Summary

A non-finite attribute could serialize as {"Float":null}, leaving a saved project that could not reopen. Human-readable output now writes NaN and infinity using the existing Null value encoding. Output preparation reports one counted notice with affected dataset locations, including values retained in layer design and archived feature snapshots.

Interactive numeric edits, template defaults and subtype defaults reject non-finite input before mutation; Calculate Field counts conversion to null. Typed source readers retain non-finite numbers until output can report the loss, and preserve fractional or oversized source numbers instead of truncating or clamping Integer fields. Finite values keep their encoding, and binary serialization retains native float values. Save, recovery, browser download and embedded-project output use the shared report; new interface notices retain translation arguments.

GeoPackage edits preserve unchanged NaNs when another field changes. Row fingerprints distinguish non-finite source cells from null, so clearing them is saved; finite fingerprints remain compatible. Whole-layer and streamed GeoJSON/GeoPackage exports count values written as null. Set Value preserves finite coercion behavior while reporting fractions, clamping and integer precision loss. Create Feature reports those losses through the same diagnostics.

Project output refuses current non-finite values in editable source layers before writing anything. Keeping their original baseline hashes while substituting Null would manufacture pending source edits after reopening. The refusal names the layer and count; users can explicitly clear or replace those values first. This intentionally blocks both explicit saves and recovery copies while such current values remain in a source-edit layer, including a read-only source. Existing project/recovery files and live source values remain unchanged on refusal. Fully lossless persistence of these values with source-edit identity needs separate format or reload-design coordination. Ordinary imported data still uses the counted Null substitution. No new saved-value encoding is introduced.

Testing

Passed cargo xtask ci (5,373 passed, 0 failed, 22 ignored), the rustgis-web WebAssembly build and all pre-commit hooks on 51d0a22c.

Focused validation passed the unchanged-NaN GeoPackage regression, chunked export regression, nine map-source tests and all fourteen project-save tests across the recorded focused runs. Regressions cover clean output without loss notices, non-finite edit and template refusal without mutation, integer parsing without invented values, counted source values, translated output notices, saved and recovered project reopen, and non-finite template defaults and archived attributes when current rows are finite. Additional regressions cover existing numeric defaults, explicit null clears without a loss notice, source NaN/infinity clears, unrelated GeoPackage edits, and clean/lossy whole and streamed exports. The latest focused run passed seven MapInfo tests and all fourteen project-save tests. The source-baseline regression checks refusal without modifying an existing destination, unchanged live rows and intentional clears surviving reopen as pending source edits. Rendered and inspected the actual save, export, feature-creation and editable-source refusal notices with ui_shot.

Summary by CodeRabbit

• Bug Fixes
  • Invalid numeric values such as NaN and infinity are rejected when entered as feature attributes or template defaults, with an error identifying the affected field.
  • Imported numeric values are handled more consistently across supported data formats.
  • Replacing a loaded non-finite value with null is now recognized as a data change.
  • Saving is prevented when non-finite values in editable layers would create source edits.
• Improvements
  • Saving projects reports when non-finite numbers are converted to null, including affected locations where available.
  • GeoJSON and GeoPackage exports report how many non-finite numbers were written as null.
  • Numeric edits notify you when values are truncated, clamped, or lose precision.

Walkthrough

Source parsing preserves non-finite numeric values, while interactive edits validate them separately. Human-readable serialization writes non-finite floats as null. Durable-output preparation and supported exports count affected values and report those counts through notices.

Changes: Non-finite value handling

Layer / File(s)	Summary
Parsing and serialization crates/data/src/value.rs, crates/data/src/gml.rs, crates/data/src/io.rs, crates/data/src/mapinfo.rs, crates/data/src/source/*, crates/engine/src/cmd/edit.rs	Value::parse_source preserves successfully parsed non-finite numeric source values. Interactive parsing maps non-finite numeric input to null. Human-readable serialization writes non-finite floats as null. Import paths use source parsing.
Interactive input validation crates/engine/src/cmd/design.rs, crates/engine/src/cmd/edit.rs, crates/engine/tests/project_save.rs	Feature creation and template defaults reject non-finite numeric inputs. set_value rejects non-finite numeric strings and reports specified lossy coercions. Tests cover input rejection, defaults, and coercion notices.
Durable-output counts and notices crates/data/src/lib.rs, crates/map/src/design.rs, crates/engine/src/durable.rs, crates/engine/src/project.rs, crates/engine/src/notice_text.rs, apps/rustgis-web/src/web.rs, crates/ui-egui/src/lib.rs, crates/engine/tests/project_save.rs	Dataset and design values contribute to durable-output counts. Reports aggregate counts and affected locations, then publish typed notices through sessions. Tests cover save, recovery output, imports, and reopening.
Export counts and stored-value tracking crates/data/src/export.rs, crates/data/src/export/tests.rs, crates/data/src/source/gpkg/edit.rs, crates/engine/src/cmd/share.rs, crates/engine/tests/project_save.rs, crates/map/src/source.rs	GeoJSON and GeoPackage export results include counts of numeric values written as null. Export paths report positive counts. GeoPackage editing treats two NaN values as unchanged, and row hashing distinguishes non-finite attributes from null.

