+These hooks are invoked via OpenAPI Generator's `--enable-post-process-file` option. They stay deterministic and offline-friendly:
 
 - Normalise line endings to LF and strip trailing whitespace.
 - Preserve file mode 0644.
 - Inject a deterministic banner for supported languages (TS/JS/Go/Java/C#/Python/Ruby) when enabled (default on).
-- Language-specific rewrites (auth/retry/pagination/telemetry) will be added as SDKGEN-62-002 progresses.
+- Copy shared SDK helpers (auth, retries, pagination, telemetry) per language into the generated output when `STELLA_POSTPROCESS_ROOT` and `STELLA_POSTPROCESS_LANG` are provided. TypeScript/Python exports are auto-wired so helpers are available from the package barrel.
 
 ## Usage
 
@@ -22,15 +22,30 @@ Or pass via CLI where supported:
 --global-property "postProcessFile=$PWD/postprocess/postprocess.sh"

+
 ## Determinism
 - Uses only POSIX tools (`sed`, `perl`) available in build containers.
 - Does not reorder content; only whitespace/line-ending normalization.
 - Safe to run multiple times (idempotent).
 
 ## Configuration (optional)
-- `STELLA_POSTPROCESS_ADD_BANNER` (default `1`): when enabled, injects `Generated by StellaOps SDK generator — do not edit.` at the top of supported source files, idempotently.
-- Future flags (placeholders until implemented): `STELLA_POSTPROCESS_ENABLE_AUTH`, `STELLA_POSTPROCESS_ENABLE_RETRY`, `STELLA_POSTPROCESS_ENABLE_PAGINATION`, `STELLA_POSTPROCESS_ENABLE_TELEMETRY`.
+- `STELLA_POSTPROCESS_ADD_BANNER` (default `1`): injects `Generated by StellaOps SDK generator — do not edit.` at the top of supported source files, idempotently.

+- `STELLA_POSTPROCESS_LANG`: one of `ts|python|go|java|csharp|ruby`; controls which helper set is copied.
+
+## Helper contents (per language)
+- **TypeScript** (`templates/typescript/sdk-hooks.ts`, `sdk-error.ts`, package/tsconfig templates, README): fetch composers for auth, retries, telemetry headers, paginator, and a minimal typed error class. Packaging files provide ESM/CJS outputs with deterministic settings.
+- **Python** (`templates/python/sdk_hooks.py`): transport-agnostic wrappers for auth, retries, telemetry headers, and cursor pagination.
+- **Go** (`templates/go/hooks.go`): http.RoundTripper helpers for auth, telemetry, retries, and a generic paginator.
+- **Java** (`templates/java/Hooks.java`): OkHttp interceptors for auth, telemetry, retries, plus a helper to compose them.
+- C#/Ruby templates are reserved for follow-on language tracks; the banner logic already supports them.
 
 ## Next steps
-- Add language-specific post steps (auth helper injection, retry/pagination utilities, telemetry headers) behind flags per language template.
-- Wire into CI to enforce post-processed trees are clean.
+- Add C#/Ruby helpers once those language tracks start.

+
+Generated client for StellaOps APIs. This package is produced deterministically via the SDK generator.
+
+## Build
+
+```
+npm install
+npm run build
+```
+
+## Usage (sketch)
+
+```ts
+import { DefaultApi, ApiConfig, composeFetch, withAuth, withTelemetry } from "@stellaops/sdk";
+
+const fetchWithHooks = composeFetch(
+  f => withAuth(f, { token: process.env.STELLA_TOKEN }),

+);
+
+const api = new DefaultApi(new ApiConfig({ basePath: "https://gateway.local/api", fetchApi: fetchWithHooks }));
+const resp = await api.ping();
+console.log(resp.message);
+```

+Deterministic generator settings for the Python SDK (asyncio library).
+
+## Prereqs
+- `STELLA_OAS_FILE` pointing to the frozen OpenAPI spec.
+- OpenAPI Generator CLI 7.4.0 jar at `tools/openapi-generator-cli-7.4.0.jar` (override with `STELLA_OPENAPI_GENERATOR_JAR`).
+- JDK 21 available on PATH (vendored at `../tools/jdk-21.0.1+12`; set `JAVA_HOME` if needed).
+
+## Generate
+```bash
+cd src/Sdk/StellaOps.Sdk.Generator
+STELLA_OAS_FILE=ts/fixtures/ping.yaml \
+STELLA_SDK_OUT=$(mktemp -d) \
+python/generate-python.sh
+```
+
+Outputs land in `out/python/` and are post-processed to normalize whitespace, inject the banner, and copy shared helpers (`sdk_hooks.py`).
+Override `STELLA_SDK_OUT` to keep the repo clean during local runs.

+# TypeScript SDK (SDKGEN-63-001)
+
+This directory contains deterministic generator settings for the TypeScript SDK.
+
+## Prereqs
+- OpenAPI spec file path exported as `STELLA_OAS_FILE` (temporary until APIG0101 publishes the canonical spec).
+- OpenAPI Generator CLI 7.4.0 jar at `tools/openapi-generator-cli-7.4.0.jar` or override `STELLA_OPENAPI_GENERATOR_JAR`.
+- JDK 21 available on PATH (vendored at `../tools/jdk-21.0.1+12`; set `JAVA_HOME` accordingly).
+
+## Generate
+
+```bash
+cd src/Sdk/StellaOps.Sdk.Generator
+STELLA_OAS_FILE=/path/to/api.yaml \
+STELLA_SDK_OUT=$(mktemp -d) \
+STELLA_OPENAPI_GENERATOR_JAR=tools/openapi-generator-cli-7.4.0.jar \
+ts/generate-ts.sh
+```
+
+Outputs land in `out/typescript/` and are post-processed to:
+- Normalize whitespace/line endings.
+- Inject traceability banner.
+- Copy shared helpers (`sdk-hooks.ts`) and wire them through the package barrel.
+
+To validate the pipeline locally with a tiny fixture spec (`ts/fixtures/ping.yaml`), run:
+
+```bash
+cd src/Sdk/StellaOps.Sdk.Generator/ts
+./test_generate_ts.sh   # skips if the generator jar is absent
+```
+
+## Notes
+- README/package.json are suppressed in generator output; Release pipeline provides deterministic packaging instead.
+- Global properties disable model/api docs/tests to keep the alpha lean and deterministic.
+- Helper wiring depends on `STELLA_POSTPROCESS_ROOT`/`STELLA_POSTPROCESS_LANG` being set by the script.
+- Override output directory via `STELLA_SDK_OUT` to avoid mutating the repo during local tests.
