User description

A repo-wide pass for over-engineering: what the standard library already
ships, what one dependency was doing for one function, and what nothing
reaches at all. No behaviour changes except where noted below.

What went

48 map-key-collect-and-sort loops slices.Sorted(maps.Keys(m)), or slices.Collect where the original did not sort
22 linear searches returning a bool slices.Contains / slices.ContainsFunc
10 functions deadcode -test ./... cannot reach deleted
logging.Clock, realClock, SystemClock deleted — a clock seam with no injection point
two scheme registries written out in full one generic internal/adapters/scheme
glamour nothing — notes print as the vendor wrote them
minisign.reverse, ui.atoiSafe slices.Reverse+Clone, strconv.Atoi
imagepack.Source oras.ReadOnlyTarget, which is all it ever was
68 files changed, 482 insertions(+), 773 deletions(-)
go.mod:  -1 direct dependency, -9 indirect
binary:  36.96 MB -> 30.23 MB (-18%)

slices and maps appeared 9 times across internal/ before this, on a
module that requires Go 1.25. Two of the hand-rolled versions had grown
their own insertion sort rather than import one; exec.sortedKeys carried
a comment explaining that it "keeps the package free of a sort import for
one call".

The two that are more than mechanical

internal/adapters/scheme. The target registry's package comment
already said it: "deliberately the same shape as the release-source
registry [...] a second registry shape for the same problem would be a
second thing to keep honest." The copies had drifted where it matters.
target.Registry.Close walks the argument list, with a comment explaining
that deduplicating through a set keyed by the interface value panics for an
adapter whose dynamic type is not comparable. source.Registry.Close still
built exactly that set — latent, since no shipped source is a value type,
but one adapter away, at shutdown. The source registry also skipped a nil
silently, leaving a build missing a transport that failed at fetch time as
though it had never been compiled in; it is refused at startup now, like a
nil target always was.

Line count there is a wash: -156 across the two files, +125 in the package
they share. The point is one copy of the invariants. It carries its own
tests, and both fail against the shape they replace — the typed-nil case
against a plain == nil check, and the close walk against the set-keyed
dedup, which panics.

Release notes. RenderNotes was glamour's only caller anywhere, and
glamour was the only reason ten modules were in the build: goldmark, an
emoji extension, chroma, regexp2, bluemonday, douceur, gorilla/css, reflow
and x/exp/slice. What all of it bought was colour on a release note, in a
tool whose reason for existing is deploying to a machine that cannot reach
a registry. The function's own documentation already said the alternative
is fine — plain mode "gets the source text, which is what a vendor wrote
and is readable on its own".

Nothing renders or reflows them now. An intermediate commit wrapped to the
same 80 columns glamour was asked for; CodeRabbit caught that wrapping
Markdown corrupts it, and the reproduction is a fenced block split across
--wait-for- and health — a command an operator copies. Deciding which
lines may be reflowed means parsing Markdown, which is a renderer, which is
what came out. So RenderNotes is deleted rather than repaired: without the
wrapping it was strings.TrimSpace with an unused mode parameter.

test/suite/channel_test.go pins that the notes survive the fetch whole,
since the property is now the absence of a transformation and nothing else
was watching it.

The user-visible changes, all in release notes: they are no longer
styled, they are not reflowed, and terminal control sequences are stripped
in every mode (below).

Vendor notes no longer reach the terminal unfiltered. release.Notes
returned the bundle's bytes untouched, so a RELEASE.md carrying
\x1b]52;c;… wrote the operator's clipboard the moment they ran update --check, and NotesSummary put the same bytes into a notification body
that leaves the machine — past this project's own rule that raw
vendor-controlled output is withheld from notifiers
(ops.forwardedKinds refuses KindStepOutput).

Filtered at the reader, so the webhook is covered by the same guard as the
terminal: ansi.Strip for whole sequences, then a rune pass for the bare
C0/C1 controls it leaves — \r and \b are not escape sequences and
either lets a vendor overwrite a line the operator has already read.

