### Surface Stress Test — permanent fixture, found a real bug (2026-08-02)
|
||||
|
||||
`ART-STRESS-TEST ( seed reps -- )` (`capsules/artemis/init.4th`, blocks 4160–4173) is a permanent, on-demand exercise of
|
||||
the block-storage path across the whole data pool: `reps` distinct random blocks (coprime-stride walk, collision-free,
|
||||
never touches anything already allocated by someone else), written, then verified after all writes complete so real
|
||||
cache-eviction traffic gets forced through both caching layers. Every trial emits a `[ARTSTRESS]`-tagged CSV row to the
|
||||
serial log (`HEADER`/`SUMMARY` markers make a truncated run unmistakable). Invoke as
|
||||
`ART-STRESS` (fixed seed, 50 reps) or `<seed> <reps> ART-STRESS-TEST`. Not wired into the boot sequence — block 4170
|
||||
carries the entry point commented out (`\ ART-STRESS`), same disable-by-default convention as
|
||||
`ACL.4th`'s self-activation toggle, so ordinary boots pay nothing for it.
|
||||
|
||||
Its first completed run found a real, pre-existing data-corruption bug on amd64: 25 of 50 trials (50%) returned the
|
||||
wrong byte pattern. Root cause, confirmed by source review and fixed in `src/word_source/block_words.c`
|
||||
(not Artemis-specific — this is shared block-subsystem plumbing every VM using `BLOCK`/`UPDATE`/`FLUSH` goes through):
|
||||
the VM-level "window" cache (`vm->blk_vm_cbuf[]`) stores a raw pointer directly into one of the block-subsystem's eight
|
||||
`cache_slot_t` devblock-cache entries (`block_subsystem.c`). That cache's own FIFO eviction relocates entries via
|
||||
struct-copy (`slot->cache[i] = slot->cache[i+1]`) once more than eight distinct devblocks are touched in one VM
|
||||
session — the *addresses*
|
||||
of `cache[0..7]` never move, but what they hold does, silently, aliasing any window pointer captured before the shift.
|
||||
No prior test had ever touched enough distinct devblocks in one session to trigger it. Fixed by re-resolving the buffer
|
||||
pointer by logical block number (`blk_get_buffer`)
|
||||
immediately before every write-through-cache-pointer operation in
|
||||
`block_word_update`, `blk_vm_evict`, and `blk_vm_flush_all`, instead of trusting a pointer captured earlier — confined
|
||||
to the consumer side, no change to the block subsystem's cache architecture. Independent of, and predates, the
|
||||
`BLK-CONFIRM-FORMAT` fix above; neither touches the other's code path. Re-verified 50/50 on amd64, aarch64, and riscv64
|
||||
after the fix. Full write-up with hypothesis-tested analysis (a naive "consecutive writes fail together" reading did not
|
||||
survive a formal runs test — see the report for what did and didn't hold up):

|
||||
|
||||
## The Pivot This Document Reflects
|
||||
|
||||
Console was first framed as "wrap the existing bitmap/VT100 framebuffer driver in a 4th Tripod VM." That framing is
|
||||
superseded. The framebuffer is now treated as a **drawing fabric**: full-color, Cartesian-addressed, rasterized-vector —
|
||||
not a character-cell bitmap terminal. Text is one thing drawn on the fabric, not a special case. Rationale (Captain Bob,
|
||||
verbatim intent): everything in the eventual GUI is going to be drawn anyway, so the console should be drawn the same
|
||||
way from the start rather than built on a bitmap terminal that gets thrown away later.
|
||||
|
||||
The existing `src/starkernel/hal/framebuffer.c` (raw UEFI GOP pixel plotting) is still the right low-level substrate —
|
||||
that part is reused. `font_8x16.c` and
|
||||
`vt100.c` (the bitmap-cell VT100 emulator built on top of it) are what's being superseded; see Open Decisions below for
|
||||
their fate.
|
||||
|
||||
---
|
||||
|
||||
## Language Constraint — Non-Negotiable
|
||||
|
||||
All Console implementation is in StarForth dialect ONLY, with the same narrow exception every other Tripod VM has: raw
|
||||
hardware access (the actual pixel write into GOP framebuffer memory) is C, registered directly as Forth primitives —
|
||||
exactly how `BLOCK`/`UPDATE`/`FLUSH`/`RANDOM`/`SEED` already work. Everything above that raw pixel-write boundary —
|
||||
glyph composition, cursor logic, dirty-cell tracking, VT100 semantics, fonts — is StarForth.
|
||||
|
||||
C99 beyond that narrow hardware boundary is forbidden unless explicitly blocked in StarForth AND explicit written
|
||||
permission is given by Captain Bob for that specific construct. "I could not figure out how to do this in StarForth" is
|
||||
not permission. Ask first. Wait for the answer.
|
||||
|
||||
---
|
||||
|
||||
## When Stuck — Non-Negotiable
|
||||
|
||||
If you are stuck, STOP.
|
||||
|
||||
Do not confabulate. Do not invent dictionary words that do not exist. Do not fabricate primitives. Do not guess at
|
||||
behavior. Do not work around the problem silently.
|
||||
|
||||
STOP. Report exactly what is blocking you. Wait for instruction.
|
||||
|
||||

