From b63473bb65138eb4cf70e08567e10df15081fb72 Mon Sep 17 00:00:00 2001 From: Robert Gering Date: Mon, 27 Jul 2026 14:45:03 +0200 Subject: [PATCH 1/7] Fan external voices out per lens cluster (0.7.0) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit codex and grok no longer run one broad multi-lens review each — they fan out over the SAME gated lens clusters as the Claude finders (one call per cluster; per lens under --max). The gate now prunes calls for everyone: a fully-gated-out cluster spawns nothing for any voice. - New adapter flag `agents.sh run --lens-instr ` prepends the workflow-supplied cluster briefs to the fenced-diff prompt in deterministic shell — the same "assembly is never an LLM step" contract the diff fencing follows, and backend-agnostic, so a future voice inherits per-cluster prompts for free. - LENS_BRIEF becomes single-source in swarm-review.js: the SKILL.md external-prompt HDR drops its hand-mirrored lens list. test_lens_sync.py flips that mirror check to a negative one and pins the --lens-instr wiring on both sides. - Lens tags become authoritative (the voice IS its cluster); an untagged finding from a single-lens external unit now resolves to that lens instead of falling back to 'unspecified'. - --max lifts every voice to per-lens granularity (previously Claude only). A claude:false control run keeps full-width external coverage. - Cost is logged at fan-out (live-backends × units, <=2x4 default, <=2x11 under --max) and never silently capped; an all-pruned gate logs why no external call ran. - Skill oversize threshold drops to 118784 B (4 KiB under the adapter cap) since exec now sees instruction + diff; briefs are asserted apostrophe-free and shell-quoted for the transport command. Grok needs no diff-only brief variant: since 0.6.0 both externals read project files, so both get the full cluster briefs.

Applying the agreed ones: Gate blast radius (the critical finding). With externals gated too, a lens the low-effort haiku gate drops is now reviewed by NOBODY — the full-width external calls used to absorb a mis-gate, and the gate's only other protection is a sentence in its own prompt, i.e. injection-reachable via the diff it classifies. Add MANDATORY_LENSES (security, adversarial) as a code-level floor the gate cannot prune. Also materialize lenses the gate lists in neither `run` nor `skip` into `skip`, so the report can't under-report what was pruned — the self-review run silently dropped `adversarial` exactly this way. - agents.sh: reject a present-but-EMPTY --lens-instr instead of silently running a lens-free review whose findings the workflow still labels with the cluster's lenses (mislabeled coverage is worse than a hard error). An omitted flag stays legal for ad-hoc calls. Self-contained usage text; size messages render the limit from max_bytes instead of a hardcoded "120 KiB". - One unitBrief() now feeds both the Claude finder prompt and lensInstr(); the externals reuse finderUnits whenever a gate ran, so the two sides cannot drift. - backendErrors carry the unit + its lenses: every backend is multi-voice now, so "codex errored" alone hid WHICH cluster lost coverage. - LENS_BRIEF guard also rejects newlines/tabs/control chars — the transport command's one-line property depended on it. - SKILL.md: --max documented as splitting EVERY voice per lens (<=22 external calls), not just Claude; the external HDR is now lens- AND kind-agnostic, so a defect-only cluster is no longer invited to report design improvements. - test_lens_sync.py pins the skill's oversize threshold against the adapter's max_bytes and the largest instruction the briefs can produce. - Stale docs corrected: the workflow's drift warning and gate comment, the plugin.json description (now equal to marketplace.json), the README adapter synopsis, and the knowledge entry (per-cluster externals shipped, with the assembly/floor rationale recorded). Not applied: passing the instruction as a file payload (nobody can write that file — the workflow sandbox has no FS and the skill's prep runs before the gate exists; handing the write to the transport agent is the rejected LLM-assembly option), and keeping one external voice ungated (that would undo the cost control the per-cluster split exists for).