This one is pre-existing, not introduced here: reproduced identically on
main, where plain and JSON already returned raw bytes. It surfaces in this
PR only because rich mode used to be sanitised as a side effect of glamour.

Two findings from the audit that are not here

renameio, flagged as one dependency for one call site. Written out, the
replacement is 21 lines against 15 — os.CreateTemp, Chmod, Write,
Sync, Close, Rename, each with its own error branch and a cleanup
defer that has to survive the successful rename. Hand-rolling an atomic
replace in the path that writes secret state, to drop one module, is the
trade going the wrong way.

ports.Signer, ports.SignatureChecker and ports.HookRunner, flagged as
interfaces with one implementation and no test double. They are the
layering boundary, and .golangci.yml enforces it: depguard denies
internal/lifecycle importing internal/adapters. Their job is the
dependency arrow, not a second implementation.

Not converted

The two loops in Status.Healthy look for the absence of a failure.
!slices.ContainsFunc(s.Health, func(h) bool { return !h.OK }) is a double
negative that reads worse than the loop.

Verification

lint (0 issues), fmt-check, tidy, runtime-check, docs-check,
log-check, test-race, and go vet under docker, race,
docker,race and GOOS=darwin. Container lane: ./internal/... 39
packages ok, ./test/suite/ ok. Acceptance lane passed.

deadcode -test ./... reports nothing.

One thing the container lane found, and one it did not

Deleting imagepack.Source passed go build ./..., go vet ./..., go test ./..., lint, test-race and docs-check while the tree was
already broken: the remaining caller is behind //go:build docker, which
none of those compile. Fixed in 7d79e0e; every tag combination is vetted
now.

Five tests in test/suite/signing_docker_test.go and
attest_docker_test.go fail on this machine because alpine:3.20 no
longer carries minisign. All five fail identically on main — not
introduced here, and not fixed here. Worth its own issue, because the
interesting half is that TestAnEditedAttestationFailsVerification asserts
require.Error and therefore goes green for the same missing tool that
turns its five siblings red. The fixture also discards apk's stderr, so a
missing package reads as a bare exit status 1 after a 120-second wait.

Summary by cubic

A repo-wide pass for over-engineering: code the standard library already provides, a dependency that existed for one function, and functions nothing reaches. The only user-visible changes are in release notes: they are no longer styled or reflowed, and terminal control sequences are now stripped in every mode.

Release notes

  • RenderNotes is deleted; notes print un-wrapped in every mode, since wrapping vendors' Markdown breaks fenced command blocks.
  • glamour is dropped, the only dependency that supported the old rendering, and the binary drops from 36.96 MB to 30.23 MB.
  • release.Notes strips OSC/CSI/SGR/DCS sequences and bare controls like CR and backspace, which could otherwise let a vendor retitle the window, write the clipboard, or overwrite a line the operator already read; newline and tab survive.
  • A channel test pins that staged notes arrive whole, asserting a fenced command survives the fetch unbroken.

Refactors

  • 48 map-key-collect-and-sort loops become slices.Sorted(maps.Keys(m)), and 22 linear bool searches become slices.Contains/ContainsFunc.
  • Ten unreachable functions are deleted, including the logging.Clock seam.
  • imagepack.Source is gone; callers name oras.ReadOnlyTarget directly.
  • The two scheme registries now share internal/adapters/scheme, and the source registry refuses a nil adapter at startup instead of skipping it.
  • ui.atoiSafe now parses with strconv.Atoi but still refuses a signed COLUMNS, so +80 falls back to the assumed width.
  • Status.Healthy keeps its loops; renameio and the port interfaces stay.

Written for commit bc3ff9e. Summary will update on new commits.