|
||||
|
||||
## What Console Is
|
||||
|
||||
Console is the fleet's fourth leg — Quadrupod, not Tripod. A real StarForth VM, spawned by Hera, participating in fleet
|
||||
K≡1.0 like Hermes and Artemis. Its contract:
|
||||
Console owns the drawing fabric (the framebuffer) and, in a later phase, keyboard input. It renders. It does not route
|
||||
messages (Hermes), does not own persistent storage (Artemis), and does not make VM lifecycle decisions (Hera).
|
||||
|
||||
Mythological name: **not yet chosen.** Candidates raised (Argus, Iris, Hestia) were not settled on. Do not pick one
|
||||
unilaterally when implementation starts — ask Captain Bob. This document uses "Console" as a working label until named.
|
||||
|
||||
---
|
||||
|
||||
## Coordinate System
|
||||
|
||||
True Cartesian: **origin bottom-left, Y increases upward.** This is a firm decision, not a placeholder. The
|
||||
framebuffer's native memory layout is top-left origin, Y-down (standard raster convention) — every drawing primitive
|
||||
that touches the framebuffer must apply the Y-flip transform. Get this at the lowest primitive layer so nothing above it
|
||||
ever has to think about it again.
|
||||
|
||||
---
|
||||
|
||||
## Primitive Layer — C, registered directly as Forth words
|
||||
|
||||
Raw, hardware-touching, absolute-coordinate. Not turtle/relative — see Font & Pen Layer below for why the split falls
|
||||
here.
|
||||
|
||||
- `PLOT ( x y color -- )` — set one pixel (post Y-flip transform)
|
||||
- `LINE ( x1 y1 x2 y2 color -- )` — Bresenham line between two absolute points
|
||||
|
||||
Absolute coordinates were chosen deliberately: the long-term direction (wireframes — triangles/quadrangles, eventually
|
||||
textured/shaded) is fed by projected vertex data, which is naturally absolute per-vertex, not relative turtle deltas.
|
||||
Building the hardware boundary around absolute coordinates means the eventual triangle-fill / texture-sample primitives
|
||||
extend this layer instead of fighting it.
|
||||
|
||||
**Performance principle — non-negotiable:** the actual per-pixel work (Bresenham walk, eventually triangle
|
||||
rasterization, texture sampling) must live in this C layer, compiled. Forth orchestrates — decides what to draw and
|
||||
when — but never walks pixels one at a time through the interpreter. This is the same C-does- hardware /
|
||||
Forth-does-policy split every other Tripod VM already uses; it is not a new rule invented for Console, just applied
|
||||
here.
|
||||
|
||||
Known unknown: actual achievable frame rate. Feasible in principle (this is how every pre-GPU software-rasterized engine
|
||||
worked), but unmeasured, and QEMU TCG (the only acceptance environment per `.claude/CLAUDE.md`) will be meaningfully
|
||||
slower than real hardware for CPU-emulated per-pixel work. Do not assume a frame-rate target without measuring on the
|
||||
actual target environment first.
|
||||
|
||||
---
|
||||
|
||||
## Font & Pen Layer — StarForth, composable
|
||||
|
||||
Fonts are not a C data table. Each glyph is a StarForth word, e.g.
|
||||
`GLYPH-A ( x y -- )`, expressed as a short sequence of pen strokes relative to the glyph's origin — a small pen DSL
|
||||
(`STROKE dx dy`, pen up/down, within a unit em-box) that resolves down to calls into the absolute `LINE` primitive. This
|
||||
is deliberately hackable: a font is just another `.4th` capsule, content-addressed and hash-verified exactly like every
|
||||
other capsule in this system. Swap the capsule, get a different typeface. No new loading mechanism — the existing
|
||||
capsule system already does this.
|
||||
|
||||
This does not fight the performance principle above: glyph composition is a handful of word dispatches (5–15 strokes per
|
||||
character), not per-pixel work. The expensive part — actually writing pixels — stays in the C `LINE` primitive
|
||||
regardless of how the glyph was authored. Combined with heat-driven redraw (below), most glyphs aren't recomposed most
|
||||
ticks anyway.
|
||||
|
||||
A thin turtle/pen convenience layer (position + heading state, `FORWARD`/`RIGHT`/
|
||||
`PENUP`/`PENDOWN`) may be built on top of the same absolute `LINE` primitive for generative drawing use cases. It is
|
||||
StarForth-only, costs nothing at the C layer, and does not change the hardware-boundary decision to stay absolute.
|
||||
|
||||
Phase 1 requires the **full printable-ASCII stroke-glyph table**, not a subset — a VT100-equivalent terminal needs to
|
||||
render arbitrary text from day one. A narrower subset only made sense as a pipeline smoke test in isolation, which is no
|
||||
longer the goal.
|
||||
|
||||
---
|
||||
|
||||
## Heat-Driven Redraw Model
|
||||
|
||||
Screen redraw is dirty-cell tracking, expressed in the same compudynamic vocabulary as everything else in this system —
|
||||
not decorative, it's the actual mechanism.
|
||||
|
||||
- Each screen cell carries a heat value, structurally the same idea as `BLK-HEAT`
|
||||
for Artemis's data blocks.
|
||||
