-# Piker Git Commit Message Generator
-
-Generate a commit message from the staged diff above
-following the piker project's conventions (learned from
-analyzing 500 repo commits).
-
-If `$ARGUMENTS` is provided, use it as scope or
-description context for the commit message.
-
-For the full style guide with verb frequencies,
-section markers, abbreviations, piker-specific terms,
-and examples, see
-[style-guide-reference.md](./style-guide-reference.md).
-
-## Quick Reference
-
-- **Subject**: ~50 chars, present tense verb, use
-  backticks for code refs
-- **Body**: only for complex/multi-file changes,
-  67 char line max
-- **Section markers**: Also, / Deats, / Other,
-- **Bullets**: use `-` style
-- **Tone**: technical but casual (piker style)

-```
-
-## Output Instructions
-
-When generating a commit message:
-
-1. Analyze the staged diff (injected above via
-   dynamic context) to understand all changes.
-2. If `$ARGUMENTS` provides a scope (e.g.,
-   `.ib.feed`) or description, incorporate it into
-   the subject line.
-3. Write the subject line following verb + backtick
-   conventions from the
-   [style guide](./style-guide-reference.md).
-4. Add body only for multi-file or complex changes.
-5. Write the message to a file in the repo's
-   `.claude/` subdir with filename format:
-   `<timestamp>_<first-7-chars-of-last-commit-hash>_commit_msg.md`
-   where `<timestamp>` is from `date --iso-8601=seconds`.
-   Also write a copy to
-   `.claude/git_commit_msg_LATEST.md`
-   (overwrite if exists).

-# Piker Git Commit Message Style Guide
-
-Learned from analyzing 500 commits from the piker repository.
-
-## Subject Line Rules
-
-### Length
-- Target: ~50 characters (avg: 50.5 chars)
-- Maximum: 67 chars (hard limit, though historical max: 146)
-- Keep concise and descriptive
-
-### Structure
-- Use present tense verbs (Add, Drop, Fix, Move, etc.)
-- 65.6% of commits use backticks for code references
-- 33.0% use colon notation (`module.file:` prefix or `: ` separator)
-
-### Opening Verbs (by frequency)
-Primary verbs to use:
-- **Add** (8.4%) - New features, files, functionality
-- **Drop** (3.2%) - Remove features, dependencies, code
-- **Fix** (2.2%) - Bug fixes, corrections
-- **Use** (2.2%) - Switch to different approach/tool
-- **Port** (2.0%) - Migrate code, adapt from elsewhere
-- **Move** (2.0%) - Relocate code, refactor structure
-- **Always** (1.8%) - Enforce consistent behavior
-- **Factor** (1.6%) - Refactoring, code organization
-- **Bump** (1.6%) - Version/dependency updates
-- **Update** (1.4%) - Modify existing functionality
-- **Adjust** (1.0%) - Fine-tune, tweak behavior
-- **Change** (1.0%) - Modify behavior or structure
-
-Casual/informal verbs (used occasionally):
-- **Woops,** (1.4%) - Fixing mistakes
-- **Lul,** (0.6%) - Humorous corrections
-
-### Code References
-Use backticks heavily for:
-- **Module/package names**: `tractor`, `pikerd`, `polars`, `ruff`
-- **Data types**: `dict`, `float`, `str`, `None`
-- **Classes**: `MktPair`, `Asset`, `Position`, `Account`, `Flume`
-- **Functions**: `dedupe()`, `push()`, `get_client()`, `norm_trade()`
-- **File paths**: `.tsp`, `.fqme`, `brokers.toml`, `conf.toml`
-- **CLI flags**: `--pdb`
-- **Error types**: `NoData`
-- **Tools**: `uv`, `uv sync`, `httpx`, `numpy`
-
-### Colon Usage Patterns
-1. **Module prefix**: `.ib.feed: trim bars frame to start_dt`
-2. **Separator**: `Add support: new feature description`
-
-### Tone
-- Technical but casual (use XD, lol, .., Woops, Lul when appropriate)
-- Direct and concise
-- Question marks rare (1.4%)
-- Exclamation marks rare (1.4%)
-
-## Body Structure
-
-### Body Frequency
-- 56.0% of commits have empty bodies (one-line commits are common)
-- Use body for complex changes requiring explanation
-
-### Bullet Lists
-- Prefer `-` bullets (16.2% of commits)
-- Rarely use `*` bullets (1.6%)
-- Indent continuation lines appropriately
-
-### Section Markers (in order of frequency)
-Use these to organize complex commit bodies:
-
-1. **Also,** (most common, 26 occurrences)
-   - Additional changes, side effects, related updates
-   - Example:
-     ```
-     Main change described in subject.
-
-     Also,
-     - related change 1
-     - related change 2
-     ```
-
-2. **Deats,** (8 occurrences)
-   - Implementation details
-   - Technical specifics
-
-3. **Further,** (4 occurrences)
-   - Additional context or future considerations
-
-4. **Other,** (3 occurrences)
-   - Miscellaneous related changes
-
-5. **Notes,** **TODO,** (rare, 1 each)
-   - Special annotations when needed
-
-### Line Length
-- Body lines: 67 character maximum
-- Break longer lines appropriately
-
-## Language Patterns
-
-### Common Abbreviations (by frequency)
-Use these freely in commit bodies:
-- **msg** (29) - message
-- **mod** (15) - module
-- **vs** (14) - versus
-- **impl** (12) - implementation
-- **deps** (11) - dependencies
-- **var** (6) - variable
-- **ctx** (6) - context
-- **bc** (5) - because
-- **obvi** (4) - obviously
-- **ep** (4) - endpoint
-- **tn** (4) - task name
-- **rn** (3) - right now
-- **sig** (3) - signal/signature
-- **env** (3) - environment
-- **tho** (3) - though
-- **fn** (2) - function
-- **iface** (2) - interface
-- **prolly** (2) - probably
-
-Less common but acceptable:
-- **dne**, **osenv**, **gonna**, **wtf**
-
-### Tone Indicators
-- **..** (77 occurrences) - Ellipsis for trailing thoughts
-- **XD** (17) - Expression of humor/irony
-- **lol** (1) - Rare, use sparingly
-
-### Informal Patterns
-- Casual contractions okay: Don't, won't
-- Lowercase starts acceptable for file prefixes
-- Direct, conversational tone
-
-## Special Patterns
-
-### Module/File Prefixes
-Common in piker commits (33.0% use colons):
-- `.ib.feed: description`
-- `.ui._remote_ctl: description`
-- `.data.tsp: description`
-- `.accounting: description`
-
-### Merge Commits
-- 4.4% of commits (standard git merges)
-- Not a primary pattern to emulate
-
-### External References
-- GitHub links occasionally used (13 total)
-- File:line references not used (0 occurrences)
-- No WIP commits in analyzed set

