-fremtidig vision. De er ikke implementeret af Journal-modellen, servicen eller service-manageren.
+## 8. Componenter og det centrale Registry
+
+En Nenjim component er en færdigkonstrueret byggeklods, som er klar til brug. Rollen som service, applikation,
+algoritme eller adapter bestemmes af den applikation, som bruger componenten; Registry-API'et bruger derfor det
+fælles ord `component` og ikke `plugin`. `NenjimComponent` er en ren marker interface. En startbar component kan
+desuden implementere `NenjimApplication`, som kun lover `start()` og ikke en fælles stop-operation.
+
+En `NenjimComponentId` er registration metadata i ét Registry og er ikke en egenskab ved objektet. ID-formatet er
+lower-case ASCII med dot-separated segments og valgfrie interne bindestreger, f.eks. `nenjim.registry.service` og
+`assetaz.price-source.raydium-pool.eve-usdt`. Det samme objekt må registreres under flere forskellige ID'er, og én
+registration bliver automatisk synlig gennem alle component interfaces, som objektet implementerer. Registry- og
+application-view af Registry-objektet har derfor samme ID og samme object identity.
+
+`NenjimRegistryService` er det read-only katalog, som almindelige consumers modtager gennem constructor injection.
+Det kan returnere et immutable registration-order snapshot af ID'er for et component interface eller slå ét ID op
+gennem et forventet interface. Et manglende ID giver `null`; et eksisterende ID med forkert interface er en caller
+programming error. Public API'et kan ikke registrere eller fjerne componenter.
+
+`NenjimRegistryServiceManagerImpl` konstruerer og starter Registry'et, registrerer Registry og manager først og
+konstruerer derefter den nuværende hardcodede component graph i dependency order. Den package-private admin-view er
+kun managerens registrationshandle og er hverken en component eller public API. Registration starter ikke et
+objekt, og Registry'et forbliver internt åbent for senere registration efter startup.
+
+Applikationen ejer sine konkrete valg og sin activation. Tickerens initiale configuration vælger eksplicit
+`assetaz.price-source.raydium-pool.eve-usdt` gennem Registry'et; den hardcodede price source er registreret, men
+inaktiv. Manageren starter kun den nuværende eksplicitte, dependency-safe liste: Ticker, Production Evelyn, Test
+Evelyn, Production IOU Burner og Mission Control. Alarmen og øvrige tidligere udkommenterede applikationer bliver
+ikke automatisk aktiveret. `com.r35157.nenjim.hubd.Main` er kun det yderste Java-bootstrap; `Main.main(...)` starter
+manageren gennem `NenjimApplication` og er ikke selv en component eller applikation.
+
+Det implementerede Registry er ét katalog og er ikke et authorization-system. Contexts, artifact-version semantics,
+resolution, classloading, automatic discovery, public runtime loading/registration, removal, persistence, events,
+automatic selection/start-all, usage tracking og permissions er fremtidigt arbejde. Journal publishing, remote
+synchronization og signature validation er ligeledes ikke implementeret.

+## Context
+
+See `proposal.md` for motivation and the three delta specs for observable behavior. The current `NenjimHubImpl` constructor eagerly creates one hardcoded object graph, while `start()` activates five objects in a specific dependency-safe order and then waits forever on a latch. Component interfaces are unrelated Java interfaces, startable implementations do not share a lifecycle marker, and the Ticker still receives source instances through a temporary varargs constructor. Human-written Java remains in `.tjava`; Detag runs through the normal Gradle build.
+
+The implementation must retain the current concrete production/test bindings and active subset, including financially relevant wallet/service choices and the deliberately inactive alarm. The Registry is only a catalogue of constructed objects. It must remain injectable and mutable after startup, but it must not grow into an authorization, Context, discovery, resolution, persistence, loading, removal, or lifecycle-ownership system.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- Establish small extractable public component and Registry API packages with reference-only administration and storage.
+- Guarantee deterministic typed lookup, immutable snapshots, alias registrations, recursive interface indexing, and internally consistent concurrent registration/read behavior.
+- Make the Registry manager the only current composition root while preserving hardcoded choices, activation order, and blocking behavior.
+- Make component selection explicit where it belongs to an application/service, beginning with the Ticker's configured Raydium source ID.
+- Remove the duplicate Hub composition surface and directly affected plugin terminology without migrating unrelated prototypes.
+
+**Non-Goals:**
+
+- No general dependency-injection framework, reflection-based construction, start-all loop, lifecycle graph, rollback/stop orchestration, or manager getter for the Registry.
+- No redesign of existing domain lifecycle APIs or constructor wiring where the application does not own a selectable component choice.
+- No migration of legacy `crypto.r35157` prototypes, Context/runtime roadmap contracts, or Journal service startup.
+- No permanent automated tests or production-main validation.
+
+## Decisions
+
+### Synchronized ordered storage provides the first Registry's consistency model
+
+`NenjimRegistryServiceImpl` uses a `LinkedHashMap<NenjimComponentId, NenjimComponent>` as the primary catalogue and a map from component-interface token to ordered mutable ID lists as the secondary index. Registration and both queries synchronize on the Registry object. `getComponentIds(...)` returns `List.copyOf(...)`, so callers receive immutable point-in-time snapshots and later registration cannot mutate an earlier result.
+
+This coarse lock is preferred to concurrent maps plus independently updated lists because registration must update both logical structures atomically and the hardcoded catalogue is small. Copy-on-write structures were considered, but would add more coordination without improving this startup-heavy workload.
+
+### Interface discovery walks class and interface inheritance
+
+Before mutating storage, registration walks the implementation class and its superclasses. For every declared interface, it recursively walks parent interfaces and collects each interface assignable to `NenjimComponent` in insertion-preserving set order. The marker itself is therefore indexed, inherited component interfaces are included, and duplicate inheritance paths add an ID only once. Concrete classes never become keys. `NenjimRegistryServiceAdmin` is naturally excluded because it intentionally does not extend the marker.
+
+Reflection-time discovery is performed once per registration, not during each query. Scanning the primary map on lookup was rejected because issue #76 explicitly requires a secondary type index.
+
+### Validation precedes lifecycle gating and mutation
+
+Lookup arguments are null/type validated before checking started state, giving explicit API-contract failures for malformed calls. Valid queries then require successful Registry startup. Registration validates and computes all index keys before adding the primary record or any index entry; duplicate detection therefore leaves both structures unchanged.
