# Status — where the project actually is

> **Populated by phase 4 — not yet written.** Phase 4 owns **149 of the 275 surveyed markdown files**,
> by far the largest extraction job in the chain. Until then, open work is spread across five ledgers
> that do not reference each other.

## Planned contents

| File | Covers |
| --- | --- |
| `implemented.md` | The overlay: `product/`'s 14 business areas → build state. `product/` itself stays untouched |
| `backlog.md` | Every open item as `BL-###`, triaged, each carrying its origin id |
| `backlog-closed.md` | Items confirmed done, with what closed them |
| `decisions.md` | The distilled decision log from the whole phase chain |

## The five ledgers phase 4 reconciles

| Source | Size | Note |
| --- | --- | --- |
| [frontend/requests/for-backend.md](../../dev/shared-working-context/frontend/requests/for-backend.md) | 67 REQs, 104 K | Append-only; dispositions must be re-checked, not copied |
| [hardening/issues.md](../../dev/post-phase/hardening/issues.md) | 18 items | **18 of 18 unticked**, last touched 2026-07-17 — while four later chains shipped. Re-verify each against code (**C-10**) |
| `reports/*.md` "Follow-ups for later phases" | 53 reports | Every report has one. Confirmed present in all 53 |
| `backend/handoff/*.md` | 22 files | Deferrals with pull-triggers |
| [product/notes/open-questions.md](../../product/notes/open-questions.md) + [manual-testing/](../../dev/manual-testing/) ×2 | — | Business questions and two raw human feedback notes |

Plus [mocks-registry.md](../../dev/shared-working-context/reports/mocks-registry.md) (75 K) — the seam-by-seam
mock/real status that `implemented.md` needs, and the only file that tracks it.

## Where decisions come from

Every `dev/phases/*` prompt shares a fixed structure, and **§5 "Critical rules you must not get wrong"**
is the section that states constraints *not visible in the code*. Verified present in all 32 prompts —
that is the raw material for `decisions.md`. See [the inventory](../_plan/inventory.md).
