`iris_doc mode=list` fails with HTTP 400 for `category` MAC/INT/INC and for the default `ALL`: Atelier `docnames/:cat` only accepts `*`, `CLS`, `RTN`, `CSP`, `OTH`

Environment

• iris-agentic-dev v1.3.0 (same code in v1.4.2 and on master at 5f38c46)
• Windows 11, IRIS for Health 2026.1 (Build 235U), Atelier REST through the web server on port 80
• MCP mode, connection from .iris-agentic-dev.toml

Symptom

iris_doc with mode="list" works only when category="CLS" is passed explicitly:

Because ALL is the default, any list call without an explicit category fails, and MAC/INT/INC can never work.

Root cause

fetch_docnames_for_cat builds /docnames/{cat} with cat in CLS, MAC, INT, INC
(doc.rs#L1704-L1726, and the category mapping at
#L1744-L1766).

In the Atelier API, MAC, INT and INC are types inside the RTN category, not categories. The route
is GET /api/atelier/v1/:namespace/docnames/:cat/:type, and %Api.Atelier.v1:GetDocNames (identical in v2 and
v8 on 2026.1) rejects any other :cat with 400:

Set pCat=$zcvt(pCat,"U")
If ",*,CLS,RTN,CSP,OTH,"'[(","_pCat_",") {
    Set %response.Status=..#HTTP400BADREQUEST

In addition, the ALL loop returns on the first failing category
(#L1780-L1791),
so the CLS results already fetched are discarded.

Reproduction without the tool

Plain GET with Basic auth against the same instance and namespace:

Suggested fix

1. Map MAC → /docnames/RTN/MAC, INT → /docnames/RTN/INT, INC → /docnames/RTN/INC. For ALL, one call to
   /docnames/CLS plus one to /docnames/RTN/MAC,INT,INC is enough.
2. Do not throw away the successful categories when one fails in ALL: return what was fetched and report the
   failing category, or fail with a message that says which request was rejected.
3. A regression test for list without category (and with MAC/INT/INC) against a live IRIS would catch it.

Workaround

Always pass "category":"CLS" for classes. For routines and include files there is currently no working list
mode.

Start in crates/iris-agentic-dev-core/src/tools/doc.rs, especially fetch_docnames_for_cat, the category mapping, and the ALL loop. Compare those requests with the documented Atelier docnames routes, then run a live IRIS regression test for default ALL and MAC/INT/INC categories. Done means valid routine-type requests succeed and ALL preserves or clearly reports category results when a request fails.