+
+The Registry and manager each retain a separate `startAttempted` flag set at the beginning of the synchronized first call. The Registry publishes `started` only after its start body succeeds. The manager has no restart recovery: any construction or activation failure leaves the attempt consumed, as required. This is separate from existing component-specific restart behavior.
+
+### The manager composes through explicit IDs without exposing administration
+
+The manager creates one Registry implementation and retains public service, package-private admin, and application views of that same object. It starts the application view, then registers the Registry once and the manager once before registering the remaining components in the issue's exact dependency order. Explicit `NenjimComponentId` constants name every binding.
+
+Existing constructor dependencies remain ordinary interface-typed wiring owned by the composition root unless an application/service owns a configurable choice. The Ticker is the first such consumer: its public constructor receives only `NenjimRegistryService` plus explicit price-source IDs and resolves each ID as `PriceSource`. This preserves the selected Raydium source while leaving the registered hardcoded source inactive. Passing the admin view, selecting the first interface match, or adding automatic discovery was rejected because each would violate the ownership boundary.
+
+### Application activation is an explicit ordered ID list
+
+After all registrations, the manager resolves exactly the five enabled IDs through `NenjimApplication` and starts them in the existing order. This both exercises multi-interface indexing and prevents accidental activation of the Registry, manager, alarm, or dormant applications. Registration itself performs no lifecycle work. A generic query-and-start-all loop was rejected because not every registered application is enabled.
+
+### The bootstrap is a class, not a service surface
+
+The final `com.r35157.nenjim.hubd.Main` class is only the outer Java entry point. It constructs a public Registry manager through the `NenjimApplication` view and delegates once; it is neither a `NenjimComponent` nor a `NenjimApplication`. The former composition entry point `com.r35157.nenjim.hubd.impl.ref.Main` and its `NenjimHubImpl` composition implementation remain removed, so the new class does not reinstate that architecture or create a second composition path. Gradle points directly to `com.r35157.nenjim.hubd.Main`.
+
+### Package and terminology migration remains narrow
+
+Only `com.r35157.assetaz.services.ticker.plugins.pricesource` and its implementation subpackages move to `.ticker.pricesource`. The public `PriceSource` becomes a component query interface; `PriceSink` remains an incidental callback interface. Other legacy packages or types containing plugin terminology are untouched.
+
+## Risks / Trade-offs
+
+- [The manager still hardcodes operational component choices] → This change deliberately centralizes rather than generalizes composition; configuration, Context, discovery, persistence, and runtime loading remain separate designs.
+- [One Registry lock serializes all reads with rare registrations] → The catalogue is small and read operations are short; the simple lock guarantees consistency and can be revisited only if profiling warrants it.
+- [A manager failure can leave already-started components active] → The required lifecycle has no common stop and explicitly forbids retry; preserve fail-fast behavior and do not invent rollback semantics.
+- [Adding `NenjimComponent` to cross-module interfaces is source-visible] → Limit the marker to the exact registered query interfaces and do not mark records, value objects, callback sinks, or incidental helpers.
+- [Moving composition code could accidentally expose embedded operational values] → Preserve values without including them in Registry diagnostics or documentation, and inspect diff output with sensitive values redacted.
+- [The public Ticker constructor changes incompatibly] → The old constructor was explicitly documented as temporary; replace its one production call and retain the package-private data-root seam used by existing verification.
+
+## Migration Plan
+
+1. Add component/Registry contracts and the synchronized package-private Registry implementation.
+2. Mark the exact registered query interfaces and active implementations, then move Ticker price-source packages and replace Ticker source injection with Registry-plus-ID selection.
+3. Move the hardcoded construction graph into the Registry manager, register every required ID, activate only the explicit subset, and retain the online wait.
+4. Replace the old Hub API/implementation/main with the thin bootstrap and update Gradle and directly affected documentation.
+5. Validate OpenSpec, compile through Detag/Java, run temporary package-scoped Registry probes, inspect package references and the redacted complete diff, and audit every issue criterion.
+
+Rollback before publication is normal source-control reversal of the uncommitted change. The implementation does not migrate persistent state or mutate external Registry state.

+## Why
+
+Nenjim's current bootstrap directly constructs and starts a hardcoded object graph, leaving ordinary applications without a typed catalogue of independently registered components. A small read-only Registry and a dedicated Registry manager establish component identity, lookup, composition, and lifecycle ownership without prematurely introducing Contexts, resolution, discovery, or runtime loading.
+
+## What Changes
+
+- Add `NenjimComponent` and `NenjimApplication` contracts plus a validated `NenjimComponentId` value type.
+- Add a read-only `NenjimRegistryService`, package-private administration view, and thread-safe reference implementation with ordered interface indexing and single-use startup.
+- Add `NenjimRegistryServiceManager` and its public reference implementation as the one composition root for the current hardcoded component set and explicit active application subset.
+- **BREAKING**: Replace the old Hub interface, `com.r35157.nenjim.hubd.impl.ref.NenjimHubImpl` composition implementation, and `com.r35157.nenjim.hubd.impl.ref.Main` entry point with the thin `com.r35157.nenjim.hubd.Main` bootstrap, whose `Main.main(...)` only starts the Registry manager.
+- Make every registered query interface a Nenjim component and make each registered no-argument lifecycle implementation a Nenjim application without adding a common stop contract.
+- Replace the Ticker's temporary directly injected source objects with an injected public Registry view and explicitly configured source component IDs.
+- **BREAKING**: Rename the directly affected Ticker price-source packages from `.plugins.pricesource` to `.pricesource` and update their imports and terminology.
+- Document component identity, Registry views, application-owned selection/activation, manager-owned construction/registration, and the boundary around deferred runtime features.
+- Preserve the current concrete component choices, dependency-safe startup order, deliberately inactive components, and online wait behavior.
+
+## Capabilities
+
+### New Capabilities
+
+- `nenjim-component-registry`: Defines component/application contracts, component IDs, read-only lookup, internal registration, interface indexing, lifecycle, hardcoded composition, and bootstrap behavior.
+
+### Modified Capabilities
+
+- `assetaz-ticker-service`: Replaces temporary Context/plugin discovery language with explicit component-ID selection through the injected read-only Registry while preserving source lifecycle and history behavior.
+- `assetaz-currency-identity-service`: Transfers ownership of the one shared hardcoded catalogue from the removed Hub composition implementation to the Registry service manager.
+
+## Impact
+
+- Adds public component and Registry APIs under `com.r35157.nenjim.component` and `com.r35157.nenjim.service.registry`, with administration and storage confined to `.impl.ref`.
