#0.5.1 - G-076: repl::start's dead-console watchdog arming now also requires punk::lib::check::has_tclbug_console_deadspin to report the runtime affected (shared version gate with the 'help tcl' warning; requires punk::lib 0.4.2+). Behaviour today is unchanged (gate variable check::tclbug_console_deadspin_fixed_in is empty = every Tcl 9 windows runtime affected); once a released Tcl containing the verified upstream fix for f10d91c2d3 is recorded there, such runtimes stop arming the watchdog. |

#0.5.0 - G-039: new repl::console_watchdog - a self-rescheduling liveness poll (default 5s, repl::console_watchdog_ms) armed by repl::start for a tcl9 console input channel (-inputmode present) serving the process-default console on windows. The Tcl 9 windows console driver never delivers a dead console (killed conhost/terminal) to the script level as a fileevent (tclWinConsole.c ConsoleEventProc only notifies on buffered data) and its reader thread busy-loops on the persistent channel error, so an orphaned shell previously spun ~2 cores indefinitely. On a failed probe (chan configure -inputmode = live GetConsoleMode) the watchdog closes the input channel (stopping the driver reader thread) and finishes the repl via the normal eof done-path; app-punkshell's eof handling then finds no console reopenable and exits cleanly. repl::start's post-vwait reader-deregistration now tolerates an inchan closed by the watchdog. Piped/foreign-console/tcl8.6 inputs are unaffected (watchdog not armed). |

#0.4.0 - G-001: repl::init -console <spec> selects the console the repl reads/writes ({in out} pair, anchored opunk::console instance name, or ::opunk::Console object value, resolved via punk::console::console_spec_resolve). repl::start's inchan is now optional (defaults to the selected console's input). New repl-level channel state (conin/conout/conerr) is routed through rputs (stdout/stderr mapped per-repl) and doprompt; for a selected foreign console the code interp's stdout/stderr are diverted via shellfilter 'var' junction stacks and emitted to the console after each run. New helpers repl::console_is_default / console_at_eof / console_get_size - eof and size are answered by the selected console object's (possibly overridden) methods. Process-console behaviours (tcl_interactive prompt gating, stdin reopen on eof, raw-mode re-enable, utf-16be windows line re-decode experiment, mode-line on exit) now apply only to the default console. Default-console (stdin/stdout) behaviour unchanged. Also fixes rputs pseudo-channel mapping in the 3-arg -nonewline form (mapped value previously written over the -nonewline flag). |

#0.3.0 - G-058: codethread init script receives the runtime static/builtin package baseline (::punkboot::static_prefixes/static_packages via new %staticprefixes%/%staticpackages% scriptmap entries) and seeds ifneeded mappings in the codethread interp, so the code interp (seeded in turn via punk::lib::interp_sync_package_paths) can package-require statically-linked runtime packages - fixes 'can't find package Thread' booting a punk9win.vfs kit on the tclsfe-x64 static runtime (punk91) |

#0.2.2 - repl_handler line-mode waiting-chunks path no longer performs its opportunistic unsized read on tcl 8.6 windows console channels (no -inputmode key, real twapi console handle): the path is entered via 'after idle' with the channel usually drained, and on the 8.6 console driver a drained read parks a blocking cooked-mode ReadConsole that a later raw flip cannot cancel - after typed-ahead was stashed during a terminal-query raw window, that parked read swallowed every subsequent query response in the session until Enter (companion to the punk::console 0.7.1 three-site console-misdetection fix). On such consoles the path now consumes only data already in the Tcl channel buffer (chan pending input + sized read - no driver probe); with nothing buffered it processes the stashed complete lines directly and arms the readable handler for any remaining partial line (replacing an after-idle reinvoke that could never progress). Behaviour on tcl 9/8.7 (-inputmode consoles) and in raw mode is unchanged. |

#0.2.1 - call-site update for punk::console 0.6.0 tsv array rename: console -> punk_console (is_raw); no behaviour change |
|
#0.2.0 - codethread init_script now propagates package prefer via %packageprefer% scriptmap entry |
|
#0.2.0 - code interp (punk/0 repltype) now uses punk::lib::interp_sync_package_paths -libunknown 1 instead of manual epoch-only copy, propagating tm list, auto_path, package prefer, and libunknown to the code interp |
|
#0.1.6 - repl::init routes default console construction through punk::console::default_console (also gains the probe-byte store unification) |
|
#0.1.5 - repl::init comment updated: ambiguous capability settles at first console use via punk::console::settle_can_respond (no behaviour change) |
|
#0.1.4 - repl::init constructs the process-default console object (opunk::console instance: default) and settles can_respond 1 for interactive stdin (negative settle deliberately not done at init - see comment) |
|
#0.1.3 - repl::start now cancels the deferred (after idle) stdin reader registration when the repl finishes, preventing a stale registration re-attaching a reader to a completed repl |
|
#0.1.3 - repl_process_data drops input that arrives after codethread teardown instead of raising 'invalid thread handle ""' from thread::send