- A cell goes hot (`Q.1`) the moment its content changes.
|
||||
- Console's own tick (driven off Hera's fleet heartbeat, same pattern as
|
||||
`ART-TICK`) scans for hot cells only.
|
||||
- For each hot cell, Console redraws it via the glyph/`LINE` primitives — and that redraw **is** the reap event. Heat
|
||||
goes to zero because the work got done, not because of a time-based decay curve like Artemis blocks or Hermes
|
||||
messages.
|
||||
- Cells at K=0 are skipped entirely this tick — untouched pixels, no wasted work.
|
||||
|
||||
This cell-heat contributes to Console's share of fleet K, same as every other compudynamic object in the system. Reap
|
||||
(redraw-to-zero) must rebalance K correctly, same invariant every other VM already honors.
|
||||
|
||||
---
|
||||
|
||||
## Immediate Goal
|
||||
|
||||
Scope for the first real implementation pass. Nothing past this section is authorized to build yet.
|
||||
|
||||
**The target:** a VT100-equivalent interactive terminal, rendered entirely through the vector fabric described above
|
||||
(not the old bitmap driver), with:
|
||||
|
||||
1. Console spawns as the fleet's 4th leg under Hera's birth protocol, joins fleet K≡1.0 like Hermes and Artemis.
|
||||
2. Full printable-ASCII stroke font, composable/StarForth-authored, loaded as a capsule.
|
||||
3. Cursor positioning, basic scrolling, and enough VT100 semantics to be a usable terminal — the same functional bar the
|
||||
current bitmap `vt100.c` already clears, just achieved through the new fabric instead.
|
||||
4. Heat-driven redraw — only changed cells get rasterized per tick.
|
||||
5. Text arrives at Console the same way everything else moves between Tripod VMs:
|
||||
via Hermes. Console does not invent a second message-passing mechanism.
|
||||
|
||||
**Explicitly out of scope for this phase:** keyboard input (see Future Material — there is no keyboard driver anywhere
|
||||
in this codebase yet, this is a separate, substantial piece of work), double buffering (open decision, see below), the
|
||||
wireframe/textured/shaded GUI vision (that's the reason the fabric is built this way, but building it is a different,
|
||||
later phase).
|
||||
|
||||
---
|
||||
|
||||
## Open Decisions — must be settled before or during implementation
|
||||
|
||||
1. **Mythological name.** Not chosen. Ask Captain Bob before implementation starts.
|
||||
2. **Fate of `font_8x16.c` / `vt100.c`.** Kept only for pre-Console boot diagnostics (before Console VM is alive to take
|
||||
over), or retired outright once the fabric is proven? Not decided.
|
||||
3. **Double buffering.** Direct framebuffer writes will tear once Console is doing partial redraws every tick instead of
|
||||
static boot text. Cheaper to decide now than to retrofit through every draw call later. Not decided.
|
||||
4. **Actual frame-rate/performance numbers.** Unmeasured. Do not commit to a real-time target without benchmarking on
|
||||
real hardware and under QEMU TCG separately — they will differ meaningfully.
|
||||
|
||||
---
|
||||
|
||||
## FUTURE MATERIAL — Not In Scope
|
||||
|
||||
Everything below is real direction, preserved intentionally, and is **not** part of the Immediate Goal above. Do not
|
||||
build any of this without Captain Bob explicitly reopening it — same rule ARTEMIS.md and TRIPOD.md already hold their
|
||||
own future chapters to.
|
||||
|
||||
### Full wireframe GUI
|
||||
|
||||
Triangles/quadrangles from projected vertex data, applied textures and shading, anti-aliased/high-resolution appearance
|
||||
("not blocky") even at small polygon sizes. Visually in the spirit of vector-display arcade games (Asteroids),
|
||||
rasterized in software onto the linear framebuffer — no GPU, no hardware acceleration available on this platform. The
|
||||
absolute-coordinate `PLOT`/`LINE` primitive layer is designed so triangle-fill/texture-sample primitives extend it later
|
||||
rather than replacing it.
|
||||
|
||||
### Keyboard input
|
||||
|
||||
No driver exists anywhere in this codebase today. PS/2 8042 controller is the pragmatic first target — QEMU supports it
|
||||
cleanly. USB HID through the existing virtio/PCI stack is a materially bigger lift and should come later, if at all.
|
||||
`M8: REPL keyboard input` in the top-level roadmap has been "planned, not started"
|
||||
for the life of this project; this is the same gap.
|
||||
|
||||
### Interactive REPL on the framebuffer
|
||||
|
||||
Once keyboard input exists, point a real interactive REPL loop at Console instead of (or alongside) the serial `ok>`.
|
||||
This is the piece that actually starts to make the system feel like an operating system rather than a kernel with a
|
||||
serial console. Depends entirely on keyboard input landing first.
|
||||
|
||||
### Multi-window / multi-session
|
||||
|
||||
Not discussed in depth. Flagged here only so it isn't forgotten — if the fabric approach pans out, multiple independent
|
||||
drawing regions/sessions is a natural next question once single-console VT100-equivalent behavior is solid.

