential_live_test.exs | 17 ++ .../live/job_live/adaptor_picker_test.exs | 39 ++- test/lightning_web/live/project_live_test.exs | 8 + .../live/workflow_live/collaborate_test.exs | 8 + .../live/workflow_live/edit_test.exs | 39 ++- .../live/workflow_live/editor_test.exs | 13 + test/support/adaptor_test_helpers.ex | 260 ++++++++++++++++++ 24 files changed, 686 insertions(+), 41 deletions(-) create mode 100644 lib/lightning/adaptors/package_name.ex create mode 100644 test/lightning/adaptors/package_name_test.exs create mode 100644 test/support/adaptor_test_helpers.ex diff --git a/lib/lightning/adaptors/package_name.ex b/lib/lightning/adaptors/package_name.ex new file mode 100644 index 0000000000..a629fa74c9 --- /dev/null +++ b/lib/lightning/adaptors/package_name.ex @@ -0,0 +1,64 @@ +defmodule Lightning.Adaptors.PackageName do + @moduledoc """ + NPM-style package-name parsing and worker wire-shape recomposition for + the `Lightning.Adaptors.*` subsystem. + + This module is the single source of truth for the legacy + `AdaptorRegistry.resolve_adaptor/1` and `resolve_package_name/1` + contracts, ported to read through the `Lightning.Adaptors` facade. + + `parse/1` splits `"name@version"` strings; `to_wire/1` resolves the + `latest` literal through `Lightning.Adaptors.resolve_version/2`, + preserves `"name@local"` as a literal regardless of source, and emits + `"name@local"` under a `:local` strategy source. + """ + + alias Lightning.Adaptors + alias Lightning.Adaptors.Config + + @package_name_regex ~r/(@?[\/\d\n\w-]+)(?:@([\d\.\w-]+))?$/ + + @spec parse(nil) :: {nil, nil} + def parse(nil), do: {nil, nil} + + @spec parse(String.t()) :: {String.t() | nil, String.t() | nil} + def parse(package_name) when is_binary(package_name) do + case Regex.run(@package_name_regex, package_name) do + [_, name, version] -> {name, version} + [_, _name] -> {package_name, nil} + _ -> {nil, nil} + end + end + + @spec to_wire(String.t() | nil) :: String.t() + def to_wire(adaptor) do + case parse(adaptor) do + {nil, nil} -> "" + {name, version} -> recompose(name, version, adaptor) + end + end + + defp recompose(name, "local", _original), do: "#{name}@local" + + defp recompose(name, version, original) do + case Config.current_source() do + :local -> + "#{name}@local" + + _ -> + case version do + "latest" -> + case Adaptors.resolve_version(name, "latest") do + {:ok, resolved} -> "#{name}@#{resolved}" + {:error, _} -> "#{name}@latest" + end + + nil -> + original + + _concrete -> + original + end + end + end +end diff --git a/lib/lightning/ai_assistant/ai_assistant.ex b/lib/lightning/ai_assistant/ai_assistant.ex index b95886e1a4..b6ad226fee 100644 --- a/lib/lightning/ai_assistant/ai_assistant.ex +++ b/lib/lightning/ai_assistant/ai_assistant.ex @@ -614,7 +614,7 @@ defmodule Lightning.AiAssistant do %{ session | expression: expression, - adaptor: Lightning.AdaptorRegistry.resolve_adaptor(adaptor) + adaptor: Lightning.Adaptors.PackageName.to_wire(adaptor) } end diff --git a/lib/lightning/credentials.ex b/lib/lightning/credentials.ex index ed237b5d75..3795685f58 100644 --- a/lib/lightning/credentials.ex +++ b/lib/lightning/credentials.ex @@ -575,15 +575,12 @@ defmodule Lightning.Credentials do """ @spec get_schema(String.t()) :: Credentials.Schema.t() def get_schema(schema_name) do - {:ok, schemas_path} = Application.fetch_env(:lightning, :schemas_path) - - File.read("#{schemas_path}/#{schema_name}.json") - |> case do - {:ok, raw_json} -> - Credentials.Schema.new(raw_json, schema_name) + case Lightning.Adaptors.schema(schema_name) do + {:ok, schema_map} -> + Credentials.Schema.new(schema_map, schema_name) {:error, reason} -> - raise "Error reading credential schema.

