Development record
2026-10-16 — A first read of a status branch that runs past the walk limit is always shown as doubtful, continuity not verified, whatever times its commits carry, refining dcn-2610161320457650 and dcn-2610161100416718 (spc-2610150728396006 step 3 fix round 3, on review). Within the bounded walk no signal settles whether a line older than what the read took in can still stand, so the read cannot say that nothing beneath it is live.

- dcn-26101611004167182026-10-16 — A status branch this checkout has never read that holds more than one read covers is shown as doubtful, continuity not verified: more was added than one read covers, the same as a branch read from a mark (spc-2610150728396006 step 3 fix round, build note 24 extended; decided by the facilitator on delegation). A first read that stopped at the walk limit could otherwise bury a live announcement under a thousand ended ones with no sign.
- dcn-26101613204576502026-10-16 — A first read of a status branch that runs past the walk limit is shown as doubtful only while something beneath what it read could still stand: when the oldest commit it read does not read as an announcement, or was sent, by the time it carries, less than a day and an hour before the read (the longest life plus C9's one-hour slack), refining dcn-2610161100416718 (spc-2610150728396006 step 3 fix round 2, decided by the facilitator on delegation). Status branches only grow, so every new checkout's first read of a long-lived one passed the limit and showed a doubt for history that had all ended. The bound is the oldest commit's send time rather than its own expiry, since a commit beneath it, sent earlier with a longer life, can outlast it.
- dcn-26101619073156562026-10-16 — A status branch holding more new commits than one intake takes in is no longer shown as doubtful: it is left unmarked, the branches after it are not walked once nothing is left to take in, the block counts each branch left as not read yet, and the next intake starts at the branch after where this one stopped; continuity not verified stays only for a walk that itself ran out, refining dcn-2610161737571276 (spc-2610150728396006 step 3 fix round 4, on review). A read mark at the tip passed the commits the cap left over for good, and a lasting doubt told the person nothing they could act on.
