UI:
- Menu avatar dropdown: 'Importar de Jira' -> 'Jira' (renombrado).
- ImportJiraModal.tsx eliminado. Sustituido por JiraModal.tsx con Mantine Tabs:
* 'Importar de Jira': UI heredada del modal anterior intacta.
* 'Comprobar columnas': nueva. Lista cards linked y muestra desincronizadas
(kanban col vs Jira status actual). Por cada row: kanban col + expected jira
status + jira status real. Checkbox multi-select + boton 'Sincronizar' que
empuja Jira al status correcto (kanban gana).
Backend:
- GET /api/jira/check-columns: walk cards.jira_key != ''. Por cada uno GET
/rest/api/3/issue/{key}?fields=status. Compara status real vs status_map.
Devuelve {rows[], total, mismatches, in_sync, status_map, reverse_map}.
- POST /api/jira/reconcile-columns {card_ids[], direction:'kanban-wins'}:
reusa jiraHandler.transitionToStatus para empujar cada issue al status del
status_map de su columna kanban actual + actualiza cards.jira_last_status.
- Helper listLinkedCardsForCheck en jira_import.go.
Direction='kanban-wins' default. Reverse direction (jira-wins) no soportado
por ahora: mover cards desde el server tiene efectos colaterales (eventos,
notificaciones, timers) que no quiero disparar masivos sin pensar.
Bug: handleMoveCard solo emitia board.invalidated. Dispatcher mapeaba a
update() (PUT summary/description/labels) NUNCA a transition(), asi que
mover una card en kanban no transicionaba su Jira issue de columna. Solo
los labels reflejaban el cambio.
Fix backend (handlers.go):
- handleMoveCard ahora lee column_id antes del MoveCard. Si la card crusa
columnas (prev != new) publica 'card.moved' antes de 'board.invalidated'.
El dispatcher reconoce 'card.moved' y ejecuta transition() -> Jira status
cambia + labels sincronizan.
- Reorder dentro de la misma columna sigue como antes: solo board.invalidated
para refetch del cliente sin tocar Jira.
- nuevo helper db.lookupCardColumnID(cardID).
UX frontend (JiraSyncIndicator):
- Polling adaptativo: 5s steady, 1s mientras inflight=true. El usuario VE
el yellow durante el sync.
- Listener de window CustomEvent 'kanban-card-moved' (cardId match) que
fuerza un refetch inmediato (~150ms) tras drop. App.tsx dispara el evento
tras api.moveCard resolve. Yellow visible casi instantaneo en lugar de
esperar al proximo tick steady.
Subcomando 'kanban backfill-jira':
- --batch-size N --pause-sec S: procesa N cards entre pausas para no saturar Jira REST.
- --limit N: cap total.
- --column NAME: filtro case-insensitive por columna kanban.
- --dry-run: lista candidatos + counts por columna sin tocar Jira.
Walk: cards con jira_key vacio, no borradas, no archivadas, ORDER BY created_at ASC.
Por cada card: jiraHandler.Handle(card.created event) que crea issue + transition al
status del status_map + labels. Tras success/failure updateCardJiraSync persiste
jira_last_status, jira_last_sync_at, jira_last_error.
Ejecutado contra Jira DATA project: 127 issues creadas (DATA-276..DATA-402), 0 fail.
Distribucion final:
Done: 85 (HECHO)
In Progress: 18 (HACIENDO 7 + Bloqueadas 11, las ultimas con label 'blocked')
IMPLEMENTADO: 14 (PNDNT FEEDBACK)
To Do: 6 (DEUDA TECNICA)
CREADO: 4 (IDEAS)
Backend:
- migration 018: cards.jira_last_status / sync_at / error (estado persistido del ultimo
sync para render UI sin polling Jira).
- Dispatcher: sync.Map inflight para 'yellow' realtime + persistencia de exito/fallo
en cards tras cada dispatch attempt.
- GET /api/cards/{id}/jira-sync: devuelve {jira_key, last_status, last_sync_at,
last_error, inflight, issue_url} para el tooltip del indicador.
- GET /api/jira/issues: lista issues del board 33 con flag already_imported +
mapped_column_id (reverse status_map). Filtros include_imported, limit.
- POST /api/jira/import: multi-key. Cada issue -> CreateCard + setCardJiraKey +
seed jira_last_status. Cae en columna mapeada por status, o en fallback_column_id.
ADF de description extraido a texto plano.
Frontend:
- JiraSyncIndicator: dot gris/amarillo/verde/rojo bajo IconDotsVertical de cada card.
Mantine HoverCard con jira_key, status, last_sync, last_error, link 'Abrir en Jira'.
Poll cada 10s, refresh-tick opcional.
- KanbanCard: agrupa menu + indicator en Stack vertical (indicator debajo de los 3 dots).
- ImportJiraModal: modal admin con tabla de issues. Checkbox por fila, filtro por texto,
toggle 'mostrar ya importadas', Select de columna fallback. Tras import recarga board.
- App.tsx: nueva entrada de menu 'Importar de Jira' (admin) y ImportJiraModal mounted.
Backend tests siguen verdes (test mock cubre transitions endpoints).
Frontend pnpm build OK.
- jiraConfig: campos IssueType + LabelsMap (kanban col -> labels Jira). Default
IssueType='Tarea Tecnica' (DATA project no tiene Task).
- create(): usa c.IssueType y aplica labels iniciales. Despues del POST /issue
ejecuta transitionToStatus para mover la card recien creada al status del
status_map, asi no aterriza en el initial workflow status (CREADO o To Do)
sino donde toca segun la columna kanban.
- update() y transition(): aplican labels en cada sync (PUT replaces array).
Card que sale de Bloqueadas pierde el label 'blocked' automaticamente.
- transitionToStatus: helper compartido entre create() y transition().
- seed-jira-data: inyecta status_map por defecto para nuestras 6 columnas
(HACIENDO -> In Progress, PNDNT FEEDBACK -> IMPLEMENTADO, HECHO -> Done,
IDEAS -> CREADO, DEUDA TECNICA -> To Do, Bloqueadas -> In Progress) y
labels_map (Bloqueadas -> ['blocked']).
- modules_test: mock Jira tambien responde /transitions endpoints.
Cambios:
- jiraConfig: nuevo campo BoardID. TestConnection valida que board.location.projectKey
coincide con ProjectKey declarado. Refuse mismatched scopes so a typo in
project_key cannot create issues in the wrong project.
- backend/seed_jira.go: subcomando 'kanban seed-jira-data' lee credenciales
desde pass (jira/anjana/{email,api-token,domain}) e inserta module row con
kind=jira, project_key=DATA, board_id=33, event_filter sensible. Idempotente
(upsert por name). status_map vacio por defecto (operator lo edita por UI).
- main.go: wire del nuevo subcomando.
Requiere KANBAN_MODULE_KEY env var para encriptar/desencriptar config. El
servidor que ejecuta el dispatcher debe usar el mismo valor.
Net-new capacidades recuperadas del WIP stash que el merge notif no traia:
- mint-token CLI subcommand: 'kanban mint-token --user <id> --name <pc>' genera token bearer
para configurar Claude Code u otros clientes MCP HTTP sin tocar la UI.
- executeToolAs(db, name, input, actor): variante actor-aware de executeTool. El dispatcher
HTTP /mcp pasa el user_id resuelto del bearer token; tools per-user (add_comment,
delete_comment) lo usan como autor sin que el llamante pueda forjarlo.
- get_card tool: lookup por id o seq_num. Devuelve Card completa.
- delete_comment tool: borra card_message; solo el autor original (validado en DB).
executeTool() sigue siendo el wrapper legacy sin actor para chat WS.
Script vivia solo en rama issue/notifications-realtime y se perdio al
hacer checkout master para el branch 0128. Es self-contained (no toca
otros archivos de esa rama). Permite ./control.sh para gestionar
backend (WSL) + frontend Vite (Windows).
review findings:
- MessageBody: only http(s) and relative paths allowed for links;
data:image/* allowed for inline images. Rejects javascript:,
data:text/html, vbscript: which would execute via <a href>.
Unsafe matches fall back to plain text.
- files.go: remove unused fileID var generated then discarded.
- migration 014_card_files: tabla con soft-delete + index activo
- handlers POST/GET/DELETE en backend/files.go
- routes /api/cards/{id}/files, /api/files/{id}

