## Problem/Motivation `CLAUDE.md` line 19 reads: > Submodules live under `modules/` — currently `campaign_mosaico`. There are **three** submodules, not one: ``` modules/campaign_easy_email/ modules/campaign_emailbuilder/ modules/campaign_mosaico/ ``` Verified against git history — each arrived without touching the line that counts them: | Submodule | Added by | Commit | | --- | --- | --- | | `campaign_mosaico` | [#3615635] | `f1558f5` | | `campaign_emailbuilder` | [#3615636] | `027ac89` | | `campaign_easy_email` | [#3615638] | `d8ce94b` | So the enumeration was correct when written, then went stale twice in succession. **Why this is worse than a typical doc nit.** `CLAUDE.md` is injected into every session in this project. A wrong fact here does not sit quietly in a file nobody opens — it is read aloud at the start of every piece of work and propagates into it. The file already makes this exact argument about its own core-support line, calling staleness there "self-propagating". The same reasoning applies to the sentence directly beside it. The practical failure mode is a session that reads "currently `campaign_mosaico`", takes it as the module inventory, and reasons about a two-submodule change as though the other two do not exist. That is not hypothetical: [#3615656] found `campaign_easy_email.info.yml` still declaring `^11.1` — a submodule missed by [#3615644]'s sweep partly because nothing in the project guide said it was there. ## Proposed resolution **Do not simply update the list to name three.** The enumeration has now gone stale twice, on consecutive submodule additions, which is evidence that the hand-maintained list is itself the defect rather than the particular values in it. [#3615665] would add a fourth (`campaign_grapesjs`), giving it a third chance to go stale before anyone reads this. Prefer a form with no inventory to maintain — the directory is already the authoritative list: > Submodules live under `modules/`, one per composition editor. That is stable across additions and removals, tells a session the organising principle rather than a snapshot, and points at the place where the real answer lives. **Also split the sentence.** Line 19 currently couples the submodule inventory to the start of the core-support statement: > Submodules live under `modules/` — currently `campaign_mosaico`. Core support: `^11.3` (…) These are unrelated facts sharing a line, which is part of why an editor changing one has repeatedly not noticed the other. [#3615656] rewrote the core-support half of this very sentence and left the submodule half wrong. Give them separate sentences, or separate lines. ## Remaining tasks - [ ] Decide between naming all three and dropping the enumeration (the latter is recommended above, but it is the maintainer's call). - [ ] Split the submodule statement from the core-support statement on line 19. - [ ] Check whether `README.md` carries the same stale inventory independently — `CLAUDE.md` and `README.md` have historically stated overlapping facts separately, and [#3615644] found exactly that pattern with the core constraint. ## API changes None. Documentation only, and agent-facing documentation at that — no code, no configuration, no schema. ## Related - [#3615669] is the other open `CLAUDE.md` accuracy issue, covering the `why::` label scope and the not-fixed close-out path. This was filed separately rather than folded in: that issue is already `state::needsReview` with [!23] open, and the subject matter is different — a missing workflow vocabulary versus a factual enumeration going stale. Folding a new concern into an MR under review would reopen it. - Spotted while working [#3615656] (raise the core floor to `^11.3`) and deliberately kept out of that MR, which is a floor raise.
