The check also runs immediately when the worklog tab regains focus, and is fully visibility-gated (a hidden tab spawns zero `wl`/`herdr` processes). The same pane-title lookup drives the selection list's **in-progress marker**: an item with a matching pane is shown as `in-progress` (marker + Group N) even when its worklog status is still `open`, and loses the marker when the pane closes. See [Hydrator](#hydrator-self-healing-in_progress-claims-wl-0msojlzd9004p8pi). - **Per-request priority (`X-Priority`)** — The proxy's retired fast/cheap operating mode is replaced by a per-request priority. Herdr maps each dispatched work item's priority onto a request priority and conveys it as the pane-launch environment variable `HERDR_REQUEST_PRIORITY`, which the Worklog pi extension turns into the `X-Priority` provider header. See [Request priority](#request-priority-per-request-x-priority). +- **Local capacity reservation** — Before launching a downtime pane the worker claims capacity atomically via `POST /llama/local/reserve`: a granted ticket travels into the pane as `PI_LOCAL_RESERVATION_TICKET` (its first request carries `X-Local-Reservation`), a `429` refusal defers with the proxy's `retry_after_s` and the decision log records the evidence, and an absent/failing endpoint fails open to the pre-reservation polling behaviour. See [Local capacity reservation](#downtime-worker-local-llm-idle-dispatch). - **Work-item pane indicator** — The selection list shows a green circle icon (🟢) in the icon prefix of every item with an open work-item pane in the current workspace: a pane whose title carries the work-item ID (the dispatch pane-title convention preserves the ID as a trailing suffix). The icon appears exactly when such a pane is open and never otherwise (producer's rule, WL-0MV1BWETT005GSUJ) — it is pane existence, not a live agent status. The worklist also records which pi agent pane is attached to each dispatched item — including the dispatched command — persisted to the gitignored `.worklog/agent-panes.json`, shared across worklist panes (used for the hover tooltip). The icon occupies a fixed-width slot so the item-ID column never shifts.

The active stage filter is shown in the header only (` (filtered: <stage>)`) — there is no standalone filter bar or blank chrome row. Heading rows count against the budget, and the below/above-the-fold `▼ more`/`▲ more` indicator rows (WL-0MSG8YXYJ008PWJJ) are reserved in the budget before the visible window is trimmed, so the pane never scrolls the header or top items off the top of the view regardless of row count (see WL-0MSAAON63003N6LO, WL-0MSGTSPXK007POB1). The header line itself is truncated to the terminal width (`cols`) via an ANSI-aware `truncateLine` helper (WL-0MSNI6TQ5003JY1Z), so it always occupies exactly one physical row even in narrow panes (e.g. 40 cols) where the full concatenated header (count + filter + auto-refresh + downtime status) would otherwise wrap and push the pane content downward. -- **Testable core** — All state management, formatting, and keyboard handling is pure logic in `worklist.ts`, fully testable without a terminal. +- **Testable core** — All state management, formatting, and keyboard handling is pure logic in `worklist.ts` and its extracted sibling modules (`worklist.state.ts`, `worklist.navigation.ts`, `worklist.meta.ts`, `worklist.detail.ts`, `worklist.format.ts`), fully testable without a terminal. - **Toast notifications instead of bottom-line status** — Transient status feedback (refresh outcomes, sync outcomes, sent/skipped command feedback, errors) is surfaced via Herdr toast notifications (`herdr notification show`) instead of being appended to the bottom of the pane output. This keeps the rendered pane within the terminal height budget, so the list header and top lines are never pushed off the top of the pane. Toast delivery requires `ui.toast.delivery = "herdr"` in `~/.config/herdr/config.toml`; toasts appear in the bottom-right corner by default.

Each `wl dep list` edge's `status` is passed through on the `BlockerRef` and rendered as an icon + text suffix on the row (a status-less edge renders the ID + title alone). `formatMetadataPanel` appends one `Blocked By <id> — <title> [<status>]` row per blocker at the end of the metadata rows, and `formatDetailContent` renders the SAME rows in the detail-view metadata table (the detail view resolves blockers through the same single-flight + signature-keyed cache, so the two surfaces never spawn duplicate lookups or flicker; a failed lookup yields no rows — fail-open).

