Closes #11.

C's command.c 317-338 has a when '+' arm — in the main command
switch, under #ifdef MASTER — that toggles wizard mode. The port had no
'+' anywhere, so the key fell through dispatchKey's default to illcom
and answered "illegal command '+'".

The password half of that arm was dropped deliberately (wizard mode is
ROGUE_WIZARD configuration) and is recorded in ARCHITECTURE.md §9.
The leave half was lost silently, and it is a different decision: it does
not touch the password machinery. The substantive part of it is
turn_see(TRUE), not the flag — wizard sight draws every monster the hero
cannot see, so without the re-hide there is no way back to normal
visibility, and clearing the flag alone would leave the screen lying.

What changed

  • game/command.go: new wizardToggleCommand. After = false; in wizard
    mode it clears Wizard, calls g.turnSee(true) and prints
    "not wizard any more"; otherwise "sorry".
  • game/tables.go: '+' registered in commandHandlers between '^' and
    Escape — C's own switch order. Because C's arm is in the main switch
    rather than the if (wizard) switch (ch) sub-switch that wizardCommand
    ports, it is reachable whether or not wizard is set; commandHandlers
    is the faithful home, and the non-wizard case was a divergence too.
  • The non-wizard choice, stated in the function's doc comment and in
    §9: a password check that no longer exists can never succeed, so the
    else arm is exactly what C did on a wrong answer — "sorry", with no
    prompt (nothing typed into one could change the outcome) and none of the
    noscore/turn_see(FALSE) bookkeeping of C's unreachable success branch.
  • game/wizard_test.go: two tests, both driving '+' through g.dispatch.
  • ARCHITECTURE.md §9: the password row now names the '+' enter arm
    as the dropped part, and a new paragraph records that the leave arm is
    ported in full.
  • TODO.md: Completed Steps entry. Next Step deliberately not rotated
    (out-of-band issue work).

C sources each claim was verified against

Read via git show; c-master was not checked out or modified.

  • origin/c-master:command.c 317-338 — the #ifdef MASTER / when '+' /
    #endif block, both arms, and its position immediately before
    otherwise: in the main switch (the wizard sub-switch starts at 369).
    The issue cited 316-336; cosmetic drift, everything else in it held.
  • origin/c-master:potions.c 267-306 — turn_see. The turn_off arm
    redraws t_oldch at every monster the hero cannot see and clears
    SEEMONST, and reaches no rnd call (only the turn-on arm does).
    origin/c-master:rogue.h:691 for the declaration.
  • origin/c-master:wizard.c 233-257 — passwd(): it prompts, reads a
    line, and compares md_crypt(buf, "mT") against PASSWD. An empty
    answer returns FALSE, which is the branch this port is permanently on.
  • Message strings taken verbatim from those sources: "not wizard any more"
    and "sorry".

Verification

  • make check green on the branch: fmt-check clean, golangci-lint
    0 issues, make test (-timeout 30s -race -cover) ok for all
    packages. The only linter output beyond that is the known gomodguard
    deprecation warning (#29).
  • Lint ran against a private GOLANGCI_LINT_CACHE in a fresh empty
    directory, not the shared host cache; the run named no path outside the
    branch's own worktree.
  • make test re-run with the Go test cache bypassed, so the green is not a
    cache hit.
  • Mutation-proved: deleting the turnSee(true) call fails
    TestWizardToggleOffRehidesSensedMonsters on all three visibility
    assertions — SenseMonsters still set, cell still 'P', cell still in
    standout — which is exactly what a flag-only test would have missed.
  • RNG order untouched: no rnd call added, and TestSeedCompatItemTables
    passes against the golden, which was not regenerated or edited.
  • .golangci.yml unmodified (sha256 still
    021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb).
  • Work was done in a throwaway worktree; the shared clone stayed on main
    and clean.

C's command.c 317-338 has a `when '+'` arm in the main command switch,
under #ifdef MASTER, that toggles wizard mode. The port had no '+' at
all, so the key fell through dispatchKey's default to illcom and
answered "illegal command '+'".

The password half of that arm was dropped deliberately (wizard mode is
ROGUE_WIZARD configuration) and is recorded in ARCHITECTURE.md section
9. The leave half was lost silently, and it is a different decision: it
does not touch the password machinery. The substantive part of it is
turn_see(TRUE) rather than the flag -- wizard sight draws every monster
the hero cannot see, so without the re-hide there is no way back to
normal visibility, and clearing the flag alone would leave the screen
lying.

