Rework Tasks tab: Chains section, checklist modal, project visibility

2026-07-18T00:14:45+00:00

The flat Tasks-tab atom list was silently dumping every chain step (locked and unlocked) and dormant bucket-pool items in as ordinary undated cards, with no chain/project context and no protection against completing a locked step out of order. - CompleteNativeTask now rejects completing a locked chain task (ErrChainTaskLocked), mapped to 400 in both the widget and web complete-atom handlers. - Chain tasks and dormant bucket items are excluded from the flat atom list; a new "Chains" section shows one card per active/paused chain with the current step and N/M progress. - New chain checklist modal (GET /chains/{id}) lists every position in order with pause/resume/abandon -- the web view originally deferred as Android-only. - Fixed a real bug this surfaced: resuming a paused chain only flipped the status flag, never unlocking the deferred successor, so a chain paused right after a completion stayed stuck forever. SetChainStatus now catches up the deferred advancement on resume, idempotently. - Atom cards gained a project-name chip for general visibility.

Extend chain creation to accept per-task description and priority

2026-07-17T22:46:18+00:00

CreateChain and POST /api/widget/chains previously only took bare title strings, with priority hardcoded to 1 -- narrower than the spec's "an ordered list of task titles/descriptions" API line. Now accepts []models.ChainTaskInput{Content, Description, Priority} per position, priority defaulting to 1 when omitted.

Implement linear task chains and recurring maintenance buckets

2026-07-17T22:22:37+00:00

Backend, web timeline, and Android widget wiring for the last two unimplemented items from doot-future-task-scheduling-ideas. Chains: task_chains table + chain_id/chain_position/chain_unlocked on native_tasks (migration 026), WIP-limit-1 advancement hooked into CompleteNativeTask, locked tasks excluded from all date-based queries, 5 new /api/widget/chains* endpoints, an N/M position badge on web and Android widget rows. Buckets: maintenance_buckets table + bucket_id/bucket_state/ bucket_last_active_at on native_tasks (migration 027), staleness-then-priority selection scoring, a new RunBucketCycleCheck scheduler loop, 5 new endpoints including the distinct Defer action, a Defer button on web and Android widget rows. Also corrected stale "not yet approved" status headers on the two already-shipped specs this work depended on (labels/projects, budgets/ availability) -- their headers were never updated after implementation.