Row building is shared with the detail view via `buildMetaRows` (`worklist.meta.ts`), so the two views never drift apart (see WL-0MSAYNVBY006LM9X). **`Blocked By` rows (WL-0MV8EZRDJ001TDA8, flicker fix WL-0MV8Q5X8U004KKAP; detail-view parity and blocker status WL-0MVBMLY2Z0032CYR):** the selected item's active blockers are resolved via `fetchBlockersForItem` (`fetcher.ts`: `wl dep list <id> --json` + `wl show` stage enrichment, filtered with the shared `isActiveBlocker` predicate and parsed with `parseDepListBlockersOutput`), cached per item ID in `runWorklistTui` and **kept across refreshes** — the cache is invalidated per item only when its payload signature (`status`/`stage`/`updatedAt`) changes, so unrelated refresh cycles reuse the resolved rows instead of re-entering the unresolved frame (this was the endless `Blocked By` flicker: `blockerCache.clear()` ran on every refresh); while a re-resolve is in flight the last known value is still rendered (single-flight, no duplicate spawns). Each `wl dep list` edge's `status` is passed through on the `BlockerRef` and rendered as an icon + text suffix on the row (a status-less edge renders the ID + title alone). `formatMetadataPanel` appends one `Blocked By <id> — <title> [<status>]` row per blocker at the end of the metadata rows, and `formatDetailContent` renders the SAME rows in the detail-view metadata table (the detail view resolves blockers through the same single-flight + signature-keyed cache, so the two surfaces never spawn duplicate lookups or flicker; a failed lookup yields no rows — fail-open). The detail-view scroll clamp (`detailScrollDown`) counts the rows so they are reachable when the view scrolls. The `m`/`M` scroll clamp uses the unpadded content height (`metadataPanelContentHeight`) so the offset reaches the true bottom of the panel. - **Command log** — Dispatched commands targeting a work item are recorded in `command-log.ts` before execution; the panel surfaces the last command for `in_progress` items. Recording is fire-and-forget (never breaks dispatch) and the log file is written atomically (see WL-0MSAYNVBY006LM9X). ## Code Freeze diff --git a/packages/herdr/src/fetcher.ts b/packages/herdr/src/fetcher.ts index 9e540bb7..849ff02f 100644 --- a/packages/herdr/src/fetcher.ts +++ b/packages/herdr/src/fetcher.ts @@ -13,8 +13,8 @@ import { join } from 'node:path'; import { existsSync } from 'node:fs'; import { selectWorkItems } from './smart-selection.js'; import { regroupWorkItems } from './grouping.js'; -import { STAGES } from './worklist.js'; -import type { Stage } from './worklist.js'; +import { STAGES } from './worklist.constants.js'; +import type { Stage } from './worklist.constants.js'; import type { AgentState } from './agent-tracker.js'; import { isActiveBlocker } from './hydrator.js'; import { parseDepListBlockersOutput } from './downtime-worker.js'; diff --git a/packages/herdr/src/worklist.detail.ts b/packages/herdr/src/worklist.detail.ts new file mode 100644 index 00000000..65359272 --- /dev/null +++ b/packages/herdr/src/worklist.detail.ts @@ -0,0 +1,235 @@ +/** + * packages/herdr/src/worklist.detail.ts — the detail view's content and the + * markdown Key Files viewer. + * + * Single responsibility: render a work item's detail view — the Related Docs + * table of contents (`formatDetailToC`), the full unpadded content + * (`formatDetailContent`, whose header height is `DETAIL_HEADER_LINES`) and + * the Key Files markdown viewer (`renderFileViewer` + `firstMarkdownKeyFile`). + * No list state, no scrolling, no input handling.

