The click names its own line, so it needs none of the gate the edit
keybinding needs, and for a modify/delete conflict the file it opens is
in the working tree.

The branch's opening commit belongs in PR 5, and moving it there proved
much cheaper than the note in the plan had assumed. Four more findings
needed code, two of them in gocui.

A fixup on "Show git's own diff when the renderer's can't be acted on"
would have folded two decisions into one commit: which diff to render,
and whether the content can be pointed at.

Two problems from testing PR 9: wrapLinesInDiffView governed everything
the two main panes showed, and the hint for a conflict that has to be
resolved by picking a side had a selection over it. Both are answered by
having a render say whether it holds the panel's diff.

Two bugs reported from using the stack and a third found while reproducing the
first (PR 2 round 1, PR 5 round 5, PR 8 round 1), then two more rounds as each
fix in turn was tested and found short: the pane answered "is there anything to
select here?" one screenful too early (round 6), and then took the answer over
from the commit before while it still couldn't tell (round 7).
Round 6 carries the measurements from the reported commit, which say what each
fix is worth. §8 gains the diffstat row the user has since decided to keep, and
loses the row round 7 closes.

PR 10 landed independently of the explorer removal and gained visible feedback for non-suspending editors. Capture its actual dependency, six-commit shape, pending terminal matrix, and the separately deferred click-selection behavior.

Four problems, the one root cause behind three of them, the prep refactor the
focus rule needed, and the two gaps left open. Also corrects a claim made
while the round was being scoped, that a diff renderer is re-laid-out
whenever the view width changes.

Two defects and their fixes, the testing setup that reproduces them, and

Record the four review comments the interactive pass came with, what was
decided for each, and where their fixups landed — three of them belong to
PRs 5 and 6 rather than to PR 7.

The staged-side branch grew out of it, PR 7 was rebuilt on top, and the
selection-visibility rule became a question about content rather than about
which kind of task rendered it.

It sits below PR 7, which is rebased onto it and simpler for it: which side a
pane shows is now a property of the pane, and the focus-follow rule is
symmetric.

Seventeen deviations, of which the ones that bind later work are the split
seam (PR 8's panels satisfy the extension interface), the stale timing fact
about what a refresh has done by the time it returns, and the restore's new
Done hook.
Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
Two things bind later work: a restore keeps the task reading to the end of
its input, because a rendering that has to be parsed as a diff can only be
parsed whole, and identities match through a key in which every kind of
content line collapses together - which is what lets a change that becomes
a context line still count as the same place, and a hunk header not.
The interactive pass on PR 5 found nothing to fix; refining the behaviour
of a few special cases can wait until the remaining PRs are written.
Toggling "ignore whitespace" re-renders the diff just like a context-size
change or a renderer switch does, so it belongs in PR 6 as a third
consumer. It is the first one whose anchor can vanish along with its hunk
or its whole file, which invalidates the candidate walk's reason for
stopping at the first change line; the walk goes unbounded instead, so the
restore lands on the nearest surviving line wherever in the diff that is.
And once staging happens in the main view, master's refusal to ignore
whitespace while staging no longer catches it - parked as an open question
for PR 7.
The selection commit is split in four, comments no longer point at the
staging view, and the selection commands are described and enabled only
where they apply.
The two findings from the interactive pass were folded back, which took the
loading-indicator gate to before the off-screen render — where the blanking
would otherwise arrive — and made the amend! for the origin reset
unnecessary, since the flag it needs now already exists by then.

Deviation 6 still described the TaskOpts field as the shape PR 6 should
build on while deviation 8 said it was gone, so a reader hitting 6 first
would follow a design that no longer exists. Deviation 6 now describes the
final shape and what it means for PR 6, and PR 6's own commit 1 says the
same.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The regression it found retires the PR 6 note from deviation 6, and the
race fix establishes where unrelated bugs found during this work go.

Two of them constrain later work: TaskOpts.ResetOrigin replaces the planned
LinesToRead.ResetOrigin that PR 6 was going to extend, and the screenColMax
gap PR 1 had to fix is still live on the prototype branch that later PRs
transcribe from.

The plan assumed git would never emit the records, so PR 4 skipped the
advertisement for rawGit renderers and PR 7 listed "how should rawGit
entries decide the raw fallback" as undecided, with a static args-present
rule or a well-formedness gate as the candidates. git can emit them now,
which answers that question better than either candidate: probe a rawGit
entry like any other renderer and the fallback collapses to a single rule
for every renderer type.
Record the two traps as well, since neither is visible from the outside --
the advertisement has to precede newPtyTask's no-pty early return, and the
probe's cache signature has to include the args.
Say explicitly that none of this waits on git upstream. The probe asks the
installed git what it can do, so a stock git degrades to exactly the
behaviour of a non-conforming renderer, and a fork covers the users who
want the feature if the patch is never accepted.
Probe git for the handshake like the other renderers, not for a record.
git announces itself for exactly the formats it describes, so asked with
the renderer's own arguments the handshake already answers the question,
and on empty input at that. Looking for a record was over-specified and
made git the one renderer probed differently for no reason.
The two probes that now both stand a diff up from two empty temp files
share that setup.
A rawGit diff renderer needs no pty -- git renders the diff itself, and
only a pager needs a terminal to be spawned at all -- so newPtyTask hands
that case straight to newCmdTask. But the OSC1717 advertisement was set
forty lines further down, past that early return, so git was never asked
to annotate its output and the word-diff renderer we just started
trusting emitted no records.
Set it before the branch, next to LAZYGIT_COLUMNS, which is there for the
same reason. Nothing else changes: a renderer that doesn't know the
variable ignores it, and git says nothing for the formats it doesn't
annotate, which is every format a rawGit renderer without word-diff
arguments produces.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
git now emits the diff line metadata records itself, for the word-diff
formats -- the ones whose output can't be read back from its own text,
which is the same reason we need records out of delta and difftastic. So
a rawGit renderer configured with --color-words is no longer a diff we
have to give up on: it names every row it shows, as a patched pager does.
Two things stood in the way. The probe only knew how to ask a stdin
filter or an external diff driver and reported false for anything else,
so git's own records were never looked for; and the focused main view
treated a rawGit renderer with arguments as unresolvable by definition,
re-rendering it raw whatever the probe said.
So probe git the way we will run it, with the renderer's own arguments,
and look for an actual record rather than the handshake the other probes
settle for. git annotates only some of its formats, so an installed git
that doesn't speak the protocol and arguments that select no word diff
both leave us without records, and looking for a record answers both at
once. Arguments that aren't a word diff (-U10, --stat) therefore keep
rendering raw when focused, as they did before.