\noindent
|
||||
A newly written stress test for Artemis, LithosAnanke's block-storage VM,
|
||||
found a real data-corruption bug on its first completed run: 25 of 50
|
||||
random-block write/verify trials (50\%) returned the wrong byte pattern on
|
||||
amd64. The test's own recorded data ruled out its block-selection logic as
|
||||
the cause (no duplicate logical block numbers or devblocks among the 50
|
||||
trials). Four exploratory hypotheses were then tested formally rather than
|
||||
read off a chart: a Wald--Wolfowitz runs test found no significant serial
|
||||
clustering of failures by write order ($p=1.00$); a direct rank test
|
||||
against write order agreed ($p=0.715$); sibling position within a shared
|
||||
4\,KiB devblock showed no association ($p=0.674$); but logical block
|
||||
number itself showed a significant association with outcome
|
||||
($p<0.001$, Wilcoxon), an effect specific to this run's fixed random seed
|
||||
that this report does not claim generalizes. None of these exploratory
|
||||
tests, on their own, identify a mechanism. Root cause was instead found by
|
||||
source code review: a stale raw-pointer alias held by the VM-level block
|
||||
window cache (\texttt{src/word\_source/block\_words.c}) into a slot of the
|
||||
block-subsystem's own eight-entry devblock cache
|
||||
(\texttt{src/block\_subsystem.c}), which the subsystem's own FIFO eviction
|
||||
relocates via struct-copy without informing the window cache holding a
|
||||
pointer into it. No prior test had ever touched enough distinct blocks in
|
||||
one VM session to trigger it, and the defect is independent of unrelated
|
||||
same-day work on Artemis's disk-format detection. A three-site fix --
|
||||
re-resolving the buffer pointer by logical block number immediately before
|
||||
every write-through-cache-pointer operation, rather than trusting a
|
||||
pointer captured earlier -- eliminates the defect without altering the
|
||||
block subsystem's cache architecture. This is confirmed by the strongest
|
||||
result in this report: a two-proportion test of pre-fix versus pooled
|
||||
post-fix (three architectures, 150 trials) pass rate rejects the null
|
||||
hypothesis of no change at $p = 2.04\times10^{-19}$. Re-verification:
|
||||
50/50 on amd64, 50/50 on aarch64, 50/50 on riscv64, zero mismatches. The
|
||||
test itself is now a permanent, on-demand fixture in the Artemis capsule
|
||||
(\texttt{ART-STRESS} / \texttt{ART-STRESS-TEST}), disabled by default so
|
||||
it does not add to ordinary boot time.
|
||||
\end{abstract}
|
||||
|
||||
\section{Motivation}
|
||||
|
||||
Prior to this investigation, every automated exercise of Artemis's
|
||||
block-storage path -- \texttt{ART-WRITE-TEST}, \texttt{ART-READ-TEST},
|
||||
\texttt{ART-SELF-TEST} -- touched exactly one data block per run. That is
|
||||
sufficient to prove the alloc/persist/free lifecycle works in isolation,
|
||||
but it never puts real pressure on the underlying caches: the
|
||||
