Explanation
The description covers the required sections in substance. It explains what changes and why (a redacted or sanitized copy gets a fresh /ID pair, with the design rationale tied to ISO 32000-2 section 14.4). It lists the affected public API (Document::require_full_save_with_new_id, Document::new_id_required, SaveOptions::id_entropy) and the crates touched. The verification section gives concrete commands and results on Windows, plus dependent-crate runs and a note on what was not run. The template's checklist items are addressed: fmt, clippy, tests, xtask checks, never-crash, provenance, and a note that Security and Parity do not apply. The 'Anything a reviewer should look at first' section lists specific judgement calls, including the hash choice, the performance measurement, the decision to keep remove_hidden unchanged, the encrypted-file ID handling, and WebAssembly entropy limits. Two gaps remain. The description does not say whether the 'Docs updated' item was done, although the README change in the summary suggests it was. The 'Tests' note says each new test was seen failing before the fix, which is good, but the description also says the redact test was seen failing with a specific assertion. The description does not mention the later remove_hidden follow-up in the body, although the review-status block and the objectives cover it. The description also contains a stale statement that remove_hidden is deliberately unchanged, which conflicts with the objectives and the raw summary, which say remove_hidden now requests a new identifier. That contradiction is material to a reviewer, because it changes what the PR does.
Resolution
Resolve the contradiction about remove_hidden. The body says remove_hidden deliberately keeps the identifier. The review follow-up and the raw summary say remove_hidden now requests a new identifier. Update the 'What this changes' section, the 'Anything a reviewer should look at first' section, and the 'Deliberately not changed' paragraph so they match the final behaviour. State which behaviour is intended. Also state the scope of the optimizer's discard option, because the description says that option would change output if remove_hidden changed. Confirm whether the docs template item is complete. The README change in the summary covers write_full documentation, so mark it accurately. Update the verification section to cover the final head: the description reports results for 6fb6b7c and a rebased head, but the review follow-up reports validation on 934dceb. Add the regression tests the follow-up cites, such as a_remove_hidden_copy_gets_a_new_identifier and separate_fresh_processes_get_different_identifiers, to the Tests section. Address the failing hosted CI job 'gate / gate (ubuntu-24.04)', or explain why it is not related to this change.

Use browser-session entropy for default WebAssembly identifiers.
A fresh WebAssembly instance resets COUNTER to zero, and WebAssembly uses fixed RandomState keys. When the same document produces the same written bytes, the default path can therefore produce the same /ID across browser sessions. Supply fresh browser entropy when id_entropy is None, while retaining id_entropy for deterministic tests.

Reviewed b99e617cc99ce9995945d6d3110c00591850a69b, including all eight changed files, the full/incremental writer and encryption context, redaction/sanitize callers, regression tests and prior review.
I independently confirmed that the existing WebAssembly entropy issue remains: id_salt at crates/cos/src/writer.rs:653–660 uses only RandomState and a process-local counter when id_entropy is absent. The engine’s save paths still leave that option absent. This does not supply fresh host entropy on wasm32-unknown-unknown; fresh equivalent instances following the same allocation/call sequence can reproduce the same salt and identifier for identical output. Please wire browser-provided entropy into this default path and cover separate fresh instances, while preserving explicit deterministic entropy for tests. I am referencing the existing thread instead of duplicating an inline finding.
Validation also remains blocked: CI failed the Windows panel_snapshots::every_panel_matches_its_snapshot test (search-panel mismatch), while Linux and wasm checks passed. The other reported platform workflows and SonarCloud passed. I have not established that the Windows failure is caused by this diff. GitHub currently reports the branch non-mergeable.
This was connector-based static review, not an executed Rust/browser test run; local validation in the PR is author-reported.