Anade tres capas sobre el reporte diario del issue 0093:
1) Bocadillo del agente: cuadro azul encima de "Tareas hechas" con un
resumen en lenguaje natural (max 4 frases) generado por claude -p
sobre el JSON del reporte. Botones Regenerar e icono Settings.
2) Settings del prompt: modal con textarea editable para el template
del agente (key=daily_report_prompt). Compartido por todos los
usuarios. Boton Restablecer por defecto.
3) PDF descargable: boton que abre ventana nueva con HTML imprimible
(estilo A4, KPIs filtrados, tabla con enlaces absolutos por card).
Permite compartir el listado de tareas hechas con los solicitantes.
Backend:
- Migration 013 anade tablas daily_summaries y settings; seed del
prompt por defecto en castellano.
- daily_summary.go con GetSetting/SetSetting, GetDailySummary/Upsert,
runClaudePrompt (envuelve claude -p) y GenerateDailySummary que
orquesta DailyReportFor + plantilla + claude + persist.
- Nuevos endpoints:
* GET /api/reports/daily/summary
* POST /api/reports/daily/summary
* GET /api/settings/{key}
* PUT /api/settings/{key}
Frontend:
- api.ts: getDailySummary, generateDailySummary, getSetting, setSetting.
- DailyReport.tsx: estado de summary, settingsOpen, promptDraft,
filterRequester, filterAssignee, filteredDoneCards, exportPDF.
- Bocadillo con IconSparkles + IconRefresh + IconSettings.
- Modal de prompt con Guardar/Cancelar/Reset.
- Filtros Select por solicitante y asignado encima de la tabla.
- exportPDF abre window.open con HTML self-contained que incluye
enlaces ${origin}/?card=${id} y window.print() automatico.
E2E nuevo (daily-summary-pdf.spec.ts): CRUD del setting, GET summary
shape, presencia del boton PDF/Settings/Regenerar en el modal. No
invoca claude real (binario externo, no disponible en CI).
Suite completa 11/11 pasa.
Adds a daily report dashboard accessible by clicking a day number in the
calendar view. Renders inside a full-width modal (90% width).
Backend (new file backend/reports.go):
- Type DailyReport with KPIs, rankings, done_cards list, reopened cards,
3-bucket stale list (7/14/30d), lead time avg+p50+p95, 24-hour
movement histogram, deadlines met/missed list, tag distribution and
archived count.
- DB.DailyReportFor(date, tz) uses Europe/Madrid by default; computes
[start,end) in local time, converts to UTC and queries:
* cards.completed_at in range -> done list
* card_events kind=created in range -> created counts
* card_column_history.entered_at in range -> moves + hourly
* previousColumnWasDone() -> reopened detection
* card_lock_history overlapping the day -> blocked_ms
* stale buckets: open history entries on non-done columns aged >=7d
- New route GET /api/reports/daily?date=YYYY-MM-DD&tz=Europe/Madrid.
Frontend:
- api.ts: DailyReport type + dailyReport(date, tz?) call.
- New component DailyReportView (components/DailyReport.tsx):
* 6 KPI cards (Hechas, Creadas, Movimientos, Bloqueado, Reabiertas,
Deadlines on-time %).
* 4 ranking cards (Top assignees done, Top assignees created,
Top requesters atendidas, Top requesters aportadas).
* Done cards table with click-to-jump (links open the card in board).
* Mantine BarChart with movements per hour.
* Tag chips, reopened list, deadlines list with late_ms, stale buckets.
- CalendarView wraps the day number in UnstyledButton with data-test
attribute and forwards onOpenDailyReport.
- App.handleOpenDailyReport opens modals.open size 90% with the view;
click on a card title closes the modal and jumps to the board with
highlight (reuses existing handleJumpToCard).
Tests (e2e/daily-report.spec.ts):
- Endpoint shape: kpis, done_cards, hourly_moves[24], stale buckets.
- Calendar day click opens the modal with "Reporte diario" title and
KPI labels visible.

