What

Orders a curated hit above the session transcripts that quote it, in every
interactive search route, and gives palace-diary hits a note saying they have no
citable source. #451 items F and G.

Why — measured

A paraphrased question ranks transcript copies above the curated card that answers
it, so a reader at the default limit never reaches the correction. On production
(wing 2g, limit 20) the CLAUDE.md chunk carrying the REFUTED banner came back at
rank 13 on bm25-fast and 14 on hybrid, while a transcript quoting the same
claim sat at rank 1. The reporting librarian named the class FAIL-D — right
file, right chunk, right markers, ranked below the cut
: the only failure that
passes every content check. Item G is its sibling — diary summaries rank first with
source_file rendering ? and nothing to verify them against.

How — and why this metric

New mempalace/result_ordering.py. The preference is bounded to near-duplicates:
a curated hit is promoted only over a hit that quotes substantially the same text, so
genuinely transcript-only recall keeps the ranker's order untouched.

Near-duplicate = overlap coefficient over word 3-grams ≥ 0.35, chosen by
measurement over 134 cross-kind hit pairs on production, not by taste:

metric true quoting pairs same-topic, non-quoting unrelated
bare token-set overlap 0.74 0.63 ← no discrimination —
3-gram Jaccard 0.16 peak ← threshold would be unsafe 0.10 —
3-gram overlap coeff. (chosen) 0.373 / 0.473 / 0.491 ≤ 0.323 0.000

A transcript quotes a card and surrounds it with conversation, so the two differ
wildly in length. Overlap asks "is most of the shorter one inside the longer one?"
— the actual question. Jaccard divides by the union and is punished by exactly the
surrounding conversation that makes a quote a quote. Shingles rather than bare tokens
because same-topic chunks share vocabulary but not word order. No embeddings — this
runs on every interactive search. 0.35 sits in the measured gap between 0.323 and 0.373.

prefer_curated() raises each hit to the earliest position it has earned: the
index of the topmost hit it directly duplicates, searching back no further than the
nearest earlier hit it does not outrank by kind (curated → transcript → diary).
A hit that earns nothing keeps the ranker's index. Passes repeat until the order
settles, so the value returned is a fixed point.

Both bounds came from review, not from design — and each needed a case my own
tests did not contain.

  1. Near-duplicate must not be transitive. Grouping by connected component made
    it so: with sim(A,B)=1.0, sim(B,C)=0.49, sim(A,C)=0.0, ['C','B','A']
    became ['A','C','B'] — A cleared C without sharing one 3-gram with it.
    Needs three hits to show; every test I had used two.
  2. The rank test must guard every hit PASSED, not just the hit earned from.
    With ['DIARY','CARD','TRANSCRIPT'] and the transcript duplicating both, the
    transcript earned index 0 from the diary it outranks and overtook the card on the
    way — a curated card demoted below a transcript quoting it, the exact inverse
    of this feature. Needs one hit duplicating two others of different kinds; nothing
    covered that.

Both are now tests, alongside property tests over 4,000 randomised three-kind
inputs each
for idempotence and for the bound as a pairwise invariant. A single
pass is not idempotent — a reorder manufactures new adjacencies — so passes iterate;
termination is not hoped for but argued: a hit only moves up past hits it strictly
outranks, which strictly increases sum(rank × position), and that sum is bounded.
Measured: 5 passes worst case against a cap of 8, and 834 of 4,000 needed two or
more
— which is the bug, quantified.

Collateral overtaking of non-duplicates lying between a hit and the copy it earned
is unavoidable for a single-list ordering and is stated in the docstring rather than
hidden: the alternative is to leave the curated hit buried.

Wired into the CLI's bm25-fast, hybrid and MCP-envelope routes, and into
searcher.search_memories (main envelope + the vector-disabled BM25 short-circuit)
so MCP mempalace_search gets it from the daemon host.

Acceptance — drift-free, on production, read-only

⚠️ A two-process before/after is not trustworthy on this corpus tonight. The
re-mine moved curated ranks repeatedly while I measured, and an early two-arm run
showed [] → [1] that I nearly reported as the widen firing — direct instrumentation
showed one daemon call and a narrow fetch that already had the card at rank 1. It was
the corpus, not the code.
So the table is a within-process A/B: one fetch, ranks
recorded, then the reorder applied to a copy of that same response.

query route limit before after
verbatim probe hybrid 20 [1, 7] [1, 4]
row 1 paraphrase fast 10 / 20 [2] / [2, 14] unchanged
row 1 paraphrase hybrid 10 / 20 [7, 10] / [2, 16, 17, 20] unchanged
verbatim probe fast + hybrid 10 / 20 3 cells unchanged
literal iproute fast + hybrid 10 / 20 4 cells unchanged
row 8 negative control fast + hybrid 10 / 20 4 cells unchanged

The correct bound REDUCES the measured effect, and that is the honest headline

1 of 16 cells moves where the buggy version moved 8. I diagnosed that rather than
assuming it. On the paraphrase row at limit 20:

kinds:  1 transcript · 2 FILE · 3-11 transcript · 12 diary · 13 transcript · 14 FILE · …
curated hit at rank 14:
   near-dups above it        = rank 1 (sim 0.373)   <- its only one
   barrier (nearest earlier hit it does not outrank) = rank 2, the OTHER curated hit
   reachable given the barrier = none

The old jump from 14 to 1 was only possible by overtaking a fellow curated hit —
equal rank, neither outranks the other. That overtake was the defect, not the feature.
And note what the barrier implies: it only blocks when a curated document is already
above, here at rank 2, comfortably above the cut — so the promotion it prevents is
precisely the one the reader did not need. The feature still fires when a curated hit
is genuinely buried under transcripts alone, which is the #451 case.

