Three sentences in this handoff had become false. Each one in the way the doc itself keeps warning about, which is why they are worth a PR rather than a silent fix in the next revision.

1. The store bullet is closed, so the instruction to close it must stop reading as open

devrc/cairn's 2026-08-29: OPEN: no entry in this store carries a task, PR or session ref is now RESOLVED caec932e: via cairn put (revision da318a4c6a96f9d8).

Closure is named, not asserted: the implementing site is ATTRIBUTION = " [cairn: {actor}/{session}]" in scripts/subsystem-store-api/server.py, appended server-side from the authenticating token so a body cannot forge someone else's attribution.

The control is the badge, not the write. The index row moved 17 nuance / πŸ”΄ 2 OPEN β†’ 18 nuance / πŸ”΄ 1 OPEN β€” both dimensions I touched. Bytes landing is the weaker claim.

⚠ The surviving πŸ”΄ 1 OPEN is a different bullet (2026-09-01, the scope merge rule). I gathered no evidence about it and left it: closing an unverified marker is worse than leaving it open.

2. The stale-doc gotcha claimed to be a discovery, and is not one

This is a correction of my own writing in the previous PR, and it inverts what the block claimed to be.

/resume step 1 already carries the rule β€” "The working-tree copy is a GUESS about what the handoff says β€” run step 2 FIRST and read the copy it names" β€” backed by two measurements older than this session: a datapacket clone serving a handoff 276 lines behind origin/trunk, and a clone serving a skill file 692 commits stale.

πŸ”΄ And the tooling that prevents it was never run. scripts/resume-state.sh resolves the doc, fetches, compares, and prints handoff-read: naming the authoritative copy. Step 2 orders it before the read for exactly this reason. This session hand-rolled git/gh instead β€” which step 2 explicitly forbids β€” walked into the trap the tool exists to prevent, and wrote it up as novel.

The block is corrected rather than deleted: the measurement in it is still true, the framing was wrong.

When the reconciler was finally run (22:11Z) it reported the tree copy still stale, 829 local vs 930 on origin/main, hours after the merge β€” plus a !! GAPS block: gh answered for 5 of 6 referenced PR(s). A digest with a gap block is not an all-clear, and a hand-rolled check cannot produce that distinction at all; it reports a gap as nothing.

3. Rank 3 is no longer unpushed

The doc states the other session's slice-2 work is a clean local commit, "unpushed, no PR yet". It is now open as devrc #1406 (feat/cairn-flake-pin). Found by the pre-create gh pr list sweep that step 6 asks for β€” and that the previous PR ran only after creating, which is the wrong order.

The rank-3 claim is untouched and still theirs (rc 10).

…at claimed novelty it did not have, and a superseded "unpushed"

Each of these was a sentence in this doc that had become false, in the exact way
the doc itself keeps warning about.

1. THE STORE BULLET IS CLOSED, so the instruction to close it must stop reading
   as open work. `devrc/cairn`'s `2026-08-29: OPEN:` is now `RESOLVED caec932:`
   via `cairn put` (revision `da318a4c6a96f9d8`), naming the implementing site
   rather than asserting closure: `ATTRIBUTION = " [cairn: {actor}/{session}]"`
   in `scripts/subsystem-store-api/server.py`, appended server-side from the
   authenticating token. The control that it did what it claimed is the index row
   moving `17 nuance / 2 OPEN` to `18 nuance / 1 OPEN` β€” both dimensions touched,
   not merely bytes landing. The surviving OPEN is a different bullet and was
   deliberately left unverified rather than closed on no evidence.

2. THE STALE-DOC GOTCHA CLAIMED TO BE A DISCOVERY AND IS NOT ONE. `/resume` step
   1 already carries the rule, backed by two older measurements (a 276-line-stale
   handoff, a 692-commit-stale skill file), and `scripts/resume-state.sh` exists
   to prevent it β€” step 2 orders it BEFORE the read for that reason. This session
   hand-rolled git/gh instead, which step 2 forbids, walked into the trap the tool
   was built to prevent, then wrote it up as new. Correction appended rather than
   the block deleted: the measurement is still true, the framing was wrong.
   When the reconciler was finally run it reported the tree copy stale at 829 vs
   930 lines AND a gap block (`gh answered for 5 of 6 referenced PR(s)`) β€” a
   distinction a hand-rolled check cannot produce, since it reports a gap as
   nothing at all.

3. RANK 3 IS NO LONGER UNPUSHED. The doc says the other session's work is a local
   commit with no PR; it is now open as devrc #1406, found by the pre-create
   `gh pr list` sweep that step 6 asks for and that the previous PR ran only
   afterwards. The claim is untouched and still theirs.
