From 4ad7fc33517e2bd5866dad103378b2dd1e3ac743 Mon Sep 17 00:00:00 2001 From: "Charles C. Figueiredo" Date: Sun, 13 Sep 2026 22:25:57 -0400 Subject: [PATCH 01/26] Add v0.2 design spec Grammar/repetition scanner layer, apostrophe-glyph fix, rewrite guards, fairness principle, three new surface tells, SOURCES.md provenance, and a fixture gate for every new metric. Scope per the research review short list.

The +research review found four layers that corpus does not cover and one live +scanner defect. v0.2 adds the cheap, well-evidenced parts of those layers, +makes the evidence base citable without weakening the base-rate invariant, and +adds the fairness rail the review identified as the single largest gap. + +### Goals + +1. Fix the apostrophe-glyph defect that makes every scanner rate wrong on real + model output. +2. Add a grammar/repetition layer to the scanner: verbatim repetition, trailing + participial clauses, container-noun phrases, nominalization hits, and + sentence-length tail/sequence statistics. +3. Add two rewrite guards to the skill: do not strip passives by reflex; check + for convergence after rewriting. +4. Add the fairness principle ("register and proficiency are not tells") and + the adjudication rule ("check the direction before you flag it"). +5. Add three surface-tell entries (safety-disclaimer opener, container-noun + phrase, nominalized verbs), extend two, and date-stamp the wordlist. +6. Add `references/SOURCES.md` and amend the provenance invariant so numbers + from sources other than StoryScope can be cited on `Scan:`/`Why` lines. +7. Gate every new metric on the plugin's own fixtures, including a new formal + human text that must not read as a verdict. + +### Non-goals (deferred from the review, by decision) + +`--by-paragraph` hotspots and `--halves`; contraction and connective blocks; +`FICTION_PHRASES`; a separate `grammar-tells.md`; `adverbs.ly_rate`; MTLD or +any lexical-diversity check; per-model grammar quirks; anything that labels a +passage as model-written. Detector evasion remains out of scope. + +## 1. Scanner (`plugins/humanize/skills/humanize/scripts/surface_scan.py`) + +Stdlib only, Python 3.9. `analyze()` keeps every existing key unchanged; new +keys are added. Every new block reports numbers and quotable hits, no verdicts. + +### 1a.

The rewrite splits the participial +tails into sentences with their own subjects, cuts the repeated phrase to one +instance, names the concrete thing behind each container noun, and leaves the +nominalizations that the register earns.

I'm not able to share vendor pricing here, but the overall picture is encouraging and the risks are manageable. + +The implementation of the new ingestion pipeline finished two weeks behind the original estimate, reflecting the late discovery of schema drift in the partner feed. The team resolved the drift by introducing a validation layer, ensuring alignment across teams before any record reaches the warehouse. Throughput now sits at roughly nine thousand events per minute, exceeding the target we set in March. + +Adoption of the shared design system continued across all workstreams and teams, creating a sense of momentum that was missing last quarter. Four product surfaces migrated to the new components, allowing designers to retire eleven legacy patterns. The migration of the billing screens remains in progress, pending the completion of an accessibility review. + +On the reliability side, the optimization of our alerting rules reduced paging volume by about a third. Engineers consolidated forty-two overlapping alerts into nine, giving on-call staff a clearer signal during incidents. Mean time to acknowledge fell from eleven minutes to four, matching the level the platform group had proposed. + +Customer support handled a spike in tickets after the pricing change, resolving most of them within the first business day. The knowledge base articles were rewritten in plainer language, and the deflection rate climbed from thirty to forty-one percent. A small group of enterprise accounts asked for a dedicated onboarding call, and account managers have scheduled those for the second week of the month. + +Hiring closed on three of the five open roles, leaving two senior positions unfilled going into the next cycle. The weight of the decision to pause backfills fell mostly on the data platform group. We expect the remaining offers to close by mid-month, assuming the compensation adjustments are approved. + +Coordination across all workstreams and teams improved once the weekly sync moved to a written format. Fewer meetings meant more focused work, and the written record made the escalation of blockers faster to trace. Product managers reported that the transformation of the roadmap into quarterly themes made prioritization discussions shorter. + +Security completed the remediation of the findings from the spring audit, closing every high-severity item ahead of schedule. Two medium items remain open, awaiting a library upgrade that the vendor has scheduled for next month. The compliance team confirmed that the evidence collection process now runs automatically each week. + +Documentation for the public API moved to the new site, giving external developers a searchable reference for the first time. Traffic to the reference pages doubled in the first month, and the volume of questions in the developer forum dropped noticeably. The technical writers also produced a migration guide for teams still on the deprecated endpoints. + +Looking ahead, the integration of the analytics events into the new pipeline is the main dependency for the reporting launch. The team plans to finish the mapping by the end of the month, leaving three weeks for validation with finance. Budget remains within the approved envelope, and no additional headcount is requested at this time. + +In summary, delivery across all workstreams and teams stayed on plan despite the schema issue, and the quarter closes with fewer open risks than it opened with.