-  Piker's `Profiler` API for measuring performance
-  across distributed actor systems. Apply when
-  adding profiling, debugging perf regressions, or
-  optimizing hot paths in piker code.
-user-invocable: false
----
-
-# Piker Profiling Subsystem
-
-Skill for using `piker.toolz.profile.Profiler` to
-measure performance across distributed actor systems.
-
-## Core Profiler API
-
-### Basic Usage
-
-```python
-from piker.toolz.profile import (
-    Profiler,
-    pg_profile_enabled,
-    ms_slower_then,
-)
-
-profiler = Profiler(
-    msg='<description of profiled section>',
-    disabled=False,  # IMPORTANT: enable explicitly!
-    ms_threshold=0.0,  # show all timings
-)
-
-# do work
-some_operation()
-profiler('step 1 complete')
-
-# more work
-another_operation()
-profiler('step 2 complete')
-
-# prints on exit:
-# > Entering <description of profiled section>
-#   step 1 complete: 12.34, tot:12.34
-#   step 2 complete: 56.78, tot:69.12
-# < Exiting <description>, total: 69.12 ms
-```
-
-### Default Behavior Gotcha
-
-**CRITICAL:** Profiler is disabled by default in
-many contexts!
-
-```python
-# BAD: might not print anything!
-profiler = Profiler(msg='my operation')
-
-# GOOD: explicit enable
-profiler = Profiler(
-    msg='my operation',
-    disabled=False,  # force enable!
-    ms_threshold=0.0,  # show all steps
-)
-```
-
-### Profiler Output Format
-
-```
-> Entering <msg>
-  <label 1>: <delta_ms>, tot:<cumulative_ms>
-  <label 2>: <delta_ms>, tot:<cumulative_ms>
-  ...
-< Exiting <msg>, total time: <total_ms> ms
-```
-
-**Reading the output:**
-- `delta_ms` = time since previous checkpoint
-- `cumulative_ms` = time since profiler creation
-- Final total = end-to-end time
-
-## Profiling Distributed Systems
-
-Piker runs across multiple processes (actors). Each
-actor has its own log output.
-
-### Common piker actors
-- `pikerd` - main daemon process
-- `brokerd` - broker connection actor
-- `chart` - UI/graphics actor
-- Client scripts - analysis/annotation clients
-
-### Cross-Actor Profiling Strategy
-
-1. Add `Profiler` on **both** client and server
-2. Correlate timestamps from each actor's output
-3. Calculate IPC overhead = total - (client + server
-   processing)
-
-**Example correlation:**
-
-Client console:
-```
-> Entering markup_gaps() for 1285 gaps
-  initial redraw: 0.20ms, tot:0.20
-  built annotation specs: 256.48ms, tot:256.68
-  batch IPC call complete: 119.26ms, tot:375.94
-  final redraw: 0.07ms, tot:376.02
-< Exiting markup_gaps(), total: 376.04ms
-```
-
-Server console (chart actor):
-```
-> Entering Batch annotate 1285 gaps
-  `np.searchsorted()` complete!: 0.81ms, tot:0.81
-  `time_to_row` creation: 98.45ms, tot:99.28
-  created GapAnnotations item: 2.98ms, tot:102.26
-< Exiting Batch annotate, total: 104.15ms
-```
-
-**Analysis:**
-- Total client time: 376ms
-- Server processing: 104ms
-- IPC overhead + client spec building: 272ms
-- Bottleneck: client-side spec building (256ms)
-
-## Integration with PyQtGraph
-
-Some piker modules integrate with `pyqtgraph`'s
-profiling:
-
-```python
-from piker.toolz.profile import (
-    Profiler,
-    pg_profile_enabled,
-    ms_slower_then,
-)
-
-profiler = Profiler(
-    msg='Curve.paint()',
-    disabled=not pg_profile_enabled(),
-    ms_threshold=ms_slower_then,
-)
-```
-
-## Performance Expectations
-
-**Typical timings:**
-- IPC round-trip (local actors): 1-10ms
-- NumPy binary search (10k array): <1ms
-- Dict building (1k items, simple): 1-5ms
-- Qt redraw trigger: 0.1-1ms
-- Scene item removal (100s items): 10-50ms
-
-**Red flags:**
-- Linear array scan per item: 50-100ms+ for 1k
-- Dict comprehension with struct array: 50-100ms
-- Individual Qt item creation: 5ms per item

-# Profiling Patterns
-
-Detailed profiling patterns for use with
-`piker.toolz.profile.Profiler`.
-
-## Pattern: Function Entry/Exit
-
-```python
-async def my_function():
-    profiler = Profiler(
-        msg='my_function()',
-        disabled=False,
-        ms_threshold=0.0,
-    )
-
-    step1()
-    profiler('step1')
-
-    step2()
-    profiler('step2')
-
-    # auto-prints on exit
-```
-
-## Pattern: Loop Iterations
-
-```python
-# DON'T profile inside tight loops (overhead!)
-for i in range(1000):
-    profiler(f'iteration {i}')  # NO!
-
-# DO profile around loops
-profiler = Profiler(msg='processing 1000 items')
-for i in range(1000):
-    process(item[i])
-profiler('processed all items')
-```
-
-## Pattern: Conditional Profiling
-
-```python
-# only profile when investigating specific issue
-DEBUG_REPOSITION = True
-
-def reposition(self, array):
-    if DEBUG_REPOSITION:
-        profiler = Profiler(
-            msg='GapAnnotations.reposition()',
-            disabled=False,
-        )
-
-    # ... do work
-
-    if DEBUG_REPOSITION:
-        profiler('completed reposition')
-```
-
-## Pattern: Teardown/Cleanup Profiling
-
-```python
-try:
-    # ... main work
-    pass
-finally:
-    profiler = Profiler(
-        msg='Annotation teardown',
-        disabled=False,
-        ms_threshold=0.0,
-    )
-
-    cleanup_resources()
-    profiler('resources cleaned')
-
-    close_connections()
-    profiler('connections closed')
-```
-
-## Pattern: Distributed IPC Profiling
-
-### Server-side (chart actor)
-
-```python
-# piker/ui/_remote_ctl.py
-@tractor.context
-async def remote_annotate(ctx):
-    async with ctx.open_stream() as stream:
-        async for msg in stream:
-            profiler = Profiler(
-                msg=f'Batch annotate {n} gaps',
-                disabled=False,
-                ms_threshold=0.0,
-            )
-
-            result = await handle_request(msg)
-            profiler('request handled')
-
-            await stream.send(result)
-            profiler('result sent')
-```
-
-### Client-side (analysis script)
-
-```python
-# piker/tsp/_annotate.py
-async def markup_gaps(...):
-    profiler = Profiler(
-        msg=f'markup_gaps() for {n} gaps',
-        disabled=False,
-        ms_threshold=0.0,
-    )
-
-    await actl.redraw()
-    profiler('initial redraw')
-
-    specs = build_specs(gaps)
-    profiler('built annotation specs')
-
-    # IPC round-trip!
-    result = await actl.add_batch(specs)
-    profiler('batch IPC call complete')
-
-    await actl.redraw()
-    profiler('final redraw')
-```
-
-## Common Use Cases
-
-### IPC Request/Response Timing
-
-```python
-# Client side
-profiler = Profiler(msg='Remote request')
-result = await remote_call()
-profiler('got response')
-
-# Server side (in handler)
-profiler = Profiler(msg='Handle request')
-process_request()
-profiler('request processed')
-```
-
-### Batch Operation Optimization
-
-```python
-profiler = Profiler(msg='Batch processing')
-
-items = collect_all()
-profiler(f'collected {len(items)} items')
-
-results = numpy_batch_op(items)
-profiler('numpy op complete')
-
-output = {
-    k: v for k, v in zip(keys, results)
-}
-profiler('dict built')
-```
-
-### Startup/Initialization Timing
-
-```python
-async def __aenter__(self):
-    profiler = Profiler(msg='Service startup')
-
-    await connect_to_broker()
-    profiler('broker connected')
-
-    await load_config()
-    profiler('config loaded')
-
-    await start_feeds()
-    profiler('feeds started')
-
-    return self
-```
-
-## Debugging Performance Regressions
-
-When profiler shows unexpected slowness:
-
-### 1. Add finer-grained checkpoints
-
-```python
-# was:
-result = big_function()
-profiler('big_function done')
-
-# now:
-profiler = Profiler(
-    msg='big_function internals',
-)
-step1 = part_a()
-profiler('part_a')
-step2 = part_b()
-profiler('part_b')
-step3 = part_c()
-profiler('part_c')
-```
-
-### 2. Check for hidden iterations
-
-```python
-# looks simple but might be slow!
-result = array[array['time'] == timestamp]
-profiler('array lookup')
-
-# reveals O(n) scan per call
-for ts in timestamps:  # outer loop
-    row = array[array['time'] == ts]  # O(n)!
-```
-
-### 3. Isolate IPC from computation
-
-```python
-# was: can't tell where time is spent
-result = await remote_call(data)
-profiler('remote call done')
-
-# now: separate phases
-payload = prepare_payload(data)
-profiler('payload prepared')
-
-result = await remote_call(payload)
-profiler('IPC complete')
-
-parsed = parse_result(result)
-profiler('result parsed')
-```

