* avoid undefined behavior from UNREACHABLE on reachable code paths
UNREACHABLE expands to __assume(false) / __builtin_unreachable() in
release builds, which is undefined behavior if the code is ever actually
reached. Many UNREACHABLE sites only guard against unexpected-but-
possible runtime states (values from tables, mission/save files, network
packets, scripting, or user input), so reaching them should degrade
gracefully rather than invoke UB.
Replace UNREACHABLE with Assertion(false, ...) at all such sites. It
still pops an error in debug builds, but in release it is a harmless
no-op that simply falls through to the following code. Sites that are
genuinely unreachable by local invariants (e.g. a switch over a bounded
random number) are left as UNREACHABLE.
A few converted sites had no safe fall-through -- an uninitialized read,
null dereference, or null call would have followed -- so they also get a
minimal recovery: initialize the value, guard the dereference, return
early, or skip the offending item.
Where the converted site was a simple guard of the form
if (x) { Assertion(false, ...); return; }
hoist the check onto the invariant instead:
Assertion(!x, ...);
if (x) { return; }
This states the expectation directly and shows the offending value in
the debug popup, while keeping the same graceful runtime degradation.

* addendum
After consultation with Lafiel, use UNREACHABLE in situations that are effectively impossible even if not provably impossible. UNREACHABLE = "this shouldn't ever happen"; Assertion = "if this ever happens, it's a coding error". Also fix a few other sites and change a couple to Warnings.

The SWH_SECONDARY case of the ship_bank setter was copy-pasted from the
primary case and still assigned primary_bank_* fields; it now assigns
the secondary_bank_* fields.

Two related fixes flagged by an audit of vm_vector_2_matrix_norm callers:
ParticleEffectAction: locals.direction defaulted to vmd_zero_vector,
which would trip vm_vector_2_matrix_norm's unit-length assertion (and
divide by zero in release) when an action program emitted a particle
effect without first running a Set Direction action. Default to
vmd_z_vector so the unset-direction path always feeds a unit vector.
matrix_h / Lua orientation type: the element indexer (m[1..9] = x)
wrote arbitrary floats straight into mtx.a1d[idx] and the resulting
non-orthonormal matrix could flow into obj->orient via the Orientation
virt-vars on object/modelinstance/subsystem, breaking downstream engine
code that assumes the basis vectors are unit length. getInterpolated
had the same problem by design (pure linear interp, no normalization).
Adds a fourth MatrixState, NeedsOrthonormalize, which the indexer
setter and getInterpolated use to flag their output. ValidateMatrix
and ValidateAngles now call vm_orthogonalize_matrix when they observe
that state, so any consumer that reads through GetMatrix/GetAngles
gets a valid orientation without each call site needing its own guard.
getInterpolated is also marked ADE_FUNC_DEPRECATED at FSO 26.0 in
favor of rotationalInterpolate; mods targeting older versions keep
the legacy linear blend (now safely orthonormalized on use).
* change to new fog system
* Fix fog conversion issues
* remove unused old neb values
* Update scripting API
* temporary old-value round trip
* Rewrite nebula fog with four explicit parameters
Replace the legacy `+Fog Near Mult` / `+Fog Far Mult` model — which
depended on fixed engine constants — with four parameters that map
directly to renderer behavior:
+Fog 1000m Visibility fraction of light surviving 1000m of fog
+Fog Near Distance meters from camera where fog begins
+Fog Skybox Clip Distance max render distance for the skybox in fog
+Fog Clip Distance max render distance for the scene in fog
The deferred-lighting fog shader, material system, model renderer,
object sort, and the Lua mission API all consume the new parameters
directly. The legacy `Neb2_fog_near_mult` / `Neb2_fog_far_mult`
globals are removed.
Mission parsing accepts either the legacy keys or the modern keys.
Legacy values are converted to the modern set at parse time, and a
per-mission flag (`Neb2_fog_use_legacy_values`) records which keys to
write back on save. The flag is cleared only when something actually
changes, so opening and OK'ing an unmodified legacy mission preserves
its on-disk format. Saving uses `optional_string_fred` to preserve
user comments through edit cycles.
FRED2 and QtFRED background editors both expose the four parameters
in place of the old multipliers, with friendly labels and tooltips.
Both editors validate input (visibility clamped to [0, 1]; near
distance must be > 0; skybox and scene clip distances may be 0 to
disable fog at that range) and use a snapshot-and-compare at close
time so that a no-op open-then-OK never spuriously rewrites a legacy
mission in the modern format.
FRED2's background dialog is also reorganized so that "Display bg
bitmaps in nebula", "Override nebula fog palette", the RGB row, and
the four fog parameters all sit inside the Nebula group box; the
"Old Nebula" group box is restored below it with its Pattern, Color,
Pitch, Bank, and Heading controls back inside the frame. The dialog
now overrides PreTranslateMessage so that the new fog tooltips —
and the previously broken "Save sun/bitmap angles in correct format"
tooltip — actually fire.
QtFRED's BackgroundEditor.ui adds four QDoubleSpinBox controls in
the existing nebula form layout, with per-field decimals chosen to
avoid scientific notation, and per-field min/max declaring the
validation rules. The QtFRED help page is updated to describe the
new fields.