The friend of popular governments never finds himself so much alarmed for their character and fate, as when he contemplates their propensity to this dangerous vice. He will not fail, therefore, to set a due value on any plan which, without violating the principles to which he is attached, provides a proper cure for it. The instability, injustice, and confusion introduced into the public councils, have, in truth, been the mortal diseases under which popular governments have everywhere perished; as they continue to be the favorite and fruitful topics from which the adversaries to liberty derive their most specious declamations. The valuable improvements made by the American constitutions on the popular models, both ancient and modern, cannot certainly be too much admired; but it would be an unwarrantable partiality, to contend that they have as effectually obviated the danger on this side, as was wished and expected. Complaints are everywhere heard from our most considerate and virtuous citizens, equally the friends of public and private faith, and of public and personal liberty, that our governments are too unstable, that the public good is disregarded in the conflicts of rival parties, and that measures are too often decided, not according to the rules of justice and the rights of the minor party, but by the superior force of an interested and overbearing majority. However anxiously we may wish that these complaints had no foundation, the evidence, of known facts will not permit us to deny that they are in some degree true. It will be found, indeed, on a candid review of our situation, that some of the distresses under which we labor have been erroneously charged on the operation of our governments; but it will be found, at the same time, that other causes will not alone account for many of our heaviest misfortunes; and, particularly, for that prevailing and increasing distrust of public engagements, and alarm for private rights, which are echoed from one end of the continent to the other. These must be chiefly, if not wholly, effects of the unsteadiness and injustice with which a factious spirit has tainted our public administrations. + +By a faction, I understand a number of citizens, whether amounting to a majority or a minority of the whole, who are united and actuated by some common impulse of passion, or of interest, adversed to the rights of other citizens, or to the permanent and aggregate interests of the community. + +There are two methods of curing the mischiefs of faction: the one, by removing its causes; the other, by controlling its effects. + +There are again two methods of removing the causes of faction: the one, by destroying the liberty which is essential to its existence; the other, by giving to every citizen the same opinions, the same passions, and the same interests. + +It could never be more truly said than of the first remedy, that it was worse than the disease. Liberty is to faction what air is to fire, an aliment without which it instantly expires. But it could not be less folly to abolish liberty, which is essential to political life, because it nourishes faction, than it would be to wish the annihilation of air, which is essential to animal life, because it imparts to fire its destructive agency. + +The second expedient is as impracticable as the first would be unwise. As long as the reason of man continues fallible, and he is at liberty to exercise it, different opinions will be formed. As long as the connection subsists between his reason and his self-love, his opinions and his passions will have a reciprocal influence on each other; and the former will be objects to which the latter will attach themselves. The diversity in the faculties of men, from which the rights of property originate, is not less an insuperable obstacle to a uniformity of interests. The protection of these faculties is the first object of government. From the protection of different and unequal faculties of acquiring property, the possession of different degrees and kinds of property immediately results; and from the influence of these on the sentiments and views of the respective proprietors, ensues a division of the society into different interests and parties. diff --git a/tests/fixtures/human_plain.txt b/tests/fixtures/human_plain.txt new file mode 100644 index 0000000..2045bb7 --- /dev/null +++ b/tests/fixtures/human_plain.txt @@ -0,0 +1,97 @@ +One of the most popular plain language myths is that you have to “dumb down” your content so that everyone can read it.

