chore(release): cut v2.4.5 "Compass" — the core reaches memory, and chooses - #441
Merged
Conversation
…chooses
Bumps the workspace to 2.4.5 and records the addressing modes, the load and
store groups, and the eight branches. RTL pinned at RustyNES_MiSTer@b01a656.
The emulation core is untouched; AccuracyCoin 141/141 (RAM decoder) and nestest
0-diff verified.
## The first cut made with bump_release.py, and it refused three times
That is the tool working. Each refusal was a real shape it did not know, and one
of them was hiding a defect.
**docs/STATUS.md** puts the codename AFTER the date in its own bold --
`v2.4.4** (2026-08-22) — **"Ignition"**, ...` -- so version and codename are not
adjacent and the adjacency test could not see it. Added as DATED_CODE.
**ROADMAP.md** reads `v2.4.4 "Ignition" released — ...`, and the classifier ate
the leading space its own CHAIN patterns were anchored on. Fixed twice: once by
not stripping the space, once by judging CHAIN on the RAW tail before anything
is removed. The first fix broke DASH, which the selftest caught immediately.
**OVERVIEW.md was confidently wrong, and had been for three releases.** It said:
The current release is **v2.4.4 "Ignition"**, which also carries the
never-tagged v2.4.0 "Concordance".
v2.4.4 carries no such thing. **v2.4.1 "Fabric"** carries v2.4.0. The sentence
was true when written at v2.4.1 and three mechanical bumps carried it forward,
saying it of v2.4.2, v2.4.3 and v2.4.4 in turn -- the exact defect the tool
exists to prevent, found because the tool refused to bump a shape it could not
classify. SECURITY.md states the same fact correctly; its "which" attaches to
Fabric.
Corrected, and the correction says what happened rather than quietly restating
the fact.
## Both post-checks were too loose and are now exact
The doubled-bold-marker check used a general regex and flagged ordinary prose --
`**the v2.1.x accuracy line**: **v2.1.0 ...` is correct markdown. It now tests
the ACTUAL anchor markers: for a marker ending in `v`, the broken form is that
marker with `**` inserted before the `v`. No false positives are possible.
The demoted-release-survives check fired on OVERVIEW.md, whose anchors are
PERIOD and BARE -- there is no description to demote there, so the old codename
legitimately disappears. It now applies only to files where a demotion was
actually performed.
A check that cries wolf on correct text is a check that gets switched off.
## New shapes
PERIOD (`... **v2.4.4 "Ignition"**.`) swaps and stops: nothing follows the
codename but punctuation, so there is nothing to demote. DATED_CODE handles the
STATUS.md form. Final classification across the 15 anchors: 5 bare, 5 dash, 2
paren, 2 chain, 1 period, 1 dated_code.
## Verification
* AccuracyCoin 141/141 (100.00%, RAM decoder), nestest 0-diff -- run, not
assumed. Non-zero test counts confirmed.
* release_anchor_audit 8/8, release_state_prose_audit 4/4,
release_notes_render_audit 2/2, cosim_manifest_audit 4/4,
libretro_info_audit 3/3.
* Release notes written through reflow.py before landing, so v2.4.5 cannot ship
with the hard-wrapped bodies v2.4.2 and v2.4.3 had to be re-published to fix.
* cargo fmt --all --check clean; markdownlint via pre-commit Passed.
* No upstream libretro PR: cadence limits those to vX.Y.0 and no licence changed.

current v2.4.5 scheduler as one-clock, every-cycle bus-access scheduling, or

the overview no longer presents the historical model as the active
implementation contract.
In `@ROADMAP.md`:
- Line 5: Update the Project Status line by removing the duplicated v2.4.4
“Ignition” release entry, leaving one v2.4.4 entry before v2.4.3 “Touchstone”
and preserving the rest of the release chain unchanged.
In `@scripts/release-automation/bump_release.py`:
- Around line 112-145: The selftest() suite must cover both the PERIOD and
DATED_CODE classification and demotion paths. Add cases for a punctuation-only
release anchor and the docs/STATUS.md dated-code format, asserting correct
classification and resulting version/codename updates without changing unrelated
self-test coverage.
In `@VERSION-PLAN.md`:
- Line 3: Remove the stale “current” labels from the v2.3.5 and v2.3.9 entries
in the release history, preserving v2.4.5 as the sole current-release anchor.
Mark those older entries as historical if needed, and ensure no conflicting
current-release claims remain in the document.

… own tooling
Every finding verified before acting. All four were real, and one I nearly
dismissed from my own truncated grep output.
## 1. The tool inserted the predecessor TWICE
`ROADMAP.md` came out of the bump reading:
on v2.4.4 "Ignition" and **v2.4.4 "Ignition"** and v2.4.3 "Touchstone"
The CHAIN handler ran two substitutions -- one anchored on `, on ` and one on
` released — ..., on ` -- and a line matching BOTH got the predecessor inserted
twice. Now exactly one `re.subn`, whose count is CHECKED: a CHAIN shape with no
`, on ` to extend is reported rather than silently left alone.
This is the tool producing confidently-wrong output, which is the thing it was
written to prevent, in a shape I had not considered. Caught by review, not by the
tool -- the tool's own output needs checking too.
## 2. PERIOD and DATED_CODE shipped without selftests
Correct: I added both shapes mid-cut and did not extend `--selftest`. A shape
with no test is a shape whose transform nobody has run. Both now covered, plus a
test asserting a chain extension names the predecessor exactly ONCE -- which
would have caught finding 1.
## 3. Two stale `(current)` labels, and I nearly waved this away
`VERSION-PLAN.md` labelled v2.3.5 "Manifest" AND v2.3.9 "Crucible" `(current)`
alongside v2.4.5. I first checked with a grep truncated at 90 columns, saw line
starts that looked innocuous, and concluded there were none -- the `(current)`
was past the cut. Reading truncated output and concluding absence is the same
mistake as reading an empty result as a pass.
The history is worth recording. **v2.3.9 already found this**: its notes say the
release table "stopped at v2.3.5, still marked `(current)`". It corrected the
anchors, left the prose label, and added a second one for itself.
`the_version_plan_table_marks_exactly_the_current_release` passes throughout,
because it checks the TABLE.
So `release_state_prose_audit` gains a second rule: `**vX.Y.Z "Codename"**
(current)` must name the workspace version. The pattern requires the bold
version-and-codename immediately before the label, which separates a real label
from prose QUOTING one -- `v2.3.5, still marked \`(current)\`` appears in both
CHANGELOG.md and v2.3.9's notes and is correct historical writing. Measured
across the tree: 5 candidates, 3 real labels, 2 quotations, and the narrow
pattern gets all five right with no escape hatch.
Demonstrated to fail on a reintroduced stale label, and fail-closed when NO
release is labelled current.
## 4. OVERVIEW.md described the retired scheduler as current
Its "Emulation Approach" said *"the scheduler advances one PPU dot at a time"* --
the five-counter dot-lockstep model that **v2.0.0 "Timebase" replaced outright**
and which is no longer a path in the code. It also claimed 51 mapper families
against the actual 174.
Same class as the v2.3.9 finding in the root ARCHITECTURE.md, and the same
mechanism as everything else in this commit: release anchors are pinned,
architecture prose is not. Corrected with the old sentence QUOTED in the
correction, so the evidence that it was wrong survives the fix.
## Also
`demoted_files` is a `set[Path]`, per the Antigravity reviewer -- the boolean
values were never `False`, so a dict was carrying information it did not have.