-  Piker developer communication style, slang, and
-  ethos. Apply when communicating with piker devs,
-  writing commit messages, code review comments, or
-  any collaborative interaction.
-user-invocable: false
----
-
-# Piker Slang & Communication Style
-
-The essential skill for fitting in with the degen
-trader-hacker class of devs who built and maintain
-`piker`.
-
-## Core Philosophy
-
-Piker devs are:
-- **Technical AF** - deep systems knowledge,
-  performance obsessed
-- **Irreverent** - don't take ourselves too
-  seriously
-- **Direct** - no corporate speak, no BS, just
-  real talk
-- **Collaborative** - we build together, debug
-  together, win together
-
-Communication style: precision meets chaos,
-academia meets /r/wallstreetbets, systems
-programming meets trading floor banter.
-
-## Grammar & Style Rules
-
-### 1. Typos with inline corrections
-```
-dint (didn't) help at all
-gonna (going to) try with...
-deats (details) wise i want...
-```
-Pattern: `[typo] ([correction])` in same sentence
-
-### 2. Casual grammar violations (embrace them!)
-- `ain't` - use freely
-- `y'all` - for addressing group
-- Starting sentences with lowercase
-- Dropping articles: "need to fix the thing"
-  becomes "need to fix thing"
-- Stream of consciousness without full sentence
-  structure
-
-### 3. Ellipsis usage
-```
-yeah i think we should try..
-..might need to also check for..
-not sure tho..
-```
-Use `..` (two dots) not `...` (three) - chiller
-
-### 4. Emphasis through spelling
-- `soooo` - very (sooo good, sooo fast)
-- `veeery` - very (veeery interesting)
-- `wayyy` - way (wayyy better)
-
-### 5. Punctuation style
-- Minimal capitalization (lowercase preferred)
-- Question marks optional if context is clear
-- Commas used sparingly
-- Lots of newlines for readability
-
-## The Degen Trader-Hacker Ethos
-
-**What we value:**

-# Piker Communication Examples
-
-Real-world interaction patterns for communicating
-in the piker dev style.
-
-## When Giving Feedback
-
-**Direct, no sugar-coating:**
-```
-BAD:  "This approach might not be optimal"
-GOOD: "this is sloppy, there's likely a better
-       vectorized approach"
-
-BAD:  "Perhaps we should consider..."
-GOOD: "you should definitely try X instead"
-
-BAD:  "I'm not entirely certain, but..."
-GOOD: "prolly it's bc we're doing Y, check the
-       profiler #s"
-```
-
-**Celebrate wins:**
-```
-"eyyooo, way faster now!"
-"booyakashaa, sub-ms lookups B)"
-"yeah definitely crushed that bottleneck"
-```
-
-**Acknowledge mistakes:**
-```
-"ahh yeah you're right, ma bad"
-"woops, forgot to check that case"
-"lul, totally missed the obvi issue there"
-```
-
-## When Explaining Technical Concepts
-
-**Mix precision with casual:**
-```
-"so basically `np.searchsorted()` is doing binary
-search which is O(log n) instead of the linear
-O(n) scan we were doing before with `np.isin()`,
-that's why it's like 1000x faster ya know?"
-```
-
-**Use backticks heavily:**
-- Wrap all code symbols: `function()`,
-  `ClassName`, `field_name`
-- File paths: `piker/ui/_remote_ctl.py`
-- Commands: `git status`, `piker store ldshm`
-
-**Explain like you're pair programming:**
-```
-"ok so the issue is prolly in `.reposition()` bc
-we're calling it with the wrong timeframe's
-array.. check line 589 where we're doing the
-timestamp lookup - that's gonna fail if the array
-has different sample times rn"
-```
-
-## When Debugging
-
-**Think out loud:**
-```
-"hmm yeah that makes sense bc..
-wait no actually..
-ahh ok i see it now, the timestamp lookups are
-failing bc.."
-```
-
-**Profile-first mentality:**
-```
-"let's add profiling around that section and see
-where the holdup is.. i'm guessing it's the dict
-building but could be the searchsorted too"
-```
-
-**Iterative refinement:**
-```
-"ok try this and lemme know the #s..
-if it's still slow we can try Y instead..
-prolly there's one more optimization left"
-```
-
-## Code Review Style
-
-**Be direct but helpful:**
-```
-"you friggin guy XD can't we just pass that to
-the meth (method) directly instead of coupling
-it to state? would be way cleaner"
-
-"cmon mann, this is python - if you're gonna use
-try/finally you need to indent all the code up
-to the finally block"
-
-"yeah looks good but prolly we should add the
-check at line 582 before we do the lookup,
-otherwise it'll spam warnings"
-```
-
-## Asking for Clarification
-
-```
-"wait so are we trying to optimize the client
-side or server side rn? or both lol"
-
-"mm yeah, any chance you can point me to the
-current code for this so i can think about it
-before we try X?"
-```
-
-## Proposing Solutions
-
-```
-"ok so i think the move here is to vectorize the
-timestamp lookups using binary search.. should
-drop that 100ms way down. wanna give it a shot?"
-
-"prolly we should just add a timeframe check at
-the top of `.reposition()` and bail early if it
-doesn't match ya?"
-```
-
-## Reacting to User Feedback
-
-```
-User: "yeah the arrows are too big now"
-Response: "ahh yeah you're right, lemme check the
-upstream `makeArrowPath()` code to see what the
-dims actually mean.."
-
-User: "dint (didn't) help at all it seems"
-Response: "bleh! ok so there's prolly another
-bottleneck then, let's add moar profiler calls
-and narrow it down"
-```
-
-## End of Session
-
-```
-"aight so we got some solid wins today:
-- ~36x client speedup (6.6s -> 376ms)
-- ~180x server speedup
-- fixed the timeframe mismatch spam
-- added teardown profiling
-
-ready to call it a night?"
-```
-
-## Advanced Moves
-
-### The Parenthetical Correction
-```
-"yeah i dint (didn't) realize we were hitting
-that path"
-"need to check the deats (details) on how
-searchsorted works"
-```
-
-### The Rhetorical Question Flow
-```
-"so like, why are we even building this dict per
-reposition call? can't we just cache it and
-invalidate when the array changes? prolly way
-faster that way no?"
-```
-
-### The Rambling Realization
-```
-"ok so the thing is.. wait actually.. hmm.. yeah
-ok so i think what's happening is the timestamp
-lookups are failing bc the 1s gaps are being
-repositioned with the 60s array.. which like,
-obvi won't have those exact timestamps bc it's
-sampled differently.. so we prolly just need to
-skip reposition if the timeframes don't match
-ya?"
-```
-
-### The Self-Deprecating Pivot
-```
-"lol ok yeah that was totally wrong, ma bad.
-let's try Y instead and see if that helps"
-```
-
-## The Vibe
-
-```
-"yo so i was profiling that batch rendering thing
-and holy shit we were doing like 3855 linear
-scans.. switched to searchsorted and boom,
-100ms -> 5ms. still think there's moar juice to
-squeeze tho, prolly in the dict building part.
-gonna add some profiler calls and see where the
-holdup is rn.
-
-anyway yeah, good sesh today B) learned a ton
-aboot pyqtgraph internals, might write that up
-as a skill file for future collabs ya know?"

