   - `npm test -- --runInBand` ❌ `vitest: command not found`

+- Reran required branch hygiene before attempting edits: `git fetch origin && git merge --no-edit origin/main` (clean on `origin/main` baseline).
+- Revalidated the repo-defined test command on Node `20.11.1`:
+  - `rushx test` ❌ fails immediately because tests import removed legacy paths (`../src`, `../src/router`, `../src/logging`, `../src/zod-procedure`).
+- Rationale for no source edits this slot: source-change gate requires passing validation in-run, but test harness currently fails before executing any assertions due broken import paths.
+- Next actionable unblock: migrate test imports/fixtures off `src/*` aliases to current flat layout (or add compatibility re-export shims) in one focused patch, then rerun `rushx test`.

 - Next actionable unblock: migrate test imports/fixtures off `src/*` aliases to current flat layout (or add compatibility re-export shims) in one focused patch, then rerun `rushx test`.

+## 2026-02-20 websocket integration follow-up (06:22 PT)
+- Updated CLI runtime output handling in `index.ts` to log non-undefined procedure results (`logger.info`) so README examples now return visible output again (for example `rushx cli math.add 1 1` returns `2`).
+- Verified direct CLI↔cerebro-link websocket flow with a live local server (`PORT=8081 rushx dev` in `cerebro/link` + `CEREBRO_SERVICE_URI=ws://127.0.0.1:8081 rushx cli cerebro.info` in `cli`) and confirmed expected payload output (`{"name":"Cerebro Link"}`).
+- Kept README command docs aligned with this checkout (`rushx cli ...` and `./bin/arken ...`; module paths under `modules/*`) so documented commands are executable as written.

 ## Local test-gate note (rotation automation)
-In this checkout, test execution is currently blocked until dependencies/workspace links are restored:
-- `rushx test` may fail if Rush cannot resolve all workspace packages.
-- `npm test` requires local `vitest` to be installed and available.
+Use Node 20 and Rush scripts in this workspace:
+- `source ~/.nvm/nvm.sh && nvm use 20`

 - Updated CLI runtime output handling in `index.ts` to log non-undefined procedure results (`logger.info`) so README examples now return visible output again (for example `rushx cli math.add 1 1` returns `2`).
 - Verified direct CLI↔cerebro-link websocket flow with a live local server (`PORT=8081 rushx dev` in `cerebro/link` + `CEREBRO_SERVICE_URI=ws://127.0.0.1:8081 rushx cli cerebro.info` in `cli`) and confirmed expected payload output (`{"name":"Cerebro Link"}`).
 - Kept README command docs aligned with this checkout (`rushx cli ...` and `./bin/arken ...`; module paths under `modules/*`) so documented commands are executable as written.

+- Rationale: while validating the now-runnable `rushx test` gate, the CLI error path still emitted a stray debug line (`throwing error`) when `--verboseErrors` was used. That extra stdout noise can pollute automation and makes verbose mode less reliable.
+- Change scope:
+  - Removed the debug `console.log('throwing error')` side-effect from the verbose `die(...)` path in `index.ts`.
+  - Added `test/verbose-errors.test.ts` to lock expected behavior: verbose errors should throw, avoid forced process exit, and avoid debug-noise stdout.
+- This keeps behavior practical (no extra abstraction), aligns with reliability-first maintenance, and preserves explicit throw semantics in verbose mode.