Rows 2–7 are void — the lead confirmed those files were never in this
wing
.

Conditional widen — closing the fetched-window bound

Reordering can only promote a hit the ranker actually returned. On the measured
case the card sat at rank 13 of 20 while the reader asked for 10, so the ordering fix
alone left the default limit unchanged.

_widen_when_nothing_curated makes exactly one wider fetch (2× the limit, capped
at 40) when no_curated_source(hits) is true, then reorders and truncates back to the
requested limit. When a curated hit is already present — the common case — no extra
call is made at all
. This wave is cutting daemon load, so the round trip is spent
only where the search is actually broken. A failed, unusable or not-actually-wider
second call degrades to the original hits, and the header still fires when the widened
window also found nothing curated.

⚠️ Acceptance honesty: the trigger condition was real and measured on wing 2g
earlier tonight (curated ranks [] at limit 10, [13] at limit 20). A re-mine has
since surfaced those cards above the cut, so across 11 probe queries the condition
no longer reproduces and I could not demonstrate the widen firing against
production. Both branches are covered by unit tests asserting the daemon call
count
(1 in the common case, 2 in the broken case); the live path is not
production-demonstrated and I am not claiming it is.**

Known inconsistency when the widen does fire: results come from the wider
fetch while warnings / total_before_filter / available_in_scope still describe
the narrow call. Left as-is deliberately — carrying the wider response's diagnostics
instead is a one-line change, say the word if you want it.

Tests

44 new, TDD (each watched fail first):

  • tests/test_result_ordering.py — 32: similarity (identity, disjoint, containment
    despite length, symmetry, empty); near-duplicate thresholds and the short-text
    refusal; a test pinning the calibrated threshold inside the measured gap; and
    prefer_curated — promotion, the bound (no near-duplicate ⇒ no move),
    transcript-only untouched, two curated hits not reordering each other, diary below
    curated, diary untouched without a curated near-duplicate, relative order of
    unrelated hits, promotion target, idempotence, kind derivation, non-dict/non-list
    tolerance, and the O(n²) size guard.
  • tests/test_cli_daemon.py — 10: fast route promotes, fast route leaves
    transcript-only recall alone
    , MCP-envelope route applies it, diary compact tag,
    and six for the widen — no widen when curated is present (exactly one daemon
    call
    ), widen fires once at 2× (two calls), widened card clears the cut and the
    result is truncated, a widened-but-still-uncurated window keeps the header firing,
    a failed second call degrades safely, and no widen when the limit already exceeds
    the cap.
  • tests/test_provenance.py — 2: diary note, and that it survives annotation.

Full suite 7152 collected, 7065 passed, 82 skipped. The 5 test_init.py
leaked_pythonpath failures are the known worktree baseline (#454), not from this
change. ruff check + ruff format --check clean; scripts/check-docs.sh clean 7/7.

A paraphrased question ranks session transcripts above the curated card
that answers it, so a reader at the default limit never reaches the
correction. Measured on production (wing 2g, limit 20): the CLAUDE.md
chunk carrying the REFUTED banner came back at rank 13 on bm25-fast and
14 on hybrid while a transcript quoting the same claim sat at rank 1.
The reporting librarian named the class FAIL-D — right file, right
chunk, right markers, ranked below the cut. Item G is its sibling:
palace diary summaries rank first with no citable source at all.

New `mempalace/result_ordering.py`. A curated hit is promoted only over
a hit it is a NEAR-DUPLICATE of, so this cannot swamp genuinely
transcript-only recall:

  similarity()        overlap coefficient over word 3-grams
  is_near_duplicate() threshold 0.35, refuses to decide on short text
  prefer_curated()    groups near-duplicates, orders curated -> transcript
                      -> diary within a group, emits the group at its
                      earliest member's position; everything else keeps
                      the ranker's order exactly

Why overlap-over-shingles and not Jaccard, measured over 134 cross-kind
pairs on production: bare token overlap is 0.63 even for merely
same-topic chunks (no discrimination); 3-gram Jaccard peaks at 0.16 for
TRUE quoting pairs (any workable threshold would be dangerously low);
3-gram overlap coefficient gives 0.373/0.473/0.491 for the three genuine
buried-card pairs against <=0.323 for same-topic non-quoting pairs and
0.000 for unrelated files. 0.35 sits in that gap. A transcript quotes a
card and surrounds it with conversation, so the two differ wildly in
length — overlap asks "is most of the shorter inside the longer", which
is the actual question; Jaccard is punished by exactly the surrounding
conversation that makes a quote a quote.

