fix(oracle): match .slnx solutions + deepen shallow clone so Infer# can build

[PhysShell]

Two build-blockers the first real Dapper run exposed

The first dispatch of oracle (cross-tool) on DapperLib/Dapper (run 27660966107) got CodeQL + own-check running, but the Infer# build failed, so the comparison stayed CodeQL-only. Two distinct causes, both fixed:

1. Dapper's solution is Dapper.slnx, not .sln

Dapper moved to the newer XML solution format (Dapper.slnx). The auto-detect's find -name '*.sln' didn't match it → note: 0 root / 0 total → dir fallback → MSB1050 (root has multiple projects).

→ Auto-detect now matches both *.sln and *.slnx.

2. Shallow clone breaks Nerdbank.GitVersioning

Even with the solution named explicitly (build: Dapper.slnx), the build died in nbgv:

error MSB4018: Nerdbank.GitVersioning.GitException: Shallow clone lacks the objects
required to calculate version height. ... commit ... could not be found.

We clone the target --depth 1, but nbgv (which Dapper uses to compute its version at build time) walks git history.

→ Before building, deepen the clone: git -C target fetch --unshallow --tags (guarded with || true — harmless when already complete). CodeQL + own-check are unaffected (they read source, no build).

Docs

docs/notes/oracle.md updated: .slnx is recognised, and the shallow clone is deepened for version tools like nbgv.

Honest note

Building arbitrary third-party repos for Infer# is inherently fragile (SDK pins, restore, custom targets); that's why the build step is continue-on-error with a partial report. These two fixes clear the specific blockers Dapper hit — a common stack (.slnx + nbgv), so they should generalise.

Verified

oracle.yml valid YAML · build-step bash parses · .slnx root-match check passes · no comparator change (--selftest still 12/12).

After merge

Re-dispatch oracle (cross-tool), repo = DapperLib/Dapper, no build input — Dapper.slnx is auto-picked and the deepened clone lets nbgv compute the version.

📝 Walkthrough

Walkthrough

The oracle workflow's Infer# build-target logic is updated to match both .sln and .slnx files and to prefer a unique root-level solution before scanning the target directory. A failure-tolerant git fetch --unshallow --tags step is added before building. Documentation is updated to reflect these changes.

Changes

Infer# Build Target Selection and Shallow Clone Deepening

Layer / File(s)	Summary
Infer# solution selection and unshallow fetch .github/workflows/oracle.yml, docs/notes/oracle.md	Solution file matching is broadened to include .slnx, root-level unique solution is preferred before falling back to a directory scan, the ambiguity note message is revised, and a quiet failure-tolerant git fetch --unshallow --tags step is added before building. Documentation is updated to describe the new selection priority and the shallow clone deepening step.

Poem

🐇 A .slnx was lost in the tree,
But the rabbit sniffed root — "Ah-ha, that is thee!"
Unshallow the clone, let the tags flow free,
For versioning tools need their full history.
Hop hop, the build runs as neat as can be! 🌿
