A second Copilot gateway example: GPT-6 Luna for everything, with the whole profile v3.

• examples/copilot-api-gateway/srcmorph-luna.yaml
  • Every file, every package and the project go to gpt-6-luna through the GitHub Copilot API Gateway.
  • One rule per kind of source, each with its prompt and its exact fact counters: Java, SQL, shell, Perl, POM (priority 10) and XML. The fallback rule takes every other file; profile v3 has no counters for those.
  • Every rule uses onOversize: mapReduce with map-chunk and reduce-parts, the package and project rules too (their default, fail, would stop the run on a package whose summaries exceed the window). Any input larger than the window is read chunk by chunk and never sampled (MODEL-CARD finding 7: Luna names every planted middle name).
  • contextSize: 120000, as in the measured gateway run.
  • subtrees: "." without target/, so the root pom.xml is indexed too.
  • It starts with command: Plan; then All.
• ExamplesConfigBindingTest
  • Pins that every rule, package and project included, routes to Luna and uses mapReduce, and that every rule except the fallback names a facts file of the profile.
  • Also pins that the map and reduce prompts resolve and that stream and the loopback baseUrl hold.
• docs/copilot-api-gateway.md: points to the new file. It also showed maxOutputTokens: 2048 for the existing example, which has 4096.

Checked

• With the srcmorph 1.4.0 jar (build-your-own-jar), Plan and Check pass on the language corpus, the card corpus and srcmorph-maven-plugin. Every phase was in order, nothing was sent and nothing was written.
• ExamplesConfigBindingTest: 8/8 green. A wrong factsKey turns the new test red.
• Spotless and REUSE are clean.
• Not run: a real index run through the gateway.

The big-pom and huge-pom rules of the self-test and build-your-own-jar keep file-body-fallback. That is deliberate (profiles/README.md, TODO D3: no large POM measured), so it is unchanged here.

Walkthrough

The pull request adds a GPT-6 Luna configuration for the Copilot API Gateway example. It defines project, package, and source rules, updates the guide and changelog, and adds a test that checks the configuration and prompt references.

Changes: Luna gateway example

Layer / File(s)	Summary
Project scope and model settings examples/copilot-api-gateway/srcmorph-luna.yaml	Configures indexed project paths, the openai-compatible provider, the profile directory, and the Luna model settings.
Generation rules and validation examples/copilot-api-gateway/srcmorph-luna.yaml, docs/copilot-api-gateway.md, CHANGELOG.md, srcmorph-cli/src/test/java/net/ladenthin/srcmorph/cli/ExamplesConfigBindingTest.java	Adds package, project, and source-generation rules with mapReduce handling for oversized inputs. Documents both configurations and corrects the documented maxOutputTokens value to 4096. Tests model settings, rule routing, prompt references, and fact files.

Full details: Title check

Explanation

The title names the primary change: a new GPT-6 Luna example routed through the Copilot API Gateway, using the whole project profile v3. The changeset adds srcmorph-luna.yaml, a Luna routing test, and docs for that example, so the title matches the main change. It also covers the profile scope. It does not mention the maxOutputTokens correction in the docs, which is a minor secondary change.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Route generic CGI files to the fallback.

A .cgi file can contain Python or shell code. This rule sends it to the Perl prompt and applies Perl fact counters, so its summary uses the wrong language. Remove .cgi from this condition while keeping it in fileExtensions, or route it by language. (raw.githubusercontent.com)

Describe the extension limit.

The configuration indexes only the extensions in fileExtensions. For example, .js and .ts files are omitted rather than sent to the fallback. State this limit here so users do not assume the project index covers those files. (raw.githubusercontent.com)

Include reduce requests in the quota description.

An oversized input needs a request for each chunk and at least one additional request to combine multiple partial summaries. The current wording can cause users to underestimate their Copilot quota usage. (raw.githubusercontent.com)
