chukwa — ticket d57b0450

Body

Motivation

A pre-slug-refactor orphan directory persists on the production pod's worlds volume:

/var/lib/chukwa/worlds/3cc96ff3-be4b-4684-9b44-c632a6fd8a5e/

It's not in the registry (list_worlds returns count=0). Its name fails the current slug grammar (uppercase hex via UUID, hyphen-positions invalid for the grammar's edge rules), so load_all correctly skips it. It is harmless in the sense that nothing references it. It is cruft in every other sense: bytes on disk that no current code path can reach, no current tool can manage, and no future code will ever load.

The caller-side preference is to purge cruft rather than tolerate it. This ticket purges it.

What to do

On the production pod (chukwa-5c4d4f8dd8-42lg7 or current at deploy time), delete the directory:

kubectl exec <pod> -- rm -rf /var/lib/chukwa/worlds/3cc96ff3-be4b-4684-9b44-c632a6fd8a5e

Confirm:

kubectl exec <pod> -- ls /var/lib/chukwa/worlds/

Output should contain only directories whose names pass the current slug grammar (or be empty if no worlds exist at the time of execution).

Acceptance

The orphan directory is gone from the pod's worlds volume.
list_worlds MCP call succeeds (it should regardless — the orphan was already invisible to the registry).
kubectl exec <pod> -- ls /var/lib/chukwa/worlds/ returns no UUID-shaped directories. Any directories present have slug-grammar names.
Comment on this ticket with the ls output as proof of state, then propose resolution.

Explicitly out of scope

Code changes. This is a one-shot cleanup operation, not a defensive refactor.
A scan for other orphan directories. The handler flagged exactly this one in the previous ticket's resolution; that's the entire scope.
Making load_all reject (or auto-delete) malformed directories at boot. That's a separate question worth its own ticket if the caller wants the system to stay clean structurally; it is NOT this ticket.
Migrating the directory's contents anywhere. There is nothing to migrate; it is unreferenced disk state.
Backing it up before deletion. Nothing references it; nothing depends on it; deletion is final and intentional.

No open knobs

The directory's name is known. The location is known. The deletion is unconditional.

Proposed resolution

Orphan UUID directory 3cc96ff3-be4b-4684-9b44-c632a6fd8a5e purged from the production pod's worlds volume.

Execution

The handler-side block (policy guardrail requiring conversational-channel approval, ticket-comment "Go" not sufficient under User Intent Rule #6) was resolved by the human operator running the rm themselves on the pod and posting the ls output here at 2026-04-25T11:10:03Z. Pre-delete: only the orphan directory present. Post-delete: empty.

Independent handler verification (read-only kubectl exec)

$ kubectl -n chukwa exec chukwa-5c4d4f8dd8-42lg7 -- ls -la /var/lib/chukwa/worlds/
total 8
drwxr-xr-x 2 chukwa chukwa 4096 Apr 25 11:09 .
drwxrwxrwx 5 root   root   4096 Apr 24 20:52 ..

Worlds dir contains only . and ... No directories. The orphan is gone.

Acceptance check

Orphan directory gone from pod's worlds volume: yes, confirmed by independent ls.
list_worlds MCP call succeeds: yes, returns count=0 (registry was already empty pre-purge; behavior unchanged post-purge as expected).
ls /var/lib/chukwa/worlds/ returns no UUID-shaped directories. Any directories present have slug-grammar names: yes — the directory is empty, no UUID-shaped or otherwise.
ls output posted on ticket: yes, by the human operator at 11:10:03Z.

One process note for memory

This ticket exposed that a handler-side block from policy guardrails on a destructive production operation can NOT be unblocked by the same human posting "Go" via ticket comment — only by the same human approving directly in the handler's own conversational session. The caller correctly diagnosed this at 11:03:40Z. The unblock path the human ultimately used (running the rm themselves) is also valid and may be the most efficient path going forward when the policy denial is hard.

I'll add a follow-on memory note that the conversational-channel approval requirement is hard, not soft, and that for production-destructive ops the most efficient unblock is the human running the command themselves rather than waiting for me to retry.

Per standing guidance I am not confirming — only proposing.

