Restore r2il-mask-abi-probe CI; compact EPIPHANIES into canonical architecture map - #1255

Conversation
The step was removed rather than left red because this job checks the OGAR sibling out with no `ref:`, so before `CallMask::words()` reached OGAR's DEFAULT branch it could only fail (16 x E0599, one class, all `words`). That precondition is now met: OGAR #305 merged, main a5b852e. Verified from the FILE, not the PR state -- a merge event is a claim about a pull request, while the gate depends on a symbol with particular semantics. `crates/ogar-r2il/src/lib.rs` at `?ref=main` has exactly one `impl CallMask` and `pub fn words(&self) -> &[u64]` at :492 returning `&self.words[..(self.len.div_ceil(64) as usize)]` -- sliced to the POPULATION, not the full MASK_WORDS carrier. That distinction is the whole point: a `words()` handing out the carrier would satisfy the merge event and fail `both_sides_span_the_same_words`, whose own disable is exactly "widened to the full carrier". Then reproduced CI's configuration rather than the local one: detached the OGAR sibling to `origin/main` (the method this entry used to measure the original 16 errors), ran the probe, restored the branch clean. CARGO_PROFILE_DEV_DEBUG=0 cargo test \ --manifest-path crates/r2il-mask-abi-probe/Cargo.toml -> 6/6 green, exit 0 Running it on the local feature branch would have proven nothing about CI, since that branch is not what the workflow checks out. Closes ISS-R2IL-PROBE-HAS-NO-CI-LINE-UNTIL-OGAR-305 (regraded RESOLVED in place, original OPEN text preserved as history) -- the risk it existed to keep visible was an excluded crate with no CI line, which is now gated. Gates: provenance + 5-arm self-test, entries index --check + --self-test, supersession regenerate-and-diff clean, append-only (9 files, ISSUES.md +94 lines), plan-dids, hook suite ALL PASSED, workflow YAML parses and the step is present in the `test` job.

Lands the tool alone. It has written NOTHING: no archive exists, and
EPIPHANIES.md is byte-identical (sha256 37f5c6f3…, 33,528 lines). Deliberately
NOT added to any workflow -- a --check gate would fail against a projection
that has not been authorised.
WHAT IT DOES: reads ONE input, inspects each entry's OWN structured
**Status:**/**Verdict:**/**State:** leading token, drops the explicitly
terminal set, deduplicates exact E-ids, emits a table. It consults no code, no
TECH_DEBT/STATUS_BOARD, no PR state, no plan, no supersession prose, no
citation decay, no model. Compaction, never adjudication.
The status parser is structured-field-only because a substring test drops
entries that merely CITE a terminal marker -- the measured shape here is a
sibling's caveat quoted as `(⊘ in E-FOO-1)`, the same error that over-counted
SUPERSEDED 9 -> 5 in the findings baseline. Unknown, absent and SHIPPED all
KEEP: an epistemic grade answers *how well established*, not *is it done*, and
a shipped implementation can still encode a durable insight.
MEASURED on the current EPIPHANIES.md (891 entries + 160 no-id + 6 structural):
10 terminal drops (⊘ 6, FIXED 2, SUPERSEDED 2), 6 duplicate E-ids, 875
survivors. Accounting balances with no remainder (asserted in-tool).
891 = 875 + 10 + 6.
The pass does NOT compact by row -- 891 -> 875 is 1.8%. The corpus almost
never marked anything terminal; it graded epistemically (FINDING 575, RULING
68, CORRECTION 26). Byte-wise it is 3.5 MB -> 222 KB (6.36%). Reported for a
decision rather than acted on.
Three defects found by measurement, all verified against the file and all
still OPEN pending a ruling -- which is why no projection is written:
* 160 dated entries carry NO id (plus one I- iron rule) and fall outside
the "dated E-id" shape entirely: neither kept, dropped nor duplicate, and
with no id there is nothing to find them by in the archive.
* the E-id regex can key an entry to a CITED id: line 27736's own
E-0xFFF-IS-ONE-ALIGNED-ADDRESS is unmatchable (lowercase x), so the row
would file under E-POLYGLOT-4096-IS-CONJECTURAL from later in the heading.
* it truncates at a lowercase suffix, collapsing E-X265-MORTON-SHIFT-1a and
-1b into `E-X265-MORTON-SHIFT-` and discarding one as a false duplicate.
Two bugs the self-test caught in my own work, both fixed: the test ids were
too short for the corpus E-id pattern, and the example status regex matched
NOTHING here -- the corpus writes `**Status:** RESOLVED`, bold closing after
the colon, so a space sits between `**` and the token. Without the added `\s*`
every entry read as no-status and nothing would have dropped.
Seven falsifiers, all passing: a cited ⊘/SUPERSEDED in prose keeps; an own
**Status:** SUPERSEDED drops; unknown and absent both keep; SHIPPED keeps;
dedup keeps newest and reports both occurrences; bare-date / id-less /
section headings are not entries; render is deterministic.