+- Moves current composition into `NenjimRegistryServiceManagerImpl`, changes the application main class, and removes the superseded Hub implementation path.
+- Updates the registered domain interfaces and lifecycle implementation declarations needed for typed Registry discovery.
+- Changes the public `TickerServiceImpl` construction contract and the Ticker price-source package names.
+- Updates Nenjim, terminology, alarm, and OpenSpec documentation; no new dependency, ValueTag, persistent state, runtime discovery, Context, resolution, classloading, permission, event, removal, or common-stop API is introduced.

+## MODIFIED Requirements
+
+### Requirement: Immutable conflict-free hardcoded catalogue
+The hardcoded Currency Identity Service SHALL preserve the existing AssetAZ currency UUIDs, maintain one current currency value for each UUID, support multiple external references per UUID, reject conflicting UUID or external-identity mappings during initialization, expose no public mutation operation, and be safe for concurrent reads after construction. The Nenjim Registry service manager SHALL create exactly one hardcoded service instance for the current hardcoded component graph, register it as `assetaz.currency-identity.hardcoded`, and SHALL pass that same instance to every component in that graph that requires currency identities.
+
+#### Scenario: Conflicting external mapping
+- **WHEN** initialization maps the same namespace and external identifier to two different AssetAZ UUIDs
+- **THEN** initialization fails with a clear conflict exception
+
+#### Scenario: Conflicting currency metadata
+- **WHEN** initialization provides conflicting current values for the same UUID
+- **THEN** initialization fails with a clear conflict exception
+
+#### Scenario: Compose hardcoded components
+- **WHEN** the Registry service manager constructs the current hardcoded component graph
+- **THEN** it creates and registers one hardcoded Currency Identity Service and injects that same instance into every component that requires it

+## MODIFIED Requirements
+
+### Requirement: Price sources are discovered and lifecycle-managed
+Nenjim SHALL be able to construct and register each price source independently in an initialized but unstarted state without supplying a ticker or sink. The ticker SHALL receive the public Nenjim Registry through constructor injection and resolve its explicitly configured `PriceSource` component IDs, while ordinary ticker clients SHALL NOT receive a public operation for adding or managing sources. The ticker SHALL fail clearly when a configured ID is missing or names a component that does not implement `PriceSource`; it SHALL NOT silently select the first source listed for the interface. The ticker SHALL identify each resolved source by its `TradingPair` and stable source name, reject duplicate identities clearly, start each active source by passing itself as `PriceSink`, and stop every source it started. Source names SHALL be non-empty safe directory components and SHALL reject `/`, `\`, `..`, and control characters without rewriting them. A source SHALL announce typed prices and timestamps only through the sink received at start and SHALL remain unaware of its persistence path. A repeated source start SHALL reject the call before replacing its existing sink.
+
+#### Scenario: Sources are constructed independently
+- **WHEN** the Registry manager constructs and registers a price source before constructing or starting the ticker
+- **THEN** source construction requires neither a `PriceSink` nor a ticker reference and leaves the source unstarted
+
+#### Scenario: Ticker resolves configured source components
+- **WHEN** the ticker initializes its source set from explicit component IDs and an injected public Registry
+- **THEN** it resolves each ID as `PriceSource`, not `PriceSink`, and manages only the resolved configured sources internally
+
+#### Scenario: Missing configured source fails clearly
+- **WHEN** the ticker is configured with an absent component ID or an ID whose object is not a `PriceSource`
+- **THEN** construction fails with a diagnostic identifying the ID and required interface
+
+#### Scenario: Ordinary clients cannot manage sources
+- **WHEN** a caller uses the public `TickerService` contract
+- **THEN** the contract exposes ticker lifecycle and latest-price queries but no source-registration operation
+
+#### Scenario: Distinct configured sources are accepted
+- **WHEN** the ticker resolves two configured sources with different source names or trading pairs
+- **THEN** it accepts both and manages each source independently
+
+#### Scenario: Duplicate persistent identity is rejected
+- **WHEN** the ticker resolves sources with the same trading pair and source name
+- **THEN** initialization fails with an error identifying the duplicate source history
+
+#### Scenario: Unsafe source name is rejected
+- **WHEN** a source name is empty or contains a slash, backslash, `..`, or a control character
+- **THEN** ticker initialization or startup fails clearly without rewriting the source name or creating filesystem content
+
+#### Scenario: Active source lifecycle is managed
+- **WHEN** the ticker starts and later stops with an active Registry-resolved source
+- **THEN** it calls `start` with itself as `PriceSink` and subsequently stops the source without leaving source-owned resources running
+
+#### Scenario: Repeated source start preserves existing sink
+- **WHEN** an already-started source receives another start call with a different sink
+- **THEN** it rejects the call before replacing the sink from the successful start
+
+### Requirement: Ticker exposes typed latest prices
+The ticker SHALL expose the latest successfully persisted `PriceObservation` for a requested `TradingPair` across all active Registry-resolved sources for that pair. A `PriceObservation` SHALL contain exactly an `AssetPrice`, its observation `Instant`, and the stable source name; the `AssetPrice` SHALL contain both its `ΩPriceΩ` value and `TradingPair`. If several active sources provide a pair, latest SHALL be the observation with the greatest `observedAt` timestamp, and its source name SHALL identify its source. A request for a pair with no resolved sources, no active sources, or no successfully persisted observation SHALL throw a clear exception rather than return `null`.
+
+#### Scenario: Latest supported price is available
+- **WHEN** a caller requests a trading pair after at least one observation has been loaded or persisted by an active source
+- **THEN** the ticker returns the successfully persisted observation with the greatest timestamp and its source identity
+
+#### Scenario: Newest observation is selected across sources
+- **WHEN** multiple active sources for one trading pair have successfully persisted observations
+- **THEN** the ticker returns the observation with the greatest `observedAt` across those sources
+
+#### Scenario: Pair has no resolved or active source
+- **WHEN** a caller requests a pair with no configured Registry-resolved source or whose resolved sources are all inactive
+- **THEN** the ticker throws an exception that clearly identifies the unavailable trading pair
+
+#### Scenario: Active pair has no persisted observation
+- **WHEN** a caller requests a pair whose active sources have no successfully persisted observation
+- **THEN** the ticker throws an exception that clearly states that no persisted price is available for that trading pair
+
+### Requirement: Price history explicitly activates each source
+For each configured Registry-resolved source, the ticker SHALL derive an independent history path as `data/assetaz/ticker/<base UUID>/<quote UUID>/<source name>/<safe base symbol>_<safe quote symbol>.prices`. UUIDs SHALL use their unchanged canonical representation and SHALL be the technical trading-pair identity; sanitized symbols SHALL be used only for the human-readable filename. Only an existing file at that exact path SHALL activate the source. The ticker SHALL neither scan for arbitrary sources nor create or migrate missing files or directories. It SHALL load every valid observation using the resolved source's trading pair and source name and select the greatest timestamp across all active histories for each pair, regardless of file order. Empty lines, full-line comments, and inline comments SHALL remain supported. An existing history with no data SHALL activate only that source without an initial observation, while a missing history SHALL leave only that source inactive and emit a warning containing the trading pair, source name, and complete expected path.