Adds a custom Ecto type that accepts both maps (legacy rows) and binaries at the schema layer. Removes the two @tag :skip markers introduced by PRD #5 for the postgresql/dhis2 credential tests.

(Only reach for config-driven "don't boot it +in `:test`" when something you *cannot* hand a pid — a Plug, a distant caller — +calls the API with the default name. That is the exception, not the default.) + +### Argument order convention: server ref first, with a default + +This is the OTP-wide convention and it is near-universal: +`GenServer.call(server, …)`, `Agent.get(agent, …)`, +`Registry.lookup(registry, …)`, `Phoenix.PubSub.broadcast(pubsub, …)`, +`Oban.insert(name \\ Oban, changeset)`, `Mox.allow(mock, …)`, +`Ecto.Adapters.SQL.Sandbox.allow(repo, …)` — the addressed thing is the +**subject**, so it leads. + +Critically, **first-with-default is the idiom that produces the `/1` + `/2` +pair cleanly**: + +```elixir +def fetch(server \\ __MODULE__, key) +# fetch(key) -> arity 1, server defaults to __MODULE__ (production) +# fetch(pid, key) -> arity 2, explicit instance (test) +``` + +Production never names anything; the test injects a pid through the *same* +function. **The signature is the injection seam.** That is why this convention +is load-bearing, not stylistic. + +The one principled exception: **pipeline-first APIs put the instance last** — +`Finch.build(:get, url) |> Finch.request(MyFinch)` — because the data being +transformed is the subject and the instance is configuration, so it reads in a +pipe.

The two axes (the centrepiece) + +People — and AI harnesses — reliably weld together two **independent** problems. +Welding them is what makes refactors thrash. Keep them apart: + +1. **Axis 1 — where does per-instance config / identity live?** +2. **Axis 2 — which process actually invokes the injected dependency?** + +`:persistent_term` (and runtime `Application.put_env`, and naked global ETS) is +the wrong answer to **Axis 1**. The `set_mox_global` / `async: false` / +`Sandbox.allow` pain is entirely **Axis 2**. Fixing Axis 1 does not fix Axis 2 +— but it makes Axis 2 *legible*, which is the precondition for fixing it. + +### `:persistent_term` is a smell + +Treat `:persistent_term`, runtime `Application.put_env`, and naked global ETS +for per-instance config as a **smell requiring explicit justification**. Its +presence means someone reached for *stored state* when *structure* is the +functional answer. The legitimacy litmus: + +> **Does this value ever need to differ between two tests running at the same +> time?** If yes, it cannot live in any global store — inject it. If no, and +> it is genuinely hot-read and fixed at boot, `:persistent_term` is fine +> (Phoenix/Ecto use it internally for exactly that). + +### Worked example: `Lightning.Adaptors.Supervisor` + +The adaptors supervisor is otherwise *exemplary* — its moduledoc states the +principle verbatim, it derives every child name via `Module.concat(name, …)` +(a fixed child set with full multi-instance async isolation and **zero +Registry**), and it injects the `:strategy` as an explicit opt with a +production default. One wart: + +```elixir +# supervisor.ex init/1 — strategy & source are LOCALS here… +strategy = Keyword.get(opts, :strategy, Config.strategy()) +:persistent_term.put(meta_key(name), %{strategy: strategy, source: source_for(strategy)}) +# …then the same init/1 injects cache/tasks/source_topic into child specs +# explicitly, two lines down — but routes strategy/source through a global. +``` + +`Scheduler` then re-fetches it from that global *at call time*: + +```elixir +# scheduler.ex — strategy materialises from nowhere, with no traceable owner +strategy = AdaptorsSupervisor.strategy(state.sup) # :persistent_term.get/1 +strategy.fetch_adaptor(name) +``` + +An investigation of every call site classified this **case (b): avoidable**. +Nothing reaching `Store` lacks the strategy/source at a point where it is +knowable; there is exactly one hardcoded production instance, so even the +stateless facade-from-web path collapses to "boot config for the one instance," +not a dynamic lookup. The generalisable tell: + +> **Global storage smuggling a value past a structural boundary that was +> already open two lines away and already carrying its siblings across.