+# AGENTS.md
+
+Agent handbook for the ShellSpy (Punk Shell) repository. These guidelines cover builds, linting, testing, code style, and day-to-day conventions for all contributors and agentic assistants. Always check for nested `AGENTS.md` files before editing subdirectories—this root spec applies repo-wide unless overridden deeper in the tree.
+
+## Quickstart Checklist
+- Confirm Windows-friendly Tcl toolchain (8.6+ required, 9.0 supported).
+- Run `tclsh make.tcl` once after cloning to populate generated assets.
+- Keep edits within the scoped instructions of any nested `AGENTS.md`.
+- Use `tclint` before submitting code to align formatting and structure.
+- Execute at least one relevant test script (`tclsh scriptlib/tests/<file>.tcl`).
+- Document changes impacting build, tooling, or developer workflow.
+
+## Build & Bootstrap Commands
+- **Primary build**: `tclsh make.tcl` (Windows default) or `punk make.tcl` inside Punk shell.
+- **Alt entry point**: `punk build.tcl` or `tclsh build.tcl` for kettle-style builds.
+- **Bootstrap shell**: `pmix KettleShell` from inside Punk shell for advanced packaging tasks.
+- **Clean/resync**: Remove `build/` artifacts then rerun `tclsh make.tcl`; avoid partial cleans that break boot modules.
+- **Binary images**: Use `punk make.tcl --target <name>` when producing platform-specific bundles (see script comments for targets).
+
+## Testing Strategy
+- **Test location**: `scriptlib/tests/` holds all Tcl test scripts; keep new tests there.
+- **Run entire suite**: Iterate with `for /r scriptlib\tests %f in (*.tcl) do tclsh %f` (Windows) or a similar shell loop on POSIX.
+- **Run single test**: `tclsh scriptlib/tests/<test_name>.tcl` (e.g., `tclsh scriptlib/tests/json.tcl`).
+- **Focused verification**: Mirror production pipelines inside tests using Punk pipeline syntax for parity.
+- **Test dependencies**: Every test must `package require punk`; declare extra packages explicitly to avoid hidden dependencies.
+- **Failure triage**: Capture stderr logs; prefer `try/on error` blocks inside tests for clearer diagnostics.
+
+## Linting & Formatting
+- **Command**: `tclint` (configured via `tclint.toml` in repo root).
+- **Files covered**: `.tcl`, `.tm`, `.sdc`; extend config if new extensions appear.
+- **Line length**: Hard cap at 400 characters; wrap pipelines thoughtfully instead of exceeding.
+- **Blank lines**: No more than 10 consecutive blanks.
+- **Indentation**: 4 spaces; tabs are disallowed in Tcl sources except inside string literals.
+- **Auto-fixes**: Run `tclint --fix` only when you have reviewed the resulting diff.
+
+## Toolchain & Dependencies
+- Prefer the provided vendor modules under `src/vendor*` before fetching new dependencies.
+- Use `tcl::tm::path add <dir>` to surface project modules when writing new tooling.
+- Keep compatibility with Tcl 8.6+; gate 9.0-specific features behind version checks.
+- When optional compiled extensions (e.g., `twapi`, `tdom`) are necessary, guard `package require` calls with fallback messaging.
+
+## Repository Layout Primer
+```
+src/
+  bootsupport/modules/      # Early-load modules with minimal deps
+  modules/                  # Main Punk modules (.tm)
+  lib/                      # Classic Tcl libraries
+  scriptapps/               # Entry-point scripts for Punk apps
+  vendormodules*/           # Third-party modules bundled with repo
+scriptlib/                  # Shared utilities + tests
+bin/                        # Helper binaries/scripts
+callbacks/, plugj.tcl, etc  # Integration glue for host environments
+src/vfs/*                   # Virtual file system images for builds
+```
+Treat VFS directories as generated artifacts; edit them only when updating runtime payloads.
+
+## Imports & Package Management
+- Always declare dependencies explicitly using `package require <name>` near file tops.