New wizardToggleCommand, registered in commandHandlers between '^' and
Escape, which is C's own switch order. Because C's arm sits in the main
switch rather than the `if (wizard) switch (ch)` sub-switch that
wizardCommand ports, it is reachable whether or not wizard is set, so
the non-wizard case was a divergence too. It resolves the way the
dropped passwd() forces: a password check that no longer exists can
never succeed, so the else arm is what C did on a wrong answer -- the
message "sorry", with no prompt, since nothing typed into one could
change the outcome, and none of the noscore/turn_see(FALSE) bookkeeping
of C's unreachable success branch. The choice is stated in the doc
comment and in section 9.

Two tests drive '+' through g.dispatch. The wizard one spawns a phantom
(ISINVIS straight from the monster table, so seeMonst is false and it is
on screen only because wizard sight put it there), asserts the
precondition, then asserts the flag cleared, SenseMonsters cleared, the
cell restored to the map char under the monster with standout off, the
exact message text, and After false. Deleting the turnSee(true) call
fails it on all three visibility assertions. The other pins "sorry".

No RNG call is added: the turn_off arm of turn_see never reaches rnd.
TestSeedCompatItemTables is green against the untouched golden.

What is in this branch

One commit, c95f98f, on fix/wizard-toggle-off off main @ 630038e.

game/command.go — new wizardToggleCommand():

  • After = false unconditionally, as C's arm does first.
  • In wizard mode: g.Wizard = false, then g.turnSee(true), then
    g.msg("not wizard any more") — C's order exactly.
  • Otherwise: g.msg("sorry").
  • The doc comment carries the (command.c command) breadcrumb and states
    the dropped-password reduction in full.

game/tables.go'+': (*RogueGame).wizardToggleCommand in
commandHandlers, placed between '^' and Escape, which is where the arm
sits in C's switch.

ARCHITECTURE.md §9 — the "DES crypt wizard password" row now reads
"DES crypt wizard password (passwd(), the '+' enter arm)", and a new
paragraph after the table records that the leave arm is ported in full as
wizardToggleCommand, that turnSee(true) is why, and that '+' outside
wizard mode reduces to "sorry".

TODO.md — Completed Steps entry in the same commit. Next Step was
deliberately not rotated: this is out-of-band issue work, matching the
convention the last four issue entries use.

Where the issue was right, and the one place it drifted

Every substantive premise checked out. Two refinements:

  1. Line numbers: the block is command.c 317-338 (#ifdef MASTER 317,
    when '+': 318, #endif 338), not 316-336. Cosmetic.
  2. Placement, which does change the code: '+' is in C's main command
    switch, immediately before otherwise:, not in the
    if (wizard) switch (ch) sub-switch (that one starts at line 369) which
    wizardCommand/wizardDebugCommand port. Under MASTER, C therefore
    reaches '+' whether or not wizard is set. So the faithful home is
    commandHandlers, not wizardCommand — and the non-wizard path was a
    divergence too, answering "illegal command '+'" where C answers "sorry".
    The issue's DoD item 2 anticipated this; it is worth naming because
    putting the handler in wizardCommand would have looked right and left
    half the bug in place.

C sources each claim was verified against

All read with git show; c-master and modern-rogue were not checked out
or touched.

Claim Source
the '+' arm exists, both halves, in main switch origin/c-master:command.c 317-338, otherwise: at 366
the wizard sub-switch is separate origin/c-master:command.c 369-405
turn_see semantics and no rnd on the off arm origin/c-master:potions.c 267-306
turn_see declaration origin/c-master:rogue.h:691
passwd() is a DES compare that can only fail origin/c-master:wizard.c 233-257

Message strings are byte-for-byte from command.c: "not wizard any more"
and "sorry". They are asserted raw against MessageLine.Huh, which is
captured before endmsg's display-time capitalization, so the test pins the
contract text rather than the rendered text.

How it was tested

game/wizard_test.go gains two tests, both t.Parallel(), in a file that
already carries the approved //nolint:testpackage header.

TestWizardToggleOffRehidesSensedMonsters — the substantive one. It spawns
a phantom next to the hero; a phantom carries Invisible straight from the
monster table, so seeMonst is false for it and it is on screen only
because wizard sight put it there. The test asserts its preconditions before
asserting anything else (monster is genuinely unseeable, the map char under
it differs from its glyph, turnSee(false) set SenseMonsters and drew
'P' in standout at its cell), then drives g.dispatch('+') and checks:
Wizard cleared, SenseMonsters cleared, the cell restored to the
monster's OldCh, standout off, message "not wizard any more", After
false.