Both open items are addressed on the pushed head. The wasm entropy gap: with no explicit id_entropy the default salt now takes fresh bytes from the browser (crypto.getRandomValues through the crate's existing cfg-gated js_sys pattern, Math.random as a fallback), while explicit id_entropy stays deterministic for tests; fresh equivalent instances no longer share a salt. The integration gap: remove_hidden itself now requests the new identifier, so the optimizer's discard option and Edit > Remove Hidden produce a copy with a new /ID as well; sanitize keeps its request only for the NothingToApply branch. Regressions: a_remove_hidden_copy_gets_a_new_identifier (fails on the previous code) and separate_fresh_processes_get_different_identifiers (two fresh processes over one fixture get different identifiers). The branch is rebased on current main; the Windows panel-snapshot failure from the old head does not reproduce on the rebased branch. |

Re-reviewed 728594c.
The normal browser path now calls crypto.getRandomValues, addressing the original missing-host-entropy finding. The fallback still needs correction in browser_salt in crates/cos/src/writer.rs.
If the crypto property is absent/null, the function returns None before reaching Math.random. id_salt then uses the wasm RandomState/counter path that this change is meant to replace. Also, when getRandomValues is unavailable or throws, the fallback loop samples only four bytes: hashing those bytes into u64 does not increase their 32 bits of entropy, so identical rewrites can collide across fresh instances.
Please route unavailable/refused Web Crypto through a sufficiently sized fresh-entropy fallback, or return an explicit error rather than silently reverting to the deterministic path. Add browser-instance tests for the normal path and missing/refused API paths. The fresh-process native test explicitly does not exercise this wasm behavior.
Current hosted CI is green. This finding is from source and CI-log review; I did not run the app or local Rust tests.

The fallback chain in the browser salt is fixed in the pushed head: a missing or failing Web Crypto no longer returns early — it now falls through to the Math.random path, and that path mixes a full 16-byte salt from its draws through the same FNV folding instead of four bytes. The mixing step is factored out and unit-tested on the native target; the wasm-only control flow still cannot execute in this repository's checks (no browser harness), so that part is verified by the wasm32 compile gate and by construction, with the native fresh-process divergence test remaining the behavioural proxy. Explicit id_entropy stays fully deterministic. |

