nocal account connect microsoft runs the PKCE browser flow, reads /me,
upserts the deterministic account row, and persists tokens to Secret
Service as the final connected-state gate. Account IDs are hashed from
the remote subject so reconnect is idempotent, and a secret-store
failure leaves the same coherent state as a disconnect. Ships a
placeholder client ID with NOCAL_MICROSOFT_CLIENT_ID override until a
real Entra registration exists.
Draft the generic SyncProvider/SyncObserver contracts and implement
OAuthTokenBroker: valid access tokens with a five-minute refresh skew,
rotation persisted before use so a new refresh token is never lost,
400/401 refresh rejections erase the secret and surface
AccountDisconnected, and no credential material in error messages.
Read documented Graph v1 calendarView pages for secondary calendars and publish each finite window only after the complete bounded listing validates.
Add schema-v2 per-window event membership so moved-out occurrences are evicted without being mislabeled as remote tombstones, while overlapping windows retain shared instances.
Verified: 18/18 fresh normal, 18/18 -Werror, and 18/18 ASan/UBSan tests.
Add strict /me identity, atomic paged calendar discovery, and resumable primary-calendar v1 delta synchronization through the durable provider cache. Keep opaque continuations on trusted Graph URLs and retain credentials only per operation.
Document that stable Graph v1 delta covers only the primary calendar; secondary calendars still require a v1 reconciliation or beta dependency decision.
Verified: 18/18 normal, 18/18 -Werror, and 18/18 ASan/UBSan tests.
Add bounded token response parsing with refresh-token retention and a cancellable worker-thread libsecret adapter using versioned credential payloads.
Verify CRUD, isolation, cancellation, corruption, unavailable service, redaction, and cleanup against an isolated D-Bus and gnome-keyring Secret Service in normal, warning-as-error, and sanitizer profiles.
Add a bounded libcurl transport with verified TLS, no redirects or retries, sanitized failures, binary-safe requests, and resolved-address enforcement for cleartext loopback traffic.
Add shell-free xdg-open launching and a one-shot IPv4 loopback callback receiver with strict HTTP/query parsing, deadlines, fixed callback path, and RAII cleanup. Token parsing, Secret Service, and Graph remain follow-up phases.
Add a private provider-neutral SQLite WAL cache with transactional migrations, retained raw payloads and tombstones, per-window opaque checkpoints, and reserved outbox/conflict tables.
Verify migrations, permissions, identity invariants, concurrent access, atomic pull-page rollback, and future-schema rejection with deterministic tests. No OAuth, networking, secrets, or Graph synchronization is included yet.
Add a Monday-default --week-start option for every weekday and carry it through domain layout, full and compact rendering, event query windows, print mode, and the interactive TUI.
Preserve byte-compatible Monday output and cover rotated headers, spill dates, invalid input, sanitizer behavior, and live terminal restoration.
Derive session calendars from event metadata and apply one visibility contract to month rendering, appointment focus, and search without filtering persistence writes.
Add keyboard picker coverage, full-model save regression tests, documentation, warning-clean builds, sanitizer verification, and live PTY terminal restoration checks.