+- Prefer fully-qualified namespaces when referencing external packages (`package require tcl::zlib`, `package require TclOO`).
+- Organize custom modules as `namespace eval punk::<segment>` with filenames like `src/modules/punk/<segment>-<version>.tm`.
+- Use semantic versions that `package vcompare` can interpret; strip leading zeros.
+- For optional features, probe with `if {[catch {package require foo}]} { ... }` and degrade gracefully.
+
+## Formatting & Layout Rules
+- Opening braces stay on the same line for procs; multiline control structures may place braces on new lines for readability.
+- Align continuations under their opening command; use explicit `\` when mapping to pipeline syntax is unclear.
+- Keep pipelines readable by aligning `% var = ...` and `pipecase` segments vertically when possible.
+- Document non-trivial procedures and exports with the standard header template (see below).
+
+## Naming Conventions
+- **Procedures**: `lowercase_with_underscores` for internals, `camelCase` allowed for public APIs where existing patterns fit.
+- **Variables**: `lowercase_with_underscores`; avoid single-letter names except for loop indices.
+- **Namespaces**: Mirror directory structure; nested modules should reflect filesystem hierarchy.
+- **Private helpers**: Prefix with `_` (e.g., `_resolve_stream`); do not export them.
+- **Constants**: `UPPER_CASE_WITH_UNDERSCORES` declared via `namespace eval { variable CONSTANT value }` when practical.
+
+## Procedure Documentation Template
+```tcl
+# <Procedure summary>
+# Args:
+#   arg1 - description
+#   arg2 - description
+# Returns:
+#   Description of return value
+proc procedure_name {arg1 arg2} {
+    # Implementation
+}
+```
+Update the template with concrete details whenever functions are user-facing or complex.
+
+## Error Handling & Logging
+- Prefer `try { ... } on error {result options} { ... }` (Tcl 8.6+) for structured handling.
+- Fallback pattern:
+  ```tcl
+  if {[catch {some_command} result]} {
+      puts stderr "Error: $result"
+      return -code error $result
+  }
+  ```
+- For Punk pipelines, wrap risky commands inside `pipecase` blocks and emit descriptive messages via `puts stderr` or Punk logging helpers.
+- Never swallow errors silently; propagate with context so shell users see actionable details.
+
+## Pipeline & Functional Style Notes
+- Use `% var = ...` bindings to capture intermediate values; keep names meaningful.
+- `pipecase` should list specific patterns before catch-alls to avoid hidden matches.
+- `fun name pattern { ... }` definitions should remain side-effect light; treat them as pure functions unless otherwise documented.
+- Keep pipelines short and composable; extract into helper procs or `fun` definitions when they exceed ~10 logical steps.
+
+## Module Structure Expectations
+```tcl
+# Module description
+package require <dependencies>
+
+namespace eval <module_namespace> {
+    variable version <semver>
+    namespace export public_proc1 public_proc2
+
+    proc public_proc1 {args} {
+        # Implementation
+    }
+
+    proc _private_helper {} {
+        # Private implementation
+    }
+}
+```
+Ensure module filenames include the version (`punk/console-0.1.1.tm`), and keep `namespace export` lists alphabetized for clarity.
+
+## Type & Data Handling
+- Tcl is dynamically typed; emulate structural typing via argument validation at proc boundaries.
+- Validate user inputs with `switch -exact`, `regexp`, or Punk pipeline predicates before mutation.
+- Use dictionaries for structured data; avoid parallel lists.
+- When bridging to binary data (e.g., ANSI/xbin parsing), document expected encodings and conversions.
+
+## Versioning & Releases
+- Stick to semantic versioning (`major.minor.patch`).
+- When referencing ranges, use bounded specs (e.g., `1.2.3-2.0.0`).
+- Convert loose versions to bounded form in module metadata; helper utilities exist in boot modules for this purpose.
+- Update `punk::libunknown` registries whenever adding/removing modules to keep discovery accurate.
+
+## Platform & Performance Notes
+- Primary target: Windows (win32-x86_64). Validate code paths that rely on Windows-only packages.