CodeAnt-AI Description

Centralize adapter validation and simplify release-note output

What Changed

  • Release sources and backup targets now reject missing adapters, empty registrations, and duplicate scheme claims during startup instead of failing later.
  • Adapter shutdown closes each registered adapter once, continues after individual close failures, and supports non-comparable adapter values without panicking.
  • Rich release notes are wrapped to 80 columns without adding styling or requiring the removed Markdown-rendering dependency; plain and JSON output remain unchanged.
  • Replaced repeated collection and search logic with standard library helpers while preserving stable ordering and existing command results.
  • Removed unreachable options, APIs, and error paths that were not used by production or tests.

Impact

✅ Earlier configuration errors for unsupported or duplicate transports
✅ Safer adapter shutdown without skipped cleanup or panics
✅ Smaller dependency footprint and simpler release-note output

`deadcode -test ./...` reports ten unreachable functions: symbols that no
production path and no test calls. Each was reachable once or was written
against a caller that never arrived, and every one of them is a thing a
reader has to rule out before trusting the code around it.

Deleted, with what made each dead:

  - `https.WithAttempts`, `https.WithLimits`, `oci.WithLimits`,
    `oci.WithMaxBlobSize` — functional options nobody passes. Their fields
    keep their defaults, which is what every caller already relied on.
    `local.Source.WithLimits` goes with them: the two `WithLimits` options
    were its only callers.

  - `domain.SigningKeyMismatch` and `ErrSigningKeyMismatch` — the refusal
    RFC 0028 §5.4 describes was never wired to a producer, so no error in
    the system carries the sentinel and `ExitCode` never sees it. The
    behaviour it describes is unimplemented either way; a constructor that
    only documents an intention reads as though it were enforced.

  - `exec.Redact` — its own doc says "exported for the logging handler",
    and the logging handler does not call it. `logging` has its own
    redactor.

  - `engine.Engine.Bus` — presenters subscribe through the bus the CLI
    already holds and passes to `engine.New`.

  - `engine.FailurePolicy.String` — nothing formats a policy.

  - `engine.State.Output` — subprocess output reaches the live view
    through the exec output sink wired in `cli.wireAt`, which publishes
    `KindStepOutput` directly. This was a second route to the same event
    that no step ever took.

  - `ops.DescribeSettings` — `views.settingsDoc` renders `SettingsReport`
    for both rich and plain modes.

  - `logging.Clock`, `realClock`, `SystemClock` — a clock seam with no
    injection point. Zero references outside their own declaration.

`deadcode -test ./...` now reports nothing.
Forty-eight places built the same slice by hand: allocate with the map's
length, range it, append each key, sort. `slices.Sorted(maps.Keys(m))` is
that, and it has been in the standard library since Go 1.23 -- this module
requires 1.25.

Where the hand-rolled version did not sort, `slices.Collect(maps.Keys(m))`
replaces it, so the iteration order stays exactly as nondeterministic as it
was and no caller silently acquires an ordering guarantee it did not have.

Two of them had grown their own sort rather than import one:

  - `exec.sortedKeys` carried an insertion sort with a comment explaining
    that it "keeps the package free of a sort import for one call". The
    package now imports `slices` instead, and the sort is gone.

  - `compose.Services` had the same insertion sort inline.

Four single-caller `sortedKeys` helpers -- in `views`, `compose`, `exec`
and `cli` -- were four spellings of the same idiom; each is now one call at
the site that wanted it.

No behaviour changes. `go test ./...` passes.
Twenty-two places walked a slice looking for one element and returned a
bool. `slices.Contains` and `slices.ContainsFunc` are that, and the module
already requires the Go version that ships them.

Four were helpers whose whole body was the loop -- `containsComponent`,
`domain.containsString`, `logging.contains`, `runtimecheck.containsFinding`
-- and the two or three call sites each had are now the call itself.

The rest keep their names, because the name is what the caller reads:
`Mode.Valid`, `isSupportedAPIVersion`, `isParameterType`, `allTrue`,
`componentSelected`, `hasCold`, `IsTarZst`, `hasRecoveryRecipient`,
`anyRunning`, `anyOccupies`, `mentioned`, `Unreachable`, `Scripted.Ran`.
Their bodies are one call now.

