Migration
From v1
VCDesign v2 is not compatible with v1. Read v1 vocabulary and records as follows.
Source: implementation.md §6 "v1 からの移行". The table is the specification's, translated where it contains Japanese.
v1 vocabulary is used only on this page and in the archive. Every other page uses v2 vocabulary only.
Vocabulary and records
| v1 | v2 |
|---|---|
| action: fix | decision: proceed |
| action: reframe / defer / retire | decision: reframe / defer / retire |
| decision posture: commit | proceed (limit when narrowing the scope to stop immediately) |
| decision posture: reconsider | defer (the guard verdict is unknown) |
| decision posture: abandon | retire |
| decision_size: no_go / small_go / scale_go | retire (do not start) / proceed or limit / expand |
| Long-term judgment postures (small_go / defer_or_experiment / deny_or_reframe) | Settled at the judgment gate as one of the six words |
| RCL: Close / DeferToPool / Abort | proceed / defer / halt, then retire or defer. The core of RCL (a confirmed Δ stays under responsibility until a decision closes it; an undefined point at design time is also a Δ) is kept as core.yaml closure_loop |
| long_term_decision_gate, scale_gate, reframe / defer / retire_control | policies.yaml judgment_gate |
| tail_signals | spread_signals |
| action_history | decision_history |
| why_action | decision.basis |
| promise_broken | precondition_broken |
| unresolved_duration_exceeded, defer_stagnation, retirement_pending_too_long | stagnation |
| dependency_concentration, judgment_concentration | concentration |
| upside_signal_observed, tail_signal_absent_on_success, scale_beyond_recovery | spread_signal_observed, success_without_spread_signal, expand_beyond_recovery |
| long_term_judgment_metrics, repeated_reframe, reaffirmation_decay | Removed (replaced by the judgment gate and the core metrics) |
| Judgment Closure (ACCEPTED / DENIED / UNKNOWN) | A crossing is checked by the boundary guard verdict (pass / deny / unknown); a case's Δ is closed by the six decisions |
| Judgment Proposal, Responsibility Asset, Resolution, Resolution Handshake | AI output is a proposal until a human closes the decision. The scope, deadline and evidence of a closed decision are its declaration (blast_radius, next_review_at, reversal_window) and the decision log |
| RCA pattern, IDG pattern | guard and determinability in patterns/boundary-pattern.yaml |
| protocols/ (judgment-closure, resolution-handshake) | Removed (absorbed by the two rows above; crossings between organizations are the boundary's external_crossing) |
Where the old pages went
The site was restructured for v2: Japanese at the root, English under /en/. Old URLs remain as pages that point to the new location.
| Old page | Now |
|---|---|
| Home (v1) | Archive: the v1 home page. The v2 entry is Home |
| Reality Fit / Adaptive Loop Model | Merged into the AI extension |
| VC-AD, Why VC-AD?, Basic Constitution | Archive: earlier VC-AD pages. The current introduction is VC-AD |
| Agent Era (five layers), Maturity Profile, Gate / Tenure | The five layers and twelve principles are in the AI extension; gate and tenure in Core: responsibility. The Maturity Profile was removed in v2 |
| Constitution and Manifesto (on the home page) | Archive: the v1 home page |
English pages at the site root (e.g. /tddd/) | The same name under /en/ (e.g. /en/tddd/) |
Removed or merged specification files
v1 files such as specs/core/decision-posture.yaml, agent-era-model.md, ai-adaptive-loop-model.md, value-tenure-model.md, validation/vcdesign-maturity-profile.md, patterns/rcl/ and protocols/ were removed or merged in v2. See VCDesign-org/vcdesign#5 for the full change.