+
+#### Scenario: Existing source history activates and restores identity
+- **WHEN** a Registry-resolved source has an existing valid history with permitted whitespace or comments
+- **THEN** that source is active and its observations are restored with its captured trading pair and source name
+
+#### Scenario: Empty source history activates without a price
+- **WHEN** a Registry-resolved source has an existing empty or comment-only history file
+- **THEN** that source is active without an initial observation
+
+#### Scenario: Missing source history leaves only that source inactive
+- **WHEN** one resolved source history is missing while another source for the same pair has an existing history
+- **THEN** the missing source is not started, the existing source remains active, and no missing path is created
+
+#### Scenario: Missing history warning identifies the source
+- **WHEN** a Registry-resolved source's expected history file is absent
+- **THEN** the ticker logs a warning containing its trading pair, source name, and complete expected UUID-based path
+
+#### Scenario: Malformed source history is rejected clearly
+- **WHEN** comment text is removed and a non-empty data line in an active source history lacks a valid UTC timestamp and price
+- **THEN** ticker startup fails with an error containing the history filename, one-based physical line number, and identifying invalid content
+
+#### Scenario: Legacy history is not migrated
+- **WHEN** only `data/assetaz/ticker/EVE_USDC.prices` exists
+- **THEN** the ticker does not read, move, copy, or create a replacement for that legacy file
+
+### Requirement: History uses the human-editable observation format
+Each source history data line SHALL retain the form `<UTC timestamp>:<price>`, where the timestamp uses `uuuuMMddHHmmssSSS'Z'` with millisecond precision in UTC. Trading-pair and source identity SHALL come from the Registry-resolved source and its directory context and SHALL NOT be stored in individual data lines. Automatic writes SHALL append plain data lines only and SHALL leave all existing comments and blank lines untouched.
+
+#### Scenario: Observation is written in the required format
+- **WHEN** any source observation at `2026-08-05T13:15:42.783Z` with price `14.85` is persisted
+- **THEN** the appended line is `20260805131542783Z:14.85`
+
+#### Scenario: Identity is not duplicated in data lines
+- **WHEN** an observation is appended to a source history
+- **THEN** its data line contains neither source name nor trading-pair identity
+
+#### Scenario: Existing operator annotations are preserved
+- **WHEN** the ticker appends an observation to a source history containing comments or blank lines
+- **THEN** those existing lines remain unchanged and the appended observation contains neither a comment nor extra annotation
+
+### Requirement: New observations are durable before publication
+Only an active source resolved and started by the ticker SHALL be allowed to announce an observation. For each accepted announcement, the ticker SHALL validate the source, typed price, and timestamp; construct an observation with the source's captured trading pair and source name; serialize writes to that source history; append and force the data to persistent storage; and only after persistence succeeds consider it for the trading pair's in-memory latest value. Concurrent callbacks from different sources SHALL neither corrupt nor interleave writes, and readers SHALL never observe an unpersisted price. Every accepted observation SHALL be persisted even when an existing observation has a later timestamp, and latest SHALL change only when the newly persisted timestamp is later. If persistence fails, the ticker SHALL report the trading pair, source, and path clearly and preserve the prior latest observation.
+
+#### Scenario: Active resolved source observation is persisted
+- **WHEN** an active source started by the ticker announces a valid price and timestamp
+- **THEN** the ticker appends and forces the observation to that source's history before considering it for latest
+
+#### Scenario: Inactive or unknown source callback is rejected
+- **WHEN** an inactive source or a source not resolved by the ticker announces an observation
+- **THEN** the ticker rejects the callback without persisting or publishing it
+
+#### Scenario: Future-dated observation remains latest
+- **WHEN** an accepted observation is persisted with a timestamp earlier than the current latest observation across active sources
+- **THEN** the accepted observation remains in its source history and the current later observation remains latest
+
+#### Scenario: Concurrent source callbacks remain durable
+- **WHEN** active sources announce observations concurrently
+- **THEN** each successful append is a complete non-interleaved history line and latest identifies the greatest successfully persisted timestamp
+
+#### Scenario: Persistence fails
+- **WHEN** appending or forcing an accepted observation fails
+- **THEN** the failure identifies the trading pair, source, and path, the attempted observation is not published, and the previously persisted latest observation remains available

+## Purpose
+
+Provide one typed, read-only catalogue of constructed Nenjim components and a lifecycle manager that owns the current hardcoded composition without introducing Context or dynamic-loading semantics.
+
+## ADDED Requirements
+
+### Requirement: Components and applications have minimal common contracts
+`NenjimComponent` SHALL be a pure marker with no component-ID property. `NenjimApplication` SHALL extend `NenjimComponent` and expose only `start() throws Exception` as its common lifecycle operation. Domain service interfaces SHALL remain focused on their domain APIs, while a concrete service implementation with a no-argument active start lifecycle SHALL additionally implement `NenjimApplication`.
+
+#### Scenario: One object has more than one registration identity
+- **WHEN** the same component object is registered under two different unused component IDs
+- **THEN** both IDs identify the same object because IDs are Registry metadata rather than object properties
+
+#### Scenario: A service implementation is startable
+- **WHEN** a service implementation has a no-argument active start lifecycle
+- **THEN** the implementation is discoverable as `NenjimApplication` without adding lifecycle operations solely to its domain service interface
+
+#### Scenario: Common stop is unavailable
+- **WHEN** a caller uses `NenjimApplication`
+- **THEN** the contract exposes no common stop operation
+
+### Requirement: Component IDs are canonical validated values
+`NenjimComponentId` SHALL reject null, strip surrounding Unicode whitespace before storage and validation, and accept only lower-case ASCII dot-separated segments whose first character is a letter and whose remaining subparts contain lower-case letters or digits separated by single internal hyphens. Standard record value equality and hashing SHALL define ID equality.