----
-
-# PyQtGraph Rendering Optimization
-
-Skill for researching and optimizing `pyqtgraph`
-graphics primitives by leveraging `piker`'s
-existing extensions and production-ready patterns.
-
-## Research Flow
-
-When tasked with optimizing rendering performance
-(particularly for large datasets), follow this
-systematic approach:
-
-### 1. Study Piker's Existing Primitives
-
-Start by examining `piker.ui._curve` and related
-modules:
-
-```python
-# Key modules to review:
-piker/ui/_curve.py      # FlowGraphic, Curve
-piker/ui/_editors.py    # ArrowEditor, SelectRect
-piker/ui/_annotate.py   # Custom batch renderers
-```
-
-**Look for:**
-- Use of `QPainterPath` for batch path rendering
-- `QGraphicsItem` subclasses with custom `.paint()`
-- Cache mode settings (`.setCacheMode()`)
-- Coordinate system transformations
-- Custom bounding rect calculations
-
-### 2. Identify Upstream PyQtGraph Patterns
-
-**Key upstream modules:**
-```python
-pyqtgraph/graphicsItems/BarGraphItem.py
-    # PrimitiveArray for batch rect rendering
-
-pyqtgraph/graphicsItems/ScatterPlotItem.py
-    # Fragment-based rendering for point clouds
-
-pyqtgraph/functions.py
-    # Utility fns like makeArrowPath()
-
-pyqtgraph/Qt/internals.py
-    # PrimitiveArray for batch drawing primitives
-```
-
-**Search for:**
-- `PrimitiveArray` usage (batch rect/point)
-- `QPainterPath` batching patterns
-- Shared pen/brush reuse across items
-- Coordinate transformation strategies
-
-### 3. Core Batch Patterns
-
-**Core optimization principle:**
-Creating individual `QGraphicsItem` instances is
-expensive. Batch rendering eliminates per-item
-overhead.
-
-#### Pattern: Batch Rectangle Rendering
-
-```python
-import pyqtgraph as pg
-from pyqtgraph.Qt import QtCore
-
-class BatchRectRenderer(pg.GraphicsObject):
-    def __init__(self, n_items):
-        super().__init__()
-
-        # allocate rect array once
-        self._rectarray = (
-            pg.Qt.internals.PrimitiveArray(
-                QtCore.QRectF, 4,
-            )
-        )
-
-        # shared pen/brush (not per-item!)
-        self._pen = pg.mkPen(
-            'dad_blue', width=1,
-        )
-        self._brush = (
-            pg.functions.mkBrush('dad_blue')
-        )
-
-    def paint(self, p, opt, w):
-        # batch draw all rects in single call
-        p.setPen(self._pen)
-        p.setBrush(self._brush)
-        drawargs = self._rectarray.drawargs()
-        p.drawRects(*drawargs)  # all at once!
-```
-
-#### Pattern: Batch Path Rendering
-
-```python
-class BatchPathRenderer(pg.GraphicsObject):
-    def __init__(self):
-        super().__init__()
-        self._path = QtGui.QPainterPath()
-
-    def paint(self, p, opt, w):
-        # single path draw for all geometry
-        p.setPen(self._pen)
-        p.setBrush(self._brush)
-        p.drawPath(self._path)
-```
-
-### 4. Handle Coordinate Systems Carefully
-
-**Scene vs Data vs Pixel coordinates:**
-
-```python
-def paint(self, p, opt, w):
-    # save original transform (data -> scene)
-    orig_tr = p.transform()
-
-    # draw rects in data coordinates
-    p.setPen(self._rect_pen)
-    p.drawRects(*self._rectarray.drawargs())
-
-    # reset to scene coords for pixel-perfect
-    p.resetTransform()
-
-    # build arrow path in scene/pixel coords
-    for spec in self._specs:
-        scene_pt = orig_tr.map(
-            QPointF(x_data, y_data),
-        )
-        sx, sy = scene_pt.x(), scene_pt.y()
-
-        # arrow geometry in pixels (zoom-safe!)
-        arrow_poly = QtGui.QPolygonF([
-            QPointF(sx, sy),         # tip
-            QPointF(sx - 2, sy - 10),  # left
-            QPointF(sx + 2, sy - 10),  # right
-        ])
-        arrow_path.addPolygon(arrow_poly)
-
-    p.drawPath(arrow_path)
-
-    # restore data coordinate system
-    p.setTransform(orig_tr)
-```
-
-### 5. Minimize Redundant State
-
-**Share resources across all items:**
-```python
-# GOOD: one pen/brush for all items
-self._shared_pen = pg.mkPen(color, width=1)
-self._shared_brush = (
-    pg.functions.mkBrush(color)
-)
-
-# BAD: creating per-item (memory + time waste!)
-for item in items:
-    item.setPen(pg.mkPen(color, width=1))  # NO!
-```
-
-## Common Pitfalls
-
-1. **Don't mix coordinate systems within single
-   paint call** - decide per-primitive: data coords
-   or scene coords. Use `p.transform()` /
-   `p.resetTransform()` carefully.
-
-2. **Don't forget bounding rect updates** -
-   override `.boundingRect()` to include all
-   primitives. Update when geometry changes via
-   `.prepareGeometryChange()`.
-
-3. **Don't use ItemCoordinateCache for dynamic
-   content** - use `DeviceCoordinateCache` for
-   frequently updated items or `NoCache` during
-   interactive operations.
-
-4. **Don't trigger updates per-item in loops** -
-   batch all changes, then single `.update()`.
-
-## Performance Expectations
-
-**Individual items (baseline):**
-- 1000+ items: ~5+ seconds to create
-- Each item: ~5ms overhead (Qt object creation)
-
-**Batch rendering (optimized):**
-- 1000+ items: <100ms to create
-- Single item: ~0.01ms per primitive in batch
-- **Expected: 50-100x speedup**

-# PyQtGraph Optimization Examples
-
-Real-world optimization case studies from piker.
-
-## Case Study: Gap Annotations (1285 gaps)
-
-### Before: Individual `pg.ArrowItem` + `SelectRect`
-
-```
-Total creation time: 6.6 seconds
-Per-item overhead: ~5ms
-Memory: 1285 ArrowItem + 1285 SelectRect objects
-```
-
-Each gap was rendered as two separate
-`QGraphicsItem` instances (arrow + highlight rect),
-resulting in 2570 Qt objects.
-
-### After: Single `GapAnnotations` batch renderer
-
-```
-Total creation time:
-  104ms (server) + 376ms (client)
-Effective per-item: ~0.08ms
-Speedup: ~36x client, ~180x server
-Memory: 1 GapAnnotations object
-```
-
-All 1285 gaps rendered via:
-- One `PrimitiveArray` for all rectangles
-- One `QPainterPath` for all arrows
-- Shared pen/brush across all items
-
-### Profiler Output (Client)
-
-```
-> Entering markup_gaps() for 1285 gaps
-  initial redraw: 0.20ms, tot:0.20
-  built annotation specs: 256.48ms, tot:256.68
-  batch IPC call complete: 119.26ms, tot:375.94
-  final redraw: 0.07ms, tot:376.02
-< Exiting markup_gaps(), total: 376.04ms
-```
-
-### Profiler Output (Server)
-
-```
-> Entering Batch annotate 1285 gaps
-  `np.searchsorted()` complete!: 0.81ms, tot:0.81
-  `time_to_row` creation: 98.45ms, tot:99.28
-  created GapAnnotations item: 2.98ms, tot:102.26
-< Exiting Batch annotate, total: 104.15ms
-```
-
-## Positioning/Update Pattern
-
-For annotations that need repositioning when the
-view scrolls or zooms:
-
-```python
-def reposition(self, array):
-    '''
-    Update positions based on new array data.
-
-    '''
-    # vectorized timestamp lookups (not linear!)
-    time_to_row = self._build_lookup(array)
-
-    # update rect array in-place
-    rect_memory = self._rectarray.ndarray()
-    for i, spec in enumerate(self._specs):
-        row = time_to_row.get(spec['time'])
-        if row:
-            rect_memory[i, 0] = row['index']
-            rect_memory[i, 1] = row['close']
-            # ... width, height
-
-    # trigger repaint (single call, not per-item)
-    self.update()
-```
-
-**Key insight:** Update the underlying memory
-arrays directly, then call `.update()` once.
-Never create/destroy Qt objects during reposition.

-# Timeseries Optimization: NumPy & Polars
-
-Skill for high-performance timeseries processing
-using NumPy and Polars, with focus on patterns
-common in financial/trading applications.
-
-## Core Principle: Vectorization Over Iteration
-
-**Never write Python loops over large arrays.**
-Always look for vectorized alternatives.
-
-```python
-# BAD: Python loop (slow!)
-results = []
-for i in range(len(array)):
-    if array['time'][i] == target_time:
-        results.append(array[i])
-
-# GOOD: vectorized boolean indexing (fast!)
-results = array[array['time'] == target_time]
-```
-
-## Timestamp Lookup Patterns
-
-The most critical optimization in piker timeseries
-code. Choose the right lookup strategy:
-
-### Linear Scan (O(n)) - Avoid!
-
-```python
-# BAD: O(n) scan through entire array
-for target_ts in timestamps:  # m iterations
-    matches = array[array['time'] == target_ts]
-    # Total: O(m * n) - catastrophic!
-```
-
-**Performance:**
-- 1000 lookups x 10k array = 10M comparisons
-- Timing: ~50-100ms for 1k lookups
-
-### Binary Search (O(log n)) - Good!
-
-```python
-# GOOD: O(m log n) using searchsorted
-import numpy as np
-
-time_arr = array['time']  # extract once
-ts_array = np.array(timestamps)
-
-# binary search for all timestamps at once
-indices = np.searchsorted(time_arr, ts_array)
-
-# bounds check and exact match verification
-valid_mask = (
-    (indices < len(array))
-    &
-    (time_arr[indices] == ts_array)
-)
-
-valid_indices = indices[valid_mask]
-matched_rows = array[valid_indices]
-```
-
-**Requirements for `searchsorted()`:**
-- Input array MUST be sorted (ascending)
-- Works on any sortable dtype (floats, ints)
-- Returns insertion indices (not found =
-  `len(array)`)
-
-**Performance:**
-- 1000 lookups x 10k array = ~10k comparisons
-- Timing: <1ms for 1k lookups
-- **~100-1000x faster than linear scan**
-
-### Hash Table (O(1)) - Best for Repeated Lookups!
-
-If you'll do many lookups on same array, build
-dict once:
-
-```python
-# build lookup once
-time_to_idx = {
-    float(array['time'][i]): i
-    for i in range(len(array))
-}
-
-# O(1) lookups
-for target_ts in timestamps:
-    idx = time_to_idx.get(target_ts)
-    if idx is not None:
-        row = array[idx]
-```
-
-**When to use:**
-- Many repeated lookups on same array
-- Array doesn't change between lookups
-- Can afford upfront dict building cost
-
-## Performance Checklist
-
-When optimizing timeseries operations:
-
-- [ ] Is the array sorted? (enables binary search)
-- [ ] Are you doing repeated lookups?
-  (build hash table)
-- [ ] Are struct fields accessed in loops?
-  (extract to plain arrays)
-- [ ] Are you using boolean indexing?
-  (vectorized vs loop)
-- [ ] Can operations be batched?
-  (minimize round-trips)
-- [ ] Is memory being copied unnecessarily?
-  (use views)
-- [ ] Are you using the right tool?
-  (NumPy vs Polars)
-
-## Common Bottlenecks and Fixes
-
-### Bottleneck: Timestamp Lookups
-
-```python
-# BEFORE: O(n*m) - 100ms for 1k lookups
-for ts in timestamps:
-    matches = array[array['time'] == ts]
-
-# AFTER: O(m log n) - <1ms for 1k lookups
-indices = np.searchsorted(
-    array['time'], timestamps,
-)
-```
-