Wired into every interactive route: the CLI's bm25-fast, hybrid and
MCP-envelope paths, and `searcher.search_memories` (both its main
envelope and the vector-disabled BM25 short-circuit) so MCP
`mempalace_search` gets it from the daemon host.

Item G: diary hits render "palace diary summary — no source file" and
sort below curated hits within a near-duplicate group.

Reordering can only promote a hit the ranker actually returned. On the
measured #451 case the curated card sat at rank 13 of 20 while the
reader asked for 10 — it was never in the window to promote, so the
ordering fix alone left the default limit unchanged.

`_widen_when_nothing_curated` makes exactly one wider fetch (2x the
limit, capped at 40) when `no_curated_source(hits)` is true, then the
result is reordered and truncated back to the requested limit. When a
curated hit is already present — the common case — no extra call is
made at all. This wave is cutting daemon load, so the extra round trip
is spent only in the case that is actually broken.

Degrades safely: a failed, unusable or not-actually-wider second call
falls back to the original hits. The header still fires when the
widened window also found nothing curated, so a wider search that still
has no curated document says so rather than going quiet.

Applied to the bm25-fast and hybrid CLI routes. `_daemon_search_fast`'s
fetch-and-normalise half is extracted as `_fast_hits` so the widen can
reuse it.

Note on acceptance: the trigger condition (nothing curated inside the
limit, a curated card deeper) was measured on wing 2g earlier tonight —
curated ranks [] at limit 10 and [13] at limit 20 — but a re-mine has
since surfaced those cards above the cut, so the condition no longer
reproduces there and the live path could not be demonstrated on
production. Both branches are covered by unit tests, including the
daemon call counts.

Part of #451

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The docstring promised a curated hit is promoted only over hits it is a
near-duplicate of. Grouping by connected component did not deliver that:
union-find makes the relation transitive, so a chain A~B~C put A, B and
C in one group and let A jump over C with no shared 3-gram at all.

Reviewer's measured triple, now a test:

    sim(A, B) = 1.0    A is wholly contained in B
    sim(B, C) = 0.49   B and C share their second half
    sim(A, C) = 0.0    A and C share nothing
    ['C', 'B', 'A'] -> ['A', 'C', 'B']

A cleared C without duplicating it, and B — a true near-duplicate of A —
was pushed below C. Both are the bound leaking.

The grouping is replaced by a direct-only rule. Each hit earns the index
of the topmost hit it DIRECTLY duplicates and outranks by kind, and the
list sorts by (earned index, kind, original index). A hit that earns
nothing keeps the ranker's index, so a promoted hit moves no further
than the copy it cleared and everything else holds its relative order.
Same triple now gives ['C', 'A', 'B']: A clears B, does not touch C, and
B keeps its place behind C.

Verified drift-free on production — one fetch, ranks before and after
the reorder applied to a copy, so the re-mine running tonight cannot be
mistaken for the code. Curated ranks [2,14] -> [1,3] and [14,17,20] ->
[3,17,20] on the paraphrase row; the negative control and every
already-high curated hit unchanged.

Part of #451

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two defects in the literal-bound rewrite, both executed by review.

1. The rank test guarded the hit being EARNED FROM, never the hits
   being PASSED. Repro: ['DIARY','CARD','TRANSCRIPT'] where the
   transcript duplicates both the diary (0.444) and the card (0.444).
   The transcript earned index 0 from the diary it outranks and, in
   landing there, sailed past the card it duplicates and does NOT
   outrank -> ['TRANSCRIPT','DIARY','CARD']. A curated card demoted
   below a transcript quoting it: the exact inverse of the feature.
   The backward scan now stops at the nearest earlier hit this one does
   not outrank, so nothing can pass what it does not outrank.

2. A single pass is not idempotent: a reorder creates new adjacencies
   and manufactures fresh earns. Passes now repeat until the order
   settles, so the value returned is a fixed point. Termination is not
   hoped for -- a hit only moves up past hits it strictly outranks,
   which strictly increases sum(rank * position), and that sum is
   bounded. Measured over 4000 randomised inputs: 5 passes worst case
   against a cap of 8, and 834 of 4000 needed two or more, which is the
   bug.

Tests: the diary/card/transcript repro; the A/B/C triple still
['C','A','B']; and two property tests over 4000 randomised three-kind
inputs each -- idempotence, and the bound as a pairwise invariant (no
hit ends up above one it did not outrank). Nothing covered one hit
duplicating two others of DIFFERENT kinds, which is why the suite
missed it.

Docstring no longer claims "only above a direct near-duplicate". It
states the real rule -- earliest earned position, bounded by the rank
barrier -- and that collateral overtaking of non-duplicates in between
is unavoidable for a single-list ordering.

Measured consequence, stated plainly: the correct bound REDUCES the
effect on the current corpus, 1 of 16 probe cells moving where the
buggy version moved 8. Diagnosed rather than assumed -- on the
paraphrase row the rank-14 card's only near-duplicate above it is the
transcript at rank 1, and its barrier is the OTHER curated hit at rank
2. The old jump to rank 1 was only possible by overtaking that fellow
curated hit. A curated document is already at rank 2, above the cut, so
the blocked promotion is the case where promotion matters least.