+
+#### Scenario: Surrounding whitespace is canonicalized
+- **WHEN** an ID is constructed from `   nenjim.registry.service   `
+- **THEN** its stored value is `nenjim.registry.service`
+
+#### Scenario: Valid component IDs are accepted
+- **WHEN** IDs such as `nenjim.registry.service`, `assetaz.price-source.raydium-pool`, or `evelyn.service.prod` are constructed
+- **THEN** construction succeeds
+
+#### Scenario: Invalid component IDs are rejected
+- **WHEN** an ID is null or contains uppercase letters, underscores, internal whitespace, an empty segment, a leading or trailing dot, or a malformed hyphen
+- **THEN** construction fails with the specified null or argument exception category and identifies the invalid canonicalized value without exposing secrets
+
+### Requirement: Registry consumers receive only typed read-only lookup
+`NenjimRegistryService` SHALL be a Nenjim component and SHALL expose exactly an ordered-ID lookup by component interface and a nullable typed lookup by component ID and expected component interface. Both operations SHALL reject null arguments. A query type SHALL be an interface extending `NenjimComponent`; concrete classes and ordinary interfaces SHALL be rejected.
+
+#### Scenario: List matching component IDs
+- **WHEN** a caller requests the IDs for a valid component interface
+- **THEN** the Registry returns all registrations indexed under that interface in registration order as an immutable snapshot that is not changed by later registrations
+
+#### Scenario: No component implements an interface
+- **WHEN** a valid component interface has no indexed registration
+- **THEN** the Registry returns an empty immutable list rather than null
+
+#### Scenario: Retrieve a matching component
+- **WHEN** an existing component ID is requested through an interface implemented by its object
+- **THEN** the Registry returns that object cast to the requested interface
+
+#### Scenario: Component ID is missing
+- **WHEN** an unused component ID is requested through a valid component interface
+- **THEN** the Registry returns null
+
+#### Scenario: Existing component has the wrong type
+- **WHEN** an existing component ID is requested through a component interface its object does not implement
+- **THEN** lookup fails with `IllegalArgumentException` identifying the ID, requested interface name, and actual implementation class name
+
+#### Scenario: Query token is not a component interface
+- **WHEN** a caller supplies a concrete class, an ordinary interface, or null as a query token
+- **THEN** the Registry rejects it with the specified argument or null exception category
+
+#### Scenario: Consumer cannot administer registrations
+- **WHEN** ordinary code receives `NenjimRegistryService`
+- **THEN** that public view exposes no registration, removal, loading, resolver, class-loading, stop, permission, event, or persistence operation
+
+### Requirement: Internal registration maintains an interface index
+The internal Registry administration view SHALL remain package-private, SHALL not be a Nenjim component, and SHALL expose registration but no removal. Each registration SHALL atomically add a unique ID to a primary ID-to-object catalogue and to a secondary ordered index under every implemented interface in the recursive hierarchy that extends `NenjimComponent`. It SHALL not index concrete classes, ordinary interfaces, or the administration interface. Reads and registrations SHALL remain internally consistent when registrations occur after startup.
+
+#### Scenario: Duplicate ID is rejected
+- **WHEN** a component is registered under an ID already present in the Registry
+- **THEN** registration fails with `IllegalArgumentException` identifying the duplicated ID and both the existing and attempted implementation class names without changing either index
+
+#### Scenario: Null registration input is rejected
+- **WHEN** a registration supplies a null ID or component
+- **THEN** registration fails with `NullPointerException` without changing either index
+
+#### Scenario: Same instance receives aliases
+- **WHEN** the same object is registered under multiple different unused IDs
+- **THEN** every registration succeeds and each ID resolves to the identical object reference
+
+#### Scenario: Inherited component interfaces are indexed
+- **WHEN** a registered object implements a component interface that extends another component interface
+- **THEN** the registration ID appears under both interfaces, including inherited interfaces not directly declared by the implementation class
+
+#### Scenario: One registration exposes multiple views
+- **WHEN** one object implements multiple component interfaces and is registered once
+- **THEN** its one ID appears under every implemented component interface and typed lookups preserve reference identity
+
+#### Scenario: Registration occurs after startup
+- **WHEN** internal administration registers another component after the Registry has started
+- **THEN** subsequent queries observe a consistent registration while previously returned ID snapshots remain unchanged
+
+### Requirement: Registry startup is single-use and gates queries
+The Registry application's first `start()` call SHALL be the only accepted attempt and SHALL enable queries only after successful startup. A later attempt SHALL fail with `IllegalStateException`, including when the first attempt failed. Registration SHALL remain allowed before and after startup, and starting the Registry SHALL not construct, register, start, or stop another component.
+
+#### Scenario: Query before startup
+- **WHEN** either lookup operation is called before successful Registry startup
+- **THEN** it fails with `IllegalStateException`
+
+#### Scenario: Registry starts once
+- **WHEN** the Registry is started successfully and start is requested again
+- **THEN** the second request fails with `IllegalStateException`
+
+#### Scenario: Failed start is not retried
+- **WHEN** the first Registry start attempt fails
+- **THEN** every later start request fails with `IllegalStateException`
+
+### Requirement: Registry manager owns hardcoded composition and startup
+`NenjimRegistryServiceManager` SHALL be a Nenjim component whose only public operation is `start() throws Exception`. Its public reference implementation SHALL be a distinct `NenjimApplication` object and SHALL accept only one start attempt, including after failure. The first attempt SHALL construct and directly start one Registry object, register that object first as `nenjim.registry.service`, register the manager second as `nenjim.registry.service-manager`, construct and register the complete required hardcoded component set in dependency order, start only the explicit active application subset in dependency-safe order, announce the existing online point, and preserve the existing blocking wait.
