What Changed

• Adds a csharp.outDir setting to .metaobjects/config.json, read by NeutralConfig and surfaced on ResolvedMetadata.OutDir. Relative paths resolve against the directory holding .metaobjects/. Unknown keys, a non-object block, or an empty or non-string outDir are refused with ERR_BAD_ATTR_VALUE.
• dotnet meta gen and dotnet meta verify --codegen fall back to csharp.outDir when --out is omitted, so a bare dotnet meta verify runs the codegen gate against the directory gen writes to. An explicit --out still wins. With neither set, the skip note now names the setting. A malformed config is reported as the real error, not as a usage line.
• The TypeScript ConfigSchema declares the csharp block so the shared config validates without unknown-key warnings. Docs (docs/features/cli.md, docs/ports/csharp.md), the CHANGELOG entry, and the C# agent-context references are updated to match.

Validation

Risk Assessment

✅ Low: Change is small and additive: csharp.outDir is read, validated and resolved consistently for gen and verify, an explicit --out still wins, and the prior round's malformed-config fix now reports the real error. The other ports ignore the new config block, and the TypeScript reader declares it. No concrete failing path found.

Testing

Driven live against the built C# CLI in a disposable project. Bare verify runs the codegen gate from csharp.outDir: clean passes, drift and missing files fail naming the file. --out overrides config, no-config keeps the skip note, and malformed config shows the real error on bare verify, gen and verify --codegen, so the review-1 fix holds. Full C# solution tests passed with 0 failures, plus the TS baseline. Overall pass; one cosmetic info on the drift hint wording.

Scenario	Result	Live	Evidence
Plain bare verify with csharp.outDir configured: gate runs and passes on in-sync output	✅ pass	live	~/.no-mistakes/evidence/01M60KBFDTQZ64FPKQ6C2D3V8J/csharp-bare-verify-outdir.txt (S1: verify metaobjects gives 'verify --codegen: OK', exit 0)
Bare verify catches a hand-edited generated file and exits 1 naming the file	✅ pass	live	csharp-bare-verify-outdir.txt (S2: '~ Author.g.cs', exit=1)
Bare verify catches a deleted generated file and exits 1	✅ pass	live	csharp-bare-verify-outdir.txt (S3: '+ Author.g.cs not committed', exit=1)
Explicit --out overrides csharp.outDir for verify	✅ pass	live	csharp-bare-verify-outdir.txt (S4: verify --out empty dir reports drift; S5: --out generated checks that dir)
gen with no --out writes to csharp.outDir	✅ pass	live	csharp-bare-verify-outdir.txt (initial gen wrote generated/Author.g.cs; S9 reports unchanged)
No csharp.outDir: bare verify keeps the skip note and exits 0	✅ pass	live	csharp-bare-verify-outdir.txt (S6: codegen gate skipped note, exit=0)
No csharp.outDir and no --out: gen prints usage naming the setting, exit 2	✅ pass	live	csharp-bare-verify-outdir.txt (S6b, exit=2)
Adversarial: non-string csharp.outDir shows the real config error, not usage, across bare verify, gen and verify --codegen	✅ pass	live	csharp-bare-verify-outdir.txt (S7, S7b, S7c: error: ERR_BAD_ATTR_VALUE ... must be a non-empty string, exit=2)
Adversarial: misspelled key csharp.outdir and non-object csharp block are refused with the real error	✅ pass	live	csharp-bare-verify-outdir.txt (S8, S8b, exit=2)
Config restored after the error cases: gen and bare verify work again	✅ pass	live	csharp-bare-verify-outdir.txt (S9, S9b, exit=0)

• ⚠️ server/csharp/MetaObjects.Codegen/CodegenCli.cs:667 - ConfiguredOutDir swallows MetaModelException/MetadataLocationException and returns null. In the owned gen and verify --codegen runners, a malformed config (e.g. "csharp": { "outdir": "x" }, a non-string outDir, or a bad sources) with no --out hits the usage branch. The runner prints usage: ... --out <dir> and (or set "csharp": { "outDir": ... }), then exits 2. The real error (ERR_BAD_ATTR_VALUE naming the bad key) is never shown. The user is told to set the very key they already set wrongly. Same class at CodegenCli.cs:854 (verify --codegen runner). Program.cs bare verify is unaffected because ResolveMetadataDirOrExit reports first. Fix: when resolution throws, fall through to ResolveOrReport so the real error prints, instead of reporting usage.
• ℹ️ server/csharp/MetaObjects.Codegen/CodegenCli.cs:597 - The XML doc summary for ResolveOrReport had been displaced above the new ConfiguredOutDir method, leaving two stacked summaries on one member. Moved the ResolveOrReport summary back above ResolveOrReport. Comment-only change.