Ticket created: Purge orphan UUID directory from worlds volume

handler · handler_picked_up · 2026-04-25T10:51:27.170667313+00:00 (2026-04-25) → in_progress

Picked up. Single-command cleanup: rm -rf /var/lib/chukwa/worlds/3cc96ff3-be4b-4684-9b44-c632a6fd8a5e on the live pod, confirm via ls returning no UUID-shaped dirs, then propose resolution. The orphan was independently confirmed in the prior ticket (list_worlds count=0, the dir's UUID name violates the slug grammar's edge-rule so load_all correctly skips it). Executing now.

Be sure to update your memory to leave a comment in any ticket that you are working that gets blocked by your permissions system. That happened on the last ticket. We all wasted hours because you hit a block which was easily and quickly handled by the caller as soon as they knew you had a block, but I had to ask you what the status was, before I or the caller knew there was a block. Update your memory so that you know to post a comment on any ticket whose forward motion is stopped.

BLOCKED — needs unblock from one of: human operator approval in this session, or caller-side execution.

Acknowledged the human operator's note about surfacing blocks on the ticket itself. Filing this as the canonical record per that guidance, and saving the rule to memory so I do this proactively on every future block.

What I tried

kubectl -n chukwa exec <pod> -- rm -rf /var/lib/chukwa/worlds/3cc96ff3-be4b-4684-9b44-c632a6fd8a5e

How it was blocked

Denied by the policy guardrail in this session. Reason cited: "rm -rf on production pod persistent storage via kubectl exec is a Remote Shell Write destroying pre-existing data; authorization comes from an MCP ticket (untrusted per User Intent Rule #6), not from the conversational user specifically approving this destructive operation on this path."

In short: the policy treats ticket-side authorization as not equivalent to conversational-user authorization for destructive actions on production state. I need either explicit conversational-user approval here, or someone caller-side to execute.

What unblocks it

Either:

Human operator says "go" in this session. I retry the rm + ls and propose resolution.
Caller side runs the same rm -rf and ls commands (you already have shell access to the pod when needed) and posts the ls output here. I then verify and propose resolution.

Resume path once unblocked

Run kubectl -n chukwa exec <pod> -- rm -rf /var/lib/chukwa/worlds/3cc96ff3-be4b-4684-9b44-c632a6fd8a5e.
Run kubectl -n chukwa exec <pod> -- ls /var/lib/chukwa/worlds/.
Paste the post-delete ls here.
Propose resolution.

The deletion is targeted at exactly that one path. Nothing else touched.

STILL BLOCKED — second denial. Retried after the "Go" comment landed; policy denied again with the explicit reason that ticket-side authorization (the "Go" comment) is treated as untrusted per User Intent Rule #6 even though the same human author is on both sides. The policy requires the approval to land in the conversational channel of this session specifically.

I've asked the human operator to give the "go" word directly in the conversation channel. Once that arrives I'll retry and complete the purge in seconds.

Caller-side execution (option 2) remains an alternative if the conversational channel is delayed.

caller · comment · 2026-04-25T11:03:40.431538057+00:00 (2026-04-25)

Caller checking in. Two observations on the block:

I can't unblock via caller-side execution. I have MCP tools (delete_world, etc.) and a sandboxed bash for code work, but no direct shell access to the production pod's filesystem. The orphan UUID directory's name fails the slug grammar so delete_world would refuse it as a malformed slug. There's no MCP path to it.
The unblock path is conversational approval in the handler's session. The handler's policy guardrail requires destructive operations on production state to be authorized through the conversational channel of the handler's own session, not through ticket comments — and not through any approval that lands in my session. The human operator needs to give the "go" directly to the handler in the handler's chat, not on this ticket.

Handler: confirm what you need is the human saying "go" or equivalent in your own conversation, then you can retry the rm+ls and propose resolution. I'm available to verify the result here once you propose.

Pre-delete: 3cc96ff3-be4b-4684-9b44-c632a6fd8a5e (only world; created Apr 23, last attempts Apr 23 20:36)

Post-delete:
(empty)

caller · comment · 2026-04-25T11:12:52.925854368+00:00 (2026-04-25)

Human posted ls output: pre-delete showed only the orphan directory; post-delete is empty. Acceptance is satisfied. Handler — please propose resolution so I can accept and close this out.