+
+#### Scenario: Registry and manager views are registered
+- **WHEN** manager composition reaches completed registration
+- **THEN** the Registry object is retrievable by one ID as both `NenjimRegistryService` and `NenjimApplication`, the manager is retrievable by one different ID as both `NenjimRegistryServiceManager` and `NenjimApplication`, and the Registry and manager are different instances
+
+#### Scenario: Required hardcoded bindings are registered
+- **WHEN** manager composition completes
+- **THEN** all component IDs and implementation choices enumerated by issue #76 are present exactly as configured, including intentionally inactive components
+
+#### Scenario: Explicit startup subset preserves order
+- **WHEN** the manager starts applications
+- **THEN** it starts `assetaz.ticker.default`, `evelyn.service.prod`, `evelyn.service.test`, `evelyn.iou-burner.prod`, and `evelyn.mission-control.default` in that order
+
+#### Scenario: Deliberately inactive applications remain inactive
+- **WHEN** manager startup completes its explicit start sequence
+- **THEN** `jupiter-perps-alarm.default` and the currently commented Composer, Process Manager, Test Tool, Soda Task Manager, and Suwimo Client are not started
+
+#### Scenario: Manager start is not retried
+- **WHEN** any first manager start attempt has begun and start is requested again
+- **THEN** the later request fails with `IllegalStateException` whether the first attempt succeeded or failed
+
+#### Scenario: Registration does not activate components
+- **WHEN** the manager registers a component
+- **THEN** registration alone neither starts nor stops that component
+
+### Requirement: Applications own explicit dependency selection
+A non-bootstrap application or service that owns a component choice SHALL receive the public Registry view through constructor injection, express the choice as one or more explicit component IDs, and use typed lookup. A required missing or wrong-type binding SHALL fail clearly rather than selecting the first component returned for an interface. The initial Ticker composition SHALL explicitly select only `assetaz.price-source.raydium-pool.eve-usdt`; `assetaz.price-source.hardcoded` SHALL remain registered but inactive.
+
+#### Scenario: Ticker resolves its configured source
+- **WHEN** the Ticker is constructed with the public Registry and the Raydium EVE/USDT source ID
+- **THEN** it resolves that exact `PriceSource` and does not activate the hardcoded source
+
+#### Scenario: Required configured dependency is missing
+- **WHEN** an application resolves a required hardcoded component ID that is absent
+- **THEN** construction or startup fails with a diagnostic identifying the required ID and interface without exposing component secrets
+
+#### Scenario: Internal administration is not injected
+- **WHEN** an ordinary application receives its Registry dependency
+- **THEN** it receives only `NenjimRegistryService` and cannot self-register
+
+### Requirement: Main is a thin outer bootstrap
+`com.r35157.nenjim.hubd.Main` SHALL be a final non-component class that does not implement `NenjimApplication`. Its `main(String[])` SHALL construct `NenjimRegistryServiceManagerImpl` through a variable typed as `NenjimApplication` and start it. The Gradle application entry point SHALL name this class. Construction, registration, composition, and lifecycle ownership SHALL remain in `NenjimRegistryServiceManagerImpl`; the bootstrap SHALL perform none of those responsibilities beyond constructing and starting the manager.
+
+#### Scenario: Start through the outer bootstrap
+- **WHEN** the configured Java entry point is invoked
+- **THEN** `Main.main(...)` constructs one Registry manager as a Nenjim application and delegates startup to it
+
+#### Scenario: No duplicate composition path remains
+- **WHEN** the source tree is inspected after migration
+- **THEN** the old Hub interface, `com.r35157.nenjim.hubd.impl.ref.Main`, and the `NenjimHubImpl` composition implementation are absent, while `com.r35157.nenjim.hubd.Main` contains no replacement composition path
+
+### Requirement: Registry terminology and package boundaries are consistent
+Public component contracts SHALL live in `com.r35157.nenjim.component`; public Registry service contracts SHALL live in `com.r35157.nenjim.service.registry`; the component ID SHALL live in its `.valuetypes` package; and internal administration and Registry storage SHALL live in `.impl.ref`. Directly affected Ticker price-source API and implementation packages SHALL use `.pricesource` rather than `.plugins.pricesource`. Public reference-type parameters, return values, and record components added or changed by this capability SHALL declare explicit nullability.
+
+#### Scenario: Ticker source packages are inspected
+- **WHEN** source packages and imports are searched after migration
+- **THEN** no directly affected Ticker price-source package uses the `plugins` segment
+
+#### Scenario: Internal Registry administration is inspected
+- **WHEN** an ordinary consumer compiles against the public Registry packages
+- **THEN** the package-private administration interface and Registry implementation are inaccessible
+
+### Requirement: Deferred runtime features remain absent
+The Registry SHALL represent one catalogue of already constructed components and SHALL not implement Contexts, artifact-version identity, resolution, classloading, automatic discovery, contributor APIs, public runtime loading or registration, removal, persistence, events, subscribers, user configuration, automatic selection, automatic start-all, ownership tracking, usage counts, permissions, scopes, filtered views, or a common stop lifecycle.
+
+#### Scenario: Consumer inspects the first Registry API
+- **WHEN** a consumer examines the public Registry and manager contracts
+- **THEN** only the agreed read-only lookup and manager start operations are available and no deferred feature is exposed

+## 1. Component and Registry Foundation
+
+- [x] 1.1 Add the marker/application contracts, validated component ID, and public read-only Registry/service-manager interfaces with explicit nullability.
+- [x] 1.2 Implement the package-private Registry administration and synchronized Registry service with primary storage, recursive ordered interface indexing, typed lookup, immutable snapshots, and single-use startup.
+- [x] 1.3 Mark every required registered query interface as a Nenjim component and each registered no-argument lifecycle implementation as a Nenjim application without introducing a common stop API.
+
+## 2. Composition and Migration
+
+- [x] 2.1 Rename the directly affected Ticker price-source packages and imports from `.plugins.pricesource` to `.pricesource`.
+- [x] 2.2 Replace the Ticker's temporary source-instance constructor with public Registry injection plus explicit source component IDs and clear required-dependency failures.
+- [x] 2.3 Implement the public Registry service manager as the sole hardcoded composition root with every required component ID and implementation registered in dependency order.
+- [x] 2.4 Preserve the explicit five-application startup order, deliberately inactive components, online message, blocking wait, and single-use manager lifecycle.
+- [x] 2.5 Replace the old Hub interface and `com.r35157.nenjim.hubd.impl.ref.Main`/`NenjimHubImpl` composition path with the thin `com.r35157.nenjim.hubd.Main` bootstrap, update every runtime entry point, and keep composition and lifecycle ownership in the Registry manager.

 ### Requirement: Price sources are discovered and lifecycle-managed
-Nenjim SHALL be able to construct each price source independently in an initialized but unstarted state without supplying a ticker or sink.

Source names SHALL be non-empty safe directory components and SHALL reject `/`, `\`, `..`, and control characters without rewriting them. A source SHALL announce typed prices and timestamps only through the sink received at start and SHALL remain unaware of its persistence path. A repeated source start SHALL reject the call before replacing its existing sink.