The random-pick menu entry is meaningless for done columns — cards there
are already finished and now get auto-archived after 30 days (issue
0092). Gate the Menu.Item on !column.is_done so the action only appears
in active columns.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds an archive layer separate from the trash. Cards in is_done columns
that have been there for more than 30 days are auto-archived on the next
board load (throttled to once every 30 minutes). Archived cards leave
the board but stay in the DB and are listed in a new sidebar drawer
"Hecho (archivo)" below the existing Papelera, with a one-click restore.
Schema (migration 012_card_archived.sql):
- ALTER TABLE cards ADD COLUMN archived_at TEXT;
- NULL = active, ISO timestamp = archived. Independent from deleted_at.
Backend:
- Card.ArchivedAt + JSON; ListCardsWithTime filters archived_at IS NULL.
- New methods: ArchiveCard, UnarchiveCard, ListArchivedCards,
AutoArchiveDoneOlderThan.
- New endpoints: GET /api/archive, POST /api/cards/:id/archive,
POST /api/cards/:id/unarchive.
- handleGetBoard invokes maybeAutoArchive (atomic throttle, 30 min sweep,
30 day cutoff). Errors logged but never block the board response.
Frontend:
- Card type + api.ts add the new field and helpers.
- App.tsx state for archive list, reload, archive/unarchive handlers.
- New sidebar drawer with toggle, count badge, restore button.
- KanbanCard gains an "Archivar" menu item (gated on isDone +
onArchive prop) for manual archiving of any done card.
Tests:
- Playwright e2e/archive.spec.ts: manual archive via menu, drawer
toggle, unarchive. Picks a done card via /api/board introspection so
it stays stable regardless of board state.
- Auto-archive of >30d cards: not under e2e (real time travel needed);
covered by code review of the SQL query and the throttle.