We stopped updating these notes once the real work moved to
focused-main-view-notes.md and the production plan, but two things in them
have since become actively misleading rather than merely stale: they say in
five places that the protocol is content-lines-only, and they use the env
var name from two renames ago.
Mark the document historical, name the spec as the authority, and correct
§11's outcome banner in place rather than rewriting it, so the reasoning
that led to dropping `f`/`h` is still on record next to the reason it was
reversed -- which is the very cost that banner judged acceptable.
Don't touch the `EMIT_OSC1717_METADATA` spellings further down: they are
what those prototypes were built with, and the status block now says so.

The prototype was rebased onto master past #5854 (gocui mouse gestures)
and #5870 (diff-renderer config rework), so the SHAs quoted in the plan
now resolve only on the pre-rebase copy at
fold-staging-functionality-into-main-view-plan; note that in §1 and in a
dated log in §10.
PR 3 is done: #5870 landed the rename with a bigger config restructure
than planned (per-entry 'type' field, unified 'command', 'rawGit' type,
DiffRendererConfigManager). Rewrite the PR 3 section as a summary of
what landed and its consequences, key the affected decisions in PRs 4-7
off GetDiffRendererType(), add rawGit as a new case for PR 7's raw
fallback, and resolve the open question about the 'pager:' field name.
PR 10 commit 3 is superseded: the rebase dropped the press-only
modifier fix, and #5854's gesture model makes press-only insufficient
anyway; the re-implemented prototype commit carries the press-time
modifiers through the whole gesture, and the plan now points at that
shape.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A click is reported on the button press, but the press never set the
event's modifier, so a modified click (alt/shift/ctrl+click) reached
handlers stripped of its modifier, indistinguishable from a plain
click. An earlier fix for this ("Carry the keyboard modifier on mouse
click events") was lost while rebasing onto master's mouse gesture
handling (#5854) — and that work also changes what the right shape is:
it isn't enough for the modifier to ride the press alone.
Drag events and the release are delivered to the view that owns the
gesture, and bindings match modifiers exactly. If the press carried alt
but the drags carried plain ModMotion, an alt-press that no binding
consumed would start matching unmodified drag bindings mid-gesture
(drag-select), and the release of a modified gesture would look like a
plain one. So snapshot the modifiers at press time and stamp them on
every event of the gesture: the press, each drag event (combined with
ModMotion), and the release; modifier changes while the button is held
don't alter the gesture. TestMouseReleaseDoesNotKeepPressModifiers
asserted the opposite for the release and is inverted accordingly.
As before, this means a modified click that nothing binds is a no-op
rather than silently acting as a plain click.

Review clarified that "deferred" in the gap table meant "not addressed
while prototyping", not "optional". Five items are mandatory:
- IsSingleHunkForWholeFile (PR 5 commit 3): regression vs master
otherwise. Single-file-ness comes from the side panel selection; the
single-block computation's lean is patch-space over the raw diff
fetched at focus, with ReadToEnd-on-focus as the accepted fallback.
- Nav targets beyond the loaded content (PR 5 commit 6): ReadToEnd and
re-scan like openSearch; free if the above reads to end on focus.
Covers the jump-to-file menu too.
- Copy (PR 5 commit 9): reframed — copy the corresponding raw diff
lines, never the renderer's output. Dissolves the can't-tell-if-the-
renderer-preserves-the-prefix-column problem instead of solving it.
- Deleted-file MD-vs-D (new PR 7 commit 5): staging a deleted file's
entire content stages the file deletion itself.
- Renderer switch shifting the inclusion checkmarks mid-build (new
PR 8 commit 10): recompute from the new buffer at render completion.

A parallel session committed the zero-width OSC-record carrier
(fe8022827) and diagnosed the secondary patch pane's removal as broken
under difftastic: the ordinal bridge assumes displayed change lines
match the patch's change lines in order and multiplicity (difftastic
reorders d/a per hunk and collapses modification rows), and an external
diff tool over the temp trees emits the literal a/-b/ paths in its
records, so the patch-builder file lookup no-ops. PR 8 commit 7 now
prescribes the identity bridge (all payloads per row, matched against
identities from the raw temp-tree diff, k-th match -> included[k]) and
records the path-leak as an open sub-item to decide with the user; PR 4
commit 1 references the now-committed carrier, which the bridge relies
on for the d half of collapsed modification rows.