+Nenjim SHALL be able to construct and register each price source independently in an initialized but unstarted state without supplying a ticker or sink. The ticker SHALL receive the public Nenjim Registry through constructor injection and resolve its explicitly configured `PriceSource` component IDs, while ordinary ticker clients SHALL NOT receive a public operation for adding or managing sources.

+# nenjim-component-registry Specification
+
+## Purpose
+
+Provide one typed, read-only catalogue of constructed Nenjim components and a lifecycle manager that owns the current hardcoded composition without introducing Context or dynamic-loading semantics.
+
+## Requirements
+
+### Requirement: Components and applications have minimal common contracts
+`NenjimComponent` SHALL be a pure marker with no component-ID property. `NenjimApplication` SHALL extend `NenjimComponent` and expose only `start() throws Exception` as its common lifecycle operation. Domain service interfaces SHALL remain focused on their domain APIs, while a concrete service implementation with a no-argument active start lifecycle SHALL additionally implement `NenjimApplication`.
+
+#### Scenario: One object has more than one registration identity
+- **WHEN** the same component object is registered under two different unused component IDs
+- **THEN** both IDs identify the same object because IDs are Registry metadata rather than object properties
+
+#### Scenario: A service implementation is startable
+- **WHEN** a service implementation has a no-argument active start lifecycle
+- **THEN** the implementation is discoverable as `NenjimApplication` without adding lifecycle operations solely to its domain service interface
+
+#### Scenario: Common stop is unavailable
+- **WHEN** a caller uses `NenjimApplication`
+- **THEN** the contract exposes no common stop operation
+
+### Requirement: Component IDs are canonical validated values
+`NenjimComponentId` SHALL reject null, strip surrounding Unicode whitespace before storage and validation, and accept only lower-case ASCII dot-separated segments whose first character is a letter and whose remaining subparts contain lower-case letters or digits separated by single internal hyphens. Standard record value equality and hashing SHALL define ID equality.
+
+#### Scenario: Surrounding whitespace is canonicalized
+- **WHEN** an ID is constructed from `   nenjim.registry.service   `
+- **THEN** its stored value is `nenjim.registry.service`
+
+#### Scenario: Valid component IDs are accepted
+- **WHEN** IDs such as `nenjim.registry.service`, `assetaz.price-source.raydium-pool`, or `evelyn.service.prod` are constructed
+- **THEN** construction succeeds
+
+#### Scenario: Invalid component IDs are rejected
+- **WHEN** an ID is null or contains uppercase letters, underscores, internal whitespace, an empty segment, a leading or trailing dot, or a malformed hyphen
+- **THEN** construction fails with the specified null or argument exception category and identifies the invalid canonicalized value without exposing secrets
+
+### Requirement: Registry consumers receive only typed read-only lookup
+`NenjimRegistryService` SHALL be a Nenjim component and SHALL expose exactly an ordered-ID lookup by component interface and a nullable typed lookup by component ID and expected component interface. Both operations SHALL reject null arguments. A query type SHALL be an interface extending `NenjimComponent`; concrete classes and ordinary interfaces SHALL be rejected.
+
+#### Scenario: List matching component IDs
+- **WHEN** a caller requests the IDs for a valid component interface
+- **THEN** the Registry returns all registrations indexed under that interface in registration order as an immutable snapshot that is not changed by later registrations
+
+#### Scenario: No component implements an interface
+- **WHEN** a valid component interface has no indexed registration
+- **THEN** the Registry returns an empty immutable list rather than null
+
+#### Scenario: Retrieve a matching component
+- **WHEN** an existing component ID is requested through an interface implemented by its object
+- **THEN** the Registry returns that object cast to the requested interface
+
+#### Scenario: Component ID is missing
+- **WHEN** an unused component ID is requested through a valid component interface
+- **THEN** the Registry returns null
+
+#### Scenario: Existing component has the wrong type
+- **WHEN** an existing component ID is requested through a component interface its object does not implement
+- **THEN** lookup fails with `IllegalArgumentException` identifying the ID, requested interface name, and actual implementation class name
+
+#### Scenario: Query token is not a component interface
+- **WHEN** a caller supplies a concrete class, an ordinary interface, or null as a query token
+- **THEN** the Registry rejects it with the specified argument or null exception category
+
+#### Scenario: Consumer cannot administer registrations
+- **WHEN** ordinary code receives `NenjimRegistryService`
+- **THEN** that public view exposes no registration, removal, loading, resolver, class-loading, stop, permission, event, or persistence operation
+
+### Requirement: Internal registration maintains an interface index
+The internal Registry administration view SHALL remain package-private, SHALL not be a Nenjim component, and SHALL expose registration but no removal. Each registration SHALL atomically add a unique ID to a primary ID-to-object catalogue and to a secondary ordered index under every implemented interface in the recursive hierarchy that extends `NenjimComponent`. It SHALL not index concrete classes, ordinary interfaces, or the administration interface. Reads and registrations SHALL remain internally consistent when registrations occur after startup.
+
+#### Scenario: Duplicate ID is rejected
+- **WHEN** a component is registered under an ID already present in the Registry
+- **THEN** registration fails with `IllegalArgumentException` identifying the duplicated ID and both the existing and attempted implementation class names without changing either index
+
+#### Scenario: Null registration input is rejected
+- **WHEN** a registration supplies a null ID or component
+- **THEN** registration fails with `NullPointerException` without changing either index
+
+#### Scenario: Same instance receives aliases
+- **WHEN** the same object is registered under multiple different unused IDs
+- **THEN** every registration succeeds and each ID resolves to the identical object reference
+
+#### Scenario: Inherited component interfaces are indexed
+- **WHEN** a registered object implements a component interface that extends another component interface
+- **THEN** the registration ID appears under both interfaces, including inherited interfaces not directly declared by the implementation class
+
+#### Scenario: One registration exposes multiple views
+- **WHEN** one object implements multiple component interfaces and is registered once
+- **THEN** its one ID appears under every implemented component interface and typed lookups preserve reference identity
+
+#### Scenario: Registration occurs after startup
+- **WHEN** internal administration registers another component after the Registry has started
+- **THEN** subsequent queries observe a consistent registration while previously returned ID snapshots remain unchanged
+
+### Requirement: Registry startup is single-use and gates queries
+The Registry application's first `start()` call SHALL be the only accepted attempt and SHALL enable queries only after successful startup. A later attempt SHALL fail with `IllegalStateException`, including when the first attempt failed. Registration SHALL remain allowed before and after startup, and starting the Registry SHALL not construct, register, start, or stop another component.
