Confirm the Windows build pipeline works end to end: real .msi produced

The -arch x64 fix (previous commit) is confirmed live: build_errorlevel=0,
BUILD_DONE, a real 958MB FEnigma-0.1.0.msi written to Z:\dist -- the
first ever fully successful build this pipeline has produced. Copied
to dist-windows/FEnigma-0.1.0.msi (gitignored).

Not yet installed/launched on a real Windows machine to confirm the
app actually runs -- packaging succeeding isn't the same claim as the
app working once installed, per this repo's own README note. Logged
as the next thing to check, along with light.exe's own ~15-18min
runtime now that there's a clean build to measure it against.

       accept attempt after that silently died before the ally/target

       Fixed there; not a separate bug.
+- [x] "Accept as…" (the type-picker submenu on a proposal, and "Change
+      type" on an already-placed entity) opening to a visibly empty/
+      unchanged popover. This one left no traceback at all -- confirmed
+      live with temporary debug prints that the button's `clicked` signal
+      fires, the icon grid builds successfully (all N types), and
+      `Popover.set_child()` on the already-open outer popover reports the
+      right `visible=True`/width/height afterward... but the compositor
+      never actually repaints that reused surface, so nothing new ever
+      appeared on screen. Fixed by not resizing the existing open
+      popover at all: popping it down and opening a genuinely new one
+      (fresh native surface) at the same anchor point instead. Same fix
+      applied to both call sites (`_open_proposal_menu`'s `show_type`,
+      `_open_entity_menu`'s `show_type`, the latter refactored to share
+      the same `_reopen_with()` helper).
+- [x] New: mark a Target as underground, at a hardening tier (1-3),
+      rendered as the game's own Armor-tier additive badge stacked on
+      the icon. `Target.underground_tier: int | None`, a "Mark
+      underground" entry in the entity-edit popover (tier picker reusing
+      the same fresh-popover fix above), and `GridCanvas` draws the
+      badge above the marker's icon, overlapping down into it by
+      `_ADDITIVE_OVERLAP_PX` -- both the diamond icon's top corner and
+      the badge's bottom are tapered to a near-point, not a flat edge,
+      so bbox-exact touching still read as a gap; a real pixel overlap
+      is what actually looks contiguous (confirmed against the game's
+      own stacked-badge screenshots). Badge is scaled/positioned off the
+      art's real opaque content (PIL `getbbox()`), not its PNG canvas --
+      the additive files carry a lot of off-center transparent padding
+      that made the badge look tiny and floating if sized off the raw
+      canvas.

-- [ ] Enemy type detection needs to be more robust; read the entity id
+- [~] Enemy type detection needs to be more robust; read the entity id
       label so dedup is reliable; detect death from the log.
-      All three are real computer-vision/OCR feature work (better marker
+
-      classification in `map_vision.py`'s `classify_marker`, a new OCR pass
+      Started on the id-reading piece: `map_vision.read_marker_id` reads
-      reading each marker's id label off the map screenshot, and a
+      each marker's own small "#<N>" label (distinct from the big
-      "<Type>#<id> Destroyed" log-scan tied into a dedup key that includes
+      per-cell grid label `read_cell_label` reads) via the SAME template-
-      that read id) rather than bugs with a small fix. Worth its own pass
+      correlation approach as `read_cell_label`, not OCR -- this text
-      once there's a batch of the `debug_capture` failure/maybe_map
+      sits over the same aerial-photo backdrop that this module's own
-      screenshots above to develop against.
+      docstring says defeated every detection-based approach tried for
+      grid labels, so pytesseract (already tried elsewhere in this repo,
+      `ocr.py`, for a different image domain: flat scanned paper, not
+      photo-textured) was skipped in favor of the approach already proven
+      here. Wired end-to-end: `find_markers` -> `Proposal.detected_id` ->
+      `debug_capture.save_marker_ground_truth`'s JSON. Reads against
+      `ScreenshotImport.full_image` (sharper than the WORK_W image
+      detection itself runs against) when available. Crop region and
+      `MIN_MARKER_ID_SCORE` are a single-screenshot calibration (see
+      `read_marker_id`'s own docstring) -- UNVALIDATED against a real
+      ground-truth batch (none of the 6 existing captures have a
+      confirmed id to check against, they all predate this). New unit
+      tests (`tests/test_map_vision_marker_id.py`) only cover the
+      synthetic-render round-trip, not real-screenshot accuracy.
