fix: suppress typing flicker on queue auto-flush and dedup user bubble on bootstrap race

Adds prometheus_query (instant PromQL) and prometheus_query_range
(time-range) tools. Includes credential spec, /-/ready health check,
unit tests, and docs.

Optional Bearer token and Basic auth via env vars
(PROMETHEUS_TOKEN, PROMETHEUS_USERNAME/PASSWORD).

Fixes #6945.

 ## Overview
 
-Hive is a runtime harness for AI agents in production. You describe your goal in natural language; a coding agent (the queen) generates the agent graph and connection code to achieve it. During execution, the harness manages state isolation, checkpoint-based crash recovery, cost enforcement, and real-time observability. When agents fail, the framework captures failure data, evolves the graph through the coding agent, and redeploys automatically. Built-in human-in-the-loop nodes, browser control, credential management, and parallel execution give you production reliability without sacrificing adaptability.
+OpenHive is a zero-setup, model-agnostic execution harness that dynamically generates multi-agent topologies to tackle complex, long-running business workflows without requiring any orchestration boilerplate. By simply defining your objective, the runtime compiles a strict, graph-based execution DAG that safely coordinates specialized agents to execute concurrent tasks in parallel. Backed by persistent, role-based memory that intelligently evolves with your project's context, OpenHive ensures deterministic fault tolerance, deep state observability, and seamless asynchronous execution across whichever underlying LLMs you choose to plug in.
+
+## Features
+
+- ✅ Multi-Agent Coordination for parallel task execution 
+- ✅ Graph-based execution for recurring and complex processes 
+- ✅ Role-based memory that evolves with your projects 
+- ✅ Zero Setup - No technical configuration required
+- ✅ General Compute Use and Browser Use with Native Extension 
+- ✅ Custom Model Support

-## System Prompt Tips for Browser Nodes
+## Pick the right reading tool
+
+**`browser_snapshot`** — compact accessibility tree of interactive elements. Fast, cheap, good for static or form-heavy pages where the DOM matches what's visually rendered (documentation, simple dashboards, search results, settings pages).
+
+**`browser_screenshot`** — visual capture + metadata (`cssWidth`, `devicePixelRatio`, scale fields). Use this when `browser_snapshot` does not show the thing you need, when refs look stale, or when visual position/layout matters. This often happens on complex SPAs — LinkedIn, Twitter/X, Reddit, Gmail, Notion, Slack, Discord — and on sites using shadow DOM, virtual scrolling, React reconciliation, or dynamic layout.
+
+Neither tool is "preferred" universally — they're for different jobs. Start with snapshot for page structure and ordinary controls; use screenshot as the fallback when snapshot can't find or verify the visible target. Activate the `browser-automation` skill for the full decision tree.
+
+## Coordinate rule
+
+Every browser tool that takes or returns coordinates operates in **fractions of the viewport (0..1 for both axes)**. Read a target's proportional position off `browser_screenshot` ("~35% from the left, ~20% from the top" → `(0.35, 0.20)`) and pass that to `browser_click_coordinate` / `browser_hover_coordinate` / `browser_press_at`. `browser_get_rect` and `browser_shadow_query` return `rect.cx` / `rect.cy` as fractions. The tools multiply by `cssWidth` / `cssHeight` internally — no scale awareness required. Fractions are used because every vision model (Claude, GPT-4o, Gemini, local VLMs) resizes/tiles images differently; proportions are invariant. Avoid raw `getBoundingClientRect()` via `browser_evaluate` for coord lookup; use `browser_get_rect` instead.

+## System prompt tips for browser nodes
 
 ```
-1. Use browser_snapshot() to read page content (NOT browser_get_text)
-2. Use browser_wait(seconds=2-3) after navigation for page load
-3. If you hit an auth wall, call set_output with an error and move on
-4. Keep tool calls per turn <= 10 for reliability
+1. Start with browser_snapshot or the snapshot returned by the latest interaction.
+2. If the target is missing, ambiguous, stale, or visibly present but absent from the tree,
+   use browser_screenshot to orient and then click by fractional coordinates.
+3. Before typing into a rich-text editor (X compose, LinkedIn DM, Gmail, Reddit),
+   click the input area first with browser_click_coordinate so React / Draft.js /
+   Lexical register a native focus event, then use browser_type_focused(text=...)
+   for shadow-DOM inputs or browser_type(selector, text) for light-DOM inputs.
+4. Use browser_wait(seconds=2-3) after navigation for SPA hydration.
+5. If you hit an auth wall, call set_output with an error and move on.
+6. Keep tool calls per turn <= 10 for reliability.
 ```