TestWizardToggleWithoutWizardSaysSorry'+' with Wizard false: wizard
mode stays off, SenseMonsters is untouched, message "sorry", After
false.

Mutation proof. Deleting the g.turnSee(true) call makes the first test
fail on all three visibility assertions and on none of the others:

--- FAIL: TestWizardToggleOffRehidesSensedMonsters
    wizard_test.go:481: '+' left SenseMonsters set: turn_see(TRUE) was not performed
    wizard_test.go:485: monster still on screen after leaving wizard mode: cell is 'P', want the map char under it, '.'
    wizard_test.go:490: cell left in standout after leaving wizard mode

That is the half a flag-only test would have missed, which is why the issue
insisted on it.

Gate

  • make check green: fmt-check clean, golangci-lint 0 issues,
    make test (-timeout 30s -race -cover) ok on all three packages.
  • The lint run used GOLANGCI_LINT_CACHE pointed at a fresh empty directory
    created for this branch, not the shared host cache, so the 0 cannot be a
    stale shared-cache artifact. Its output named no path outside this
    branch's own worktree. The only extra output was the known gomodguard
    deprecation warning tracked as #29, untouched here.
  • make test was also re-run with the Go test cache bypassed, so the green
    is a real execution rather than a cache hit.
  • TestSeedCompatItemTables passes against game/testdata/item_tables.golden
    exactly as committed — the golden was neither edited nor regenerated, and
    no rnd call was added (the turn_off arm of turn_see reaches none).
  • .golangci.yml untouched; sha256 still
    021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb.
  • All work happened in a throwaway git worktree, removed after the push; the
    shared clone stayed on main and clean throughout.

Review of PR #30fix/wizard-toggle-off @ c95f98f (base main @ 630038e)

Verdict: PASS.

Independent review; reviewer did not author the change. All C claims were
re-verified from scratch via git show origin/c-master:...; c-master and
modern-rogue were not checked out. Work was done in a throwaway worktree,
which has been removed; the shared clone was left on main and clean.

Adjudication of the author's correction to issue #11

The author is right, and the issue was wrong. Verified independently:

  • origin/c-master:rogue.h:52-53#define when break;case and
    #define otherwise break;default. The when macro claim holds.
  • origin/c-master:command.c#ifdef MASTER at 317, when '+': at
    318, #endif at 338. The issue's 316-336 is off by one line at each
    end. Cosmetic; the author's numbers are the correct ones.
  • The block sits in the main command switch: when '^': at 300 precedes it,
    when ESCAPE: at 339 follows it, otherwise: is at 366, and the
    if (wizard) switch (ch) sub-switch that wizardCommand/wizardDebugCommand
    port opens at 369 (inside #ifdef MASTER at 368, #endif at 425). '+'
    is not in that sub-switch.
  • Consequence confirmed: under MASTER, C reaches '+' regardless of the
    wizard flag. commandHandlers is therefore the faithful home, and the
    not-in-wizard-mode path was a live divergence too ("illegal command '+'" vs
    C's "sorry"). Had the handler gone into wizardCommand per the issue's
    framing, half the bug would have survived while looking fixed.

One prose inaccuracy in the PR description and the issue comment, non-blocking
and not present in the repo: both say the arm sits "immediately before
otherwise:". It does not — six arms (ESCAPE, 'm', ')', ']', '=',
'@') sit between #endif at 338 and otherwise: at 366. The load-bearing
claim (main switch, not the wizard sub-switch) is unaffected, and the code,
the doc comment, TODO.md and ARCHITECTURE.md all describe the placement
correctly ("between '^' and Escape", which is exactly C's order).

