[Feature]: [P3] Mobile distribution tail: E1d/E1e remainders plus untracked E2c/E2d/E3; resume-or-pause needs owner decision D-3

Scope widened by the full repository audit (2026-07-21, findings AUD-019/035/036/037; report at _bmad-output/planning-artifacts/reviews/full-repository-audit-2026-07-21/). This issue is now the tracking home for the whole remaining mobile-distribution tail, not just E1d/E1e. Backlog row mobile-e1d-e1e-stream updated to match.

What the audit verified

• E1a/E1b/E1c: done as claimed (src/platform/ exists, PWA gating on native mode shipped, --mode native works).
• E1d: not done: no docs/distribution.md, and the public repo has zero git tags, so the PUBLIC_REF "tag" contract has nothing to point at. Consequence: verticopolis-mobile/PUBLIC_REF (f52489e1, 2026-07-07) is 1,099 commits behind main and predates E1a-E1c: a tree built at that pin has no platform seam at all (AUD-019).
• E1e: diverged without a recorded decision (AUD-036): the /?src=twa marker that the TWA README and story E2a treat as load-bearing has no consumer; the shipped Vercel analytics has no platform dimension, so TWA sessions classify as web with or without the marker. Resolving this folds into the analytics-platform ruling (audit §19, D-1).
• E2a: done as claimed (mobile PR #2; deliverables match the story).
• E2b: correctly blocked (no assetlinks.json; production serves 404 as expected pre-E2b).
• E2c/E2d, E3a-E3d: not started and previously tracked nowhere (AUD-037); the mobile repo's ledger is empty and no workflows exist, while mobile CLAUDE.md's layout section describes them as present (AUD-035, doc true-up rides the first PR of whichever path is chosen).

Blocked on

Owner decision D-3 (audit §19): resume the mobile epic or formally pause it. Until then this issue tracks the tail; no story below E1d should start. First PR on resume: PUBLIC_REF bump + E1d tag + mobile CLAUDE.md truth pass.

Acceptance (for closing this issue)

Either (a) D-3 = pause: epics doc and mobile CLAUDE.md marked paused/planned-vs-present, this issue closes as the record; or (b) D-3 = resume: each remaining story gets its own row/issue per the mirror convention and this issue closes in favor of them.

Start with the audit report at _bmad-output/planning-artifacts/reviews/full-repository-audit-2026-07-21/ and the mobile CLAUDE.md layout section, then review the D-3 owner decision. Work cannot begin until the mobile epic is resumed or paused; on resume, the first PR must address PUBLIC_REF, the E1d tag, and the documentation truth pass. Close this tracker only after the pause or resume acceptance conditions are recorded.