Drag perf measured via new Playwright spec drag-perf.spec.ts which drives
a slow drag across the biggest column (~35 cards) while capturing per-frame
durations via rAF inside the page. Pre-fix metrics in HECHO column:
wrapper-renders=1942 body-renders=N/A
p50=16.7ms p95=83.3ms max=116.7ms (12fps stalls)
Root cause: useSortable inside KanbanCardImpl subscribes to dnd-kit context;
every pointermove during a drag re-renders ALL cards in the SortableContext.
With the old monolithic component, each re-render rebuilt the full Stack +
Menu + 4 Popovers JSX tree — even though no data had changed.
Fix: split KanbanCardImpl into a thin outer (useSortable + Paper wrapper +
sticker overlay handler + style) and a memoed KanbanCardBody (Stack +
sticker overlay + popover state). All popover/requesterDraft local state
lives inside the body now, so its props are stable across drag and
React.memo skips the body work entirely.
Post-fix metrics:
wrapper-renders=1943 body-renders=0
p50=16.7ms p95=16.8ms max=50.0ms (steady 60fps with a single 33ms spike)
E2E thresholds tightened: p50<20, p95<50, max<60, body-renders<5. Regression
in any of these will fail CI.
Probe helpers (_probeRender / _probeBodyRender) are no-ops unless
window._cardRenderProbe is set. Production cost: ~3ns per render call.
Also: `now` clock interval already pauses while dragging (previous commit
e656e8c). `animateLayoutChanges:() => false` kept; it does not visibly
change reorder UX with this codebase.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two issues:
1. "Maximum update depth exceeded" inside Mantine's useMergedRef during
drag. Root cause: the `data` object passed to dnd-kit's `useSortable`
in KanbanCard and KanbanColumn was re-created on every render. Mantine
Paper composes its internal ref with the consumer ref via
useMergedRef, which uses a useCallback whose deps array contains the
refs themselves. Whenever the underlying setNodeRef from useSortable
became unstable (because dnd-kit's internal state churned on data
identity change), the merged ref was reassigned each commit -> setState
inside the ref callback -> next render -> new data identity -> loop.
Wrap the sortable data in useMemo keyed on its real inputs.
2. Drag feels laggy. Each card listens to a 1-second `now` clock that
re-renders the entire board to refresh the "time in column" label.
Pause that interval while a drag is active so dnd-kit's per-pixel
reconciliation does not also re-mount/re-layout every card every
second. Tick resumes the moment the drag ends.
Also move the Select `data` array for the column max-time popover from
an inline expression to a module-level constant; same array identity
across all column instances and renders -> Mantine Combobox stops
re-running its diffing effect for free.

The 32px left drag zone now also closes the sidebar when it is open.
Symmetric behaviour: dwell ≥400ms while dragging closes if open / opens
if closed.
To prevent a drag that starts with the pointer already inside the
sidebar (e.g. dragging a sidebar card itself) from immediately auto-
closing, the close action requires the pointer to have left the strip
at least once after the drag started. So:
- closed + drag-to-edge -> opens (unchanged).
- open + drag a card out, then move the card back to the edge -> closes.
- open + drag a sidebar card directly to the board -> nothing happens.
After a successful toggle the dwell flag resets, so the user must leave
the strip and re-enter to trigger another action.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Add a 32px invisible strip on the left edge of the viewport that
auto-opens the sidebar when the user drags a card and dwells near the
edge for >=400ms. Removes the manual toggle step when moving cards to
sidebar-located columns.
- App.tsx: global mousemove listener while drag is active; 400ms hover
timer; sets navOpen(true) when triggered; cancels on pointer leave or
drag end. No auto-close on drag end (user keeps sidebar open).
- dropzone.css: subtle inset blue glow with pulse animation while
pointer is inside the strip and a drag is active.
- KanbanColumn.tsx: add data-column-id and data-column-location to the
Paper root for stable e2e selectors.
- e2e/sidebar-dropzone.spec.ts: Playwright test driving a slow drag
to the left edge, asserting the strip arms, sidebar opens, and the
card moves to a sidebar column via /api/board.

