Prefer import-aware superclass FQN when JDT binding mis-resolves.

Fix inherited static-block map expansion across compilation units by resolving superclass types from imports when binding points at the wrong package.

 ## Usage
 
+Analysis is **source-first**: the exporter reads project source and build metadata (`pom.xml`, `settings.gradle`) statically. It does **not** run Maven or Gradle against the project being analyzed.
+
 ### 1. Extract Metadata (JSON)
 ```bash
 ./gradlew :state_machine_exporter:run --args="-i ./my-project -o ./out -f json"
 ```
 
+Common options:
+
+| Flag | Description |
+|------|-------------|
+| `-i, --input` | Project directory to scan (defaults to `.`) |
+| `-j, --json` | Re-render from an existing JSON export instead of scanning source |
+| `-o, --output` | Output directory (default `./out`) |
+| `-f, --format` | Comma-separated formats: `json`, `dot`, `puml`, `scxml` |
+| `-p, --profiles` | Spring profiles for property placeholder resolution |
+| `--event`, `--state` | Enum formatting: `fn` (default), `fqn`, `sn` |
+| `--debug` | Verbose analysis logging and unresolved chain diagnostics |
+| `--no-diamonds` | Render choice/junction states as regular nodes (default: diamonds) |
+| `--include-generated-sources` | Also scan `target/` / `build/` generated `.java` trees (default: on) |
+| `--no-inline-accessors` | Disable accessor indexing/inlining (enabled by default) |
+
 ### 2. Generate Interactive Portal (HTML)
 ```bash
 ./gradlew :state_machine_exporter_html:run --args="-i ./my-project -o ./out_html"
 ```
-*Supports `--profiles prod` to resolve Spring property placeholders.*
+
+HTML-specific options:
+
+| Flag | Description |
+|------|-------------|
+| `-f, --flows` | Custom `flows.json` path |
+| `-m, --machine` | Export only machines whose name contains this filter |
+| `--open` | Open the generated portal in the default browser |
+| `--no-metadata-pane` | Hide the left metadata pane (entry points, flows) |
+| `--no-diamonds` | Render choice pseudostates as normal nodes |
+| `--debug` | Same diagnostic mode as the core exporter |
+| `--include-generated-sources` | Same generated-source scanning as the core exporter |
+| `--no-inline-accessors` | Disable accessor indexing/inlining (enabled by default) |
+| `-p, --profiles` | Spring profiles for property resolution |

+Event-only strings remain supported but do not highlight in the HTML explorer unless paired with a source state. Use `{source, event}` objects for precise transition highlighting.
+
 ## JSON Structure
 - `metadata.entryPoints`: REST, WebFlux, and JMS entry points.
 - `metadata.callChains`: Trace from API call to machine trigger (`sendEvent`).
 - `transitions.actions[].internalLogic`: Extracted source code/lambdas.
 - `metadata.properties`: Dictionary of all detected Spring profiles.
+
+## Static analysis: accessor inlining
+
+During scan, the exporter builds an **accessor index** of trivial getters, setters, record components, and constant-returning methods. At analysis time, `AccessorResolver` uses this index first (O(1) lookup), then falls back to constructor/field tracing and method-body evaluation.
+
+This improves resolution of DTO/event chains such as `request.getPayload().getType()` without running Maven or Gradle on the target project.
+
+```bash
+# Enabled by default; disable for debugging or A/B comparison
+./gradlew :state_machine_exporter:run --args="-i ./my-project -o ./out --no-inline-accessors"
+```
+
+Pipeline components live under `analysis/pipeline/` (`AccessorResolver`, `ResolutionBudget`, `MethodInvocationUnwrapper`, `FieldInitializerFinder`, `LibraryUnwrapRegistry`).