At 8 passes the ordering loop was reaching its cap routinely on dense
inputs and then returning a NON-fixed-point silently, which contradicts
the fixed-point promise in the docstring.

Measured here on a dense stress generator at n=40 — the widest window
the widen can fetch, and far denser than a real search window — over
600 inputs each:

    cap   8 -> 591/600 non-fixed-points
    cap  32 ->   2/600
    cap  48 ->   0/600
    cap 128 ->   0/600

Set to 48 rather than the reviewed 32: 32 still left 2/600 here, and a
higher cap is free — every row above ran in the same 1.22s, because the
loop exits on the first pass that moves nothing. The test pins >= 48 so
a future trim has to re-measure.

Exhausting the cap now logs a warning naming the pass count and hit
count. An under-settled order is otherwise indistinguishable from a
settled one, which is the property that made the old cap's failure
invisible.

One entry file under the new per-file layout (#473), seq from
`fork_changes.py --next-seq`, `commit: HEAD` for the merge step to
resolve, and `fork_pr: 477` to resolve it from. No count literals —
#473 removed them, so the old README/CLAUDE.md edits are deliberately
not replayed.

All three renderers re-run; check-docs clean 7/7, including the new 2b
ancestry check.

…ering it as a link (#476)

lucid's finding: seven entries merged since #480 still read
`commit: HEAD`, and step 2b could not see any of them. Verified, and the
mechanism is worth stating precisely because the obvious fix would not
have worked:

  fork_changes.iter_commit_refs SKIPS HEAD, so those entries never reach
  the ancestry predicate at all. Hardening the predicate alone changes
  NOTHING. (`git merge-base --is-ancestor HEAD HEAD` also exits 0, so
  both halves had to learn about the literal.)

⇒ 2b caught a WRONG sha and was blind to a MISSING one.

`--strict-resolved` / `STRICT_RESOLVED=1` enumerates HEAD entries
(`fork_changes.py --commit-refs --include-head`) and fails on them,
naming the entry and telling you to run the sweep. Wired in CI to
`push` + `refs/heads/main` only: a pull request legitimately carries
HEAD, because the squash commit it will point at does not exist yet.
Loud, never auto-fixing — resolving is the sweep's job.

POSITIVE CONTROL, both directions, on the same tree (1 HEAD entry):
  permissive  -> exit 0
  --strict-resolved -> exit 1, "entry 'init-test-cwd-relative-syspath'
                       still has `commit: HEAD` on main"
  STRICT_RESOLVED=1 -> exit 1

`https://github.com/techempower-org/mempalace/commit/HEAD` is a VALID
GitHub URL that resolves to whatever is at main's tip. So the 8 links in
FORK_CHANGELOG.md and 7 in the README table pointed at an unrelated
commit while looking exactly like real references — a reader cannot tell
them apart, which makes it worse than an obviously missing value.
`commit_link()` now renders "`HEAD` — pending resolution" as plain text.
After this: 0 such links in either file.

Worth noting an old entry's body already described "broken
``[HEAD](commit/HEAD)`` links", so this had been seen before and came
back. A rendering rule is a better place for it than a habit.

More HEAD entries land after this (#477, #490, stage A, #485), so a
resolution commit would be stale before it merged. The sweep is one
dedicated PR at the very end of the cascade, and it is the first PR the
strict check has to pass. docs/fork-changes/README.md now says the sweep
is the lead's last step of every wave, and why per-lane resolution
cannot work.

Caught while wiring CI: my first edit added a SECOND `env:` key to the
check-docs step, which YAML resolves by keeping the last one — silently
dropping `GH_TOKEN`, which step 4 needs for upstream PR state. Merged
into the existing block and asserted both keys survive by parsing the
workflow.

… for unresolved placeholders (#476) (#492)

* fix(scripts): resolve `commit: HEAD` from the commit that added the entry file (#476)

`fork_pr` could not carry this on its own: a lane cannot know its own PR
number while writing the entry, which is the same chicken-and-egg as the
sha. #480's own entry is the proof — I wrote `fork_pr: 0` as a
placeholder, deleted it rather than ship a wrong number, and left an
entry nothing could resolve.

The commit that ADDED an entry's file is the squash commit by
construction, since the file arrives with the pull request:

    git log --follow --diff-filter=A --format=%H -- docs/fork-changes/<file>

Deterministic, offline, needs nothing from the author, and immune to a
squash subject reworded at merge time — which defeated 4 of the 27 cases
in the #472 sweep. `--follow` so a renamed entry file still resolves to
its original add, and the LAST add is taken, since a rename history can
list several.

`fork_pr` becomes a cross-check rather than the key: when present, the
API answer is compared and a DISAGREEMENT refuses to resolve, because
two independent mechanisms disagreeing is the worst case in which to
pick one. It also still works as the fallback when file-add cannot
answer.

This runs ONLY on an entry whose `commit` is literally `HEAD`.