-# NumPy Structured Array Patterns
-
-Detailed patterns for working with NumPy structured
-arrays in piker's financial data processing.
-
-## Piker's OHLCV Array Dtype
-
-```python
-# typical piker array dtype
-dtype = [
-    ('index', 'i8'),   # absolute sequence index
-    ('time', 'f8'),    # unix epoch timestamp
-    ('open', 'f8'),
-    ('high', 'f8'),
-    ('low', 'f8'),
-    ('close', 'f8'),
-    ('volume', 'f8'),
-]
-
-arr = np.array(
-    [(0, 1234.0, 100, 101, 99, 100.5, 1000)],
-    dtype=dtype,
-)
-
-# field access
-times = arr['time']     # returns view, not copy
-closes = arr['close']
-```
-
-## Structured Array Performance Gotchas
-
-### 1. Field access in loops is slow
-
-```python
-# BAD: repeated struct field access per iteration
-for i, row in enumerate(arr):
-    x = row['index']    # struct access!
-    y = row['close']
-    process(x, y)
-
-# GOOD: extract fields once, iterate plain arrays
-indices = arr['index']  # extract once
-closes = arr['close']
-for i in range(len(arr)):
-    x = indices[i]      # plain array indexing
-    y = closes[i]
-    process(x, y)
-```
-
-### 2. Dict comprehensions with struct arrays
-
-```python
-# SLOW: field access per row in Python loop
-time_to_row = {
-    float(row['time']): {
-        'index': float(row['index']),
-        'close': float(row['close']),
-    }
-    for row in matched_rows  # struct access!
-}
-
-# FAST: extract to plain arrays first
-times = matched_rows['time'].astype(float)
-indices = matched_rows['index'].astype(float)
-closes = matched_rows['close'].astype(float)
-
-time_to_row = {
-    t: {'index': idx, 'close': cls}
-    for t, idx, cls in zip(
-        times, indices, closes,
-    )
-}
-```
-
-## Vectorized Boolean Operations
-
-### Basic Filtering
-
-```python
-# single condition
-recent = array[array['time'] > cutoff_time]
-
-# multiple conditions with &, |
-filtered = array[
-    (array['time'] > start_time)
-    &
-    (array['time'] < end_time)
-    &
-    (array['volume'] > min_volume)
-]
-
-# IMPORTANT: parentheses required around each!
-# (operator precedence: & binds tighter than >)
-```
-
-### Fancy Indexing
-
-```python
-# boolean mask
-mask = array['close'] > array['open']  # up bars
-up_bars = array[mask]
-
-# integer indices
-indices = np.array([0, 5, 10, 15])
-selected = array[indices]
-
-# combine boolean + fancy indexing
-mask = array['volume'] > threshold
-high_vol_indices = np.where(mask)[0]
-subset = array[high_vol_indices[::2]]  # every other
-```
-
-## Common Financial Patterns
-
-### Gap Detection
-
-```python
-# assume sorted by time
-time_diffs = np.diff(array['time'])
-expected_step = 60.0  # 1-minute bars
-
-# find gaps larger than expected
-gap_mask = time_diffs > (expected_step * 1.5)
-gap_indices = np.where(gap_mask)[0]
-
-# get gap start/end times
-gap_starts = array['time'][gap_indices]
-gap_ends = array['time'][gap_indices + 1]
-```
-
-### Rolling Window Operations
-
-```python
-# simple moving average (close)
-window = 20
-sma = np.convolve(
-    array['close'],
-    np.ones(window) / window,
-    mode='valid',
-)
-
-# stride tricks for efficiency
-from numpy.lib.stride_tricks import (
-    sliding_window_view,
-)
-windows = sliding_window_view(
-    array['close'], window,
-)
-sma = windows.mean(axis=1)
-```
-
-### OHLC Resampling (NumPy)
-
-```python
-# resample 1m bars to 5m bars
-def resample_ohlc(arr, old_step, new_step):
-    n_bars = len(arr)
-    factor = int(new_step / old_step)
-
-    # truncate to multiple of factor
-    n_complete = (n_bars // factor) * factor
-    arr = arr[:n_complete]
-
-    # reshape into chunks
-    reshaped = arr.reshape(-1, factor)
-
-    # aggregate OHLC
-    opens = reshaped[:, 0]['open']
-    highs = reshaped['high'].max(axis=1)
-    lows = reshaped['low'].min(axis=1)
-    closes = reshaped[:, -1]['close']
-    volumes = reshaped['volume'].sum(axis=1)
-
-    return np.rec.fromarrays(
-        [opens, highs, lows, closes, volumes],
-        names=[
-            'open', 'high', 'low',
-            'close', 'volume',
-        ],
-    )
-```
-
-## Memory Considerations
-
-### Views vs Copies
-
-```python
-# VIEW: shares memory (fast, no copy)
-times = array['time']         # field access
-subset = array[10:20]         # slicing
-reshaped = array.reshape(-1, 2)
-
-# COPY: new memory allocation
-filtered = array[array['time'] > cutoff]
-sorted_arr = np.sort(array)
-casted = array.astype(np.float32)
-
-# force copy when needed
-explicit_copy = array.copy()
-```
-
-### In-Place Operations
-
-```python
-# modify in-place (no new allocation)
-array['close'] *= 1.01  # scale prices
-array['volume'][mask] = 0  # zero out rows
-
-# careful: compound ops may create temporaries
-array['close'] = array['close'] * 1.01  # temp!
-array['close'] *= 1.01  # true in-place
-```

-# Polars Integration Patterns
-
-Polars usage patterns for piker's timeseries
-processing, including NumPy interop.
-
-## NumPy <-> Polars Conversion
-
-```python
-import polars as pl
-
-# numpy to polars
-df = pl.from_numpy(
-    arr,
-    schema=[
-        'index', 'time', 'open', 'high',
-        'low', 'close', 'volume',
-    ],
-)
-
-# polars to numpy (via arrow)
-arr = df.to_numpy()
-
-# piker convenience
-from piker.tsp import np2pl, pl2np
-df = np2pl(arr)
-arr = pl2np(df)
-```
-
-## Polars Performance Patterns
-
-### Lazy Evaluation
-
-```python
-# build query lazily
-lazy_df = (
-    df.lazy()
-    .filter(pl.col('volume') > 1000)
-    .with_columns([
-        (
-            pl.col('close') - pl.col('open')
-        ).alias('change')
-    ])
-    .sort('time')
-)
-
-# execute once
-result = lazy_df.collect()
-```
-
-### Groupby Aggregations
-
-```python
-# resample to 5-minute bars
-resampled = df.groupby_dynamic(
-    index_column='time',
-    every='5m',
-).agg([
-    pl.col('open').first(),
-    pl.col('high').max(),
-    pl.col('low').min(),
-    pl.col('close').last(),
-    pl.col('volume').sum(),
-])
-```
-
-## When to Use Polars vs NumPy
-
-### Use Polars when:
-- Complex queries with multiple filters/joins
-- Need SQL-like operations (groupby, window fns)
-- Working with heterogeneous column types
-- Want lazy evaluation optimization
-
-### Use NumPy when:
-- Simple array operations (indexing, slicing)
-- Direct memory access needed (e.g., SHM arrays)
-- Compatibility with Qt/pyqtgraph (expects NumPy)
-- Maximum performance for numerical computation