Itemized verification

  1. Message text. command.c:324 is msg("not wizard any more") and
    command.c:336 is msg("sorry"). Both strings in
    game/command.go:419,428 match byte-for-byte, including the two-word
    "any more" and the lowercase "sorry". Both are asserted raw against
    MessageLine.Huh, which game/io.go:57-60 captures from the buffer in
    End() before the display-time capitalization at io.go:67-71 — so the
    tests pin the contract text, not the rendered text. Correct choice.
  2. Order of operations on the leave arm. command.c:322-324 is
    wizard = FALSE;turn_see(TRUE);msg(...).
    game/command.go:424-428 is g.Wizard = falseg.turnSee(true)
    g.msg(...). Identical, and the order matters: turnSee calls
    seeMonst, so clearing the flag first is what makes the re-hide see the
    post-wizard world.
  3. turnSee(true) vs turn_see(TRUE). origin/c-master:potions.c:270-306
    against game/potions.go:295-317: same loop over the monster list, same
    move then can_see = see_monst(mp), same if (!can_see) addch(t_oldch)
    on the off arm, same SEEMONST clear after the loop. The re-hide is real.
    Pre-existing code, unchanged by this PR.
  4. Password-path reduction. Verified against
    origin/c-master:wizard.c:233-258. passwd() prints
    "wizard's Password:", reads a line, returns FALSE on an empty answer and
    otherwise compares md_crypt(buf, "mT") against PASSWD. C's wrong-answer
    path then falls to command.c:335-336, which prints "sorry" and does
    nothing else — no state change, and wizard was already assigned FALSE
    from passwd(). So the reduction to a bare "sorry" is exactly C's
    reachable behaviour. C does prompt first; dropping the prompt is right,
    because with no stored hash there is nothing the input could be compared
    against and the outcome is fixed before the read. Dropping
    noscore/turn_see(FALSE) is right for the same reason — both belong to
    the unreachable success branch — and separately noscore is not lost from
    the port at all: game/command.go:119-121 (turnUpkeep) already sets
    g.NoScore = true every turn while g.Wizard. The doc comment at
    game/command.go:405-414 states the reduction and its reasoning in full,
    with the ROGUE_WIZARD/§9 pointer. Adequate.
  5. After = false. command.c:319 sets after = FALSE before the
    if (wizard), i.e. on both arms. game/command.go:416 sets it
    unconditionally at the top. Matches; '+' consumes no turn, so daemon and
    fuse sequencing is unchanged. Both tests assert it after presetting
    g.After = true.
  6. Dispatch-table placement. game/tables.go:805 adds
    '+': (*RogueGame).wizardToggleCommand between '^' and Escape — C's own
    switch order. commandHandlers is a map, so the position is stylistic only.
    No key is shadowed or displaced: '+' had no prior entry, wizardCommand
    and wizardDebugCommand contain no '+' case, and the only other '+'
    literals in non-test code are the Door glyph (game/types.go:48) and the
    blessing prompt (game/wizard.go:84,96), neither of which is a command key.
    The diff touches no other handler.
  7. Tests — mutation reproduced. Deleting g.turnSee(true) from
    game/command.go:427 and running GOFLAGS=-count=1 make test, the failure
    is exactly as claimed and confined to one test:

    No other test fails, including TestSeedCompatItemTables. Two further
    mutations confirm the rest is non-vacuous: removing g.After = false fails
    wizard_test.go:498 and :529 in both tests; changing the strings to
    "not wizard anymore" / "Sorry" fails wizard_test.go:494 and :525.
    The visibility half is genuinely load-bearing — a flag-only test would have
    passed all three mutations that matter. The preconditions
    (wizard_test.go:437-462) are asserted with t.Fatal before the act, so
    the test cannot silently degrade into asserting nothing: it proves the
    phantom is Invisible, that seeMonst is false for it, that OldCh differs
    from Type, and that turnSee(false) actually drew it in standout.
  8. RNG order. potions.c reaches rnd only on the turn-on arm
    (rnd(26) + 'A', the hallucinating draw); the turn_off arm has no rnd
    call, and the Go mirror keeps that split (showSensed holds the turn-on
    arm). No rnd call is added anywhere in the diff, nothing under
    game/testdata/ is touched, and TestSeedCompatItemTables passes against
    the committed golden.
  9. ARCHITECTURE.md §9. Accurate. The password row now reads
    "DES crypt wizard password (passwd(), the '+' enter arm)", which is
    precisely the dropped half, and the new paragraph correctly states that the
    leave arm is ported in full, why turnSee(true) is the substantive part,
    and what the else arm reduces to. Table column alignment is intact (all rows
    68 chars in column 1).