…rage check) Behaviour unchanged: self-test 7/7, 875 survivors, accounting balanced. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GXUahz73MZxtxWcfpHp9dG
- `--from` as the final argument raised IndexError; now prints usage, exit 2. - `--write`/`--check --from X` rendered the DEFAULT archive in the "Historical source" header; passes the selected archive. - read/write of the compact file pin encoding="utf-8". render() emits ⊘ and em dashes, so the locale encoding was not ours to inherit, and the prior errors="replace" on read would have reported a stale file rather than an encoding fault. The fourth finding is NOT fixed and is not the tool's to decide: COMPACT targets .claude/board/EPIPHANIES.md, which append_only_gate.py protects, so a compaction that shrinks it fails CI. Writing elsewhere contradicts the requested shape, so the target path is an open question for the operator. Behaviour unchanged: self-test 7/7, 875 survivors, accounting balanced.

…en archive
EPIPHANIES.md was 33,528 lines / 3.5 MB with no admission gate, so the
corpus had stopped being readable. It is now two artifacts:
EPIPHANIES-ARCHIVE-2026-09-20.md the record, byte-identical to the
pre-compaction file (3,487,543 bytes, sha256 37f5c6f3...), frozen
epiphanies-rows.json the consolidation data: one record per
archived heading with topic, priority, one-line finding, refs, and a
closed-out verdict
EPIPHANIES.md the generated projection: 988 lines,
959 live rows of 1051, 18x smaller
Nothing is deleted. Each row names its archive line, and the renderer
refuses a row whose line is not a real level-2 heading there.
The mechanical status filter was measured and rejected as the compaction
mechanism: this corpus grades epistemically (FINDING / RULING /
CORRECTION), so dropping explicit terminal tokens took 891 rows to 877 --
no compaction. It is kept as --measure, the archive census, which is what
it is honestly good for. Compaction comes from the consolidation instead.
Two parser defects found and fixed while measuring the archive: the E-id
regex could not match `E-0xFFF-...` (the lowercase x), so the heading's
CITED id was taken as its own; and `E-X265-MORTON-SHIFT-1a`/`-1b` both
truncated to the same key, discarding one as a false duplicate. Duplicate
count 6 -> 4 after.
EPIPHANIES.md leaves the append-only protected list: a projection
legitimately shrinks when a row is closed out. What replaces that gate is
stronger -- the board workflow now self-tests the compactor and fails if
the projection does not match its inputs, so a hand-edit or an
un-regenerated rows change is caught. Verified red-then-green.
Rule from here: new work goes to .claude/board/entries/; a rare surviving
Eureka is promoted into the projection citing its entry; the archive is
never appended to.

