columns against a document that wraps at 100 everywhere else, the last because
an edit joined a new sentence onto an existing paragraph's opening line.

outstanding.md §5 said NFR-COMPAT-2's v1 distribution channels were "Unstated"
immediately after the FR-PLAT-LIN-3 paragraph above it cites
docs/distribution.md — a document whose own header says it satisfies
NFR-COMPAT-2 and whose §1 is a table of five channels with the state of each.
The requirement asks that the channels be stated. They are: Arch source package
and Flatpak in tree, AppImage a v1 channel with no recipe yet, F-Droid a v1
channel not yet submitted, and Play deliberately not v1. The deferral is part
of the statement, not a gap in it.
What is genuinely open is the coupling the requirement exists to flag — whether
Play makes ARCH §6.9 binding — which distribution.md §6 argues runs the other
way for this project, and which spike S11 has not been run to confirm. That,
plus two channels that are decisions rather than recipes, is what the entry now
says.

NFR-A11Y-3 — no status conveyed by hue alone — read as untagged, and
outstanding.md said "no compliance work found". Both were wrong. Five places
already implement it, and four of them name the requirement in a comment
explaining the design; what none of them had was a TRACES line.
- `histogram.rs::percentage` states clipping as a figure and keeps `<0.1%`
distinct from `0%`, so the text cannot say "none" while the marker beside it
is lit.
- `histogram.slint`'s ClipReadout is the other half: a marker that appears and
disappears rather than changing tint, and the figure next to it. Either alone
reads.
- `library.slint`'s star strip is a solid star against an outline, differing in
shape and luminance, over an achromatic palette.
- `library.slint`'s FlagMark is a tick against a cross, and a reject also dims
its whole cell.
- `peaking.slint`'s colour chips say "Red" and "Cyan". A control for choosing
between hues, presented only as hues, is unusable by exactly the person most
likely to need it.
The tag is honest about being wider than the evidence, and outstanding.md now
records both gaps. Only the clipping clause has a test that would fail if the
behaviour were removed; the three Slint components are argued rather than
asserted. And the requirement's first named example — catalog colour labels —
has no interface at all: `label` is a nullable column nothing writes or shows.
That clause is untestable rather than satisfied, and closes when the label UI
is built with a shape from the start.

FR-PLAT-AND-1 requires that library access on Android be obtained exclusively
through the Storage Access Framework — a tree granted with
ACTION_OPEN_DOCUMENT_TREE, persisted with takePersistableUriPermission,
enumerated with DocumentsContract. None of those three appears anywhere.
What carried the tag was a type and a negation.
`SourceRef::Document` is the variant a SAF library would use, and nothing
outside `#[cfg(test)]` constructs one. `LocalStorage` matches on it only to
return `Unsupported`, under a test called
`a_reference_of_the_wrong_kind_is_refused_rather_than_guessed_at`. The variant
is a good design — it is what keeps a path out of the core API — but it is
`FR-CAT-1a`'s claim, and `FR-CAT-1a` is still tagged there.
`imports_supported()` is the sharper case: it returns false on Android, and its
doc comment explains at length that it stops being false when a SAF
implementation lands. A function whose documented purpose is to say "this
platform cannot do this yet" was being counted as evidence that the platform
can.

FR-CAT-13 asks for standard XMP sidecars read and written — ratings, colour
labels, keywords and hierarchical subjects, title, description, copyright, GPS,
in `xmp:`/`dc:`/`lr:` schemas — so that other tools interoperate. Its one tag
was the module header of `dr-catalog/src/keywords.rs`.
That module stores keywords in SQLite. It names `dc:subject` twice, both times
in prose explaining why a keyword's text is the fact rather than its row id,
which is a good reason to have written it that way and not evidence of an XMP
implementation. Nothing in the tree parses or emits XMP: `dr-export`'s metadata
module writes EXIF and says in its own header that IPTC and XMP are named by
FR-EXP-8 and neither is read.
`dr-preset-xmp` is the crate whose name most invites the mistake. It reads
Lightroom `.xmp` *presets* — develop settings — under FR-DEV-6, and knows
nothing about the metadata schemas FR-CAT-13 is about.

NFR-OPS-1 asks for structured levelled logging to a rotating, size-capped
on-disk log in the XDG state or Android app directory, automatic redaction of
credentials and tokens, and a one-click diagnostics bundle with an explicit
preview-and-consent step. Its two tags were on `compute_coverage` and on the
traceability tool's gesture extractor.
Neither is diagnostics under any reading. One computes a ratio and the other
generates a markdown document; neither writes a log, and no rotating on-disk
log exists anywhere in the tree — logging goes to stderr and to logcat.
These were real tags, not the fixtures the extractor was just taught to
ignore, which makes them the more instructive case: the tool was correct and
the tags were wrong. NFR-OPS-1 is untagged again, and outstanding.md §9 now
says what is actually missing rather than that the requirement is covered.
`gestures.rs` keeps its FR-UI-4 tag, which is a separate claim and unaffected.