** + +The fix is Axis 1: inject `strategy`/`source` into the child specs the +supervisor is *already building* (it has them in scope), and let `Scheduler` +hold them in its state — exactly as it already does for `source` at `init/1`. + +### Why that makes Axis 2 legible + +Before: you cannot tell *which process* will call `StrategyMock`, because the +value appears from a global with no owner — so you reach for `set_mox_global` +and the suite goes serial. + +After injection: `Scheduler` visibly owns the strategy in its state, so the +mock's caller is obvious and you can scope the allowance: + +```elixir +# Axis 2 recipe — explicit allowance, async-safe +pid = start_supervised!({Lightning.Adaptors.Supervisor, + name: name, strategy: StrategyMock}) +Mox.allow(StrategyMock, self(), Process.whereis(scheduler_name(name))) +``` + +When the pid does not exist yet at setup time (leader election, lazy start), +use the **deferred-resolver form** of `Mox.allow/3` — the trick people forget: + +```elixir +Mox.allow(StrategyMock, self(), fn -> + :global.whereis_name(scheduler_name(name)) +end) +``` + +Mox resolves the pid lazily on first mock invocation, sidestepping the race. +Tasks started via `Task.Supervisor.async/async_nolink` carry `$callers`, so +Mox walks back to the allowed parent automatically; `start_child` +(fire-and-forget) does not propagate and needs its own allowance. + +`Mox.allow/3` and `Ecto.Adapters.SQL.Sandbox.allow/3` are **one concept** — +same signature, same ownership model (a test owns a resource and explicitly +lends it to processes it spawns). Mox's was modelled on Ecto's. + +> **When `set_mox_global` is legitimate, not a cop-out:** explicit allow is the +> default; its cost scales with how many *process hops* the mocked call +> traverses and how *dynamic* those pids are. `set_mox_global` (forcing +> `async: false` for that case) is the correct escape hatch when the hop graph +> is dynamic and deep — `HighlanderPG`-wrapped leader election is the textbook +> case. Try the deferred-resolver form *first*; most cases are not Highlander. + +--- + +## 3. Dynamic populations: when a Registry *is* earned + +When the population is genuinely open-ended and keyed by runtime data, and the +caller does not hold the pid — `DynamicSupervisor` + `Registry` + `:via`. +`Lightning.Collaborate` is the worked example: N sessions/documents keyed by +`document_name`, looked up by a LiveView that did not start them. + +```elixir +SessionSupervisor.start_child( + {Session, workflow: workflow, user: user, + name: Registry.via({:session, "#{document_name}:#{session_id}", user.id})} +) +``` + +Two valid shapes, document the trade-off: + +- **One Registry per top-level instance** (Oban): perfect isolation, but the + instance name threads through every public function + (`Oban.insert(MyApp.Oban, …)`). +- **One global Registry, key-namespaced** (Lightning collaboration): the public + API stays clean (`Collaborate.start/1` takes no name); isolation depends on + keys being genuinely unique. Correct when identity is naturally unique + (workflow + session); risky if a test can reuse a key. + +### The "earned name → config lookup" reference + +If a **stateless synchronous** caller genuinely holds only a name *and* the +population is dynamic, a name → config lookup is justified — and even then it +is **ETS-per-instance, never `:persistent_term`**. `commanded/eventstore` hit +this exact requirement and chose: one named ETS table (`read_concurrency: +true`) owned by a GenServer, holding `{name, pid, ref, store, config}`, the +owner pid monitored so the row **self-deletes on shutdown**. It explicitly +rejected `:persistent_term` because instances churn under async tests and +`:persistent_term` writes/erases trigger a global GC scan. The bonus: an +owner-monitored ETS table needs no manual cleanup function (cf. the adaptors +`forget/1` wart and its "we don't call this automatically because GC is +expensive" comment). + +--- + +## 4.