Bug (pre-existing, but the new doc comment above is wrong about it): Integer text of NaN or infinity is silently converted.

The doc comment says text a number field can't hold, including non-finite values, is Null. That holds for Double only. Here "NaN" parses as Ok(NaN), and NaN as i64 is 0. "inf" and "1e400" saturate to i64::MAX. parse_source routes non-Double types here too, so GPKG, MIF, CSV and GML readers hit it.

Suggested fix, which also matches the doc comment:

Suggested change

	t.parse::<i64>().map(Value::Int).or_else(|_| t.parse::<f64>().map(|f| Value::Int(f as i64))).unwrap_or(Value::Null)
	FieldType::Integer => t.parse::<i64>().map(Value::Int).or_else(|_| t.parse::<f64>().ok().filter(|f| f.is_finite()).map(|f| Value::Int(f as i64)).ok_or(())).unwrap_or(Value::Null),

Add Value::parse("NaN"/"inf"/"1e400", Integer) == Null to the value tests. The test at line 432 already pins the finite cases.

[Mavrick-F]

Fixed in 5f024a5. Integer parsing no longer turns non-finite text into zero or a saturated integer. Source parsing retains those values until counted output; interactive parsing produces null, with command ingress rejecting non-finite numeric input. The parser regression covers both numeric field types. Focused tests, full native CI, WebAssembly and hooks passed.

Code review

Bugs

• Non-finite Doubles reach the .dbf writer as text (crates/data/src/io.rs:2597, not in the diff, so no inline comment). dbf_number returns Some(NaN) and Some(inf). The writer then emits NaN/inf into numeric fields. The "rounded" count is wrong for NaN because NaN != NaN, and infinity is counted as nothing. Newly reachable because parse_source now keeps non-finite Doubles from MIF, GML and text fields. Fix: add x.is_finite() && to the filter, so these values go to the existing "left empty" notice, and add a regression test. Confidence: high on the code path, medium on the exact bytes the dBase crate writes.
• Template defaults accept NaN, then add_feature refuses (crates/engine/src/cmd/design.rs:1871, not in the diff). edit.template stores coerce(...), which keeps "NaN" as a Double. Later, add_feature fails with "requires a finite number" whenever that attribute isn't supplied. This breaks the PR's own rule that interactive edits refuse non-finite input at ingress. Fix: refuse like set_value does. Confidence: medium-high.
• Integer text of NaN or infinity is silently converted (crates/data/src/value.rs:131, posted inline). Value::parse gives 0 for "NaN" and i64::MAX for "inf"/"1e400". The doc comment added in this PR says these become Null, which is true only for Double. Pre-existing, but reachable through parse_source. Confidence: high.

Security

• None found in the changed code.

Performance

• None significant. The save-time scans are linear and small next to serialization.

Quality

• Export gap in "Never silent": the GeoJSON attribute writer uses Value::to_json, which writes non-finite values as null (crates/data/src/io.rs:1352). No notice is given, and the new report covers only project and output preparation. The PR does not claim exports are covered, so this is a scope question. Confidence: medium.
• Nits, for the release quality pass:
  • The Dataset::unsaved_numbers doc says "None" but the function returns 0.
  • The Value Serialize doc wording ("which a number can't be read from") is hard to follow.
  • coerce_cut guards with ty == Double, while non_finite_input checks is_numeric(). The Integer case is handled by convert, but the asymmetry is confusing.
  • "...".to_string().into() in durable.rs could be written more simply.

AGENTS.md

• No unwrap, expect, panic or unsafe in new non-test code. Tests cover both clean and lossy input. Translatable notices use NoticeText. No new platform-specific APIs, so wasm is unaffected.
• I checked for double counting between Map and Layer prepare, and between Project and Table. Neither occurs.