`apply.anyRunning`'s loop was a second copy of `status.anyRunning` over the
same type; it calls it.

Not converted: the two loops in `Status.Healthy`, which look for the
*absence* of a failure. `!slices.ContainsFunc(s.Health, func(h) bool {
return !h.OK })` is a double negative that reads worse than the loop, and
the point of this sweep is the reader, not the line count.

Two more hand-rolled standard library functions go with them:

  - `minisign.reverse` is `slices.Clone` plus `slices.Reverse`. It keeps
    copying rather than reversing in place: both callers pass a slice of a
    key id array the caller still holds.

  - `ui.atoiSafe` parsed decimal digits by hand to reject anything that is
    not a plain bounded number. `strconv.Atoi` plus the same bounds check
    answers the same for every input the tests pin -- "", "0", "-1",
    "80x24", "abc", "10001", "999999999999" -- and now also reads "+80",
    which the hand-rolled loop refused for no reason anybody stated.
The target registry's own package comment said it: "deliberately the same
shape as the release-source registry [...] a second registry shape for the
same problem would be a second thing to keep honest." Two copies of one
shape is what that costs, and they had already drifted apart in the place
it matters most.

`target.Registry.Close` walks the argument list, with a comment explaining
that deduplicating through a set keyed by the interface value panics for an
adapter whose dynamic type is not comparable -- a target implemented on a
value with a slice field. `source.Registry.Close` still built exactly that
set. No shipped source is a value type, so the panic was latent rather than
live, but it was one adapter away, at shutdown, where the error has nowhere
to go.

`internal/adapters/scheme` now holds the shape once: indexing, the wiring
refusals (nil adapter, duplicate scheme, empty build) and the close walk,
over a type parameter constrained to `Schemes() []string`. Both registries
embed it and keep only what genuinely differs -- their port's methods, and
a refusal worded for the operator who typed a reference or a URL.

The nil check is now the reflect-based one on both sides. The source
registry used to skip a nil silently, which left a build missing a
transport that failed at fetch time as though it had never been compiled
in; it is refused at startup like a nil target always was.

Line count is close to a wash: -156 across the two registries, +125 in the
package they share. The point is the invariants, which now hold for both
because there is one copy of them rather than because both were remembered.

`internal/adapters/scheme` carries its own tests. Both fail against the
shape they replaced: the typed-nil case against a plain `== nil` check, and
the close walk against the set-keyed dedup, which panics.
`RenderNotes` was the only caller of glamour anywhere in this project, and
glamour was the only reason ten modules were in the build: a Markdown
parser (goldmark), an emoji extension, a syntax highlighter (chroma) with
its own regexp engine (regexp2), an HTML sanitiser (bluemonday) and the CSS
parser it needs (douceur, gorilla/css), plus reflow and x/exp/slice.

What all of that bought was colour on a release note. The function's own
documentation already said the alternative is fine -- plain mode "gets the
source text, which is what a vendor wrote and is readable on its own" --
and Markdown is a format whose entire premise is that the source reads as
prose.

Rich mode now wraps to the same 80 columns glamour was asked for, with
`ansi.Wordwrap` from `charmbracelet/x/ansi`, which this project already
depends on directly for measuring tables. Wrapping is the part that was
doing work: a vendor who writes a paragraph as one long line still gets it
broken to a readable measure. Plain and JSON modes are unchanged.

  go.mod:  -1 direct dependency, -9 indirect
  binary:  36.96 MB -> 30.23 MB (-18%)

The rich-mode test asserted content rather than escape codes, so it still
holds; it is renamed for what it now checks, and a second one pins the wrap
itself, since wrapping is the only thing rich mode still does.