Two cross-family findings hit the previous commit's own hardening: - MANDATORY_LENSES is an explicit list, i.e. a MIRROR: renaming a lens in LENS_CLUSTERS would leave a stale entry that can never match, silently voiding the floor while every check stayed green. Assert the subset at startup and pin it in test_lens_sync.py (proven: a rename now fails CI). Kept explicit rather than derived from LENS_CLUSTERS.threat — which lenses are non-negotiable is a judgement call, not a consequence of cluster membership. - The gate coverage rewrite copied the gate's `skip` entries verbatim, so a hallucinated lens name ("typo") would render as a gated-out lens that does not exist. Filter skip to known lenses and assert run/skip stay disjoint as well as complete. - New `--lens-instr-bytes`: the empty-value check only caught a TOTAL loss, so a transport that shortened or paraphrased the instruction still ran and had its findings attributed to lenses the backend was never told to review — quietly hollowing out "the voice IS its cluster". The caller declares the byte count it built; a mismatch is a hard error. Length is computed in pure JS (the workflow sandbox has no Buffer/TextEncoder; verified to match Buffer.byteLength on multi-byte input) and memoized so command and count describe one build. - Corrected an overstatement I wrote: the floor guarantees cluster SPAWN, not lens coverage — within `breakage` the gate may still prune removed-behavior / cross-file-trace, leaving that unit at lenses:['correctness'] for every voice. Disclosed via gated-out, but "breakage ran" != "deletions were reviewed". - Stale docs: README gate bullet (Claude-only pruning, skippable security), knowledge isolation paragraph (per-voice now), miscounted list intro. - Recorded the two repeatedly-refound-but-declined items (prose oversize gate, per-unit grok probe) as accepted residuals with reasons, so later rounds see them as decided rather than overlooked. Not applied: widening the floor to the methodological lenses — that is the same cost/coverage tradeoff the user already ruled on once, and the pruned lenses are reported.

"Any edit changes the length" is false: `security` → `altitude` and `ONLY` → `ALSO` are same-length swaps that change the review scope while the count still matches, so a garbled retype would run and still be credited as a threat review. Replaced by `--lens-instr-sum`, an FNV-1a/32 over the instruction's UTF-8 bytes — pure JS in the workflow (the sandbox has no Buffer/crypto/TextEncoder), recomputed in python3 by the adapter, verified bit-identical across ASCII, umlauts, em dashes and emoji. Non-cryptographic on purpose: the threat is an LLM mangling a retype, not a collision search. - The check was also opt-out by omission — dropping `--lens-instr-bytes` while truncating the instruction skipped it entirely. The checksum is now REQUIRED whenever `--lens-instr` is present; only a fully lens-free ad-hoc call stays legal. Both holes covered end-to-end (same-length swap, missing checksum, malformed checksum, ad-hoc call). - Oversize skip is now decided in the prep Bash (`EXTERNALS_OVERSIZE`) rather than by model arithmetic — the skill's own `--pr`/`--fix` guard already sets that pattern, and a compaction could otherwise let live voices through and turn one clean skip into N per-call backend errors. test_lens_sync.py now pins the threshold from that executable guard, not the prose. - The gate prompt named only `security` as non-skippable while the code floor holds three lenses; it now interpolates MANDATORY_LENSES (one source). - Fan-out error log names the failing UNIT, not just the backend. - Stale docs: knowledge said externals are diff-only (0.6.0 gave them file-read + web; the residual reason design clusters are verified is correlation, not blindness), README adapter block missed the new flag. Not applied: caching grok's per-unit model probe — the calls run in parallel, so the cost is redundant network work, not wall-clock, and a cache adds staleness.

