step.27.txt -- b3ubot U5.5: THE TRINITY GATE -- one full Adaptive Programming arc on the trinity: intent -> propose -> validate (real cppcc verdicts over HTTP) -> repair -> converge -> close -> deliver; egress witnessed. Phase A (the scripted leg) EXECUTED ALL-PASS this session; Phase B (the HUMAN-ADAPTER live leg) is the operator ceremony, made turnkey -- the gate, and P5, close when the ceremony's check passes. Step: 27 Parent: end_to_end.md §7 P5 U5.5 row ("THE TRINITY GATE: one full AP arc (intent -> propose -> validate -> repair -> converge -> deliver) on the trinity, mock AND live; egress witnessed"). Under the (p1) re-scope (b3u step.51 header), the LIVE leg = the HUMAN ADAPTER (the operator relaying to Claude Code) -- the accepted live path; the M1 keyed leg stays set aside. design §2.9 (the trinity), §2.5/§2.8 (the tiers + arcs this gate composes), Q-25-A (delivery placement -- RESOLVED HERE). UoW: U5.5 -- the LAST P5 UoW; closing it completes P5 and the b3ubot half of (p1). The two-phase shape is the b3u step.49 Phase A/B precedent: build+prove the machine halves now, the human half runs on the human's clock. Date: 2026-07-22 Origin: User directive 2026-07-22: "go with U5.5, step file and its execution" (the (p1) sequence). ## (0) Status PHASE A EXECUTED ALL-PASS; PHASE B PREPARED AND HANDED TO THE OPERATOR (ledger row stays `active` until the ceremony's check passes -- the honest state: a gate whose live leg is a human cannot be closed by a machine alone). Phase A (scripts/trinity_gate.sh, first invocation ALL PASS): a launcher-booted b3u; the FULL arc in a trinity workspace -- the scripted provider proposes a BROKEN grammar, the real plane answers FAIL with the genuine path-scrubbed cppcc tail, the repair re-entry carries that tail in the provider context (witnessed AT the adapter), the repaired spec converges to PASS, closure lands real commits, and the converged spec is DELIVERED (Q-25-A). The egress witness: exactly as many runs/ records as provider calls, the repair record carrying the diagnostics that left; the plane loopback-only by construction. Honest-skip twin + B-4 grep green. Phase B (scripts/trinity_ceremony.sh): `prepare` seeds a ceremony project (git ws + ledger + T3-gated skeleton at SKELETON, workspace- stamped -- rehearsed in an isolated $B3UBOT_HOME); the ceremony is `b3ubot run UC.1 --provider human` (ratify -> relay -> live T3 -> close) + `ccs generate` (deliver) + `check` -- the machine oracle that closes the gate (rehearsed against the un-run ceremony: refuses with 6 named FAILs, exit 1 -- never a fake pass). Suite 637 passed + 28 skipped = 665 collected (the 3 gate legs are env-gated live tests; measured after the last edit). PHASE B LIVE-FIRE FINDING (2026-07-22, the ceremony's FIRST real prompt -- Q-27-D): the relay's default reader was a bare one-line `input()`, while a real proposal is MULTI-line -- the operator's paste would have delivered its first line to b3ubot and spilled the rest into the shell. The operator stopped at the prompt (Ctrl-C; resumable by design); FIXED same-session: the adapter's DEFAULT input is now a sentinel-terminated multi-line reader (paste, then a line containing only EOF); injected input_fns -- every test -- keep the single-call contract unchanged. The ceremony grammar was then PRE-VALIDATED against the operator's own live plane (verdict PASS) before the relay resumed. PHASE B COMPLETE (2026-07-22, the operator at the relay): the ceremony ran end to end -- ratify (human decision), the relayed proposal (ceremony.sgr, a key/value SGDL grammar; 2 human-provider egress runs recorded), the live T3 PASS from the operator's own b3u instance, closure by the ENGINE'S OWN 2-commit shape in the ceremony repo (e270a81 work + ee71886 gdiff, hash backfilled by closing.py), and delivery (`ccs generate`, generated/ceremony/). The check oracle surfaced ONE more live-fire finding on its first real pass -- Q-27-E: its bare clean-tree leg contradicted Q-25-A (post-close delivery is necessarily untracked); fixed to "clean modulo the delivered bundle"; re-run: 8/8 PASS, independently re-verified by the engine side. THE GATE IS CLOSED: the trinity ran the Adaptive Programming loop with the human as the relay. U5.5 -> done; P5 COMPLETE; the b3ubot half of (p1) COMPLETE. ## (1) Ground truth probed at drafting (outputs -> named writers) CONFIRMED every gate ingredient existed before this step -- the tiers (U5.2/U5.3), the arcs (U5.4), the foreign shape + guard (U5.4a), the repair loop with full-tail oracle_feedback (U5.2), real closure (U3.7) -- U5.5 COMPOSES them; its own new machinery is exactly two scripts + one oracle file. CONFIRMED the egress record carries `provider` (app/egress.py) -- the ceremony check can positively identify HUMAN- relay runs (B-5's "to whom", queryable). CONFIRMED `b3ubot run` resumes from any state (M1), so a ceremony prepared at SKELETON starts at the RATIFY human gate -- the first thing the operator does is a DECISION, which is the right first beat for a ceremony about human gates. CONFIRMED the real ~/.b3ubot data home must stay clean for the real ceremony (start_state refuses duplicate UC.1) -- every rehearsal ran under an isolated $B3UBOT_HOME. ## (2) What U5.5 delivers 2.1 **Q-25-A RESOLVED: delivery is an EXPLICIT post-close arc.** Convergence = gates green = close; delivery = the operator's act of consuming the converged spec (`b3ubot ccs generate`), idempotent and re-runnable (regenerate), AFTER the evidence is frozen. NOT wired into closing.py: the close commit freezes evidence, and coupling a network delivery into it would make closure hostage to the plane's availability; pay-per-use delivery semantics belong to the operator (recorded in design §2.8-chain; the gate's own scripted leg and the ceremony both practice it). 2.2 **tests/test_trinity_gate.py** (3 live legs, Phase A's oracle): the full repair-converge-close-deliver arc with the verdict history [fail, pass] and the real tail witnessed at the adapter AND in the egress record; the egress-accounting witness (runs == provider calls; loopback plane); delivery re-runnable after CLOSED with the engine state untouched. 2.3 **scripts/trinity_gate.sh** -- Phase A's battery: boot, provision, the 3 gate legs, the honest-skip twin, B-4; prints the Phase B ceremony instructions when green. 2.4 **scripts/trinity_ceremony.sh** -- Phase B, turnkey: `prepare ` (fresh git project, T3-gated skeleton, UC.1 at SKELETON, workspace-stamped; never clobbers; refuses a duplicate UC.1) and `check ` (the 8-leg machine oracle: CLOSED, stamp, T3 rows + final PASS, clean tree, closure commits, HUMAN-provider egress runs, delivered bundle -- PASS closes the gate). 2.5 **Docs**: design Q-25-A resolution + trinity delivered-state note; end_to_end U5.5 -> active via the engine's own `ledger transition` (the amendment path again); testing.md re-measured same-commit. EXPLICITLY OUT OF SCOPE (each named, never silent): - running Phase B FOR the operator (a simulated relay would fake the exact thing the gate witnesses) -> the ceremony - relay-DRAFTING in the ceremony (V1 seeds the skeleton; the human-relayed draft stage is the named future ceremony variant -- the V0 template validation makes first-ceremony friction likely, so the first beat stays the ratify gate) -> later - the P6 agnosticism gate (a second AI provider) -> P6 (parked) - (p2)'s xml project (the trinity's first real workload) -> (p2) ## (3) Verification gates G1 PHASE A, THE ARC: propose(BROKEN) -> real cppcc FAIL over HTTP -> repair context carries the genuine tail (adapter- witnessed) -> converge(PASS) -> CLOSED with real commits, clean tree -> delivered bundle in the workspace. Verdict history [fail, pass] in verifications.jsonl. G2 PHASE A, THE EGRESS WITNESS: len(runs/) == provider calls; the repair record carries the diagnostics that left; the plane's base URL is loopback (B-2); "what left this machine, when, to whom" fully answerable from