Working on the requested changes; an update will follow once it has been tested. |
A full save that the document asked for (Document::require_full_save_with_new_id) now writes a fresh /ID pair, so a redacted or sanitized copy does not claim to be the file it came from (ISO 32000-2 section 14.4). Ordinary saves are unchanged. An encrypted file keeps the first string of /ID, because the file key is derived from it, and gets a new second string. An encrypted file whose /ID is not a pair of strings is left as it was, as before. SaveOptions::id_entropy lets a caller or a test supply entropy; with it the new identifier depends only on that entropy and the written bytes. Without it the identifier mixes the standard library's random hash keys and a process-wide counter, the same facility the engine uses for new encryption keys. Checked: the new tests in crates/cos/tests/file_identifier.rs fail on the clean base (compile errors for the missing API), fail on assertions when only the API is in place, and fail again when each pinned line is reverted (the regeneration call, the first-string keep, the flag, the entropy input, and the ordinary-save guard). cargo test -p pdfcraft-cos passes, and clippy with warnings denied is clean. A probe that wrote 16 ordinary full and incremental saves gave byte-identical files with and without this change.
Applying redactions, sanitizing and removing hidden information now ask the cos layer for a new file identifier (Document::require_full_save_with_new_id), so the saved copy no longer carries the /ID of its source. Before this change the previous revision was dropped but the identifier still linked the copy to the original. The request sits in remove_hidden itself, because its per-category callers (the remove-hidden edit and the optimizer's discard option) call it directly, not through sanitize(). sanitize() asks only on its nothing-hidden path, where remove_hidden returned before asking: the rewrite is a new file either way. Checked: the new tests a_redacted_or_sanitized_copy_gets_a_new_identifier and a_remove_hidden_copy_gets_a_new_identifier fail before this change (the request is missing after apply, and after remove_hidden) and fail again when the apply call, the nothing-hidden branch or the remove_hidden request is reverted. cargo test -p pdfcraft-redact passes with the tests included (152 passed, 1 ignored); cargo clippy with warnings denied and cargo fmt --check are clean.
The writing section of the crate README described full saves without saying what happens to /ID. It now says that an ordinary save keeps the identifier, that a document which asks for a new one (redaction and sanitizing) gets both strings regenerated, that SaveOptions::id_entropy supplies entropy for reproducible output, and that an encrypted file keeps its first string because the key depends on it. Checked: the text matches the code added in e1f761cc (regenerate_id, new_id_bytes, require_full_save_with_new_id) and the tests in crates/cos/tests/file_identifier.rs. No code changed in this commit.
The identifier of a requested rewrite hashed only the first 64 KiB of the written file.
With caller-supplied id_entropy the identifier is deterministic, so two rewrites of
documents with the same length that differ only after byte 65,536 received the same
/ID, and a later edit of a large document could keep its previous /ID.
Every written byte is now hashed. The output is read once: one loop over 4 KiB chunks
feeds both halves of the 16-byte identifier, so the extra cost is one linear pass over
the output. Measured with a probe in the workspace dev profile (opt-level 1): hashing
64 MiB took 0.024 s, about 24 ms per 64 MiB of output. A release build was not measured.
Ordinary saves never reach this code, and their output is unchanged.
Checked: crates/cos/tests/file_identifier.rs gains
the_identifier_depends_on_the_whole_rewritten_file. It fails on the branch head before
this change ("content past 64 KiB must change the identifier", both identifiers equal)
and passes after it; reverting only the chunk loop to the 64 KiB prefix makes it fail
again. The six existing tests in that file pass, and so do the full cos and redact test
suites.
A requested rewrite of an encrypted file whose /ID was absent, had one entry, or had a first entry that is not a string wrote no identifier at all, although the document had asked for a new one. The reader takes the empty string as the key input for these shapes (Document::first_id), so the rewrite now writes the empty string (<>) as the first entry and a new second entry. The key stays valid. A file whose first entry is a string keeps that string, as before. Ordinary saves and unencrypted rewrites are unchanged. Checked: an_encrypted_rewrite_without_a_usable_identifier_still_gets_a_new_one in crates/cos/tests/file_identifier.rs covers the three shapes for RC4-128, AES-128 and AES-256. After the rewrite each file opens with its password, the first string is empty and the second is new. On the branch head the test fails with "the rewrite writes a pair" (left 0, right 2). Reverting only the guard to the head's early return makes it fail again. Isolated, the one-entry shape fails with left 1, right 2, and the non-string shape with left Some(0), right Some(16). The other seven tests in the file pass.
With SaveOptions::id_entropy the identifier was built with std's DefaultHasher, whose algorithm the standard library does not specify, and with write_usize (4 bytes on wasm32, 8 on 64-bit targets) and native-endian integers. The same entropy and the same file could therefore give different identifiers on different platforms or toolchains, although the documentation promised the bytes depend only on the entropy and the written file. The identifier is now FNV-1a (64 bit, the published constants) over fixed-width big-endian fields and the whole written file: the salt, the lane, id_seed and the length, then the bytes. With caller entropy the salt is the FNV-1a hash of that entropy. Without entropy it is still the standard library's random hash of a process counter, so only the salt differs between the two paths. Every written byte is hashed, in one pass that feeds both lanes. Cost: this pass is slower than the SipHash it replaces. A temporary probe in the workspace dev profile (opt-level 1) hashed 64 MiB through both lanes in 0.129 s (about 500 MiB/s), against 0.024 s before. A release build was not measured. The cost is paid once per requested rewrite; ordinary saves do not reach this code. Checked: the golden test fixed_entropy_rewrite in crates/cos/tests/file_identifier.rs pins the 16 bytes for a fixed entropy and the standard fixture. On the previous hash it fails (left [64, 145, ...], right [50, 125, ...]). An independent re-implementation of the same formula in Python, run over the bytes the writer hashed (everything before startxref), gives the same 16 bytes. The unit test fnv1a_is_the_published_64_bit_algorithm checks the constants against the published vectors. FNV is not collision-resistant against chosen content; that matters only if someone could choose a file's identifier, and the identifier only has to be unique.
Without SaveOptions::id_entropy the salt of a rewritten file's identifier was RandomState and a process-wide counter. On wasm32-unknown-unknown those hash keys are fixed at compile time, so two fresh web apps that followed the same allocation and call sequence reproduced the same salt and the same identifier for identical output, and a redacted copy stayed linkable to its source. The default salt now comes from the browser first: crypto.getRandomValues (Web Crypto, through js_sys, sixteen bytes folded with the same FNV-1a the identifier uses), or Math.random where that API is missing, and only when neither is reachable the previous RandomState salt. js-sys and wasm-bindgen join pdfcraft-cos as wasm32-only dependencies; both are already in the dependency tree of the web shell, and native builds compile neither. Caller entropy is untouched: with id_entropy the identifier is still a pure function of that entropy, the seed and the written bytes. Checked: separate_fresh_processes_get_different_identifiers re-runs this test binary as two fresh child processes over the same fixture and fails when the default salt is made constant (so does the in-process divergence test); stand_in_for_a_fresh_process is its no-op child half. Both pass with the real salt. On WebAssembly no browser test harness exists, so the browser path is covered by the wasm32 cargo check and by construction, not by a test. cargo check --target wasm32-unknown-unknown -p pdfcraft-cos passes, cargo test -p pdfcraft-cos and -p pdfcraft-redact pass, and clippy with warnings denied is clean on both.