A deployment tool that must run on a machine with no registry access was
linking an HTML sanitiser. It is not any more.
`imagepack.Source` was `interface { oras.ReadOnlyTarget }` and nothing
else: no method of its own, one embedded interface, and every value that
ever satisfied it was already an `oras.ReadOnlyTarget`. What it added was a
second name for the same contract, so a reader who found `OpenSource` had
to follow one more hop to learn that a source is what oras copies from.

`OpenSource` and `openRegistry` name `oras.ReadOnlyTarget` directly.
`imagepack.Source` is gone, and the one caller behind `//go:build docker`
did not rebuild with the rest -- `go build ./...` and `go test ./...` do not
compile a tagged file, so the deletion looked clean and was not.

It names `oras.ReadOnlyTarget`, like every other caller now does.

`go vet` under `docker`, `race`, `docker,race` and `GOOS=darwin` is clean.

📝 Walkthrough

Walkthrough

The change adds a shared generic adapter index, updates source and target registries, sanitizes release notes, changes note output and width parsing, removes obsolete APIs, and replaces manual collection and search logic with maps and slices helpers.

Changes

Adapter registration and API updates

Layer / File(s) Summary
Shared adapter scheme index
internal/adapters/scheme/*, internal/adapters/source/registry.go, internal/adapters/target/registry.go
Adds generic adapter validation, scheme lookup, sorted scheme reporting, and error-joining close behavior. Both registries embed the shared index.
Source and helper API cleanup
internal/adapters/imagepack/*, internal/adapters/source/*, internal/domain/errors.go, internal/infra/exec/redact.go, internal/infra/logging/logging.go, internal/lifecycle/ops/settings.go
Removes obsolete interfaces, options, sentinels, wrappers, and formatting helpers.

Release notes and UI behavior

Layer / File(s) Summary
Release note sanitization
internal/release/notes.go, internal/release/notes_test.go
Removes ANSI and other terminal control sequences while preserving visible text and Markdown constructs.
Note output and width parsing
internal/cli/commands.go, internal/ui/mode.go, internal/ui/measure.go, internal/ui/screen_test.go, internal/cli/groups_internal_test.go
Notes are printed after trimming without Markdown rendering. Width parsing rejects malformed, negative, oversized, and leading-plus values.

Mechanical standard-library rewrites

Layer / File(s) Summary
Collection and membership helpers
internal/adapters/**, internal/cli/*, internal/domain/*, internal/infra/*, internal/lifecycle/*, internal/ui/views/*, tools/*
Replaces manual loops, map-key collection, insertion sorting, and membership checks with maps.Keys, slices.Collect, slices.Sorted, slices.Contains, and slices.ContainsFunc. Existing ordering and matching behavior remains unchanged.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to bc3ff

This PR simplifies internal implementations, removes unused dependencies, and changes release notes to remain unstyled while stripping terminal controls. No actionable merge-blocking risk remains after normal checks and review.

Explanation

The description gives substantial, relevant detail about the changes and verification. However, it omits several template sections, including RFC, Type, Design, Lifecycle invariants, Compatibility, Secrets & safety, and Risk & rollback. It also contains contradictory generated text stating that rich notes are wrapped to 80 columns, while the change removes wrapping.

Resolution

Update the description to include and complete the repository template sections. State the RFC or why none is required, select the change type, document design and lifecycle impacts, confirm compatibility and safety requirements, record verification results, and describe operational risk and rollback. Remove or correct the stale CodeAnt-AI statement about wrapping rich release notes.

Wrapping vendor Markdown to a column corrupts it. A fenced block is the
clear case, and it is the one that costs an operator something:

    ```sh
    morzer apply --installation demo --profile production --release 1.4.0 --wait-for-
    health
    ```

That is the output of the previous commit, reproduced before this fix. A
table row past the measure splits the same way. Whether a line may be
reflowed is a question about Markdown structure, and answering it means
parsing Markdown -- which is a renderer, which is the dependency the
previous commit removed on the grounds that colour did not justify it.

