bug-1966: apiserver swagger generation fails on hosts.go models.Error; published swagger is a stale stub

Description

Observed: (source reading; follow-up of the 2026-10-10 P0 fixes (bug-1936..1957)) swag init -g cmd/main.go fails: ParseComment error in controllers/hosts.go for comment: '// @Failure 400 {object} models.Error': cannot find type definition: models.Error. docs/swagger.yaml is a 212-line stub last generated before the meson merge (no job-control endpoints).

Expected: Swagger generates from the annotations and the published spec covers the API. Impact: API documentation missing/stale. Found by: follow-up of the 2026-10-10 P0 fixes (bug-1936..1957)

Environment

  • OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
  • libc: glibc 2.42-47 (interpreter /nix/store/wb6rhpznjfczwlwx23zmdrrw74bayxw4-glibc-2.42-47/lib/ld-linux-x86-64.so.2)
  • Toolchain: gcc (GCC) 15.2.0, meson 1.9.1
  • Build: asan (xce.build)
  • Code: scheduler-framework @ 19be145d-dirty
  • Deployment: any (found by source reading; confirmed by the RED test of the fix)

Reproduction

  1. cd src/frontend/apiserver && swag init -g cmd/main.go -o /tmp/x: fails as above.
  • Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
  • Evidence: the code sites quoted in Description; no logs kept.

Root cause

Swag annotations in controllers/hosts.go and controllers/jobs.go named non-existent types (models.Error, ErrorResponse, JobsResponse, JobSignalRequest, JobControlResponseSummary), had malformed @Param/@Failure lines and wrong /api/v1 paths, and no general API info existed. Pre-existing.

Fix

Errors use JsonErrStruct (what ReturnError writes), success JsonStruct; bodies use models.JobSubmitRequest, JobControlJobIDRequest, JobControlRequest; paths match the routes; @BasePath /xce/v1 and general info in cmd/main.go; docs/docs.go, swagger.json, swagger.yaml regenerated with swag init -g cmd/main.go -o docs. Only hosts and jobs handlers are annotated so far.

Verification

  • Test: RED: swag init -g cmd/main.go failed with ParseComment error in file .../controllers/hosts.go ... models.Error: cannot find type definition; GREEN: swag runs cleanly and the spec lists /hosts, /jobs, /jobs/create, /jobs/{jobids}, /jobs/{jobids}/control, /jobs/control; cmd (imports docs) tests pass.
  • Suites: xce-build.sh all asan xce.build --incremental on the merged branch, 2026-10-10: C suites Ok 157 / Fail 0; frontend Go tests ok (the build now also runs apiserver cmd, middleware, models and router)
  • Live: n/a: unit/fixture-level verification; no live deployment was run