+          - ``cursor.json`` is deliberately NOT copied. The worker
+            should start fresh at iteration 0; copying the queen's
+            cursor would make the worker think it had already done
+            work.
+          - The queen's ``meta.json`` is copied but the AgentLoop
+            immediately rebuilds ``system_prompt`` from the worker's
+            own context post-restore (see agent_loop.py:533-535), so

+"""Per-colony SQLite task queue + progress ledger.
+
+Every colony gets its own ``progress.db`` under ``~/.hive/colonies/{name}/data/``.
+The DB holds the colony's task queue plus per-task step and SOP checklist
+rows. Workers claim tasks atomically, write progress as they execute, and
+verify SOP gates before marking a task done. This gives cross-run memory
+that the existing per-iteration stall detectors don't have.
+
+The DB is driven by agents via the ``sqlite3`` CLI through
+``execute_command_tool``. This module handles framework-side lifecycle:
+creation, migration, queen-side bulk seeding, stale-claim reclamation.
+
+Concurrency model:
+- WAL mode on from day one so 100 concurrent workers don't serialize.
+- Workers hold NO long-running connection — they ``sqlite3`` per call,
+  which naturally releases locks between LLM turns.
+- Atomic claim via ``BEGIN IMMEDIATE; UPDATE tasks SET status='claimed'
+  WHERE id=(SELECT ... LIMIT 1)``. The subquery-form UPDATE runs inside
+  the immediate transaction so racers either win the row or find zero
+  affected rows.
+- Stale-claim reclaimer runs on host startup: claims older than
+  ``stale_after_minutes`` get returned to ``pending`` and the row's
+  ``retry_count`` increments. When ``retry_count >= max_retries`` the
+  row is moved to ``failed`` instead.
+
+All writes go through ``BEGIN IMMEDIATE`` so racing readers see
+consistent snapshots.

 Follow these rules for reliable, efficient browser interaction.
 
-## Reading Pages
-- ALWAYS prefer `browser_snapshot` over `browser_get_text("body")`
-  — it returns a compact ~1-5 KB accessibility tree vs 100+ KB of raw HTML.
-- Interaction tools (`browser_click`, `browser_type`, `browser_fill`,
-  `browser_scroll`, etc.) return a page snapshot automatically in their
-  result. Use it to decide your next action — do NOT call
-  `browser_snapshot` separately after every action.
-  Only call `browser_snapshot` when you need a fresh view without
-  performing an action, or after setting `auto_snapshot=false`.
-- Do NOT use `browser_screenshot` to read text — use
-  `browser_snapshot` for that (compact, searchable, fast).
-- DO use `browser_screenshot` when you need visual context:
-  charts, images, canvas elements, layout verification, or when
-  the snapshot doesn't capture what you need.
-- Only fall back to `browser_get_text` for extracting specific
-  small elements by CSS selector.
+## Pick the right reading tool
 