HistoryModal now receives the board's columns via prop to enrich
history events with column metadata.
Timeline:
- Entries for column moves into a column with is_done=true now render
with a green IconCheck bullet and the kind label "Hecho en columna"
instead of the generic blue arrows / "Mueve a columna". Makes the
card's "done" moments scannable at a glance.
Footer (below the timeline):
- Replaces the single Group-of-badges with a structured table showing
one row per visited column: name, visits (entry count) and total time
in column. DONE columns are flagged with a green check + bold.
- Total locked time keeps the same source (total_locked_ms) but moved
to a header line above the table to declutter.
- Currently-active entry (exited_at=null) contributes now - entered_at
to its row, so the table reflects live time.
App.tsx passes columns from board state when opening the history modal.

Replace the native window.prompt with a Popover that mirrors the deadline
picker pattern: NumberInput + unit Select (minutos/horas/dias/semanas/meses).
The selected unit converts to minutes at save time; the column's stored
unit on the backend stays unchanged (max_time_minutes).
On open the popover pre-selects the largest unit that yields a clean
integer for the current value (e.g. 1440 -> 1 dia, 60 -> 1 hora).
Includes a trash icon to clear the limit and a Guardar button.
data-test selectors added for future e2e:
- column-max-time, column-max-time-input, column-max-time-unit,
column-max-time-save.
Menu label now shows "(N dias)" / "(N semanas)" / etc. instead of "(N min)".

Adds a column-level "Seleccionar Aleatorio" context menu entry that picks
a card at random from the column with a roulette-style highlight
animation that decelerates to the winner.
Selection respects existing filters (uses cardsByColumn which is the
post-filter view) and always excludes locked cards. Menu entry is
disabled when nothing pickable is left.
Implementation:
- KanbanColumn: new Menu.Item with IconDice5; data-test selector for e2e.
- onPickRandom prop wired from KanbanColumn -> App.
- handlePickRandom in App.tsx: cryptographically random winner via
crypto.getRandomValues, 2 full laps + offset, cubic decay 50ms -> 220ms,
follows the active card with scrollIntoView.
- src/styles/roulette.css: .kanban-roulette-active (blue pulse, single
step) and .kanban-roulette-winner (green pulse + scale, ~1.6s).
Imported globally from main.tsx.
Manual verification only (visual timing + needs real cards). Backend
untouched.

Adds column-level max time limit. Cards whose time_in_column_ms exceeds
the limit show a red border + red halo. Columns marked as Done never
trigger the visual regardless of the limit (per spec).
Backend:
- Migration 011_column_max_time.sql adds columns.max_time_minutes
INTEGER NOT NULL DEFAULT 0 (0 = no limit). Aditiva, idempotente.
- Column struct + ColumnPatch + UpdateColumn handle the new field;
negatives clamp to 0; listing query includes it.
- handleUpdateColumn (PATCH /api/columns/:id) accepts max_time_minutes
in the JSON body.
Frontend:
- Column TS interface + UpdateColumnInput updated.
- KanbanColumn context menu: new entry "Tiempo maximo" using
window.prompt for low-friction config; shows current value when >0.
- KanbanCard receives columnOverdue prop calculated from the column
state and card.time_in_column_ms; renders red border (var
--mantine-color-red-6) with 2px width + 2px red halo when overdue.
- data-card-id, data-column-overdue, data-locked attributes on the card
paper element so e2e tests / scripts can query state.
Tests: TestColumnMaxTimeMinutes_Defaults + _Update verify the schema
default, the clamp on negative input, and that updating max_time leaves
other fields untouched.
Visual regression of the red border kept out of automated e2e because
it requires either clock control or real cards aged > N minutes; will be
verified manually after merge.

CardForm: drop pre-fill of requester from logged user; Enter inside the
Autocomplete no longer submits the form (Mantine handles dropdown
selection; arrows + Enter pick option without closing modal). Submit
remains via "Crear" button or Ctrl+Enter from description.
Adds data-field="requester" and data-test="add-card" selectors for stable
e2e queries.
Tests:
- vitest component test (CardForm.test.tsx): empty input, Enter does not
submit, submit only via button. Dropdown arrow nav covered by e2e
(jsdom portal handling is brittle).
- Playwright e2e (requester-input.spec.ts) using new browser capability
group (pw_kanban_login, pw_keyboard_sequence) from registry.
- seed_e2e_user CLI to create deterministic test user against
operations.db (bcrypt via standard backend hash).
Setup additions (frontend/):
- vitest + @testing-library + jsdom devDeps
- @playwright/test devDep + playwright.config.ts
- src/test/setup.ts polyfills jsdom for Mantine (matchMedia,
visualViewport, document.fonts, ResizeObserver)