   - Added `isArrayFlagBoundary(...)` in `index.ts` so array-value capture boundaries are tied to declared short aliases and long flags, reducing accidental early termination from unrelated short tokens.
   - Added `test/parsing.test.ts` coverage (`array flag accepts short-alias equals values`) using alias mapping to lock repeated `-v=...` handling with trailing flags.
 - Practical impact: list-style flag parsing behavior is now test-locked for short-alias equals input style without adding router-layer abstractions.
+
+## 2026-02-20 slot-11 follow-up (18:4x PT)
+- Rationale: array-list flags already supported `--flag value` and `--flag=value`, but short alias values attached without `=` (for example `-valpha`) were not collected into array inputs, causing silent value loss for a common CLI style.
+- Change scope:
+  - Updated `index.ts` array-flag collector to accept short-alias attached values (`-valpha`) in addition to `-v alpha` and `-v=alpha`.
+  - Added regression coverage in `test/parsing.test.ts` (`array flag accepts short-alias attached values`) to lock behavior with trailing flags.
+  - Updated `README.md` list-flag examples to document attached short-alias form.
+- Practical impact: list-style flag parsing is now consistent across common shorthand variants without introducing extra router/procedure abstraction.
+
+## 2026-02-20 slot-11 follow-up correction (18:4x PT)
+- Correction: attached short-alias array syntax (`-valpha`) is parsed by the argument parser as bundled short options and is not a supported input form in this CLI.
+- Final slot change:
+  - Added explicit regression coverage in `test/parsing.test.ts` for repeated short-alias spaced list values (`-v alpha -v beta`) with trailing flags.
+  - Updated `README.md` list-flag examples to document supported short-alias list syntax accurately.
+- Practical impact: parser expectations are now test-locked for supported short-alias multi-value usage, reducing ambiguity for CLI callers and docs drift.

In maintenance/runtime environments this creates avoidable websocket connection attempts and can keep Node processes alive longer than needed.
+- Change scope:
+  - Added argv-aware route targeting (`resolveRequestedRoute` + `shouldInstantiateRoute`) so a namespaced command only instantiates the requested remote route plus local fallback routers.
+  - Applied the same route filter to backend socket client creation to avoid unnecessary remote socket setup for unrelated namespaces.

+- Change scope:
+  - Updated shorthand regex in `index.ts` (both normal and interactive paths) to accept hyphenated agent/method identifiers.
+  - Corrected interactive shorthand match destructuring to use capture groups consistently (`[, agent, method, paramsString]`).
+  - Added regression coverage in `test/parsing.test.ts` (`shorthand parser accepts hyphenated agent and method names`).

   - Corrected interactive shorthand match destructuring to use capture groups consistently (`[, agent, method, paramsString]`).
   - Added regression coverage in `test/parsing.test.ts` (`shorthand parser accepts hyphenated agent and method names`).
 - Practical impact: shorthand calls now support common hyphenated identifiers reliably in both one-shot and interactive CLI modes.
+
+## 2026-02-21 cron run follow-up (13:2x PT)
+- Rationale: README examples include both `cerebro.exec --agent ... --method ...` and shorthand `Hisoka.run()` forms, but the existing websocket README interop test only locked `cerebro.info`/`cerebro.ask`; adding `cerebro.exec` coverage exposed a real transport gap (`TRPC handler does not exist for method: exec`) and closed the doc-to-runtime gap.
+- Change scope:
+  - Extended `test/cerebro-readme.test.ts` to execute and assert both README-style exec variants over the live tRPC websocket bridge:
+    - `rushx cli cerebro.exec --agent Hisoka --method run`
+    - `./bin/arken cerebro.exec Hisoka.run()`
+  - Assertions verify payload fields (`agent`, `method`) from the link service response.
+- Practical impact: README command reliability checks now include exec request/response flow in addition to info/ask, strengthening end-to-end CLI↔cerebro-link confidence and catching transport regressions quickly.
+
+## 2026-02-21 cron run follow-up (13:2x PT, parser correction)
+- Rationale: shorthand no-arg form `Hisoka.run()` was being expanded with an empty `--params` token, producing `params: [""]` instead of an empty list and diverging from expected README semantics.
+- Change scope:
+  - Updated shorthand argv reconstruction in `index.ts` to include `--params` only when parsed params are present.
+  - Added regression coverage in `test/parsing.test.ts` (`shorthand parser with empty parens omits params flag`).
+- Practical impact: no-arg shorthand exec now serializes cleanly as `params: []` in live CLI↔cerebro-link websocket calls.

+# from arken/cerebro/link
+source ~/.nvm/nvm.sh
+nvm use 20
+PORT=8090 rushx dev
 ```
 
+Then run CLI commands against that websocket URI:
+
+```bash
+CEREBRO_SERVICE_URI=ws://127.0.0.1:8090 rushx cli cerebro.info
+CEREBRO_SERVICE_URI=ws://127.0.0.1:8090 ./bin/arken cerebro.info
+```
+
+If you run `rushx dev` without `PORT`, cerebro-link may auto-select another free port. Use the printed `ws://localhost:<port>` value for `CEREBRO_SERVICE_URI`.