-## Navigation & Waiting
-- `browser_navigate` and `browser_open` already wait for the page to
-  load (`domcontentloaded`). Do NOT call `browser_wait` with no
-  arguments after navigation — it wastes time.
-  Only use `browser_wait` when you need a *specific element* or *text*
-  to appear (pass `selector` or `text`).
-- NEVER re-navigate to the same URL after scrolling
-  — this resets your scroll position and loses loaded content.
+- **`browser_snapshot`** — compact accessibility tree. Fast, cheap, good
+  for static / text-heavy pages where the DOM matches what's visually
+  rendered (docs, forms, search results, settings pages).
+- **`browser_screenshot`** — visual capture + scale metadata. Use when
+  the snapshot does not show the thing you need, when refs look stale,
+  or when you need visual position/layout to act. This is common on
+  complex SPAs (LinkedIn, X / Twitter, Reddit, Gmail, Notion, Slack,
+  Discord), shadow DOM, and virtual scrolling.
+
+Use snapshot first for structure and ordinary controls; switch to
+screenshot when snapshot can't find or verify the target. Interaction
+tools (`browser_click`, `browser_type`, `browser_type_focused`,
+`browser_fill`, `browser_scroll`) wait 0.5 s for the page to settle
+after a successful action, then attach a fresh snapshot under the
+`snapshot` key of their result — so don't call `browser_snapshot`
+separately after an interaction unless you need a newer view. Tune
+with `auto_snapshot_mode`: `"default"` (full tree) is the default;
+`"simple"` trims unnamed structural nodes; `"interactive"` returns
+only controls (tightest token footprint); `"off"` skips the capture
+entirely — use when batching several interactions.
+
+Only fall back to `browser_get_text` for extracting small elements by
+CSS selector.
+
+## Coordinates
+
+Every browser tool that takes or returns coordinates operates in
+**fractions of the viewport (0..1 for both axes)**. Read a target's
+proportional position off `browser_screenshot` — "this button is
+~35% from the left, ~20% from the top" → pass `(0.35, 0.20)`.
+`browser_get_rect` and `browser_shadow_query` return `rect.cx` /
+`rect.cy` as fractions in the same space. The tools handle the
+fraction → CSS-px multiplication internally; you do not need to
+track image pixels, DPR, or any scale factor.
+
+Why fractions: every vision model (Claude, GPT-4o, Gemini, local
+VLMs) resizes or tiles images differently before the model sees the
+pixels. Proportions survive every such transform; pixel coordinates
+only "work" per-model and break when you swap backends.
+
+Avoid raw `browser_evaluate` + `getBoundingClientRect()` for coord
+lookup — that returns CSS px and will be wrong when fed to click
+tools. Prefer `browser_get_rect` / `browser_shadow_query`, which
+return fractions.
+
+## Rich-text editors (X, LinkedIn DMs, Gmail, Reddit, Slack, Discord)
+
+Click the input area first with `browser_click_coordinate` or
+`browser_click(selector)` BEFORE typing. React / Draft.js / Lexical /
+ProseMirror only register input as "real" after a native pointer-
+sourced focus event; JS `.focus()` is not enough. Without a real click
+first, the editor stays empty and the send button stays disabled.
+
+`browser_type` does this automatically when you have a selector — it
+clicks the element, then inserts text via CDP `Input.insertText`.
+For shadow-DOM inputs where selectors can't reach, use
+`browser_click_coordinate` to focus, then `browser_type_focused(text=...)`
+to type into the active element. Before clicking send, verify the
+submit button's `disabled` / `aria-disabled` state via `browser_evaluate`.
+
+## Shadow DOM
+
+Sites like LinkedIn messaging (`#interop-outlet`), Reddit (faceplate
+Web Components), and some X elements live inside shadow roots.
+`document.querySelector` and `wait_for_selector` do **not** see into
+shadow roots. But `browser_click_coordinate` **does** — CDP hit
+testing walks shadow roots natively, so coordinate-based operations
+reach shadow elements transparently.
+
+**Shadow-heavy site workflow:**
+1. `browser_screenshot()` → visual image
+2. Identify target visually → pixel `(x, y)` read straight off the image
+3. `browser_click_coordinate(x, y)` → lands via native hit test;
+   inputs get focused regardless of shadow depth
+4. Type via `browser_type_focused` (no selector needed — types into the
+   already-focused element), or `browser_type` if you have a selector
+
+For selector-style access when you know the shadow path:
+`browser_shadow_query("#interop-outlet >>> #msg-overlay >>> p")` —
+returns a CSS-px rect you can feed directly to click tools.
+
+## Navigation & waiting
+
+- `browser_navigate(wait_until="load")` returns when the page fires
+  load. On SPAs (LinkedIn especially — 4–5 seconds), add a 2–3 s sleep
+  after to let React/Vue hydrate before querying for chrome elements.
+- Never re-navigate to the same URL after scrolling — resets scroll.
+- Use `timeout_ms=20000` for heavy SPAs.
+- `wait_for_selector` / `wait_for_text` resolve in milliseconds when
+  the element is already in the DOM — no need to sleep if you can
+  express the wait condition.
+
+## Keyboard shortcuts
+
+`browser_press("a", modifiers=["ctrl"])` for Ctrl+A. Accepted
+modifiers: `"alt"`, `"ctrl"`/`"control"`, `"meta"`/`"cmd"`,
+`"shift"`. The tool dispatches the modifier key first, then the main
+key with `code` and `windowsVirtualKeyCode` populated (Chrome's
+shortcut dispatcher requires both), then releases in reverse order.
 