+- Secondary targets: Linux/macOS/FreeBSD; guard platform-specific calls with `if {$tcl_platform(os) eq "Windows"} {...}`.
+- Favor compiled extensions (tcllibc, twapi) when available, but always provide scripted fallbacks.
+- Be mindful of long-running pipelines; chunk work and avoid blocking the Punk shell UI thread.
+
+## Documentation & Comments
+- Keep inline comments concise; describe intent, not mechanics.
+- Update any relevant docs or usage notes in `scriptapps` when behavior changes.
+- Mention environment variables or flags required to run new features.
+
+## Agent Workflow Tips
+- No `.cursor/rules/`, `.cursorrules`, or `.github/copilot-instructions.md` files exist as of this update. If they appear later, integrate their instructions here.
+- Always re-run `tclint` and the most specific test affected by your changes before committing.
+- When touching VFS payloads, describe regeneration steps inside commit messages and this guide if persistent.
+- Favor incremental commits tied to logical units of work; avoid monolithic diffs mixing tooling and feature changes.
+
+## Final Submission Checklist
+- [ ] Nested `AGENTS.md` files checked for scope-specific rules.
+- [ ] `tcllint` (and `tcllint --fix` if needed) executed with clean results.
+- [ ] Relevant tests (`tclsh scriptlib/tests/<file>.tcl`) executed and passing.
+- [ ] Build step (`tclsh make.tcl`) verified when touching build-critical code.
+- [ ] Documentation/comments updated for new behavior or flags.
+- [ ] Diffs reviewed to ensure no stray whitespace or debugging output remains.
+
+Adhering to these conventions keeps the ShellSpy/Punk Shell ecosystem consistent, portable, and friendly for future agentic collaborators. Happy hacking!

+
+            The entire IPv4 multicast range is 224.0.0.0 - 239.255.255.255,
+            The upper end 239.0.0.0 - 239.255.255.255 is classified by
+            IANA as 'administratively scoped' (RFC 2365).
+
+            The 239.0.0.0/8 range is 24 bits and *may* be available for VXLANs.
+            vni_to_mcast will map the VNI into an address in this /8 range.
+
+            The range 239.192.0.0/14 is defined by RFC 2365 to be the
+            'IPv4 Organization Local Scope' and it may be desirable to use
+            mappings that fall only within this range.
+
+            Some vendors put restrictions on acceptable VNI values e.g
+            Cisco supports VNI values from 4096 to 16,777,215.
+
+            2 ranges within 239.0.0.0/8 are best avoided if it is desired
+            to reduce flooding by layer 2 switches and possible additional
+            processor load at VTEPs.
+            These are:
+                239.0.0.0/24   (VNI 0 - 255)
+                and
+                239.128.0.0/24 (VNI 8388608 - 8388863)
+            These happen to map to the same MAC address range (01:00:5e:00:00:xx)
+            as multicast addresses in the Link-Local Block (224.0.0.0/24)
+            These are commonly flooded to all ports on the switch even when IGMP
+            snooping is enabled (protocols such as OSPF would break if such flooding
+            wasn't done, as IGMP Membership Reports are normally not sent for multicast
+            traffic in the Link-Local Block).

+# test module information
+---
+subfolders (that don't begin with a # or _ character) within this test folder form part of the Tcl namespace of the resulting modules that are produced from running '<tclshbinary> src/make.tcl modules'
+
+The #modpod- folder for a module contain files that will stored in the final module's .tm file (zip based) which is built by make.tcl into the <projectroot>/modules/test folder (again with further subfolders depending on whether the module is namespaced)
+
+The final version of the built modules are determined from corresponding <tailname>-buildversion.txt files placed at the same level as the corresponding #modpod-<tailname>-999999.0a1.0 folder
+
+example: A final installed module <projectroot>/modules/test/foo/baz/foobazzer-1.1.tm corresponds to the tcl module test::foo::baz::foobazzer and will have its source tests and associated files in the folder <projectroot>/src/modules/test/foo/baz/#modpod-foobazzer-999999.0a1.0 with a corresponding version number file at <projectroot>/src/modules/test/foo/baz/foobazzer-buildversion.txt
+
+A new testmodule for a package can be generated from the template template_test  built into the punk::mix::templates package which is referenced as 'punk.test' when creating a new module using the 'dev module.new' command. This command is an alias for punk::mix::commandset::module::new.

