Current Planning Position After Chapter 326

• Date/season: Wednesday night, 17 February 2027, in Sendai winter. The next passage window is expected around 25 February. Isha's next off-medication thyroid blood test is expected around mid-March. Kanno's birthday is 17 April.
• Thomas: twenty-four, healthy and physically ordinary. He works in the university international-support office, where the winter-arrival guide is designed to function through shared ownership. He has left judo, continues measured gym work and has begun modern target archery at beginner draw weights. The first Wednesday deliberately leaning toward his preferences has occurred; do not turn that reciprocal attention into a rigid weekly entitlement.
• Isha: twenty-five, fully human and in complete monitored Graves remission. She is off thiamazole, normally rests around 54-58 bpm and has returned to kyūdō, recreational climbing, occasional sprinting, weekly supportive strength work and controlled MMA contact. She completed one novice bout and does not currently want another merely because she can prepare. Do not reopen the disease or active System correction without new canon.
• Relationship: the Ch.310-322 argument arc is historic and repaired. Current Thomas speaks when a meaningful choice is being taken from him; current Isha can lead, tease and occasionally answer for him without every small familiarity becoming control. Private dominance remains wanted. Old drivers may recur under actual pressure, but the couple is not hovering on the edge of the same argument.
• Kanno: main Earth-side cast and mutual friend. Until Replaced has reached a second proof; a small first print run remains available. She knows the System's first health message and the couple's bounded interpretation, but not passage operations. Her age remains open.
• Magic/correspondence: Cleanse Lv.6 is current. Eight pages have been sent and six received. The protected post-Ch.278 passages are short and symptom-light, but safety procedure remains. The System's active repair of Isha ended in Ch.323; its broader monitoring or influence is unresolved.
• Other world: the sixth reply's station event establishes bounded transport of a healer and supplies through prepared known plates. The route is not a healer, a return route or an invitation to expand direct fantasy-world viewpoint.

Near-Term Hooks Still Unwritten

Late-February passage

• The opening around 25 February may bring a reply, permit another send or be deliberately left unused. Eight outgoing pages are already ahead of six replies; another receipt is narratively plausible but not compulsory.
• A reply may address the seventh or eighth page, Isha's illness/System wording, station work, family questions or ordinary Green Road life. Kelda cannot understand modern endocrinology unless the prior Common description supports it.
• PROTECTION ENABLED has reduced the six later observed events to roughly a minute or less. Keep the timer, recovery position, five-minute call threshold and ordinary emergency priority. Do not declare the transfer harmless.

Kanno and Until Replaced

• The second proof can lead to a forty-to-sixty-copy run, printer cost/colour/paper compromise, a launch table, a poor sales day, an unexpected reader or the decision to retain the work privately.
• Kanno's own 17 April birthday should not be displaced by another protagonist event. Her exact age can remain unspoken.
• Preserve her independent professional life and client-free-Saturday goal. Do not make every Kanno chapter an(other) fantasy disclosure or anime night.

Thomas-centred and shared Wednesdays

• Some Wednesdays may lean toward Thomas: archery, bookshops, a technical/local museum, cooking, his gym session or simple inactivity. Others may be mutual, displaced by ordinary life or left unscheduled.
• Thomas should be able to receive Isha's attention without refusing it as sacrifice. Isha should be able to choose it without turning the gesture into service or proof.
• His university guide can meet its first genuine delayed winter arrival, ideally through Sugiyama or another colleague rather than Thomas rescuing the process personally.

Isha after remission

• The next clinic result can confirm sustained remission at a longer interval. It should reduce medical attention rather than create another miraculous result scene.
• Kyūdō can deepen through formal timing, group movement, a poor day or a modest event. Prior bow skill accelerates but does not replace kyūdō practice.
• MMA can remain technical. A new bout should arise from desire and a credible opponent, not from recovered capacity needing use.
• Running and strength results are now established. Future scenes should prefer enjoyment, fatigue, interaction, limitation or scheduling over another measurement reveal.
• Climbing can carry work, community and movement pleasure. Isha's exceptional performance is baseline, not a weekly surprise.

Other standing threads

• Thomas's judo departure may produce relief, mild regret, a social encounter with Tanabe/Nakamura or no consequence at all. He may not return as secretly advanced.
• Matsuda's transfer can recur through a Sendai visit, Tokyo message, work/home issue or changing view of permanence. He remains uninformed about Daniel and the other world.
• Mai's immediate financial/research crisis is closed. Any return should be a later consequence, ordinary update or new institutional need, not repetition of the same decision.
• Miyake, Saitō, Arakawa, Yoshimura and the building remain available for reciprocal ordinary life. Mugi need not appear as a coda or System detector.
• Thomas and Isha can continue ordinary creative work around Fold No. 6, photographs, origami and food without turning every object into a thematic thesis.

Medium-Term Choices

• Whether Until Replaced becomes Kanno's first current publication, a private run or the seed of a more serious independent practice.
• Whether Thomas's fixed-term university role becomes a chosen professional direction, another post or evidence that he prefers process design to front-line case ownership.
• Whether Isha ever chooses a second MMA bout, and how kyūdō/climbing/strength coexist without every capacity becoming a career.
• Whether Thomas and Isha search further for Daniel Mercer, contact no one or confirm only enough to leave his family undisturbed.
• How slow letters alter grief without making Earth a waiting room or producing a return quest.
• How the larger home and their increasingly normal relationship shape discussion of guests, marriage or children while preserving that no decision is due.

Continuity Questions to Leave Open

• Is this Thomas's original Earth, a rewritten version or a neighbouring continuity?
• Did the incomplete final Revive create, select or merely reach the supplied identities?
• Did recorded-life Thomas and Isha exist independently before the transfer?
• What exact System process introduced the Graves implementation error, and why did it wait for Earth medicine before reporting or completing repair?
• After NORMAL OPERATION RESUMING, does the System still monitor either body, support only transfer/Cleanse, or influence any other plausible trait? No active medical correction remains.
• Do the two worlds pass time at the same rate?
• Did grief and guilt shape the reward form, or only the completed Hero objective?
• Are Thomas's cooking aptitude and Mugi's responsiveness independent plausible traits, continuity echoes or evidence of a wider process? Keep both non-magical/ambiguous unless prose establishes more.

Keep these as background pressure. Do not turn daily life into a System investigation, public supernatural escalation, harem structure, return quest, sequence of new powers or renewed medical crisis.

Planning Check

Before retaining a note here, ask:

• Is it unwritten and still genuinely available?
• Is it absent from the durable owner files?
• Does it offer a choice rather than silently pre-canonising an outcome?
• Has it been checked against recent prose, current witness scope and writing_style.md?
• Would removing it cause a likely future contradiction or erase a useful story route?

If not, delete it or migrate it.
