F3: one documented substitution chain, and report what it chose and why
A font the document does not embed was replaced by whatever the caller happened to pick, and nothing told the user. `doc_info` said only `embedded: false`, which is why "my Chinese PDF shows nothing" has been a mystery rather than a sentence. `crates/fonts/src/fallback.rs` applies one chain, in a documented order, and returns what it chose with a reason: 1. embedded -> nothing substituted; 2. /BaseFont names a standard-14 face or a known alias (exact metrics); 3. craft-fonts holds that exact family; 4. /CIDSystemInfo /Ordering names a script we have a face for; 5. the ordering names a script we have no licensed face for -- report none, so nothing is drawn rather than the wrong glyphs; 6. otherwise the nearest of the fourteen by descriptor flags. It delegates to the existing per-script selectors instead of restating their order, so each keeps one source of truth. It answers the dictionary question only; "which face has a glyph for this character?" depends on the string being drawn and stays where the drawing happens. `doc_info` gains `substitute` and `substitution` per font. Both null means the document's own glyphs are shown; a null `substitute` with a reason means no face was available at all. That is Acrobat's Actual Font, minus the interface, which `parity/` now records as still missing. Two findings on the way: `Std14::from_base_font` matches loosely, so "SomeHouseSerif" resolved to Times by its name containing "serif". The face is a fair guess but reporting it as "names one of the standard 14" would have been untrue of a font nobody has heard of. `Std14::recognise` now says whether a name matched an alias or only a family hint, and the two report differently. `from_base_font` is unchanged. The generated table moved to `crates/fonts/src/std14_metrics.rs`, data alone, and the ATTRIBUTION entry and AGENTS.md 1.1 line follow it. F1 put the hash on a file holding both the table and the code reading it, so this commit's ordinary edits tripped the gate -- and a hash that churns on unrelated changes gets re-attested reflexively, which is the protection gone. Verified both directions after the split: editing std14.rs passes the gate, changing one width in std14_metrics.rs fails it. Every new test was watched failing first: removing the script step breaks the two unit tests and the doc_info integration test. Co-Authored-By: Claude <[email protected]>

//!
|
||||
//! Substitution used to be decided per caller and never written down: `edit` picked a craft face
|
||||
//! by the script of the text it was drawing, `Std14::from_base_font` matched Latin names, and the
|
||||
//! renderer did its own thing. Nothing told the *user* that the glyphs they are looking at are not
|
||||
//! the ones the document asked for, which is the difference between "PdfCraft shows nothing for my
|
||||
//! Chinese PDF" being a mystery and being a sentence.
|
||||
//!
|
||||
//! This module answers the *dictionary* question — "the document does not carry this program; what
|
||||
//! will stand in for it, and why?" — which is what inspection and reporting need. It deliberately
|
||||
//! does not answer the *text* question ("which face has a glyph for こ?"), because that depends on
|
||||
//! the string being drawn and is already handled where the drawing happens. It delegates to the
|
||||
//! existing per-script selectors rather than restating their order, so there is one source of
|
||||
//! truth for each.
|
||||
//!
|
||||
//! The chain is tried in order, and the first step that yields a face wins:
|
||||
//!
|
||||
//! 1. The document embeds the program. Nothing is substituted.
|
||||
//! 2. `/BaseFont` names one of the standard 14 (or a well-known alias such as Arial). Exact
|
||||
//! published metrics apply, so this is as close to right as a substitution gets.
|
||||
//! 3. craft-fonts holds that exact family. Never another family — see [`crate::embedding`].
|
||||
//! 4. The descendant font's `/CIDSystemInfo /Ordering` names a script, and craft-fonts has a face
|
||||
//! for it. Today that means Adobe-Japan1.
|
||||
//! 5. The ordering names a script we have **no** licensed face for (GB1, CNS1, Korea1). There is
|
||||
//! no honest substitute, so the chain reports none: the caller draws nothing and can say why.
|
||||
//! 6. Otherwise, the nearest of the standard 14 by `/FontDescriptor /Flags` — serif, fixed pitch,
|
||||
//! bold and italic. This step always succeeds, so a simple font is never left without a face.

//! The generated standard-14 tables: the fourteen base font names and their per-code advance

|

//!
|
||||
//! This file is the closed-list item in AGENTS.md 1.1 and carries a SHA-256 in `ATTRIBUTION.toml`,
|
||||
//! so `cargo xtask assets` fails until a change to it is re-attested. It is kept separate from the
|
||||
//! code that reads it for exactly that reason: if ordinary edits churned the hash, re-attesting
|
||||
//! would become reflexive and the check would stop meaning anything.
|
||||
//!
|
||||
//! Widths are in thousandths of an em, indexed by character code in each face's own encoding --
|
||||
//! WinAnsi for the twelve text faces, and their built-in encodings for Symbol and ZapfDingbats.
|
||||
//! A zero means the encoding leaves that code undefined. Verified against the published
|
||||
//! specification by the tests in `std14.rs`, which type the expected values in by hand.