block-subsystem's own eight-slot devblock cache
|
||||
(\texttt{DISK\_CACHE\_SLOTS} in \texttt{block\_subsystem.c}) and the
|
||||
VM-level ``window'' cache used by the \texttt{BLOCK}/\texttt{BUFFER}/
|
||||
\texttt{UPDATE} words (\texttt{block\_words.c}) were never both forced to
|
||||
evict within a single VM session.
|
||||
|
||||
The request behind this work was explicit: give the mounted virtual disk
|
||||
a real workout -- real FORTH doing real writes, scattered randomly across
|
||||
its entire surface area, on the premise that a test never exercised
|
||||
before was the most likely place to find a crack.
|
||||
|
||||
\section{Test Design}
|
||||
|
||||
\texttt{ART-STRESS-TEST~( seed reps -- )} performs a two-phase write/verify
|
||||
cycle against \texttt{reps} distinct, randomly chosen blocks drawn from the
|
||||
full 22\,998-block Artemis data pool (logical block numbers 3076--26073):
|
||||
|
||||
\begin{enumerate}[nosep]
|
||||
\item \textbf{Pick.} A coprime-stride walk over the index space
|
||||
(stride and starting offset both drawn via \texttt{RANDOM}, stride
|
||||
forced odd and checked against the two odd prime factors of 22\,998 =
|
||||
$2 \times 3 \times 3833$) selects a block index guaranteed not to repeat
|
||||
within the run, skipping past any index already allocated by something
|
||||
else so the test never overwrites pre-existing legitimate data.
|
||||
\item \textbf{Write.} The block is allocated through the same path
|
||||
\texttt{BLK-ALLOC} uses internally (free-map bit set, heat born hot),
|
||||
filled with a trial-derived byte pattern, and persisted.
|
||||
\item \textbf{Verify.} After \emph{all} \texttt{reps} writes complete --
|
||||
forcing real eviction/reload traffic through both cache layers -- each
|
||||
block is re-fetched and its content checked against what was written.
|
||||
\item \textbf{Record.} Every trial, pass or fail, emits one
|
||||
\texttt{[ARTSTRESS]}-tagged CSV row (trial, logical block number,
|
||||
pattern, result) to the serial log, plus a \texttt{HEADER} marker at
|
||||
start and a \texttt{SUMMARY} marker at completion -- if a run is
|
||||
killed mid-way, the summary marker is simply absent, making a
|
||||
truncated dataset unmistakable rather than silently partial.
|
||||
\item \textbf{Clean up.} Every block the run allocated is freed.
|
||||
\end{enumerate}
|
||||
|
||||
The design deliberately treats this as an offline data-collection fixture,
|
||||
the same posture as the existing DoE campaign: correctness of the
|
||||
collected data matters more than run speed, and \texttt{ART-K-TOTAL} is
|
||||
recorded before and after (informational only -- it is not a pass/fail
|
||||
gate, since a background heartbeat decay tick during a long run is
|
||||
expected behavior, not a defect).
|
||||
|
||||
The first completed run, 50 trials on amd64 with seed 424242 (the fixed
|
||||
seed \texttt{ART-STRESS} uses), returned \textbf{25 passes and 25
|
||||
failures} -- an exact 50\% split (Figure~\ref{fig:pass-rate}, bottom bar).