+
+#### Scenario: Query before startup
+- **WHEN** either lookup operation is called before successful Registry startup
+- **THEN** it fails with `IllegalStateException`
+
+#### Scenario: Registry starts once
+- **WHEN** the Registry is started successfully and start is requested again
+- **THEN** the second request fails with `IllegalStateException`
+
+#### Scenario: Failed start is not retried
+- **WHEN** the first Registry start attempt fails
+- **THEN** every later start request fails with `IllegalStateException`
+
+### Requirement: Registry manager owns hardcoded composition and startup
+`NenjimRegistryServiceManager` SHALL be a Nenjim component whose only public operation is `start() throws Exception`. Its public reference implementation SHALL be a distinct `NenjimApplication` object and SHALL accept only one start attempt, including after failure. The first attempt SHALL construct and directly start one Registry object, register that object first as `nenjim.registry.service`, register the manager second as `nenjim.registry.service-manager`, construct and register the complete required hardcoded component set in dependency order, start only the explicit active application subset in dependency-safe order, announce the existing online point, and preserve the existing blocking wait.
+
+#### Scenario: Registry and manager views are registered
+- **WHEN** manager composition reaches completed registration
+- **THEN** the Registry object is retrievable by one ID as both `NenjimRegistryService` and `NenjimApplication`, the manager is retrievable by one different ID as both `NenjimRegistryServiceManager` and `NenjimApplication`, and the Registry and manager are different instances
+
+#### Scenario: Required hardcoded bindings are registered
+- **WHEN** manager composition completes
+- **THEN** all component IDs and implementation choices enumerated by issue #76 are present exactly as configured, including intentionally inactive components
+
+#### Scenario: Explicit startup subset preserves order
+- **WHEN** the manager starts applications
+- **THEN** it starts `assetaz.ticker.default`, `evelyn.service.prod`, `evelyn.service.test`, `evelyn.iou-burner.prod`, and `evelyn.mission-control.default` in that order
+
+#### Scenario: Deliberately inactive applications remain inactive
+- **WHEN** manager startup completes its explicit start sequence
+- **THEN** `jupiter-perps-alarm.default` and the currently commented Composer, Process Manager, Test Tool, Soda Task Manager, and Suwimo Client are not started
+
+#### Scenario: Manager start is not retried
+- **WHEN** any first manager start attempt has begun and start is requested again
+- **THEN** the later request fails with `IllegalStateException` whether the first attempt succeeded or failed
+
+#### Scenario: Registration does not activate components
+- **WHEN** the manager registers a component
+- **THEN** registration alone neither starts nor stops that component
+
+### Requirement: Applications own explicit dependency selection
+A non-bootstrap application or service that owns a component choice SHALL receive the public Registry view through constructor injection, express the choice as one or more explicit component IDs, and use typed lookup. A required missing or wrong-type binding SHALL fail clearly rather than selecting the first component returned for an interface. The initial Ticker composition SHALL explicitly select only `assetaz.price-source.raydium-pool.eve-usdt`; `assetaz.price-source.hardcoded` SHALL remain registered but inactive.
+
+#### Scenario: Ticker resolves its configured source
+- **WHEN** the Ticker is constructed with the public Registry and the Raydium EVE/USDT source ID
+- **THEN** it resolves that exact `PriceSource` and does not activate the hardcoded source
+
+#### Scenario: Required configured dependency is missing
+- **WHEN** an application resolves a required hardcoded component ID that is absent
+- **THEN** construction or startup fails with a diagnostic identifying the required ID and interface without exposing component secrets
+
+#### Scenario: Internal administration is not injected
+- **WHEN** an ordinary application receives its Registry dependency
+- **THEN** it receives only `NenjimRegistryService` and cannot self-register
+
+### Requirement: Main is a thin outer bootstrap
+`com.r35157.nenjim.hubd.Main` SHALL be a final non-component class that does not implement `NenjimApplication`. Its `main(String[])` SHALL construct `NenjimRegistryServiceManagerImpl` through a variable typed as `NenjimApplication` and start it. The Gradle application entry point SHALL name this class. Construction, registration, composition, and lifecycle ownership SHALL remain in `NenjimRegistryServiceManagerImpl`; the bootstrap SHALL perform none of those responsibilities beyond constructing and starting the manager.
+
+#### Scenario: Start through the outer bootstrap
+- **WHEN** the configured Java entry point is invoked
+- **THEN** `Main.main(...)` constructs one Registry manager as a Nenjim application and delegates startup to it
+
+#### Scenario: No duplicate composition path remains
+- **WHEN** the source tree is inspected after migration
+- **THEN** the old Hub interface, `com.r35157.nenjim.hubd.impl.ref.Main`, and the `NenjimHubImpl` composition implementation are absent, while `com.r35157.nenjim.hubd.Main` contains no replacement composition path
+
+### Requirement: Registry terminology and package boundaries are consistent
+Public component contracts SHALL live in `com.r35157.nenjim.component`; public Registry service contracts SHALL live in `com.r35157.nenjim.service.registry`; the component ID SHALL live in its `.valuetypes` package; and internal administration and Registry storage SHALL live in `.impl.ref`. Directly affected Ticker price-source API and implementation packages SHALL use `.pricesource` rather than `.plugins.pricesource`. Public reference-type parameters, return values, and record components added or changed by this capability SHALL declare explicit nullability.
+
+#### Scenario: Ticker source packages are inspected
+- **WHEN** source packages and imports are searched after migration
+- **THEN** no directly affected Ticker price-source package uses the `plugins` segment
+
+#### Scenario: Internal Registry administration is inspected
+- **WHEN** an ordinary consumer compiles against the public Registry packages
+- **THEN** the package-private administration interface and Registry implementation are inaccessible
+
+### Requirement: Deferred runtime features remain absent
+The Registry SHALL represent one catalogue of already constructed components and SHALL not implement Contexts, artifact-version identity, resolution, classloading, automatic discovery, contributor APIs, public runtime loading or registration, removal, persistence, events, subscribers, user configuration, automatic selection, automatic start-all, ownership tracking, usage counts, permissions, scopes, filtered views, or a common stop lifecycle.
+
+#### Scenario: Consumer inspects the first Registry API
+- **WHEN** a consumer examines the public Registry and manager contracts
+- **THEN** only the agreed read-only lookup and manager start operations are available and no deferred feature is exposed