I did not re-raise concerns from earlier reviews, because there were none on this PR.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Report::notify and the free notify build different notice text.

Report::notify sends each notice without the "Prepared output: {message}" wrapper. The free function notify adds that wrapper. web.rs and save_download use Report::notify. Other paths use the free function. The same loss reads differently by save path. The PR screenshot shows the "Prepared output:" prefix. Make the two paths agree. For example, have Report::notify apply the wrapper and have the free function delegate to it.

The new regression test asserts the key starts with "{count} attribute value(s)". That assertion would fail if the wrapper were added. Update the test with the fix.

Proposed fix

     pub fn notify(&self, session: &mut crate::Session) {
         for text in self.notice_texts() {
-            session.notify_text(text, false);
+            session.notify_text(crate::notice_text::NoticeText::format("Prepared output: {message}", [("message", text)]), false);
         }
     }

Fixed in 5f024a5. edit.template validates numeric defaults before replacing the existing template. The regression rejects NaN, infinity and overflow text and verifies the previous finite default is unchanged; native/imported hostile defaults remain covered by the counted save/recovery regression. All local gates passed.

[Mavrick-F]

The template and integer parsing issues are fixed in 5f024a5, with 11 data tests, nine project-save tests and full CI (5,364 passed), WebAssembly and hooks passing.

The DBF finding does not occur: Value::as_f64 filters non-finite Float and Text values before dbf_number sees them. The existing shapefile_notes_cover_incompatible_and_rounded_cells regression writes and reopens NaN/infinity as null and checks the counted “left empty” notice; it passed in full CI.

GeoJSON export notices are a pre-existing gap outside this saved-project lifecycle fix; this PR does not claim to cover them. The documentation wording, coercion symmetry and conversion-style nits are left for the release quality pass.

[Mavrick-F]

The numeric-template ingress finding is fixed in 5f024a5; rejected defaults leave the existing template intact. Focused regressions, full native CI, WebAssembly and hooks passed.

The outside-diff notice-prefix finding preserves existing behavior: browser download and embedded output previously sent report.notices() directly, while desktop preparation added “Prepared output:”. Both retain the count and location. Uniform prefix wording and the helper-reuse refactor are left for the release quality pass.

[github-actions]

Possible silent write-back loss for live sources (confidence ~0.6).

Non-finite floats now serialize exactly like Null, and crates/map/src/source.rs:257 (row_hash) hashes the row's attributes through this same Serialize. Versions::changes (source.rs:359) decides which loaded rows are written back to PostGIS/MySQL by comparing those hashes. So a loaded row whose double cell goes from NaN (or ±inf) to empty/Null has the same hash as before and is not reported as updated. The edit is dropped without a notice. NaN↔inf changes collide the same way.

Before this change the two encodings differed ({"Float":null} vs "Null"), so the collision is new.

Suggested direction: give row_hash its own encoding for non-finite numbers (e.g. hash to_bits() for them), and add a regression test where a NaN cell is cleared and changes() reports the update.

[Mavrick-F]

Fixed in 6944869. Row hashes now distinguish each non-finite float from Null without changing the finite-value hash. The regression checks that clearing NaN and either infinity produces a source-row update.

[github-actions]

Infinity is reported as "isn't a number" (confidence ~0.5, accuracy of the notice).

For a Double field, ±inf takes this branch and gets Cut::NotANumber. Cuts::notices (line 166) then says 'field' is null for N results that aren't numbers, which is wrong for infinities. Calculate Field can produce 1/0, so a user will see that wording for a value that is a number.

A separate variant (for example Cut::NotFinite, worded "aren't finite numbers") would keep the notice accurate. The Cut::NotANumber doc at line 130 should be updated to match.

[Mavrick-F]

The conversion already reports the null count and field. The more precise “not finite” wording is left for the release quality pass.

[github-actions]

GeoPackage export still nulls non-finite numbers silently (pre-existing, but on a line this PR edits).

(Value::Float(_), _) => Sql::Null drops NaN/infinity with no notice. The project save path now counts these, but this writer doesn't. That breaks the "never silent" rule for writers. This PR widens the set of values that can reach this arm: an Integer field can now hold a non-finite Float after a source read (see parse_source in value.rs).

Suggest counting the nulled values and returning a notice through the export's report, following the same pattern as Dataset::unsaved_numbers. It can be a follow-up, but the PR description says output losses are counted.

[Mavrick-F]

Fixed in 6944869. GeoPackage and GeoJSON exports now count values written as null and publish a translated notice with the count and output path. The regression covers clean and lossy resident and streamed exports.