||||

|

|
||||
\section{Statistical Analysis}
|
||||
|
||||
\textbf{Premise.} A 50\% failure rate on the first completed run of a new
|
||||
test is consistent with at least three distinct explanations, which are
|
||||
not mutually exclusive: (a) a bug in the test's own block-selection logic
|
||||
producing duplicate or colliding picks, (b) a genuine but narrow defect
|
||||
tied to a specific access pattern (e.g.\ cache eviction timing), or (c) a
|
||||
defect tied to a specific region of the disk. Duplicate logical block
|
||||
numbers and duplicate devblocks among the 50 trials were checked directly
|
||||
against the recorded data and neither was found, ruling out (a) as stated.
|
||||
The hypotheses below were formulated to distinguish (b) from (c) before
|
||||
committing to a source-code investigation in either direction.
|
||||
|
||||
All tests below use the pre-fix amd64 run's own recorded trial data
|
||||
(\texttt{runs/amd64\_buggy.csv}, $n=50$, under
|
||||
\texttt{experiments/artemis\_stress/}) and were computed by the analysis
|
||||
script \texttt{analyse\_artemis\_stress.R} in that same directory; no
|
||||
number in this section is hand-typed.

failures -- trials 24, 25, 26 failing together, then 27 and 28 passing,

then 29, 30, 31 failing again. A formal runs test does not support that

reading: 26 runs were observed against 26.0 expected under a purely

random ordering with the same 25/25 split ($z=0.000$). A direct Wilcoxon
|

test of trial index by outcome agrees ($p=0.715$). \textbf{The naive

``recently written survives, long ago fails'' cache-timing story is not

supported by this data} and should not be asserted as the mechanism.

\textbf{H2 and H2b -- an unresolved location effect, specific to this
|

seed.} Logical block number \emph{does} show a significant association
|
||||
with outcome ($p<0.001$): failing trials in this run had a lower mean LBN
|
||||
($\bar{x} \approx 11{,}355$) than passing trials ($\bar{x} \approx
|
||||
18{,}401$). This was not expected, and this report does not have a causal
|
||||
explanation for it -- the diagnosed mechanism (Section~\ref{sec:rootcause})
|
||||
is a pointer-aliasing defect tied to cache eviction \emph{order}, and
|
||||
this section's H1/H1b results (above) show no association with order in
|
||||
this run, which is in tension with a simple location-driven story. The most defensible
|
||||
reading is that \texttt{ART-STRESS-TEST}'s seed (424242) is fixed, so the
|
||||
specific sequence of devblock accesses -- and therefore which window-cache
|
||||
pointers go stale -- is a deterministic, reproducible function of that
|
||||
seed for this run, and some property of that one sequence happens to
|
||||
correlate with LBN value without implying that block number is, in
|
||||
general, a causal factor. Sibling position within a shared devblock shows
|
||||
no association ($p=0.674$), which rules out the simplest region-based
|
||||
explanation (three data blocks per 4\,KiB devblock, checked directly).
|
||||
This finding is reported rather than smoothed over; it does not change
|
||||
the fix or its verification, and Figure~\ref{fig:coverage}'s lower panel
|
||||
shows no visually obvious sub-region concentration despite the test
|
||||
result.

