+## FINDING-U10 — 🟠 MISSING: CLI parameter reference not in README or getting-started
+
+### Location
+- `README.md` (has CLI examples but no parameter table)
+- `doc/getting-started.md` (same)
+- `code/src/apps/v0/conformallab_cli.cpp` lines 333–340 (source of truth)
+
+### Problem
+
+The CLI app (`conformallab_core`) is the primary non-programmatic entry point
+for the library.  The README shows a few usage examples but no parameter
+reference.  A user running `--help` gets CLI11's auto-generated output, but
+that output is not reproduced anywhere in the documentation.
+
+Current parameters (from `conformallab_cli.cpp`):
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `-i / --input` | *required* | Input mesh (OFF / OBJ / PLY) |
+| `-o / --output` | *(none)* | Output layout OFF file |
+| `-j / --json` | *(none)* | Serialise result to JSON |
+| `-x / --xml` | *(none)* | Serialise result to XML |
+| `-g / --geometry` | `euclidean` | Target geometry: `euclidean` \| `spherical` \| `hyper_ideal` |
+| `-s / --show` | `false` | Open input mesh in interactive viewer |
+| `-v / --verbose` | `false` | Print topology / DOF stats |
+
+### Fix
+
+Add a concise parameter table to `doc/getting-started.md` in the
+"First run — CLI app" section.  The README already shows the most common
+invocations; the table can live in getting-started to avoid README bloat.
+
+### Acceptance criteria
+- [ ] `doc/getting-started.md` has a parameter table matching the source
+- [ ] Each flag has a one-line description and notes the default
+- [ ] Cross-reference to `--help` for the canonical up-to-date list

+## FINDING-U11 — 🟠 ROADMAP: CLI missing three useful parameters + two models
+
+### Location
+`code/src/apps/v0/conformallab_cli.cpp`
+
+### Problem (not a bug — a gap for a future session to fill)
+
+**Missing solver-tuning parameters** (low effort, high value):
+
+The Newton tolerance and iteration limit are hardcoded at their defaults
+(`tol=1e-8`, `max_iter=200`).  Any user who wants to solve a stiff mesh
+more carefully or stop early has to recompile.
+
+```bash
+# Not yet possible:
+./conformallab_core -i hard_mesh.off -g euclidean --tol 1e-12 --max-iter 1000
+./conformallab_core -i quick_check.off --tol 1e-4 --max-iter 20
+```
+
+**Missing geometry modes** (medium effort):
+
+The two Phase-9a functionals are not reachable from the CLI at all:
+
+```bash
+# Not yet possible — needs run_cp_euclidean() + run_inversive_distance() helpers:
+./conformallab_core -i mesh.off -g cp_euclidean
+./conformallab_core -i mesh.off -g inversive_distance
+```
+
+CP-Euclidean (`Discrete_circle_packing.h`) and Inversive-Distance
+(`Discrete_inversive_distance.h`) are fully implemented in the library and
+exposed via the CGAL public API, but a CLI user cannot reach them.
+
+### Suggested implementation (for a future session)
+
+1. **`--tol <double>` and `--max-iter <int>`:** one `app.add_option` each,
+   thread through all three `run_*` functions.  ~15 lines.
+
+2. **`-g cp_euclidean` and `-g inversive_distance`:** add two new
+   `run_cp_euclidean()` / `run_inversive_distance()` helpers following
+   the existing `run_euclidean()` pattern.  ~60 lines each.  Add to the
+   `-g` `CLI::IsMember` list.  Register the two new geometry strings in
+   the dispatch block.
+
+3. **Update README + getting-started** to list all five geometry modes.
+
+### Effort estimate
+- `--tol` + `--max-iter`: ~30 min
+- Phase-9a CLI exposure: ~2 hours (mostly copy-paste + adaptation)
+- Tests: add two CLI smoke tests (geometry converges on tetrahedron)
+
+### Acceptance criteria (when implemented)
+- [ ] `--tol` and `--max-iter` are accepted and forwarded to all three/five solvers
+- [ ] `./conformallab_core -i mesh.off -g cp_euclidean -o out.off` works
+- [ ] `./conformallab_core -i mesh.off -g inversive_distance -o out.off` works
+- [ ] `--help` output lists all five geometry modes