-# AI Tooling Integrations
-
-Documentation and usage guides for AI-assisted
-development tools integrated with this repo.
-
-Each subdirectory corresponds to a specific AI tool
-or frontend and contains usage docs for the
-custom skills/prompts/workflows configured for it.
-
-Originally introduced in
-[PR #69](https://www.pikers.dev/pikers/piker/pulls/69);
-track new integration ideas and proposals in
-[issue #79](https://www.pikers.dev/pikers/piker/issues/79).
-
-## Integrations
-
-| Tool | Directory | Status |
-|------|-----------|--------|
-| [Claude Code](https://github.com/anthropics/claude-code) | [`claude-code/`](claude-code/) | active |
-
-## Adding a New Integration
-
-Create a subdirectory named after the tool (use
-lowercase + hyphens), then add:
-
-1. A `README.md` covering setup, available
-   skills/commands, and usage examples
-2. Any tool-specific config or prompt files
-
-```

-│   └── README.md
-└── <your-tool>/
-    └── README.md
-```
-
-## Conventions
-
-- Skill/command names use **hyphen-case**
-  (`commit-msg`, not `commit_msg`)
-- Each integration doc should describe **what**
-  the skill does, **how** to invoke it, and any
-  **output** artifacts it produces
-- Keep docs concise; link to the actual skill
-  source files (under `.claude/skills/`, etc.)
-  rather than duplicating content

-skills and workflows for piker development.
-
-## Skills
-
-| Skill | Invocable | Description |
-|-------|-----------|-------------|
-| [`commit-msg`](#commit-msg) | `/commit-msg` | Generate piker-style commit messages |
-| `piker-profiling` | auto | `Profiler` API patterns for perf work |
-| `piker-slang` | auto | Communication style + slang guide |
-| `pyqtgraph-optimization` | auto | Batch rendering patterns |
-| `timeseries-optimization` | auto | NumPy/Polars perf patterns |
-
-Skills marked **auto** are background knowledge
-applied automatically when Claude detects relevance.
-Only `commit-msg` is user-invoked via slash command.
-
-Skill source files live under
-`.claude/skills/<skill-name>/SKILL.md`.
-
----
-
-## `/commit-msg`
-
-Generate piker-style git commit messages trained on
-500+ commits from the repo history.
-
-### Quick Start
-
-```
-# basic - analyzes staged diff automatically
-/commit-msg
-
-# with scope hint
-/commit-msg .ib.feed: fix bar trimming
-
-# with description context
-/commit-msg refactor position tracking
-```
-
-### What It Does
-
-1. **Reads staged changes** via dynamic context
-   injection (`git diff --staged --stat`)
-2. **Reads recent commits** for style reference
-   (`git log --oneline -10`)
-3. **Generates** a commit message following
-   piker conventions (verb choice, backtick refs,
-   colon prefixes, section markers, etc.)
-4. **Writes** the message to two files:
-   - `.claude/<timestamp>_<hash>_commit_msg.md`
-   - `.claude/git_commit_msg_LATEST.md`
-     (overwritten each time)
-
-### Arguments
-
-The optional argument after `/commit-msg` is
-passed as `$ARGUMENTS` and used as scope or
-description context. Examples:
-
-| Invocation | Effect |
-|------------|--------|
-| `/commit-msg` | Infer scope from diff |
-| `/commit-msg .ib.feed` | Use `.ib.feed:` prefix |
-| `/commit-msg fix the null seg crash` | Use as description hint |
-
-### Output Format
-
-**Subject line:**
-- ~50 chars target, 67 max
-- Present tense verb (Add, Drop, Fix, Factor..)
-- Backtick-wrapped code refs
-- Optional module prefix (`.ib.feed: ...`)
-
-**Body** (when needed):
-- 67 char line max
-- Section markers: `Also,`, `Deats,`, `Further,`
-- `-` bullet lists for multiple changes
-- Piker abbreviations (`msg`, `mod`, `impl`,
-  `deps`, `bc`, `obvi`, `prolly`..)
-
-**Footer** (always):

-[`claude-code`][claude-code-gh])
-[claude-code-gh]: https://github.com/anthropics/claude-code
-```
-
-### Output Files
-
-After generation, the commit message is written to:
-
-```
-.claude/
-├── <timestamp>_<hash>_commit_msg.md   # archived
-└── git_commit_msg_LATEST.md           # latest
-```
-
-Where `<timestamp>` is ISO-8601 with seconds and
-`<hash>` is the first 7 chars of the current
-`HEAD` commit.
-
-Use the latest file to feed into `git commit`:
-
-```bash
-git commit -F .claude/git_commit_msg_LATEST.md
-```
-
-Or review/edit before committing:
-
-```bash
-cat .claude/git_commit_msg_LATEST.md
-# edit if needed, then:
-git commit -F .claude/git_commit_msg_LATEST.md
-```
-
-### Examples
-
-**Simple one-liner output:**
-```
-Add `MktPair.fqme` property for symbol resolution
-```
-
-**Multi-file change output:**
-```
-Factor `.claude/skills/` into proper subdirs
-
-Deats,
-- `commit_msg/` -> `commit-msg/` w/ enhanced
-  frontmatter
-- all background skills set `user-invocable: false`
-- content split into supporting files
-
-(this patch was generated in some part by
-[`claude-code`][claude-code-gh])
-[claude-code-gh]: https://github.com/anthropics/claude-code
-```
-
-### Frontmatter Reference
-
-The skill's `SKILL.md` uses these Claude Code
-frontmatter fields:
-
-```yaml
----
-name: commit-msg
-description: >
-  Generate piker-style git commit messages...
-argument-hint: "[optional-scope-or-description]"
-disable-model-invocation: true
-allowed-tools:
-  - Bash(git *)
-  - Read
-  - Grep
-  - Glob
-  - Write
----
-```
-
-| Field | Purpose |
-|-------|---------|
-| `argument-hint` | Shows hint in autocomplete |
-| `disable-model-invocation` | Only user can trigger via `/commit-msg` |
-| `allowed-tools` | Tools the skill can use |
-
-### Dynamic Context
-
-The skill injects live data at invocation time
-via `!`backtick`` syntax in the `SKILL.md`:
-
-```markdown
-## Current staged changes
-!`git diff --staged --stat`
-
-## Recent commit style reference
-!`git log --oneline -10`
-```
-
-This means the staged diff stats and recent log
-are always fresh when the skill runs -- no stale
-context.

-Connecting to the API from `piker`

-In order to expose the container's API endpoint to the
-`brokerd/datad/ib` actor, we need to add a section to the user's
-`brokers.toml` config (note the below is similar to the repo-shipped
-template file),
-
-.. code:: toml
-
-    [ib]
-    # define the (set of) host-port socketaddrs that
-    # brokerd.ib will scan to connect to an API endpoint

-    ]
-    ports = [

-        7497,  # tws
-    ]
-
-    # When API endpoints are being scanned durin startup, the order
-    # of user-defined-account "names" (as defined below) here
-    # determines which py-client connection is given priority to be
-    # used for data-feed-requests by according to whichever client
-    # connected to an API endpoing which reported the equivalent
-    # account number for that name.
-    prefer_data_account = [

-    ]
-
-    # define "aliases" (names) for each account number
-    # such that the names can be reffed and logged throughout

-    # These keys will be the set exposed through the order-mode
-    # account-selection UI so that numbers are never shown.