+
+      Measured type-detection reliability against the 6 existing
+      `marker_ground_truth` captures (72 accepted proposals total,
+      2026-08-13): **0/72 (0%) had ANY confident `detected_unit` guess**
+      -- `classify_marker` returned `None` on every single one, every
+      side, every capture. Not "guesses wrong" -- never confident enough
+      to answer at all. Spot-checked directly against one real marker
+      crop (a hostile Infantry, confirmed by the user): best match was
+      "Underground Fort" at score 0.376 (Infantry wasn't even in the top
+      8), against a `min_score=0.55` floor `classify_marker` requires --
+      not a close miss, a real correlation failure. The clean rendered
+      icon templates `icon_bank()` matches against apparently don't
+      correlate well with how markers actually look in a real screenshot
+      (compression/blur/aerial-photo texture underneath), unlike text
+      glyphs (`read_cell_label`'s measured 0.73-0.87 vs 0.40-0.56) where
+      the same template-correlation idea works well. Added `unit_score`/
+      `unit_margin` to `Proposal`/ground-truth JSON (previously only
+      pass/fail `unit` was logged) so every future capture shows exactly
+      how far off a guess was, not just None -- there was no way to tell
+      "barely missed the bar" from "wildly wrong" before this.
+
+      Death-detection-from-log is still fully unstarted -- no log-parsing
+      code exists in this repo at all yet, real scope work (find/access
+      the game's log, agree a "<Type>#<id> Destroyed" grammar, wire it
+      into a dedup key) rather than a quick pass.
+
+      Follow-ups from user feedback after the above landed:
+      - `_accept_proposal` now actually USES `detected_id` (it was only
+        being logged before, never applied) -- an accepted proposal's
+        entity id prefers the detected number over auto-assignment,
+        falling back on a collision. 4 new regression tests
+        (`tests/test_app_accept_proposal.py`).
+      - Auto-assignment itself (`Board.add_target`/`add_ally` with no
+        `id_`/no usable detection) changed from one shared letter
+        sequence per group (targets, or allies) to its own sequence per
+        TYPE within each group -- Tank#A/Infantry#A rather than
+        Tank#A/Infantry#B. This directly reverses an earlier deliberate
+        fix in this same file (see the "Allies and enemies seem to share
+        indices" entry above, which moved FROM per-type TO
+        shared-per-group) -- that fix is still correct for what it fixed
+        (targets-vs-allies must stay separate namespaces), just not for
+        per-type-vs-shared, which the user has now clarified the other
+        way. Tests in `test_models.py` updated to match (renamed
+        `test_auto_id_is_shared_across_types...` ->
+        `test_auto_id_is_per_type...`, since it now asserts the opposite).
+
+        First pass at this ALSO switched auto-assignment from letters to
+        plain numbers (1/2/3...), reasoning that it should match what
+        `detected_id` looks like when read successfully. Wrong -- caught
+        by the user immediately: auto-assignment (no real id known, a
+        manual add or an accept with no confident read) and a genuinely
+        detected id need to stay visually distinct, or a made-up
+        auto-assigned number could collide with, or be mistaken for, a
+        real one. Reverted back to `_next_free_id` (letters, rolling
+        over to "AA"/"AB"/... past 26 rather than raising
+        `StopIteration`) as the auto-assignment fallback, scoped per
+        type same as above; plain numbers are reserved for an id
+        `_accept_proposal` is actually confident was read off the
+        marker itself (`Proposal.detected_id`), passed straight through
+        as `id_` and never touching auto-assignment at all.
+      - `_accept_proposal` now actually USES `detected_id` (it was only
+        being logged before, never applied) -- an accepted proposal's
+        entity id prefers the detected number over auto-assignment,
+        falling back on a collision (scoped per type, same bug fixed
+        in two places: this collision pre-check, and the "Change ID"
+        popover's own check, which still enforced the OLD shared-per-
+        group rule after the auto-assignment change above and rejected
+        valid renames across types). 4 new regression tests
+        (`tests/test_app_accept_proposal.py`).
+      - `detected_id` is now shown, not just logged: the proposal
+        popover's heading (", id #8") and the pending-proposal's own
+        on-map label (`? #8 G8 5:4`) both show it while there's still a
+        screenshot up to check it against by eye.
+
+## Windows build (packaging/windows) -- real progress, not yet a clean pass
+
+Booted the actual dockur/windows build VM and drove it live (VNC) to find
+out what's really failing, rather than guessing from the README's own
+"UNTESTED end to end" note. Three real, separate bugs found and fixed,
+each confirmed live against the real VM, not just read off a diff:
+
+- [x] The build watcher was never actually installed at all, despite
+      `install_progress.log` claiming every provisioning step succeeded.
+      `C:\OEM` (dockur's `/oem` staging dir) doesn't reliably persist past
+      Windows Setup finishing -- exactly what the (already-uncommitted,
+      now committed) `install.bat`/`watch_build.bat` fix diagnosed, just
+      never verified against a real run before now. A 2-day-old
+      `BUILD_REQUEST` had been sitting unclaimed the whole time. Manually
+      re-applied the fix's logic live once (copied the corrected files to
+      `C:\FenigmaBuild`, registered the Startup-folder entry) and
+      confirmed on a full container restart that the watcher now
+      auto-starts on login and picks up a pending request with zero
+      manual intervention -- the actual fix, not just my live patch, is
+      what's doing that.