So nothing reflows them. `RenderNotes` is gone rather than fixed: with the
wrapping removed it was `strings.TrimSpace` with an unused mode parameter,
and the two callers say that themselves now. Notes reach the operator as
the vendor wrote them, in every mode -- which is what plain mode already
did, and what the deleted function's own documentation gave as the reason
plain mode was fine.

Reported by CodeAnt on #72. The wrapping was not a requirement this project
had; it was introduced one commit ago to keep rich and plain distinguishable,
and that distinction is not worth a Markdown parser or a broken command line.

Two comments that claimed RenderNotes holds the 80-column line are corrected:
`ui.MaxContentWidth` and `TestHelpLinesFitEightyColumns`.
Replacing the hand-rolled digit loop with `strconv.Atoi` widened what
`atoiSafe` accepts: the loop rejected anything that was not an ASCII digit,
and `Atoi` reads a leading sign. `COLUMNS=+80` went from "fall back to the
assumed width" to "the terminal is 80 columns wide".

The commit that did it called the widening out and let it stand. That was
the wrong call for a refactor whose whole claim is that behaviour is
unchanged, and nobody asked for the wider input. Reproduced against the
previous commit -- `COLUMNS=+80` came back as a known 80-column screen --
and refused again here.

`-1` was already handled by the `n < 0` bound; only the plus needed saying.
`screen_test.go`'s malformed-value list carries `+80` now, so the parity is
pinned rather than restated in a comment.

Valid. Swapping the hand-rolled digit loop for strconv.Atoi widened what atoiSafe accepts: the loop rejected any byte that was not an ASCII digit, Atoi reads a leading sign, so COLUMNS=+80 went from falling back to the assumed width to reporting a known 80-column screen. Reproduced against the previous commit before changing it.

-1 was already covered by the n < 0 bound; only the plus needed saying. screen_test.go's malformed-value list carries +80 now, so the parity is pinned rather than asserted in a comment.

valid. swapping the hand-rolled digit loop for strconv.atoi widened what atoisafe accepts: the loop rejected any byte that was not an ascii digit, atoi reads a leading sign, so columns=+80 went from falling back to the assumed width to reporting a known 80-column screen. reproduced against the previous commit before changing it.

fixed in 13b5978.

Answer:
Resolved in 13b5978.

strconv.Atoi accepts a leading +, unlike the previous ASCII-digit-only parser. The added strings.HasPrefix(s, "+") check preserves the old behavior, so COLUMNS=+80 now falls back instead of producing a known 80-column screen. The malformed-value test also includes +80 to prevent regression.

📢 Thoughts on this report? Let us know!

Deleting `RenderNotes` took four tests with it, and one of them was the
only thing standing between this project and the defect the previous two
commits fixed: notes reflowed at a column, splitting a fenced command an
operator copies.

Nothing replaced it. The property is now enforced by the absence of a
transformation, which is exactly the kind of thing that comes back the next
time somebody thinks the notes look ragged in a wide terminal.

So it is asserted where the notes actually travel: `followingHarnessWith`
already lets a test rewrite the bundle before it is packed, so the vendor
declares a fenced block holding one over-long command, and the poll's
result must carry it back whole. The assertion is the entire line in one
`Contains` -- asserting on the words would pass against output that had
broken the line between them -- plus an equality check on the whole
document, so a transformation anywhere else in the path fails too.

Verified by sabotage: wrapping `result.Notes` in `ansi.Wordwrap(…, 80, "")`
at `channel.go:184` fails both assertions with the command split across
`--wait-for-` and `health`.

Not tested at the CLI layer: `update --stage` follows a channel rather than
taking a bundle path, so reaching those two lines from `clitest` would mean
a registry fixture to prove that `strings.TrimSpace` does not wrap. The
notes cross the ops boundary once, and that is where this asks.

Valid. Swapping the hand-rolled digit loop for strconv.Atoi widened what atoiSafe accepts: the loop rejected any byte that was not an ASCII digit, Atoi reads a leading sign, so COLUMNS=+80 went from falling back to the assumed width to reporting a known 80-column screen. Reproduced against the previous commit before changing it.