The SKILL.md external-prompt HDR drops its hand-mirrored lens list; `test_lens_sync.py` flips that mirror check to a negative one and pins the `--lens-instr` wiring. - **Mandatory-lens floor.** Because the gate now prunes for every voice, a lens it wrongly drops is reviewed by nobody — the old full-width external calls used to absorb that, and the gate's only other protection is a sentence in its own prompt (injection-reachable via the diff it classifies). `MANDATORY_LENSES` (`security`, `adversarial`, `correctness`) can never be pruned; accepted cost is that the `breakage` and `threat` clusters always spawn, leaving the gate only `design`/`consistency` to prune. The report's coverage line now partitions the full lens set: floored-in lenses are written back to `gate.run`, and lenses the gate listed in neither field are materialized as gated-out (a live run silently swallowed `adversarial` this way). +- **Transport integrity is content-bound.** `--lens-instr-sum` (FNV-1a/32 of the exact instruction, computed in pure JS by the workflow and recomputed in python3 by the adapter) replaces the first attempt at a byte-length check — `security`/`altitude` and `ONLY`/`ALSO` are same-length swaps that change the review scope while a byte count still matches. It is **required** whenever `--lens-instr` is given, so a transport cannot void the guard by dropping one flag. The prep block now also decides the oversize skip deterministically (`EXTERNALS_OVERSIZE`) instead of leaving the arithmetic to the model. - **Transport integrity for the lens instruction.** An empty `--lens-instr` was already refused; `--lens-instr-bytes` now also rejects a *paraphrased or truncated* one, so a backend can never review a narrower scope than its findings are labelled with. `MANDATORY_LENSES` is asserted to be a subset of the lens set at startup and in CI (an explicit list is a mirror: a renamed lens would silently void the floor). The gate coverage line drops hallucinated lens names and asserts run/skip stay disjoint. - The `--max` profile now lifts **every** voice to per-lens granularity (previously Claude only). A `claude: false` control run keeps full-width external coverage (no gate exists to prune it), just split per cluster. - Grok no longer needs a diff-only brief variant: since 0.6.0 both externals read project files, so both get the full cluster briefs. diff --git a/plugins/swarm/README.md b/plugins/swarm/README.md index 0e38c7c..225124a 100644 --- a/plugins/swarm/README.md +++ b/plugins/swarm/README.md @@ -121,13 +121,18 @@ agents.sh available # installed? prints version agents.sh ready # authenticated? hint on stderr if not agents.sh jail # jail=yes|no — will read+web be granted?

A one-sided edit would make every external call fail its own integrity check: exit 2 per unit, the whole external half of the ensemble collapsing into backendErrors while Claude still runs. Both sides are now run against a reference implementation of the FNV-1a spec, using their real source (the adapter's own inlined python snippet, the workflow's extracted function under node) rather than copies. Mutation-tested: changed prime, dropped zero-pad, broken 3-byte UTF-8 path, changed offset basis and dropped overflow mask are all caught. The zero-pad case needed a deliberate vector — "f8" hashes to 0d226273, the only one of the set with a leading zero. Without it a dropped `padStart` passed while the two sides genuinely disagreed on short hashes. - CHANGELOG kept both the superseded byte-count bullet and its replacement, so 0.7.0 documented a `--lens-instr-bytes` flag the adapter does not implement. Replaced with the gate-floor/coverage-line entry it should have been. - Knowledge heading still said "guarded by length, not trust" while its own body and the code describe the content checksum. Not applied: replacing the argv transport with a file payload (precluded — the workflow sandbox cannot write and the prep runs before the gate exists; the verifier reached the same conclusion), and resolving grok's model probe once per backend instead of per unit — the calls run in parallel, so it costs redundant network round-trips, not wall-clock. Standing accepted residual.

The report's coverage line now partitions the full lens set: floored-in lenses are written back to `gate.run`, and lenses the gate listed in neither field are materialized as gated-out (a live run silently swallowed `adversarial` this way). - **Transport integrity is content-bound.** `--lens-instr-sum` (FNV-1a/32 of the exact instruction, computed in pure JS by the workflow and recomputed in python3 by the adapter) replaces the first attempt at a byte-length check — `security`/`altitude` and `ONLY`/`ALSO` are same-length swaps that change the review scope while a byte count still matches. It is **required** whenever `--lens-instr` is given, so a transport cannot void the guard by dropping one flag.