 ## Scrolling
-- Use large scroll amounts ~2000 when loading more content
-  — sites like twitter and linkedin have lazy loading for paging.
-- The scroll result includes a snapshot automatically — no need to call
-  `browser_snapshot` separately.
 
-## Batching Actions
-- You can call multiple tools in a single turn — they execute in parallel.
-  ALWAYS batch independent actions together. Examples:
-  - Fill multiple form fields in one turn.
-  - Navigate + snapshot in one turn.
-  - Click + scroll if targeting different elements.
-- When batching, set `auto_snapshot=false` on all but the last action
-  to avoid redundant snapshots.
-- Aim for 3-5 tool calls per turn minimum. One tool call per turn is
-  wasteful.
+- Use large amounts (~2000 px) for lazy-loaded sites (X, LinkedIn).
+- Scroll result includes a snapshot — don't call `browser_snapshot`
+  separately.
 
-## Error Recovery
-- If a tool fails, retry once with the same approach.
-- If it fails a second time, STOP retrying and switch approach.
-- If `browser_snapshot` fails → try `browser_get_text` with a
-  specific small selector as fallback.
-- If `browser_open` fails or page seems stale → `browser_stop`,
-  then `browser_start`, then retry.
+## Batching
 
-## Tab Management
+- Multiple tool calls per turn execute in parallel. Batch independent
+  actions together: fill multiple fields, navigate + snapshot,
+  different-target click + scroll.
+- Set `auto_snapshot=false` on all but the last when batching.
+- Aim for 3–5 tool calls per turn minimum.
 
-**Close tabs as soon as you are done with them** — not only at the end of the task.
-After reading or extracting data from a tab, close it immediately.
+## Tab management
 
-**Decision rules:**
-- Finished reading/extracting from a tab? → `browser_close(target_id=...)`
-- Completed a multi-tab workflow? → `browser_close_finished()` to clean up all your tabs
-- More than 3 tabs open? → stop and close finished ones before opening more
-- Popup appeared that you didn't need? → close it immediately
+Close tabs as soon as you're done with them — not only at the end of
+the task. `browser_close(target_id=...)` for one, `browser_close_finished()`
+for a full cleanup. Never accumulate more than 3 open tabs.
+`browser_tabs` reports an `origin` field: `"agent"` (you own it, close
+when done), `"popup"` (close after extracting), `"startup"`/`"user"`
+(leave alone).
 
-**Origin awareness:** `browser_tabs` returns an `origin` field for each tab:
-- `"agent"` — you opened it; you own it; close it when done
-- `"popup"` — opened by a link or script; close after extracting what you need
-- `"startup"` or `"user"` — leave these alone unless the task requires it
+## Login & auth walls
 
-**Cleanup tools:**
-- `browser_close(target_id=...)` — close one specific tab
-- `browser_close_finished()` — close all your agent/popup tabs (safe: leaves startup/user tabs)
-- `browser_close_all()` — close everything except the active tab (use only for full reset)
+Report the auth wall and stop — do NOT attempt to log in. Dismiss
+cookie consent banners if they block content.
 
-**Multi-tab workflow pattern:**
-1. Open background tabs with `browser_open(url=..., background=true)` to stay on current tab
-2. Process each tab and close it with `browser_close` when done
-3. When the full workflow completes, call `browser_close_finished()` to confirm cleanup
-4. Check `browser_tabs` at any point — it shows `origin` and `age_seconds` per tab
+## Error recovery
 
-Never accumulate tabs. Treat every tab you open as a resource you must free.
+- Retry once on failure, then switch approach.
+- If `browser_snapshot` fails, try `browser_get_text` with a narrow
+  selector as fallback.
+- If `browser_open` fails or the page seems stale, `browser_stop` →
+  `browser_start` → retry.
 