|
||||
|
||||
\textbf{Conclusion of this section.} None of H1, H1b, or H2/H2b, singly
|
||||
or together, identify a mechanism -- they narrow the search (ruling out
|
||||
write-order clustering and sibling-position effects as the story) without
|
||||
answering the question. Root cause was found by source code review,
|
||||
described next; H3, in Section~\ref{sec:verification}, is what actually
|
||||
confirms the diagnosis, by showing the identified defect's fix removes
|
||||
the failures entirely and unambiguously.
|
||||
|
||||
\section{Root Cause}
|
||||
\label{sec:rootcause}
|
||||
|
||||
LithosAnanke's block storage stacks two independent caches:
|
||||
|
||||
\begin{enumerate}[nosep]
|
||||
\item \textbf{The block-subsystem's devblock cache}
|
||||
(\texttt{blk\_dev\_slot\_t.cache[DISK\_CACHE\_SLOTS]}, eight entries,
|
||||
\texttt{block\_subsystem.c}). When full and a ninth distinct devblock
|
||||
is needed, \texttt{cache\_get\_slot()} evicts by shifting the entire
|
||||
array down one position via struct assignment:
|
||||
\begin{lstlisting}[language=C]
|
||||
(void) cache_writeback(slot, &slot->cache[0]);
|
||||
for (int i = 0; i < DISK_CACHE_SLOTS - 1; i++)
|
||||
slot->cache[i] = slot->cache[i+1];
|
||||
\end{lstlisting}
|
||||
The \emph{addresses} of \texttt{cache[0..7]} never move; what they
|
||||
\emph{hold} does, silently.
|
||||
\item \textbf{The VM-level window cache}
|
||||
(\texttt{vm->blk\_vm\_cbuf[BLK\_VM\_SLOTS]}, \texttt{block\_words.c}),
|
||||
used by \texttt{BLOCK}/\texttt{BUFFER}. When a block loads, it stores
|
||||
the \emph{raw pointer} \texttt{blk\_get\_buffer()} returns --
|
||||
\texttt{c->data + pack * BLK\_FORTH\_SIZE}, pointing directly into one
|
||||
of the eight \texttt{cache\_slot\_t} structs above.
|
||||
\end{enumerate}
|
||||
|
||||
Nothing informs layer 2 when layer 1 shifts its array. Once more than
|
||||
eight distinct devblocks have been touched in one VM session, a
|
||||
previously-captured window pointer can point at memory that now belongs
|
||||
to a completely different devblock, with no error and no signal --
|
||||
just wrong data on the next read or write through it. No prior test ever
|
||||
touched enough distinct devblocks in a single session to trigger this;
|
||||
the surface stress test's fifty scattered writes was the first thing
|
||||
that did. This mechanism does not, on its face, predict a dependency on
|
||||
LBN value rather than access pattern, which is consistent with this
|
||||
report's inability to causally explain the H2 result above -- the exact
|
||||
per-trial trigger condition is a complex function of window-slot reuse
|
||||
and devblock-array-shift interleaving that this investigation did not
|
||||
instrument further, since it is not required to confirm or fix the
|
||||
defect. The defect is independent of, and predates, unrelated same-day
|
||||
work on Artemis's disk-format detection (\texttt{BLK-CONFIRM-FORMAT}) --
|
||||
none of that work touches \texttt{cache\_get\_slot} or the window-cache
|
||||
functions.
|
||||
|
||||
\section{Fix}
|
||||
|
||||
Three call sites in \texttt{block\_words.c} wrote through the stored
|
||||
window pointer before calling \texttt{blk\_update()}: \texttt{block\_word\_update}
|
||||
(backing the Forth word \texttt{UPDATE}), \texttt{blk\_vm\_evict}'s
|
||||
all-slots-dirty fallback, and \texttt{blk\_vm\_flush\_all} (backing
|
||||
\texttt{FLUSH}/\texttt{SAVE-BUFFERS}). Each now re-resolves a
|
||||
\emph{guaranteed-current} pointer by logical block number immediately
|
||||
before use:
|
||||
|
||||
\begin{lstlisting}[language=C]
|
||||
uint8_t *fresh = blk_get_buffer((uint32_t) blk, 1);
|
||||
if (!fresh) { vm->error = 1; return; }
|
||||
memcpy(fresh, vm->memory + base, BLOCK_SIZE);
|
||||
vm->blk_vm_cbuf[s] = fresh; /* keep the window's own copy in sync */
|
||||
\end{lstlisting}
|
||||
|
||||
\texttt{blk\_get\_buffer()} internally calls \texttt{cache\_load\_devblock()},
|
||||
which correctly resolves (or reloads) whichever slot currently holds that
|
||||
logical block number, however the array has shifted since the window
|
||||
pointer was first captured. The fix is confined entirely to the consumer
|
||||
side and does not alter the block subsystem's cache architecture: never
|
||||
trust a raw cache pointer across an operation boundary where the producer
|
||||
may have invalidated it -- ask for the current one again, right before
|
||||
using it.
|
||||
|
||||
\section{Verification}
|
||||
\label{sec:verification}
|
||||
|
||||
The fix was verified by re-running the identical stress test (same seed,
|
||||
same 50-trial coprime-stride sequence) on all three supported
|
||||
architectures.
|
||||
|
||||

