+# GStack 2.0 status
+
+**Current state: BASELINED AND MAPPED — NOT IMPLEMENTED, NOT VERIFIED, NOT
+DONE.**
+
+This checklist separates evidence capture from delivery so generated plans or
+passing narrow tests cannot be mistaken for a completed rewrite.
+
+## Phase checklist
+
+- [x] Freeze the audit base at
+  `bb57306d98c97011b0919c6132705a15b1579781`.
+- [x] Record template/output/section, line, byte, repeated-preamble, catalog,
+  host, and installer-discovery baselines.
+- [x] Capture the baseline command logs without relabeling pre-existing
+  failures as passes.
+- [x] Flatten and reconcile every frozen open issue/PR snapshot into one
+  deterministic map (755 unique items from 1,184 endpoint records).
+- [x] Trace all 16 required PRs to their detail snapshots, changed-file
+  snapshots, component, judgment module, and replacement-test contract.
+- [ ] Review and approve the GStack 2.0 architecture and migration contract.
+- [ ] Convert heuristic backlog dispositions into accepted product/engineering
+  decisions. `NEEDS_EVIDENCE` is intentionally the majority disposition.
+- [ ] Implement the consolidated judgment modules and runtime components.
+- [ ] Implement the replacement contract tests named in `BACKLOG-MAP.json`.
+- [ ] Prove legacy setup migration and standard-installer discovery without
+  root/nested skill shadowing.
+- [ ] Prove behavior and safety parity across all 10 generated hosts.
+- [ ] Re-run the broad, Windows-safe, design, and iOS suites with complete
+  terminal summaries; separate repaired baseline failures from regressions.
+- [ ] Produce release evidence and make an explicit ship/no-ship decision.
+
+## Evidence index
+
+| Evidence | Path | State |
+|---|---|---|
+| Measured baseline | [`BASELINE.md`](./BASELINE.md) | Recorded |
+| Baseline command results and failures | [`TEST-EVIDENCE.md`](./TEST-EVIDENCE.md) | Recorded; baseline is not green |
+| Deterministic backlog generator | [`../../scripts/gstack2/generate-backlog-map.ts`](../../scripts/gstack2/generate-backlog-map.ts) | Implemented and locally validated |
+| Complete mapped backlog | [`BACKLOG-MAP.json`](./BACKLOG-MAP.json) | Generated from frozen snapshots |
+| Baseline logs | `/tmp/gstack2-baseline-logs/` | External/ephemeral audit evidence |
+| time-attack snapshots | `/tmp/gstack2-{open-items,open-prs,label}-pages.json` | External/ephemeral frozen input |
+| garrytan snapshots | `/tmp/gstack2-upstream-{open-items,open-prs,label}-pages.json` | External/ephemeral frozen input |
+| Required PR evidence | `/tmp/gstack2-port-prs/{610,...,2189}{,-files}.json` | External/ephemeral frozen input |
+
+## Interpretation rules
+
+- `PORT_JUDGMENT` means “port the decision/policy with a replacement test,”
+  not “apply the upstream patch verbatim.”
+- `FIX_IN_GSTACK_2` still requires a reproduced defect.
+- `NEEDS_EVIDENCE`, `DEFER_COMMUNITY`, and
+  `SUPERSEDED_BY_CONSOLIDATION` remain review decisions, not closed GitHub
+  items. The generator performs no external mutation.
+- The heuristic map is deterministic triage. Title-first and narrow body rules
+  make it auditable, but human approval is still required before implementation
+  or upstream disposition changes.