Every one of the 137 entry files that predates the one-file-per-entry
split was created by the SPLIT's own commit. So asking "what added this
file" about an already-resolved entry returns the migration commit.
MEASURED on this branch, before the guard existed:

  entry `scripts-maintain-fork-changes`  field says 9060e09  (correct)
  git log --diff-filter=A on its file →  6da8775            (the split)

That would have rewritten 137 correct historical shas to one wrong
value — and 6da8775 IS an ancestor of main, so it would have passed the
new ancestry check forever and read as correct. Exactly the
wrong-but-plausible failure the reviewer named on #480. A test pins the
boundary in both directions, and asserts the resolver never even asks
about an entry that already has a sha.

Ran against main: resolved exactly ONE entry — #480's own,
`commit: HEAD → 6da8775` — and left the other 137 untouched, which is
the boundary holding in practice rather than only in the unit test.
6da8775 verified an ancestor of main.

The 2026-05-28 `scripts-maintain-fork-changes` entry needed no work: its
`commit` is already 9060e09 and already an ancestor. It looked like an
unresolved HEAD entry only because the entry is ABOUT HEAD resolution,
so the literal string `commit:HEAD` appears twice in its own prose — a
field-shaped grep matches the changelog entry that documents the field.

docs/fork-changes/README.md updated: `fork_pr` is documentation and a
cross-check, not load-bearing, and the boundary hazard is written down
so nobody widens it.

* docs+fix: fill fork_pr after `gh pr create`; surface an unverifiable one (#476)

GitHub's next PR number is not predictable: a lane wrote `fork_pr: 483`
before opening and the PR came back 490. A guessed number is the #472
failure in a new coat — a confidently wrong field instead of a visibly
unresolved one — so the directory README now says to fill `fork_pr` in
AFTER `gh pr create` returns it, and that leaving it absent is the safe
default since file-add is primary.

Worth stating what a wrong number can and cannot do, because it decides
how much this matters. It cannot corrupt the sha:

  - points at another MERGED PR  -> its different answer trips the
                                    existing cross-check refusal
  - unverifiable (404/unmerged)  -> file-add stands alone and is
                                    already right

MEASURED: PR 483 does not exist (404), so lucid's guess falls in the
second bucket and resolves correctly anyway.

But "resolves correctly anyway" is how a wrong field survives, so the
second case is now printed as an ADVISORY — "resolved from file-add;
fork_pr #483 is unverifiable — check it" — rather than silently ignored.
Deliberately not folded into the blocking list: an advisory that fails
`--check` is an advisory the next person deletes.

The function returns `(changes, unresolved, notes)` so the advisory is
actually reported. I had first appended to a `notes` list that nothing
returned — dead code that LOOKED like it reported something, which is
the same class of defect as a check that enumerates nothing.

* test(scripts): file-add resolution against real git, incl. the no-fork_pr case (#476)

The existing tests stub `adding_commit`, so they prove the wiring but
not the git invocation. These drive real `git log` in a temp repo.

The case that matters is #480's own entry: `commit: HEAD` and NO
`fork_pr`, because the entry was written before the PR existed and a
guessed number would have been worse than none. It is the reason
file-add is the primary mechanism rather than a fallback. VERIFIED live
on this repo as well — the entry's file was added by 6da8775, which is
#480's squash commit.

Measured on main (7df8dee): 8 entries carry `commit: HEAD`, and exactly
ONE of them lacks `fork_pr` — that one.

Four tests:
- no `fork_pr` resolves to the ADDING commit, not the tip, with two
  unrelated commits on either side of it, and emits no advisory (there
  is no number to cross-check or warn about)
- a LATER EDIT of the entry does not move the answer (`--diff-filter=A`
  means the add, so a typo fix or reworded body must not re-point a
  resolved sha)
- a RENAMED entry file still resolves to its original add. Entry
  filenames embed the date, so correcting a date renames the file;
  `--follow` is what keeps that from silently re-pointing the sha at the
  rename commit
- an untracked path returns None and is reported, never guessed

* docs(fork-changes): entry for the sha-resolution hardening (#476)

`commit: HEAD` and no `fork_pr` yet — deliberately. The PR number does
not exist until `gh pr create` returns it, and a guessed number is a

in immediately after the PR is opened, in the following commit.

* fix(scripts): never resolve an entry against a feature branch (#476)

Filling in `fork_pr: 492` — the number `gh pr create` actually returned,
not a guess — surfaced a way file-add could recreate #472 through a new
door, so this closes it before the mechanism ships.

Asked about a FEATURE BRANCH, "what added this file" truthfully answers
*the branch commit*. Written into the entry, the squash would orphan it
moments later — which is precisely the failure this mechanism replaced.
MEASURED on this branch: `git_file_add_commit(<my entry>)` with the
default branch returns f87f9c1, the branch commit.

The default `--branch=origin/main` already prevents it, and that is the
property rather than an accident: against `origin/main` an unmerged
entry finds NO add, so it stays `HEAD` instead of acquiring a sha that
is about to become unreachable. Verified end to end — running the sweep
command on this branch resolved the 8 landed entries from main's history
and left THIS PR's own entry untouched at `HEAD`, which is exactly the
behaviour the sweep needs.

A test now pins both halves in one place: asked about the branch it
returns the branch commit, asked about main it returns None, and
`resolve_head_by_file_add` reports rather than resolves. The README says
resolve against `origin/main`, never a branch, and why.