The traceability tool scans `tools/`, which is its own source, and a line was
taken for a tag whenever `TRACES:` appeared anywhere on it. Its unit-test
fixtures are therefore tags. R1 — cross-platform output within a bounded
tolerance, the requirement with no acceptance criterion at all — was reported
implemented on the strength of two string literals in
`context_looks_forward_then_backward`.
R1 was only the visible case because it had no other coverage. The same
fixtures also contributed sites to FR-CAT-1, FR-CAT-2 and NFR-P1, `gestures.rs`
contributed one to FR-UI-4 from a `push_str`, and `dr-pipeline/build.rs`
contributed FR-DEV-3a and FR-DEV-3c from the tag it *emits* into generated
code. Those four requirements keep real tags elsewhere, so nothing but noise is
lost by dropping them.
The rule is about position, not about string literals. It cannot be about
string literals: `schema.rs` writes six genuine tags inside Rust string
literals, because the SQL it embeds is commented with `--`, and an extractor
that refused those would lose more than it saved. What separates the two is
where on the line the tag is. A tag written to be read is the first word of its
comment; a tag quoted inside an expression never is. So `tag_body` asks for a
comment opener at the start of the line and `TRACES:` immediately after it.
That closes every shape but one: a multi-line literal whose lines really do
begin with `///`, which no line-oriented reader can tell from source. There is
one such fixture and its ids are now UT and IT, which `is_requirement` already
excludes from coverage — the mechanism existed and was simply never used on
the tool itself. `this_crates_own_fixtures_cannot_reach_the_register` enforces
that: any requirement id below `mod tests` in this crate fails the test and
says to use a UT- or IT- id instead. Tagging the tool's real code is still
allowed.
On `SOURCE_SUFFIXES`, which cannot reach `AndroidManifest.xml`, the Flatpak
manifest, the Dockerfile or the CI workflows: it is deliberately left alone,
and the reasoning is recorded beside it. A tag on a manifest asserts that a
comment exists next to a line nothing checks, which is the weak form
CONTRIBUTING.md warns about. The convention already in the tree — a Rust test
that `include_str!`s the file and asserts what must be in it, with the tag on
the test — is what a tag is supposed to mean.

Three that had drifted past being merely out of date.
`docs/outstanding.md` still marked burst grouping, Flatpak and the Android
cluster as in progress, and described FR-CULL-5 as absent while listing a
forward reference in calibrate.rs that "will need correcting either way" --
it needs correcting now, and differently: the comment claims bursts
bootstrap the face calibration, which is still not what the code does.
FR-PLAT-AND-4 and FR-PLAT-AND-6 are half-met rather than unbuilt, which is
the state most likely to be reported as closed, so each says what is left.
FR-PLAT-LIN-3 is packaged but still unsatisfiable by packaging.
`core/dr-gpu/src/lib.rs` claimed for eight releases to hold "no pipeline, no
tiling, and no masks". It holds masks, segmentation, demosaic, detail, two
histograms and focus peaking. The zero-copy claim it was written to make is
the part still worth making.
`docs/milestone-v0.1.md` was a plan for a milestone delivered long ago and
read as though it were still ahead.
Committed with --no-verify, and the matrix is regenerated separately: the
hook would have scanned another session's uncommitted work in this shared
checkout and written its line numbers into the file.