…ersession index Two red checks on 0db7fb2, both caused by the archiving step itself. citation-decay: archiving copied 3.5 MB of historical citations into a NEW file, so every citation the old EPIPHANIES.md carried reads as newly introduced to the two-revision arm. Five decayed -- statements that were already stale in the original and were preserved deliberately. It cannot be fixed the way the gate's own message says, because that remedy is an EDIT and the archive may never be edited. An archive is prose as it was written; its citations are historical statements, not live claims. Demanding they resolve against today's tree demands the record be rewritten, and a lossless copy would fail the gate for being a copy. So the frozen archive is excluded by name, with that reasoning in the source. The exclusion is narrow: the live projection generated FROM an archive makes current claims and is still held to them. The gate's self-test still proves both halves -- fires on a decay this PR introduces, silent on the backlog -- and the regression arm is green. supersession-index: the board is one of its inputs, so the EPIPHANIES change moved 27 rows. Regenerated, not hand-edited. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GXUahz73MZxtxWcfpHp9dG
… event log
The mechanical projection is replaced by a ONE-TIME semantic closeout plus
canonical compression. 1,040 historical entries -> 753 live -> 323 canonical
concepts; 33,528 lines -> 355. The archive is unchanged and still carries
every byte.
WHY THE MECHANICAL FILTER WAS RETIRED, MEASURED: 13 of 1,040 entries carry an
explicitly terminal status token. 702 are FINDING. This corpus grades
EPISTEMICALLY -- how well established a claim is -- never whether it is done,
so dropping terminal tokens took 891 rows to 877 and compacted nothing. That
parser is kept as --measure, the archive census, which prints the number and
the reason; it is no longer the compaction mechanism.
Per-topic folds ranged 1.1x (temporal/versioning 18->16) to 4.4x (DeepNSM
61->14), tracking whether the corpus actually iterated on a mechanism. A
single global ratio would have been the wrong instrument, and the two smallest
topics -- which finished first -- would have given exactly the wrong answer.
THREE PARSER DEFECTS, each losing or inventing identity:
- `E-0xFFF-...` was unmatchable (the lowercase x), so the heading's CITED id
was taken as its own.
- `E-X265-MORTON-SHIFT-1a`/`-1b` truncated to one key; one was discarded as
a false duplicate.
- a same-day counter, `2026-09-14 (3)`, stopped the separator scan, so 17
entries that own a real id were keyed by archive line.
Identity is now POSITIONAL: the leading token of the identifier position, or
the entry owns none. Two real headings pin both directions side by side --
`(3) — E-...` owns its id; `(2) — STORNO on \`E-...\`` only cites one and is
keyed by line. They look identical and mean opposite things.
The third defect was found by the merge's own verification, not by reading: a
worker returned an id where the parser had found none. The merge now separates
the two failure modes it can see -- a CITED id keeps the verdict and discards
the label (identity is the parser's, never the worker's), while a label
belonging to a different packet means the rows no longer line up and the batch
is refused.
IDENTITY IS NEVER MINTED. 874 E-*, 1 I-*, and 165 entries keyed by their
immutable archive line (`L12345`). Decisions are keyed by line, not id: three
ids legitimately recur, so an id-keyed map is ambiguous, and a line key cannot
drift from the archive the way a stored display string could. Every id in the
table is recomputed from the archive at render time.
A STRICT RE-JUDGEMENT over the two weakest-folding topics (109 rows) removed
14: board-meta notes, test fixtures, product positioning, and measurements
pinning no constant. It ran because three junk rows led to an inference that a
third of the table was residue; measured, planner genuinely holds 49 distinct
mechanisms. The three named rows were caught with the right class labels and
nothing else was. The 14 became CLOSED decisions rather than hidden rows, so
the accounting still balances and the archive-only count stays honest.
P is `—` on all 323 rows. Not an omission: no entry states a literal P0-P3,
and the rule is reuse-or-dash, never infer from importance.
The tool holds no semantic heuristics. It parses, accounts and renders; the
judgement is data in epiphanies-canon.json. Twenty-two falsifiers, each
proving a REFUSAL: a mutated archive, a decision naming no archive entry, an
undecided entry, a live entry absent from every row, one entry claimed by two
rows, a terminal state given a row, an off-vocabulary topic, an invented
priority, a decision keyed by an id instead of a line.

Both findings verified against the files first; both were real. 1. citation_decay.py -- the frozen-archive exclusion was written into collect_citations (the `--since` path) ONLY. main() globs DEFAULT_GLOBS itself and calls run(), which never filtered it, so CI went green on `--since` while a bare invocation still scanned the archive and failed on its deliberately preserved decays. Two code paths answering one question. Moved to is_frozen_archive() checked inside scan_file -- the single choke point every entry point passes through, so a caller cannot forget it. The now-redundant per-loop skip is gone: one place decides. New falsifier proves BOTH halves and the narrowness: the archive is skipped at the choke point, collect_citations agrees, and the SAME decayed citation in an ordinary board file is still reported. Measured after: the bare invocation reports 0 archive findings. Its exit 1 on the 135-decay pre-existing backlog is unchanged single-revision behaviour. 2. compact_epiphanies.py -- assert_archive_unchanged read `if want and want != got`, so an absent or empty recorded sha256 disabled the immutability check SILENTLY. A guard that cannot fire carries exactly as much information as one that never fires, and this guard exists for the one claim the whole design rests on. A missing hash is now refused. The recorded bytes and lines are validated against the file too, and render reports the MEASURED values rather than copying the decisions block -- the header is a claim about what was actually projected. The first version of that falsifier was VACUOUS and only the disable run showed it: with the hash-presence check removed, the refusal came from the byte/line check instead, because the fixture omitted those as well. The fixture now carries correct bytes and lines, so the missing hash is the only thing wrong with it. Both fixes disable-verified red-then-green, with every patch anchor asserted. All gates pass: both self-tests, --check, --since against the merge base, append_only_gate, entries_index --check, epiphany_provenance, plan_dids, and the anti-pattern hook suite.
