Tcl 8.6 windows console channels expose no -inputmode configure key, so
punk::console guards testing -inputmode/-mode classified a real 8.6 console
as a pipe. A twapi console handle for stdin is now treated as definitive
console detection at all three affected sites (stdin only - pipe probes
still never touch the process console; mintty-as-pipes has no console
handle and falls through to the env heuristics as before):
1. get_ansi_response_payload's raw-cycling gate (introduced 0.1.5) skipped
the raw cycle for 8.6 line-mode queries.
2. is_input_console_or_tty returned a false negative, making
settle_can_respond's layer-2 heuristic settle a real 8.6 console as
unable to respond.
3. input_at_eof (introduced 0.1.2) took the pipe branch and performed its
probe read on the drained console channel. This was the line-mode query
killer: verified empirically against clean tclkits 8.6.13 and 8.6.17,
a read on a drained 8.6 console channel makes the channel driver park a
blocking cooked-mode ReadConsole; driver reads sample the console mode
when issued, not when data arrives, so the query's subsequent raw flip
cannot rescue it and the terminal response is swallowed until Enter.
Since get_ansi_response_payload calls input_at_eof immediately before
its raw cycle, every 8.6 line-mode query timed out (~500ms) with the
response later leaking to the line reader as phantom input - also the
source of increased ANSI artifacts (e.g. 'help env') once 0.7.0
brokering made code-interp queries actually reach the terminal.
Interactively verified on punksys (tcl 8.6.13, src launch): line-mode
get_cursor_pos and dec_get_mode succeed mid-command, brokered query loops
run clean, and typed-ahead lines are recovered without phantom input.
Known residue (documented in the G-007 detail notes): queries fired while
the repl reader is armed and idle at a line-mode prompt (including some
repl-init detection queries) still hit the parked-read limitation on 8.6 -
repl init ordering is a follow-up; raw mode is unaffected.
Tests: probes.test gains constraint-gated wiring tests for the twapi
console branch of is_input_console_or_tty and input_at_eof (skip in piped
runs, engage on a real console). Full suite passes at baseline (exec-14.3
only) under Tcl 9.0.3; probes suite also verified under Tcl 8.6.

Flip G-007 (location-transparent punk::console) to achieved 2026-07-05 in the
GOALS.md index and detail file. Interactive verification on built punksys
(tcl 8.6) and punk902z (tcl 9) kits (punk::console 0.7.0, opunk::console
0.4.0; punk902z also rerun via src launch against dev modules): fact parity
and immediate cross-context visibility in both directions; brokered terminal
queries from the code interp succeed and cooperate with the repl reader in
raw mode with typed-ahead preserved; a chan-pipe console anchored from the
code interp registers its codethread as owner, operates locally, and clears
its registry entry on forget.
Detail-file Notes record the verification and characterize line-mode reader
cooperation (out of scope, no routing regression - brokered and owner-side
queries behave identically): on tcl 9, complete typed-ahead lines survive
with cosmetic garbling while incomplete typed-ahead starves the query raw
window and leaks responses as phantom input; on tcl 8.6 every line-mode
query fails that way, owner-side included (repro:
repl eval {punk::console::get_cursor_pos}) - candidate owner-side regression
to investigate separately. Also noted: the leaked stderr diagnostics are the
traffic G-011's per-console err channel would house.

Acceptance now names the discovery fact (console_fact_get fact key err,
returning the effective err channel name) so the clause is testable like
G-007's named facts. Detail file additions: "every -console site" is
satisfied at the module's documented resolution choke points
(console_spec_resolve, hybrid_console_spec, opt_console_* helpers,
spec_to_channelpair, shared PUNKARGS fragments) rather than by per-site
audit; the two consumer-shaped acceptance clauses' division of labour is
stated (internal diagnostics migration = first consumer, external consumer
= public emit form); G-001 backends wanting a distinct diagnostic stream
must set err explicitly (default merges into out); and
previous_stty_state_stderr stays as-is (stty-state restoration, orthogonal
to diagnostic routing).

punk::console models two channels per console ({in out}); its own
diagnostics fall back to raw puts stderr and subshell/backend/theme goals
(G-001/G-008/G-009) inherit the dual-channel assumption. G-011 defines err
as an attribute of the canonical {in out} console identity: {in out err}
specs accepted everywhere -console is, a nullable err field on
opunk::Console, err defaulting to process stderr for the default console
and to the console's out channel elsewhere, console-directed diagnostics
and an emit-to-err path, and cross-thread discovery via console_fact_get.
Ownership/fact/mode-cache keys stay canonical {in out}, so the G-007 work
is untouched.
Detail file records the gap analysis, the rejected shapes (err-in-identity
triple key, scope-boundary-only, uniform err==out, unset-means-none) and
the G-001 sequencing interaction.

