Journey Stage 1a's core: `pmacs .` opens the directory instead of
exiting 1, and local startup stops being a second implementation of
path resolution.
`EditorState::open` now calls `EditorCore::resolve_target_buffer` --
the primitive whose own doc comment says it exists "so two
path-normalization, dedup, and hook transactions cannot drift apart",
and which local startup had never been a caller of.
`resolve_target_buffer` returns a typed `ResolvedTarget` rather than
`(BufferId, HookKind)`, with a `Directory` arm checked ahead of the
load. Without it the load runs and fails: `File::open` succeeds on a
directory and `read_to_end` returns EISDIR, which is not `NotFound`, so
the `[new file]` arm never fired.
A directory creates no buffer. It dispatches a resolver chain: the
short-circuit `path.open-directory` hook, which no builtin subscribes
to, and then `pmacs.path.directory_handler`, which dired defaults. The
split is forced rather than chosen -- hook callbacks only append and
builtins load before init.lua, so a subscribing builtin would always
claim before any user listener could run. A raising listener stops the
chain and suppresses the fallback.
The listing is async and the daemon bootstrap is not, so the whole
post-await commit runs inside a new `pmacs.window.commit_to`: it
validates the destination -- frontend live, window live, buffer
unchanged, window replaceable -- BEFORE invoking its callback, then
scopes the acting frontend for its extent. Validating at display time
would be four dired mutations too late.
That scope is deliberately not `InteractiveCommandOrigin`, which does
not reach the core-ambient APIs and is authenticated user-command
authority a background continuation must not acquire.
The dedication rule is extracted into one `window_accepts_buffer`
shared by exact display, the display probe, and the new preflight, with
`incoming: Option<BufferId>` -- `None` means "the replacement does not
exist yet" and refuses a dedicated window.
`display_file` keeps its directory-is-an-error contract and does not
enter the chain; find-file's accept arm depends on it.
Framing: docs/journey-stage1a-framing.md rev 5 (Q#JR1-JR15).
Pulls a set of planned V0.2 prerequisites forward to ship in v1.0,
plus the clean audit-review round over that work.
V0.2-prereq implementations (documented promotions, not M11
surprises; operator raised the v1.0 public-API ceiling to absorb
them — see V0.2-PREREQUISITES.md "v1.0 pull-forward"):
- CC-1: `bypass_intercept` opts on buffer insert/delete/replace —
skips the Lua intercept chain only; preserves the same-buffer
re-entry guard, undo/dirty bookkeeping, view notifications, and
CRDT broadcast queueing.
- CC-2: `pmacs.buffer.on_removed(buf, cb)` + idempotent `:remove()`
handle; buffer-local keymaps pruned on removal. Fires for both
`pmacs.buffer.remove` and `.kill` (incl. interactive C-x k);
callback errors logged to *errors* without failing the removal.
- SP-4: `pmacs.buffer.from_file`.
- SP-5: `pmacs.fs.watch` (polling; `:cancel()`/`:is_cancelled()`).
- SP-7: `pmacs.async.yield_to_next_tick` (worker-free next-tick
yield); outline-aggregate repaint now uses it instead of
workers.sleep(0):await(), pinning propagation to one async tick.
- SP-1: `pmacs.editor.move_to_line` (0-based, clamps out-of-range).
- SP-6: `pmacs.outline.query` published by pmacs-outline.
- SP-3: audit rule 15 `reach-around-require-field` (Info).
- CC-3: runtime API-availability documented (docs-only).
Clean audit-review round (M10.11 framing stop-condition pass):
- Finding 1 (fixed): clippy needless_raw_string_hashes blocked
`clippy -D warnings` on both lanes; raw-string delimiter fixed.
- Finding 2 (fixed): fs_watch acceptance test was racy — the
`pending == 1` gate could not distinguish the in-flight baseline
stat from the steady-state poll sleep, so under load the mutation
raced the baseline (~1/3 fail in the default lane). Rewritten to
re-emit a distinct change each pump iteration; 6/6 on the
previously-failing invocation.
- Finding 3 (fixed): documented fs.watch's async-baseline startup
window and size+mtime-granularity detection limit.
- Finding 4 / SP-8 (logged, non-blocking, out of diff): a
pre-existing PTY-lifecycle test timing flake under severe CPU
oversubscription; src/process.rs untouched here.
CC-1's opts-extension-counts question resolved explicitly
(consistent treatment: counted; ceiling raised to fit).
Gate at normal load, both lanes: fmt clean; clippy --all-targets
-D warnings clean; non-crdt lib 1223/0; crdt lib 1377/0;
m8_1/m8_9/m8_10 green.
Not in scope here: v1.0 CHANGELOG body, version bump, the M10.11
Finding-4 (reattach undo) user-facing artifact, and the recorded
two-laptop manual acceptance — tracked as the remaining v1.0 steps.
.gitignore: M*-FRAMING.md added to the internal-only block for
consistency with the M*-AUDIT.md / M*-SHIP-GATE.md siblings.
