Fixes the case where the H1 chip, the pipeline stepper and the manual-changer
dropdown disagreed (e.g. 1043-02-26 on analyst_verified): the status sat between
the canonical 10 and a legacy bucket, so each surface read a different list.
Root fix — ONE authoritative status model + canonicalize the real intermediate
states (chair-approved):
- New mcp-server/.../case_status_model.py — the single registry: ordered
StatusDef list (key/label/description/phase/selectable/terminal/on_enter),
the 5 phases, STATUS_ORDER, phase_of/label_of, and a drift assertion that the
CaseStatus enum matches it. `on_enter` is the seam for a status to *do*
something on entry, declared next to its definition (no dispatcher wired yet).
- models.CaseStatus enum: analyst_verified + research_complete promoted to
first-class canonical statuses (the agents set them — they belong in the
model, not a legacy fallback).
- tools/cases.py: the forward-only STATUS_ORDER guard now derives from the
registry instead of an inline list.
- GET /api/status-model exposes the model so the frontend mirror can be
generated against it.
- web-ui case-status.ts mirrors it: the two intermediates moved from the
legacy map into CASE_STATUSES / PHASES(thinking) / STATUS_LABELS /
STATUS_DESCRIPTIONS; status-badge icons+tones extended. So the chip (status),
stepper (its phase) and dropdown (now includes it) all agree.
Invariants: G2 — collapses the scattered status definitions (enum, inline
STATUS_ORDER, two frontend label maps) onto one backend authority + a documented
frontend mirror; no parallel status list remains. Agent-prompt alignment +
backfill follow in a separate change. py_compile + tsc + eslint clean.