+#PATTERN
+# - A prototype-based Object system.
+#
+# Julian Noble 2003
+# License: Public domain
+#
+
+# "I need pattern"  - Lexx Series 1 Episode 3 - Eating Pattern. 
+#
+#
+# Pattern uses a mixture of class-based and prototype-based object instantiation.
+#
+# A pattern object has 'properties' and 'methods'
+# The system makes a distinction between them with regards to the access syntax for write operations, 
+# and yet provides unity in access syntax for read operations.
+# e.g  >object . myProperty
+# will return the value of the property 'myProperty'
+#      >ojbect . myMethod
+# will return the result of the method 'myMethod'
+# contrast this with the write operations:
+# set [>object . myProperty .] blah
+# >object . myMethod blah
+# however, the property can also be read using:
+# set [>object . myProperty .] 
+# Note the trailing . to give us a sort of 'reference' to the property.
+# this is NOT equivalent to 
+# set [>object . myProperty]
+# This last example is of course calling set against a standard variable whose name is whatever value is returned by reading the property
+# i.e it is equivalent in this case to: set blah
+
+#All objects are represented by a command, the name of which contains a leading ">".
+#Any commands in the interp which use this naming convention are assumed to be a pattern object.
+#Use of non-pattern commands containing this leading character is not supported. (Behaviour is undefined)
+
+#All user-added properties & methods of the wrapped object are accessed 
+# using the separator character "."
+#Metamethods supplied by the patterm system are accessed with the object command using the metamethod separator ".."
+# e.g to instantiate a new object from an existing 'pattern' (the equivalent of a class or prototype)
+# you would use the 'Create' metamethod on the pattern object like so:
+# >MyFactoryClassOrPrototypeLikeThing .. Create >NameOfNewObject
+# '>NameOfNewObject' is now available as a command, with certain inherited methods and properties
+# of the object it was created from. (
+
+
+#The use of the access-syntax separator character "." allows objects to be kept
+# 'clean' in the sense that the only methods &/or properties that can be called this way are ones
+# the programmer(you!) put there. Existing metamethods such as 'Create' are accessed using a different syntax
+# so you are free to implement your own 'Create' method on your object that doesn't conflict with
+# the metamethod.
+
+#Chainability  (or how to violate the Law of Demeter!)
+#The . access-syntax gives TCL an OO syntax more closely in line with many OO systems in other
+# languages such as Python & VB, and allows left to right keyboard-entry of a deeply nested object-reference
+# structure, without the need to regress to enter matching brackets as is required when using
+# standard TCL command syntax. 
+# ie instead of: 
+# [[[object nextObject] getItem 4] getItem [chooseItemNumber]] doSomething
+# we can use:
+# >object . nextObject . getItem 4 . getItem [chooseItemNumber] . doSomething
+#
+# This separates out the object-traversal syntax from the TCL command syntax.
+
+# . is the 'traversal operator' when it appears between items in a commandlist 
+# . is the 'reference operator' when it is the last item in a commandlist
+# , is the 'index traversal operator' (or 'nest operator') - mathematically it marks where there is a matrix 'partition'. 
+#   It marks breaks in the multidimensional structure that correspond to how the data is stored. 
