docs(devlog): record the Wave 5 WP5 triage outcome (#1849 split, #1049 assessed) - #1943
Merged
Conversation
#1849 was two defects wearing one issue number. #1877 stopped the service wrapper hammering a missing install and shipped in v2.24.0; nothing has been done about how the install went missing, which is npm install -g removing the existing package before the replacement is verified. That half is now #1942 and the umbrella stays open so the original evidence stays attached to it. #1049 I assessed and did not start. The design is complete in the write-substrate contract and none of it exists: adoption-pending appears 37 times in the devlog and zero times in src. What is missing is not an adoption branch but the whole publication protocol - a complete-database temp publisher, atomic no-clobber publication, fsync ordering, and the positive-authority gate. That is crash-safety machinery for durable state in the user's Codex home, where a subtly wrong publication corrupts an install rather than failing a test. It is implemented completely with its fixture matrix or not at all, and squeezing a partial version into a wave beside unrelated fixes is the worst of the options.
Three factual fixes and one scoping fix, all from the review of this phase. The symbol name was wrong - codexWriteCoordinationEligibility, not decideCoordination, which greps to nothing. In a note written specifically so the next attempt does not have to rediscover the shape, that is the error that actually costs someone time. #1942 claimed nothing verifies the post-install tree can boot. Verification does exist; it is detect-only and runs after the old install is already gone, which is a narrower claim and a worse defect. Corrected on the issue. The #1049 gap is bigger than I recorded: the contract forbids opening a missing final path with create:true, and transition-state.ts does exactly that, so the publisher work rewrites the create path every clean install uses rather than a legacy branch. That widens the blast radius and makes the defer more clearly right. The defer itself held, but the monolith framing did not. The temp-database publisher for the ordinary clean row is a prerequisite that stands on its own and removes the zero-byte first-create window for everyone, so the remaining work is two reviewable phases rather than one.
The errata section recorded the correction, but the narrative still said decideCoordination - so grepping the name a future reader would try still hit the wrong line first, with the fix seventy lines further down. Correcting a name only in an appendix is the failure mode the errata was written to prevent.
The WP5 outcome named four trackers across three sections; this puts them in one table so the next person does not have to reassemble the split from prose. Worth stating explicitly: the two open items are unstarted for different reasons. #1942 is ordinary work nobody has done. #1049 is unstarted because doing it right means rewriting the coordinator create path every clean install already uses - a blast-radius decision rather than a backlog position, and the kind of distinction that gets lost when an issue just sits there.

Add blank lines before the new headings.
markdownlint-cli2 reports MD022 because these headings follow the preceding paragraphs without a blank line. Insert one blank line before each heading.

Summary
Devlog-only. Records the Wave 5 WP5 outcome: one issue split, one deliberately not started.
#1849 was two defects wearing one number. #1877 stopped the service wrapper
restart-looping against a missing install and shipped in v2.24.0. Nothing has been done
about how the install went missing —
npm install -gis destructive-in-place, andsrc/update/has no staging, snapshot, or rollback anywhere on the path. That half is now#1942, and #1849 stays open as the umbrella so the original evidence (107 directories,
zero files, every launcher gone, 1,009 restarts over 89 minutes) stays attached to the story.
Worth being precise about, because the first draft of #1942 was not: verification does exist
(
checkUpdatePackageIntegritybefore the proxy stops,isRealBunBinary, an identity-checked/healthzprobe after restart). It is detect-only and runs after the old install is alreadygone, so a failed probe has nothing left to restore. That is a narrower claim than "nothing
verifies" and a worse defect.
#1049 was assessed and left unstarted, with the reason recorded.
adoption-pendingappears zero times in
src/and 37 times in the write-substrate contract — the design iscomplete and none of it is built. What is missing is not an adoption branch: the contract
forbids opening a missing final path with SQLite
create:true, andtransition-state.tsdoes exactly that today, so the temp-publisher work rewrites the create path every clean
install already uses.
That is crash-safety machinery for durable state in the user's Codex home, where a subtly
wrong publication corrupts an install rather than failing a test. Review did improve the
shape though: there is a standalone prerequisite — the complete-temp-database publisher plus
atomic no-clobber publication, ordinary clean row only — that ships value on its own (it
removes the visible zero-byte window on first create for every user) and splits the remaining
work into two reviewable phases instead of one.