Per-console facts are now visible to every thread of a punk session: the
default console {stdin stdout} keeps its legacy namespace variables as
authoritative local storage, with write traces mirroring every write
(including direct variable writes) into tsv punk_console_facts; non-default
consoles store facts only in tsv with owner-qualified keys (non-std channel
names are thread-local and would otherwise alias). console_fact_set from a
non-owner thread forwards to the owning thread (vt52-alias transport) and
always writes the tsv mirror itself (covers unreachable or older-version
owners). New console_fact_clear for tests/maintenance.
New console ownership registry (console_owner_register/get/forget, tsv
punk_console_owners keyed by canonical {in out} pair): ownership is captured
when an opunk::console instance is anchored - via the new pluggable
::opunk::console::lifecycle_callback (opunk::console 0.4.0, base class
unchanged) wired by ensure_object_integration - and by default_console.
Consult-time liveness validation clears entries for exited threads. For
{stdin stdout} first registration wins and only the owner's forget releases
the entry, so a thread anchoring a local view cannot steal ownership.
dec_has_mode/ansi_has_mode caches moved to tsv punk_console_modecache
(single-key atomic entries shared process-wide).
Infrastructure tsv arrays are now punk_-prefixed to avoid collisions with
application tsv usage in subshells: console -> punk_console (is_raw), with
call-site patches in punk::repl 0.2.1, punk::lib 0.2.1, punk::basictelnet
0.1.1 (rule recorded in src/modules/AGENTS.md; legacy repl/codethread_*/
zzzload_pkg* arrays left for a coordinated follow-up).
punk::console is now loadable in secondary threads without ::argv0
(powershell consolemode fallback guarded).
Tests: consolefacts gains ownership-registry and cross-thread visibility
coverage (worker-thread punk::console load, trace-mirror, forwarded set with
deadline-polled sync - see comments re runtests child-interp topology);
cleanups use console_fact_clear / tsv instead of poking removed internal
stores. Full suite passes (baseline exec-14.3 only).
G-007 flipped proposed -> active (user-confirmed); remaining acceptance work
is the choke-point brokering slice.

Index entries in GOALS.md plus detail files, all proposed:
- G-007 location-transparent punk::console across repl and code
interps: punk-side tsv-backed ownership registry, fact/cache
visibility, choke-point brokering generalising the vt52 alias;
detail records rejected alternatives (audience namespace split,
owner field on ::opunk::Console, opunk-package-namespace registry)
- G-008 scoped console state for same-console subshells: activatable
per-subshell state sets (journal-on-write, re-emit on activation)
rather than a LIFO undo stack, so later tree switching works;
restore of tabstops/modes/palette on quit; opt-in, shared behaviour
stays default
- G-009 themed subshell profiles: poshinfo schemes bound to
restriction aspects (G-003 limits/hidden commands, punk::island) so
restricted subshells are visually distinct; terminal effects ride
the G-008 state set
- G-010 subshell suspend/resume and tree navigation: switch to any
live subshell (grandparent, cross-branch) via attachment handoff +
G-008 state activation; navigation commands governed by G-003
hide/expose; depends on G-002's non-nested model
Sequencing: G-007 -> G-008 -> G-009/G-010, with G-002 prerequisite
for G-010.

G-001 pluggable console backends for non-detectable terminals (ssh channel, tk widget) via ::opunk::Console subclasses. G-002 non-nested subshell with console targeting and inter-subshell comms, including thread::send -async routing to the code sub-interp and the canonical launch API design (subshell as sole entry point, interp alias as context signal). G-003 configurable resource limits (command-count, time via interp limit) and sandboxing spectrum (interp hide/expose/alias, safe::interpCreate) on subshell interps, downstream of G-002's asymmetry fix.