Non-blocking observations

  • The "immediately before otherwise:" phrasing in the PR body and in the

    change requested.
  • wizardToggleCommand never enters wizard mode, so the name is slightly
    broader than the behaviour. It is the right name for C's command, the doc
    comment resolves it immediately, and it is consistent with the neighbouring
    identifyTrapCommand / wizardCommand. No change requested.
## Review of PR #30 — `fix/wizard-toggle-off` @ `c95f98f` (base `main` @ `630038e`) **Verdict: PASS.** Independent review; reviewer did not author the change. All C claims were re-verified from scratch via `git show origin/c-master:...`; `c-master` and `modern-rogue` were not checked out. Work was done in a throwaway worktree, which has been removed; the shared clone was left on `main` and clean. ### Adjudication of the author's correction to issue #11 **The author is right, and the issue was wrong.** Verified independently: - `origin/c-master:rogue.h:52-53` — `#define when break;case` and `#define otherwise break;default`. The `when` macro claim holds. - `origin/c-master:command.c` — `#ifdef MASTER` at **317**, `when '+':` at **318**, `#endif` at **338**. The issue's 316-336 is off by one line at each end. Cosmetic; the author's numbers are the correct ones. - The block sits in the **main** command switch: `when '^':` at 300 precedes it, `when ESCAPE:` at 339 follows it, `otherwise:` is at 366, and the `if (wizard) switch (ch)` sub-switch that `wizardCommand`/`wizardDebugCommand` port opens at **369** (inside `#ifdef MASTER` at 368, `#endif` at 425). `'+'` is not in that sub-switch. - Consequence confirmed: under `MASTER`, C reaches `'+'` regardless of the `wizard` flag. `commandHandlers` is therefore the faithful home, and the not-in-wizard-mode path was a live divergence too ("illegal command '+'" vs C's "sorry"). Had the handler gone into `wizardCommand` per the issue's framing, half the bug would have survived while looking fixed. One prose inaccuracy in the PR description and the issue comment, non-blocking and not present in the repo: both say the arm sits "immediately before `otherwise:`". It does not — six arms (`ESCAPE`, `'m'`, `')'`, `']'`, `'='`, `'@'`) sit between `#endif` at 338 and `otherwise:` at 366. The load-bearing claim (main switch, not the wizard sub-switch) is unaffected, and the code, the doc comment, `TODO.md` and ARCHITECTURE.md all describe the placement correctly ("between `'^'` and `Escape`", which is exactly C's order). ### Itemized verification 1. **Message text.** `command.c:324` is `msg("not wizard any more")` and `command.c:336` is `msg("sorry")`. Both strings in `game/command.go:419,428` match byte-for-byte, including the two-word "any more" and the lowercase "sorry". Both are asserted raw against `MessageLine.Huh`, which `game/io.go:57-60` captures from the buffer in `End()` before the display-time capitalization at `io.go:67-71` — so the tests pin the contract text, not the rendered text. Correct choice. 2. **Order of operations on the leave arm.** `command.c:322-324` is `wizard = FALSE;` → `turn_see(TRUE);` → `msg(...)`. `game/command.go:424-428` is `g.Wizard = false` → `g.turnSee(true)` → `g.msg(...)`. Identical, and the order matters: `turnSee` calls `seeMonst`, so clearing the flag first is what makes the re-hide see the post-wizard world. 3. **`turnSee(true)` vs `turn_see(TRUE)`.** `origin/c-master:potions.c:270-306` against `game/potions.go:295-317`: same loop over the monster list, same `move` then `can_see = see_monst(mp)`, same `if (!can_see) addch(t_oldch)` on the off arm, same `SEEMONST` clear after the loop. The re-hide is real. Pre-existing code, unchanged by this PR. 4. **Password-path reduction.** Verified against `origin/c-master:wizard.c:233-258`. `passwd()` prints `"wizard's Password:"`, reads a line, returns `FALSE` on an empty answer and otherwise compares `md_crypt(buf, "mT")` against `PASSWD`. C's wrong-answer path then falls to `command.c:335-336`, which prints `"sorry"` and does nothing else — no state change, and `wizard` was already assigned `FALSE` from `passwd()`. So the reduction to a bare `"sorry"` is exactly C's reachable behaviour. C does prompt first; dropping the prompt is right, because with no stored hash there is nothing the input could be compared against and the outcome is fixed before the read. Dropping `noscore`/`turn_see(FALSE)` is right for the same reason — both belong to the unreachable success branch — and separately `noscore` is not lost from the port at all: `game/command.go:119-121` (`turnUpkeep`) already sets `g.NoScore = true` every turn while `g.Wizard`. The doc comment at `game/command.go:405-414` states the reduction and its reasoning in full, with the `ROGUE_WIZARD`/§9 pointer. Adequate. 5. **`After = false`.** `command.c:319` sets `after = FALSE` before the `if (wizard)`, i.e. on both arms. `game/command.go:416` sets it unconditionally at the top. Matches; `'+'` consumes no turn, so daemon and fuse sequencing is unchanged. Both tests assert it after presetting `g.After = true`. 6. **Dispatch-table placement.** `game/tables.go:805` adds `'+': (*RogueGame).wizardToggleCommand` between `'^'` and `Escape` — C's own switch order. `commandHandlers` is a map, so the position is stylistic only. No key is shadowed or displaced: `'+'` had no prior entry, `wizardCommand` and `wizardDebugCommand` contain no `'+'` case, and the only other `'+'` literals in non-test code are the `Door` glyph (`game/types.go:48`) and the blessing prompt (`game/wizard.go:84,96`), neither of which is a command key. The diff touches no other handler. 7. **Tests — mutation reproduced.** Deleting `g.turnSee(true)` from `game/command.go:427` and running `GOFLAGS=-count=1 make test`, the failure is exactly as claimed and confined to one test: ``` --- FAIL: TestWizardToggleOffRehidesSensedMonsters wizard_test.go:481: '+' left SenseMonsters set: turn_see(TRUE) was not performed wizard_test.go:485: monster still on screen after leaving wizard mode: cell is 'P', want the map char under it, '.' wizard_test.go:490: cell left in standout after leaving wizard mode ``` No other test fails, including `TestSeedCompatItemTables`. Two further mutations confirm the rest is non-vacuous: removing `g.After = false` fails `wizard_test.go:498` and `:529` in both tests; changing the strings to `"not wizard anymore"` / `"Sorry"` fails `wizard_test.go:494` and `:525`.