-## Shadow DOM & Overlays
+## `browser_evaluate`
 
-Some sites (LinkedIn messaging, etc.) render content inside closed shadow roots that are
-invisible to regular DOM queries and `browser_snapshot` coordinates.
-
-**Detecting shadow DOM**: `document.elementFromPoint(x, y)` returns a zero-height host element
-(e.g. `#interop-outlet`) for the entire overlay area — this is normal, not a bug.
-`document.body.innerText` and `document.querySelectorAll` return nothing for shadow content.
-`browser_snapshot` CAN read shadow DOM text but cannot return coordinates.
-
-**Querying into shadow DOM:**
-```
-browser_shadow_query("#interop-outlet >>> #msg-overlay >>> p")
-```
-Uses `>>>` to pierce shadow roots. Returns `rect` in CSS pixels and `physicalRect` ready for
-`browser_click_coordinate` / `browser_hover_coordinate`.
-
-**Getting physical rect for any element (including shadow DOM):**
-```
-browser_get_rect(selector="#interop-outlet >>> .msg-convo-wrapper", pierce_shadow=true)
-```
-
-**Manual JS traversal when selector is dynamic:**
-```js
-const shadow = document.getElementById('interop-outlet').shadowRoot;
-const convo = shadow.querySelector('#ember37');
-const rect = convo.querySelector('p').getBoundingClientRect();
-// rect is in CSS pixels — multiply by DPR for physical pixels
-```
-Pass this as a multi-statement script to `browser_evaluate`; it wraps automatically in an IIFE.
-Use `JSON.stringify(rect)` to serialize the result.
-
-## Coordinate System
-
-There are THREE coordinate spaces. Using the wrong one causes clicks/hovers to land in the
-wrong place.
-
-| Space | Used by | How to get |
-|---|---|---|
-| Physical pixels | `browser_click_coordinate` | `browser_coords` `physical_x/y` |
-| CSS pixels | `getBoundingClientRect()`, `elementFromPoint` | `browser_coords` `css_x/y` |
-| Screenshot pixels | What you see in the 800px image | Raw position in screenshot |
-
-**Converting screenshot → physical**: `browser_coords(x, y)` → use `physical_x/y`.
-**Converting CSS → physical**: multiply by `window.devicePixelRatio` (typically 1.6 on HiDPI).
-**Never** pass raw `getBoundingClientRect()` values to `browser_hover_coordinate` without
-multiplying by DPR first.
-
-## Screenshots
-
-Screenshot data is base64-encoded PNG. To view it:
-```
-run_command("echo '<base64_data>' | base64 -d > /tmp/screenshot.png")
-```
-Then use `read_file("/tmp/screenshot.png")` to view the image.
-
-Always use `full_page=false` (default) unless you specifically need the full scrolled page.
-
-## JavaScript Evaluation
-
-`browser_evaluate` wraps your script in an IIFE automatically:
-- Single expression (`document.title`) → wrapped with `return`
-- Multi-statement or contains `;`/`\n` → wrapped without return (add explicit `return` yourself)
-- Already an IIFE → run as-is
-
-**Avoid**: complex closures with `return` inside `for` loops — Chrome CDP returns `null`.
-**Use instead**: `Array.from(...).map(...).join(...)` chains, or build result objects and
-`JSON.stringify()` them.
-
-**For shadow DOM traversal with dynamic selectors**, write the full JS path:
-```js
-const s = document.getElementById('interop-outlet').shadowRoot;
-const el = s.querySelector('.msg-convo-wrapper');
-return JSON.stringify(el.getBoundingClientRect());
-```
-
-## Login & Auth Walls
-- If you see a "Log in" or "Sign up" prompt instead of expected
-  content, report the auth wall immediately — do NOT attempt to log in.
-- Check for cookie consent banners and dismiss them if they block content.
-
-## Efficiency
-- Minimize tool calls — combine actions where possible.
-- When a snapshot result is saved to a spillover file, use
-  `run_command` with grep to extract specific data rather than
-  re-reading the full file.
-- Call `set_output` in the same turn as your last browser action
-  when possible — don't waste a turn.
+Use for reading state inside a shadow root that standard tools don't
+handle, for one-shot site-specific actions, or to measure layout the
+tools don't expose. Do NOT use it on a strict-CSP site (LinkedIn,
+some X surfaces) with `innerHTML` — Trusted Types silently drops the
+assignment. Always use `createElement` + `appendChild` + `setAttribute`
+for DOM injection on those sites. `style.cssText`, `textContent`, and
+`.value` assignments are fine.