* Clang Tidy

* Refine nebula fog rewrite
- Rename Neb2_fog_use_legacy_values to Neb2_fog_save_legacy_values
to reflect that the flag governs save format, not runtime
behavior.
- Decide both the save flag and the legacy-to-modern conversion
purely from whether the file contains modern fog keys, dropping
the prior heuristic based on required_fso_version. A mission
without modern keys (legacy- or retail-format) converts on load
and saves back in legacy format; missions with modern keys are
saved as modern.
- Snapshot the four fog values as floats at editor open and use
fl_equal for the no-change comparison in both FRED2 and QtFRED,
replacing the FRED2 CString comparison and the QtFRED strict
inequality.
- Document the on-disk invariant in missionsave: when not saving
legacy keys, the four modern keys must always be written (never
gated on "only if non-default"), since the parser uses their
presence to decide whether to run the conversion on next load.

* add wing display names
Adds display name capability for wings, matching the pattern and infrastructure of display names for ships. As in #7234, wing display names take precedence over ship display names, if both are provided; because if ship display names took precedence, a ship would have the same display name in every wave.
All the relevant display locations are handled, including the HUD, escort list, message box, and mission log. Lua API support is provided as well.
Adds full support for both FRED and QtFRED, including the always-save-display-names setting.
Addresses #7189 and the last request from #1730.
* add help text from #7234
Follow-up to #7251, which added `set-guard-range`
This PR exposes that value to scripting, so scripters do not have to use the more expensive `runSEXP` to use it.
The value is initialized as -1 (`max_guard_radius = -1.0f;` line 7913 in ship.cpp), hence the default value for the script is -1.
* use std::move() for local variables that are copied but not reused
Addresses ~140 Coverity "Variable copied when it could be moved"
defects across 74 files. Every std::move() targets a local variable
whose value is consumed by push_back, emplace, assignment, lambda
capture, or a function call and is never read again afterward.

The waypoint class stored its position in m_position separately from the game object's pos field, requiring callers to manually keep both in sync. Now get_pos() and set_pos() delegate to the object position when the game object exists, falling back to the parsed position only if the object does not exist.

* Tune ups for standalones
Fixes two warnings from building in standalone and also provide, also adds needed function to actually tell if game is in standalone mode.
* better fix for armor flags
1. Change `ai_profile_lookup` and `multi_xfer_lookup` to use `const char *`, since all the other lookup functions do
2. Remove several unneeded `const_cast`s, some of which are now made possible by the non-const `data()` overload in C++17
3. Change `campaign_link` to use `const char*`
4. Use better string management in `test::FSTestFixture::init_cmdline()`
The scripted `gr.drawOffscreenIndicator` was missing a critical `resetClip();` which meant it was using whatever the previous stack's clipping distance was, and thus not draw in the actual correct location.
This 1 line PR fixes that and the fix works as intended.
1. Modify `ship_get_subsys_for_submodel` to use the subsystem indexer. This changes the operation from O(n) to O(1) and also allows the function to work with turret gun barrels.
2. Add an `isValid` check to `ParticleSource::finishCreation` to prevent unknown state from being accessed if the source is not valid.
3. Tweak `EffectHostTurret` and make sure it works for fighter beams.
4. Prevent `createOnTurret` from running on submodels that are not turrets.
Testing in FotG exposed a bug that dates back to retail. During mission parsing, arrival and departure anchors were represented by indexes into `Parse_names`. After parsing, they were converted to ship indexes -- but only in FRED. Since some functions are shared between FRED and FS2, this can produce inconsistent results, which can be hard to detect since parse indexes and ship indexes are usually the same.
This refactors arrival and departure anchors to be represented by ship registry indexes in all cases. It also adds conversion functions for the benefit of FRED and QtFRED since those dialogs were designed with ship indexes in mind.

Just as special tokens are replaced in debriefings, replace them in command briefings and briefings as well.
Change `string_replace_tokens_with_keys` to `message_translate_tokens` (since it's the same thing) and add a `replaceContainers` script API function to complement `replaceVariables` and `replaceTokens`.
Also replace every category of token in `sexp_modify_variable` and add comments to places where token replacement might be expected but happens elsewhere.
All other display names are `SCP_string`, so make these `SCP_string` as well to be consistent and to allow arbitrary-length display names.
Also fix a few infelicities with German translation and the script API.
