From 70a9a6128e2a787dc93f4ed2daa7b4f8a4f9e743 Mon Sep 17 00:00:00 2001 From: phenomenon0 Date: Sat, 20 Jun 2026 20:45:29 -0500 Subject: [PATCH 1/2] =?UTF-8?q?fix(glyph):=20release-readiness=20=E2=80=94?= =?UTF-8?q?=20number=20parity,=20patch=20base,=20CI=20fail-closed,=20doc?= =?UTF-8?q?=20reconciliation?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the external review's release blockers (reviewed at 95f868f). - Numbers: unify Python JSON-domain number typing to Go/JS via a safe-integer window in from_json_loose (integer-valued |n|<=2^53-1 -> int, else float64). Golden corpus 51/51 with 0 xfail; byte-identical across Go/Python/JS (all_impl_parity 24/24). canon_float untouched. - Patch base: Python now records/parses @base= and gains verify_patch_base / compute_base_fingerprint, standardized on the no-tabular state fingerprint (= fingerprint_loose[:16], the README invariant). The previously dormant Go TestTripleImpl_PatchParse is live and now checks Go<->Python<->JS base parity (canon.py and canon.mjs both emit baseFingerprint). _parse_path accepts the bare Go/JS path form so Python can parse their patches. - README: replace the unparseable @ops=[...] patch example with real syntax that parses identically in Py/JS/Go; correct the prose (no false JS standalone verifyPatchBase claim — JS enforces base via the GS1 cursor). - CI: remove silent `|| true` from the typechecks and the npm publish build (fail closed); add a release-meta job so a v* tag publishes only the registry whose package version matches the tag (no blind PyPI+npm fan-out). - Tests: tests/conftest.py excludes the three cross-impl scripts so `pytest tests/` is clean (no fixture errors / return-value warnings); the scripts still run and pass; stale vectors corrected to Go golden truth. - Docs: reconcile the float rule to one authoritative source (CANONICAL_FORMS §3) with the verified exp<=-5/>=6 boundary and a loose-vs-typed layer note; remove the stale "open divergence / threshold rule / known canonFloat bug" claims now that the rule is verified byte-identical. - cogs: default `go build`/`go vet` are clean; document that the cowrie require is dev-only and breaks external `go get` until cowrie is published or cogs is extracted to its own module (structural decision deferred). gitignore the AI context dumps.

Harness (gauntlet/scenarios/): - gen_inputs.py -> inputs.json: single shared fixture source (same conditions) - runner.py / runner.cjs / go/cmd/gauntletrunner: per-language evidence runners (measure only; the orchestrator is the single evaluator) - gauntlet.py: runs all three, applies criteria incl. byte-for-byte cross-lang equality, writes report.json, exits non-zero on any failure Scenarios: S1 JSON bridge - S2 canonicalization - S3 fingerprint parity - S4 tabular compaction - S5 patch apply - S6 patch-base fail-closed - S7 GS1 framing + wire parity - S8 streaming firewall. First run was 6/8. Both failures were cross-language divergences where Go and JS agreed and Python was the outlier; fixed Python to match Go (source of truth): - Tabular header: emit `@tab _ rows=N cols=M [cols]` and accept it on parse (py/glyph/loose.py, py/glyph/parse.py). Python previously could not read Go/JS tabular output. - Patch @base: compute over canonicalize_loose, not the no-tabular fingerprint, matching Go/JS and LOOSE_MODE_SPEC (py/glyph/patch.py); reconcile the README invariant block accordingly. Result: 8/8. Existing suites stay green (py 444, py-gauntlet 81, go all, js 579, cross-impl parity gate all). Also lands in-progress branch work already staged in the tree: the per-language gauntlet tests (go/py/js), the JS loose-text parser (parse_loose.ts), the gauntlet web demo, and release-readiness doc updates.

A three-level evaluation of the cowrie-glyph codec
+

The Glyph Gauntlet

+

+ Three levels: does it round-trip, does it obviously beat JSON, and by how many bytes? +

+

All numbers computed live from the real cowrie-glyph codec — no values fabricated.

+

Correctness Gauntlet

+

Museum of edge cases — every record encoded from JSON to glyph by the real codec. Round-trip status is honest about the JS loose-text gap.

Dramatic Demos

+ + +
+
+ Act I +

Tool-Call Firewall LIVE

+
+

Stream a glyph tool-call char-by-char through the real StreamingValidator. Watch it detect the tool name, then accept or reject.

Click a button to stream a tool call...

Same data, different formats. canonicalizeLoose() auto-tabularizes (autoTabular=true, minRows=3).

Corruption & Resync CONCEPTUAL

+
+

Frame integrity via CRC-style markers. One flipped byte corrupts the frame; the receiver detects, rejects, and resyncs to the next @ sentinel.

+ +
+
+
+ OK +
+
@patch @keys=wire @target=match:001
+
Frame header — known sentinel, valid
+
+
+
+ ERR +
+
+ = minute 4X +
+
Bit-flip at byte 34 — CRC mismatch, frame rejected
+
+
+
+ SKIP +
+
= score_home 1
+
Remaining bytes in corrupted frame discarded
+
+
+
+ SYNC +
+
@end
+
Next @ sentinel found — stream resynced, next frame accepted
+
+
+
+
+ Not yet measured in the harness. Diagram shows the designed behaviour of the StreamingValidator sentinel-based recovery. +
+
+
+
+
+ + +
+
+
Level 3
+

Benchmark Cook-Off

+

Four datasets, three formats. Bytes and estimated tokens (heuristic — see footnote).

+ + +
+ + + + + + + + + + + +

Token savings figures are illustrative only — heuristic whitespace tokenizer, not BPE. Use tiktoken for accurate comparisons.

Summary

Scorecard & Methodology

+ +
+
+
Checklist
+
    +
  • ✓Correctness: 14 edge cases encoded from real codec
    • +
  • ✓Compression: >60% byte savings on repeated-row tabular data
    • +
  • ✓Streaming: real emitPatch() output measured vs full snapshots
    • +
  • ✓Firewall: StreamingValidator rejects unknown tools before stream ends
    • +
  • ✓JS loose round-trip closed: parseLoose() inverts canonicalizeLoose (parity with Go/Py); all 14 edge cases round-trip
    • +
  • !Token savings are heuristic (whitespace tokenizer, not BPE)
    • +
  • !Bundle uses crypto — fingerprintLoose() throws in pure browser context
    • +
