Instance part of aeonfun/aeon#1232 (Langfuse review 2026-10-16). This instance's narrowed workflow differs from canon, so it gets its own PR, like #1230's instance PRs.

1. No real notifications from test branches. "Send pending notifications" now needs github.ref_name == github.event.repository.default_branch, like the health-issue step. Thursday's workflow_dispatch runs of holdings on verify/langfuse-models / verify/langfuse-slicing each delivered a real Telegram card ("Delivered 1/1"). Repo variable NOTIFY_ON_BRANCH=1 opts a test branch back in; skipped payloads sit in $RUNNER_TEMP and are dropped.
2. trigger input, ahead of the sync. Adds the optional trigger input and the AEON_DISPATCH_TRIGGER env, same text as canon. Inert for now (the current langfuse-otel.sh does not read it). It lands first so that when aeon-update brings the Scheduler passing -f trigger=cron, this workflow already accepts it (the canon Scheduler also retries without it).
3. holdings picks its own windows (instance-only skill). holdings.py reads the HOLDINGS_STATE: lines in memory/logs + memory/logs/archive and prints growth.<symbol>.{last,7d,30d} (null when no snapshot is inside the +/-2 / +/-4 day range); step 2 only renders it, never recomputes. Two runs 80 min apart on 10-15 sent "7d +246.04M (vs 10-05)" and "7d building" from the same snapshots; 10-05 was 10 days back, outside the skill's own rule. --no-history for a one-off var wallet. The notify card gets a one-line sources footer (the scorer gave the bare stat line a 2), and the % Supply miss renders n/a.

Arrives with the next aeon-update (not in this PR): the usage_details 1h/5m cache-write pricing in otel-span.sh, the fleet-scorecard price, the lean scorer (needs the new run-harness --no-tools), the trigger mapping, the Scheduler / chain-runner input, and the memory-flush byte budget.

Checked: actionlint, validate-config.js, test_workflow_harness_choices.sh and test_langfuse_otel.sh (same result as main), and holdings.py run live against memory/holdings.json (today: last vs 10-12, 7d null, 30d vs 09-14).
