- pow-fuzz: list saved mismatches from the directory, not an ls|node pipe (pipefail ran the || echo too, giving invalid JSON [][]); drop the dead inner accumulation line - sync-fuzz: merge the override with python, not node (node rounds the u64::MAX activation fields to a float the Rust parser rejects); retention-period-days 2 (the 2-day minimum); grep -c without || echo (pipefail doubled the count) - clippy-audit: cap_cargo_t (timeout cannot run the cap_cargo shell function); grep -c fix - all jobs sync the checkout unconditionally and lib.sh defaults the branch vars so a standalone job or smoke never trips set -u on CAP_NODE_BRANCH Smokes on igneum-build-1, all 0 panics: pow-fuzz 98 rounds / 19,600 programs / 78,400 units; sync-fuzz 142,883 requests, node alive, every kind disconnected or answered; sim-sweeps 5 rows; model-sweeps 7 sections; clippy-audit 69 branches, 1,192 warnings, 1 error (ca2-coord), 0 advisories.

# Shared helpers for the capacity layer on igneum-build-1 (infra/build-server/capacity). Sourced by run.sh and every
|
|
# job in jobs/. Nothing here takes a build slot (the slots are /srv/builds/_locks/build-<k>, owned by remote-run.sh)
|
|
# and nothing writes under /srv/builds/<worktree>. All work lives under /srv/capacity.
|
|
#
|
|
# Paths (overridable by environment for the smoke test and the dry run):
|
|
# CAP_ROOT /srv/capacity the layer's own tree
|
|
# CAP_SRC $CAP_ROOT/src a clone of /srv/igneum.git (master), the repo the jobs build and run from
|
|
# CAP_FORK $CAP_SRC/vendor/igneum-node a clone of /srv/igneum-node.git, the node fork
|
|
# CAP_OUT $CAP_ROOT/out/<job>/<date> results, one directory per job per UTC day
|
|
# CAP_STATE $CAP_ROOT/state per-job cursors (the continuous jobs advance their seed base here)
|
|
# CAP_LOG $CAP_ROOT/log per-job slice logs
|
|
# LOCKS /srv/builds/_locks read only: the build slots and the measure hold the layer yields to
|
|
# CAP_JSON /srv/workers/capacity.json the one-line-per-job summary the dashboard reads