[github-actions]

Pre-existing silent loss on a line this PR touches.

Value::parse here truncates fractions and clamps out-of-range integers without a notice. set_value with "2.7" in a Long field stores 2, and "1e30" stores i64::MAX. Non-numeric text in a number field becomes Null, also silently. coerce_cut already reports these cases (Cut::Fraction, Cut::Range), so the two paths disagree.

Since the arm above is now the non-finite guard, this is a good place to route the string case through coerce_cut and report its cuts. Not a regression, but "existing silent losses are bugs".

[Mavrick-F]

Fixed in 6944869. Set Value preserves its existing conversion behavior and now reports fractional truncation, range clamping, precision loss and invalid numeric text, with the layer, field and row. Explicit null input and exact numeric input stay quiet; the regression checks both.

[github-actions]

Code review

Inline comments are posted on four lines. I could not compile or run the tests here, so the findings below come from reading the code.

Bugs

• Write-back of cleared NaN/±inf cells can be silently skipped (confidence ~0.6). Value's new Serialize writes non-finite floats as Null, so row_hash (crates/map/src/source.rs:257) gives NaN/inf and Null the same hash. Versions::changes then misses the edit when a live PostGIS/MySQL row changes that way. Inline on value.rs:62.
• Infinity is described as "isn't a number" (confidence ~0.5). coerce_cut maps ±inf in Double fields to Cut::NotANumber, so Calculate Field's notice is inaccurate for infinities. Inline on edit.rs:175.
• GeoPackage export still nulls non-finite numbers without a notice (confidence ~0.7, pre-existing). sql_value at gpkg.rs:1149 is on a line this PR edits, and the PR widens which values reach it. Inline on gpkg.rs:1149.
• set_value silently truncates and clamps text (confidence ~0.8, pre-existing). Value::parse turns "2.7" in a Long field into 2 and "1e30" into i64::MAX with no notice, while coerce_cut reports the same cases. Inline on edit.rs:298.
• Integer fields can now hold non-finite Float values after a source read (confidence ~0.3, design question). parse_source keeps them until save. Consumers such as the GeoPackage writer and the Update tool's converted then null them silently. Not raised inline.

Security

• None found. The new notice text keeps dataset names as literal data.

Performance

• An extra O(n) pass over features on every save, through unsaved_numbers. This is acceptable next to the serialization that already runs. No issues found.

Quality (nits, left for the release quality pass)

• The doc on Dataset::unsaved_numbers (crates/data/src/lib.rs:333) says "None for a window", but the function returns usize and yields 0.
• Layer::prepare counts the same datasets that Map::prepare already counts. It is currently unreachable, but it would double-count if someone later adds a Layer child.
• The is_human_readable branch has no binary serializer to protect in this codebase, so the PR's "binary keeps native floats" claim is untested.

AGENTS.md

• No unwrap/expect/panic was added to non-test code.
• Loss notices carry a count, use NoticeText for translation, and have both lossy and clean tests.
• Known gaps: the set_value silent truncation and the GeoPackage writer's silent null (both above).

I left 3 earlier concerns alone. Two (NaN template defaults and Integer NaN parsing) are addressed by this diff. The set_value duplication was already answered as left for the quality pass.

[github-actions]

Silent loss in edit.addFeature (confidence ~0.6). coerce is the uncounted conversion: non-numeric text in a number field becomes Null, and "2.7" in an Integer field is stored as 2, with no notice. set_value now reports these same cases through coerce_cut, but this call path doesn't, so the two commands disagree. Since this line is changed in this PR, it's a reasonable place to route it through coerce_cut and emit the same per-field notices as set_value. Refusing non-finite input here is already correct.

[Mavrick-F]

Fixed in 51d0a22. Create Feature now shares Set Value’s loss diagnostics and reports the field, row and count after a successful edit. The regression checks fraction truncation, range clamping and invalid numeric text, plus quiet explicit-null and exact-number input. The actual creation notice was rendered and inspected.

[github-actions]

Pre-existing silent truncation on the source-reader path this PR now calls (confidence ~0.5). parse_source only keeps non-finite numbers. Every other Integer text still goes through Self::parse, which truncates fractions ("2.7" → 2) and clamps out-of-range values ("1e30" → i64::MAX) without a notice. The GeoPackage, MapInfo, GML, CSV and parquet-adjacent readers that this PR switched to parse_source inherit that. Not a regression, but the PR's "never silent" rule covers readers. Either report these cuts from the readers, or leave a note tying this to a follow-up.