Here are some general tips to help you identify your users. + +There are many techniques to help you learn about your users. For more details and best practices, visit usability.gov. + +Understanding what users are trying to do when visiting your website or reading your communications will help you write clearly and focus on their needs. + +Think about how well your communications support people in getting things done. People come to government websites and services with a specific task in mind. If your content doesn’t help them complete that task, they’ll get frustrated and potentially leave. + +You need to identify the purpose of your website to help clarify the top tasks it should help people accomplish. + +Even though your document may affect a thousand or a million people, you are speaking to the one person who is reading it. When your writing reflects this, it’s more economical and has a greater impact. + +When you use “you” to address users, they are more likely to understand what their responsibility is. + +It’s especially important to define “you” when writing to multiple audiences. + +If you use a question-and-answer format, you should assume that the user is the one asking the questions. Use “I” in the questions to refer to the user. Use “we” in the responses to represent your agency. + +By using “we” to respond to questions, you state clearly what your agency requires and what your agency’s responsibilities are. Using “we” makes your agency more approachable and also helps you use fewer words. You can define “we” in the definitions sections of your document if that will help the user. + +You can avoid awkwardness by using “you” to address the reader directly, rather than using “he or she” or “his or her.” + +Make sure you use pronouns that clearly refer to a specific noun. If a pronoun could refer to more than one person or object in a sentence, repeat the name of the person or object or rewrite the sentence. + +Use singular nouns and verbs to prevent confusion about whether a requirement applies to an individual or several groups. In the following example, the user might think that they need to file applications at several offices. + +For more details on addressing multiple users, see Address separate audiences separately. + +An important part of writing for your audience is addressing separate audiences separately. Many documents and websites address more than one audience. Mixing material intended for different audiences may confuse readers. By addressing different audiences in the same place, you make it harder for each audience to find the material that applies to them. In regulations, this may make it difficult for each audience to comply with your agency’s requirements. + +The following example shows a regulation (40 CFR 745) that treats each regulated group separately in its own subpart, rather than mixing all the groups together. For an example of a rule that does not address separate groups separately, see 5 CFR 1320. + +Organization is key. Start by stating your purpose and the bottom line. Lay things out in a logical order. Put the most important information at the beginning and include background information (when necessary) toward the end. + +People read government websites and documents to get answers. They want to know how to do something or what happens if they don’t do something—and they want to gain this knowledge quickly. Organize your writing so it’s easy to follow along. + +Think through the questions your users likely have and then organize the material in a logical order. + +For regulations and other complex documents, create a comprehensive table of contents. Your table of contents should be a reliable roadmap that users can follow to quickly find what they need. + +Present the steps chronologically, in the order your user and your agency will follow them. The table of contents below is organized in a logical sequence for a grant program. + +Another useful organizing principle is to put general information first, and specialized information or exceptions later. That way, the material that addresses most readers in most situations comes first. For some documents this will work well along with a chronological organization. In others, it may be the primary organizing principle. + +Crafting documents with four, five, or even more levels makes it difficult for your audience to keep track of where they are in the process. You should address this problem in your initial structuring of the document. + +If you tell your reader what they’re going to read about, they’re less likely to have to read your paragraph again. Headings help, but they’re not enough. Establish a context for your audience before you provide them with the details. If you flood readers with details first, they become impatient and may resist hearing your message. A good topic sentence draws the reader in. + +A side benefit of good topic sentences (and good headings) is that they help you see if your document is well-organized. If it isn’t, topic sentences make it easier for you to rearrange your material. + +Start with your main idea – not an exception. + +When you start a sentence with an introductory phrase or clause beginning with “except,” you almost certainly force the reader to reread your sentence. You are stating an exception to a rule before you have stated the underlying rule. The audience must absorb the exception, then the rule, and then usually has to go back to grasp the relationship between the two. Material is much easier to follow if you start with the main idea and then cover exceptions and conditions. + +In the first version, the audience has to decide whether to jump immediately down to paragraph (b) or continue reading to the end of the sentence.

Figueiredo" Date: Mon, 14 Sep 2026 00:26:06 -0400 Subject: [PATCH 12/26] Rebuild human_plain.txt with mechanical extraction only, no sentence exclusions Fixture content must not depend on the metric under test. Rebuilds human_plain.txt using only the stated mechanical rule (paragraphs under 8 words, list lead-ins, and boilerplate dropped) in page order, truncated at the first paragraph crossing 600 words, with no sentence-level curation. The honest fixture lands at participial_tail.count == 1, exactly at the specificity cap, so no metric report is needed. Re-pins all human_plain.txt bands in PROVENANCE.md and test_fixtures.py from the new measurements.

Still exactly 150 lines. - surface-tells.md: drop the uncited "fivefold within a year" magnitude from the Vintage line; kobak-2025's registry entry licenses the decay note only, not a figure (issue 5). - CLAUDE.md / .cursor/BUGBOT.md: add Vintage: to the permitted number-bearing lines so the shipped wordlist entry stops contradicting the invariant it's supposed to satisfy; update the test-count comment. - README.md: list disclaimer opener among the scanner's blocks (issue 11). - CHANGELOG.md: note the 60-token phrase cap, the SKILL.md line-budget test, Rule of thumb: and Vintage: in the provenance bullet, and that apostrophe normalization shifts words/wordlist.rate/per-1k rates on text with look-alike glyphs (issue 12). - Design spec: mark it "post-review amendments at the end" and append a Post-review amendments section recording every ruling above plus the measured (not illustrative) fixture figures.