What this changes
A redacted or sanitized copy no longer keeps the
/IDof the file it came from. Applying redactions and running Sanitize now make the saved copy write a fresh trailer/IDpair. Before, the previous revision was dropped, but the identifier still linked the copy to its original.This is a design choice, not something the specification requires: ISO 32000-2 (section 14.4) defines
/ID[0]as a permanent identifier that survives incremental updates of the same document. A redacted or sanitized copy is a new document derived from the original, so this PR gives it new strings in both positions. If you would rather keep/ID[0]and change only/ID[1], that is a one-line change; tell me which you prefer.pdfcraft-cos:Document::require_full_save_with_new_id()andDocument::new_id_required(). A flagged full save regenerates both/IDstrings. An encrypted file keeps/ID[0], which its file key is derived from (the empty string when the file had no usable first entry), and gets a new/ID[1].SaveOptionsgainsid_entropy: Option<[u8; 16]>: when it is given, the new identifier depends only on that entropy and the written bytes, so tests can pin output.pdfcraft-redact:applyandsanitize()request the new identifier.sanitize()does so whether or not it removed anything.Ordinary saves are unchanged. They write the same bytes as before (checked below).
Deliberately not changed:

crates/cos/tests/file_identifier.rs(9 tests) andcrates/redact/src/tests.rs::a_redacted_or_sanitized_copy_gets_a_new_identifier. Seen failing before the change: on the base the cos test file does not compile (the new methods and theid_entropyfield are missing); with only that API in place, three rewrite tests fail on their assertions; the redact test fails withassertion failed: doc.new_id_required(). Each production line the tests pin was then reverted in turn, and the test that pins it failed: in cos, the regeneration call, the encrypted first-string keep, the flag, the entropy input and the ordinary-save guard; in redact, theapplycall, the nothing-hidden branch and the hidden-information branch ofsanitize(). Each revert was restored and checked byte for byte.Two more tests came from the pre-review on the fork.

Anything a reviewer should look at first
The identifier is now a FNV-1a hash (the same family
ensure_idalready uses) over the whole written file, so it is stable across platforms and toolchains whenid_entropyis given. It is one linear pass over the output; in a debug build it measured about 0.13 s per 64 MiB, roughly five times the previous hash. A release build was not measured.The new identifier is random unless
id_entropyis given, so a redacted or sanitized copy is no longer byte-identical between two runs over the same input. No test in the suites run here depends on that.remove_hiddenkeeps the identifier on purpose. Applying the same rule there would also change the optimizer's output whenever it discards metadata, so that is a separate decision.An encrypted file whose
/IDis missing, has one entry or has a first entry that is not a string gets the empty string as its first entry, which is the string its key is derived from, and a new second entry. The file still opens with its password.On WebAssembly the standard library's hash keys are fixed, so there the identifier varies only with a process counter and the written bytes. Not tested in a browser.
The tests above were run on 6fb6b7c, then the branch was rebased onto 22bedbf (three commits: a version bump, README badges and a CodeRabbit config; none touches these crates) and the cos and redact tests were re-run on that head and on the later commits: cos 105 passed, redact 81 passed. The engine, automation and ui-egui suites were run on 6fb6b7c only.
Summary by CodeRabbit
New Features
Redacted or sanitized documents receive new file identifiers on their next full save, even when sanitization removes no content.
Full saves can generate reproducible identifiers when caller-provided entropy is provided.
Encrypted files preserve the identifier used for key derivation while updating the companion identifier.
Full saves preserve existing identifiers unless a new identifier is requested, and generate identifiers when none are present.