-
-the broker daemon can also connect to the container's VNC server for
-added functionalies including,
-
-- viewing the API endpoint program's GUI for manual interventions,
-- workarounds for historical data throttling using hotkey hacks,
-
-Add a further section to `brokers.toml` which maps each API-ep's
-port to a table of VNC server connection info like,
-
-.. code:: toml
-
-    [ib.vnc_addrs]
-    4002 = {host = 'localhost', port = 5900, pw = 'doggy'}

+# macOS Compatibility Fixes for Piker/Tractor
+
+This guide documents macOS-specific issues encountered when running `piker` on macOS and their solutions. These fixes address platform differences between Linux and macOS in areas like socket credentials, shared memory naming, and async runtime coordination.
+
+## Table of Contents
+
+1. [Socket Credential Passing](#1-socket-credential-passing)
+2. [Shared Memory Name Length Limits](#2-shared-memory-name-length-limits)
+3. [Shared Memory Cleanup Race Conditions](#3-shared-memory-cleanup-race-conditions)
+4. [Async Runtime (Trio/AsyncIO) Coordination](#4-async-runtime-trioasyncio-coordination)
+
+---
+
+## 1. Socket Credential Passing
+
+### Problem
+
+On Linux, `tractor` uses `SO_PASSCRED` and `SO_PEERCRED` socket options for Unix domain socket credential passing. macOS doesn't support these constants, causing `AttributeError` when importing.
+
+```python
+# Linux code that fails on macOS
+from socket import SO_PASSCRED, SO_PEERCRED  # AttributeError on macOS
+```
+
+### Error Message
+
+```
+AttributeError: module 'socket' has no attribute 'SO_PASSCRED'
+```
+
+### Root Cause
+
+- **Linux**: Uses `SO_PASSCRED` (to enable credential passing) and `SO_PEERCRED` (to retrieve peer credentials)
+- **macOS**: Uses `LOCAL_PEERCRED` (value `0x0001`) instead, and doesn't require enabling credential passing
+
+### Solution
+
+Make the socket credential imports platform-conditional:
+
+**File**: `tractor/ipc/_uds.py` (or equivalent in `piker` if duplicated)
+
+```python
+import sys
+from socket import (
+    socket,
+    AF_UNIX,
+    SOCK_STREAM,
+)
+
+# Platform-specific credential passing constants
+if sys.platform == 'linux':
+    from socket import SO_PASSCRED, SO_PEERCRED
+elif sys.platform == 'darwin':  # macOS
+    # macOS uses LOCAL_PEERCRED instead of SO_PEERCRED
+    # and doesn't need SO_PASSCRED
+    LOCAL_PEERCRED = 0x0001
+    SO_PEERCRED = LOCAL_PEERCRED  # Alias for compatibility
+    SO_PASSCRED = None  # Not needed on macOS
+else:
+    # Other platforms - may need additional handling
+    SO_PASSCRED = None
+    SO_PEERCRED = None
+
+# When creating a socket
+if SO_PASSCRED is not None:
+    sock.setsockopt(SOL_SOCKET, SO_PASSCRED, 1)
+
+# When getting peer credentials
+if SO_PEERCRED is not None:
+    creds = sock.getsockopt(SOL_SOCKET, SO_PEERCRED, struct.calcsize('3i'))
+```
+
+### Implementation Notes
+
+- The `LOCAL_PEERCRED` value `0x0001` is specific to macOS (from `<sys/un.h>`)
+- macOS doesn't require explicitly enabling credential passing like Linux does
+- Consider using `ctypes` or `cffi` for a more robust solution if available
+
+---
+
+## 2. Shared Memory Name Length Limits
+
+### Problem
+
+macOS limits POSIX shared memory names to **31 characters** (defined as `PSHMNAMLEN` in `<sys/posix_shm_internal.h>`). Piker generates long descriptive names that exceed this limit, causing `OSError`.
+
+```python
+# Long name that works on Linux but fails on macOS
+shm_name = "piker_quoter_tsla.nasdaq.ib_hist_1m"  # 39 chars - too long!
+```
+
+### Error Message
+
+```
+OSError: [Errno 63] File name too long: '/piker_quoter_tsla.nasdaq.ib_hist_1m'
+```
+
+### Root Cause
+
+- **Linux**: Supports shared memory names up to 255 characters
+- **macOS**: Limits to 31 characters (including leading `/`)
+
+### Solution
+
+Implement automatic name shortening for macOS while preserving the original key for lookups:
+
+**File**: `piker/data/_sharedmem.py`
+
+```python
+import hashlib
+import sys
+
+def _shorten_key_for_macos(key: str) -> str:
+    '''
+    macOS has a 31 character limit for POSIX shared memory names.
+    Hash long keys to fit within this limit while maintaining uniqueness.
+    '''
+    # macOS shm_open() has a 31 char limit (PSHMNAMLEN)
+    # Use format: /p_<hash16> where hash is first 16 hex chars of sha256
+    # This gives us: / + p_ + 16 hex chars = 19 chars, well under limit
+    # We keep the 'p' prefix to indicate it's from piker
+    if len(key) <= 31:
+        return key
+
+    # Create a hash of the full key
+    key_hash = hashlib.sha256(key.encode()).hexdigest()[:16]
+    short_key = f'p_{key_hash}'
+    return short_key
+
+
+class _Token(Struct, frozen=True):
+    '''
+    Internal representation of a shared memory "token"
+    which can be used to key a system wide post shm entry.
+    '''

