G-007 achieved: interactive acceptance verified on tcl 8.6 and tcl 9

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.

 Goal: pre-built binary artifacts can be downloaded from a separate related binary-artifacts repository or user-configured sources, gated by explicit user consent/configuration by default.
 Acceptance: a download mechanism fetches binary artifacts (the same set the zig build produces) from a configured source on demand; by default the download is gated behind explicit user consent (a config flag or interactive prompt) and does not occur silently; a user-configured source URL overrides the default binary-artifacts repo; downloaded artifacts satisfy the same build requirements as zig-built artifacts so `tclsh src/make.tcl project` succeeds with downloaded artifacts in place of built ones.

 Detail: goals/G-007-console-location-transparency.md
 Goal: punk::console presents one API in every interp/thread of a punk session - code-interp callers see the same console facts and can perform the same queries/operations as the parent, routed to the console-owning context via a punk-side ownership registry, with no `repl eval` required.

 Acceptance: from a running punk session's code interp, without `repl eval`: `console_fact_get` returns the same values the parent sees and a fact set in the parent is immediately visible; a terminal query (e.g. `get_cursor_pos` or `dec_get_mode`) against the default console succeeds and cooperates with the repl reader (no lost or garbled input); a console constructed and owned by code-interp code is operated on locally (no round-trip to the parent); the existing console test suites pass and single-interp (non-repl) usage is unchanged.

+- **Line-mode reader cooperation - characterized interactively (punk902z tcl9 + punksys tcl8.6,
+  2026-07-05), no routing regression.** Brokered (code-interp) and owner-side (`repl eval`)
+  queries behave identically in line mode on both runtimes, satisfying the location-transparency
+  intent; the limitations below are properties of line mode's interaction with the query
+  raw-window cycling (the `#review`-flagged line-mode `input_chunks_waiting` path in
+  punk::repl), not artifacts of G-007 brokering, and are out of scope here:
+  - *Complete* typed-ahead lines survive: consumed during the raw window, stashed to
+    `input_chunks_waiting`, recovered and executed after the loop via the line-mode
+    waiting-chunks path (accompanied by the red "chan blocked is true" diagnostic and echo
+    interleaving - cosmetic only, no loss).
+  - *Incomplete* typed-ahead (characters pending without Enter) breaks the query cycle: the
+    in-flight cooked-mode read starves the raw-window response read (per-query timeouts,
+    ~560ms), and the responses later echo outside any read window and are submitted to the
+    line parser as phantom input (e.g. `invalid command name 60`).
+  - On tcl 8.6 (punksys) line mode is worse: *every* query - owner-side included, no routing
+    involved (`repl eval {punk::console::get_cursor_pos}` reproduces it) - times out (~500ms)
+    with the response leaking to the reader and being parsed as input. Raw mode works cleanly
+    on both runtimes, brokered and owner-side. The user recalls 8.6 line-mode queries working
+    previously - candidate owner-side regression somewhere in the punk::console 0.2.0-0.7.0
+    migration or repl reader changes; to be investigated as separate work (also suspected
+    behind increased ANSI artifacts in `help env` output on 8.6).
+  - Raw mode (the repl's own editor) cooperates cleanly in both directions - queries succeed
+    and typed-ahead is preserved intact. Line mode is today's default (raw is the intended
+    future default); fixing line-mode query cooperation would be its own goal.
+    Related: both diagnostics observed (the query-timeout stderr message, the "chan blocked"
+    notice) are the kind of raw diagnostic traffic G-011 gives a defined per-console home.