The prefix is segmented on its own first comma: the resulting opener decides whether a skip is on the table at all (subordinator / conjunctive-adverb / verbless-preposition, as before), and whatever follows that comma is checked for a finite verb (now including a new IRREGULAR_PAST list) to catch a complete second clause already under way, in which case the -ing word is a genuine trailing participial rather than the opener's gerund subject. - PREP_SUB gains "without" per the brief's updated extension list.

Figueiredo" Date: Mon, 14 Sep 2026 02:13:55 -0400 Subject: [PATCH 21/26] Revise A7 (segment-based guard), fix A8 en-dash ranges, A10 gram-run merge MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - A7 REVISED: the whole-prefix finite-verb veto from the prior commit regressed "In most quarters, revenue rises, lifting margins." from a hit to a miss (present-tense finite verbs aren't -ed/FINITE_AUX/IRREGULAR_PAST). _is_fronted_adverbial now splits the prefix into ", "-delimited segments: the first segment must be opener-led per A3 (subordinator / conjunctive adverb / preposition); every later segment must be opener-internal (one word, e.g. "Texas", "2024", or itself preposition-led, e.g. "with 1,200 users") or the guard lifts, since a multi-word non-prepositional segment ("revenue rises", "the team grew") is a clause of its own. The verbless finite-verb veto (now including IRREGULAR_PAST) still runs over the whole prefix, but only for the preposition-led-first-segment branch. - A8: en dash now terminates a clause only when followed by whitespace (`–(?=\s)`), so a numeric range like "2023-2024" (en dash) inside a participial tail is no longer truncated mid-range; " – then rested" still terminates as before. - A9 confirmed: PREP_SUB already includes "without" (added in the prior commit, ahead of this brief update). - A10: repeated_phrases now merges runs of overlapping cap-length (60-token) grams sharing the same count and sentence set, collapsing sliding-window duplicates of one verbatim repeat longer than 60 tokens into a single representative phrase instead of counting each window separately. - B1 REVISED: test_sources_registry_exists_with_expected_keys now splits SOURCES.md only on the backticked key-heading form ("## `"), not any line starting with "## ", and asserts every expected key is present before indexing, closing both the truncation risk and the IndexError risk in the prior fix. Re-ran all five fixtures with A3+A6+A7(revised)+A8+A9+A10 together: participial_tail.count unchanged (ai_report.txt 14, human_formal.txt 0, human_plain.txt 1, ai_email.txt 0, human_email.txt 0); repetition rates on all five fixtures also unchanged, since none contains a repeat anywhere near the 60-token cap. Known discrepancy, not resolved here: A10's own explicit test (two identical 100-word sentences -> one phrase, count 2) passes exactly as specified. Its second required test -- the A2 probe (an 8-word phrase repeated 50 times) reporting repeated_phrase_rate < 50 -- does not pass (measured 1012.5, down from 1637.5 before this fix, a genuine ~38% reduction). That probe is periodic at every divisor of 8, producing a "staircase" of same-content grams at lengths 8, 16, 24, ... each with a different, decreasing count; A10's merge is explicitly scoped to length-exactly-60 grams sharing the same count, so it cannot touch this staircase, and the shortest rung alone (the 8-word unit itself, genuinely occurring 50 times) already yields a higher rate than the threshold regardless of merging. Reported in full in final-fix-report.md rather than adjusting the test or inventing broader, unauthorized merge logic.

Appends one bullet each: - A6: the (?!-) lookahead excluding hyphenated -ing compounds as clause heads. - Revised A7: the segment-based opener guard (first segment opener-led, every later segment opener-internal or the guard lifts), IRREGULAR_PAST joining the finite-verb veto, and the two known/accepted residual false positives deferred to v0.2.x. - A8: en dash terminating a clause only when whitespace follows it. - A10: merging overlapping cap-length gram windows of one long repeat into a single phrase. CHANGELOG.md's grammar-block Added bullet is generic (no rule details), so per the brief's addendum it is left unchanged.

Pruned to the 67 unambiguous past forms the brief names, adding "sought" and "caught" which the pruned list newly requires. Bugbot's companion finding (present-tense remainder after an opener, comment 4002562244) needs no new code: the revised A7 segment rule already handles it, confirmed with "In practice, this approach reduces friction, enabling teams to move faster."