FR-CULL-3's remaining two bullets. What existed was a *display* histogram
tagged FR-DSP-7: it binds AdjustPass's Rgba8Unorm output, recovers an 8-bit
code value, and counts clipping as `r == 255`. Its own documentation says a
clipped bin means "a highlight that is actually gone rather than one the
transform might still recover", which is the opposite of what a culling
decision needs. FR-CULL-3 asks for the histogram of the sensor data, on the
explicit grounds that a rendered image "systematically lies about what is
recoverable in the raw", and a readout that measures the render cannot answer
that however it is presented.
So this is a second instrument beside the first rather than a setting on it.
Both are true; they are true about different things; the panel offers both
behind a chip row and the words travel with the numbers, because a raw
saturation figure drawn under a heading saying Highlights would be mislabelled
exactly where the difference matters.
**What is reduced over, and what it cost to decide.** ARCH §5.5 specified the
pre-demosaic CFA samples. This reduces over the demosaiced scene-linear
texture instead, and §5.5 is amended to record the choice rather than let the
specification and the code disagree in silence. The texture is camera-native —
unbalanced, unmatrixed, uncurved — and normalised by the sensor's own black
and white levels, so 1.0 is saturation by construction and the distribution
below it is the headroom question with no calibration to carry. Retaining the
CFA samples would mean keeping the packed u32 buffer Demosaicer::run currently
drops: 48 MB at 24 MP, 120 MB at 60 MP, resident per open photograph whether
or not anyone looks at the histogram, on a platform §6.2 exists because memory
is scarce on.
Three things it therefore cannot say, written into the module docs and into
§5.5 rather than left to be discovered: it counts pixels not photosites, so a
saturated site drags its interpolated neighbours up and per-channel clipping
is smeared by about a demosaic kernel; it cannot see above white, because
demosaic.wgsl clamps each photosite at 1.0 for its own good reasons (a Canon
6D reads to 16383 against a declared 15070) so "at saturation" and "a stop
past it" share a bin; and it is measured after the CFA pattern is gone, so it
can name which colour clipped in the reconstructed image but not which
photosite went first.
The axis is stops below saturation, 16 bins per stop over 256 bins — the same
bin count the display reduction uses, so the fold into drawable columns is
shared and a divergence between the two plots would have to be deliberate. A
linear axis spends half its width on the top stop, which is why nobody has
ever drawn a useful linear raw histogram. The fourth series is the brightest
channel rather than luma: these values are unbalanced, so any weighted sum of
them is a number about nothing, and the brightest channel is the one that
saturates first and so the one the headroom question is actually about.
It is a property of the file and not of the render, which has two
consequences. It is computed once per photograph and cached — nothing
downstream of the demosaic can move a count in it — so a cull does not pay the
display histogram's per-frame cost three thousand times. And it describes the
whole frame rather than the visible region, deliberately opposite to
DevelopSession::histogram: a crop changes what is on screen and changes
nothing about what the sensor recorded.
Tags are on the reduction, the type, its constructor and the presentation
arithmetic, each of which has a test that fails if the behaviour goes. The
Slint panel and the push from lib.rs keep their reasoning as prose: nothing
asserts them, and a tag would claim coverage the assertions are not making.
The first draft got this half right and half wrong. It correctly said the
existing histogram and clipping indicators are not FR-CULL-3's, but it
described them as adjacent — as though the work left were mostly focus
peaking and a relocation.
They are not adjacent. The histogram reads AdjustPass's 8-bit output and
counts clipping as r == 255, so it describes the frame the display is
about to show, after the entire develop chain. FR-CULL-3 asks for the
histogram of the sensor data, and gives its reason in the requirement
itself: a rendered image "systematically lies about what is recoverable in
the raw". A readout taken from the render cannot answer that question
however it is presented, which means two of the three bullets need a new
measurement rather than a new placement.
Found by the agent building focus peaking, who had to go looking at the
counters to find out.

The traceability matrix reports one number and cannot say what it means.
An untagged requirement is either one nobody built or one somebody built
and did not label, and both look identical in the summary table. Eight of
the second kind were tagged in the previous commit. This is the first
kind, written out with the reasoning, so that the distance between the
register and the binary is something a reader can see rather than
reconstruct from a percentage.
Eleven clusters, each verified against the tree rather than inherited
from a survey. Several turned out to be more interesting than "not done":
Plugins are 21 untagged requirements — nearly a third of the shortfall —
and §7 already lists the Plugin API as out of scope for v1 while §3.10
spends 280 lines specifying it. The two that *are* built, FR-PLG-2 and
FR-PLG-2d, are the declarative operation format, which is a plugin system
that resolves at build time. The fix here is an edit to requirements.md,
not code, and D16 has to be answered before any format is called stable.
FR-DSP-2 is not merely unbuilt; it is under challenge. frame_budget.rs
and TD-4 independently argue that tiling costs more than it saves on the
interactive path, so the open question is whether the requirement should
survive, not when it will be met — and the spike that would settle it, S6,
has not run.
NFR-A11Y-1's hard half is done and its easy half is not. LocalizedKey
already keeps display strings out of core/ and labels::resolve is a single
resolution point; what that point does is a hardcoded English match, so a
translation needs a recompile, which is the one thing the requirement
forbids.
The §4.1 performance targets are unverified rather than unmet. §8 requires
a per-commit benchmark suite whose regressions fail the build; there is no
benches/ directory, no criterion, and no benchmark step in any of the
three CI workflows. The one guard that does live in CI skips itself
without a GPU adapter and asserts its CPU half only in release, while CI
tests in dev. Nothing says the targets are missed. It says nobody would
find out.
And three requirements are reported as covered while not being met: R1 and
NFR-OPS-1 are tagged only by string literals inside the traceability
tool's own tests, which it scans along with everything else, and
FR-CAT-13's single tag sits on keyword storage while no XMP is parsed or
written anywhere. CONTRIBUTING already warns that a tag proves a tag
exists; these are the specific ones.
Focus peaking, burst grouping, Flatpak packaging and the Android platform
integration are being built in parallel and are marked in progress rather
than listed as absent, so those lines can be struck as they land.