[Mavrick-F]

Fixed in 51d0a22. Source parsing keeps numeric text that is not an exact i64 as a Float, matching the existing handling of native real source cells. It preserves 2.7 and 1e30 instead of truncating or clamping them. Exact integer text remains Int. The MapInfo regression reads an Integer-declared field containing both values and a clean integer, and verifies that none is discarded.

Code review

Most earlier review concerns are fixed in this head. I checked each against the current code and did not repeat them. Two new findings are posted inline. One earlier concern remains and I left it alone.

Bugs

• No new bugs found. The paths I checked hold up: the Value serialization order matches the enum, numbers_written_as_null agrees with the GeoPackage sql_value arms, count_numbers is not double-counted (Map::prepare doesn't call Layer::prepare), and the non-streamed GeoPackage and GeoJSON exports report left_out as 0, so the count matches what is written. (confidence: high)

Security

• None found. (confidence: high)

Performance

• The save path adds a full pass over every dataset and archive (unsaved_numbers), and GeoPackage chunk export re-parses every text value in numeric fields. Both are linear and small, so this is minor. (confidence: medium)

Quality

• Duplicated counting in Map::prepare (durable.rs ~807–810) and Layer::prepare (~829–830). Left for the release quality pass. (confidence: medium)
• Dataset::unsaved_numbers doc (lib.rs ~334) says "None for a window", but the function returns usize and gives 0. The coerce_cut doc (edit.rs ~172–173) doesn't mention the new non-finite Double branch. Left for the release quality pass. (confidence: high)

Silent loss

• Inline, edit.rs:62: edit.addFeature uses the uncounted coerce, so non-numeric text or a fraction written into a number field is lost without a notice, while set_value reports those cases. (confidence: ~0.6)
• Inline, value.rs:88: parse_source only keeps non-finite numbers. Integer fraction truncation and clamping still happen silently on the reader lines this PR changed. This is pre-existing. (confidence: ~0.5)

AGENTS.md

• No unwrap, expect or unsafe in new non-test code. Notices go through notify_text/NoticeText, with counts and locations. Each new notice has a clean-input test. The ribbon and i18n rules don't apply to this diff. (confidence: high)

Prior review threads

• Ten threads already exist on this PR. Nine are addressed in this head and I did not re-raise them. The coerce_cut infinity wording thread (edit.rs ~175, "isn't a number" for ±inf) is still present, unanswered, and I left it alone.

[Mavrick-F]

The review batch is fixed in 6944869: non-finite values have distinct source-row hashes; unchanged GeoPackage NaNs survive unrelated edits; whole-layer and streamed GeoJSON/GeoPackage exports report null conversions; subtype defaults reject non-finite input before mutation; and Set Value reports lossy finite conversions. Source readers continue to retain non-finite source values until a counted output boundary.

Validation: full native CI passed (5,370 tests, 0 failures, 22 ignored), together with the WebAssembly build and hooks. Focused regressions cover the source update, GeoPackage edit, clean/lossy exports and subtype cases.

The infinity notice wording, documentation wording, helper refactoring and optional serialization tests are left for the release quality pass.

Prevent project output from creating source edits.

When an editable layer contains an unchanged non-finite attribute, project output writes Null but retains the original row hash. After reopen, the row can appear as a pending update. Saving edits can then replace the source attribute with SQL NULL, even though the user did not clear it.

[Mavrick-F]

Fixed in 51d0a22. Controlled project output now refuses non-finite current rows in editable source layers, with the count, layer name and action needed. This prevents Null substitution from manufacturing source edits after reopen while keeping the existing saved-value encoding. The regression demonstrates the raw-serialization mismatch, then checks Save and recovery refusal, preserved destination bytes and unchanged live rows/baselines. Explicitly clearing the cell remains a real pending update after save and reopen.

Create Feature now reports lossy numeric coercion through the same diagnostics as Set Value. Source readers retain fractional and oversized numbers instead of truncating or clamping them into Integer fields.

Validation: seven MapInfo tests and all fourteen project-save tests passed; full native CI passed (5,373 tests, 0 failures, 22 ignored), with the WebAssembly build and hooks. Actual Create Feature and editable GeoPackage save-refusal screenshots were rendered, inspected and added to the PR.

The previously raised documentation wording and optional helper refactors remain for the release quality pass.

[github-actions]

Read-only source layers are refused too, and the advice doesn't fit them (confidence ~0.6).