|
||||

|
||||
|
||||
Pooling the three post-fix runs against the pre-fix run and testing
|
||||
$H_0:$ ``pre-fix and post-fix trials share the same true pass rate''
|
||||
with a two-proportion test rejects $H_0$ at
|
||||
$p = 2.04\times10^{-19}$ (Table~\ref{tab:hypotheses}, H3; 95\% CI on the
|
||||
difference in pass rate: $[-0.652, -0.348]$). This is the definitive
|
||||
result in this report: unlike H1/H1b/H2/H2b, which narrow the search
|
||||
space without identifying a mechanism, H3 directly confirms that the
|
||||
change made in Section 5 -- and only that change -- accounts for the
|
||||
difference between a 50\% and a 100\% pass rate, consistently, across
|
||||
three independent instruction-set architectures.
|
||||
|
||||
All three post-fix architectures also completed the standard acceptance
|
||||
boot to \texttt{ok>} with the fix in place, and Hera's dictionary-hash
|
||||
parity across amd64 and aarch64 matched exactly for identical capsule
|
||||
content, confirming the fix does not disturb cross-architecture
|
||||
determinism.
|
||||
|
||||
\section{Disposition}
|
||||
|
||||
The surface stress test is now a permanent fixture of the Artemis capsule
|
||||
(\texttt{capsules/artemis/init.4th}, blocks 4160--4173), invocable on
|
||||
demand as \texttt{ART-STRESS} (fifty trials, fixed seed) or
|
||||
\texttt{<seed> <reps> ART-STRESS-TEST} for a custom run. It is not wired
|
||||
into the automatic boot sequence -- block 4170 carries the entry point
|
||||
commented out (\texttt{\textbackslash\ ART-STRESS}), matching the same
|
||||
disable-by-default convention already used by \texttt{ACL.4th}'s
|
||||
self-activation toggle, so ordinary boots pay no extra time for it. A
|
||||
future maintainer can uncomment that one line to run it automatically, or
|
||||
invoke it manually from the console at any time. The unresolved H2
|
||||
finding (Section 4) is left as an open question for a future
|
||||
investigation with additional cache-state instrumentation, not as a
|
||||
loose end in the fix itself, which H3 confirms is complete.

Artemis surface stress test -- hypothesis tests
|
||||
=================================================
|
||||
|
||||
H1 -- pre-fix failure clustering (Wald-Wolfowitz runs test)
|
||||
H0: pass/fail outcomes are independently ordered (no clustering).
|
||||
Observed runs = 26 (expected under H0 = 26.00, sd = 3.50)
|
||||
z = 0.000, p = 1.00e+00
|
||||
-> fail to reject H0 at alpha=0.05: failures are not serially clustered.
|
||||
|
||||
H1b -- pre-fix outcome vs. trial/write order directly (Wilcoxon)
|
||||
H0: trial index is drawn from the same distribution for PASS/FAIL
|
||||
(complements H1: the runs test only catches consecutive-value
|
||||
clustering, not a general rank-order trend).
|
||||
W = 332.0, p = 0.715
|
||||
-> fail to reject H0 at alpha=0.05: outcome is not associated with write order.
|
||||
|
||||
H2 -- pre-fix failure vs. disk location (Wilcoxon rank-sum test)
|
||||
H0: logical block number is drawn from the same distribution
|
||||
for PASS and FAIL trials (failure does not depend on location).
|
||||
W = 505.0, p = 0.000
|
||||
-> REJECT H0 at alpha=0.05: failure IS associated with LBN.
|
||||
|
||||
Secondary check -- sibling position (0/1/2) vs. outcome (chi-squared)
|
||||
chi-sq = 0.790, df = 2, p = 0.674
|
||||
-> fail to reject H0: outcome is not associated with sibling position.
|
||||
|
||||
H3 -- did the fix change the pass rate (two-proportion test)
|
||||
H0: pre-fix and post-fix trials share the same true pass rate.
|
||||
Pre-fix: 25/50 = 50.0% Post-fix (pooled, 3 arches): 150/150 = 100.0%
|
||||
chi-sq = 81.20, df = 1, p = 2.04e-19
|
||||
95% CI on the difference in pass rate: [-0.652, -0.348]
|
||||
-> REJECT H0 at alpha=0.05: the fix DID CHANGE the pass rate.