+#   e.g  obj . arraydata x y , x1 y1 z1 
+#   represents an element of a 5-dimensional array structured as a plane of cubes
+#   e.g2 obj . arraydata x y z , x1 y1
+#   represents an element of a 5-dimensional array structured as a cube of planes
+#   The underlying storage for e.g2 might  consist of something such as a Tcl array indexed such as cube($x,$y,$z) where each value is a patternlib::>matrix object with indices x1 y1
+# .. is the 'meta-traversal operator' when it appears between items in a commandlist
+# .. is the 'meta-info operator'(?) when it is the last item in a commandlist

+
+#CHANGES
+#2018-09 - v 1.2.2
+# varied refactoring
+# Changed invocant datastructure curried into commands (the _ID_ structure)
+# Changed MAP structure to dict
+# Default Method no longer magic "item" - must be explicitly set with .. DefaultMethod (or  .. PatternDefaultMethod for patterns)
+# updated test suites
+#2018-08 - v 1.2.1
+# split ::p::predatorX functions into separate files (pkgs) 
+# e.g patternpredator2-1.0.tm
+# patternpredator1-1.0 - split out but not updated/tested - probably obsolete and very broken
+#
+#2017-08 - v 1.1.6 Fairly big overhaul 
+# New predator function using coroutines
+# Added bang operator !
+# Fixed Constructor chaining
+# Added a few tests to test::pattern
+#        
+#2008-03  - preserve ::errorInfo during var writes
+
+#2007-11
+#Major overhaul + new functionality + new tests v 1.1
+# new dispatch system - 'predator'.
+# (preparing for multiple interface stacks, multiple invocants etc)
+#
+#
+#2006-05
+# Adjusted 'var' expansion to use the new tcl8.5 'namespace upvar $ns v1 n1 v2 n2 ... ' feature.
+#
+#2005-12
+# Adjusted 'var' expansion in method/constructor etc bodies to be done 'inline' where it appears rather than aggregated at top.
+#
+# Fixed so that PatternVariable default applied on Create.
+#
+# unified interface/object datastructures under ::p::<id>:: instead of seperate ::p::IFACE::<id>::
+#  - heading towards multiple-interface objects
+#
+#2005-10-28
+# 1.0.8.1 passes 80/80 tests
+# >object .. Destroy - improved cleanup of interfaces & namespaces.
+#
+#2005-10-26
+# fixes to refsync  (still messy!)
+# remove variable traces on REF vars during .. Destroy
+# passes 76/76
+#
+#2005-10-24
+# fix objectRef_TraceHandler so that reading a property via an object reference using array syntax will call a PropertyRead function if defined.
+# 1.0.8.0 now passes 75/76
+#
+#2005-10-19
+# Command alias introduced by @next@ is now placed in the interfaces namespace. (was unnamespaced before)
+# changed IFACE array names for level0 methods to be m-1 instead of just m.  (now consistent with higher level m-X names)
+# 1.0.8.0 (passes 74/76)  
+#  tests now in own package
+#  usage:
+#  package require test::pattern
+#  test::p::list
+#  test::p::run ?nameglob? ?-version <value>?
+#
+#2005-09?-12
+#
+# fixed standalone 'var' statement in method bodies so that no implicit variable declarations added to proc.
+# fixed @next@ so that destination method resolved at interface compile time instead of call time 
+# fixed @next@ so that on Create, .. PatternMethod x overlays existing method produced by a previous .. PatternMethod x. 
+#  (before, the overlay only occured when '.. Method' was used to override.)
+# 
+# 
+# miscellaneous tidy-ups 
+#
+# 1.0.7.8 (passes 71/73)
+#
+#2005-09-10
+# fix 'unknown' system such that unspecified 'unknown' handler represented by lack of (unknown) variable instead of empty string value
+# this is so that a mixin with an unspecified 'unknown' handler will not undo a lowerlevel 'unknown' specificier.
+#
+#2005-09-07
+# bugfix indexed write to list property
+# bugfix Variable default value
+# 1.0.7.7  (passes 70/72)  
+# fails: 
+# arrayproperty.test    - array-entire-reference
+# properties.test       - property_getter_filter_via_ObjectRef
+#
+#2005-04-22
+# basic fix to PatternPropertyRead dispatch code - updated tests (indexed case still not fixed!)
+#
+# 1.0.7.4
+#
+#2004-11-05
+# basic PropertyRead implementation (non-indexed - no tests!)