Figueiredo" Date: Mon, 14 Sep 2026 02:36:44 -0400 Subject: [PATCH 24/26] Prune six more IRREGULAR_PAST homographs; fix a coincidental -ed match A12 (re-review rounds 2-3): four more words on the A11 keep-list read as common nouns/adjectives in ordinary openers -- felt (wool felt), thought (on second thought), stole (fur stole), fell (one fell swoop) -- plus borderline spent (spent grain/fuel) and led (lowercased "LED"). Removed all six; IRREGULAR_PAST is now 61 words. Removing "led" alone was not sufficient: _has_finite_verb's generic `t.endswith("ed")` check independently matched "led" regardless of IRREGULAR_PAST membership, since it makes no length distinction. Narrowed that check to words longer than 3 characters -- no genuine English regular past tense is 3 letters (that would require an impossible 1-letter base verb), so this excludes "led" (and "red"/"bed"/"wed"/"fed" as a side effect) without excluding any real regular past tense, which needs at least a 2-letter base ("used"). Verified "In the LED aisle, shopping continued." only stopped firing after this second fix; removing "led" from IRREGULAR_PAST by itself left it firing. Fallout: the A11 test's own "still fires" example, "Under the plan costs fell, driving the decision.", relied on the now-pruned "fell" and had to be updated to use "grew" instead -- the brief's own A12 "still fires" list silently dropped this exact sentence for the same reason, confirming the change is intentional, not a regression. Test: test_irregular_past_homographs_pruned_further_round_two_and_three -- all 4 new no-hit examples, plus a re-confirmation that "In March, the team grew, closing the gap." still fires. Re-ran all five fixtures: participial_tail.count unchanged (ai_report.txt 14, human_formal.txt 0, human_plain.txt 1, ai_email.txt 0, human_email.txt 0). Updated the spec's revised-A7 amendment bullet (61 words; the -ed length fix; the three v0.2.x residual openers from re-review round 2 -- "In Austin, Travis County, hiring slowed.", "More importantly, the board met, approving the plan.", "Meanwhile in Austin, shipping continued."); CLAUDE.md test count to 98.

Figueiredo" Date: Mon, 14 Sep 2026 02:43:19 -0400 Subject: [PATCH 25/26] Fix prep-led intermediate segments that hide a real clause (A13) Bugbot PR #6 comment 4002717678: in _is_fronted_adverbial, an intermediate segment starting with a PREP_SUB word was treated as opener-internal unconditionally, with no finite-verb check. So after a subordinator or conjunctive-adverb opener, a segment like "with the new vendor the team shipped faster" was swallowed as if it were mere opener-internal material (like "with 1,200 users"), and a genuine trailing participial tail was dropped: "However, with the new vendor the team shipped faster, cutting the backlog." missed its real tail. Fix: a preposition-led intermediate segment is opener-internal only when _has_finite_verb is False for it (-ed length > 3 / FINITE_AUX / IRREGULAR_PAST); if it has a finite verb, it's a clause of its own and the guard lifts, same as a non-prepositional multi-word segment already did. Single-word segments are unaffected. The first segment's own handling (subordinator / conjunctive-adverb / preposition-led-verbless) is unchanged. Known, accepted, not tested (v0.2.x general no-finite-verb rule): a present-tense clause inside a prep-led segment still misses -- "Although costs rose, in most quarters revenue rises, lifting margins." Verified by hand that this remains a miss, exactly as the brief predicts. Test: test_prep_led_intermediate_segment_with_a_finite_verb_is_a_clause -- both must-fire examples and both must-not-fire examples (the existing verbless-intermediate-segment cases, re-confirmed unaffected).

A subordinate clause always carries a verb and its comma closes it, so the following -ing word is still a gerund subject regardless of that verb -- the guard needs to stay, not lift. "However, after the audit closed, filing became routine." was firing incorrectly. Fix in the intermediate-segment loop of _is_fronted_adverbial: check SUBORDINATORS first -- a segment whose first word is a subordinator is opener-internal unconditionally, same as the first-segment rule -- then single word, then non-subordinator preposition-led-and-verbless, otherwise clause. PREP_SUB still contains words that are also subordinators (after, since, when, ...); since the SUBORDINATORS check always runs first and short-circuits with `continue`, the preposition branch is only ever reached for a genuine non-subordinator preposition, so no separate exclusion list is needed. Test: test_subordinator_led_intermediate_segment_stays_opener_internal -- both must-not-fire examples, plus a re-confirmation of A13's three must-still-fire examples to verify this fix only narrows A13's scope (stacked subordinators), not A13 itself.