(The 8 entries that run resolved in my working tree were reverted — the
sweep is its own PR, per the lead.)

* fix(scripts): refuse to write a sha that is not an ancestor of origin/main (#476)

Oracle's rider, and it is a better fix than what I had. Before any
resolved sha is written, `git_is_ancestor(sha, origin/main)` must hold;
otherwise the entry is reported and `--check` exits non-zero.

The `--branch=origin/main` default already made a branch commit hard to
write. But a default is one argument away from being wrong, and the
question the caller actually needs answered is not "which ref did you
ask about" — it is "is this commit on main". Asserting that directly
makes the hazard IMPOSSIBLE rather than unlikely, and it holds whatever
`--branch` is passed.

Correcting my own framing while I am here, because the lead caught it
and the record should be right: the previous commit
("never resolve an entry against a feature branch") changed NO code —
`maintain-fork-changes.py` is byte-identical across it. It added a test
and documentation for a property the `origin/main` default already had.
Calling that "closing the hazard" was an over-claim: I documented a
safeguard and described it as building one. THIS commit is the code fix.

3 tests: a branch-only sha is refused and never written; the verify ref
stays `origin/main` even when `--branch` is a feature branch; an
ancestor sha still resolves. The real-git fixtures pass `verify_ref`
explicitly, since a temp repo has no `origin/main` — the real
`git_is_ancestor` still runs, against that repo's own ref.

Verified live: with the gate in place the sweep still resolves all 8
landed entries against origin/main (reverted here — the sweep is its own
PR). Full suite 7307 passed.

* fix(scripts): bind via_api unconditionally so term order cannot break it (#476)

Oracle's note: the unverifiable-`fork_pr` advisory reads `via_api`, which
was assigned only inside `if pr and fetch is not None:` — so it was safe
purely by SHORT-CIRCUIT ORDER in the later condition. Reordering those
terms, a harmless-looking edit, would have turned it into a NameError on
every entry that carries no `fork_pr`, which is exactly the entry the
file-add mechanism exists for.

Asked for a comment; binding it unconditionally instead, because that is
Oracle's own principle applied one level down — the ancestry gate was
preferred over a default plus a README for the same reason. Make the
edit safe rather than forbid it. The comment stays too, saying why.

PROVEN rather than argued: a copy of the module with the terms reordered
(`if not via_api and pr and fetch is not None:`) resolves an entry with
NO `fork_pr` and raises nothing. Before this, that reorder was a latent
crash.

* docs(specs): design spec for a failure-shape index keyed on the action

Records the class the 2g-c6 session named: an instrument returning a TRUE
answer to a NARROWER question than the one asked, with a PASSING positive
control. Seeds it with 25 measured instances (21 individually citable) from
Oracle PART 25, this wave's mempalace cards, and 2g-c6's night.

The class defeats the corpus's standing remedy. "Get a positive control
before trusting a zero" assumes a control that can fail; here it passes,
because it proves the reader works rather than that the reader was aimed at
the question asked.

Applies 2g's LAWS-INDEX arrival-phrasing model (n=11: 10 of 11 arrival
phrasings return zero against cards that exist) and names #497's
pre-mutation hook as the caller that already produces the query key.

The minimal slice measures before it builds: a labelled corpus plus a recall
harness that interleaves baseline and candidate per query, since #477
measured a card moving rank 13 to 1 on an unmodified tree within 30 minutes.
Four falsifiers are written down, including the one most likely to produce a
false success -- triggers authored by the lane that wrote the cards.

…rved slot)

In a wing with ~941K transcript drawers `mempalace search --limit 3`
returned three session transcripts and the reader concluded the corpus
held nothing curated. The first curated document ranks 14-27 (#526).

TWO causes, both measured on production before this was written.

1. The requested limit sizes the hybrid FUSION CANDIDATE POOL, not just
   the cut. limit=3 and limit=30 return different top-3 drawers for the
   same query, while the bm25 route is stable across limits; repeated
   identical calls are deterministic, so this is not drift. At --limit 3
   the curated document is not ranked below the cut — it is never a
   candidate. #477's widen already fired here but computed
   min(n*2, 40) = SIX at limit 3, and the curated layer begins at 14: it
   fired and landed short.

2. #477's ordering cannot lift it. That ordering is bounded to
   near-duplicates by design, and review hardened the bound twice.
   Measured similarity between the first curated hit and the top-3
   transcripts above it: 0.0/0.0/0.0 on one query, 0.008 on another,
   against a 0.35 threshold. #477 fixes "a transcript that QUOTES the
   card outranks the card"; this is "the same topic with no shared
   3-grams". Different defect, and re-ranking is the wrong instrument.

So: a conditional deeper fetch to max(limit, 30) — a floor, not a
multiple — fired only when the shallow result has no curated hit; then
one reserved slot, the LAST of the N, for the top curated hit in the
ranker's own order.