-1 was already covered by the n < 0 bound; only the plus needed saying. screen_test.go's malformed-value list carries +80 now, so the parity is pinned rather than asserted in a comment.

Fixed in 13b5978.

The two lines are the release-notes call sites, and the gap behind them is real: deleting RenderNotes took its four tests with it, including the only one standing between this repo and the wrapping defect fixed in 29ceddd. Nothing replaced it -- the property became the absence of a transformation.

Pinned in 051b96b where the notes actually travel: followingHarnessWith lets a test rewrite the bundle before it is packed, so the vendor declares a fenced block holding one over-long command and the poll's result must carry it back whole.

The two lines themselves stay uncovered: update --stage follows a channel rather than taking a bundle path, so reaching them from clitest would mean standing up a registry fixture to prove that strings.TrimSpace does not wrap.

Answer:
The reported regression is valid. The original parser accepted only ASCII digits, whereas strconv.Atoi also accepts a leading +, so COLUMNS=+80 changed from “unknown width” (using the fallback) to a known 80-column screen.

The fix is correct:

  • n < 0 preserves rejection of negative values.
  • strings.HasPrefix(s, "+") restores the previous rejection of positive signs.
  • strconv.Atoi still handles malformed input and overflow through its error result.
  • Adding +80 to screen_test.go pins the compatibility behavior.

No further issue with this change.

…notes

Release notes are the vendor's bytes, and every path out of `release.Notes`
ends somewhere that interprets them: `update --check` and `update --stage`
write them to stderr, and `NotesSummary` puts the first line into a
notification body that leaves the machine. Nothing filtered them, so a
bundle shipping

    \x1b]52;c;cHduZWQ=\x07

in its RELEASE.md wrote the operator's clipboard the moment they asked what
an update changes, and an OSC 0 could retitle their window.

This project already has a position on exactly this: `ops.forwardedKinds`
refuses to send `KindStepOutput` to notifiers because it is "raw
vendor-controlled output". The notes path was bypassing that position while
carrying the same kind of bytes to the same place.

Filtered at the reader rather than at the two writers, so the notifier
summary is covered by the same guard as the terminal.

Two passes, because they catch different things:

  - `ansi.Strip` removes whole escape sequences -- OSC with either
    terminator, CSI, SGR, DCS. A control-rune filter cannot do this:
    dropping the ESC alone leaves `]52;c;cHduZWQ=` on screen as text.

  - a rune pass then removes the bare C0 and C1 controls `ansi.Strip`
    leaves. The ones that matter are CR and backspace, neither of which is
    an escape sequence and either of which lets a vendor overwrite a line
    the operator has already read. Newline and tab are kept, being the two
    a note legitimately contains.

No new dependency: `charmbracelet/x/ansi` is already direct, and
`internal/ui` measures with it.

Pre-existing rather than introduced here -- reproduced identically on
`main`, where plain and JSON modes returned the raw bytes. It reaches this
PR because rich mode used to be sanitised as a side effect of rendering
through glamour, and that renderer is gone.

Reported by CodeRabbit on #72, which described it as applying "the existing
terminal-safe filtering approach". There was none; this is the first.

Both passes are sabotage-verified. The first version of the test asserted
only that no control rune survived, and *passed* with `ansi.Strip` removed
-- dropping the ESC satisfies it and leaves the payload visible. The table
now pins the payload too.

Answer:
The concern was valid: replacing the hand-rolled digit parser with strconv.Atoi changed the accepted input. Atoi accepts a leading +, so COLUMNS=+80 would previously have fallen back to the default/unknown width but would now be treated as a known 80-column terminal.

The fix preserves the old behavior:

if err != nil || n < 0 || n > 10000 || strings.HasPrefix(s, "+") {
	return 0
}

The existing negative and upper-bound checks remain intact, and screen_test.go now includes +80 among malformed values. This regression is therefore fixed and covered by a test.
