From 11db1759c4e4c377de3dc7dc4b19e9660e11206b Mon Sep 17 00:00:00 2001 From: Michael Taylor Date: Sun, 27 Sep 2026 04:55:25 -0700 Subject: [PATCH 1/3] chore(rewards): UNVERIFIED checkpoint of the #3323/#3324 honesty work SALVAGED FROM A LANE KILLED MID-BUILD. At the time of this commit the code had NEVER COMPILED -- the lane died waiting on a cold build before any cargo run finished. It exists so a session cap could not take the work again. CORRECTION to this message's first draft, which claimed the #3323 fold was NOT applied here: it was. `git diff HEAD` reports the WORKING TREE, but a commit records the INDEX, and the dead lane had staged the fold and then reverted it in the tree to confirm its test reddened first. Reading the tree and describing the commit is how that claim went wrong. Read `git diff --cached`, or both columns of `git status --porcelain`. State as salvaged, corrected: - #3324: report_io_failed + refuse_io_failed helpers in rewards/funded.rs and an_io_failed_read_is_logged_with_its_path_and_error. - #3323: both the RED test in lib.rs AND the dispatch.rs fold it asserts.

Fold each report's own observed_at across the loop and keep the oldest -- a collection is only as fresh as its stalest member. Both NotConsulted arms and the empty FundsNothing case keep the handler's clock unchanged: no chain read happened for those, so it remains the honest answer.