the trail (B-5). G3 PHASE A, HYGIENE: honest-skip twin (3 SKIPPED keyless); B-4 grep clean; trinity_gate.sh ALL PASS first invocation. G4 PHASE B, READINESS: prepare seeds correctly (stamp verified in rehearsal); check REFUSES an un-run ceremony with named FAILs (exit 1); both rehearsed under an isolated $B3UBOT_HOME -- the real data home untouched. G5 PHASE B, THE GATE ITSELF (OPERATOR): the ceremony run ends with `trinity_ceremony.sh check` printing PASS -- UC.1 CLOSED, final T3 PASS from the real plane, closure commits, HUMAN-provider egress runs, delivered bundle. THEN the ledger row flips done and P5 closes. G6 NO REGRESSION: full suite 634 passed + 28 skipped = 662 collected, 0 failed (measured after the last edit). G7 Hygiene: porcelain after the WORK commit; testing.md moved with the tests; ledger + design current; gdiff via ../scripts/step_gdiff. ## (4) LOCKs C-27-A b3ubot porcelain clean after each commit. C-27-B THE GATE CLOSES ON THE CEREMONY, NOT ON PHASE A: the ledger row stays `active` until check passes -- a machine may not declare a human-witnessed gate green. C-27-C DELIVERY NEVER COUPLES INTO CLOSURE (Q-25-A): closing freezes evidence offline; delivery is the operator's explicit, re-runnable act. No silent generate on close, ever, without a design amendment. C-27-D THE CEREMONY NEVER CLOBBERS: prepare refuses an existing dir and a duplicate UC.1; rehearsals use isolated homes. C-27-E standing locks inherited: C-26-B/C/D (id-space, guard- never-guesses, foreign-means-foreign), C-25-B/C/D, C-24-B, B-1/B-2/B-3/B-4/B-5. ## (5) Open questions Q-27-A Phase-B closure mechanics (DECIDED: when the operator's check passes, the closure session flips U5.5 -> done via `ledger close U5.5 ` + a §(0) addendum here naming the ceremony date -- the same backfill discipline as every hash). Q-27-B Relay-drafting (DEFERRED, named): ceremony V1 starts at the ratify gate over a seeded skeleton; a future variant lets the relay draft the skeleton itself (the V0 template validation + 2-attempt budget make that a friction risk unfit for a first ceremony). Q-27-C Ceremony spec target (DECIDED: the proposal names its own file -- first line of the paste-back; the check only requires SOME delivered bundle under generated/, so the operator may converge any grammar, not a scripted one -- it is THEIR loop now). Q-27-D Multi-line paste mechanics (FOUND LIVE at the first real relay prompt, FIXED same-session): bare input() reads one line; _parse_proposal requires path + content lines. DECIDED: the DEFAULT reader collects lines until a lone EOF sentinel (prompt says so); injected input_fns keep single-call semantics, so the whole contract suite is untouched. The first-ever interactive relay could not have been exercised by any test that injects I/O -- this is precisely the class of finding Phase B exists for. Q-27-E The check's clean-tree leg vs Q-25-A (FOUND by the FIRST real ceremony's own check, FIXED same-session): delivery is post-close by design, so the delivered generated/ tree is necessarily untracked after the closure commit -- the oracle demanded a contradiction. DECIDED: clean modulo the delivered bundle (anything ELSE dirty still fails). Two live-fire findings in one ceremony -- the gate earned its Phase B. ## (6) Acceptance - [x] Q-25-A resolved + recorded (2.1). - [x] Phase A oracle (3 legs) + trinity_gate.sh ALL PASS first invocation (2.2, 2.3, G1-G3). - [x] Ceremony prepare/check built + rehearsed isolated (2.4, G4); real data home untouched. - [x] U5.5 -> active via the engine's own ledger CLI; docs moved (2.5, G7); suite 634+28=662 (G6). - [x] PHASE B: the operator ceremony -- check PASS (8/8, 2026-07-22, independently re-verified) + the §(0) addendum; U5.5 closed via `ledger close` (G5, Q-27-A). THE GATE, AND P5, CLOSED HERE. ## (7) Hash backfill WORK commit (Phase A + ceremony + this file): (this commit) GDIFF commit (step.27.gdiff.txt): (HEAD) CEREMONY closure (Phase B, operator): (this commit) End of step.