Layer::edit_versions() (crates/map/src/lib.rs:319) returns Some for any PostGIS or GeoPackage edit layer, whether or not it is writable. So a read-only table that holds a NaN or infinity, which PostgreSQL float8 allows, makes every save fail: saved_text, recovery_text_with_report and save all go through prepared(). The message says to "explicitly clear or replace them first". For a read-only layer, clearing the value only changes the local copy, and it can't be written back, so the save still can't go through unless the layer is removed.

Suggest either keeping the refusal to writable layers and handling read-only ones separately, or naming the layer's read-only state in the message so the user knows the way out is removing it. A test with a writable: false layer would pin whichever choice is made.

[Mavrick-F]

The refusal deliberately covers layers that retain source-edit baselines. Clearing or replacing the local cell does allow project saving: the guard checks dataset.unsaved_numbers(), and that count becomes zero after the local edit. need_editable and apply_with do not require source write permission; the source’s writable flag controls writing edits back to the database/file. No source save is required to satisfy this guard, and the layer need not be removed. The proposed failure after a local clear therefore does not occur.

[github-actions]

The location list is cut at three datasets, and the notice doesn't say so (confidence ~0.4).

The total count covers every dataset, but number_places holds only three names, and the notice reads "affected datasets include {places}". A project with four or more affected datasets gets a notice that names three of them, with no sign that others were left out. The "never silent" rule asks that the output say where the losses are, and this drops part of that.

Suggest appending "and N more" when the list is cut, or tracking the number of omitted places and adding it to the notice. A test with four affected datasets would cover it.

[Mavrick-F]

The notice says “affected datasets include”, so the names are a bounded, non-exhaustive list. Its attribute-value count includes every affected dataset; no values are omitted from that count. Adding an explicit omitted-location count and an extra four-dataset wording assertion are left for the release quality pass.

Code review

The PR is broad and most of it holds up on inspection. Two findings are worth raising, both posted inline. I checked the rest of the diff and found no bugs in it. The summary is below.

Bugs

• Medium confidence (~0.6): the project save refusal also blocks read-only source layers. Layer::edit_versions() returns Some for any PostGIS or GeoPackage edit layer, whatever its writable flag. A read-only table holding a NaN or infinity makes every save, recovery and output fail. The "clear it first" advice does not work for a read-only layer. (crates/engine/src/durable.rs:291)

Security

• None found. The new paths only add counts and notices. Nothing new reaches a file, network or command boundary.

Performance

• None found. The extra passes over attributes run during save, which is already O(n).

Quality

• Low confidence (~0.4): the counted notice lists at most three affected datasets and does not say others were left out. This falls under the never-silent rule, so it is posted rather than deferred. (crates/engine/src/durable.rs:309)

AGENTS.md

• Checked the no-unwrap/expect rule in non-test code, the never-silent rule for each writer and the counted export extension list, and the notice translation path. No violations found.
• The Layer::prepare count is also reached through Map::prepare, which is not a double count today, because nothing prepares a Layer directly. It is a latent hazard only, and I did not post it.

Already raised, left alone

• I left 10 earlier concerns alone because the existing threads already cover them. Most are fixed in the PR, and the open ones are wording points that the author has left for the release quality pass.

The size figures above are in KB and rounded. The stats file reports bytes, so these rows are approximate.

[Mavrick-F]

The read-only scenario does not prevent a project save after an explicit local clear: the guard depends on the current dataset’s non-finite count, which becomes zero. Local editing does not check source write permission; writing the local change back to a read-only source remains a separate refusal.

The numeric loss count covers every dataset. “Affected datasets include” introduces bounded example locations. The optional explicit omitted-location count and additional wording test are left for the release quality pass.

[Mavrick-F]

The inability to save or recover this state is intentional and is now stated explicitly in the PR description. The originating task permits “save refuses with a clear error naming the layer/field” for non-finite values from other sources, and explicitly excludes inventing a new NaN encoding because that requires format coordination.

This guard keeps the live source values and baselines unchanged and refuses before replacing a project or recovery file. It prevents the manufactured source edit identified in the previous review. Explicitly clearing a value is an available user choice, not an automatic mutation. It does not require writing that choice back to the source.

Saving and reopening these exact non-finite values while keeping editable-source identity would need a lossless representation or a coordinated source-reload design. That broader capability is outside this task’s agreed format boundary. I am retaining the tested explicit refusal instead of weakening the guard or silently changing source-edit semantics.

The optional temporary-file cleanup guard is left for the release quality pass.