The promotion is MARKED on both channels: `promoted: true` and
`promoted_from_rank` on the hit in --json, `⟨curated, promoted from
rank K⟩` in prose, plus top-level `curated_first_rank` = the rank in the
deep fetch BEFORE reordering. Taken after reordering it would be 1
almost every time and say nothing about corpus depth. A silent promotion
would be #526's own error in reverse: the reader could not tell "ranked
here" from "reserved here".

Conditional because the depth is not free: a limit-30 hybrid call on
wing 2g measured 19-22 s (#533). Measured after: base 14.49/14.46 s vs
head 14.33/15.92 s on the hybrid-fallback query, and 0.18-0.26 vs
0.16-0.24 s on the bm25 route (n=2 per arm, interleaved) — no
measurable regression, because the cost is the hybrid call itself rather
than the row count.

`_WIDEN_FACTOR`/`_WIDEN_CAP` are gone; the three #477 tests that asserted
that arithmetic are updated to the new contract rather than deleted.
Curated means source_kind file OR memory, matching no_curated_source and
prefer_curated — using "file" alone would let a memory-only result
trigger the deep fetch while reporting curated_first_rank: null.

… fetch + reserved slot (#526) (#534)

## What

`mempalace search --limit 3` can now return a curated document in a wing where the
curated layer begins at rank 14–27. Two mechanisms, a conditional deeper fetch and one
**reserved, marked** slot. #526 fix 2.

## Why — two causes, both measured on production before this was written

**1. The requested limit sizes the hybrid fusion candidate pool, not just the cut.**

| control | result |
|---|---|
| same query + limit, twice | **identical** — not drift, not nondeterminism |
| hybrid: limit-3 top-3 vs limit-30 top-3 | **different drawers** |
| bm25-fast: limit-3 top-3 vs limit-30 top-3 | **same drawers** (pool-stable) |
| Q5 curated hit | **rank 1** of the limit-30 fetch, **absent** from the limit-3 fetch |

So at `--limit 3` the curated document is not ranked below the cut — **it is never a
candidate.** #477's widen already fired here, but computed `min(n*2, 40)` = **6** at
limit 3 while the curated layer begins at 14: it fired and landed short.

**2. #477's ordering cannot lift it, and that is by design.**

```
Q2  deep-fetch curated ranks pre-reorder = [14, 15, 24, 25, 30]
    after prefer_curated                 = [14, 15, 24, 25, 30]   ← nothing moved
    sim(first curated, top-3 transcripts) = 0.0, 0.0, 0.0
Q1  pre=[15] post=[15]  sim = 0.008        (threshold 0.35)
```

#477 fixes *a transcript that **quotes** the card outranks the card* — near-duplicate
ordering is exactly right for that. #526 is *the same **topic** with no shared 3-grams*.
Two review rounds hardened #477's bound deliberately; it is not under-tuned, it is the
wrong instrument. Relaxing it would mean dropping the threshold to ~0, i.e. "curated
always first". Hence a reserved slot rather than a re-rank.

## How

* **Conditional deep fetch** to `max(limit, 30)` — a floor, not a multiple — fired only
  when the shallow result contains no curated hit. `_WIDEN_FACTOR`/`_WIDEN_CAP` are gone.
* **One reserved slot**, the last of the N, for the top curated hit *in the ranker's own
  order*, only when the top N would otherwise contain none.
* **Marked on both channels**, because a silent promotion would be #526's own error in
  reverse — the reader could not tell "ranked here" from "reserved here":
  * `--json`: `promoted: true` and `promoted_from_rank` on the hit, plus top-level
    `curated_first_rank`
  * prose: `⟨curated, promoted from rank K⟩`
* `curated_first_rank` is the rank in the deep fetch **before** reordering. Taken after,
  it would be 1 almost every time a curated hit exists and would say nothing about
  corpus depth — which is the one thing the banner in PR 2 needs it to say.

**Producer/consumer:** the daemon's `/search/fast` and `/search/hybrid` payload (the deep
fetch) produces; the CLI's truncation consumes, after `#477`'s `prefer_curated`. Both are
driven together in `tests/test_search_depth.py`. `curated_first_rank` is itself the
producer for PR 2's banner, and the joint test that pins their agreement is already
written and lands there.

## Acceptance — production, wing 2g, `--limit 3`, read-only

Five queries pre-registered before any code. Q1–Q4 are the published defect queries; Q5
is a **positive control (lead-approved substitution — 2g-c6's query string was never
recorded anywhere)**, present so a table that reads all-zero cannot be mistaken for a
working instrument.

| # | query | route | `curated_first_rank` | curated in top 3 |
|---|---|---|---|---|
| Q1 | acs_tr069 cert context DO NOT swap this file | hybrid fallback | 15 | ✅ slot 3, marked |
| Q2 | cmhs inbound parameter handler binary | bm25-fast | `null` | — |
| Q3 | femtocell trap config bank | hybrid fallback | 27 | ✅ slot 3, marked |
| Q4 | globalCellId derived at cell setup | bm25-fast | 15 | ✅ slot 3, marked |
| Q5 | ip route get 192.168.157.186 *(control)* | bm25-fast | 9 | ✅ slot 3, marked |

**Four of five now return a curated hit where the base returned zero.** Q2 is reported
honestly: on the bm25 route it takes, no curated document lies within depth 30, so it
returns `null` rather than inventing a rank. Its curated hits *are* reachable on the
hybrid route (ranks 14/15/24/25/30) — a route-selection limit, not a depth one, filed separately as #537 rather than widening this PR.