+#
+#2004-08-22
+# object creation speedups - (pattern::internals::obj simplified/indirected)
+#
+#2004-08-17
+# indexed property setter fixes + tests
+# meta::Create fixes - state preservation on overlay (correct constructor called, property defaults respect existing values)
+#
+#2004-08-16
+# PropertyUnset & PatternPropertyUnset metaMethods (filter method called on property unset)
+#
+#2004-08-15
+# reference syncing: ensure writes to properties always trigger traces on property references (+ tests)
+# - i.e method that updates o_myProp var in >myObj will cause traces on [>myObj . myProp .] to trigger
+# - also trigger on curried traces to indexed properties i.e list and array elements.
+# - This feature presumably adds some overhead to all property writes - !todo - investigate desirability of mechanism to disable on specific properties.
+#
+# fix (+ tests) for ref to multiple indices on object i.e  [>myObj key1 key2 .] 
+#
+#2004-08-05
+# add PropertyWrite & PatternPropertyWrite metaMethods - (filter method called on property write)
+#
+# fix + add tests to support method & property of same name. (method precedence)
+#
+#2004-08-04
+# disallow attempt to use method reference as if it were a property (raise error instead of silently setting useless var)
+#
+# 1.0.7.1
+# use objectref array access to read properties even when some props unset; + test
+# unset property using array access on object reference; + test
+# 
+#
+#2004-07-21
+# object reference changes - array property values appear as list value when accessed using upvared array.
+# bugfixes + tests - properties containing lists (multidimensional access)
+#
+#1.0.7
+#
+#2004-07-20
+# fix default property value append problem
+#
+#2004-07-17
+# add initial implementation of 'Unknown' and 'PatternUnknown' meta-methods 
+#  (
+#
+#2004-06-18
+# better cleanup on '>obj .. Destroy' - recursively destroy objects under parents subnamespaces.
+#
+#2004-06-05
+#  change argsafety operator to be anything with leading -
+#  if standalone '-' then the dash itself is not added as a parameter, but if a string follows '-'
+#  i.e tkoption style; e.g -myoption ; then in addition to acting as an argsafety operator for the following arg,
+#  the entire dash-prefixed operator is also passed in as an argument.
+#  e.g >object . doStuff -window .  
+#  will call the doStuff method with the 2 parameters -window .
+#  >object . doStuff - .
+#  will call doStuff with single parameter .
+#  >object . doStuff - -window .
+#  will result in a reference to the doStuff method with the argument -window 'curried' in. 
+#
+#2004-05-19
+#1.0.6
+# fix so custom constructor code called.
+# update Destroy metamethod to unset $self
+# 
+#1.0.4 - 2004-04-22
+# bug fixes regarding method specialisation - added test

+# ---------------------
+#!todo - MultiMethod support via transient and persistent object conglomerations. Operators '&' & '@'
+# - a persistent conglomeration will have an object id (OID) and thus associated namespace, whereas a transient one will not.
+#
+#eg1: >x & >y . some_multi_method arg arg 
+#    this is a call to the MultiMethod 'some_multi_method' with 2 objects as the invocants. ('>x & >y' is a transient conglomeration of the two objects)
+#    No explicit 'invocation role' is specified in this call - so it gets the default role for multiple invocants: 'these'
+#    The invocant signature is thus {these 2}
+#    (the default invocation role for a standard call on a method with a single object is 'this' - with the associated signature {this 1})
+#    Invocation roles can be specified in the call using the @ operator.
+#    e.g >x & >y @ points . some_multi_method arg arg   
+#    The invocant signature for this is: {points 2}
+#
+#eg2: {*}[join $objects &] @ objects & >p @ plane . move $path 
+#    This has the signature {objects n plane 1} where n depends on the length of the list $objects
+#   
+#
+#    To get a persistent conglomeration we would need to get a 'reference' to the conglomeration.
+#    e.g set pointset [>x & >y .]
+#    We can now call multimethods  on $pointset
