# bug-1935: xcecli jobs list -P <project> fails: apiserver rejects project_name filter (unsupported filter)

## Description
**Observed:** `xcecli jobs list -P <project>` (`-P/--project`,
`src/frontend/xcecli/cmd/jobs/list.go:356`) sends the filter
`{project_name:eq:<project>}` (`xcecli/filters/job_filter.go:108-109`), but
`project_name` is commented out of the apiserver's `JOB_SUPPORT_FILTERS`
(`src/frontend/apiserver/models/jobs.go:178`), so `validateJobQueryFilters()`
(`controllers/jobs.go:470-483`) rejects the request:
```
unsupported filter: project_name
```
(HTTP 400, INVALID_PARAMS). The same holds for `license_project`
(`models/jobs.go:179`, `job_filter.go:112-113`). Found by source reading; not
yet run against a live apiserver.

**Expected:** `xcecli jobs list -P eng` lists the caller's visible jobs whose
project is `eng`.
**Impact:** wrong result: the documented `-P` (and license-project) filter of
`xcecli jobs list` always fails with an error; users cannot list jobs by
project. No data is affected.
**Found by:** review, during `/kiro-spec-requirements project-config`
(2026-10-10); `project-config` Requirement 7.5 needs this filter.
UPDATE (2026-10-10): confirmed by `TestJobHandler_ProjectFilters`
(`src/frontend/apiserver/controllers/job_scope_test.go`) before the fix:
`status = 400 ... unsupported filter: project_name`.

## 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), from src/xce.build/frontend/apiserver/xce_apiserver
- Toolchain: go1.25.5 linux/amd64 (nix dev shell); gcc (GCC) 15.2.0, meson 1.9.1
- Build: asan (xce.build) binary exists at this commit; the bug was found by reading the source, not by running it
- Code: scheduler-framework @ 54c8b29e
- Deployment: any apiserver deployment (single or HA); not reproduced on a running cluster yet

## Reproduction
1. Start an apiserver (any deployment) and submit a job with
   `xcecli jobs submit -P eng sleep 1`.
2. `xcecli jobs list -P eng`
3. Expected: the job is listed; per the source, the apiserver replies HTTP 400
   `unsupported filter: project_name`.
- Frequency: deterministic by code reading; not yet executed.
- Evidence: the code lines quoted in Description; no logs.

## Root cause
`JOB_SUPPORT_FILTERS` (`src/frontend/apiserver/models/jobs.go`) had
`project_name` and `license_project` commented out, and
`validateJobQueryFilters()` (`controllers/jobs.go`) rejects every field not on
that list, while `xcecli` (`filters/job_filter.go:108-113`) sends exactly
those fields for `-P` and the license-project option. The job store already
carries both fields (`JobInfo.ProjectName`, `LicenseProject`). Since:
pre-existing, origin unknown.
## Fix
`models/jobs.go`: `project_name` and `license_project` are now in
`JOB_SUPPORT_FILTERS`. No other change was needed: the store query filters
by the JSON field name. `ARRAY_JOB_SUPPORT_FILTERS` (array statistics) is
unchanged.
## Verification
- Test: `TestJobHandler_ProjectFilters`
  (`src/frontend/apiserver/controllers/job_scope_test.go`): RED before (400
  unsupported filter), GREEN after (`{project_name:eq:eng}` and
  `{license_project:eq:lic2}` select only the matching job).
- Suites: same run as bug-1934: apiserver and xcecli Go tests ok, meson
  `apiserver` suite 1/1 OK, asan, 2026-10-10.
- Live: n/a: the change is a filter whitelist entry exercised through the
  real handler and store in the test.