### Latency, both arms, interleaved, n=2 per arm

| route | base | head |
|---|---|---|
| hybrid fallback | 14.49 / 14.46 s | 14.33 / 15.92 s |
| bm25-fast | 0.19–0.26 s | 0.16–0.24 s |

No measurable regression: the cost is the hybrid **call**, not the row count — which is
also why the trigger stays conditional rather than deepening every search (#533).

## Tests

15 new in `tests/test_search_depth.py`: the depth floor (driven through the helper,
because a route-level test cannot see it once the shallow fetch already returned
`limit` rows), the conditional trigger and its no-op cases, `curated_first_rank`
pre-reorder and `null`, reservation of the last slot, both marking channels,
`--limit 1`, and "no promotion claimed when it ranked there".

Three #477 tests asserted the `min(n*2, 40)` arithmetic this PR removes; they are
**updated to the new contract, not deleted**, and say why in their docstrings.

Full suite **7517 passed, 0 failed**. `ruff check` and `ruff format --check` clean.
`scripts/check-docs.sh` clean 7/7.

> change adds no imports.

"no curated document matched" is a claim about the STORE. What was
measured is the RETURNED SET, and in a wing with ~941K transcript
drawers the curated layer begins at rank 14-27, so at --limit 3 the
sentence was true of the result and false of the corpus — read by two
sessions as "this project has nothing curated on that" (#526).

Three cases now, on one result object:

  curated ranked inside the limit   -> nothing said about curation
  curated promoted from rank K      -> "1 curated hit promoted from rank K;
                                        the curated layer in this wing begins
                                        there - widen the pool with --limit 30"
  none within the deep fetch        -> "no curated document in the top N",
                                        and NO rank clause, because no K exists

The advice names the mechanism. The requested limit sizes the hybrid
fusion candidate pool (#534), so --limit 30 is not "scroll further down
the list", it is "widen the pool" — the document was never a candidate.

JOINT PRODUCER/CONSUMER TEST, written before the producer shipped so the
field's shape was fixed by the consumer's need: tests/
test_search_banner_contract.py drives one result object from
curated_first_rank (#534) to the rendered banner across all three cases
and asserts the printed K equals the K in --json, parametrised at 14 and
27. A banner whose number disagrees with the field is worse than no
number: one reader acts on the prose, another parses the field.

The old all-transcript / transcript-plus-diary split is dropped from the
banner; the per-hit ⟨transcript⟩ / ⟨diary⟩ tags carry it, and at header
level the useful statement is the depth. all_transcript() consequently
has no production caller — kept as a tested predicate, with its "for the
header line" docstring corrected so it does not describe behaviour that
no longer exists.

Three #477 banner tests asserted the old wording; updated to the new
contract, not deleted, and one now also asserts the phrase "no curated
document matched" is ABSENT.

## fix(search): the banner states the DEPTH, not the store (#526, PR 2 of 4)

Stacked on #534 (curated_first_rank producer). Part of #526.

**Defect.** `! all N hits are session-transcript copies — no curated document matched`
is a claim about the STORE; the measurement was of the RETURNED SET. In wing 2g the
curated layer begins at rank 14-27, so at `--limit 3` the sentence was true of the
result and false of the corpus, and two sessions concluded the project had nothing.

**Change.** One banner, three cases, keyed on `curated_first_rank` from #534:

| result object | banner |
|---|---|
| curated ranked inside the limit | (nothing about curation) |
| curated promoted from rank K | `! 1 curated hit promoted from rank K; the curated layer in this wing begins there — widen the pool with --limit 30` |
| none within the deep fetch (`curated_first_rank: null`) | `! no curated document in the top N` — no rank clause, no K exists |

"Widen the pool" is the mechanism (#534: the limit sizes the hybrid fusion candidate
pool), not "scroll further".

**Producer/consumer pair, one test.** `tests/test_search_banner_contract.py` drives one
result object from the field to the rendered line for all three cases and asserts
printed K == `--json` K at 14 and 27. Negative: the phrase "no curated document
matched" is asserted ABSENT. The banner is only reached when `results` is non-empty,
so an error payload cannot print it (PR 4 hardens the error path itself).

**Blast radius.** `_print_search_header` (cli.py), `all_transcript` docstring
(provenance.py — no production caller now, kept + tested), 3 #477 banner tests updated
to the new wording. No JSON field changes.

**Verification.** Rebased onto 69fd30c (#534 squash): full suite 7559 passed / 82 skipped / 1 failed — the one failure was `test_quiet_suppresses_the_banner`, whose substring `promoted from rank` now also matches the per-hit marker #534's PART 44 fix added to the table renderer; sharpened to assert the banner SENTENCE is absent under `--quiet` and the per-hit marker survives (quiet strips chrome, not provenance). After: banner contract 8/8 + depth 16/16; ruff check + format clean; check-docs clean (see entry commit). Order note: lands after #536 and #541 in the cli.py queue — expect one generated-only rebase at go.
