Task and section edits previously re-rendered surrounding Markdown, making rich documents vulnerable to unintended changes. This preserves unrelated source bytes, rejects unsupported edits atomically, and keeps displayed task indexes aligned with mutations, including nested and quoted checkboxes.

The change also adds:

  • Named per-file views, opt-in restoration, clear manual-save wording, and asynchronous system clipboard operations with accurate feedback.
  • Composable due/priority/section queries, idempotent done/undone commands, revision snapshots and guarded mutations, and Bash/Zsh/Fish completions. Existing JSON arrays remain compatible.
  • Structural replay, reduced failure traces, rotating scheduled campaigns, native platform checks, exact-commit release validation, checksums, provenance and verified installation.
  • Stable inline terminal frames, row-based task scrolling, visible Unicode edit cursors and correctly sized diff panels. Native POSIX CI now checks actual screens and scrollback using a pinned test-only terminal emulator.
  • Updated user documentation and archived OpenSpec requirements.
  • Review follow-ups preserve nesting during unfiltered reordering, restore recent cursors after destination views, retain blank heading references, and verify structural ownership during replay.

Validation completed locally: 1,317 tests with race detection across 11 Go packages; formatting, vet and lint; full Linux Dagger CI with real PTY contracts, CLI/structural replay, installer failure checks, Rust checks and build verification. Longer campaigns passed 36,000 TUI actions and 4,000 structural actions. The visual regressions reproduce stale headings on the prior binary and pass on the rebuilt binary, alongside the existing PTY suite and 1,000 additional simulated actions. Native macOS, Linux and Windows checks pass on this follow-up, including the new screen-and-scrollback tests on POSIX and ConPTY smoke on Windows. After review follow-ups, full local checks and race detection pass again, along with 1,000 additional TUI actions and 4,000 actions against the strengthened structural oracle. Final portable and native macOS/Linux/Windows CI passed on 44ac77c (run 34666252629).

experiments/usability/synthetic-five-person-study.json contains five invented profiles and 30 illustrative task attempts requested for study rehearsal. It has zero real participants and provides no evidence of usability improvement.

Unsupported structural edits inside blockquotes, tab-indented forms, and empty headings without source locations fail safely. Older releases without checksum manifests require the documented alternate installation route. This PR does not publish a release.

Review clarification: replacing task text replaces continuation lines in the same checkbox paragraph. LF/CRLF tests now explicitly verify this for ordinary and quoted tasks while preserving separate body blocks and reference definitions. Saved-view examples distinguish explicit/opt-in restoration from default opening, and CLI read-only rejection from temporary TUI manual-save edits.

Structural ownership assertions target the generated unique-title, checkbox-list fixtures. Duplicate-title custom traces retain baseline checks; a custom trace that outdents a checkbox beneath an ordinary non-checkbox list item can produce an oracle false positive because task parent indexes do not represent that container. This limits the test driver, not the editing operation.

CodeRabbit completed the original review at 989d31e. All seven inline findings were fixed or clarified with regression evidence and resolved; its follow-up at 44ac77c was rate-limited. The follow-up received independent code review and the local validation above.

📝 Walkthrough

Walkthrough

The change adds source-preserving Markdown editing, saved views, guarded CLI automation, cross-platform clipboard support, bounded TUI rendering, structural usage replay, and centralized release validation with checksums and provenance.

Changes

Source-preserving Markdown editing

Layer / File(s) Summary
Validated Markdown mutations
internal/markdown/*, internal/editor/*
Task and heading edits now patch source ranges, reparse results, preserve unrelated content, and reject unsafe mutations atomically.
CLI automation contracts
cmd/tdx/*, internal/cmd/*
The CLI adds filters, revision snapshots, guarded mutations, done/undone, and shell completion generation.
Saved views and TUI behavior
internal/config/*, internal/tui/*, cmd/tdx/userconfig.go
The TUI adds per-file saved views, manual-save compatibility, asynchronous clipboard operations, bounded rendering, and resize-aware navigation.
Structural usage replay
internal/usage/*, cmd/tdx-usage/*, experiments/usage/*
Structural traces now generate and replay source-preserving actions, check fidelity, and reduce failures into diagnostic artifacts.
CI, release, and installer validation
.github/workflows/*, .dagger/main.go, scripts/*, mise.toml
Portable and native checks are centralized. Releases validate exact commits and publish checksums and provenance. Installers verify artifacts before atomic replacement.
Documentation and specifications
README.md, RELEASE.md, openspec/*, experiments/usability/*
Documentation and specifications describe the new editing, automation, TUI, replay, installation, and validation contracts.

Merge Risk: 🟠 High · up to 989d3

Some Markdown edits can lose task-body content or change task hierarchy, so these correctness issues should be fixed before merge. Saved-view edge cases can also discard cursor state or prevent saving views.

Initialize Views in DefaultConfig().

Add the new configuration section to the centralized defaults. This prevents future ViewsConfig fields from silently using unintended zero-value defaults.

Proposed change
 return &UserConfig{
+    Views: ViewsConfig{
+        Restore: false,
+    },
     Theme: ThemeConfig{

As per coding guidelines, changes to cmd/tdx/userconfig.go must update DefaultConfig().

Inline comments:
In `@internal/markdown/source_edits_test.go`:
- Line 19: Remove the strings.Replace call that deletes the quoted continuation
from want in the test using UpdateTodoText, and preserve the full multiline task
body in the expected output, including the “>   continuation” line.

In `@internal/tui/update.go`:
- Line 1655: Move the saved cursor-position restoration involving
recentFiles.GetCursorPosition and m.isTodoVisible until after the new file’s
filter fields are reset and restoreSavedView() completes. Ensure visibility is
evaluated against the new file’s final filter state so valid remembered
positions are preserved.
- Line 580: Update the unfiltered reorder action in the editor flow around
editor.Move and ASTDocument.MoveTodoToPosition so moving a subtree across parent
boundaries preserves the source task depth. Configure the move to retain the
source depth or constrain its target to the same depth, while continuing to move
the complete subtree.

In `@internal/tui/views.go`:
- Around line 26-29: Update the section-reference validation used by
FileViewStore.Save and validateViews to accept empty path components produced by
ExtractHeadings for blank headings. Preserve the existing SectionRef.Path and
Occurrence indexing, and ensure blank headings remain valid when used as the
focus, folded section, or an ancestor.

In `@internal/usage/structural.go`:
- Around line 163-164: Make the structural oracle location-aware: at
internal/usage/structural.go lines 163-164, validate each protected block’s
permitted structural location rather than only comparing occurrence counts; at
lines 192-199, update the task checks to use an action-aware model that verifies
hierarchy, descendant ownership, and multiline body ownership. Preserve existing
content and task-text validation while rejecting moved blocks, detached
descendants, and bodies associated with the wrong task.

In
`@openspec/changes/archive/2026-09-12-improve-workflow-reliability/specs/saved-views/spec.md`:
- Around line 6-8: Update the “A user saves and reopens a project view” scenario
to explicitly require the user to opt in or explicitly load the saved view
before restoration occurs, and add a separate scenario asserting that opening a
project without that action does not restore the saved view by default.
- Around line 10-15: Add a separate scenario under “Compatible manual-save mode”
covering the CLI read-only contract: when a CLI mutation targets a read-only
checklist, the mutation must be rejected. Keep the existing TUI scenario focused
only on temporary edits and explicit-save behavior.
