Phase 16: hardening and release 0.1.0

- TOTP second factor (RFC 6238, secret encrypted under the master key),
  ten hashed single-use recovery codes, two-step login with a pending token
  bound to the client address, account enrolment/disable, admin reset
- tests/security: prompt-injection corpus never acts or creates evidence-free
  beliefs; roles and CSRF on form and API paths; cross-mind isolation
  (demo scenario 5); stored-XSS escaping and CSP across pages; secrets never
  echoed (API, pages, database, archives); hostile archive import; session
  lifecycle and security headers
- OpenAPI 3.1 document generated from the route table, served at
  /api/v1/openapi.json and kept complete by a test
- gosec clean (justified #nosec annotations, cookie/redirect hardening,
  bounded multipart parsing, UUID packing without narrowing conversions);
  govulncheck clean with toolchain pinned to go1.26.8

 ### Added
+- Phase 16 hardening: TOTP second factor with recovery codes and two-step login, administrator 2FA reset, cross-cutting security test suite, OpenAPI 3.1 document served by the daemon and kept complete by a test, gosec and govulncheck clean with the toolchain pinned, cookie and redirect hardening, release notes.
 - Phase 15 study tools: mind snapshots (checksummed JSON archives of full state), forks that share history by reference with remapped ids, deterministic mind comparison, export and hostile-input import, cognitive replay in disabled sandbox minds with exact/approximate/diverged labelling and recorded model responses, and an experiment framework (overrides, stimulus scripts, expectations, exportable results with the subject archive).
 - Phase 14 dreaming: opt-in idle mode with allowed hours, interval and budgets; deterministic memory replay sample, vocabulary-based association of unlinked memories, speculative hypotheses as low-prior beliefs with optional model wording; promotion/rejection review in UI, API and CLI; dreams run in a forbidden capability context so they can never act.
 - Phase 13 integrations: research folder watcher with safe extraction and fingerprints, shallow bare git mirrors with co-change stats, Prometheus/VictoriaMetrics threshold and change detection, HMAC-signed webhooks with replay protection and rate limiting, per-integration health, runs and document ledger in UI/API/CLI, `read_metrics` and `repository.read` capabilities.

 ## Status
 
-Milestone M1 is complete: start, log in, create a mind, shape its personality, configure a model, chat, watch cognitive events live, inspect working memory, the workspace, memories, beliefs and provenance, restart, and continue the same mind. `go test ./tests/m1/` exercises that slice end to end. Phases 9–16 (goals, drives, predictions, metacognition, reflection, consolidation, relationship graph, capabilities, integrations, dreaming, snapshots, replay, experiments, hardening) are in progress; see [PLAN.md](PLAN.md) and [CHANGELOG.md](CHANGELOG.md). Screenshots will be added once the UI stabilises.
+Version 0.1.0: all sixteen phases of [PLAN.md](PLAN.md) are implemented. Highlights beyond the first milestone: goals and motivation, predictions and calibration, metacognition, reflection and consolidation, the relationship graph, the capability and policy layer, integrations (research folder, git, Prometheus, webhooks), dreaming, snapshots and forks, cognitive replay, experiments, export/import, TOTP. See [CHANGELOG.md](CHANGELOG.md), [docs/RELEASE_NOTES.md](docs/RELEASE_NOTES.md) and the API document at [docs/openapi.json](docs/openapi.json) (also served at `/api/v1/openapi.json`).

+## Two-factor authentication
+
+Operators can enable TOTP (RFC 6238) on the account page. The secret is stored encrypted under `NOEMA_MASTER_KEY`; ten single-use recovery codes are stored hashed and shown once. Login becomes two steps: password, then a code exchanged against a five-minute pending token bound to the client address. Administrators can reset a user's second factor from the users page.

+# Noema 0.1.0
+
+First release: every phase of the plan is implemented, tested and documented.
+
+## What you get
+
+- A daemon (`noemad`) hosting many minds, each with identity, personality, configuration, working memory, workspace, memories, beliefs with evidence arithmetic, goals, drives, affect, predictions, self-model, narrative, notifications and an append-only cognitive history.
+- Deterministic attention and executive logic; language models only as replaceable services (OpenAI-compatible, Anthropic, Ollama) with recorded, replayable calls and encrypted secret references.
+- A capability layer that is the only way a mind can act: ALLOW / ASK / DENY policies, approvals bound to exact requests, locked capabilities, tool output treated as data.
+- Integrations: research folder, git mirrors, Prometheus/VictoriaMetrics, signed webhooks.
+- Background cognition: consolidation, reflection, metacognition, dreaming (opt-in, cannot act).
+- Study tools: snapshots, forks sharing history by reference, comparison, export/import, cognitive replay (exact / approximate / diverged), experiments with exportable results.
+- A complete web UI, a CLI (`noemactl`), an OpenAPI document, Prometheus metrics, audit log, roles, sessions, API tokens and TOTP.
+
+## Verification
+
+`go vet`, `go test -race ./...`, staticcheck, gosec (G104 excluded) and govulncheck are clean with Go 1.26.8.
+
+## Known limits
+
+- Replays diverge honestly when retrieval scoring depends on wall-clock recency; a virtual clock for replay is future work.
+- No screenshots yet; the build environment has no browser.
+- Model comparisons in experiments are made by changing role routing between runs; the routing in force is recorded with each result.
+- Embeddings need pgvector; without it retrieval is lexical and structural only.