Manager notes (the review is in its own comment above).

Verdict accepted: PASS. Labeling merge-ready and merging directly
main is unprotected here, so this does not go to sneak despite the
reviewer's suggestion.

My issue was wrong in a way that would have produced a half-fix. I said
'+' belongs in wizardCommand/wizardDebugCommand. It does not: it sits in
C's main command switch (when '^': at 300, when '+': at 318,
when ESCAPE: at 339), while the if (wizard) switch (ch) sub-switch that
those functions port does not open until 369.

The consequence is the part I would have missed entirely: under MASTER, C
reaches '+' regardless of whether wizard is set, so the non-wizard path
was a second live divergence — Go answered "illegal command '+'" where C
answers "sorry". Implementing my version would have fixed the wizard arm,
looked correct, and left the other half broken with nothing to catch it.

The reviewer verified the correction from primary sources rather than
adjudicating between two agents' assertions
, which is what made this
conclusive: rogue.h:52-53 confirms #define when break;case, and the
line-by-line reading of command.c places the block precisely. It also
corrected the author's line numbers (317-338, not my 316-336).

Three mutations, not one. The author proved deleting g.turnSee(true)
fails the visibility test; the reviewer reproduced that and added two more —
removing g.After = false fails the turn-consumption assertions, and altering
the message strings fails the text assertions. Each mutation fails only its
own assertions. That is a materially stronger claim than "the test passes",
and it is the standard I want on this repo after #26.

Two details worth recording because they show the check went past the obvious:

  • The message assertions pin contract text, not display text. They assert
    against MessageLine.Huh as captured before the display capitalization in
    game/io.go:67-71. Asserting post-capitalization would have silently
    tolerated a change to the stored string.
  • noscore is not lost. C's unreachable success branch sets it; the
    reviewer confirmed the port already sets g.NoScore = true every turn while
    g.Wizard in turnUpkeep, so dropping that bookkeeping from the reduction
    costs nothing. That is exactly the sort of "the reduction drops something
    that matters" risk I wanted checked.

The one inaccuracy found is confined to the PR body and my issue comment,
not the repo: both say the arm sits "immediately before otherwise:" when six
arms sit between. The code, doc comment, TODO.md, and ARCHITECTURE.md §9
all describe the placement correctly, so nothing false lands in the tree.
Correctly non-blocking.

Follow-up filed as #31: nothing has ever checked C's command switch against
Go's dispatch table, and '+' was found by accident rather than by audit. A
missing dispatch entry is uniquely invisible in a function-by-function port —
no dangling reference, no compile error, fails only when a player presses the
key. That issue asks for a regression test, not just a sweep.