It also improves sync speed, memory safety during large database loads, save-data import handling, and overall stability during heavy activity. +### Features +- Syncing when nothing changed is now instant instead of taking minutes. (WL-0MVK3WRY9009KV6P) +- Downtime work now starts only when capacity is truly free, so jobs no longer stall or silently fall back. (WL-0MVIKRFP0005JDL8) +- Low-priority jobs now stay on the local slot, while urgent work keeps the fast remote route. (WL-0MVNUIW77000VYAX) +- Keeps the game running smoothly by preventing CPU overload during heavy activity. (WL-0MVK0UO3Q002TXW6) +- Unattended background work now runs on remote capacity by default instead of stalling when the local slot is busy. (WL-0MVNUHWH500196K1) +- Local-first work now waits for local capacity instead of failing, and resumes automatically when it frees up. (WL-0MVSI1JMN002CGC0) +- The full test suite now covers all tests, so fewer bugs slip through to release. (WL-0MVG4FF9200346NR) +- Downtime dispatch is now split into smaller, safer modules, making future fixes and improvements to background work more reliable. (WL-0MVF3F9A7000HKP7) +### Bug Fixes +- Worklog sync now accepts commits from the team's shared author, so updates flow again. (WL-0MVMZP6A5005PB66) +- View refreshes stay responsive even during long background syncs. (WL-0MVMSE2S0006L56D) +- Fixed a save-data issue that could cause imports to fail or duplicate entries. (WL-0MVM9E3SV003III0) +- Large database loads now stay within safe memory limits, preventing slowdowns and crashes. (WL-0MVMSE5LN003KCPQ) +- Fixed a rare issue where downtime activities could incorrectly report success instead of failure. (WL-0MVOTIJ2U000JI44) +- Idle leaders now step down so active players can take over, and peers no longer wait 60 minutes for work. (WL-0MVP7QHUB003ZA2A) +- Fixed a bug where running tasks in parallel could wipe shared game files and break the work tracker. (WL-0MVPADZ1Z000FOSG) +- Improved reliability of performance monitoring so lag spikes are detected more consistently. (WL-0MVS5CZFT001GHK9) +- Fixed slow startup times when launching the game repeatedly. (WL-0MVS9Z965006MC4R) +- Fixed a flaky test that could fail during automated checks, keeping builds reliable. (WL-0MVSLXT79008D4X6) +- Critical child items no longer appear twice in the worklist; their parent is shown instead. (WL-0MVN4WESM007T4XI) +- Idle workers now explain why they're not dispatching, and audits no longer get stuck behind the queue. (WL-0MVR8EXR6009F05V) +- Temporary local model congestion now retries automatically instead of ending your turn. (WL-0MVSBF5XZ001H7V7) +- Idle machines now start queued work instead of waiting forever. (WL-0MVPRZU0A000TSWD) +- Agents can now sync worklog data without manual workarounds. (WL-0MVM92MZ50075E6B) +- Work item titles now reliably appear in the footer, even for items from other projects. (WL-0MVGB23MM004X501) + ## v1.0.23 (2026-10-23) > **Release focus:** This release focuses on performance and responsiveness across the app, with faster `wl` commands, quicker tests, and lower CPU use in Herdr panes and the Work Items pane. It also improves GPU scheduling so downtime tasks start promptly and run one at a time, ensures your own dispatched work jumps ahead of background tasks, and fixes several reliability issues including late-joining agent status, test gate failure messages, and long-running AI sessions blocking overnight work. ### Features From 4334c51478a8563e46926b473a09f1e45f929bd6 Mon Sep 17 00:00:00 2001 From: pi <pi@local> Date: Thu, 29 Oct 2026 15:52:32 +0000 Subject: [PATCH 109/109] Regenerate derived version files for v1.0.24 --- src/version.ts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/version.ts b/src/version.ts index 52d42ff6..38a39e06 100644 --- a/src/version.ts +++ b/src/version.ts @@ -1,2 +1,2 @@ // Auto-generated; do not edit. -export const WORKLOG_VERSION = '1.0.23'; +export const WORKLOG_VERSION = '1.0.24';
