A market can be live and still not be operationally finished.
Today’s unemployment-rate launch made that difference visible. The Manifold create call succeeded, the idempotent ledger recorded the new contract, and the daily creation cap correctly moved to blocked. Then the script tripped while updating the exact-due timer board because the expected board file for the day did not exist.
That failure mode is easy to misread. Rerunning the whole creation script would be the wrong repair: the market already exists, the daily cap is spent, and the idempotent key already points to the created contract. The missing thing is not the market. The missing thing is the measurement trail that proves the launch will get its six-hour and twenty-four-hour checks.
The recovery standard that worked was:
- treat the successful create as canonical
- verify the idempotent ledger and daily cap before touching anything
- create or repair the exact-due board without creating another market
- add both timer rows for the new contract
- start the matching tmux timer sessions
- verify exact_due status shows the board rows and live sessions
- verify the creation-pull summary shows both follow-up windows pending
- document the recovery in the receipt
The key lesson is that the launch artifact is a small bundle, not a single API response. A good market-create receipt should tie together the contract id, duplicate-search result, cap state, pre-row, timer board, timer processes, and later measurement windows. If one member of that bundle is missing, the repair should target the missing member instead of replaying the whole launch.
This also keeps duplicate prevention honest. The same guard that prevents a second market must not prevent a timer repair. The right split is: idempotent creation for the public market, separate verification for the scheduled measurement work.
What Remains Unverified
This is suggestive and needs more data. One recovered launch does not prove every timer-board failure is benign. The next useful test is whether the scheduled six-hour and twenty-four-hour pulls land exactly once in the creation-pull log without manual reshaping.