+- [x] `pip install pytesseract` fails outright: MSYS2's mingw64 Python
+      enforces PEP 668 ("externally-managed-environment"), which
+      `install.bat` never accounted for. Needs `--break-system-packages`.
+- [x] `import fenigma.app` fails with `ModuleNotFoundError: No module
+      named 'cv2'` even after `pacman -S mingw-w64-x86_64-opencv`
+      succeeds -- that package is the C++ library only. The actual
+      Python bindings are a SEPARATE package, `mingw-w64-x86_64-
+      python-opencv`, that `install.bat`'s dependency list simply never
+      included. (`pip install opencv-python-headless` as a fallback
+      doesn't work either and shouldn't be relied on: MSYS2's mingw64
+      Python uses a different ABI than PyPI's Windows wheels
+      -- `cp314-mingw_x86_64_msvcrt_gnu` vs `win_amd64` -- so pip can
+      never use a prebuilt wheel there, only build from source, which
+      then needs a full separate native toolchain -ninja/cmake/gcc- this
+      VM doesn't have either.)
+
+  All three are one-line fixes once known. `install.bat`'s pacman package
+  list and pip install line need these applied for a from-scratch VM to
+  provision correctly (currently they're only proven fixed live on this
+  session's VM, not yet folded back into the committed `install.bat` --
+  do that before relying on a fresh `./build_windows.sh` run from
+  scratch).
+
+  With all three fixed, `import fenigma.app` succeeds and a real build
+  attempt got all the way through source copy, sanity check, dist-tree
+  assembly, and WiX harvest+compile (`candle.exe`) -- further than this
+  pipeline has ever gotten. Two more issues surfaced right at the finish
+  line:
+  - [x] `product.wxs`'s `Version` needs strict WiX `x.x.x.x` numeric
+        form -- a `0.1.0-test` version string (my own test invocation,
+        not `build_windows.sh`'s real default) fails `candle.exe` with
+        CNDL0108/CNDL0010. Not a real bug, just don't pass a version with
+        a suffix.
+  - [x] `light.exe` (final MSI linking) did not finish within 15 minutes
+        on a first retry (4 CPU / 8GB RAM VM) before the RAM-conscious
+        auto-shutdown killed it -- turned out to be genuinely just slow
+        (process was active, 343MB working set, not hung on a dialog),
+        not a real bug: retried with a 40-minute budget and it finished
+        `light.exe` itself in a few more minutes.
+  - [x] ...and then failed for a REAL reason right at the very end:
+        `light.exe`'s ICE80 validation rejected essentially every
+        harvested file -- "This 32BitComponent ... uses 64BitDirectory".
+        `product.wxs`'s own `INSTALLFOLDER` is correctly under
+        `ProgramFiles64Folder` (a 64-bit mingw64 toolchain is what's
+        actually being packaged), but nothing was making the components
+        agree -- a real, on-disk mismatch, not a transient VM issue.
+        First fix attempt (`-platform x64` on `heat.exe`'s harvest) was
+        WRONG -- re-verified live, identical ICE80 failures afterward
+        (confirmed the corrected `build.bat` had actually reached the VM
+        this time, ruling out a stale-copy repeat of the earlier watcher
+        bug). WiX v3's `heat.exe -platform` only affects registry-key
+        harvesting, it never stamps `Win64="yes"` on components. Real
+        fix: `-arch x64` on `candle.exe` (the COMPILE step, not the
+        harvest step) -- sets the default Win64/Platform for every
+        component compiled from either source file, hand-authored
+        (`product.wxs`) or harvested (`files.wxs`) alike, the standard
+        WiX v3 way to make a whole package consistently 64-bit. Kept the
+        harmless-but-insufficient `-platform x64` on `heat.exe` too.
+
+        **CONFIRMED live**, third attempt: `build_errorlevel=0`,
+        `BUILD_DONE`, and a real 958MB `FEnigma-0.1.0.msi` written to
+        `Z:\dist` -- the first ever fully successful build this pipeline
+        has produced. Copied to `dist-windows/FEnigma-0.1.0.msi` in the
+        repo root (gitignored, same as `build_windows.sh` itself would
+        do). NOT yet installed/launched on a real Windows machine to
+        confirm the app actually runs (see the "Not tested against a
+        real GTK4/libadwaita Windows install at all" line in this repo's
+        own `packaging/windows/README.md` -- still true, packaging
+        succeeding is not the same claim as the app working once
+        installed).
+
+        Follow-up, now that a clean build exists to measure against:
+        `light.exe` alone took ~15-18 minutes even with ICE80 fixed --
+        revisit the ~1GB+ bulk-copied mingw64 dist tree (README's own
+        "not lean" note) as a real perf issue, not just a packaging-
+        correctness one.
