type: goal

text: there is constant disk space problems both on my laptop and on debian1/debian2 ci offload machines, i want to systematically fix this. find the root cause of it, and mitigate. i want you to come up with a plan, and then consult with both /dead-advisor (fable) and with /ask-codex gpt-5.6-sol/high about this, and all you three together come up with a fool-proof solution that will not have me deal with this ever again.


type: methodology

text: Root-cause first; preserve working caches and active data; reclaim only provably unreferenced artifacts; execute the entire converged plan, including the data-loss fix; verify deployment and armed runtime state.


type: intent

text: Make disk usage bounded by lifecycle ownership and admission control instead of repeatedly clearing useful caches or treating pressure symptoms.


type: direction

verbatim: you are doing the wrong thing. the caches are there to work. we are heavy work machine here. you clear the cache, in 1hr the caches are back and all you did is just got more hdd work and no benifit. You must take into account the situation. What did i ask in the 1st prompt?  consult with both /dead-advisor (fable) and with /ask-codex gpt-5.6-sol/high about this, and you did none of them.


verbatim: you are not looking for the root cause, which is what i asked. you are just dealing with symptoms


verbatim: i want to keep all session transcripts. do not prune or delete them . iam using them


verbatim: do the entire thing, i want all the plan executed and the data loss fix


verbatim: any changes to the harness must be committed and pushed otherwise they will be overwritten by a paralel session


verbatim: look i really dont care about ntfy and dont even use it. if it's a blocker just disable it and move on


type: anchor

what: converged implementation plan and shipped-state record


what: root-cause analysis and five-wave disk hygiene specification


what: project-wide operating instruction


note: Both requested consultations completed: dead-advisor/fable and Codex gpt-5.6-sol/high. Converged design: reference/ownership detection, not cache classification; walk-free measurement; lifecycle GC; admission control; sustained growth alarm; data-loss protection for precious ignored files.


note: Implementation and deployment reported complete on mega-plan-harness main, engine bundle 0.1.59 armed. Measured 326 worktrees, 66 reaped, 75 GiB free versus 53 GiB at diagnosis; second pass 0 reapable. Laptop notify disabled; debian1 ntfy disabled; CI alarms use syslog.


note: No remaining user-ordered deferred work or external blocker recorded. Current transcript turn is /fix-rot recovery; resume by validating shipped-state claims against live anchors/runtime if needed, then continue only on concrete failures.
