Subject: [PATCH 01/11] feat: add JSON logging format for production
 deployments

Support JSON output format in addition to text format for better log aggregation
and parsing in production environments. JSON logs include timestamp, level, message,
optional context (for child loggers), and optional metadata. Format can be configured
via LoggerConfig or LOG_FORMAT environment variable.

All 13 logger tests pass, covering both text and JSON formats.

Subject: [PATCH 03/11] feat: add injectable logger pattern for library code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Library is now silent by default. Consumers can inject their own logger
via SingleAgentClientConfig.logger to see internal diagnostics.

Changes:
- Add ILogger interface and noopLogger for dependency injection
- Update SingleAgentClient, TaskExecutor, AsyncHandler to accept logger
- Update ConfigurationManager static methods to accept optional logger
- Remove all console.log/warn/error from library code
- Export ILogger, noopLogger, LogFormat from main index

 LoggerConfig
MIME-Version: 1.0

Library API now accepts a LoggerConfig object instead of requiring
consumers to create their own ILogger instance. Default is
{ level: 'warn' } so warnings and errors are visible but debug/info
noise is hidden.

Before:
  const client = new AdCPClient(agents, {
    logger: createLogger({ level: 'debug', format: 'json' })
  });

After:
  const client = new AdCPClient(agents, {
    logging: { level: 'debug', format: 'json' }
  });

- Simplify getAuthToken() to only return direct tokens
- Update error-scenarios tests to match PR #78 implementation:
  - working/input-required are valid intermediate states, not errors
  - Add strictSchemaValidation: false for mock responses
- Partially fix handler-controlled-flow tests:
  - Fix autoApproveHandler assertion (returns true, not string)
  - Fix deferAllHandler assertion (deferred is valid state)
- Update auth tests to reflect silent library behavior

From: Brian O'Kelley <bokelley@scope3.com>
Date: Sat, 13 Dec 2025 11:09:22 -0500
Subject: [PATCH 08/11] fix: propagate inputHandler through multi-round
 conversations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TaskExecutor bug fix:
- continueTaskWithInput now accepts and passes inputHandler parameter
- handleInputRequired passes inputHandler when continuing task
- Fixes handler-controlled flow tests that rely on multi-round input

Test fixes:
- Add contextId to mock input-required responses
- Fix inputCount logic in createFieldHandler test
- Fix data assertion nesting (result.data?.result || result.data)
- Change handler error test to check result.error instead of rejection
- Remove CI skip from handler-controlled-flow tests (all 13 tests pass)
- Simplify field history test to not depend on unimplemented features

-**BREAKING**: Remove `auth_token_env` from `AgentConfig`. Use `auth_token` directly instead.
+**JSON Logging**: Add `format: 'json'` option to logger for structured JSON output with timestamp, level, message, context, and metadata fields.
 
-Before:
 ```typescript
-{ auth_token_env: 'MY_TOKEN_ENV_VAR' }  // looked up from process.env
-```
+import { createLogger } from '@adcp/client';
 
-After:
-```typescript
-{ auth_token: process.env.MY_TOKEN_ENV_VAR }  // caller handles env lookup
+const logger = createLogger({ level: 'debug', format: 'json' });
+// Output: {"timestamp":"2025-12-13T...","level":"info","message":"...","context":"...","meta":{}}
 ```
 
-**JSON Logging**: Configure logging via `createLogger({ format: 'json' })` to output structured JSON logs with timestamp, level, message, context, and metadata.
-
-**Injectable Logger**: Library defaults to `{ level: 'warn' }` - warnings and errors are visible, but debug/info noise is hidden. Configure via the `logging` option:
-
-```typescript
-import { createLogger, AdCPClient } from '@adcp/client';
-
-const client = new AdCPClient(agents, {
-  logging: { level: 'debug', format: 'json' }
-});
-```
+**Injectable Logger Interface**: New `ILogger` interface for dependency injection and `noopLogger` singleton for silent library defaults.
 
 New exports: `ILogger`, `noopLogger`, `LogFormat`

 TaskExecutor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add logger option to SingleAgentClientConfig interface
- Wire logger from SingleAgentClient to TaskExecutor
- Add logging for task execution (debug), response status (debug),
  task completion (info), task errors (warn/error)
- Update changeset with accurate usage example