+    shm_first_index_name: str
+    shm_last_index_name: str
+    dtype_descr: tuple
+    size: int  # in struct-array index / row terms
+    key: str | None = None  # original descriptive key (for lookup)
+
+    def __eq__(self, other) -> bool:
+        '''
+        Compare tokens based on shm names and dtype, ignoring the key field.
+        The key field is only used for lookups, not for token identity.
+        '''
+        if not isinstance(other, _Token):
+            return False
+        return (
+            self.shm_name == other.shm_name
+            and self.shm_first_index_name == other.shm_first_index_name
+            and self.shm_last_index_name == other.shm_last_index_name
+            and self.dtype_descr == other.dtype_descr
+            and self.size == other.size
+        )
+
+    def __hash__(self) -> int:
+        '''Hash based on the same fields used in __eq__'''
+        return hash((
+            self.shm_name,
+            self.shm_first_index_name,
+            self.shm_last_index_name,
+            self.dtype_descr,
+            self.size,
+        ))
+
+
+def _make_token(
+    key: str,
+    size: int,
+    dtype: np.dtype | None = None,
+) -> _Token:
+    '''
+    Create a serializable token that uniquely identifies a shared memory segment.
+    '''
+    if dtype is None:
+        dtype = def_iohlcv_fields
+
+    # On macOS, shorten long keys to fit the 31-char limit
+    if sys.platform == 'darwin':
+        shm_name = _shorten_key_for_macos(key)
+        shm_first = _shorten_key_for_macos(key + "_first")
+        shm_last = _shorten_key_for_macos(key + "_last")
+    else:
+        shm_name = key
+        shm_first = key + "_first"
+        shm_last = key + "_last"
+
+    return _Token(
+        shm_name=shm_name,
+        shm_first_index_name=shm_first,
+        shm_last_index_name=shm_last,
+        dtype_descr=tuple(np.dtype(dtype).descr),
+        size=size,
+        key=key,  # Store original key for lookup
+    )
+```
+
+### Key Design Decisions
+
+1. **Hash-based shortening**: Uses SHA256 to ensure uniqueness and avoid collisions
+2. **Preserve original key**: Store the original descriptive key in the `_Token` for debugging and lookups
+3. **Custom equality**: The `__eq__` and `__hash__` methods ignore the `key` field to ensure tokens are compared by their actual shm properties
+4. **Platform detection**: Only applies shortening on macOS (`sys.platform == 'darwin'`)
+
+### Edge Cases to Consider
+
+- Token serialization across processes (the `key` field must survive IPC)
+- Token lookup in dictionaries and caches
+- Debugging output (use `key` field for human-readable names)
+
+---
+
+## 3. Shared Memory Cleanup Race Conditions
+
+### Problem
+
+During teardown, shared memory segments may be unlinked by one process while another is still trying to clean them up, causing `FileNotFoundError` to crash the application.
+
+### Error Message
+
+```
+FileNotFoundError: [Errno 2] No such file or directory: '/p_74c86c7228dd773b'
+```
+
+### Root Cause
+
+In multi-process architectures like `tractor`, multiple processes may attempt to clean up shared resources simultaneously. Race conditions during shutdown can cause:
+
+1. Process A unlinks the shared memory
+2. Process B tries to unlink the same memory → `FileNotFoundError`
+3. Uncaught exception crashes Process B
+
+### Solution
+
+Add defensive error handling to catch and log cleanup races:
+
+**File**: `piker/data/_sharedmem.py`
+
+```python
+class ShmArray:
+    # ... existing code ...
+
+    def destroy(self) -> None:
+        '''
+        Destroy the shared memory segment and cleanup OS resources.
+        '''
+        if _USE_POSIX:
+            # We manually unlink to bypass all the "resource tracker"
+            # nonsense meant for non-SC systems.
+            shm = self._shm
+            name = shm.name
+            try:
+                shm_unlink(name)
+            except FileNotFoundError:
+                # Might be a teardown race where another process
+                # already unlinked it - this is fine, just log it
+                log.warning(f'Shm for {name} already unlinked?')
+
+        # Also cleanup the index counters
+        if hasattr(self, '_first'):
+            try:
+                self._first.destroy()
+            except FileNotFoundError:
+                log.warning(f'First index shm already unlinked?')
+
+        if hasattr(self, '_last'):
+            try:
+                self._last.destroy()
+            except FileNotFoundError:
+                log.warning(f'Last index shm already unlinked?')
+
+
+class SharedInt:
+    # ... existing code ...
+
+    def destroy(self) -> None:
+        if _USE_POSIX:
+            # We manually unlink to bypass all the "resource tracker"
+            # nonsense meant for non-SC systems.
+            name = self._shm.name
+            try:
+                shm_unlink(name)
+            except FileNotFoundError:
+                # might be a teardown race here?
+                log.warning(f'Shm for {name} already unlinked?')
+```
+
+### Implementation Notes
+
+- This fix is platform-agnostic but particularly important on macOS where the shortened names make debugging harder
+- The warnings help identify cleanup races during development
+- Consider adding metrics/counters if cleanup races become frequent
+
+---
+
+## 4. Async Runtime (Trio/AsyncIO) Coordination
+
+### Problem
+
+The `TrioTaskExited` error occurs when trio tasks are cancelled while asyncio tasks are still running, indicating improper coordination between the two async runtimes.
+
+### Error Message
+
+```
+tractor._exceptions.TrioTaskExited: but the child `asyncio` task is still running?
+>>
+ |_<Task pending name='Task-2' coro=<wait_on_coro_final_result()> ...>
+```
+
+### Root Cause
+
+`tractor` uses "guest mode" to run trio as a guest in asyncio's event loop (or vice versa). The error occurs when:
+
+1. A trio task is cancelled (e.g., user closes the UI)
+2. The cancellation propagates to cleanup handlers
+3. Cleanup tries to exit while asyncio tasks are still running
+4. The `translate_aio_errors` context manager detects this inconsistent state
+
+### Current State
+
+This issue is **partially resolved** by the other fixes (socket credentials and shared memory), which eliminate the underlying errors that trigger premature cancellation. However, it may still occur in edge cases.
+
+### Potential Solutions
+
+#### Option 1: Improve Cancellation Propagation (Tractor-level)
+
+**File**: `tractor/to_asyncio.py`
+
+```python
+async def translate_aio_errors(
+    chan,
+    wait_on_aio_task: bool = False,
+    suppress_graceful_exits: bool = False,
+):
+    '''
+    Context manager to translate asyncio errors to trio equivalents.
+    '''
+    try:
+        yield
+    except trio.Cancelled:
+        # When trio is cancelled, ensure asyncio tasks are also cancelled
+        if wait_on_aio_task:
+            # Give asyncio tasks a chance to cleanup
+            await trio.lowlevel.checkpoint()
+
+            # Check if asyncio task is still running
+            if aio_task and not aio_task.done():
+                # Cancel it gracefully
+                aio_task.cancel()
+
+                # Wait briefly for cancellation
+                with trio.move_on_after(0.5):  # 500ms timeout
+                    await wait_for_aio_task_completion(aio_task)
+
+        raise  # Re-raise the cancellation
+```
+
+#### Option 2: Proper Shutdown Sequence (Application-level)
+
+**File**: `piker/brokers/ib/api.py` (or similar broker modules)
+
+```python
+async def load_clients_for_trio(
+    client: Client,
+    ...
+) -> None:
+    '''
+    Load asyncio client and keep it running for trio.
+    '''
+    try:
+        # Setup client
+        await client.connect()
+
+        # Keep alive - but make it cancellable
+        await trio.sleep_forever()
+
+    except trio.Cancelled:
+        # Explicit cleanup before propagating cancellation
+        log.info("Shutting down asyncio client gracefully")
+
+        # Disconnect client
+        if client.isConnected():
+            await client.disconnect()
+
+        # Small delay to let asyncio cleanup
+        await trio.sleep(0.1)
+
+        raise  # Now safe to propagate
+```
+
+#### Option 3: Detection and Warning (Current Approach)
+
+The current code detects the issue and raises a clear error. This is acceptable if:
+1. The error is rare (only during abnormal shutdown)
+2. It doesn't cause data loss
+3. Logs provide enough info for debugging
+
+### Recommended Approach
+
+For **piker**: Implement Option 2 (proper shutdown sequence) in broker modules where asyncio is used.
+
+For **tractor**: Consider Option 1 (improved cancellation propagation) as a library-level enhancement.
+
+### Testing
+
+Test the fix by:
+
+```python
+# Test graceful shutdown
+async def test_asyncio_trio_shutdown():
+    async with open_channel_from(...) as (first, chan):
+        # Do some work
+        await chan.send(msg)
+
+        # Trigger cancellation
+        raise KeyboardInterrupt
+
+    # Should cleanup without TrioTaskExited error
+```
+
+---
+
+## Summary of Changes
+
+### Files Modified in Piker
+
+1. **`piker/data/_sharedmem.py`**
+   - Added `_shorten_key_for_macos()` function
+   - Modified `_Token` class to store original `key`
+   - Modified `_make_token()` to use shortened names on macOS
+   - Added `FileNotFoundError` handling in `destroy()` methods
+
+2. **`piker/ui/_display.py`**
+   - Removed assertion that checked for 'hist' in shm name (incompatible with shortened names)
+
+### Files to Modify in Tractor (Recommended)
+
+1. **`tractor/ipc/_uds.py`**
+   - Make socket credential imports platform-conditional
+   - Handle macOS-specific `LOCAL_PEERCRED`
+
+2. **`tractor/to_asyncio.py`** (Optional)
+   - Improve cancellation propagation between trio and asyncio
+   - Add graceful shutdown timeout for asyncio tasks
+
+### Platform Detection Pattern
+
+Use this pattern consistently:
+
+```python
+import sys
+
+if sys.platform == 'darwin':  # macOS
+    # macOS-specific code
+    pass
+elif sys.platform == 'linux':  # Linux
+    # Linux-specific code
+    pass
+else:
+    # Other platforms / fallback
+    pass
+```
+
+### Testing Checklist
+
+- [ ] Test on macOS (Darwin)
+- [ ] Test on Linux
+- [ ] Test shared memory with names > 31 chars
+- [ ] Test multi-process cleanup race conditions
+- [ ] Test graceful shutdown (Ctrl+C)
+- [ ] Test abnormal shutdown (kill signal)
+- [ ] Verify no memory leaks (check `/dev/shm` on Linux, `ipcs -m` on macOS)
+
+---
+
+## Additional Resources
+

+
+## Contributing
+
+When implementing these fixes in your own project:
+
+1. **Test thoroughly** on both macOS and Linux
+2. **Add platform guards** to prevent cross-platform breakage
+3. **Document platform-specific behavior** in code comments
+4. **Consider CI/CD** testing on multiple platforms
+5. **Handle edge cases** gracefully with proper logging
+
+If you find additional macOS-specific issues, please contribute to this guide!

+
+### How to test it?
+
+**Before start:** in order to get this working with `uv`,  you
+**must** use my [`tractor` fork](https://pikers.dev/ntorres/tractor/src/branch/aio_abandons)
+and this branch: `aio_abandons`, the reason is that I cherry-pick the
+`uv_migration` that guille made, for some reason that a didn't dive
+into, in my system y need tractor using `uv` too. quite hacky
+I guess.
+
+1. `uv lock`
+
+2. `uv run --no-dev python examples/max_pain.py`
+
+3. A message should be display, enter one of the expiration date
+   available.
+
+4. The script should be up and running.
