24-29:⚠️ Potential issue | 🟠 MajorThis is a functional change, not documentation-only.
The PR objective states “no functional changes,” but this introduces new application bootstrap and dynamic route registration behavior. Please either split docs vs behavior into separate PRs or update the PR scope and add regression coverage for startup/route registration.
Also applies to: 125-158

143-152:⚠️ Potential issue | 🟠 MajorUse multi-binding (Set) pattern instead of container introspection for controller discovery.
The current
findControllers()implementation useskodein.container.tree.bindings.keyswith type-only resolution (kodein.Instance(bind.type)), which breaks with tagged or contextual controller bindings. The container introspection API is documented as "advanced knowledge" (debugging-oriented) rather than a stable discovery mechanism. Instead, bind controllers as aSet<KodeinController>during DI configuration and inject the complete set at startup—this properly handles tagged, contextual, and factory bindings.🤖 Prompt for AI Agents

Inline comments:
In `@di-kodein-advanced/README.md`:
- Around line 25-35: The fenced code blocks showing the example URLs (the blocks
containing "http://localhost:8080/users" and
"http://localhost:8080/users/{name}") need language identifiers to satisfy
markdownlint MD040; update each triple-backtick fence to use the text language
(i.e., replace ``` with ```text for both URL blocks) so the README markdown
lints cleanly.

- Around line 24-29: The change replaces the previous static bootstrap with a
new runtime bootstrap (main -> embeddedServer(Netty, port = 8080) {
kodeinApplication { application -> advancedApplication(application) } }) which
alters application startup and dynamic route registration behavior (see main,

- Around line 143-152: The findControllers function is using container
introspection (kodein.container.tree.bindings.keys and
kodein.Instance(bind.type)) which fails for tagged/contextual bindings; replace
this discovery by registering controllers into a multi-binding Set at DI
configuration (use bindSet/add or the Kodein multi-bind API to bind each
controller into a Set<KodeinController>) and then inject that
Set<KodeinController> at startup instead of calling findControllers; remove or
stop using kodein.container.tree and kodein.Instance(bind.type) in
findControllers and instead obtain the controllers via the DI-provided
Set<KodeinController> (e.g., the injected set from the DI container).

This PR improves inline documentation and README clarity in the
di-kodein-advanced sample.
No functional changes were introduced.
The goal is to make the sample easier to understand for new users
exploring dependency injection with Kodein in Ktor.