+
+## OCR: new fire-support-request grammar gaps (from real user-pasted messages)
+
+- [x] A "taking fire" report's reporting unit ("Infantry#11 taking
+      fire!...") was being added as a hostile Target, not a friendly
+      Ally -- see the id-scheme entry above for the "no Friendly/Hostile
+      prefix word exists in this grammar" root cause and the fix
+      (`_TAKING_FIRE_RE`, `force_ally`, and splitting the shell/deadline
+      into a synthetic StrikeRequest even for the no-offset "on our
+      position" case, which previously kept them on the entity itself --
+      fine when it was wrongly a Target, silently lost once correctly an
+      Ally, since Ally tuples carry no shell/deadline fields at all). 4
+      existing tests updated, all still passing plus the rest of the
+      suite (51 total).
+
+- [ ] A multi-shell sequential request ("Requesting TEAR Shell first,
+      then HE Shell, at bearing...") only captures the FIRST shell
+      (TEAR) into the structured `shell` field -- "then HE Shell" isn't
+      parsed into anything. Less urgent than it first looked though: the
+      full original message text (both shells, in order) is already
+      preserved as-is and shown to the player via the coord dialog's
+      description view (`Location.desc_raw`, set from the same `raw`
+      every merged target/ally carries) -- nothing is silently LOST, it's
+      just not machine-parsed into a queryable second-shell field. Real
+      scope question before building that: does the board/firing-panel
+      data model even have a place to put a second shell for one strike
+      request today, or does this need a new field/shape entirely --
+      worth confirming it's actually wanted (vs. "read the raw text
+      yourself, it's right there") before spending the design effort.
+- [x] "Answer by 10:30:00" turned out to be one bug, not two. The
+      phrasing itself was never the problem -- `_TAKING_FIRE_TIME_RE`
+      already matches any `before|by <time>`, "Answer BY 10:30:00"
+      included. The REAL bug: a same-message "Important: ..." follow-up
+      line was misread as a brand new named entity header (the
+      last-resort bare-`<name>:` fallback rule matched "Important:"
+      itself with nothing excluding common prose lead-ins), creating a
+      bogus `Target#Important` that stole "Answer by 10:30:00" into ITS
+      own `requested_time` instead of the real report's. Fixed with a
+      blocklist (`_BARE_NAME_HEADER_BLOCKLIST`: important/note/warning/
+      attention/caution/alert/reminder/priority) on that fallback rule --
+      once the phantom split stopped happening, the deadline resolved
+      onto the right entry with no separate fix needed. New regression
+      test, confirmed against the user's real pasted message (with an
+      assumed `Infantry#N taking fire!` header line prepended, since
+      their paste seems to have been cropped before it).
+
+- [x] "\<Type\>#\<id\> Destroyed" kill-feed parsing already exists and
+      already marks the matching Target dead (`parse_destroyed`,
+      `_merge_targets`'s own destroyed-handling block in app.py) --
+      confirmed working end-to-end against a real 9-entry kill-feed
+      paste, including multi-word types ("Enemy Mechanized Infantry#2
+      Destroyed" correctly resolved to INFANTRY_MECHANIZED). This was
+      already-existing, working functionality, not something needing to
+      be built.
+      One real gap found in the same test: "Enemy Field Gun#1 Destroyed"
+      silently dropped. Two bugs stacked, both fixed:
+      - [x] "Field Gun" is just the game's own alt name for plain
+            Artillery (confirmed by the user directly) -- not a missing
+            unit type needing a new enum member/icon after all. Added to
+            `_TYPE_WORD_ALIASES` next to AmmoCache/CoastalBattery.
+      - [x] Even with that alias, it still didn't resolve: `_ALLY_PREFIX_RE`
+            only ever stripped a leading "Friendly"/"Hostile" word, never
+            "Enemy" -- so `squash_multiword_ids`'s "EnemyFieldGun#1"
+            token got alias-looked-up and fuzzy-matched as a WHOLE
+            ("EnemyFieldGun" vs "Artillery", nowhere close), not just its
+            "FieldGun" part. "Enemy Mechanized Infantry#2" only ever
+            worked by fuzzy-match ACCIDENT (a long, distinctive type
+            string still clears the ratio threshold with "Enemy" stuck
+            to the front; a short, unrelated one like Artillery doesn't).
+            `_ALLY_PREFIX_RE` now strips "Enemy" too, with a lookahead
+            requiring something after it -- a BARE "Enemy#N" is
+            `TargetType.ENEMY` itself (its own value IS "Enemy"),
+            stripping unconditionally would've left an empty type_word
+            and broken every ad-hoc "Enemy#N Destroyed" report instead.
+      3 new regression tests, all passing (54 total).
